摘要
针对目前便携式矿灯用锂离子电池在过充、过放电时均会损坏电池,低温特性也较差等缺点,介绍了一种LED新型矿灯。主要介绍供电用锂离子电池特性以及LED光源驱动电路的工作原理,并对锂离子电池如何在矿灯特殊照明产品中安全、方便、稳定地使用进行了研究分析。
The lithium battery of portable miner＇ s lamp will be damaged when over-charge, over-discharge or in the low temperature environment. So the new features of LED lithium battery and the working principle of LED light source drive circuit are introduced. And analyzes how to operate more safely, conveniently and stably of the lithium battery in special miner＇s lighting product.
