Cyc attachment for a light engine
View Patent ↗A luminaire including a light engine having a light source and a housing and a light-diffusing attachment that includes a frame secured to the housing of the light engine, a refracting lens supported by the frame, and a diffuser supported by the frame.
1. A light-diffusing attachment for a light engine having a housing, comprising:
a frame adapted to be secured to the housing of the light engine;
a refracting lens supported by the frame; and
a diffuser supported by the frame,
wherein the refracting lens comprises a lenticular lens,
wherein the lenticular lens includes a first array with a first orientation and a second array with a second orientation different than the first orientation.
2. A light-diffusing attachment as claimed in claim 1 , further comprising a folding mirror supported by the frame that directs light from the light engine to the refracting lens and the diffuser.
3. A light-diffusing attachment as claimed in claim 2 , wherein the folding mirror includes an array of stepped mirrors.
4. A light-diffusing attachment as claimed in claim 1 , wherein the lenticular lens comprises a surface having a central region including prisms and peripheral regions comprising lenticular lenses.
5. A light-diffusing attachment as claimed in claim 1 , wherein the lenticular lens comprises a double-sided lenticular lens.
6. A light-diffusing attachment as claimed in claim 1 , wherein the lenticular lens includes a first lens having the first array and a second lens having the second array.
7. A light-diffusing attachment as claimed in claim 1 , wherein the first orientation is substantially ninety degrees rotated relative to the second orientation.
8. A light-diffusing attachment as claimed in claim 1 , wherein the first array comprises stepped lenses.
9. A light-diffusing attachment as claimed in claim 1 , wherein the frame includes a supporting flange that at least partially defines a groove that extends at least partially around the frame, the groove configured to receive a portion of the housing to removably couple the frame and the housing.
10. A light-diffusing attachment as claimed in claim 9 , wherein the flange includes an opening configured to allow the portion of the housing to pass through the opening to facilitate coupling the frame and the housing.
11. A light-diffusing attachment for a light engine having a housing, comprising:
a frame adapted to be secured to the housing of the light engine;
a refracting lens supported by the frame;
a diffuser supported by the frame; and
a folding mirror supported by the frame that directs light from the light engine to the refracting lens and the diffuser,
wherein the refracting lens includes a first array with a first orientation and a second array with a second orientation different than the first orientation.
12. A light-diffusing attachment as claimed in claim 11 , wherein the folding mirror includes an array of stepped mirrors.
13. A luminaire comprising:
a light engine having a light source and a housing; and
a light-diffusing attachment, comprising:
a frame secured to the housing of the light engine;
a refracting lens supported by the frame; and
a diffuser supported by the frame,
wherein the refracting lens comprises a lenticular lens,
wherein the lenticular lens includes a first array with a first orientation and a second array with a second orientation different than the first orientation.
14. A luminaire as claimed in claim 13 , wherein the light-diffusing attachment further includes a folding mirror supported by the frame that directs light from the light engine to the refracting lens and the diffuser.
15. A luminaire as claimed in claim 14 , wherein the folding mirror includes an array of stepped mirrors.
16. A luminaire as claimed in claim 13 , wherein the lenticular lens comprises a surface having a central region including prisms and peripheral regions comprising lenticular lenses.
17. A luminaire as claimed in claim 13 , wherein the lenticular lens comprises a double-sided lenticular lens.
18. A luminaire as claimed in claim 13 , wherein the lenticular lens comprises a first lens having the first array and a second lens having the second array.
19. A luminaire as claimed in claim 13 , wherein the first orientation is substantially ninety degrees rotated relative to the second orientation.
20. A luminaire as claimed in claim 13 , wherein the first array comprises stepped lenses.
21. A luminaire as claimed in claim 13 , wherein the frame includes a supporting flange that at least partially defines a groove that extends at least partially around the frame, wherein the light engine includes a tab located within the housing, and wherein the groove receives the tab to removably couple the frame and the housing.
22. A luminaire as claimed in claim 21 , wherein the flange includes an opening that allows the tab to pass through the opening to facilitate coupling the frame and the housing.
23. A luminaire comprising:
a light engine having a light source and a housing; and
a light-diffusing attachment, comprising:
a frame secured to the housing of the light engine;
a refracting lens supported by the frame;
a diffuser supported by the frame; and
a folding mirror supported by the frame that directs light from the light engine to the refracting lens and the diffuser,
wherein the refracting lens includes a first array with a first orientation and a second array with a second orientation different than the first orientation.
24. A luminaire as claimed in claim 23 , wherein the folding mirror includes an array of stepped mirrors.
