The circuit uses highfrequency switching power supply with hight effictive,high constancy and high integration density to control IC, which achieves stable property and low temperature rise. This products usese constant current anf constant voltage with high –precisionto control circuit .it can change up to batteries of lithium manganate,lithiun phosphate,plumbic acid and ni –mh in diferent ways. It is with many kings of protection functions including constant current and overcharging protector,to increase service life and security of batteries.

 

This product uses dedicated switch controller with low internal resistance to connect live parts . when miner’s lamp is off charger (charger is cut off or charger is put away from lamp-chanrging rack),live part would automatically separate from battery,which would make the maximum increase oh safty factor and the maximum decrease of wastage. We are the first one to make quiescent dissipation to be zero at the national level.

 

Main light sourse use constant-current-discharge, and discharge current is constant and ajustale.

 

Main light sourse is made available to be sections with constant current,in order to increase the service life of battery. Normally the constant current is more than 3.8v for lithium managanate battery and it is current limitting under 3.8V. current of main light sourse would decrese as the voltage of th battery does ,so that the service of the battery would be rolonged..

We can make this kind of miner’s lamp to be one main light sourse with seven secondary if the customers would like .(when switching to the secondary light ,the main light sourse would also light up with low current). This kind of product is a revolutionary achievement in the field of miner’s lamp.,which changes the whole history the the field for it plays a great driving role in this industry . Tests standards as belong :Temperature :20±5°C.relativehumidity:45%-75%.Atmosphere pressure :86Kpa -106Kpa.
