【正文】 racteristics. Emergency evacuation lights with a wallmounted, portable, hanging installation. Users install the evacuation light, you can choose according to the actual situation of different installation methods. Emergency lighting batteries are used in fire emergency light battery, when the AC input to charge the battery using the charging circuit, the normal AC power is disconnected electricity off our normal circumstances, fire emergency lighting lamps battery to power the light bulb. Now the state fire emergency light power supply emergency lighting batteries required time shall not be less than 90 minutes. Fire emergency light batteries are mainly used to provide power to fire emergency lighting is a major fire emergency lighting installations, emergency lighting and fire with fire when used in normal lighting system can not provide illumination for the evacuation, the special status continued to work fire fighting and rescue operations and emergency lighting. Key words: Fire emergency lights, principles, circuits, fault analysis 哈爾濱應(yīng)用職業(yè)技術(shù)學(xué)院畢業(yè)設(shè)計（論文） 目 錄 摘 要 .................................................................
