Patent Grant
11604309
The present disclosure relates generally to a lighting device. More specifically, the disclosure is directed to a fiber-optic lighting device.
Tinsel garlands are generally used for decoration during the Holidays. The garlands have reflective surfaces that, in daylight, make the tinsel visually sparkling to a viewer, and adds to the festiveness of the decoration during the Holidays.
Attempts have been made to illuminate the tinsel garlands at night. For example, a string of small incandescent light bulbs may be wound around the tinsel garland, so that light from the light bulbs may reflect off of the tinsel garland so that it can be seen at night.
However, the tinsel garland itself does not illuminate any light, but must rely on lights reflected off of its surface. Also, the small light bulbs wound around the tinsel garland have a tendency to burn out quickly. Where simple circuits are used, the burning out of even one light bulb means that the entire illumination goes out, and the entire tinsel garland has to be replaced. It is also tedious to identify the particular burned out light bulb. Therefore, reliability is an issue.
Further, even when parallel circuits are used for the light bulbs so that one burned out light bulb does not affect the entire illumination, the design adds to the complexity of the device, and the use of numerous light bulbs for the tinsel garland to consume large amounts of electricity over time.
Recently, Light Emitting Diodes (LED) have replaced the use of light bulbs, resulting in a prolonged lifespan of the illumination. The same problems can persist when an LED goes out. That is, when one LED burns out, the entire illumination has to be replaced period where simple circuits are used.
Additionally, when multiplicity of LED lights are still used in the illumination the device becomes more complicated and renders the illumination uneven according to the lifetime of each LED, which tends to variably dim at different times. Also, amount of energy consumption by multiple LEDs are still too high.
In view of the above discussion, there is a need for a different type of illumination for the tinsel garland that would overcome the deficiencies noted above.
A summary of several example embodiments of the disclosure follows. This summary is provided for the convenience of the reader to provide a basic understanding of such embodiments and does not wholly define the breadth of the disclosure. This summary is not an extensive overview of all contemplated embodiments, and is intended to neither identify key or critical elements of all embodiments nor to delineate the scope of any or all aspects. Its sole purpose is to present some concepts of one or more embodiments in a simplified form as a prelude to the more detailed description that is presented later. For convenience, the term “some embodiments” or “certain embodiments” may be used herein to refer to a single embodiment or multiple embodiments of the disclosure.
Certain embodiments disclosed herein include an illumination device, including a fiber optic spiral wrapped around an electrical wire, a plug connected to the electrical wire on one end, and a fiber optic bundle connected to the fiber optic spiral and the electrical wire on an other end opposite the one end. The fiber optic bundle includes a bundle chamber attached to the electrical wire and the fiber optic spiral on a first end, and an illumination member at the wide end and attached to the electrical wire, and fiber optic strands extending from a second end opposite the first end.
The subject matter disclosed herein is particularly pointed out and distinctly claimed in the claims at the conclusion of the specification. The foregoing and other objects, features, and advantages of the disclosed embodiments will be apparent from the following detailed description taken in conjunction with the accompanying drawings.
It is important to note that the embodiments disclosed herein are only examples of the many advantageous uses of the innovative teachings herein. In general, statements made in the specification of the present application do not necessarily limit any of the various claimed embodiments. Moreover, some statements may apply to some inventive features but not to others. In general, unless otherwise indicated, singular elements may be in plural and vice versa with no loss of generality. In the drawings, like numerals refer to like parts through several views.
The various disclosed embodiments include a fiber optic tinsel garland that adds illumination and decoration to a natural or artificial Christmas tree. This allows the observer the opportunity to appreciate the beauty of a brightly illuminated tree that fiber optic light decorations offer. The fiber optic tinsel garland has an electrical power source connected to it, and includes an electrical wire with a fiber optic strand wound around the electrical and attached to a power source. The fiber optic garland may be around 35 feet in length, and in place of short, side-flaring tinsel strands, and includes flaring fiber strands that illuminate with “moving” light and colors.
The fiber optic tinsel garland may be wrapped or spun around a Christmas tree, hung over doorways or mounted to adorn a drape line along walls or ceilings for bright fiber optic decoration.
The fiber optic spiral 110 wraps tightly around an electrical wire 120, and is made of plastic or glass fibers. In an embodiment, the fiber optic spiral 110 may illuminate with sequential lighting and may also alternate colors during illumination.
The electrical wire 120 is connected to the plug 130 on one end. In an embodiment, the plug 130 is connected to a power source such as a wall-mounted electrical outlet. Alternatively, the plug 130 may also be connected to a battery.
A fiber optic bundle 140 (bundle) is attached to an end of the electrical wire 120 opposite to the end of the electrical wire 120 where the plug 130 is located.
Further details of the fiber optic bundle 140 will be described in more detail in
In the embodiment, the garland 100 is wrapped around a Christmas tree. However, this example is not exclusive, as the garland 100 can also be hung on different structures, such as off a ceiling, on a door, or on the side of a building for decorative purposes. Also, the plug 130 does not necessarily have to be on an end of the electrical wire 120 opposite to that of the bundle 140. For example, both the plug 130 and the bundle 140 can be located on the same end of the electrical wire 120. Also, the number of both the plug 130 and the bundle 140 attached to the electrical wire 120 can vary. For example, there may be multiple plugs 130 or bundles 140 located along the electrical wire 120. Here, any of the plugs 130 may be connected to other garlands 100, and additional bundles 140 may run throughout the electrical wire 120 to add additional illumination and attractiveness to the user.
In operation, power from an outlet is delivered from the plug 130 at the electrical outlet through the electrical wire 120 to the bundle 140, where the power is split to illuminate both the bundle 140 and the fiber optic spiral 110.
The bundle chambers 220 are connected circumferentially surrounding the core 210, at a wide end 222 of each of the bundle chambers 220. In the embodiment, the bundle chambers 220 may have a conical, tapered shape, each have a narrow end 224 opposite the wide end 222. Here, the fiber optic strands 230 extend from the narrow ends 222 of the bundle chambers 220. The bundle chambers 220 each include a light source (not shown), the details of which will be described in more detail in
The fiber optic strands 230 may be made of plastic or glass fibers that gather around the narrow end 224 of the bundle chambers 220. In the embodiment, the number of fiber optic strands 230 within each bundle chamber 220 can vary in order to achieve the desired lighting effect and optimize illumination of the garland. Also, the fiber optic strands 230 may have similar diameters, and may be made of similar materials as that of the spiral 110. However, in another embodiment, the diameter and materials may vary between the fiber optic strands 230 and the spiral 110.
The LED 310 is a lighting component that is seated above the substrate 320. Both the LED 310 and the substrate 320 may be located on a platform 330. In this embodiment, the bundle chamber 220 has circular conical shape, with a wider end having a maximum diameter of about 8 mm or less and an inner diameter of about 6 mm or less facing the LED 310 to direct light from the LED 310 to funnel through the bundle chamber 220. The bundle chamber 220 also has a narrower end opposite the wider end, where the fiber-optic strands 230 extends from the narrower end. The bundle chamber 220 may also be about 8 mm or less in height. The height profile has been found to be optimal in reducing the bundle chamber's 220 visibility. Also, the dimensions given above allows for an observer's visual focus on the fiber optic bundle strands 230.
That is, in the embodiment, the size of the bundle chambers 220 may be small relative to fiber optic strands 230, so that the fiber optic bundle can have a more tinsel-like appearance. Also, in the embodiment, the LED 310 fits snuggly just above the reflector rim 340 at a lower center portion of the reflector rim 340, which may be conical in shape in an inverse configuration to the bundle chamber 220. Beneath the LED 310 and the platform 330, the conical conduction housing 350 houses the electrical wiring (not shown). The electrical wiring housed in the conical conduction housing 350 allows the LED 310 to receive power via the electrical wire 120. The conical conduction housing 350 is non-transparent, and allows no light penetration from the light emanating from the LED 310. This way, light from the LED is focused in a vertical direction towards the fiber-optic strands, along with the upward-focused reflection allowed by the mirrored reflector rim 340. The electrical wire 120 carries the electrical power current to the LED 310 via these connections.
In another embodiment, the garland 100 as a unit would include many of these small bundle chambers 220 along with the accompanying fiber-optic strands 230 ordered very closely in a spiral order encircling the electrical wire 120 along the length of the garland 100.
In an embodiment, to simplify the structure, the inside of the bundle chamber 220 may be hollow without the reflector rim 340 for the light emitted from the LED 310 to directly pass through to the fiber-optic strands 230. Here the interior of the bundle chamber 220 may itself be reflective to amplify and direct the light emitted from the LED 310 toward the fiber-optic strands 230.
In another embodiment, the entire bundle chamber 220 may be constructed of solid to translucent plastic (i.e., have a translucent core) that encapsulates the LED 310 and restricts light penetration and exit. Here, light is permitted to exit through the opening at the open top area of the bundle chamber 220 to illuminate the small bundle of tightly packed fiber optic strands 230.
Additionally, a small laser lighting including laser diodes may serve as a light source in place of the LED 310 to illuminate the fiber-optic strands 230. Also, the fiber optics strands 230 include short length fiber optic fibers of about under 4 inches in length, which is preferable for maximum light transfer through the fibers to achieve maximum illumination, while simultaneously achieving minimum light wattage needed to illuminate the fiber optics strands 230 to a certain lumen level from the LED 310. The fiber optics strands 230 also include fine individual optic fibers that emit light from both the ends and the sides of each fiber. To offer maximum illumination and brightness from all sides the fiber optics strands 230 are clustered together.
The cylindrical fiber optic bundle chamber 410, which may be constructed of plastic, has an outer diameter of about 8 mm or less, an inner diameter of about 6 mm or less, and a height of about 8 mm or less. The height profile has been found to be optimal in reducing the cylindrical fiber optic bundle chamber's 410 visibility. Also, the dimensions given above allows for an observer's visual focus on the fiber optic bundle strands 230.
That is, in the embodiment, the size of the bundle chambers 410 may be small relative to fiber optic strands 230, so that the fiber optic bundle can have a more tinsel-like appearance.
The color pattern disc 440 may be a semi-transparent/translucent plastic disc that is located above the cylindrical fiber optic bundle chamber 410, with varied color patterns. In an embodiment, the color pattern disk 440 may be configured to turn and rotate around its central axis so that the light coming from the LED 310 maybe filtered into different colors as it passes through the color pattern disk 440 to the fiber optic strands 230.
The axle 450 is substantially vertically connected to the color pattern disc for 440 on one end. On another opposite end the axle 450 is connected to the electric motor 460. The electric motor 460, which is connected to and powered by the electrical wire 120, turns the color pattern disc 450 in a circular manner.
In operation, light coming from the LED 310, which may be directed vertically by the reflector rim 340 away from the LED 310, passes through the rotating color pattern disc 440 to the fiber optic strands 230. This creates a “moving colors” effect, where the lights emitted from the LED 310 changes colors when emanating from the fiber optic strands 230. In an embodiment, while the color pattern disc 440 rotates around its center axis, it can also be configured to move along the outer rim of the upper part of the cylindrical fiber optic bundle chamber 410. For example, the electric motor 460 may move above the platform 420 around the outer periphery of the inside of the cylindrical fiber optic bundle chamber 410, bringing along with the axle 450 and the color pattern disc 440 with it. This way, the color pattern disc 440 also moves around the upper outer periphery of the cylindrical fiber optic bundle chamber 410.
