Claim Text:
1. An optical device, comprising: a solid state light source; a reflector positioned to reflect light from said light source into directional light emission, heat from said light source at least partially transmitting into said reflector; and a first heat sink mounted to said reflector positioned in thermal contact with said light source such that heat from said light source transmits into said first heat sink, said first heat sink comprising a thermally conductive conformable porous material layer adjacent said light source, said porous material layer comprising a 3-dimensional pore structure comprising interconnected pores, with the surfaces of said pore structure providing increased surface area for heat to dissipate into the ambient compared to bulk heat sinks, said porous material layer further comprising a graded porous material region wherein part of said porous material region comprises a higher density pore structure than the remainder of said region, said first heat sink shaped to fit around said reflector, wherein said reflector is configured to spread heat from said light source throughout said first heat sink; wherein said reflector comprises a reflective metal and wherein said reflector is affixed to said first heat sink.
