  • Solid state lighting device and method employing heat exchanger thermally coupled circuit board
    Patent number: 9241401
    Abstract: An illumination device comprises a circuit board that carries solid-state light sources and a heat transfer structure to which the circuit board is intimately physically coupled such that the circuit board is curved along at least one of a longitudinal dimension or a lateral dimension thereof. Such may allow less fasteners to be used than would otherwise be possible, while maintaining close contact over a large portion of the surface area. Some embodiments may employ a clamp, for example a peripheral clamp such as a cover or bezel clamp.
    Type: Grant
