Abstract

An optic assembly includes a light source, a reflector to reflect light emitted by the light source, and an optical lens disposed over and/or around the light source. The optical lens is configured to direct light emitted from the light source using refraction and total internal reflection.

Claims

1. An optic assembly comprising:

a light source;

a reflector to reflect light emitted by the light source; and

an optical lens disposed over and/or around the light source;

wherein the optical lens is configured to direct light emitted from the light source using refraction and total internal reflection.

2. The optic assembly of claim 1, wherein reflector and optical lens are configured to define a cavity between the reflector and the optical lens.

3. The optic assembly of claim 2, wherein a boundary of the cavity includes a total internal reflective surface.

4. The optic assembly of claim 2, wherein the reflector is bonded to the optical lens by means of a sonic weld.

5. The optic assembly of claim 3, wherein the cavity is sealed and provides for self heating to clean off any residue on the total internal reflective surface.

6. The optic assembly of claim 1, wherein the light source is an LED.

8. The optic assembly of claim 1, wherein the optical lens is recessed within a housing and light emitted from the light source is reflected off the housing to light an area proximate the lighting assembly.

9. The optic assembly of claim 1, wherein light emitted from the light source is directed substantially perpendicular to a normal of a base upon which the light source rests.

10. The optic assembly of claim 1, wherein the light source is an LED.

11. The optic assembly of claim 1, wherein the optical lens defines a cavity between the light source and the optical lens.

7. An optic assembly comprising:

a light source; and

,

an optical lens disposed over and/or around the light source, wherein the optical lens is disposed exclusively within the visibility envelope, wherein the optical lens is fashioned to control light emitted from the light source using refraction and total internal reflection.

12. An optic assembly comprising:

a light source;

a reflector to reflect light emitted by the light source; and

an optical lens disposed over and/or around the light source, wherein the optical lens is disposed to refract a first portion of the light emitted from the light source immediately through a first surface and totally reflect a second portion of light source emitted from the light source immediately off a second surface.

13. The optic assembly of claim 12, wherein after totally reflecting off the second surface, the second portion of light refracts through the first surface.

14. The optic assembly of claim 12, wherein the first surface is the optical lens.

15. The optic assembly of claim 12, wherein the second surface is a total internal reflective surface.

16. The optic assembly of claim 12, wherein reflector and optical lens are configured to define a cavity between the reflector and the optical lens.

17. The optic assembly of claim 16, wherein a boundary of the cavity includes a total internal reflective surface.

18. The optic assembly of claim 16, wherein the reflector is bonded to the optical lens by means of a sonic weld.

19. The optic assembly of claim 16, wherein the cavity is sealed and provides for self heating to clean off any residue on the total internal reflective surface.

20. The optic assembly of claim 12, wherein the light source is an LED.
