An elevator emergency lighting system comprises a control chip, a lift car lighting source fault detection circuit module, a mains supply power failure detection circuit and a battery voltage and battery charging detection circuit. The lift car lighting source fault detection circuit module at least comprises an LED lighting lamp constant-current drive circuit and a lift car illumination detectioncircuit, and the lift car illumination detection circuit is used for collecting the illumination in a lift car, converting the illumination into an illumination signal which can be recognized by thecontrol chip, and judging whether a standby LED light source is started by driving the LED illuminating lamp constant-current driving circuit or not according to the collected illumination intensity.Aiming at the fault of a lift car lighting source, the standby light source can still be automatically started through the system, and alarm processing is carried out. According to the present invention, the problem that the working time of emergency lighting cannot be verified during existing maintenance can be effectively solved, the fault type of an emergency power supply can be automatically identified, the overall emergency power supply replacement cost is greatly saved, the maintenance efficiency is improved, and the energy conservation and environmental protection are achieved.

    一种电梯应急照明系统,包括:控制芯片、轿厢照明光源故障检测电路模块、市电掉电检测电路、电池电压及电池充电检测电路;所述轿厢照明光源故障检测电路模块至少包括:LED照明灯恒流驱动电路和轿厢照度检测电路;轿厢照度检测电路用于采集轿厢内的光照,并转为控制芯片能识别的光照信号,根据采集光照强度判断是否通过驱动LED照明灯恒流驱动电路启动备用LED光源。本发明针对轿厢照明光源故障,依然可以通过本发明所述系统自动启动备用光源,并做报警处理;还可以有效解决了现有维护时无法对紧急照明的工作时间进行验证的难题;还可自动识别应急电源的故障类型,大大节约了整体更换应急电源的成本,提高检修效率,节能环保。
