摘要： A heat pipe (10) includes a pipe body (20) having an inner wall (22) and a screen mesh (30) disposed on the inner wall of the pipe body. The screen mesh is in the form of a multi-layer structure with at least one layer thereof having an average pore size different from that of the other layers. The layer with large-sized pores is capable of reducing the flow resistance to the condensed fluid to flow back, whereas the layer with small-size pores is capable of providing a relatively large capillary pressure for drawing the condensed fluid from the condensing section to the evaporating section.

摘要： 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.
