Phosphor-containing LED light bulb
An LED bulb, which includes a shell, a filler material within the shell of the bulb, at least one type of phosphor dispersed inside the filler material and at least one LED within the shell.
1. A light-emitting diode (LED) bulb comprising:
a shell having a volume defined within the shell;
a fluid that fills the volume defined within the shell of the bulb;
at least one type of phosphor distributed throughout the fluid; and
at least one LED disposed within the volume defined within the shell.
2. An LED bulb as set forth in claim 1 , wherein the fluid is thermally conductive.
3. An LED bulb as set forth in claim 1 , wherein the at least one phosphor is uniformly distributed throughout the fluid.
4. An LED bulb as set forth in claim 1 , wherein the at least one phosphor has a non-uniform distribution throughout the fluid.
5. An LED bulb as set forth in claim 1 , wherein the at least one phosphor is comprised of at least two phosphors, and wherein the at least two phosphors comprises at least one phosphor having a different distribution from the others throughout the fluid.
6. An LED bulb as set forth in claim 1 , wherein the at least one LED is a blue or ultraviolet LED without a phosphor.
7. An LED bulb as set forth in claim 1 , wherein the at least one LED is a blue or ultraviolet LED die.
8. A light-emitting diode (LED) incandescent bulb replacement comprising:
an incandescent bulb-shaped shell having a volume defined within the shell;
a fluid that fills the volume defined within the shell of the bulb;
at least one type of phosphor distributed throughout the fluid; and
at least one LED disposed within the volume defined within the shell.
9. An LED bulb as set forth in claim 8 , wherein the fluid is thermally conductive.
10. An LED bulb as set forth in claim 8 , wherein the at least one phosphor is uniformly distributed throughout the fluid.
11. An LED bulb as set forth in claim 8 , wherein the at least one phosphor has a non-uniform distribution throughout the fluid.
12. An LED bulb as set forth in claim 8 , wherein the at least one phosphor is comprised of at least two phosphors, with at least one phosphor having a different distribution from the other phosphors throughout the fluid.
13. An LED bulb as set forth in claim 8 , wherein the at least one LED is a blue or ultraviolet LED without a phosphor.
14. An LED bulb as set forth in claim 8 , wherein the at least one LED is a blue or ultraviolet LED die.
