The DIM signal received by the conversion socket terminal J3 is output to the main control unit U4 after voltage division. After receiving the DIM signal, the main control unit U4 sends it to the driving unit U1-2.

[0027] It also includes a display screen terminal J7 connected to the main control unit U4 for displaying control content.

[0039] The specific working principle of this application is as follows:

[0040] The controller has five buttons, KEY1-5 in the circuit, corresponding to the up, down, left, right and OK buttons respectively. The buttons send signals to the main control unit U4 to control the adjustment of the output DIM signal percentage, thereby dimming different lamps.

[0041] The conversion socket terminal J3 divides the received SIG IN1-3 signals through resistors R1, R10, R11, R2, and R3, R12, and enters the 28, 27, and 26 pins of the main control unit U4 respectively, and displays the percentage of the current input signal through the LCD display;

[0042] The 3-way 3.3V PWM signal output by the main control unit U4 enters the 2nd and 4th feet of the driving unit U1 and the 2nd foot of the driving unit U2 respectively. Through the level conversion and drive enhancement of the driving unit U1 and the driving unit U2, the PWM signal is converted into a 12V DIM signal with a driving capacity of 50mA, which is respectively passed through the over-current protection of F2, F3, and F4, and finally output to the lamp;

[0043] In addition, the diodes D2, D3, D4, D5, D6, and D7 of the present application are level clamping protection circuits for three output signals, and the diodes D8, D9, D10, D11, D12, and D13 are level clamping protection circuits for three input signals;

[0044] Furthermore, U3 is a clock chip, which cooperates with U4 and J7 to display the time. BC1 is a Farad capacitor as a backup power supply for the real-time clock chip U3 to ensure that the clock continues to run after the 12V power supply is disconnected.

[0045] The above description is only a preferred embodiment of the present application and is not intended to limit the scope of implementation of the present application. Other principles and basic structures that are the same or similar to those of the present application are within the protection scope of the present application.
