DETAILED DESCRIPTION OF THE INVENTION

[0037] Referring now to the drawings which depict different embodiments consistent with the present invention, wherever possible, the same reference numbers will be used throughout the drawings and the following description to refer to the same or like parts.

[0038] FIG. 1A depicts a perspective view of an acoustic luminaire. The acoustic luminaire 100 includes a light reflector 102 positioned in a central portion of the acoustic luminaire 100. FIG. 1B depicts a cut away view of the acoustic luminaire 100. The luminaire 100 includes acoustic material 104 separated by the light reflector 102. Light emitting devices 108 and 110 are positioned on a surface of the acoustic material facing the light reflector 102, which is contained within a parabolic cover 106. A securing unit 112 attaches to the parabolic cover 106 to attach the acoustic luminaire 100 to a structure. FIG. 1C depicts a bottom view of the luminaire 100 showing the light reflector 102 positioned along a centerline of the luminaire 100 with the light reflector 102 being separated from the edges of the luminaire by acoustic material.

[0039] FIG. 2A depicts a perspective view of an acoustic luminaire 200. The acoustic luminaire includes a light cover 202. FIG. 2B depicts a side view of the luminaire 200. A support unit 204 extends across a diameter of the luminaire 100 connecting two opposite sides of the luminaire 200. FIG. 2C depicts a second side view of the luminaire 200 showing the curvature of the luminaire 200 and light cover 202. FIG. 2D depicts a cut away view of the luminaire 200. The luminaire 200 includes a strip of light emitting devices 206 positioned on a side of the support unit 204 facing the luminaire 200. The base of the luminaire 200 includes acoustic material 208 and the light cover 202. The light emitting devices 206 are arranged such that light shines through the lens 208.

[0040] FIG. 3A depicts a perspective view of an acoustic luminaire 300. The luminaire 300 includes a lens 302. FIG. 3B depicts a cut away view of the luminaire 300. The luminaire 300 includes acoustic material 304 that surrounds the edges of the lens 302. A light emitting device 306 is positioned along the length of the lens 302. A cover unit 308 is secured to an end of the luminaire 300 opposite the lens 302. FIG. 3C depicts a top view of the luminaire 300. The cover unit 308 is secured to the edge 310 of the luminaire 300 by securing units 312. In one embodiment, the securing units 310 are movable to allow the cover unit 308 to be removed. FIG. 3D depicts a bottom view of the luminaire 300. The lens 302 includes a plurality of extension units 314 that are each separated by an angle Ω. In one embodiment, the angle Ω is the same value. In another embodiment, the angle Ω is one hundred and twenty degrees. In another embodiment, the angle between each extension 314 is different.

[0041] FIG. 4 depicts a process of manufacture a luminaire. In step 402, a flat layout pattern is cut form a piece of material. The pattern is sized such that the material can shrink and stretch. In one embodiment, the material is an acoustic dampening material. In step 404, heat is applied to the material. In one embodiment, heat is applied to the top and bottom of the material. In another embodiment, heat is applied to the top or the bottom of the material. The temperature of the heat applied ranges from 285° F. to 325° F. and is based on the size and shape of the material. In step 406, after a predetermined time of heating, the material is placed into a compression mold. The predetermined time is based on the size and shape of the material. In one embodiment the predetermined time is between 7 and 10 minutes. The material is allowed to cool while being in the compression mold. In step 408, the material is removed from the mold.

[0042] While various embodiments of the present invention have been described, it will be apparent to those of skill in the art that many more embodiments and implementations are possible that are within the scope of this invention. Accordingly, the present invention is not to be restricted except in light of the attached claims and their equivalents.
