摘　　要：简述消防疏散照明中的灯具选择依据,并对疏散照明中的光源选择、安装高度、布置间距进行分析;定义疏散照明控制光源,并在此光源参数下推导出不同安装高度和间距下的地面最低水平照度计算公式,进而给出不同疏散照度标准下适宜的应急照明灯具安装间距。同时对疏散照明中的照度均匀度进行简要探讨,并结合蓄电池特性和直流电源电压降,分析应急照明回路中的灯具配接数量。The basis for the selection of luminaires in fire evacuation lighting is introduced,the selection,installation height,and arrangement spacing of light sources in fire evacuation lighting are analyzed,and control light source is defined.Besides,the calculation formula for the minimum horizontal illuminance on the ground for different installation heights and spacing is derived from such light source parameters,and thus appropriate installation spacing for emergency lighting luminaires under different standards for evacuation illuminance are given.Meanwhile,a brief discussion is conducted on the illuminance uniformity of evacuation lighting,and the number of luminaires provided in the emergency lighting circuit is analyzed based on battery characteristics and the voltage drop of DC power supply.
