Abstract
A solid state light having a solid state light source such as LEDs, and optical guide, and a thermal guide. The optical guide is coupled to the light source for receiving and distributing light from the light source, and the thermal guide is integrated with the optical guide for providing thermal conduction from the solid state light source and dissipating heat through convection for cooling the light.

A light with integrated optical and thermal guides, comprising:
- a light source;
- an optical guide coupled to the light source for receiving and distributing light from the light source;
- and
- a thermal guide integrated with the optical guide for providing thermal conduction from the light source for cooling the light.
A light with integrated optical and thermal guides, comprising:
- a light source;
- an optical guide comprising a material having an exterior surface and an interior surface, wherein the optical guide is coupled to the light source for receiving and distributing light from the light source through the exterior surface;
- and
- a thermal guide integrated with the interior surface of the optical guide for providing thermal conduction from the light source for cooling the light.
A light with integrated optical and thermal guides, comprising:
- a light source;
- an optical guide comprising a material having an exterior surface and an interior surface, wherein the optical guide has light injection, light transport, and light extraction elements in order to distribute light from the light source;
