Why do lamps suffer from light decay?

There are two main reasons for the light failure of lamps and lanterns; one is that the LED chip quality is not good, resulting in the brightness of the lamps and lanterns attenuation is too fast; there is another important reason is that the LED chip heat dissipation is not good, resulting in the lamps and lanterns to appear serious light failure.

LED is afraid of heat is a well-known thing in the industry, LED ideal working temperature is between -5 ~ 0 °, but this is basically impossible, heat will affect the LED lamps and lanterns light decay and life, LED at work, there will be about 80% of the electrical energy into heat, 20% of the electrical energy into light energy, LED heat sink is to give the LED heat dissipation, because the LED chip at work, his When the LED chip is working, his ambient temperature and the light rate inversely proportional to the relationship, the higher the temperature, the lower the light rate, when the temperature reaches the maximum temperature of the LED chip, the lamps will be broken.

Light failure is a necessary process of lamps and lanterns, we should try to pick lamps and lanterns with good quality and heat dissipation performance, in the use of the process should also try to reduce the workload of the lamps and lanterns, in order to slow down the speed of light failure and extend the life of the lamps and lanterns.
