Abstract

Silicone-containing light fixture optics. A method for manufacturing an optical component may include mixing two precursors of silicone, opening a first gate of an optic forming device, moving the silicone mixture from the extrusion machine into the optic forming device, cooling the silicone mixture as it enters the optic forming device, filling a mold within the optic forming device with the silicone mixture, closing the first gate, and heating the silicone mixture in the mold to at least partially cure the silicone. Alternatively, a method for manufacturing an optical component may include depositing a layer of heat cured silicone optical material to an optical structure, arranging one or more at least partially cured silicone optics on the layer of heat cured silicone optical material, and heating the heat cured silicone optical material to permanently adhere the one or more at least partially cured silicone optics to the optical structure.

First claim

What is claimed is:

1. A linear optic made of silicone and comprising:
an outer surface;
a lower surface in which is defined a cavity adapted to seat over a light source such that a gap exists between the linear optic and the light source; and
a reflector at least partially encapsulated within the silicone and extending between the cavity and the outer surface.

2. The linear optic of claim 1 , further comprising:
a. a first lateral side, an opposing second lateral side, an inner surface, and substantially planar opposing end surfaces;
b. a length defined between the end surfaces;
c. a width defined between the first lateral side and the second lateral side, wherein the width is less than the length; and
d. a cross-sectional shape that is constant along the length.

3. The linear optic of claim 2 , wherein the cross-sectional shape comprises an inconsistent thickness across the width of the linear optic.

4. The linear optic of claim 2 , wherein the length of the linear optic is between 12 inches and 96 inches, inclusive.

5. The linear optic of claim 1 , wherein the silicone is mechanically interlocked with the reflector.

6. The linear optic of claim 5 , wherein the reflector comprises apertures through which the silicone extends to mechanically interlock with the reflector.

7. The linear optic of claim 1 , wherein a portion of the encapsulated reflector extends partially around the cavity.

8. The linear optic of claim 7 , wherein the portion of the encapsulated reflector is located on one of a lateral side of the cavity and extends along a length of the linear optic.

9. The linear optic of claim 7 , wherein the encapsulated reflector comprises a second portion extending laterally from the portion of the encapsulated reflector towards the outer surface of the linear optic, the second portion comprising a mounting flange extending outside the outer surface of the linear optic.

10. The linear optic of claim 1 , wherein the encapsulated reflector comprises a first reflector and a second reflector located on opposite lateral sides of the cavity.

11. The linear optic of claim 10 , wherein each of the first reflector and the second reflector comprises a first angular portion extending away from the cavity, and a second portion extending laterally from the first portion towards the outer surface of the linear optic, the second portion comprising a mounting flange extending outside the outer surface of the linear optic.

12. The linear optic of claim 1 , wherein the reflector extends entirely above the lower surface.
