Solid state lighting device and method employing heat exchanger thermally coupled circuit board

摘要: An illumination device comprises a circuit board that carries solid-state light sources and heat transfer structure to which the is intimately physically coupled such curved along at least one of longitudinal dimension or lateral thereof. Such may allow less fasteners be used than would otherwise possible, while maintaining close contact over large portion surface area. Some embodiments employ clamp, for example peripheral clamp as cover bezel clamp.
