[0026] The regulating circuit board includes a mains input circuit 3, a driving chip circuit 4 connected to the mains input circuit, a dial regulating circuit 5 connected to the driving chip circuit, and a de-strobing color temperature adjusting circuit 6 connected to the driving chip circuit; when connected, the output end of the de-strobing color temperature adjusting circuit is connected to the DOB light source board, and the dial regulating circuit realizes the dial regulating output voltage, and realizes the power and color temperature adjustment of the DOB light source board after de-strobing by the de-strobing color temperature adjusting circuit. Its mains input circuit includes an input terminal, a regulating circuit connected to the input terminal, a rectifying and filtering circuit connected to the input terminal, and an output regulating circuit, which is mainly used for mains regulation and rectifying and filtering operations; its regulating circuit is specifically composed of two adjustable resistors VR3 and VR4 connected in series in the circuit, and a signal PE terminal is set at the connection point of VR3 and VR4;

[0027] In this embodiment, the dial adjustment circuit includes a first resistor R1, a second resistor R2, a third resistor R3, a fourth resistor R4, a fifth resistor R5, a sixth resistor R6, a seventh resistor R7, an eighth resistor R8 and two capacitors; when connected, the fifth resistor and the sixth resistor are connected in parallel, and one end is connected to the power supply and the other end is connected to the ADIM signal end; the third resistor and the fourth resistor are connected in parallel, and one end is connected to the ADIM signal end and the other end is connected to the second pin of the dial output; the seventh resistor and the eighth resistor are connected in parallel, and one end is connected to the second pin of the dial output and the other end is connected to the first pin of the dial output; the first resistor and the second resistor are connected in parallel, and one end is connected to the first pin of the dial output and the other end is connected to the ground wire; one capacitor is electrically connected between the second pin of the dial output and the ground wire, and the other capacitor is connected between the first pin of the dial output and the ground wire. It realizes the adjustment of the resistance value through the signal control of ADIM, so that the output power and voltage output are different to meet the use requirements of different situations;

[0028] In this embodiment, the de-strobing and color temperature adjustment circuit mainly includes a MOS tube, a voltage regulator diode, and then cooperates with a unidirectional diode and a parallel resistor and capacitor circuit. The purpose of the MOS tube as a switch tube can be achieved through the characteristics of the MOS tube working in the cut-off area and the variable resistance area. The different MOS tubes are made to work in the constant current area through the driving chip circuit, so that the MOS tube is in a saturated state.

Different color temperature adjustments can be achieved by different combinations of three-color lights.
