When the drain and source of the fet Q1 are turned on (if the gate of the Q1 has a level signal to control its turn on), the voltage at the drain of the Q1 goes through the LED + to the LED through the LED lighting circuit 75 (for the LED module), and then goes through the current sense resistor R9 back to the negative terminal of the battery, which turns on the flashlight. When the flashlight is in a lighting state, the side key is pressed for a long time, the port RA3 of the first singlechip processor 72 (U4 in fig. 6) receives a low level signal for a long time, internal processing is performed, different PWM signals are output from the port RA4, the PWM signals are input to the reverse end of the operational amplifier TLV333 and compared with the voltage detected by the detection resistor R9(0.02 ohm), the operational amplifier TLV333 outputs a control level signal to the grid of the Q1, the frequency of the PWM signals determines the frequency of the control level signal to the grid of the Q1, and the effective voltage value passing through the LED lighting circuit 75 is indirectly controlled, so that different brightness is output, and the function of adjusting the brightness of the flashlight is achieved. In addition, as shown in fig. 7, it is a schematic circuit diagram of the linear voltage-reducing circuit 76, which mainly provides a stable operating voltage of 2.5V for the circuit of the first mcu 72 shown in fig. 6.
