The LED drive circuit determines that LED service time
The led drive circuit has a important impact on the led system .the drive circuit can be changed into fit drive voltage form adapter. For Led drive circuit and LED load provide electrical energy.
The mainly function of LED drive circuit:
What character traits does such LED drive circuit; it should have constant current characteristics.
Especially as input voltage of adapter changes, the led current still can keep immobile.
- Make sure that Led load current is stable
- To void that the LED drive current to exceed the maxim rated value.
- The LED chromaticity are consistent with LED bright
Low-power scheme is best.
The Scale diagram of LED Damage
Damage rate of LEDs as 10%
Controller of LED as 7%
LED install as 31%
The drive of LED as 52%
