When in use, the human body sensor detects whether there is a person in the elevator car and transmits a corresponding signal to the controller. When the controller determines that there is a person in the elevator car, the lighting fixture is turned on to provide lighting for the elevator car.

In addition, the personnel in the elevator car can adjust the light color and brightness of the lighting fixture through the lighting adjustment switch. Specifically, when the knob is rotated between 0 degrees and 120 degrees, the knob is in the first gear. At this time, the color adjustment encoder converts the rotation angle into a first electrical signal and transmits it to the controller through the PCB main control board. After the controller receives the first electrical signal, it controls the first light source to light up, and the second light source and the third light source do not work.

At this time, the light emitted by the lighting fixture is Yellow light; and, when the knob is turned to 120 degrees, the pinion gear drives the potentiometer shaft to rotate once and reset, and then the knob can continue to be rotated within the range of 120 degrees to 240 degrees, and the light of the lighting fixture will not be changed during this process. Instead, the large gear drives the pinion gear and the potentiometer shaft to rotate, so as to adjust the brightness of the second light source.

When the knob is turned between 240 degrees and 360 degrees, the knob switches to the third gear. During the rotation of the knob, the encoder shaft and the large gear will be driven to rotate by the transmission mechanism. At this time, the color adjustment encoder converts the rotation angle to After the third electrical signal is transmitted to the controller through the PCB main control board, the controller controls the third light source to light up after receiving the third electrical signal, while the first light source and the second light source do not work.
