The invention provides an elevator car illuminating lamp controller. The controller is characterized in that a commercial power input unit is connected with commercial power, and an output end is connected with the input end of a driving unit; a primary winding of a transformer is connected with the commercial power input unit, a secondary winding is connected with the input end of a second rectifying and filtering circuit, and the second rectifying and filtering circuit is connected with an illuminating lamp; and an emergency power supply unit is connected with an emergency power supply of anelevator control system, the output end of a booster circuit is connected with the second rectifying and filtering circuit, the control end of a second control chip and the driving unit are connectedwith a control circuit, and when the driving unit stops supplying power, the control circuit stops supplying power to the control end, the second control chip works, and power is supplied to the illuminating lamp through the boosted circuit. According to the controller, normal illuminating and emergency illuminating are integrated, the emergency power supply of the elevator control system is utilized, the installation is easy, the complexity of the controller is lowered, the reliability is improved, and the difficulty of daily maintenance is lowered.

    本发明提供一种电梯轿厢照明灯控制器,该控制器的市电输入单元与市电连接,输出端与驱动单元的输入端连接;变压器的初级绕组与市电输入单元连接,次级绕组与第二整流滤波电路的输入端连接,第二整流滤波电路与照明灯连接;应急供电单元与电梯控制系统的应急电源连接,升压电路的输出端与第二整流滤波电路连接,第二控制芯片的控制端、驱动单元分别与控制电路连接,控制电路在驱动单元停止供电时,停止向控制端供电,第二控制芯片工作,并通过升压电路向照明灯供电。本发明将常态照明与应急照明整合在一起,并利用电梯控制系统的应急电源,安装简单、降低了控制器的复杂度、提高了可靠性,降低了日常维护的难度。
