How to choose appropriate cooling material for Chinese street light?

  It is beyond discussion that a great deal benefits for Chinese street light arising from the LED lighting come forth compared to traditional products as its wider application, longer life, higher efficiency, and more environment-friendly. LED lights last longer and efficiently by means of transforming energy into light to cut the heat as much as possible.

  Nevertheless, there is still far more inevitable heat arising from the lit light, which could exert adverse effects to Chinese street light including eliminating longevity, harming lighting effects, lowing CRI, etc. Hence, it is the key part to cut heat for showing the superior solid state light (SSL) superiority.

  Actually, operating temperatures concerns immensely with for Chinese street light life－the higher temperature, the shorter life. A normal LED temperature not merely extends service life but also makes more lights. There are many approaches and methods improving LED heat management, amid which two methods including encapsulated resin materials and thermal conductive interface material are not bad idea.

  Thermal conductive interface material is designed as binding between components and radiator, speeding up heat loss to lower the operating temperatures. Likewise, solidified materials are used as binding covering RTV or epoxy materials, which are selected according to adhesion strength and operating temperature.

  Another choice is heat-conducting encapsulated resin material, which provides indispensable protection and heat sink for equipment. The encapsulated resin material choice is wide including epoxy resin, polyurethane resin, and silicone resin.

  Polyurethane resin has a good flexibility, especially in low temperature, the main advantage compared to epoxy resin. Likewise, silicone resin has a same function, but has higher prices. As for epoxy resin, it is a far more rugged product, providing brilliant protection in harsh and awful environment. Encapsulated resin material contributes to design a number of custom LED lights as need of customers.

  As electronics industry develops rapidly, to be specific in LED application, cooling material should be improved accordingly, which makes great contribution for Chinese street light improvement and development.
