[0020] In this invention, the microcontroller module is connected to each LED load via a totem-pole circuit, such as... Figure 7 As shown, four sets of totem pole driving transistors Q5+Q6+Q7, Q8+Q9+Q10, Q11+Q12+Q13, Q14+Q15+Q16 drive MOSFETs Q1-Q4.

The output control section utilizes a totem-pole circuit composed of three transistors to control the operation of the 9V drive MOSFETs with a 5V control signal, significantly reducing drive current loss. Drive MOSFETs Q1-Q4 control four groups of LEDs on the LED board: low color temperature with small angle, low color temperature with large angle, high color temperature with small angle, and high color temperature with large angle, respectively. The LEDs are switched on and off based on the PWM signal output from the MCU. Different light mixing results are achieved by varying the on / off ratios of all low and high color temperature LEDs, allowing for any color temperature within the range of 3000K-6500K according to customer requirements.
