Abstract
A solid state light module incorporating light emitting diodes (LEDs) disposed on a metal substrate, a solid state lighting system employing such modules, and method of replacing LEDs of the light modules are provided. The metal substrate may allow for lower LED junction temperature and, hence, a longer device lifetime. In addition, the metal substrate may allow for the potential omission of a heat sink, which may reduce light module size, when compared to conventional solid state light emitters.
