Abstract

Reflector designs for a large area panel light source create induced draft cooling means adjacent to the panel light source. The panel light source has a wavelength conversion element on a solid state light source for emitting light of a first and second wavelength to form a broader emission spectrum of light from the panel light source.

Claims (10)

1 . A self-cooling suspended ceiling solid state light fixture comprising

at least one self-cooling solid state panel light wherein the emitting and cooling surfaces of the at the least one self-cooling solid state panel light are substantially the same.

2 . The self-cooling suspended ceiling solid state light fixture of claim 1 wherein substantially all the heat generated is transferred to the illuminated side of the installation.

3 . The self-cooling suspended ceiling solid state light fixture of claim 1 comprising

at least one thermally conductive translucent element, at least one LED, at least one electrical interconnect, and optionally at least one wavelength conversion element.

4 . The self cooling suspended ceiling solid state light fixture of claim 3 wherein the at least one LED and at least one electrical interconnect are mounted to said at least one thermally conductive translucent element.

5 . The self cooling suspended ceiling solid state light fixture of claim 3 wherein the at least one wavelength conversion element is on the surface of, within, or otherwise mounted to the at least one thermally conductive translucent element.

6 . The self-cooling suspended ceiling solid state light fixture of claim 3 wherein the LED is mounted and interconnected either imbedded or on the surface of the thermally conductive translucent element

7 . The self-cooling suspended ceiling solid state light fixture of claim 3 wherein the LED is mounted and interconnected either imbedded into or on the surface of the thermally conductive translucent element and the LED is position to that light emitted by the LED is directed away from the output surface of the light source.

8 . The self-cooling suspended ceiling solid state light fixture of claim 7 where the light that is emitted by the LED is reflected by a back reflector and then passes back through the translucent thermally conductive element before being emitted by the panel light source.
