LED lamp component

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 

1.Main and ancillary a whole,double light source way 

2.Red and green double charging indication 

3.Short circuit self restoration function can be selected 

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

5.Main light distributaries can be selected
