Description
技术领域
本发明涉及煤矿设备技术领域，具体是一种为煤矿井下各个通道，重要场所提供应急照明的一种隔爆兼本质安全的LED应急照明灯。
背景技术
目前，我国煤矿井下所使用的各类灯具中还未有锂电池供电的LED应急照明灯，主要原因是锂电的防爆要求高，处理困难，对与锂电池连接的导线和连接方式均匀特殊处理，再者现有的 LED应急照明灯亮度由于电池的限制普遍不够，照射距离较短，但利用较高频率的灯珠又会导致持续时间变短，强光容易刺伤工人的眼睛，上述问题有待改进。
发明内容
本发明针对现有技术的不足，提供了以下技术方案：一种矿用隔爆兼本质安全型LED应急照明灯，包括主壳体，主壳体由上部的隔爆腔和下部本安腔构成，隔爆腔顶端设置有提手，其特征在于隔爆腔通过隔板分成左右两个腔室，左腔室内设置有电路控制板、右腔室内设置有锂电池组，所述隔板上开设有用于锂电池组和电路控制板导线连接的走线孔，走线孔内设置有保护管，保护管包括用于抗电磁干扰的金属管、设置于金属管两端的橡胶套，橡胶套外端套有金属帽，隔爆腔与本安腔通过防爆穿腔接线端板连接，所述本安腔内设置有LED光源组件。
作为优选，LED光源组件包括LED灯珠铝基板，LED灯珠铝基板上安装有LED灯珠，设置于LED灯珠铝基板下方的喇叭形集光罩，喇叭形集光罩小径口与LED灯珠铝基板外周边密封连接，大径口下方安装有PC灯面板，PC灯面板固接于本安腔底端，PC灯面板包括基板、基板上表面的粘合层以及粘合层上的玻璃层，玻璃层为波浪形或锯齿形，玻璃层表面涂覆有一层氨基甲酸酯甲基丙烯酸酯，厚度为5~15微米，基板表面有磨砂层，
作为优选，右腔室内的锂电池组周围填充有环氧树脂阻燃层。
作为优选，喇叭形集光罩包括铁片层，铁片层表面镀一层光反射层构成反光镜面；在光反射层外上表面加盖一透明保护层。
作为优选，光反射层为白瓷施釉层。
所述电路控制板内包括电源切换电路，锂池充电保护电路，交流直流转换电路，LED恒流驱动等组成。。当接通电源后，电源板会接通充电电路给电池充电，充满后自动断开，当电池电压低于某个值时会自动开启充电电路。当外部交流电断电后，通过内部转换由锂电源供电，将 LED灯点亮照明。
本发明的有益效果是：本发明的隔爆兼本质安全型LED灯能广泛应用于有爆炸性气体（甲烷）和煤尘的环境中，而且把锂电池电源管理、LED驱动，本质安全保护电路做在一起，减少了使用的空间,节约了成本，结构紧凑，体积小，运输和安装非常方便，并且光照强度大，对工人眼睛刺激小。
