Design and manufacturing technology of LED street lamp power supply more should pay attention to quality problems

LED street lamp is mainly used in outdoor environment, to have the wind rain, lightning in bad environment; In southern China, the outside temperature part time could be as high as 40 ℃ to 50 ℃; But in the cold north, outside the temperature may be low to - part time 20℃－- 30℃。 So the LED street lamp power supply design and manufacturing technology are more pay attention to the quality problem. Most of the outdoor LED street lamp failure can be attributed to the power failure, lighting LED street lamp design of face special challenges, most challenge does not exist in the traditional power supply applications. The harsh conditions of high temperature ( Lead to circuit board temperature over 100 ℃) Closely adjacent, combined with the source and load, make the standard adapter technology cannot work at all. Besides, the telecom converter of the efficient methods to deal with high temperature, in the applications of LED street light only partially effective. Therefore, the modular design of LED street lamps, drive LED lamp series, in parallel with more than 90% of the working efficiency, without the need for aluminum electrolytic capacitors. In addition, the PI also provides a highly integrated, high frequency resonant converter scheme, by will increase the efficiency of power supply in light load to more than 92% to reduce the stress of the power supply.
