Abstract
In order to solve problems that miner's lamp cannot work for a long time due to limited capacity of its lithium battery and there are hidden dangers for charging in coal mine underground,a new type of lithium battery miner's lamp using wireless charge was designed which can be charged both by lamp-charging rack on ground and by wireless power transmission technology in coal mine underground.In coal mine underground,wireless power transmitting circuit in base of the miner's lamp wireless charger converts electric energy into electromagnetic wave to surrounding space,wireless power receiving circuit of the miner's lamp receives the electromagnetic wave signal through coil and converts it into DC 5 V signal,and then uses special high-precision charging circuit to charge lithium battery of the miner's lamp.The test results show that the miner's lamp has advantages of high conversion efficiency of electric energy,and the charging process is in accordance with charging characteristics of the lithium battery with high safety.关键词
