Abstract

A housing for a plurality of light emitting diodes includes a housing providing a heat sink, where the heat sink includes a plurality of protrusions. A control board can be removably coupled to the heat sink and the control board can provide an aperture to receive a lens housing and an aperture to receive a coupling member to secure the control board to the heat sink. Further, a plurality of light emitting diode light engines can be mounted to the control board where the individual heat sink protrusions of the plurality of heat sink protrusions align with individual light engines of the plurality of light engines.

Claims

1. A device for dissipating heat from light emitting diodes, comprising:

a heat sink with a plurality of protrusions;

a control board coupled to the heat sink;

a plurality of light emitting diode light engines mounted to the control board;

wherein the individual heat sink protrusions of the plurality of heat sink protrusions align with individual light engines of the plurality of light engines and the control board secures the light engines against the heat sink protrusions.

2. The device of claim 1, wherein the control board couples to the heat sink with a securing member.

3. The device of claim 1, wherein the plurality of light engines produce red, green and blue light.

4. The device of claim 1, wherein at least one individual light engine produces red, green and blue light.

5. The device of claim 1, wherein the control board provides a plurality of apertures for receiving a light engine lens housing.

6. The device of claim 1, wherein the light engines operate less than or equal to a die junction temperature of 125°

C.

7. The device of claim 1, wherein the light engines extend from the control board a uniform distance.

8. A light fixture, comprising:

a housing providing a heat sink, the heat sink providing a plurality of protrusions;

a control board coupled to the heat sink;

the control board providing an aperture to receive a lens housing and an aperture to receive a coupling member to secure the control board to the heat sink;

a plurality of light emitting diode light engines mounted to the control board;

wherein the individual heat sink protrusions of the plurality of heat sink protrusions align with individual light engines of the plurality of light engines.

9. The housing of claim 8, wherein the plurality of light engines produce red, green and blue light.

10. The housing of claim 8, wherein at least one individual light engine produces red, green and blue light.

11. The housing of claim 8, wherein the light engines extend from the control board a uniform distance.

13. The method of manufacturing of claim 11, further comprising the step of securing the control board to the heat sink with a securing member.

14. The method of manufacturing of claim 11, further comprising the step of applying a thermal interface material between the light engine and the heat sink protrusion.

15. The method of manufacturing of claim 11, further comprising the step of wiring the control board to receive signals from a control console.

12. A method of manufacturing a light emitting diode housing, comprising the steps of:

providing a housing with a heat sink having a plurality of heat sink protrusions;

providing a control board with a plurality of light engines;

assembling the housing with the control board arranged such that the individual light engines of the plurality of light engines align with the individual heat sink protrusions of the plurality of heat sink protrusions.
