Abstract

An LED lighting system comprises an LED assembly for emitting light. A bulb comprises an enclosure and an optic element in the enclosure for receiving the light from the LED assembly and transmitting the light from the enclosure. An Edison-style or other traditional-style base is provided on the bulb for connecting the bulb to an Edison-style or other traditional-style socket.

Claims

1. An LED lighting system comprising;

an LED assembly for emitting light;

a bulb comprising an enclosure and an optic element in the enclosure for receiving the light emitted by the LED assembly and dispersing the light from the enclosure, and a base connected to the enclosure, the base being configured to be engageable with a socket.

2. The LED lighting system of claim 1 wherein the base comprises an Edison-style base and the socket comprises an Edison-style socket.

3. The LED lighting system of claim 2 further comprising an optical transmitter that receives the light emitted from the LED assembly and transmits the light to the Edison-style socket.

4. The LED lighting system of claim 3 wherein the optical transmitter comprises a fiber optic cable.

5. The LED lighting system of claim 3 wherein the LED assembly is positioned in a fixture remote from the socket and the optical transmitter is removably connected to the fixture.

6. The LED lighting system of claim 3 wherein the optical transmitter is operatively coupled to an optical connector in the Edison-style socket.

7. The LED lighting system of claim 3 further comprising a lens in the fixture for receiving the light from the LED assembly and focusing the light to be received by the optical connector.

8. The LED lighting system of claim 1 wherein the base comprises an Edison-style base that engages an Edison socket.

9. The LED lighting system of claim 1 further comprising a lens for receiving the light from the LED assembly and focusing the light to be received by the optic element.

10. The LED lighting system of claim 1 wherein the optic element is transparent.

11. The LED lighting system of claim 10 wherein the optic element comprises a light emitting area.

12. The LED lighting system of claim 11 wherein the light emitting area comprises a light scattering surface.

13. The LED lighting system of claim 10 further comprising a wire connected to the optic element adjacent the light emitting area.

14. The LED lighting system of claim 1 further comprising a switch for altering current delivered to the LED assembly, the color of the light changing in response to the current.

15. The LED lighting system of claim 2 wherein the LED assembly is located in the Edison-style socket.

16. The LED lighting system of claim 1 wherein the bulb is releasably engageable with the socket.

17. The LED lighting system of claim 16 wherein the base comprises an Edison-style base and the socket comprises an Edison-style socket.

18. The LED lighting system of claim 16 wherein the base comprises a traditional-style base and the socket comprises a traditional-style socket.

19. The LED lighting system of claim 1 further comprising a switch for lowering current delivered to the LED assembly, the color of the light changing to red/orange/red-orange in response to the lowering of the current.

20. The LED lighting system of claim 1 wherein the LED assembly is located in the base.
