LED Heat SinkAn element capable of rapidly dissipating and releasing the heat generated by LED chips into the environment. Simply having a certain thermal dissipation area is insufficient for a heat sink; the materials used to make the heat sink must have adequate thermal conductivity, meaning high thermal conductivity, to continuously transfer the chip's heat and eventually dissipate it into the environment; of course, for thermal conductive materials, in addition to thermal conductivity, they should also possess characteristics such as low density, low cost, high strength, and ease of processing.
