The present invention generally relates to lighted posts and, more particularly, to lighted posts that may be used as bollards or pathway lights.
Lighted posts have been used for years to light the entrance way of a building or a residence or to light an area, such as a walkway or deck, including a pool deck. Most residential lights are formed from a support post and a housing that is mounted to the post. The housing typically houses one or more lights, such as halogen lights or the like, and incorporates light transmitting openings through which the light passes to illuminate the ground or the light post itself. Some light transmitting openings have covers or lenses to diffuse or direct the light. Other openings are left uncovered. A lighted post may also be formed from a tubular member that provides a support, as well as a housing for the light. These lighted posts tend to be used in commercial applications.
However, the light sources used in conventional lighted posts produce a significant amount of heat and, further, consume a considerable amount of energy. If the light sources are energized for a significant length of time the housing may become quite hot. Consequently, the housings typically incorporate louvers to allow air flow through the housing to cool the air in the housing and, hence, cool the housing. These louvers or openings, however, tend to detract from the appearance of the housing. In addition, the light is generated by discrete light sources that results overlapping puddles of light, which produce a non-uniform light intensity.
Consequently, there is a need for a lighted post that can be assembled in a manner to eliminate the need for louvers and further to reduce its power consumption.
Accordingly, the present invention provides a lighted post that can be assembled in a manner to reduce or minimize the bug and dirt intrusion into the post and, further, configured in a manner to reduce its power consumption.
In one form of the invention, a lighted post includes a stanchion, a light assembly, and a light transmitting opening provided at the wall of the stanchion. The light assembly includes a light source and a body with a light emitting surface. The light assembly is adapted for coupling to a power source for powering the light source so that when powered, light from the light source is directed into the body and is directed from the body through the light emitting surface. The light assembly is mounted so that the body is located in the light transmitting opening wherein the light emitting surface, which faces outwardly from the stanchion, directs light outwardly from the stanchion.
In one aspect, the stanchion comprises a tubular member.
According to another form of the invention, a lighted post includes a tubular member, a cover, and a light assembly. The tubular member has an upper open end, which is closed by the cover, a lower open end, which is adapted to mount to a fixed surface, a wall, and a chamber defined by the wall. The light assembly has a light source and a body with a light emitting surface and is adapted for coupling to a power source for powering the light source. When powered, light from the light source is directed into the body and is directed from the body through the light emitting surface. A light transmitting opening is provided at the wall of the tubular member, with the light assembly mounted so that the body of the light assembly is located in the opening and so that the light emitting surface, which faces outwardly from the tubular member, directs light outwardly from the tubular member.

The light assembly includes a light emitting diode and a body with a light emitting surface. The light assembly is adapted for coupling to a power source for powering the light emitting diode so when powered, light from the light emitting diode is directed into the body and is directed from the body through the light emitting surface. In addition, a light transmitting opening is provided at the tubular wall of the tubular member, with the body located at the light transmitting opening so that the light emitting surface faces outwardly from the tubular member through the light transmitting opening to thereby direct light outwardly from the tubular member. Further, the light transmitting opening is substantially closed and the tubular member is substantially free of any unclosed openings wherein the chamber remains substantially free from intrusion from bugs.
In yet another form of the invention, a lighted post includes a base, a tubular member, and a light assembly. The light assembly includes a light emitting diode and a body with a light emitting surface and is adapted for coupling to a power source for powering the light emitting diode. When powered, light from the light emitting diode is directed into the body and directed from the body through the light emitting surface. The tubular member includes an access opening that is covered by a panel, which includes a light transmitting opening. The light assembly is mounted so that its body is located at the light transmitting opening to thereby direct light outwardly from the tubular member through the light transmitting opening.
In another form, a lighted post includes a support, a light assembly, and a cover that is mounted to the support and that forms a cover for the light assembly. The light assembly includes a light source and a body with a light emitting surface. The light assembly is adapted for coupling to a power source for powering the light source so that when powered, light from the light source, which is directed into the body, is directed from the body through the light emitting surface. The body is configured to diffuse the light in a manner so that when light is emitted by the light emitting surface it has a substantially uniform light intensity pattern. The light assembly is mounted in the cover at the support, with the light emitted from the light assembly's light emitting surface directed downwardly toward the surface on or in which the lighted post is mounted. Further, the cover is adapted to substantially seal the light assembly in the cover.
In one aspect, the support comprises a tubular member, including a square tubular member or a round tubular member, with an open upper end. The cover is mounted over the open upper end and closes and substantially seals the open upper end of the support.
In another aspect, the body of the light assembly comprises an elongated body, such as a waveguide, which extends around at least a portion of the perimeter of the support post to provide a substantially uniform pattern of light around at least a portion of the lighted post. In preferred form, the light assembly includes at least two bodies and at least two light sources, with the two bodies configured to substantially extend around the full perimeter of the support to thereby form a substantially uniform pattern of light around the lighted post.
According to another form of the invention, a lighted post includes a support, a cover, and at least one light assembly. The support is adapted to mount on or in a ground surface or a base and comprises a tubular member with an upper open end, which is closed by the cover, and a lower open end. The light assembly has a light source and a body with a light emitting surface and is adapted for coupling to a power source for powering the light source. When powered, light from the light emitting surface is directed downwardly to illuminate at least the ground surface or base with a substantially uniform pattern of light.
In one aspect, the tubular member comprises a plastic tubular member, such as reinforced plastic. The tubular member may comprise a rectangular tubular member, such as a square tubular member, or a round tubular member. In a further aspect, the cover comprises a plastic cover.
In yet a further aspect, the lighted post includes a bracket which mounts the cover to the tubular member. The light assembly may be positioned between the cover and the bracket, for example.
According to yet a further aspect, the light assembly is mounted to the bracket with its light emitting surface facing downwardly toward the ground surface.
According to yet another form of the invention, a lighted post includes a tubular support, a light assembly, and a cover that is mounted to the upper end of the support. The tubular body or the cover includes at least one transverse opening that extends through the wall of the support or the cover to form a light transmitting opening. The light assembly includes a light source and a body with a light emitting surface, which is positioned in the light transmitting opening. The light assembly is adapted for coupling to a power source for powering the light source so that when powered, light from the light source, which is directed into the body, is directed from the body through the light emitting surface and directed outwardly from the lighted post through the light transmitting opening.
For example, the light transmitting opening may comprise an elongate opening oriented such that its longitudinal extent is aligned with the vertical axis of the tubular support.
In one aspect, the tubular support includes an open upper end. The cover is mounted over the open upper end and closes and substantially seals the open upper end of the support. In a further aspect, the cover includes a downwardly depending cylindrical wall that is mounted to the tubular support. For example, the light transmitting opening may be provided in the cylindrical wall of the cover. Optionally, the cylindrical wall may include a plurality of light transmitting openings, with each opening associated with a light assembly.
In a further aspect, the cover is adapted to substantially seal the light assembly in the support.
In any of the above forms of the invention, the light source may comprise a plurality of light emitting diodes, such as a plurality of high intensity light emitting diodes. The body of the light assembly may comprise an elongated body, and, further, may act as a waveguide. In preferred form, the waveguide has a curved outer surface, which forms the light emitting surface for fanning the light from the light emitting diodes outwardly. According to yet another aspect, the lighted posts further may include a bracket, with the body of the light assembly including a groove and with the bracket extending into the groove for mounting the light assembly. In yet another aspect, the body of the light assembly substantially fills the opening wherein the post is substantially free of unclosed openings. The light emitting surface may be recessed in the opening or may project outwardly from the opening, or may be flush with the exterior.
In addition, in any of the above forms of the invention, the lighted post may include a plurality of light assemblies and a corresponding plurality of light transmitting openings. Each of the light assemblies has a light source and a body, which may act as a wave guide. Further, the body or bodies are preferably positioned at a respective light transmitting opening so that each of the light emitting surfaces faces outwardly from the post at the respective light transmitting opening. In a further aspect, the light assemblies may be mounted using a single bracket. In addition, each of the bodies may have a groove to provide an engagement surface for mounting the light assembly. For example, in one aspect, the bracket extends into the respective grooves of the bodies of the light assemblies to thereby mount the light assemblies to the post. For example, the bracket may comprise a plate with a plurality of slots extending into the plate from an edge of the plate. The slots form a plurality of spaced lateral edges, with the bodies of the light assemblies received in the slots and engaged by the lateral edges. In yet another aspect, the lighted post may include a side panel, with the side panel having the light transmitting opening.
Accordingly, the lighted post of the present invention is particularly suitable for use as a pathway light or bollard. The lighted post consumes less energy and produces less heat than conventional pathway lights and, further, significantly reduces, if not eliminates, bug or dirt intrusion into the post. These and other objects, advantages, purposes, and features of the invention will become more apparent from the study of the following description taken in conjunction with the drawings.

In the illustrated embodiment, lighted post 10 includes a base 12 and a tubular member 14 that is mounted to base 12 to form a stanchion. It should be understood that the stanchion may be assembled from a variety of other components and further may not require a base. Base 12 is adapted to anchor tubular member 14, for example, to a rigid support surface, such as the ground or to a mat, such as a concrete or asphalt pad or a deck. As best seen in
Base 12 and tubular member 14 are both preferably formed from a strong, rigid material, such as metal, so that lighted post 10 may be used as a bollard. However, it should be understood the base and tubular member may be formed from plastic, such as a reinforced plastic, wood, or a composite material. In addition, in the illustrated embodiment, tubular member 14 comprises a square tubular member; however, as will be described below, the shape of the tubular member, and also of the base, may be varied.

In the illustrated embodiment, each side panel 26 includes a plurality of elongate openings 34 that are arranged in a generally parallel relationship and are aligned generally parallel to the central vertical access of post 10, which form light transmitting openings 30. Outer openings 34a and 34c have shorter vertical dimensions than central opening 34b, though it should be understood that the number size and shape of the openings may be varied.

Each light assembly 28 is formed from a plurality of light sources 40 (
Referring to
Because the outer surfaces (46) of the wave guides (42) are curved, the light emitted from the respective light assembly is fanned outwardly, such as illustrated in
Referring again to
Optionally, the inwardly facing side of panel 26 includes a groove 74 for receiving a seal or gasket, which encircles the respective access opening 22 when panel 26 is secured to tubular member 14 by fasteners 32 to thereby close and substantially seal the interface between panel 26 and tubular member 14 around opening 22. In this manner, light assemblies 28 are mounted in access opening 22 of tubular member 14, with the light emitting surfaces supported such that they are located in openings 34 of panel 26.
Referring to
Accordingly, when assembled, lighted post 10 provides a substantially sealed bollard that is suitable for use as a security bollard or simply as a decorative bollard or for pathway, directional, or signal lighting. Furthermore, the voltage requirements to power the light assemblies within the bollard are relatively low and, therefore, consume less power than conventional lighted bollards. In addition, by incorporating LED light sources into the light assemblies, the heat produced by the light assemblies are significantly reduced over neon, halogen, metal halide, high pressure sodium, fluorescent, and incandescent lights or the like and, further, provide an extended life. For example, high intensity LED's may have a life expectancy on the order of 180,000 hours. Consequently, the light assemblies may be left on for extended periods of time. In addition, given the expected life expectancy of the light assemblies, the bollard may be assembled in a manner so that the light assemblies are permanently mounted or embedded in the tubular member.
As best understood from
Optionally, lighted post 10 may incorporate a sensor that detects, for example, motion or light, for example, a low light condition, which triggers actuation of the light assemblies. For example, housing 80 may house a circuit and/or electronics that are coupled to the sensor and responds to the sensor detecting motion or a low light condition by powering the light assemblies.
Another feature that may be added includes a light shield. For example, a light shield may be mounted to tubular member 14 at of adjacent the upper ends of openings 34 to limit, if not eliminate, “uplighting”. For example, the shield may comprise metal curved shield that is mounted using fasteners 72.
Though illustrated with three panels 26, it should be understood that the tubular member may incorporate one, two, or four panels. In addition, each panel may have a similar configuration to the other panel. Alternately, the tubular member may be provided with different panels and/or light transmitting openings with different configurations. For example, the posts may incorporate light transmitting openings, either in the wall of the tubular member or in the panels, which form signals. For example, the light assemblies and/or light transmitting openings may be configured to form word signals, such as “stop” or “slow” or “caution” or the like, or may be configured to form symbols, such as universal signals.
For example, referring to

As best seen in
It should be understood that the number of openings and size and shape of any of the openings may be varied. Furthermore, each panel may include a combination of different shapes and different size openings.
As noted previously, the shape of the tubular member may be varied. For example, referring to FIGS. 19 and 23-26, lighted post 410 includes a round tubular member 414 that is mounted to a round base 412. In addition, cover 420 comprises a semispherical cover and, further, includes a pair of annular rings 421, which match a pair of annular ribs or rings 423 located adjacent base 412. Tubular member 414 also includes a collar 415 positioned between annular ribs 423 and base 412.
In the illustrated embodiment, side panels 426 are formed from curved plate members 426a, which are formed to match the curvature of tubular member 414. Referring to
Light assemblies 428, which are of similar construction to light assemblies 28, produce less heat than conventional neon lights or similar lights and, therefore, when operated even for a long duration, do not generate a significant amount of heat. Therefore, contact with the light assemblies 428 will not pose any significant risk of injury to a passerby or the like. For further details for light assemblies 428 and the mounting of light assemblies 428, reference is made to the first embodiment. However, it should be understood that the shape of the mounting bracket is preferably adjusted fit the contour of the inner surface of the tubular member 414. Further, separate mounting brackets may be used for each light assembly.
Referring to
Similar to the previous embodiment, the upper end of tubular member 514 is closed by a rounded cover 520. In addition, mounted above and below light assemblies 528 are a pair of upper collars 590 and 592, which are vertically and evenly spaced on either side of the respective light assemblies. Upper collar 592 is provided at the juncture between cover 520 and tubular steel 514 to hide the seam between the cover and the tubular member.
Referring to
Similar to lighted post 410, lighted post 610 includes a plurality of side panels 626, which are formed by curved plates, which are secured to the outer surface of tubular member 614 and, which include a plurality of elongate openings 634 to form light transmitting openings to allow light from light assemblies 628 to be transmitted from tubular member 614. In the illustrated embodiment, lighted post 610 includes four side panel members; however, it can be appreciated that the number of side panels may be increased or decreased as desired. Light assemblies 628 are of similar construction to light assemblies 28; therefore, for further details for light assemblies 628 and the mounting of light assemblies 628, reference is made to the previous embodiments.

The upper open end of tubular member 714 is similarly closed and preferably sealed by a cover 720, which in the illustrated embodiment comprises a flat circular plate, which has an outer diameter generally commensurate in size with the outer diameter of tubular member 714.
Referring to
In the illustrated embodiment, the curved outer surfaces 746 of the respective light assemblies project outwardly from the opening 734. It should be understood, however, that curved outer surfaces 746 may be positioned within the respective openings so that the outer surface is at most flush or sub-flush with the outer surface 746 of tubular member 714.

Lighted post 810C includes a side panel 826C with a plurality of light transmitting opening 834C that form the word “INFO”. In addition, one of the openings may be configured to form a universal symbol, such as an arrow.
In another form, openings 834D of panel 826D of lighted post 810D are configured and arranged to form an alphanumeric identifier, such as a reference to the 2010 Olympics.
Although each of these lighted posts have been illustrated with a single side panel, it should be understood that any of the lighted posts may include two or more side panels. Further, the additional side panels for a given lighted post may be substantially identical to the side panel or may be different. For example, the additional side panel or panels may have different configurations of light transmitting openings to form other words, designs, and/or symbols or may have no light transmitting openings.
In addition, as noted, the light emitting surfaces of the respective light assemblies may be substantially flush, sub-flush, or projecting from the respective openings in the side panels. In some applications, it may be preferable for the light emitting surfaces of the light assemblies to be positioned within the light transmitting openings so that a diffuser, such as a diffuser plate or member may be positioned over the light transmitting openings. Suitable plastic diffuser members could be made from high impact plastics, such as Plexiglas or the like.
Referring to
In the illustrated embodiment, diffuser 27a comprises a diffuser plate that mounts over all the light transmitting openings 30a, which comprise elongated openings 34a similar to openings 34 in the referenced applications. Diffuser 27a is mounted to side panel 26a by a plurality of fasteners 68a that extend through mounting opening 38a and, further, through the light assemblies' mounting bracket 52a wherein fasteners 68a mount both the diffuser and the light assemblies to the side panel.
Referring to
As previously noted, diffuser 27a preferably comprises a plastic member. In addition, diffuser 27a may be tinted either by a coating applied to the diffuser or by incorporating color into the plastic material forming the diffuser.
Alternately, each light transmitting opening may incorporate a diffuser. For example, the light emitting surfaces of the respective light assemblies may be sub-flush with respect to the outer surface of the side panel so that a diffuser element, such as a plastic member, may be positioned in each of the light transmitting openings of the side panels. Optionally, the outer surfaces of the diffusers may be flush with the outer surface of the panel or may project outwardly. The diffusers may be formed with a mechanical attachment means, such as spring tabs or the like, to form, for example, a snap-fit coupling with the side panels. Alternately, the diffusers may be bonded to the panels using adhesive bonding, or in the case of plastic side panels may be welded or molded in place, for example, using insert molding or two-shot molding or the like. Another method of providing the diffusers includes coating the side panels with a suitable plastic to form the diffuser or respective diffusers. For example, the side panels may be formed from two-shot molding or insert molding, with the diffuser extending over the entire side panel or just a portion thereof.

In the illustrated embodiment, lighted post 910 includes a support 914 that is mounted to or in the ground. Alternately, support 914 may be mounted to a support base, including a base plate, a mat, or a deck, such a concrete or asphalt pad or a wooden deck or the like. It should be understood that the manner of mounting the support post may vary depending on its application. For example, the support may be mounted by a base plate or flange, may be “cast in place”, or may be mounted in a receptacle, such as a sleeve to provide a removable light design. For example, support 914 may include an inner post that extends below support 914, which is then inserted into a hole formed in the ground and cast in the hole, for example, by concrete to in effect form a piling for the post. Alternately, a separate tubular member may be cast in the ground to form a sleeve into which support 914 or an inner post is inserted to form a removable post.
Support 914 is preferably formed from a strong, rigid material, such as metal, including aluminum, stainless steel, or iron, so that lighted post 910 may be used as a commercial or residential light. However, it should be understood the support may be formed from plastic, such as a reinforced plastic, wood, or a composite material. In addition, in the illustrated embodiment, support 914 comprises a square tubular member; however, as will be described below, the shape of the tubular member may be varied.
As best seen in
Cover 921 and bracket 922 may be formed from the same material as support 914 or may be formed from a different material. Cover 921 is secured to bracket 922, for example by fasteners 924, such as screws or bolts, or the like, so that cover 921 may be removed from the bracket.
In the illustrated embodiment, cover 921 includes a perimeter base flange 926 and a top 928, which is either formed with or secured to base flange 926 for example by adhesive bonding or welding. Alternately, top 928 and flange may be integrally formed, for example, by molding. In the illustrated embodiment, top 928 comprises a pyramid-shaped member 928a. It should be understood that the shape and size of the top and cover may be varied.
Bracket 922 includes a substantially planar mounting or support flange 930 and a perimeter flange 932 which is either formed with flange 930, or secured thereto for example by welding or adhesive bonding or other suitable fastening methods, and mounts over the upper end of support 914. Flange 930 includes a plurality of mounting openings 930a for receiving bolts or screws for securing bracket 922 to support 914, as will be more fully described below.

Each light assembly 940 is formed from a plurality of light sources 946 (
Referring again to
As best seen in
To assemble the light assembly, light assembly 940 is mounted to bracket 922. Bracket 922 is then mounted on support 914 and secured to member 952 by fasteners 954. Fasteners 950 are then tightened further to contact and bear against support 914. After fasteners 950 are tightened, then cover 921 is placed over bracket 922 and secured to flange 930 by fasteners 924. Once cover 921 is secured to bracket 922, then light transmitting member 944 is inserted into a groove provided in flange 926 of cover 920 and secured to perimeter flange 932 of bracket 922 by fasteners 956 (
Light assembly 940 is powered through wiring 958, which extends from light assembly 940 through a transverse opening 960 provided in flange 930 of bracket 922 into cavity 962 formed by cover 921 and then back down through central openings 964 and 966 provided in flange 930 and member 952, respectively. Alternately, connecting wires may extend from the tubular member through openings 964 and 966 above bracket 922 for coupling to the light assembly or assemblies in space beneath cover 921. Central openings 964 and 966 are at least generally aligned over upper open end 918 of support 914. Support 914 may house a power board, such as a power circuit board with a transformer, that powers the LED and, further, which may include logic circuitry or a controller to provide one or more functions, such as a timer for the light assembly, with the board powered by an external power supply. Alternately, wiring 958 may be extended through support 914 for coupling to an external power supply and optionally external control circuitry.
As noted above, light assembly 940 may be oriented with its light emitting surface facing outwardly or upwardly. In this configuration, a reflective surface or member is preferably provided at the inner surface of cover 921 or at the downwardly facing side of flange of bracket 922 so as to deflect and/or diffuse the light from light assembly 940 in a downward direction and/or in an outward direction from the lighted post. In this manner, the size and light intensity of the puddle of light created by the light assembly may be adjusted as desired. Further, light transmitting member 944 may include one or more optical regions or surfaces for directing light in a desired light pattern, though this is only optional.
In the illustrated embodiment, the light assembly extends around the full perimeter of support 914; however, it should be understood that light assembly 940 may extend around only a portion of the lighted post perimeter or, as noted above, may be provided by a plurality of light assemblies that are either arranged to extend around the full perimeter of the support, a part of the perimeter of the support, or over a discrete portion of the perimeter of the support. However, in the preferred embodiment, the light assembly or assemblies extend around the full perimeter of the support to provide a light emitting surface or surfaces that extend around the full perimeter of the support to generate a line of light around support 914 with a substantially uniform light intensity. It should also be understood that when more than one light assembly is used, the light assemblies may generate the same color light or different color light. For example, one half of the lighted post may be washed with one color light and another half of the light may be washed with a second color of light. It should be understood that the number of light assemblies may be increased to provide even further variations.
Because the outer light emitting surface 948 of the wave guide is curved, the light emitted from the respective light assembly is fanned outwardly, such as illustrated in
Accordingly, when assembled, lighted post 910 is substantially sealed, which reduces if not eliminates bug and dirt intrusion into the lighted post and, when powered, may produce a uniform puddle or pattern of light that is suitable for use as a pathway light. Furthermore, the voltage requirements to power the light assembly or assemblies within the support are relatively low and, therefore, consume less power than conventional pathway lights. In addition, by incorporating LED light sources, the heat produced by the light assembly or assemblies is significantly reduced over neon, halogen, metal halide, high pressure sodium, fluorescent, and incandescent lights or the like, and further, have an extended life. Consequently, the light assemblies may be left on for extended periods of time. In addition, given the expected life expectancy of the light assembly or assemblies, the lighted post may be assembled in a manner so that the light assembly or assemblies are permanently mounted.
As previously noted, the orientation of the light emitting surface or surfaces of the light assembly 940 may be varied. For example, light emitting surface 948 may be oriented to direct the light outwardly toward the inner surface 926a of perimeter wall 926. In which case, the inner surface 926a of perimeter wall 926 of cover 920 may incorporate a reflective member or reflective surface for directing and diffusing the light in a desired direction, for example downwardly or outwardly and downwardly toward support 914. Suitable reflective surfaces include reflective tape, reflective paint, and the like. Suitable reflectors include metal reflectors, such as aluminum reflectors, including polished aluminum reflectors formed from sheets or plates of aluminum that are configured in a shape to achieve the desired light pattern. For example, a parabolic-shaped reflector may be used to provide a defined light pattern. Where light emitting surface 948 is directed upwardly toward the cover, bracket 922 may similarly incorporate a reflective member or surface to achieve the desired light pattern.
As noted previously, the various components forming the structure of lighted post 910 may be formed from a wide variety of materials, including plastic. A suitable plastic may include some percentage of recycled materials, including post consumer recycled (PCR) material, depending on the application. In addition, at least the exterior surfaces of the components may be painted, coated, including powder coated, stained or the like, as desired. For plastic components, the components may be assembled using welding and/or fastening devices, such as screws, bolts, rivets or the like. Notably, all of the structural components comprising the lighted post may be plastic given the low heat output from the light assembly (or light assemblies). In addition, when formed from plastic, the components may be formed, such as by molding, from more than one type of material. For example, any one of the components may be formed from two or more plastics using two-shot molding or the like or may be formed from a composite material and formed, for example, by insert molding. For example, when a reflective surface is desired, the component may be formed by insert molding the reflector into the component.
As would be understood, most lighted posts are configured to prevent “up-lighting”; hence, the covers or at least the brackets (922) are formed to provide a shade and, hence, formed from a non-light transmitting material or at least painted or coated or the like to prevent light transmission. However, in some applications “up-lighting” may be desired, in which case the bracket and cover may be provided with one or more light transmitting portions. For example, bracket 922 and cover 921 may be formed from or include a portion formed from a transparent or translucent material, such as plastic.
Optionally, lighted post 910 may incorporate a sensor that detects, for example, motion or light, for example, a low light condition, which triggers actuation of the light assembly or assemblies. For example, support 914 may house a circuit and/or electronics that are coupled to the sensor and responds to the sensor detecting motion or a low light condition by, for example, powering the light assemblies.

In the illustrated embodiment, top 928A is formed from two top sections 928a, 928b that are joined, for example, by adhesive bonding or welding at a seam 928c. In this application, the fasteners securing the light assembly to the bracket are used to secure the cover assembly to the support. For further details of lighted post 910A, reference is made to lighted post 910.
As noted previously, the shape of the support may be varied. For example, referring to
Bracket 1022 is interconnected with cover 1020 by fasteners that engage a flange or stand-offs formed therein or mounted thereto, similar to the previous embodiment. Similarly, bracket 1022 is secured to member 1052 to thereby secure the cover to the support. For further details of how lighted post 1010 is assembled, reference is made herein to the previous embodiment.

In the illustrated embodiment, cover assembly 1120 includes a cover 1121 that is generally rectangular in shape and includes downwardly depending flanges 1121a, 1121b, 1121c, and 1121d that depend from an upper rectangular member 1121e. Cover 1121 is mounted over the open upper end 1116 of support 1114 and cantilevered therefrom with flange 1121c secured to the side wall 1114a of support 1114 by a fastener 1122, which extends through flange 1121c and into side wall 1114a. Similarly, flanges 1121a and 1121b are secured to the side wall of support 1114 by fasteners 1122 to thereby secure cover 1121 to support 1114.
Positioned in the overhang formed by cover 1121 are light assemblies 1140 which extend between flange 1121d and the side wall 1114d of support 1114 and, further, as previously noted, are enclosed therein by cover 1145. Cover 1145 extends between the opposed flanges 1121a and 1121b and between flange 1121d and side wall 1114a of support 1114. Lens cover 1145 may be adhesively bonded or sealed to the respective flanges of cover 1121 and side wall 1114a of support 1114 or may be mechanically secured thereto, for example, by clips, fasteners, or the like. Further, cover 1145 may incorporate clips or mounting structures therein for securing the lens cover to the support and/or respective flanges of cover 1121.

Similar to the previous embodiments, lighted post 1210 optionally include a transformer 1281 for reducing a supply voltage to a voltage that is suitable for driving the light sources in light assemblies 1228. As described in reference to the previous embodiments, the light sources of light assemblies 1228 may optionally comprise light emitting diodes, including high intensity light emitting diodes, which require less voltage than conventional incandescent lights. Transformer 1281 may be mounted in a housing and, further, may be mounted in tubular member 1214, for example, by a bracket 1282. Bracket 1282 may be mounted in numerous locations in 1214, but in the illustrated embodiment is mounted to coupler 1223 by a tab 1223f (

Transformer 1781 is similarly located in tubular member 1714 and mounted to coupler 1723 by a bracket 1782 which is fastened to an inwardly extending flange or bracket tab 1723c provided on coupler 1723. Again, transformer 1781 is powered by electrical leads 1781a that extend through tubular member 1714 and, further, through base 1712 for coupling to an external power supply as previously noted.
In contrast, lighted post 1810 locates its respective light transmitting openings 1834 in tubular member 1814. Further, cover 1820 includes a top member 1821, which includes a pyramid-shaped portion 1821a and downwardly depending square collar 1821b, which includes mounting openings 1821c for receiving fasteners 1821d for securing cover 1820 to tubular member 1814. For further details of light assemblies 1828 and how they are mounted in tubular member 1814, reference is made to the previous embodiment.

It can be appreciated that the lighted post of the present invention uses less power than heretofore known and yet provides sufficient illumination to be used as a bollard, a pathway light or the like. Further, even when operated or powered for a significant length of time, the lighted post will remain cool to the touch, typically a few degrees over room temperature. In addition, the post are substantially sealed against intrusion from outdoor elements, such as bugs, dirt and water, so that they can maintain their aesthetic appearance. Given the low power consumption, the lighted posts of the present invention can be operated at significant savings. Further, the lighted posts with detachable or removable panels provide greater flexibility and can be quickly and easily changed for venue shifts, for example, by changing or adding different light assembly colors or changing the signage.
While several forms of the invention have been shown and described, other forms will now be apparent to those skilled in the art. Further, features of one embodiment may be incorporated into or substituted for features in another embodiment. As noted, the size and shape of the tubular members, covers, and bases may be varied. In addition, though described as being powered by an external power supply, an internal power supply may also be used. For example, a battery or other voltage supply may be contained in the cover assembly or in the tubular member or collar so that the lighted post may be a powered self-contained unit. Further, many of the members or components forming the lighted posts may be integrally formed with each and, likewise, many of the members may be assembled from separate components. For example, cover 1821 is formed as a unitary member, but it should be understood that portions 1821a and 1821b may be separate components. Therefore, it will be understood that the embodiments shown in the drawings and described above are merely for illustrative purposes, and are not intended to limit the scope of the invention which is defined by the claims which follow as interpreted under the principles of patent law including the doctrine of equivalents.
This application is related to and claims the benefit of provisional applications entitled LIGHTED POST ASSEMBLY, Ser. Nos. 60/631,017; 60/631,132; 60/655,160, filed Nov. 24, 2004; Nov. 26, 2004; and Feb. 22, 2005, respectively, which are herein incorporated by reference in their entireties.
