LED component element

 

Introduction                          

This product is the charge-discharge control circuit that special designed for Lithium miner’s lamp. It adopts linear way charging according to li-ion standardad of constant-voltage charge model ,the key light source adopts the way that discharge by constant current,ensure the LED lifetime.

 

Feature 

Main and ancillary a whole,double light source way

Red and  green double charging indication

With short circuit self restoration function can be selected

Low tension transition function can be selected(mean low voltage turn fill light bright)

Main light distributaries can be selected
