Hybrid lens for solid state light source device
View Patent ↗A hybrid lens for a solid state light source device is provided. The hybrid lens includes a first component and a second component. The first component has a first side and a second side oppositely disposed thereto. The first side is positioned facing a solid state light source. The second component is attached to the first side of the first component. The first component includes a flame retardant material, such as a glass or a filled polymer. The second component includes a non-flame retardant material, such as an unfilled polymer.
1. A hybrid lens for a solid state light source device, comprising:
a first component having a first side and a second side oppositely disposed thereto, wherein the first side is positioned facing a solid state light source; and
a second component attached to the first side of the first component;
wherein the first component comprises a flame retardant material, and wherein the second component comprises a non-flame retardant material.
2. The hybrid lens of claim 1 , wherein the flame retardant material of the first component comprises glass.
3. The hybrid lens of claim 2 , wherein the non-flame retardant material of the second component comprises an unfilled polymer.
4. The hybrid lens of claim 3 , wherein the unfilled polymer comprises an unfilled polycarbonate.
5. The hybrid lens of claim 3 , wherein the unfilled polymer comprises an unfilled polymethylmethacrylate.
6. The hybrid lens of claim 3 , wherein the unfilled polymer comprises a combination of an unfilled polycarbonate and an unfilled polymethylmethacrylate.
7. The hybrid lens of claim 1 , wherein the flame retardant material of the first component comprises a polymer containing a fill of flame retardant materials.
8. The hybrid lens of claim 7 , wherein the non-flame retardant material of the second component comprises an unfilled polymer.
9. The hybrid lens of claim 8 , wherein the unfilled polymer comprises an unfilled polycarbonate.
10. The hybrid lens of claim 8 , wherein the unfilled polymer comprises an unfilled polymethylmethacrylate.
11. The hybrid lens of claim 8 , wherein the unfilled polymer comprises a combination of an unfilled polycarbonate and an unfilled polymethylmethacrylate.
12. The hybrid lens of claim 7 , wherein the flame retardant material of the first component comprises a polycarbonate containing a fill of flame retardant materials.
13. The hybrid lens of claim 12 , wherein the non-flame retardant material of the second component comprises an unfilled polymer.
14. The hybrid lens of claim 13 , wherein the unfilled polymer comprises an unfilled polycarbonate.
15. The hybrid lens of claim 13 , wherein the unfilled polymer comprises an unfilled polymethylmethacrylate.
16. The hybrid lens of claim 13 , wherein the unfilled polymer comprises a combination of an unfilled polycarbonate and an unfilled polymethylmethacrylate.
17. The hybrid lens claim 1 , wherein the first component is shaped correspondingly with the second component.
18. The hybrid lens of claim 1 , wherein the first component is shaped differently from the second component.
19. The hybrid lens claim 1 , wherein the first component comprises, at least in part, an enclosure of the solid state light source device.
20. A hybrid lens for a solid state light source device, comprising:
a first component having a first side positioned facing a solid state light source and an oppositely disposed second side; and
a second component fixed to the first side of the first component;
wherein at least the first component is flame-retardant.
