LED lights very not good, see its heat dissipation function is good. With the increase of the LED street lamp power, the size of the radiator and weight also needs corresponding increase. To reduce the high power LED street lamp radiator component, for the demand of cooling methods and cooling structure and data optimization planning in many aspects. LED street light weight main resolution by the weight of the radiator, LED street lamp with excellent waterproof dustproof ( IP) Protection grade ( Such as IP45 and above) , but the outstanding IP protection and tend to hinder the LED heat dissipation. How to deal with this contradiction is the LED street lamp can not be ignored when planning an important direction. LED street light, heat dissipation ability directly affect the actual luminous power of leds and their life spans. LED for the electroluminescent devices, in the process of their work only 15% to 25% of the electric energy into light energy, almost all other electrical energy into heat energy, raise the temperature of the LED, LED lights fell sharply. If the LED junction temperature beyond the maximum allowable temperature ( General is 125 ℃) , the LED will be damaged due to overheating. Thus in LED lamps and lanterns of planning, one of the most important job is cooling plan. LED street lamp light failure is small, light failure is less than 3% a year, still meet the requirements of road use illuminance to 10 years, and high pressure sodium light failure is big, has fallen by more than 30% a year or so. So the LED street light on the design of the use of power can be lower than the high-pressure sodium lamp. LED street light automatic control and energy saving device, can realize under the condition of meet the requirements of different times lighting the biggest possible to reduce the power, saves the electricity. Intelligent LED street lamp which can realize computer dimming, period and control, light control, temperature control, remote control, humanized functions such as automatic inspection.
