機車照明控制系統由兩個亮度傳感器和一個主控制器組成，可以根據車廂內部的光強自動調節LED照明燈具的亮度。亮度傳感器安裝在車廂的兩側，檢測車廂內部光強；主控制器安裝在每節車廂的控制柜內，通過PWM輸出模塊與LED驅動電路的調光模塊相連，對LED燈光的亮度進行實時調節，節約了列車照明用電量，使車廂內的照明實現智能化、節能化，提高了乘客乘車舒適度的同時也減輕了列車工作人員需手動調節燈光的工作負擔。

    The locomotive lighting control system is composed of two light sensors and a main controller, which can adjust the brightness of LED lighting lamps automatically according to the light intensity of the compartment's interior. Light sensors are installed on both sides of the compartment to detect the interior light intensity. The main controller is installed in each compartment of the control cabinet, connecting with dimming module of the LED driving circuit through the PWM output module, and adjusts LED light brightness in real time. The system saves the energy of the train lighting, makes the lighting inside intelligent and energy saving, improves the comfort for passengers and also reduces the train staff workload.
