摘 要 近年来，大型公建越来越多，尤其是人员较为密积的酒店、商场、写字楼，在紧急状况下的人员疏散是一个很现实和重要的问题，这对应急照明系统的合理设置提出了新的问题。 应急照明包括以下几种： （1）正常照明失效时，为继续工作（或暂时继续工作）而设的备用照明 （2）为使人员在火灾情况下，能从室内安全撤离至室外（或某一安全地区）而设置的疏散照明； （3）正常照明突然中断，为确保处于潜在危险的人员安全而设置的安全照明。 就其功能而言，应急照明是十分重要的，它涉及到人身安全的问题，所以应急照明系统设计的合理性是其可靠性的关键。 本应急灯由市电和后备电池供电，能在停电之后自动点亮一段时间，适合农村或经常停电的地区作为应急照明之用。在市电正常时，应急灯熄灭，市电经整流，滤波后对后备电池供电。当夜晚市电突然中断时，应急灯启动。 【关键词】 应急灯; 整流滤波; 逆变器。 Abstract In recent years, large-scale male constructed are getting more and more, particularly the personnel denser products hotel, the market, the office, under panic stations personnel dispersal were one very realistic and the important question, this asked the new question to the emergency lighting systems reasonable establishment. Emergency lighting including the following several kinds: (1) Normal illumination expiration, is continues to work (or continues the emergency lighting which temporarily work) supposes (2) To cause the personnel in the fire situation, can from the indoor safe evacuation the dispersal illumination which establishes to outdoor (or some security area); (3) The normal illumination sudden stop, to guarantee that is in safety lighting which the potential hazard the personal security establishes. Speaking of its function, the emergency lighting is very important, it involves to the personal safety question, therefore the emergency lighting system designs rationality is its reliable key. This emergency light by the city electricity and the reserve battery power supply, can after the power cut lightens period of time automatically, suits the area which the countryside or cuts power frequently to take emergency lighting. Is normal when the city electricity, the emergency light extinguishes, the city electricity passes through the rectification, after the filter constant voltage, to reserve battery power supply. That night when afternoon market electricity sudden stop, the emergency light starts. 【KEYWORD】Emergency light; Rectification filter; Invertor 。 目 录
