There is electricity in the lighting room of Manak car, but there is no electricity in the car.

The lighting circuit of the elevator is independent. Generally, building lighting is powered by electricity, but the elevator has a special separate circuit, which can avoid the elevator tripping and the car lighting is not affected.

The lighting circuit of elevator is divided into well lighting, car lighting, partial well lighting and control cabinet lighting. The lighting power supply of the car comes from the onboard cable and control cabinet, which is suspended at the bottom of the car and the top of the shaft. At half the height of the shaft, move it upward 1 and fix it to 2m. Depending on the height of the shaft, there is one or two fixed points between this fixed point and the top of the shaft.

When the elevator or the outside is out of power, there is a storage battery in the control box at the top of the car, which automatically supplies power for emergency lighting in the car, usually 12V. In case of power failure, there is a relay in the control box at the top of the carriage, which automatically disconnects and cuts off the 220V power supply in the carriage. The purpose is that some elevators are equipped with power failure emergency devices, power failure rescue devices and power failure automatic leveling devices. The storage battery capacity of these devices is limited, and they are only used by the main engine in case of power failure. Cut off the 220V power supply in the car, to prevent unnecessary power consumption of lighting and fans in the car, and fully supply power to the main engine.
