LED street lamp cooling technology, the general use of the way for the thermal plate, is a 5mm thick copper plate, in fact, is the temperature plate, the heat are temperature off; also installed heat sink to heat, but the weight is too large.Weight is very important in the street lamp system, because the street is 9 meters high, if the risk is too heavy to increase, especially in the typhoon, the earthquake may have accidents. Domestic manufacturers use the world's first acupuncture heat dissipation technology, needle radiatorOf the thermal efficiency than the traditional sheet radiator has greatly improved, can make LED junction temperature than ordinary radiator 15 ℃ above, and the waterproof performance is better than ordinary aluminum radiator, while the weight and volume also improved The In addition, for high-power LED lamps developed graphite heat sink also has good thermal conductivity and thermal performance.
