The light control unit 20 is connected to the light-emitting panel unit 30, the light adjustment unit 40, and the power supply unit 50 through a cable. The master control unit 10 is connected to the power supply unit 50 through a cable. The power supply unit 50 is used to provide working voltage.

[0028] The light control unit 20 is turned on by the instruction information transmitted by the main control unit 10 and the power supply unit 50, and controls the light panel unit 30 and the light adjusting unit 40 to adjust the light for capturing the face.

[0029] In use, the main control unit 10 transmits instruction information to the power supply unit 50, so that the light control unit 20 is turned on with the power supply unit 50, receives the working voltage transmitted by the power supply unit 50, and then controls the light panel unit 30 and the light adjusting unit 40 to adjust the light for capturing the face according to the instruction information, and also receives the electrical signal transmitted by the light adjusting unit 40 to control the light panel unit 30 to adjust the light intensity of the supplementary light source.

[0030] As can be seen from the above, in the device provided in the embodiment, the light panel unit and the light adjusting unit connected with the light control unit by cables are arranged, so that the light control unit can directly control the light panel unit to emit the supplementary light source, and can also receive the adjustment signal of the light adjusting unit to adjust the light intensity of the supplementary light source emitted by the light panel unit, thereby meeting different requirements of the face capturing device for the light source during operation, improving the camera recognition accuracy and operation speed, and avoiding long waiting time of the customer.

Please refer to Figure 9 , Figure 9 is a schematic diagram of the switch relay module signal line. As Figure 9 shown, the switch relay module signal line connects the relay 52 with the master control unit 10 through the interfaces a1 and a1'.

[0043] In use, according to the requirement, the power module direct supply input interface and the relay power supply input interface are selected to be turned on, and it is determined whether the working voltage is output by the relay 52 or the power module 51.
