Abstract

A light fixture housing contains an LED light source. A continuous light diffuser having a main body portion is defined between a first surface and a second surface of the continuous light diffuser, and is positioned within the housing to fully cover a light emitting opening formed in the housing. A discontinuous light diffuser having a main body portion is defined between a first surface and a second surface of the discontinuous light diffuser. A plurality of openings pass from the first surface of the discontinuous light diffuser through the main body portion to the second surface of the discontinuous light diffuser. The discontinuous light diffuser is positioned with its body portion in adjacent relation to either one of the first surface and the second surface of the continuous light diffuser so as to occlude a portion of the light emitting opening.

Claims

1. In combination:

a ceiling light fixture housing defining a light emitting opening and a first housing axis and a second housing axis transverse one to the other;

a continuous light diffuser having a main body portion defined between a first surface and a second surface of said continuous light diffuser, said continuous light diffuser positioned within the ceiling light fixture housing to fully cover said light emitting opening formed in the ceiling light fixture housing;

a discontinuous light diffuser having a main body portion defined between a first surface and a second surface of said discontinuous light diffuser, said main body portion having a major axis and a minor axis transverse one to the other; and

,

a plurality of openings passing from said first surface of said discontinuous light diffuser through said main body portion to said second surface of said discontinuous light diffuser;

wherein said discontinuous light diffuser is positioned with its body portion in adjacent relation to either one of said first surface and said second surface of the continuous light diffuser so as to occlude a portion of said light emitting opening.

2. The combination according to claim 1, wherein the main body portion of said continuous light diffuser is generally planar.

3. The combination according to claim 2, wherein said first surface of said main body portion of said discontinuous light diffuser is generally planar.

4. The combination according to claim 3, wherein said second surface of said main body portion of said discontinuous light diffuser is generally planar.

5. The combination according to claim 4, wherein said first surface and said second surface of said main body portion of said discontinuous light diffuser are substantially parallel one to the other.

6. The combination according to claim 5, wherein the portion of said light emitting opening occluded by said discontinuous light diffuser is partial.

7. The combination according to claim 1, wherein said plurality of openings in said discontinuous light diffuser forms a pattern.

8. The combination according to claim 7, wherein said plurality of openings in said discontinuous light diffuser forms a regular pattern.

9. The combination according to claim 8, wherein said plurality of openings in said discontinuous light diffuser forms an array.

10. The combination according to claim 9, wherein said plurality of openings in said discontinuous light diffuser forms a regular array of circular openings.

11. The combination according to claim 10, wherein said regular array of circular openings comprises alternating rows of circular openings having a first size and circular openings having a second size.

12. The combination according to claim 1, wherein said plurality of openings in said discontinuous light diffuser forms at least one of symbols and letters and numbers.

13. The combination according to claim 12, wherein said symbols and letters and numbers form a commercial message.

14. The combination according to claim 1, wherein said plurality of openings in said discontinuous light diffuser forms a decorative pattern.

15. The combination according to claim 1, wherein said plurality of openings in said discontinuous light diffuser forms seasonal shapes or figures.

16. The combination according to claim 1, wherein the first housing axis of the ceiling light fixture housing and the major axis of the discontinuous light diffuser are parallel one to the other and the second housing axis of the ceiling light fixture housing and the minor axis of the discontinuous light diffuser are parallel one to the other.

17. The combination according to claim 16, wherein said ceiling light fixture housing is longer along said first axis and shorter along said second axis and said discontinuous light diffuser is longer along said major axis and shorter along said minor axis.

18. The combination according to claim 17, wherein the shape of the discontinuous light diffuser is rectangular.

19. The combination according to claim 1, wherein the discontinuous light diffuser is positioned with its second surface in contacting relation with the first surface of the continuous light diffuser.

20. The combination according to claim 1, wherein the discontinuous light diffuser is positioned with its first surface in contacting relation with the second surface of the continuous light diffuser.

21. The combination according to claim 20, further comprising supplemental means for attaching the discontinuous light diffuser in contacting relation with the continuous light diffuser.

22. The combination according to claim 21, wherein the supplemental means for attaching the discontinuous light diffuser in contacting relation with the continuous light diffuser comprises a supplemental light diffuser.

23. The combination according to claim 22, wherein the supplemental light diffuser is optically clear.

24. The combination according to claim 1, wherein the main body portion of each of the continuous light diffuser and the discontinuous light diffuser is curved.

25. The combination according to claim 1, wherein the main body portion of each of the continuous light diffuser and the discontinuous light diffuser is curved to the same shape one as the other.
