Abstract

A lighting assembly comprising a socket housing having a lamp socket electrically connected to an electrical junction, a trim removably attached to the socket housing about its opening; and one or more solid-state light emitting device associated with the trim. The one or more solid-state light emitting devices may be inconspicuous to the casual observer when they are not illuminated. The one or more solid-state light emitting devices are operatively connected to the electrical junction such that they can receive electrical power when the electrical junction is operatively connected to mains power. The connection between the LEDs and the junction may be controlled manually, by a backup power supply circuit, motion detector, or light detector to provide, among other possibilities, mood lighting, backup lighting or work lighting, in addition to the light provided by a lamp in the socket.

Claims

1. A lighting assembly comprising:

a socket housing defining an opening and having a lamp socket disposed therein, the lamp socket being electrically connected to an electrical junction and adapted to receive a primary lighting source;

a trim removably attached to the socket housing about the opening; and

a first solid-state light emitting device mounted to the trim, the first solid-state light emitting device being operatively connected to the electrical junction such that it is capable of receiving electrical power to cause the first solid-state light emitting device to emit light when the electrical junction is operatively connected to mains power.

2. The lighting assembly of claim 1, wherein the first solid-state light emitting device is mounted to the trim such that when the lighting assembly is installed the first solid-state light emitting device is inconspicuous to the casual observer.

3. The lighting assembly of claim 2, further comprising a power supply operatively associated to mains power for providing the electrical power to the first solid-state light emitting device.

4. The lighting assembly of claim 3, further comprising a backup battery operatively connected to the first solid-state lighting emitting device to provide the electrical power when the power supply does not.

5. The lighting assembly of claim 4, wherein the battery is rechargeable.

6. The lighting assembly of claim 3, wherein the power supply is controlled by a switch.

7. The lighting assembly of claim 6, further comprising a programmable circuit operatively configured to control the switch based on a predetermined time and a predetermined period.

8. The lighting assembly of claim 6, further comprising a motion detector operatively connected to the switch to control activation of the switch.

9. The lighting assembly of claim 6, further comprising a light detector operatively connected to the switch to control activation of the switch.

10. The lighting assembly of claim 1, wherein the first solid-state light emitting device is one of a plurality of solid-state emitting devices mounted to the trim.

11. The lighting assembly of claim 10, wherein the plurality of solid-state emitting devices are mounted in a pattern to the trim.

12. The lighting assembly of claim 1, wherein the first solid-state light emitting device is disposed in relation to the lamp socket such that the first solid-state light emitting device provides accent lighting.

13. A trim for a lighting assembly, said lighting assembly comprising a first connector, a socket housing having an opening and a lamp socket disposed therein, the first connector and the lamp socket each being electrically connected to an electrical junction, the trim comprising:

a first solid-state light emitting device mounted to the trim; and

a second connector operatively connected to mate to the first connector such that the first solid-state light emitting device is capable of receiving electrical power to cause the first solid-state light emitting device to emit light when the electrical junction is operatively connected to mains power.

14. The trim of claim 13, wherein the first solid-state light emitting device is mounted to the trim such that when the lighting assembly is installed the first solid-state light emitting device is inconspicuous to the casual observer.

15. The trim of claim 13, wherein the first solid-state light emitting device is one of a plurality of solid-state emitting devices mounted to the trim.

16. The trim of claim 15, wherein the plurality of solid-state emitting devices are mounted in a pattern to the trim.

17. The trim of claim 13, wherein trim has a trim body and a trim ring disposed around the trim body, the first solid-state emitting device being mounted to one of the trim body and the trim ring.

18. The trim of claim 13, wherein the first solid-state light emitting device is disposed in relation to the lamp socket such that the first solid-state light emitting device provides accent lighting.

19. A method for providing alternative lighting from a lighting product, the lighting product comprising a socket housing having an opening and having a lamp socket disposed therein, the lamp socket being electrically connected to an electrical junction, the method comprising:

providing a trim having a first solid-state light emitting device mounted thereto;

attaching the trim to the opening of the socket housing; and

operatively connecting the first solid-state light emitting device to the electrical junction.

20. The method of claim 19, wherein operatively connecting further includes activating a switch to enable the electrical power to reach the first solid-state light emitting device.

21. The method of claim 20, wherein the switch is activated by a programmable circuit operatively configured to activate the switch based on a predetermined time and a predetermined period.

22. The method of claim 21, wherein the switch is activated by a motion detector.

23. The method of claim 21, wherein the switch is activated by a light detector.
