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 pr 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?
In order that LED industry persons have a clear concept of TM-21 and learn how to use TM-21 to estimate LED products. We will make 4 programs to explain the application and prediction method of LM-80-08 and TM-21-11:
Step 1: LED components manufacturers do at least 6,000 hours test at 3 temperatures (55C°/85 C°/Optional Temperature) for LED Source (Package/Array/Module) according to LM-80-08.
