Abstract

The present disclosure provides a solid state lighting fixture that can be used in outdoor and indoor recessed lighting applications. The solid state lighting fixture has a recessed housing configured to be installed in a recess, and a solid state light assembly capable of being secured to the housing outside the recess. The solid state light assembly is at least partially made of a heat dissipating material capable transferring heat generated by the solid state light assembly to ambient air.

Claims

1. An SSL fixture comprising:

a recessed housing configured to be installed in a recess; and

an SSL assembly capable of being secured to the recessed housing outside the recess, the SSL assembly being at least partially made of a heat dissipating material capable transferring heat generated by the SSL assembly to ambient air.

2. The SSL fixture of claim 1, wherein the SSL assembly comprises:

an external housing; and

an SSL light engine secured within a recess within the external housing and having one or more SSL light elements mounted to a light engine board, wherein the external housing is made of the heat dissipating material capable transferring heat generated by the SSL light engine to ambient air.

3. The SSL fixture of claim 2, wherein the SSL assembly further comprises a cover positioned over the SSL light engine and secured to the external housing.

4. The SSL fixture of claim 2, wherein the heat dissipating material comprises cast aluminum.

5. The SSL fixture of claim 1, wherein the recessed housing comprises:

a driver compartment including dimmable drivers; and

a junction box, the junction box being partitioned into a first compartment for alternating current (AC) wiring and a second compartment for low voltage wiring electrically coupled to the dimmable drivers.

6. The SSL fixture of claim 1, further comprising:

dimmable drivers; and

a thermal regulation circuit electrically coupled to the dimmable drivers, the thermal regulation circuit causing the dimmable drivers to reduce wattage used by an SSL light engine in response to a detected increase in temperature of the SSL light engine above a predefined threshold temperature.

7. The SSL fixture of claim 1, wherein the recessed housing is secured to the SSL assembly with at least two screws.

8. The SSL fixture of claim 2, further comprising:

a lens secured on a distal side of the light engine with regard to recessed housing.

9. The SSL fixture of claim 8, wherein the lens is a diffusing lens.

10. An SSL assembly comprising:

an external housing; and

an SSL light engine secured within a recess within the external housing and having one or more SSL light elements mounted to a light engine board;

wherein the external housing is made of a heat dissipating material capable transferring heat generated by the SSL light engine to ambient air.

11. The SSL assembly of claim 10, further comprising:

a cover positioned over the SSL light engine and secured to the external housing.

12. The SSL assembly of claim 10, wherein the heat dissipating material comprises cast aluminum.

13. The SSL assembly of claim 10, further comprising:

at least two screws to secure the SSL assembly to a recessed housing configured to be installed in a recess.

14. The SSL assembly of claim 13, further comprising:

a lens positioned on a distal side of the SSL light engine with regard to the recessed housing.

15. The SSL assembly of claim 14, wherein the lens is a diffusing lens.

16. The SSL fixture of claim 10, wherein the SSL light engine is adaptable to operate at a plurality of different wattages.

17. An SSL fixture comprising:

a recessed housing configured to be installed in a recess; and

an SSL assembly having an SSL light engine with one or more SSL light elements, the SSL assembly capable of being secured to the recessed housing outside the recess;

dimmable drivers electrically coupled to the SSL light elements; and

a thermal regulation circuit electrically coupled to the dimmable drivers, the thermal regulation circuit causing the dimmable drivers to reduce wattage used by the SSL light engine in response to a detected increase in temperature of the SSL light engine above at least one predefined threshold temperature.

18. The SSL fixture of claim 17, wherein the thermal regulation circuit causes the dimmable drivers to reduce wattage used by a SSL light engine in an inversely proportional response to a detected increase in temperature of the SSL light engine above a predefined threshold temperature.

19. The SSL fixture of claim 17, wherein the recessed housing is secured to the SSL assembly with at least two screws.

20. The SSL fixture of claim 17, further comprising:

a diffusing lens positioned on a distal side of the SSL assembly with regard to the recessed housing.
