At this time, the path of the current output by the power supply unit 3 flowing through the resistance adjustment unit 9 is shortened, and the resistance adjustment unit 9 is turned off. 9 decreases, so that the current flowing through the lamp body 1 increases, thereby enhancing the lighting intensity of the lamp body 1. When the external light intensity increases, the control unit 8 receives the light intensity enhancement signal to issue an operation instruction to the driving unit 5, and uses the driving unit 5 to drive the conductive part 4 to move to the other side along the resistance adjusting unit 9. At this time, the path of the current output by the power supply unit 3 flowing through the resistance adjusting unit 9 is extended, and the resistance of the resistance adjusting unit 9 increases, so that the current flowing through the lamp body 1 decreases, thereby reducing the lighting intensity of the lamp body 1, so as to realize automatic adjustment of the lighting intensity of the lamp body 1.

When the conductive rod 55 rotates forward, it can cooperate with the thread of the conductive sleeve 43 to drive the conductive sleeve 43 and the conductive card 44 to move to one side along the insulating member 91, so that the path of the current output by the power supply unit 3 flowing through the resistance adjustment unit 9 is shortened, the resistance value of the resistance adjustment unit 9 is reduced, and the current flowing through the lamp body 1 is increased, thereby enhancing the lighting intensity of the lamp body 1; when the intensity of external light increases, the driving unit 5 can drive the conductive rod 55 to rotate reversely according to relevant instructions.

When the intensity of external light is weakened, the control unit 8 receives the light intensity weakening signal to issue an operation instruction to the driving unit 5, and uses the driving unit 5 to drive the conductive part 4 to move to one side along the resistance adjusting part 9.
