LED Street Light purchase points

　　Road lighting production and life are closely related with people , with the accelerated process of urbanization in China , LED lights with directional light, low power consumption , the driving characteristics of a good , fast response , high shock resistance , long life and other advantages will gradually go green into people's vision to become the world's most dominant next-generation alternative to traditional energy-saving light sources , therefore , LED lights will become the best choice for a road lighting energy saving.

　　1. Luminous efficiency

　　LED lighting technology matures, the power LED light source can meet the general street light flux. General high pressure sodium lamp luminous flux is 100LM / W, which is commonly used in high-power LED 50-60LM / W. With the best LED chip abroad can reach 80LM / W, luminous efficiency is higher, which means better energy efficiency, which is the most important indicators to select the LED lights. However, LED's standards did not clearly defined, so when purchasing LED lights must be carefully confirmed.

　　2. LED street light failure

　　Now some businesses, in order to reduce costs, they only use small 0.5W power LED, However, this low-power LED light failure is very serious, the 80% light fades of the life is only 1000 hours . So, as long-term use of the street needs, it is absolutely not allowed to use such small power LED, the choice of powerful LED (over 30W), the fades would be much better.

　　3. LED lights weight problem

　　Due to technical content, complex composition and other reasons, some of the high-power lamp will far exceed the weight of ordinary high-pressure sodium, so the corresponding support material requirements are higher. However, some manufacturers already prepared to reduce the weight from the original single lamp about 30 kilograms down to more than 10kg as much as possible, there is further downward trend for weight reduction.

　　4. LED lights heat

　　Because LED is a semiconductor component, and its chips affected by the temperature and decreased to 30% of the initial luminous flux, then illumination will lose significance, that is the end of life, in theory, high power LED street life is 3-5 million hours, but which is an important prerequisite for good heat dissipation. It is worth mentioning that the country has adopted the world's leading manufacturers of needling cooling technology.
