Abstract:
A solid state area light and spotlight having a solid state light source such as LEDs, tapered light guides, and external thermal guides. The area light includes a flared light guide, and the spotlight includes a light guide with a closed end. The light guides are coupled to the light source for receiving and distributing light from the light source with the distribution being based in part upon the shape and taper of the light guides. The thermal guide provides for thermal conduction from the light source and dissipating heat through convection and radiation for cooling the light.
