SPA AND POOL LIGHT AND LIGHTING METHOD

BACKGROUND OF THE INVENTION
Technical Field

The present invention generally is in the field of lighting devices and methods for spas, swimming pools, hot tubs, garden baths, and the like. The present invention more particularly is in the field of lighting devices and methods for illuminating the interior of and/or the area surrounding spas, swimming pools, hot tubs, garden baths, and the like. The present invention more particularly also is generally directed to the formation or insertion of a lighting device into, or through, the side wall(s) defining the water-containing portion of a spa, swimming pool, hot tub, garden bath, or the like.

Prior Art

Few applications derive more benefit from the addition of aesthetically pleasing and/or safety lighting than artificial bodies of water such as spas, swimming pools, hot tubs, garden baths, and the like. Modern developments in the art make pool lighting a perfect feature for pool and spa manufacturers to focus on. Users and owners of such structures, therefore, often desire the addition of lighting features and methods of lighting such structures.

The addition of a lighting feature or the illumination of a feature already present on or features added to an artificial body of water, for example, can provide a substantial decorative effect to or can provide a relaxing background visual experience for or can provide for increased safety in or around an artificial body of water. As the market for spas, swimming pools, hot tubs, garden baths, and the like grows, users desire more, different, better, more interesting, and more aesthetically pleasing lighting features and methods of lighting.

Many existing spas, swimming pools, hot tubs, garden baths, and the like include some type of lighting feature to add to the aesthetics of the device. In some existing spas, swimming pools, hot tubs, garden baths, and the like, the lighting feature is located on a feature of the device, such as on a waterfall or water jet, for providing an aesthetically pleasing water flow. In other existing spas, swimming pools, hot tubs, garden baths, and the like, the lighting feature is located on the decking or the exterior of such structures or as separate lighting devices, such as lamps, for providing ambient lighting or safety lighting. In yet other existing spas, swimming pools, hot tubs, garden baths, and the like, the lighting feature is located within the tub of water, such as in the wall, shell, or liner, also for providing ambient lighting and safety lighting.

In the pool and spa market, aesthetics are becoming more and more important. Aligned with this trend, high-end pool finishes are becoming more popular, and there are many to choose from. Some even have pebbles, stone, or glass beads mixed in with the plaster. When these aggregate materials are mixed with the plaster it creates a multi-tone finish that is not easily matched by a single-color component. Likewise, advancements in the printing and manufacturing of vinyl liners have led to the introduction of more intricate and ornate and sophisticated patterns and textures available for vinyl liner pools. Similar advancements in fiberglass technology have increased the aesthetic options for the shells of fiberglass pools. There is demand for pool components and equipment that compliment rather than stand out against these finishes. There is demand for components and equipment that are essentially invisible when installed so as not to detract from the overall aesthetic. Some components have been made to incorporate the pool finish into the component to help them blend in with the surroundings. However, there is not a similar solution available for pool and spa lights. Lights currently on the market have polished metal or color plastic trim to accent the feature in the pool. There is a need for a pool light that can be adapted to incorporate these high-end finishes into the light fixture to become invisible when the light is not on. Alternatively, there is a need for a new and unique lighting effect when the light is on. Some reasons why pool and spa lighting features have remained relatively unadorned are the challenges to overcome to arrive at the present invention. For example, lights create heat, which causes thermal expansion and contraction of materials, each at a different rate, which can create challenges when adhering different materials to one another, especially plaster and concrete. For another example, light lenses have been traditionally made of glass, which poses challenges when attempting to fasten another material to it. For yet another example, in pool/spa lighting typically “brighter is better” and it is counterintuitive to block or mask a center portion, or indeed any portion, of the lens. For still another example, although there have been many advancements in the electrical design of lighting over recent years, the way in which lighting features are installed into and interact with the pool or spa, such as in a niche, has remained effectively unchanged for decades.

Currently, known wet-niche lights are intended for installation in pools or spas with floors and walls formed of gunite or concrete (shotcrete) with a reinforcing bar (rebar) frame. The outside shape of the pool or spa is formed from a suitable material and in some cases, the excavated dirt wall will serve as the outside form. The shape of the inside wall of the pool or spa is skeletally formed from rebar that is bent to the desired shape. Niches, often as a metal or plastic form, are positioned between adjacent rebars such that the niche is held on preferably all four sides by sections of rebar. Once the niche has been securely positioned (wedged) in the rebar it must be securely tied to the rebar with tie wire. When the concrete or gunite is poured or shot to form the pool or spa wall, the niche remains as an indentation-like feature in the pool or spa wall. A hole or passageway can be formed in the back of the niche to allow wiring from outside of the pool or spa structure to extend into the niche for energizing a lighting feature.

The pool or spa must meet the requirements of the current National Electrical Code and all local codes and ordinances for a lighting feature to be properly installed. For example, for a wet niche below the surface of the water for containing an underwater light the lighting circuit must have a ground fault circuit interrupter (GFCI) for line voltage 120-volt models, and must have an appropriately rated circuit breaker. The junction box (or, for 12-volt models, the low voltage transformer) must be located at least eight inches above water level, at least four inches above ground level, and at least four feet from the edge of the pool or spa. The light fixture and all metal items within five feet of the pool or spa must be properly electrically bonded to a reliable point of grounding. The wet niche must be properly installed so that the top edge of the underwater light's lens is at least eighteen inches below the surface of the water in the pool or spa.

For vinyl lined metal wall, fiberglass panel, or fiberglass pools, a niche box can be installed by drilling and cutting out wall panel sections, inserting the niche box through the panel section from the interior of pool, and securing the niche box to the pool wall. For wood or fiber panel vinyl liner pools, a similar process can be carried out by cutting out a portion of the wall panel, inserting a niche box through the hole in the panel from interior of pool, and securing the niche box to the pool wall. However, once the lighting feature is inserted into the niche box, one typically is left with a common, aesthetically neutral lens. Thus, for this type of pool or spa, it would be advantageous to adorn the lens in a manner that blends with, contrasts with, or compliments the liner pattern.

There is, accordingly, a need for new and different lighting devices and methods for illuminating the interior of and/or the area surrounding spas, swimming pools, hot tubs, garden baths, and the like, and for lighting devices and methods for generating aesthetically pleasing light in, on, and around spas, swimming pools, hot tubs, garden baths, and the like. There also is a need for new and different lighting feature and methods of lighting artificial bodies of water and the like. There also is a need for an efficient and effective pool light that is minimalist in dimensions and materials, without sacrificing function, that also is aesthetically pleasing and can be well hidden or camouflaged, and that has different aesthetic designs and shapes, to maximize the lighting function as well as other forward-looking functions. It is to these needs and others that the present invention is directed.

BRIEF SUMMARY OF THE INVENTION

One exemplary embodiment of a spa light system comprises a base component having a body, a lens at a first end of the body, and a means for securing the base component to surrounding mounting surface, a decorative flange, and a light source. The body can be any shape, such as cylindrical, triangular, square, pentagonal, etc. in cross-section, as desired for aesthetic purposes. Similarly, the lens can any shape, such as flat, domed, wavy, ridged, faceted, etc. as desired for aesthetic purposes. The body can be structured for mounting on or through a shell wall, within niches in a solid wall, or in passages in a shell or solid wall. The mounting structure can comprise threads and nuts, tongues or tabs and slot or screw holes, weldments, etc. depending on the structure to which the invention is to be mounted.

In this exemplary embodiment, the lens is a translucent lens defining a desired shape with a recessed central region, a translucent region as a concentric band around the recessed central region, and a decorative flange as a concentric band around the translucent region. The decorative flange can be a part of the lens, can be a part of the body component, can be a separate component as a band around the lens, or can be a part of a separate housing for holding the lens. The flange also can be or have a recessed region. The recessed central region of the lens and/or the recessed region of the flange can be filled with a material to match or contrast with the pool or spa wall or shell, or the central recessed region of the lens can retain a cap having a desired design or pattern, including holes or punch-outs therethrough, or various other aesthetic devices. In this manner, the light emitted from the light source through the lens can be altered, patterned, or otherwise aesthetically changed.

Another exemplary embodiment comprises a lens mechanically retained by and/or in a pool niche. This embodiment of the light system preferably is mounted in or to a niche or niche box that is embedded into the pool or spa wall. In this embodiment, the light system of the present invention can be installed during the initial construction of the pool or spa or as a retrofit into a preexisting niche or passage in or through the pool or spa wall. Similarly, the spa light system of the present invention can be installed through a pool or spa shell or liner as a unitary item secured to the shell or liner or in a separate light housing separately secured to the shell or liner.

DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS
Generally

Embodiments and aspects of the present invention provide lighting devices and methods for illuminating the interior of, and/or the area surrounding spas, swimming pools, hot tubs, garden baths, and the like, that are not susceptible to the limitations and deficiencies of the prior art. The inventive concepts described herein, in certain non-limiting embodiments, allow for the formation or insertion or engagement of a lighting device into a pool or spa wall such that the lighting system/device provides functional illumination, and such that the non-illuminating portion of the lighting device is efficiently and effectively hidden from a user's view, or from contact with a user or pool equipment (e.g., a pool skimmer, a pool robots). More specifically, the lighting devices disclosed herein can be secured within niches or passages formed in the solid walls of in-ground pools and spas, secured within niche boxes secured to pool or spa shells or liners, or secured directly to a pool or spa shell or liner.

In preferred embodiments, the inventive concepts described herein allow for inserting, embedding, recessing, insetting, engaging, in certain non-limiting embodiments, a lighting device into, or through, the side wall(s) and/or floor defining the water-containing portion of an artificial body of water. The inventive concepts described herein also allow for a recessed, inset, and/or friction-fit grommet lighting device. The inventive concepts described herein also allow for a lighting device that is efficient and effective, that is minimalist in dimensions and materials, without sacrificing function, but that also is aesthetically pleasing and can be well hidden or camouflaged, and that facilitates different aesthetic designs and shapes, to maximize the lighting function, and to facilitate other parallel- or related-functions, such as creating synchronized lighting. This allows for a streamlining and simplifying alongside an expansion of the types of systems/devices capable of solving the problems inherent in the prior art.

As context and further background, one example of a light system generally is known for placement on or through a spa shell on the tub interior, either above, at, or below the water line of the water in the spa tub, so as to provide light or illumination for the interior of the spa tub. In this example, the spa light comprises a structured or molded base component having a hollow body that is mounted through the spa shell, a lens or light diffuser at a first end of the body, a nut or a friction fit wall grommet, or the like, for securing the base component on the spa shell; and a light source. Optionally, the spa light comprises a separate cap or is structured and shaped with a cap to partially cover the light source in the spa light, allowing the light to be directed. Also optionally, the spa light comprises a decorative cap having a decorative design thereon. This example also could be used on a pool or spa constructed with a vinyl liner or with a fiberglass wall.

Thus, as a general example, the inventive light system comprises a base component having a hollow body or interior, a front end, and a back end; a lens located at the front end of the body, the lens comprising a central area or portion and a peripheral area or portion surrounding the central area or portion; a flange surrounding the peripheral area or portion; a means for mounting or attaching the light system to a mounting surface or an attachment location; a light source contained within the base component, wherein at least a portion of the light emanating from the light source passes into the lens; and a means for interfering with or affecting the light emanating from the light source so as to prevent or alter a portion of the light from entering or passing through at least the central area or portion of the lens.

In another example, the light comprises a structured or molded base component having a hollow body that is mounted in a pool or spa wall, typically in a niche or passage in or through a solid wall such as gunite or concrete, a lens or light diffuser at a first end of the body, a tongue or tab for securing the base component on the wall or to the niche or niche box, a screw hole for accommodating a screw or other attachment means for further securing the base component on the wall or to the niche or niche box; and a light source. Optionally, the light comprises a separate cap or is structured and shaped with a cap to partially cover the light source in the light, allowing the light to be directed. Also optionally, the light comprises a decorative cap having a decorative design thereon.

The base component preferably comprises a one piece, generally hollow cup-like component having a closed or substantially closed bottom or back end, side walls, and an open top or front end, and may be formed at least partially out of a transparent, semi-transparent, or translucent material capable of transmitting light. The lens component is attached to the open top or front end of the base component normal to the axis of this generally hollow component. The open top or front end allows access to the generally hollow interior of the base component, for containing and accessing the light source.

The general structure of the lens component or the components making up the lens and flange is a common feature of all of the light systems of the present invention, irrespective of the type of pool or spa, and irrespective of the type of mount. The lens component, or light diffuser, allows the transmission of light from the light source to the tub interior of the spa. The lens component, or the components making up the lens component, comprises a translucent portion defining a desired shape with a recessed central region, a translucent region as a concentric band around the recessed central region, and a decorative flange as a concentric band around the translucent region. The decorative flange can be a part of the lens, can be part of the body or housing, can be a separate component as a band around the lens, or can be a part of a separate housing for holding the lens. The flange also can be or have a recessed region. The recessed central region of the lens and/or the recessed region of the flange can be filled with a material to match or contrast with the pool or spa wall or shell, or the central recessed region of the lens can retain a cap having a desired design or pattern, including holes or punch-outs therethrough, or various other aesthetic devices. In this manner, the light emitted from the light source through the lens can be altered, patterned, or otherwise aesthetically changed. The lens or light diffuser may be a permanent portion of the body or base component, being molded at the same time as the body or base component. The lens and body are preferably in a watertight arrangement to protect the light source and electronics from water ingress. Further, the body may be potted (filled with epoxy, RTV, silicone sealant, etc) for further protection. The light source may be an LED, a mini-bulb, or a more conventional or older bulb. The light source preferably is removable and replaceable.

The device may further comprise a tubular structure for holding the light source, such as a light emitting diode (LED) or other light-emitting device, depending on the embodiment of the invention use, which generally is dependent on the type of mount, namely, in-wall, in-niche, in-passage, or through-shell. The tubular structure can be an extension of the body and is generally coaxial with the body, whereby the hollow interior extends through the body and the tubular structure. The tubular structure is structured to contain the light source. As disclosed previously, the light source itself can be any light source suitable for use in a body of water, including, for example purposes only, one or more LEDs, one or more LED arrays, one or more LEDs mounted on one or more printed circuit boards (PCBs). The light source also can be designed to provide aesthetically pleasing light. The tubular structure allows for light emanating from the light source to be directed at the lens or light diffuser, generally centrally, such that the lens or light diffuser can be illuminated, and the illumination to be seen from the tub interior of the spa. Preferably, the optional cap will block a portion of the light illuminating the lens or light diffuser from being seen by the user. Optionally, the light source can be arranged in a ring or other pattern such that at least a portion of the light can escape through an area of the lens outside of the blocked center portion.

The lights are 12V AC but also may be provided in other electrical arrangements such as 120V AC, 24V AC, 24V DC, 12V DC. The lights are color-changing LED, but also may be white-only LED or incandescent lights. In LED embodiments, the lights are RGB and designed to sync with other lighting or lighted water features. In other embodiments, the lights may have a quick-disconnect feature to allow for a power cord to be removed from the light for easy service/replacement (cords typically are 50-100 ft long or more in the field, and have to be run through conduit to remove the cable and install a replacement).

In use on a pool or spa wall of the shell or liner type, the light may be attached to the wall at the manufacturing location, at the installation location, or after the pool or spa has been installed. In an exemplary embodiment, the base component is attached to the wall by drilling a hole through the wall, inserting the bottom or back end of the base component through the hole from the interior or wet/water side of the pool or spa such that the rear side of a mounting support of or proximal to the lens or light diffuser contacts the interior surface of the wall, screwing a nut onto the screw thread on the exterior of the body, and tightening the nut up against the exterior dry side surface of the of the wall such that the wall is sandwiched between the nut and the rear side of the mounting support and/or at least one gasket. The lens component then can be secured to the base component. In use on a solid pool or spa wall, such as an inground pool or spa with a gunite or concrete wall, the light may be inserted into a niche or passage in the wall, which niche or passage can be pre-existing or created specifically for the light. Inground pools and spas typically are made on-site and with niches or passages through their wall for mounting lights and other features. These pre-existing niches or passages typically are a standard size, and the present inventive light device can be made to be of such standard size for easy mounting in such pre-existing niches or passages.

Specific Exemplary Embodiments

With the above context in mind, a first exemplary embodiment of the inventive concepts provides an efficient, effective, and versatile light system for connecting to the controller and power-supply system of a pool or spa, wherein the light system comprises a lens component with at least a portion of the lens configured for receiving a “masking”, “hiding”, filler, or bonding material, whereby the light system attractively blends in with or compliments the pool wall(s) or floor. The light system is configured for inserting, embedding, recessing, and insetting into, or through, the side wall(s) or floor defining the water-containing portion of the pool or spa, and the light system is efficiently and effectively obscured or otherwise provided with an aesthetic feature, and allowing for a generally reduced level of contact with a user or pool equipment by having a thin profile.

A second exemplary embodiment of the inventive concepts provides a light system comprising a lens, with at least a portion of the lens configured for receiving a “masking”, “hiding”, filler, or bonding material, and with a decorative flange that bounds the perimeter of the lens. The decorative flange along the exterior and the “masked” or “hid” interior portion sandwich a translucent portion of the lens. The lens can be of any shape, including planar and domed, and circular or other geometrical shapes.

A third exemplary embodiment of the inventive concepts provides a light system comprising a Fresnel lens, with at least a concentric portion of the lens configured to receive a “masking”, “hiding”, filler, or bonding material, and with a concentric decorative flange that bounds the perimeter of the lens. Alternatively, the lens can have a prismatic or other pattern rather than a standard Fresnel pattern, depending on the desired lighting effect. The decorative flange along the exterior and the central interior portion of the lens sandwich a concentric translucent ring/halo/band of the lens. The central interior portion of the lens may be filled in the field by the pool builder with plaster, Pebble-Tec™ aggregate finish, concrete, gunite, tile, fiberglass, acrylic, vinyl, etc. to match or compliment the surrounding mounting surface around the lens, namely the pool or spa wall, shell, or liner. The concentric portion of the lens may contain ribs, barbs, anchors, or other features to help mechanically fasten or facilitate fastening of the “masking” or “hiding” material. Alternatively, an adhesive or various types of welding can be used to fasten the material within the central interior portion. The lens may be made in clear (glass or plastic) or with a translucent effect (etched glass or diffused clear plastic). The lens also may comprise features or patterns such as prisms, dimples, bumps, ribs, ridges, etc. to enhance, focus, diffuse, or direct the light to achieve a variety of lighting effects as the light passes through the lens.

A fourth exemplary embodiment of the inventive concepts provides a light system comprising a lens, with at least a concentric portion of the lens configured to receive a “masking”, “hiding”, filler, or bonding material, and with a concentric decorative flange that bounds the perimeter of the lens. The decorative flange itself can have at least a concentric portion configured to receive a “masking”, “hiding”, filler, or bonding material. At least the concentric portion of the decorative flange, along the exterior, and the concentric interior portion of the lens, sandwich a concentric translucent ring/halo/band of the lens. The concentric portion of the lens and the flange may be filled in the field by the pool builder with plaster, Pebble-Tec™ aggregate finish, concrete, gunite, tile, fiberglass, acrylic, vinyl, etc. to match or compliment the surrounding mounting surface around the lens. The concentric portion of the lens and the flange may be filled by the manufacturer with a separate cap or insert made of stainless steel, color coordinated plastic, or any other decorative material. The concentric recessed portions of the lens and the flange may be simple recesses. The concentric recessed portions of the lens and the flange may be concave, flat, or convex, but a preferred embodiment is concave. Material installed into the recess may be fashioned to be concave, flat, or convex.

Referring now to the drawings, wherein the showings are for purposes of illustrating the various embodiments of the present invention only and not for purposes of limiting the same, FIG. 1 is a perspective view of an exemplary embodiment of a light system 1 of the present invention. The light system 1 comprises a base component (not shown) having a tubular body (not shown) for mounting through or within a surrounding mounting surface 16 (a pool or spa shell, floor, liner, or wall, for example) (best seen in FIGS. 3, 5, 7, and 9), a generally flattened lens 2 at a first end 12 of the body, a mounting means (not shown) for securing the base component to surrounding mounting surface 16, a decorative flange 6, and a light source(s) (not shown).

This embodiment of the base component is a one-piece component. The base component has the lens 2 attached normal to the first open end 12 of the tubular body (best seen in FIG. 2). The first open end of the tubular body (not shown) preferably is open, allowing access to the hollow interior of the base component, for containing and accessing the light source(s). The lens 2 is formed out of a transparent, semi-transparent, or translucent material capable of transmitting light, and defines at least a central region 4 configured for receiving a “masking”, “hiding”, filler, or bonding material 10 and a visible region 8 that allows light to pass through the lens 2 and be seen. The decorative flange 6 bounds the outermost circumference or perimeter of the lens 2. The decorative flange 6 and the central region 4 of the lens 2 sandwich the visible region 8 of the lens 2 to effectively form a translucent ring/halo/band to be illuminated by the light source(s). The decorative flange 6 also is configured to have a recess 14 to receive a “masking”, “hiding”, filler, or bonding material 10 that is the same or different from the central region 4.

The lens 2, in this embodiment, is a translucent, disk-shaped, Fresnel lens defining a circular shape with a recessed central region 4. The translucent region 8 is a concentric band around the recessed central region 4 of the lens 2, and the decorative flange 6 is a concentric band around the translucent region 8. The decorative flange 6 can be a part of, that is a radial extension of, the lens 2. The decorative flange 6 alternatively can be a part of the base component, such as extending normal to the open end 12 of a light housing 35 as shown in FIG. 11, in which case the decorative flange 6 would be considered one of the components making up the lens component. The recessed central region 4 may be filled with an aesthetic material to match or compliment the surrounding mounting surface 16 around the light system 1 (best seen in FIGS. 3, 5, 7, and 9). The recess 14 in the decorative flange 6 also may be filled with an aesthetic material to match or compliment the surrounding mounting surface 16 around the light system 1 (best seen in FIGS. 3, 5, 7, and 9); however, in FIG. 1 the recess 14 in the decorative flange 6 is filled with the material 10 to match, compliment, or contrast with the recessed central region 4.

In this way: the light system 1 efficiently and effectively inserts, embeds, installs, or insets into, or through, the side wall(s) or floor defining the mounting surface 16. The lens 2 portion preferably is structured so as to be of a reduced profile, that is, flat, shallow domed, etc., so as to reduce contact with a user or pool equipment.

FIG. 2 is a sectional perspective view of the light system 1 of FIG. 1. The lens 2 is attached normal to the first open end 12 of the tubular body of the base component. The lens 2 defines a recessed central region 4 formed into, but not through, the material of lens 2, and taking the shape of a bulls-eye from a front-facing perspective. When the recessed central region 4 is filled with the filler material 10, the filler material 10 obfuscates or completely obstructs the illuminated recessed central region 4 of the lens 2. Alternatively, the filler material 10 may be at least in part translucent or patterned to provide for a glowing effect in the central region 4. For example, the filler material 10 also can comprise a mixture of different materials, or include holes, to produce a patterned effect. The filler material 10 may be fashioned to be concave, flat, or convex. A separate cap 24 (see FIG. 4) also may be installed to obfuscate or completely obstruct the illuminated recessed central region 4 of the lens 2, or to allow the light to be redirected. The decorative cap may have a decorative design thereon. The decorative cap 24 also can have holes or a punched design therethrough to allow for light to show through in a desired design or lighting effect.

The decorative flange 6 bounds the outermost circumference or perimeter of the lens 2 and defines a recessed region 14 formed by the material of the flange 6. The recessed region 14 of the decorative flange 6 also is filled with a material 10 to match or compliment the recessed central region 4. Unlike the filler material 10 of lens 2, the filler material 10 of the decorative flange 6 does not necessarily obfuscate or affect illumination of the flange 6. This is only because the decorative flange 6 of this embodiment does not illuminate separately from the lens 2. An illuminating flange 6, however, is envisioned as a possible feature of another embodiment.

In this way: the decorative flange 6 and the central region 4 sandwich the to-be-illuminated halo 8 of the lens 2; the halo 8 defines a first concentric band around the central region 4 bull's-eye, and the decorative flange 6 defines a second concentric band around the halo 8 and the central region 4 bull's-eye. Although the term “bull's-eye” is used herein, the light system 1 does not need to be circular, and other shaped “bull's-eyes” are contemplated, such as concentric triangles, rectangles, and other geometric figures.

FIG. 3 is a perspective view of another exemplary embodiment of a light system 100. The light system 100 is identical to the light system 1 of FIGS. 1-2, but for the differences described herein. The light system 100 comprises a disk-shaped lens 2 mechanically retained by a pool niche (see FIG. 20). The light system 100 is embedded into the wall/surrounding mounting surface 16, as is understood by a person having ordinary skill in the art. The lens 2 is securely engaged via a fastener 18, or the fastener 18 provides a single mounting point to the pool niche. The light system 100 has the halo 8 illuminated, and a light source is activated to illuminate the halo 8. The recessed central region 4 of the lens and the recessed region 14 of the flange 6 are filled with an aesthetic material 10 to match the surrounding mounting surface 16 around the light system 100.

The decorative flange 6, instead, is made of stainless steel, color coordinated plastic, or any other decorative material.

FIG. 4 also illustrates the use of a cap 24 that is installed to obfuscate the recessed central region 4 of the lens 2. In embodiments without the cap 24, the recessed central region 4 may be filled with stainless steel, color coordinated plastic, or any other decorative material to match or compliment the decorative flange 6. The recessed central region 4 may contain grooves, snaps, or other features to help mechanically fasten the cap 24, and also may contain ribs, barbs, anchors, or other features to help mechanically fasten other filler materials 10 such as particulate or aggregate material. Alternatively, the cap 24 or filler materials 10 may be fastened using glue, adhesive, epoxy, double-sided tape, or other means of fastening.

FIG. 5 is a perspective view of the light system 200 of FIG. 4 but with the cap 24 removed. The recessed central region 4 of the lens 2 is filled with the filler material 10 to completely obstruct the illuminated recessed central region 4 of the lens 2 and to match the surrounding mounting surface 16 around the light system 100. The halo 8 is illuminated and a light source is activated to illuminate the halo 8. The visible portion 20 of the flange 6 is comprised of a material and color to match or compliment the tones of the surrounding mounting surface 16.

FIG. 6 is a perspective view of another exemplary embodiment of a light system 300. The light system 300 is identical to the light system 200 of FIGS. 4-5, but for the differences described herein. The lens 2 of the light system 300 is about 6.0 inches in diameter, preferably between 5.0 and 7.0 inches in diameter, while the lens 2 of the spa light system 200 is about 10.0 to 11.0 inches in diameter, preferably between 9.0 and 13.0 inches in diameter. Either system 200 or 300 are capable of universally replacing other third-party lights made by competitors, whether with or without an adapter. For example, the decorative flange 6 portion preferably is sized to extend and cover the niche or existing wall fitting.

FIG. 7 is a perspective view of the light system 300 of FIG. 6 but with the cap 24 removed and a filler material 10 inserted into the recess 4.

FIG. 8 is a perspective view of another exemplary embodiment of a light system 400. The light system 400 is identical to the light system 300 of FIGS. 6-7, but for the differences described herein. The lens 2 of the light system 400 is about 1.5 to 5.0 inches in diameter, with a common size being 2.25 inches in diameter. A common niche or passage size in about 1.5 inches in diameter, and the housing or body should be sized so as to fit within the niche or passage. The cap 24 is made of stainless-steel material 26 to completely obstruct the illuminated recessed central region 4 of the lens 2.

FIG. 9 is a perspective view of the light system 400 of FIG. 8 but with the cap 24 removed and a filler material 10 inserted into the recess 4. The system 400 is capable of universally fitting into proprietary or third-party standard wall fittings or pipes.

FIGS. 10-19 provide additional detail for the embodiments of the invention in, and described in connection with, FIGS. 1-9.

FIG. 10 is a perspective side view of the light system 1 of FIG. 1 for use in a standard inground pool niche. The light system 1 comprises a connector 31, preferably a waterproof quick connect/disconnect connector for connecting the light system to an electrical system for the pool or spa and a cable 32 to the lighting array and internal electronics. The connector 31 connects to a mating connector on a longer (e.g., 50-100 foot) cable (not shown) in the conduit or passage. The longer cable connects to the electrical system for powering the pool or spa, including the light system 1. The connector 31 allows for the light system 1 to be replaced without having to pull the longer 50-100 foot cable out of the conduit or passage and fishing in a new 50-100 foot cable with the new replacement light system 1. Replacing the longer cable can be difficult and the present invention helps in avoiding such a need for replacing the longer cable.

A light housing 33 is constructed comprising a cup-like structure for containing the lighting array and the internal electronics. A lens 38 is sealed onto the light housing 33 using known devices, such as gaskets or seals 34 (not shown in FIG. 10). The light housing 33 comprises a light flange 35 extending radially outwards from the cup-like structure as previously described, with the light flange 35 comprising a recess 14 for containing an aesthetic surface material 37 such as material 10. The lens 38 also comprises a recess 4 for containing an aesthetic surface material 37. If desired, the aesthetic surface material may match the surface material of the spa wall. One or more mounting screw holes 36 can be provided for mounting the light flange 35 to the spa wall.

FIG. 11 is a perspective side sectional view of the light system 1 of FIG. 10. In FIG. 11, both a preferred embodiment of the contour of the light flange 35 and the lens 38 and of the lighting array and the internal electronics 82 of the device 1 can be seen. The light flange 35 has a generally U-shape contour with a bottom and side walls providing a recess 14 structure for holding the aesthetic surface material 37. Similarly, the lens 38 comprises a central recess 4, circular in this embodiment, for holding the aesthetic surface material 37 or some other aesthetic device, such as a cap 24 or covering. The cap 24 or covering can be a different material, such as stainless steel, colored plastic, vinyl, acrylic, fiberglass, etc. The lens 38 comprises an unobstructed portion 2 for allowing light to pass through and be seen.

As shown in the exemplary embodiment of FIG. 11, the lighting array and internal electronics 82 comprise at least one LED array 39 mounted on at least one printed circuit board 40 and various known electronic components 41 for providing electrical current to and operating the LED array 39. The LED array 39 and the printed circuit board 40 are arranged within the light housing 33 such that light emitted from at least a portion of the LED array 39 is emitted through and/or can be seen through the lens 38 when the LED array 39 is energized. The LED array 39 may be arranged to be hidden behind the obscured center recess 4, which can provide a more muted lighting effect for accent lighting. Alternatively, the LED array may have directional optics to direct light out around the obscured center recess 4 for a brighter effect. Cable 32 extends through a hole 84 in the base of the light housing 33 and is held in place by a known device such as a strain relief fitting 42. Various electronics 82 components can include, for example, heat sinks, transformers, additional printed circuit boards, timers, switches, etc.

FIG. 12 is a perspective side view of the light system 1 of FIG. 10 without the aesthetic surface material 37 and showing optional features to mechanically hold the aesthetic surface material 37. Such optional features are shown in the form of tabs 43 to which the aesthetic surface material 37 can secure as the aesthetic surface material 37 dries during installation. The tabs 43 can be located both within the recess of the light flange 35 and within the recess in the lens 38.

FIG. 13 is a perspective side view of the light system 1 of FIG. 10 without the aesthetic surface material 37 and showing optional features in the form of tabs 43 within the recess 14 and a lip 44 (see FIG. 19 for detail) on the upper edges of the recess 14 wall to mechanically hold the aesthetic surface material 37 within the recess 14. The upper lip 44 can curve inwardly towards the center of the recess such that the aesthetic surface material 37 dries underneath the upper lip 44 during the installation process. Other features for retaining the aesthetic surface material 37 within the recesses 4, 14 also are suitable.

FIG. 14 is a side sectional view of the light system 1 of FIG. 10. Similar to FIG. 11, in FIG. 14, both a preferred embodiment of the contour of the light flange 35 and the lens 38 and of the lighting array and the internal electronics 82 of the device 1 can be seen in more detail. The light flange 35 has a generally U-shape contour with a bottom and side walls providing a structure for holding the aesthetic surface material 37 (not shown in FIG. 14). Similarly, the lens 38 comprises a central recess 4 for holding the aesthetic surface material 37 or some other aesthetic device, such as a cap 24 or covering. The lens 38 comprises an unobstructed portion 2 for allowing light to pass through and be seen. As shown in greater detail in FIG. 14, the lighting array and internal electronics 82 comprise at least one LED array 39 mounted on a printed circuit board 40 and various known electronic components 41 for providing electrical current to and operating the LED array 39. The LED array 39 and the printed circuit board 40 are arranged within the light housing 33 such that at least a portion of the LED array 39 can be seen through the lens 38 when the LED array 39 is energized, and can be considered generally on a parallel plane to the lens 38. Cable 32 extends through a hole 84 in the base of the light housing 33 and is held in place by a known device such as a strain relief fitting 42.

FIG. 14 also shows a retainer tab 46 that can engage with a corresponding slot in the niche, the niche wall, or the pool or spa wall to attach and lock the light housing 33 or the light flange 35 (or the lens 38 with a light flange 35 combination as discussed in connection with FIG. 15) to the wall. For example, as discussed in connection with FIGS. 23A-D, the light flange 35 portion can be installed on the pool or spa by holding the light system 1 at an angle to the niche or niche box 90, engaging the retainer tab 46 into the slot 92 of the niche, pivoting the light system 1 into the niche, and then installing a mounting screw through the mounting screw hole 36 into the pool or spa wall.

FIG. 15 is a side sectional view of a light system 1 similar to that of FIG. 10, but with a single-component lens 38 and flange 35 embodiment. In the embodiments shown in FIGS. 12-14, the light flange 35 and the lens 38 are separate components, with the lens 38 being mountable within a central opening of the light flange 35. Alternatively, as shown in FIG. 15, the light flange 35 and the lens 38 can be a single component, made out of transparent or translucent lens material, that is secured onto an open top portion 12 of the light housing 33. In such a single component embodiment, which can be considered a lens 38 with a lens flange 35, the lens 35 is essentially divided into three portions, a central recess portion 4, a middle lens 2 portion and an outer flange 35 portion, all made of lens material. The three portions can be separated by raised walls 45 so that the aesthetic surface material 37 within the central recess portion 4 and the outer flange 35 portion will not migrate into the middle lens 2 portion. The lens 38 with a lens flange 35 combination can then be attached to the light housing 33 with threads, ultrasonic welding, heat welding, bayonet locks, adhesives, or other known methods of attachment, such as attachment foot 96 extending axially from the back of the lens 38.

FIG. 16 is a perspective side view of a nicheless light system 101 suitable for use in the present invention. This nicheless light system 101 typically is for mounting directly in a gunite or concrete wall of a pool or spa, and not in a niche. More specifically, when the pool or spa is manufactured, the light housing 33 is attached to rebar and the wet or unhardened gunite or concrete is applied around the light housing 33, which remains as a permanent feature when the gunite or concrete sets and hardens. The nicheless light system 101 comprises similar or analogous components as the light system 1 shown in FIG. 10, such as a connector 31, a cable 32, lighting LED array 39 and internal electronics 82, a light housing 33, and a lens 38 with a light flange 35 and/or at least one recess 4, 14 for containing an aesthetic surface material 37. The light housing 33 further comprises a water stop 154 extending radially outwardly from a generally central location on the light housing 33. The water stop 154 both helps retain the light housing 33 in the gunite or concrete and also provides a barrier or stop helping to prevent water seeping between the gunite or concrete and the outer surface of the light housing 33 from seeping or leaking out of the pool or spa.

FIG. 17 is a perspective side sectional view of the nicheless light system 101 of FIG. 16. Generally, the internal arrangement of components for the nicheless light system 101 also is similar or analogous to the internal arrangement of components for the light system 1 of FIG. 10. However, an exemplary embodiment of the nicheless light system 101 can comprise three primary components: light housing 33 component, lens 38 and lens mounting component 52, and tubular light structure 54. Tubular light structure 54 contains the light array and electronic components, such as the LEDs 39 and printed circuit board(s) 40 at one end and the cable 32 extending out the opposite end. At the light array end, tubular light structure 54 has a male thread for cooperating with a female thread on the lens 38. In this manner, tubular light structure 54 can be releasably secured to the lens 38 to create a water-tight or water-proof structure to protect the LEDs 39, printed circuit board 40, and the other electronic components located within the tubular lighting structure 54. As one of ordinary skill in the art will understand, the tubular light structure 54 and the threaded region of the lens 38 can be circular in cross-section, with the light housing 33, flange 35, and lens 38 itself being different geometrical configurations. In this manner, a common tubular light structure 54 can be used in combination with various different shaped light housings 33, flanges 35, and lenses 38.

Light housing 33 is a generally hollow tubular component mounted within the gunite or concrete wall. Light housing 33 has an internal female thread on the pool or spa end of the light housing 33 for cooperating with a male thread on or attached to the lens 38, or on a lens mounting component 52 (see FIG. 17 and the description thereof). In this manner, lens 38, along with tubular light structure 54, can be releasably secured to the light housing 33 and thus mounted in the pool or spa wall. Thus, tubular light structure 54 is screw-mounted to lens 38, and the combination lens 38 and tubular light structure 54 can be screw-mounted to light housing 33, or snapped into the light housing 33 (see FIG. 17 and the description thereof), or even welded or adhesively affixed to the light housing 33 for a more permanent manner of attachment. The releasable configurations result in the ability to replace the lens 38 should the lens 38 break or if a new, different lens 38 is desired, and to replace the light array and electronic components should either of them fail. Alternatively, any or all of the components can be permanently attached to each other by, for example, adhesives or welding.

FIG. 18 is a perspective side view of a lens 38 for holding aesthetic surface material 37 suitable for use with the nicheless embodiment of the present invention, such as in combination with the nicheless light of FIG. 16. In this embodiment the lens 38 and light flange 35 are part of a single, unitary component constructed of lens material, such as a transparent or translucent material. Lens 38 comprises a component similar to the lens 38 shown in FIGS. 1-2 and 10-15, namely, a lens 38 with at least one recess for holding aesthetic surface material 37. Specifically, Lens 38 of FIG. 18 has a lens disk 56 central recess 4, a middle lens component 2, an optional outer annular recess 14, and a light flange 35 portion.

Lens 38 further comprises a mounting cylinder 58 extending perpendicular from a back side of the lens disk 56, namely the side of the lens disk 56 that does not face into the interior of the pool or spa. Depending on the shape and structure of the pool or spa, or of the lens 38, mounting cylinder 58 can extend at various angles form the lens disk 56, but preferably extends at an angle of 45-90 degrees, and more preferably an angle of 60-90 degrees. Mounting cylinder 58 comprises an internal female thread for cooperating with the external male thread of tubular light housing 54 as previously disclosed.

Mounting cylinder 58 further comprises a means for mounting the lens 38 onto the light housing 33. The means for mounting may comprise an external mounting surface 66 for attaching to a lens mounting component 52, shown in FIG. 17. The lens mounting component 52 is a sleeve-like structure that fits over and is preferably secured to the external mounting surface 66 using a bayonet or tab lock device (not shown, but known in the art). For example, the lens mounting component 52 can comprise a male thread on the external surface of the sleeve-like structure and tabs or bayonet features on the internal surface of the sleeve-like structure. In this embodiment, the lens mounting component 52 screws into the light housing 33, and the lens 38 with the tubular structure 54 attached thereto is snapped into the lens mounting component 52. In this manner, tubular light structure 54 can be releasably secured to the lens 38 to create a water-tight or water-proof structure to protect the LEDs 39, printed circuit board 40, and the other electronic components located within the tubular lighting structure 54. The external mounting surface 66 of the mounting cylinder 58 is pushed past the tabs or bayonet features, which undergo plastic or elastic deformation, until the external mounting surface 66 passes completely by the tabs or bayonet features, at which point the tabs or bayonet features snap back so as to hold the mounting cylinder 58 within the lens mounting component 52.

Lens mounting component 52 has an external male thread for cooperating with the internal female thread of light housing 33 for releasably securing lens 38 and lens 38 and tubular light structure 54 to light housing 33. Alternatively, instead of external mounting surface 66, mounting cylinder 58 can comprise an external male thread directly on the outer surface of mounting cylinder 58 for cooperating directly with the internal female thread of light housing 33. The lens mounting component 52 can be a part of the flange 35 or faceplate whereby a flange 35 or faceplate can be used that comprises the lens mounting component 52 as a back part, extending normal or at an angle from the flange 35 or faceplate, so that the flange 35 or faceplate, as a separate part from the lens 38, can screw into the light housing 33, and the lens 38 can tab- or bayonet-mount into the flange 35 or faceplate. In this manner, the flange 35 or faceplate can cover and hide preexisting spaces, components, or features.

The lens disk 56 optionally may comprise openings 60, typically through the outer annular recess 14 regions. These openings 60 can be used for anchoring a removal tool for removing the lens 38 or the lens 38 and tubular light structure 54 from the light housing 33. Additionally, these openings 60 can allow water to pass through lens 38 into the fitting or the passageway through the gunite or concrete for cooling the light system 101. The use of an external mounting surface 66, which separates the lens mounting component 52 from the outer surface of the mounting cylinder 58, allows for a volume between the mounting cylinder 58 and the lens mounting component 52 in which the cooling water can access through the openings 60.

FIG. 19 is a side sectional view of the lens of FIG. 18 with an enlarged view of the central recess for holding aesthetic surface material 37 Optional lip 62 extending inwardly at the outer surface of the lens 38 disk surrounding the central recess provides for an additional means for retaining aesthetic surface material 37 within the central recess. The lip 62 may be continuous or discontinuous.

FIG. 20 is a side sectional view of a niche in a pool or spa wall for holding a niche version of the light system 1 of the present invention. Niche 70 is pre-formed in the wall 72 during the original installation of the pool or spa, or can be formed afterwards. Niche 70 can be any size and shape, and often is of a standard size and shape for holding light features or other features. Niche 70 often has a passageway 74 at the rear of the niche 70 and extending out of the pool or spa structure for allowing electrical wiring 76 to pass into the niche 70. The spa light system 1 can be inserted into and secured within the niche 70 as disclosed previously, with cable 32 connected to wiring 76 via connector 31. Thus, spa light system 1 can be removably and replaceably inserted into niche 70.

FIG. 21 is a side sectional view of a nicheless, through-wall mounting for a through-wall version of the light system 101 of the present invention. Passageway 80 is pre-formed in the wall 72 during the original installation of the pool or spa, or can be formed afterwards. Passageway 80 can be any size and shape, and often is of a standard diameter for holding light features or other features. Passageway 80 extends out of the pool or spa structure for allowing electrical wiring 76 to pass through passageway 80. The light system 101 can be inserted into and secured within the passageway 80 as disclosed previously, with cable 32 connected to wiring 76 via connector 31. Thus, light system 1 can be removably and replaceably inserted into passageway 80.

In either of the installation manners shown in FIGS. 20-21, the lens 38 preferably is mounted flush to the pool or spa wall surface. However, due to the structure of the lens 38, the lens 38 often will protrude somewhat or slightly into the pool or spa interior. After the light system 1, 101 is mounted in the pool or spa wall and the lens 38 is attached to or located at the desired place, the lens 38 will contain aesthetic surface material 37 identical to or complimentary with the pool or spa wall and therefore the lens 38 will blend in with the pool or spa wall, creating a pleasing aesthetic look. When the light system 1, 101 is energized, light will be emitted from the lens 38 in the areas not covered by the aesthetic surface material 37 and create an aesthetically pleasing light display. Also, the aesthetic surface material 37 may at least in part be translucent to create a glowing light effect.

FIG. 22 is a side sectional view of through-shell mounting for a shell or liner mounted version of the light system 1 of the present invention similar to that shown in FIG. 10. The light system 1 comprises a connector 31, preferably a waterproof quick connect/disconnect connector for connecting the light system 1 to an electrical system for the pool or spa (an example of which is disclosed previously) and a cable 32 to the lighting array with LEDs on a printed circuit board and other internal electronics. A light housing 33 is constructed comprising a cup-like structure for containing the lighting array and the internal electronics. A lens 38 is sealed onto the light housing 33 using known devices, such as gaskets or seals 34. The light housing 33 comprises a light flange 35 extending radially outwards from the cup-like structure as previously described, with the light flange 35 comprising a recess 14 for containing an aesthetic surface material 37. The lens 38 also comprises a recess 4 for containing an aesthetic surface material 37 or a cap 24 or covering. The housing 33 in this embodiment is in part cylindrical for fitting through a round hole in a shell wall. A male thread is formed on the outer surface of the cylindrical housing 33 wall to cooperate with the inner surface of a cooperating securing nut. The housing 33 is inserted through the hole 122 in the shell wall 120 and the nut 124 is tightened via the cooperating threads such that the shell wall 120 is sandwiched between the nut 124 and the flange 35, thus securing the housing 33 onto the shell wall 120. Another gasket 126 or seal can be placed between the flange 35 and the shell wall 120 for further waterproofing. This embodiment does not require a tubular structure 54 separate from the housing 33.

FIGS. 23A-D are schematic side perspective views of a manner for installing an embodiment of the invention in a niche box 90, with FIG. 23A being a view of a niche box 90, FIG. 23B being a view of the light system 1 and cable 32 ready for placement in the niche box 90, FIG. 23C being a view of the light system 1 being attached to the niche box 90 using a tab 46 and then rotated upwards for securing, and FIG. 23D being a view of the light system 1 secured to the niche box 90 with a screw. The niche box 90 is mounted in the solid wall of a pool or spa, often by attachment to the rebar structure of the pool or spa wall during the construction phase of the pool or spa, and sometimes into a hole or passageway drilled into the pool or spa wall after construction. As can be seen in FIG. 23A, the niche box is a cup-like structure having a hollow interior, an upper connecting means and a lower connecting means. The upper connecting means can be a screw hole 36 and the lower connecting means can be a slot 92 for accepting a tab 46. The bottom of the cup-like niche box 90 has a port (not shown) for allowing electrical and/or other utility cabling to pass through. In FIG. 23B, an electrical cable 32 extends from the bottom of the niche box 90 for connecting with the light system 1 to supply power to the light system 1.

FIG. 23C illustrates a method for attaching the light system 1 to the niche box 90. Holding the light system 1 at an angle, a tab 46 or tongue on the flange 35 of the light system 1 is inserted into the lower connecting means slot 92 of the niche box 90. Once the tab 46 or tongue is inserted in to the slot 92, the light system 1 is rotated towards the open end of the niche box 90 so as to cover the opening as shown in FIG. 23D. Once in place covering the opening of the niche box 90, a screw can be inserted through the screw hole 36 in the flange 33 and into the upper connecting means screw hole 36 of the niche box 90, thus securing the light system 1 to the niche box This same manner of attachment can be used to attach the light system 1 directly to a pool or spa wall that has a niche or passage formed therein, without the use of a separate niche box 90. For this, the niche or passageway itself would comprise a slot 46 and a screw hole 36 at the appropriate locations.

FIG. 24 is a perspective side view of the light system 1 of FIG. 1 having a square flange and a round lens. The LED array 39, printed circuit board 40, and internal components for these embodiments remain the same, as this figure is to illustrate that different shapes can be applied to the visible components. However, the LED array 39 and printed circuit board 40 can be made to match any shape of the flange 35 and lens 38.

FIG. 25 is a perspective side view of the light system of FIG. 1 having a square flange and a square lens. This figure also illustrates that different shapes of the LED array 39 and printed circuit board 40 also can be used. The mechanical fastening features to hold in the aesthetic surface material, the aesthetic surface material itself, or the caps in these embodiments can be structured to fit the now square recesses.

The light systems described herein may be used on almost any artificial water body. While the light system is described in connection with a pool and spa, it is understood that the light system may be used on spas, swimming pools, tubs, jacuzzis, and the like. One of ordinary skill in the art can modify the light system without undue experimentation so that it can be placed on almost any artificial water body. Thus, the invention may be installed on pool or spa walls or shells to provide for the addition of aesthetically pleasing, decorative, architectural, and/or safety light to a pool or spa or the area surrounding a pool or spa.
