The claimed subject matter relates to home furnishings and equipment, and more specifically relates to lighting fixtures.
The following background information presents examples of specific aspects of the prior art (e.g., without limitation, approaches, facts, or common wisdom) that, while expected to be helpful to further educate the reader as to additional aspects of the prior art, is not to be construed as limiting the claimed embodiments, or any embodiments thereof, to anything stated or implied therein or inferred thereupon.
A lighting fixture, or luminaire, is an electrical device containing an electric lamp that provides illumination. Lighting fixtures have a fixture body and one or more lamps. In the case of light-emitting diode (LED) fixtures, the lamps are hard-wired in place. Typically, lighting extrusions are materials that are formed to produce a specific cross-sectional profile for a lighting fixture. Such extrusions can be created specifically to fit the desired shape of the light and enable a designer to easily place lights exactly where they are required without the need for larger, more obtrusive, traditional light fixtures.
Lighting extrusions are elongated pieces of material with a consistent cross-sectional profile. In many instances, these are elongated aluminum extrusions with a space for holding LED lights that span the length of the troffer. Troffers may be mounted to or suspended from ceilings, walls, floors, etc. In many cases, the extrusions are recessed into the ceiling, with the back side of the extrusion protruding into the ceiling.
When an LED lighting fixture with a unique or customized shape is desired, lighting extrusions are not often used, due to the difficulty involved in working a metal extrusion into a desired shape. Currently to create such luminaires, all items must be custom manufactured, cut, welded etc. per each specific luminaire. Therefore, even though lighting fixture aluminum extrusions meet some of the needs of the market, the above-noted drawbacks lessen the usability and user-friendliness of the existing devices in unique or custom applications. Current lighting fixture aluminum extrusions do not provide a convenient means of integrating linear LED strip lights into an LED lighting fixture that is customized in shape.
As a result of the previously recognized issues, a need exists for more efficient methods and systems for providing LED lighting fixtures using extrusions that may be customized in shape.
Illustrative embodiments of the disclosure are generally directed to an LED lighting fixture system using aluminum extrusions. The LED lighting fixture system provides a shape customizable lighting fixture. The system comprises a planar opaque top element and an opposing planar translucent bottom element that can be custom fabricated to take any number of shapes. Upon fabrication of the top and bottom elements into a custom shape, for example, a first aluminum extrusion is fitted to the left side, and a second aluminum extrusion is fitted to the left side. The first and second extrusions adapt to the shapes of the top and bottom elements. The extrusions comprise a first channel on the interior surface configured to accept the top element, and a second channel configured to accept the bottom element. A first end cap couples to a first end of the first and second extrusions. A second end cap couples to a second end of the first and second extrusions. An LED strip is operational on an interior surface of the top element.
Additional aspects of the claimed subject matter will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the claimed subject matter. The aspects of the claimed subject matter will be realized and attained by means of the elements and combinations particularly pointed out in the appended claims.

An LED lighting fixture system 100 using aluminum extrusions is referenced in
Working in conjunction with the top and bottom elements 102, 104 are a first and second aluminum extrusion 106, 108. The extrusions 106, 108 couple to opposing left and right sides of the top and bottom elements 102, 104. Thus, the extrusions 106, 108, with corresponding first and second end caps 110, 112, form a lighting fixture enclosure. Such an enclosure creates an elegant and convenient means of integrating linear LED strip lights in a protected and concealed rigid aluminum housing.
The first and second extrusions 106, 108 may be composed of a metal, such as aluminum, that enable the extrusions 106, 108 to conform to the shape of the top and bottom elements 102, 104 when it is bent in the appropriate way to conform to that shape. Alternatively, the first and second extrusions 106, 108 may be composed of material, such as rubber or another polymer, that enable the extrusions 106, 108 to more easily conform to the shape of the top and bottom elements 102, 104. This adaptable structure enables the system 100 to be placed in variously sized and shaped light fixture receptacles requiring illumination.
As shown in
In one possible embodiment, the planar opaque top element 102 has an irregular circumferential shape. Thus, the circumference of the curved geometric top element 102 is not linear or a simple geometry, such as a circle or square. Rather, irregular shapes, such as a wave, an S-shape, or a multi-curved shape may be used. Thus, the irregular circumferential shape of the first extrusion 106 defines a particular irregular shape, such as an S-shape (see
Opposing the top element 102 is a planar translucent bottom element 104. The bottom element 104 has a translucent configuration that enables passage of light from the LED strip 210 held on the interior. Various color filters can be applied to the bottom element 104 to enable the LED strip 210 to emit different colors and patterns through the bottom element 104. In one possible embodiment, the translucent bottom element 104 comprises a plastic material.
In some embodiments, the bottom element 104 has an identical circumferential shape to the circumferential shape of the top element 102. Thus, if the top element 102 is wave-shaped, the bottom element 104 has an identical wave shape. It is significant to note that both the top and bottom elements 102, 104 are customizable. In this manner, any number of shapes and sizes for the top and bottom elements 102, 104 may be used to accommodate different buildings, ceilings, and other light fixture frameworks.

In one non-limiting embodiment, the first extrusion 106 comprises an aluminum material. The aluminum material enables greater flexibility to the first extrusion 106, so as to conform to the top and bottom elements 102, 104, as described below. However, other malleable or flexible materials may also be used. In some embodiments, the first extrusion 106 adapts to the shapes of the planar opaque top element 102 and the planar translucent bottom element 104, which may include a color. This adaptation to the shapes can be through simply bending the aluminum metal manually, or with a bending tool known in the art of metal working.
In yet another example of the first extrusion 106 conforming to the irregular shapes of the top and bottom elements 102, 104, a precast mold of the first extrusion 106 that matches the shapes and sizes of the top and bottom elements 102, 104 can be used. Once the mold is filled with a fluid material, the first extrusion 106 has the same dimensions as the top and bottom elements 102, 104. In this manner, it is advantageous to fabricate the first extrusion 106 from aluminum, or other pliable materials known in the art of light fixtures. Additionally, anodized aluminum may also be used to fabricate the extrusions.
In some embodiments, the first extrusion 106 comprises a first channel 114 on its interior surface 206. The first channel 114 may include a ridge that forms a snap-fit relationship with correlating ridges in the top and bottom elements 102, 104. In one non-limiting embodiment, the first channel 114 is configured to accept the top element 102. Similarly, the first extrusion 106 comprises a second channel 202 on its interior surface, 206 below the first channel 114, the second channel is configured to accept the bottom element 104. This allows the first extrusion 106 to couple to the top and bottom elements 102, 104 after adapting to their shapes and sizes. As illustrated, both the first and second channel 114, 202 run parallel to each other. The channels may be simple linear channels, or more intricate channels with flanges, ridges, depressions, and other ornamental and heat dissipating shapes.
In some embodiments, the channels 114, 202 may form flanges, right angles, and depressions to enable a sliding, lockable relationship with the top and bottom elements. Such irregularly shaped channels (see
As referenced in
In some embodiments, the second extrusion 108 comprises a first channel 116 on an interior surface 208. The first channel 116 may include a ridge that forms a snap-fit relationship with correlating ridges in the top and bottom elements 102, 104. In one non-limiting embodiment, the first channel 116 is configured to accept the top element 102. The second extrusion 108 may also include a second channel 204 that extends along the interior surface 208, below the first channel 116. The second channel 204 is configured to couple to the bottom element 104. As illustrated, both the first and second channels 116, 204 run parallel to each other.
As discussed above, the first and second extrusions 106, 108 detachably couple to the top and bottom elements 102, 104, forming an at least partially enclosed lighting fixture. Various fastening means may be used enable coupling in such a manner. In one possible embodiment, the first and second extrusions 106, 108 form multiple fastening holes 208a, 208n that are sized and dimensioned to enable passage of at least one fastener. The fastening holes 208a, 208n are configured to enable connectivity between the extrusions to the top and bottom elements 102, 104, and the end caps, discussed below. The fasteners 118a-d may include, without limitation, a clip, a threaded screw, a bolt, a nail, a magnet, an adhesive, and a mechanical snap-fit means.
Looking again at
In some embodiments, the first and second caps 110, 112 are substantially similar, having a flat, square or rectangular shape. The end caps 110, 112 are configured to form multiple fastening holes. The fastening holes are configured to enable connectivity between the end caps 110, 112 to the extrusions 106, 108 and top and bottom elements 102, 104. In one non-limiting embodiment, the fastening holes are sized and dimensioned to enable passage of the at least one fastener 118a-d.
In one possible embodiment of the system 100, multiple corner brackets 200a, 200b, 200c, 200d couple to the ends 120a-b, 122a-b in order to strengthen the connection between the elements 102, 104 and the extrusions 106, 108. The corner brackets 200a-d are configured to help fasten the first and second end caps 110, 112 to the first end 120a-b of the first and second extrusions 106, 108 and the second end 122a-b of the first and second extrusions 106, 108, respectively. However, in alternative embodiments, no corner brackets are used; and rather, the elements 102, 104 and the extrusions 106, 108 directly attach to each other and the end caps 110, 112.
In some embodiments, a fastening tool (not shown) may be utilized to introduce the at least one fastener 118a-d into the fastening holes 208a, 208b. The fastening tool may include, without limitation, a screwdriver, an Allen wrench, a torque screw, and other fastening means known in the art. The fastening tool rotatably drives the fastener into the side of the first and second extrusions 108 and/or the top and bottom elements 102, 104.
To enable illumination from the system 100, an LED strip 210 is placed on an interior surface of the planar opaque top element 102. The LED strip 210 may extend across the longitudinal of the top element 102. The LED strip 210 can fasten to the top element 102 through a snap fit relationship, or fasteners, or a magnetic connection. In other embodiments, the LED strip 210 may be a flexible strip of light, having any number of colors, lighting patterns, watts, and other variables known in the art of lighting.
In some embodiments, the system 100 may also provide a circuitry that is operatively connected to the LED strip 210. The circuitry provides sufficient electrical power to achieve lighting in the LED strip 210. In some embodiments, the circuitry regulates power to the LED strip 210, so as to prevent power outages, static electricity, or electrical harm during operation or maintenance of the system 100. In one non-limiting embodiment, the circuitry includes wiring, resistors, circuits, and other electronic components known in the art of lighting fixtures.
As discussed above, the first and second extrusions adapt to the shape of the top and bottom elements 102, 104. While a wave shape has been discussed above, other shapes and dimensions may also be used. As shown in
And similar to the wave-shaped extrusion, the first extrusion couples to both the top and bottom elements 102, 104 while on the left side. In additional embodiments, the second extrusion 500 couples to the opposite right side, while also adapting to the rectangular shape of the top and bottom elements. In some embodiments, the first extrusion 300 includes an exterior side 302 that is flat.
In operation, the top and bottom elements are molded into a desired irregular circumference shape. This may include a wavelike shape, as illustrated in
After the top and bottom elements are in their final shape, and the LED strip attached for operation, a first extrusion and a second extrusion are shaped to be similar to the top and bottom elements. The extrusions are then coupled to the left and right side of the elements, so as to form an enclosure. Channels on the extrusions enable facilitated connectivity, therebetween. End caps may also be applied to the termini of the elements and extrusions. Various fasteners can be driven through fastening holes in the extrusions to secure the top and bottom elements and end caps to enable efficient and ornamental illumination from the LED strip.
In one embodiment, the section of first extrusion 300 and second extrusion 500 shown in
The corner brackets 200a, 200b, 200c, 200d will now be described with reference to
The corner piece also includes an elongated flange 2002, located at the center of the corner piece, extending perpendicular to the shaft and parallel to the flange 2001, the flange 2002 also shaped and sized to fit securely within the channel 311b of the end cap 110. The corner piece also includes an elongated flange 2003, located at the center of the corner piece, extending perpendicular to the shaft and parallel to the flange 2005, the flange 2003 also shaped and sized to fit securely within the channel 311b of the first extrusion 106.
In this way, the corner piece can be used to connect the end cap 110 to the first extrusion 106. Due to the congruence of the first and second extrusions, and the end caps 110, 112, the corner piece can also be used to connect the end cap 110 to the second extrusion 108, to connect the end cap 112 to the second extrusion 108, and to connect the end cap 112 to the first extrusion 106.
The fasteners 118a-d will now be described with reference to
The fastener also includes a flange 1181, located at the proximal end, extending away from the fastener, the flange 1181 also shaped and sized to fit securely within the channels 311a, 331c, or 304b of the first extrusion, second extrusion or end caps 110, 112. The fastener is configured so as to attach to a channel on the interior surface of the extrusion, such as at or near the channel 116 on an interior surface 208 of the second extrusion 108, as shown in
