Generally Speaking,When you just buy the led light is very bright.However,after some time,the light will be more and more dark.Why?Let me tell you why.

If you want to know why the led lights will be become more and more dark.First,let's know the LED name"Led Light Decay" Led Light Decay means when the led light lit up after some time,the light strong compare the begining of light strong is lower and can not restore.The lower lights parts call LED decay.

LED Decay Graph

Though Led Lights has a bit change compare with Incandescent lamp,still not complete change the issue for Led Decay. Led light decay have 2 factors as below:

1.Led lights has itself quality issue

If using bad quality Led chip,brightness decays fast,or defects in the production process,Led chip temperature is too high leads to decay too much

2.Led lamp heat dissipation performance

Good Heat dissipation,led working temperature is low,decay is low,led life prolong more

So you know the result of light decay,prolong the led lamp life is ok.Though the light decay cannot change,the degree of light decay can be controlled

If wants to lower the light decay to small,3 points tell you how to do

1.Choose good quality led lamp

When you purchase the led lamp,please try to select good quality and good heat dissipation led lamp,and reduce the led lamp work load during using them.Thus,you can delay the spead of the light decay leads to prolong the led lamp lifespan.

2.Correct Install

Prerequisite to extend the life of the lamp:If you not install the correct,so the led lamp will be bad easily,even has burst or short circuit that will be dangrous.

3.Avoid frequent lighting

When adding the luminaire, you need to pay attention to it. Do not switch frequently. When the luminaire is frequently started, the current through the light source is greater than the current during normal operation, so that the dead temperature will rise sharply, which will greatly reduce the service life of the luminaire.
