we should pay attention to when buying LED lights? We are buying the LED street lamp mainly pay attention to is the luminous efficiency, light failure, weight problems, and the cooling these points, so now Australia solar street lamps, lighting to give everyone carefully say these points. Luminous efficiency: mature technology, high power LED light source can meet the general street light needed. The average high pressure sodium lamp light efficiency is 100 lm/W, commonly used in high power LED is 50 - 60 lm/W, with foreign LED chip can reach 80 lm/W, the higher luminous efficiency, energy saving effect means that the better, which is to choose one of the most important indicator LED lights. Leds, however, does not have explicitly stipulated in the standard, so must be carefully confirmed when purchasing LED lights. Droop: some businesses, in order to reduce costs, with hundreds of 0. The small power LED 5 w. However, this kind of small power LED light failure is very serious, its light failure and 80% of life is only 1000 hours. As the need for long-term use, so the street light is absolutely not allowed the use of this kind of small power LED, selects the high power LED Generally refers to more than 30 w) , the light failure will be much better. Weight problem: LED street light due to the complexity of high technical content, composition and so on reasons, some high power lamp holder will weigh far more than ordinary high pressure sodium lamp, so the support for the corresponding material requirements are higher. However, some LED lights have been as far as possible to reduce the weight of the LED lamp holder, from the original single lamp holder about 30 kilograms, dropped more than 10 kilograms, weight loss and the trend of decline further. Heat: because the LED is a semiconductor components, its chip is affected by temperature and reduced to 30% of the initial luminous flux, will lose the meaning of lighting, or put an end to the life, the life of the high power LED street light in theory - 3 50000 hours, but the premise is have good heat resistance. Be worth what carry is, have adopted the world's leading domestic acicular heat dissipation technology. ,
