The causes of LED light decay

LED light decay means that after a long time of use, the brightness of LED lights will have different degrees of dimming, which is the light decay of the LED lights.

Today, the LED lighting made by diverse LED suppliers will have different light decay. Even high-power LEDs have light decay that has an inseparable relationship with working temperature. It is decided by chip, phosphor and packaging technology. Nowadays, the lumens decline of LED lights is one of the hot concerns for the LED light industry. There are 2 key reasons for the light decay of LEDs:

First of all, the quality of LED lights:
1. A few LED lights manufacturers select the low quality LED chip to cut the cost, which makes the lumination of such lights are attenuated faster.
2. The producing technique is flawed, the heat made by the LED chip's working can't be released from the PIN efficiently, which bring about the overtemperature and light decay.

Secondly, the working conditions:
1. The LED is ordered to be driven by a constant current. However, in practical use, many customers will use voltage driven that cause the LED decay to increase.
2. The actual input current is higher than the rated current of LEDs.

Actually, there are lots of causes of the light decay of LED lights. The foremost crucial problem is the efficiency of heat dissipation. Many LED lighting suppliers do not focus on the heat dissipation of their lights, the light decay of these LED lights will over others with the well cooling design after a long period of use. The heat resistance of the chip, the cooling effect of the PCB, the base, the colloid, the gold wire, and other materials are also associated with the light decay of LEDs.

At present, the LED lighting market is paying more and more attention to the quality of LED lights. As the LED light strips and LED plant grow lights supplier in China, we also use the mature manufacturing technology and select excellent raw materials to guarantee the reliable quality of our products.
