led outdoor lighting will cause serious problems to the LED light failure because the work environment is more complex, it will be affected by temperature, UV light, humidity, rainy rain , dust, chemical, gas and other natural conditions. Therefore, considered all above, outdoor lighting designers should consider when designing these external environmental factors impact on LED outdoor lighting.
Choosing what kind of cooling method has a direct impact on the cost of the lamps. Overall consideration, to select the best design products supporting programs : Housing and radiator as a whole in order to solve the LED heat problem, this approach is better, generally use aluminum or aluminum alloy, copper or copper alloys, and other alloys good thermal conductivity. Cooling air convection cooling, heat and strong wind cooling heat pipe cooling, (jet refrigeration heat is similar to a heat pipe heat, but the structure is more complicated.) LED outdoor lighting lampshade design selection is also critical, currently used transparent PMMA, PC materials.
Outdoor LED chip packaging technology : the current domestic production of LED lamps ( main street) are based on more than 1W of LED strings to be assembled in parallel, this method is higher thermal resistance of advanced packaging technology products, it is not easy to create high quality lamps . Or the use of 30W, 50W or more modules to be assembled in order to achieve the required power, the LED packaging materials are useful in epoxy resin, useful silicone encapsulation. The difference between the two is: less temperature epoxy resin, a long time easy to aging. When you select, you should know that Silicone encapsulated has better temperature resistance.
