At present, many cities have installed the LED street light, use the field gradually expand, but also have a lot of people reflect, LED street light in the process of continuous use, can appear sometimes LED lights will be failure, stop lights, and use time is not long, but this is the way it is? As we all know, the LED road lamp lights main key is to see the LED light source, if some factors affect the LED light source, is the cause for the failure of LED road light light. Led the change of environmental temperature and heating in the encapsulation structure of mechanical stress can destroy chips, gold wire and electrode, the connection between the pins, or gold thread breakage, cracks, mechanical loss led to the led failure. The thermal stress generated by high temperature can also lead to chip light-emitting efficiency is lower, droop speed up, color migration and other serious consequences, is the need to focus on the LED reliability problems. To improve the reliability of LED street light, we must take the reliability of the corresponding technology, the LED encapsulation structure as far as possible to eliminate or reduce the influence of these factors, and improve the ability of resist the influence of these factors.
