[0027] The principle is as follows: connect the power supply, the output LED light is on, and the button K2 on the shell is pressed to turn on. K2 receives a ground signal and sends it to the 6th pin of the program chip U2. Through internal processing, a high level is generated from the 5th pin of U2, coupled through R14, and divided by R13 to obtain a stable high level, which switches on the Q2 transistor to turn on the LED light. Then, press K2 to turn off. Through chip processing, a low level is generated from the 5th pin of U2, so that the Q2 transistor is cut off and the LED1 light is turned off. Then, press K2 for a long time for 3 seconds, and the 4th pin of the program chip U2 generates a low level, the LED indicator light is on, and the timing starts (6 hours on and 18 hours off, cycle every day, except AC power failure). The program chip will restart the power supply and reset it), and then K1 is pressed to adjust the brightness in sections (100%-75%-50%-25%). K1 receives a ground signal and sends it to the 7th pin of the program chip U2. Through internal processing, a PWM signal is generated from the 5th pin of U2, and Q2 is turned on and off through R14 and R13, and different brightness (100%-75%-50%-25%) is generated from the LED1 lamp. K1 is long pressed to make the program chip output a control signal to make Q2 turn on to different degrees (LED1 becomes brighter or darker). C7, C8, and Y1 form a timing frequency oscillation to make the timing more accurate. R12, ZD1, and C6 form a voltage stabilizing circuit to provide stable power supply to U2.
