Why to protect LED bulb chip

     White LED bulb chip has a lot of advantages, it is more and more into people's daily life, its use is now becoming very large. It is a new device and has its own characteristics. White LED chip is a voltage sensitive device. Each LED chip working current is not more than 20mA, more than LED chip will be very easy to be burned. LED bulb light if it is normal to use, its life is very long. But the people in the actual use of LED chip are often prone to bad. Why? Because you do not take into account the characteristics of LED chip and give it a protective circuit.
     LED chip is a photoelectric semiconductor device, easy by static damage in assembly process. This requires the electrostatic protection in the assembly process. We find that many LED lamp manufacturers do not have this concept or simply do not understand, this is not good.
     LED bulb chip is in the actual work of 20mA current is the upper limit, but often due to various reasons in the use of the current increase, if not to take protective measures, the increase of current over a certain period of time and amplitude after LED chip will damage.
