Abstract

A light engine housing comprising a mixing chamber element, a driver chamber element and/or a connection element, one or more of which is removable. A light engine comprising (1) a light engine housing and (2) a mixing chamber module and/or a driver module removably attached to and/or positioned in the light engine housing. Also, a light engine comprising (1) a light engine housing and a mixing chamber module and/or a driver module. Also, a solid state light engine comprising a light engine housing comprising at least a first connection element.

First claim

The invention claimed is:

1. A light engine housing comprising:
at least a first mixing chamber element,
at least a first connection element,
at least a first driver chamber element, and
at least a first component selected from among driver modules, trim elements, fixture elements and heat sink modules,
the first connection element configured to hold in place relative to the first mixing chamber element the first component selected from among driver modules, trim elements, fixture elements and heat sink modules,
the first driver chamber element and the first mixing chamber element a single-piece are unitary structure.

2. A light engine housing as recited in claim 1 , wherein the mixing chamber element at least in part defines a mixing chamber in which light from at least one solid state light emitter mixes prior to exiting the light engine housing.

3. A light engine housing as recited in claim 1 , wherein the driver chamber element defines a driver compartment that has a size and shape that accommodate at least one component selected from among driver components and power supply components.

4. A light engine comprising a light engine housing as recited in claim 1 and at least one component selected from among driver components and power supply components.

5. A light engine comprising a light engine housing as recited in claim 1 and at least one solid state light emitter.

6. A lighting device comprising a light engine housing as recited in claim 1 and at least one other component selected from among fixture elements, trim elements and heat sinks, wherein the connection element provides both mechanical connection and thermal coupling between the light engine housing and the at least one other component selected from among fixture elements, trim elements and heat sinks.

7. A light engine housing, comprising:
at least a first driver chamber element;
at least a first mixing chamber element; and
at least a first connection element,
the first driver chamber element and the first mixing chamber element a single-piece are unitary structure,
the first connection element removably connected to at least one of (1) an exterior of the first driver chamber element and (2) an exterior surface of the first mixing chamber element.

8. A light engine housing as recited in claim 7 , wherein
an entirety of the first driver chamber element is to a first side of a first plane,
an entirety of the first mixing chamber element is to a second side of the first plane.

9. A light engine housing as recited in claim 7 , wherein:
the first connection element is configured to hold in place relative to the first mixing chamber element at least one component selected from among driver modules, trim elements, fixture elements and heat sink modules.

10. A light engine housing as recited in claim 7 , wherein the light engine housing further comprises at least one driver module in or on the driver chamber element.

11. A light engine housing as recited in claim 7 , wherein the light engine housing further comprises at least one mixing chamber module in or on the mixing chamber element.

12. A light engine housing as recited in claim 7 , wherein the mixing chamber element at least in part defines a mixing chamber in which light from at least one solid state light emitter mixes prior to exiting the light engine housing.

13. A light engine housing as recited in claim 7 , wherein the driver chamber element defines a driver compartment that has a size and shape that accommodate at least one component selected from among driver components and power supply components.

14. A light engine housing, comprising,
at least a first driver chamber element;
at least a first mixing chamber element; and
at least a first driver module,
the first driver chamber element and the first mixing chamber element a single-piece are unitary structure.

15. A light engine housing as recited in claim 14 , wherein the light engine housing further comprises at least one mixing chamber module in or on the mixing chamber element.

16. A light engine housing as recited in claim 14 , wherein the mixing chamber element at least in part defines a mixing chamber in which light from at least one solid state light emitter mixes prior to exiting the light engine housing.

17. A light engine housing as recited in claim 14 , wherein the driver chamber element defines a driver compartment that has a size and shape that accommodate at least one component selected from among driver components and power supply components.

18. A light engine housing as recited in claim 14 , wherein
an entirety of the first driver chamber element is to a first side of a first plane,
an entirety of the first mixing chamber element is to a second side of the first plane.

19. A light engine housing as recited in claim 14 , wherein:
the first connection element is configured to hold in place relative to the first mixing chamber element at least one component selected from among driver modules, trim elements, fixture elements and heat sink modules.

20. A light engine housing, comprising,
at least a first driver chamber element;
at least a first mixing chamber element; and
at least a first mixing chamber module;
the first driver chamber element and the first mixing chamber element a single-piece are unitary structure.

21. A light engine housing as recited in claim 20 , wherein the light engine housing further comprises at least one driver module in or on the driver chamber element.

22. A light engine housing as recited in claim 20 , wherein the mixing chamber element at least in part defines a mixing chamber in which light from at least one solid state light emitter mixes prior to exiting the light engine housing.

23. A light engine housing as recited in claim 20 , wherein the driver chamber element defines a driver compartment that has a size and shape that accommodate at least one component selected from among driver components and power supply components.

24. A light engine housing as recited in claim 20 , wherein
an entirety of the first driver chamber element is to a first side of a first plane,
an entirety of the first mixing chamber element is to a second side of the first plane.

25. A light engine housing as recited in claim 20 , wherein:
the first connection element is configured to hold in place relative to the first mixing chamber element at least one component selected from among driver modules, trim elements, fixture elements and heat sink modules.
