Branch when applying led traffic lights appear some questions, such as the led in the first use of time is can work normally, but lit for a period of time in the future will appear dim light, shining, faults, such as continuous bright scene, bring damage to the product. This is the cause of the scene are:

The use of the product, the welding process, such as welding temperature welding time is too long, not to do a good job of anti-static, and so on, these questions the basic is in the process of encapsulation.

Led traffic light itself may produce manufacturing quality. LED aging method contains aging aging constant current and constant voltage. Constant current source is safe at all times remains the same, if the frequency of the question, that is not constant current questions, current ripple can plan into RMS in secure communication which is constant, but the power supply can't call it is a constant current source. The most fit LED current characteristics of constant current aging, aging is the most scientific way. Over current impact aging is manufacturer's latest chooses a method of aging by using frequency adjustment, current adjustable constant current source is aging, and can pick many conventional aging can't pick out the risk.

Aging is a major guarantee the reliability of the electronic products, is an indispensable part of product output, aging LED products in the future can improve efficiency of late can help to use the safe.
