Glass LED light bulbs
A glass LED bulb, which includes a body of glass, the body having at least one hollow portion, and at least one LED contained within the at least one hollow portion. A thermally conductive material is preferably included within the at least one hollow portion. The body of glass can be bulb-shaped or alternatively shaped like an incandescent bulb.
1. A glass LED bulb comprising:
a solid body of glass, the body having at least one hollow portion formed therein;
at least one LED contained within the at least one hollow portion; and
a thermally conductive material within the at least one hollow portion,
wherein the thermally conductive material fills the at least one hollow portion.
2. A glass LED bulb as set forth in claim 1 , wherein the body of glass has a bulb-shape.
3. A glass LED bulb as set forth in claim 1 , wherein the body of glass has an incandescent bulb-shape.
4. A glass LED bulb as set forth in claim 1 , wherein the thermally conductive material is a fluid, a gel or a plastic.
5. A glass LED bulb as set forth in claim 4 , wherein said fluid, gel or plastic is optically transparent.
6. A glass LED bulb as set forth in claim 4 , wherein said fluid, gel or plastic contains means, or is itself the means, to disperse and/or to color shift the light.
7. A glass LED bulb as set forth in claim 4 , wherein said fluid, gel or plastic is electrically insulating.
8. A glass LED bulb as set forth in claim 4 , wherein said fluid contains a means to gel when exposed to air.
9. A glass LED bulb as set forth in claim 4 , wherein said fluid, gel or plastic is hydrated polyacrylimide.
10. A glass LED bulb as set forth in claim 4 , wherein said fluid, gel or plastic provides mechanical relief for the glass.
11. A glass LED bulb as set forth in claim 1 , wherein the at least one hollow portion comprises a plurality of hollow portions having interconnections.
12. A glass LED bulb as set forth in claim 11 , wherein said interconnections are used to interconnect said at least one LED.
13. A glass LED bulb as set forth in claim 1 , further comprising a power source for the LEDs, which is included in the bulb.
14. A glass LED bulb as set forth in claim 13 , wherein said power source for the LEDs is compatible with pre-existing power sources, permitting the bulb to be used in pre-existing fixtures.
15. A glass LED bulb as set forth in claim 1 , wherein said bulb-shaped body of glass contains means to disperse and/or means to color shift the light.
16. A glass LED bulb as set forth in claim 15 , wherein said means to disperse the light is bubbles in said glass.
17. A glass LED bulb as set forth in claim 15 , wherein said means to disperse the light is a collection of Mie scatterers in said glass.
18. A glass LED bulb as set forth in claim 15 , wherein said means to color shift the light is a dye in said glass.
19. A glass LED bulb as set forth in claim 15 , wherein said means to color shift the light is a collection of Rayleigh scatterers in said glass.
20. A glass LED bulb as set forth in claim 1 , wherein interconnections between the at least one LEDs is made on a printed circuit board.
