[0038] It should be added that the control circuit includes LDO voltage regulator circuit, MCU circuit, OLED screen circuit, linkage shaft circuit, LED+MOS tube control circuit, and button SW1;

[0039] The LDO voltage regulator circuit is composed of U2, C5, and C6. C5 and C6 are connected to the 3 and 2 pins of U2 respectively. U2 is a 2.8V voltage regulator IC, and C5 and C6 are filter components.

[0040] The MCU circuit consists of U1 and C7. U1 is a single-chip microcomputer. C7 is connected between pins 3 and 5 of U1. Pin 2 of U2 is connected to pin 3 of U1. The button SW1 is connected to pin 10 of U1.

U1 determines the current angle between the lamp body and the lamp holder by detecting the voltage on the shaft. The angle between the lamp body and the lamp holder is 090 degrees, and the voltage point corresponding to the shaft output is 02.8V. When the lamp body and the lamp holder are combined at 0 degrees, the voltage detected by U1 is 0V. At this time, the button is pressed, Q1 is low level, Q1 is turned off, the LED is not lit, and Q2_EN of the OLED display circuit is high level, so that U3 is also turned on, 2.8V supplies power to the OLED, and then communicates with the OLED screen IIC through the MCU to realize lighting and display the lock key icon. When the angle between the lamp body and the lamp holder is greater than or equal to 60 degrees, the voltage detected by U1 is greater than or equal to 1.86V. At this time, the button is pressed, Q1 is at a high level, Q1 is turned on, and the LED lights up. At the same time, Q2_EN of the circuit is turned on at a high level, so that U3 is also turned on, and 2.8V is supplied to the OLED. Then, the MCU communicates with the OLED screen IIC to realize lighting and display the corresponding gear position and LED brightness. In this way, the lighting conditions can be set to prevent accidental touch when carrying the lamp.
