1、哈尔滨应用职业技术学院毕业设计（论文）摘要消防应急灯，适用于消防应急照明，是消防应急中最为普遍的一种照明工具，应急时间长，高亮度具有断电自动应急功能。消防应急疏散指示灯具有耗电小、亮度高、使用寿命长等特点，边上设计有电源开关和指显灯，适合工厂、酒店、学校、单位等公共场所以备停电作应急照明之用。消防疏散指示灯是选用工业塑料和高亮度的灯泡制成，材料不老化、散热快、抗冲击等特点。消防应急疏散指示灯具有壁挂式、手提式、吊式安装方式。用户在安装疏散指示灯时，可以根据实际情况选择不同的安装方式。消防应急照明灯电池是用于消防应急灯中的蓄电池，当有交流电输入时利用充电电路给蓄电池充电，正常交流电
2、断开时也就是我们的正常用电断开的情况下，消防应急照明灯的蓄电池给灯泡供电而点亮。现在国家消防应急灯电池要求提供应急照明电源时间不得短于90分钟。消防应急灯电池主要用来为消防应急照明提供电源，是消防应急照明灯的重要装置，与消防应急照明灯一起用于是在发生火灾时正常照明系统不能提供照明时为人员疏散、特殊岗位坚持工作以及灭火救援行动提供应急照明。关键词：消防应急灯、原理、电路、故障分析II哈尔滨应用职业技术学院毕业设计（论文）AbstractFireemergencylights,emergencylightingforfire,fireemergencyisthemostcommont
