LED lighting is an important product energy saving and emission reduction

Followed by LED lights high-power leds wild scale more and more widely use, heat dissipation question is becoming more and more outstanding. In some categories and become a professional conduct. Has outstanding advantages to environmental protection, especially in the street lamp, courtyard light and high lamp, landscape lamp, etc in high power LED as light source, lighting lamps and lanterns to save electricity effect is particularly significant. With China's rapid economic growth, in the case of dynamic growing progress lighting products energy efficiency is very necessary, during which Beijing energy conservation and emissions reduction products in LED street light hasten to replace the traditional street lamp together also show out some questions: caused by poor heat leakage appearance such as emerge in endlessly. The practice of the heat dissipation ability directly affect the LED project-light lamp luminous power and become old, yea, so excellent heat dissipation planning is necessary to consider the point. Actually I think to deal with field of high power LED lighting lamps and lanterns cooling question, first from the heat dissipation material, choose the right information ability is very good performance is the function of the radiator. Outdoor lighting work environment is more complex, the temperature, ultraviolet radiation, humidity, rain and snow weathered, sand and dust, chemical gas and other natural conditions, the influence of the radiator data has some features are: high and low temperature resistance, ageing resistance, waterproof, etc. Wild high-power LED lighting radiator main still is to use copper or aluminum alloy and other metal materials. Shockproof project-light lamp in the nature of the thermal conductivity of metals is * *, especially inductive * * ratio of copper, aluminum. But considering the ductility and aluminum processing function is very good, let's high power radiator are selection of aluminum alloy. Beijing energy conservation and emissions reduction products field, such as high-power LED street lamp lighting lamps and lanterns of the weight of the primary resolution by the weight of the radiator. With the increase of power, the radiator dimensions and weight are also required to add, will put forward higher need to chips and stent. Thus, the weight loss is particularly necessary. In addition to plastic, use ceramic also can reduce the weight of lamps and lanterns, but ceramic and plastic package ceramics and other materials first is still useful to in indoor lighting. Because ceramic itself is more brittle, machining function also is not high, so is usually used in under 10 w leds. Like LED project-light lamp lights, LED landscape light field, such as high power lighting seldom useful to existing skills and techniques are not support high power leds use ceramic. For a utility cooling parts, thermal conductivity is not single. Especially for the cooling need high power LED radiation and convection cooling method is very important.
