LM-80 in LED Lighting

The life of LED is still a characteristic of long -term attention. The theoretical life of LED is very long. Like the traditional light source uses a 2H45MIN and the 15 minutes cycle test to the end of life, the measurement of LED products is obviously unrealistic. Therefore, it is necessary to use the accelerated aging life test for LED products. At the same time, it should also test the performa...

How to Use TM-21 and LM-80 to Estimate LED Luminaries Life?

LED has the features of long time. According to different power drivers and use conditions, the life of LED can be up to 50,000 hours or more. LED will not extinguish directly like other light source but decay gradually. Therefore, luminous decay will lead to output low light after long time use, which will make products not meet requirements. And how to use TM-21 to estimate LED luminaries life? ...
