Abstract

A lighting device includes two different types of light emitting elements and two different types of power sources for selective illumination. In particular, the lighting device has AC-LEDs and DC-LEDs that are illuminated by an AC power source and a DC power source, respectively, without the need for current conversion. The AC-LEDs and DC-LEDs may be disposed within a LED lamp which is installable in any preexisting light fixture.

Claims

1. A lighting device comprising:

a light housing having an electrical connector for receiving power from an AC power source;

a battery coupled to the light housing for supplying DC battery power;

at least one light-emitting element disposed within the housing for receiving AC power from the AC power source; and

at least one light-emitting element disposed within the housing for receiving DC power from the battery.

2. The lighting device of claim 1 wherein the light-emitting elements are LEDs.

3. The lighting device of claim 1 further comprising:

a heat sink for receiving heat from the LEDs.

4. The lighting device of claim 3 wherein the heat sink is an aluminum disk.

5. The lighting device of claim 1 wherein the battery is a rechargeable battery.

6. The lighting device of claim 1 further comprising:

a receiver coupled to the lighting device and configured to receive a signal for selectively determining the power source.

7. The lighting device of claim 6 further comprising:

a transmitter which remotely transmits data to the receiver.

8. The lighting device of claim 7 wherein the transmitter is a handheld device.

9. The lighting device of claim 7 wherein the data is received over a ZigBee network.

10. A LED lamp comprising:

a lens for providing radiation of light;

at least one AC-LED selectively providing illumination through the lens;

at least one DC-LED selectively providing illumination through the lens;

a heat sink coupled to the LEDs and absorbing heat therefrom; and

a lamp base for containment of the LEDs and the heat sink.

11. The LED lamp of claim 10 further comprising:

a battery disposed within the lamp base and supplying a DC power source.

12. The LED lamp of claim 10 wherein the lamp base has a connector for receiving an electrical connection from an AC power source.

13. The LED lamp of claim 10 further comprising:

a receiver coupled to the lamp and configured to receive a signal for selectively determining the source of power.

14. A light device comprising:

a plurality of AC-LEDs;

a plurality of DC-LEDs;

an AC electrical connector for supplying AC power to the AC-LEDs; and

a battery for supplying DC battery power to the DC-LEDs.

15. The light device of claim 14 wherein the LEDs and battery are contained within a lamp assembly that includes an engagement arrangement for selectively engaging the lamp assembly within a socket.

16. The light device of claim 14 wherein the DC-LEDs and battery are contained within a base that includes an engagement arrangement for selective engagement within a socket, and wherein the AC-LEDs are carried in a lighting device separate from and engageable with the base.

17. The light device of claim 14 further comprising:

a photosensor for detecting a low light condition.

18. The light device of claim 14 wherein the battery is a rechargeable battery.

19. The light device of claim 14 wherein the light device is a down-lighting bulb.

20. The light device of claim 14 wherein the light device is a linear-lighting bulb.
