[0016] Refer to Figure 1 , this embodiment provides a control circuit for switching color temperature and wall-controlled dimming and color mixing by using an MCU and a toggle switch, including: a dimming and color mixing circuit, an MCU detection and control circuit, an LED light source, and a toggle switch control circuit;
[0017] The MCU detection and control circuit outputs a first control signal and a second control signal to the dimming and color mixing circuit to adjust the brightness of the LED light source and switch the color temperature of the LED light source;
[0018] The toggle switch control circuit is used to output different I / O1 voltages to the MCU detection and control circuit, so that the MCU detection and control circuit correspondingly outputs first control signals and second control signals with different duty cycles, or enables the MCU detection and control circuit to detect the state of the wall switch and output the first control signals and second control signals with corresponding duty cycles to achieve dimming and color mixing of the wall switch.
[0019] Specifically, in this embodiment, the toggle switch control circuit has four gears. When the toggle switch is toggled to the 1st gear, 2nd gear, and 3rd gear, the MCU detection and control circuit correspondingly outputs first control signals and second control signals with different duty cycles;
[0020] When the toggle switch is toggled to the 4th gear, the MCU detection and control circuit detects the state of the wall switch and outputs the first control signals and second control signals with corresponding duty cycles to achieve dimming and color mixing of the wall switch.
[0021] To achieve the above effects, the toggle switch control circuit includes a toggle switch S1, resistors R1, R2, R3, R4, and R5; the 3rd pin of the toggle switch is connected to R1 and connected to VCC; the resistors R2, R3, R4, and R5 are respectively connected between the 1st pin, 2nd pin, 4th pin, 5th pin and GND.
[0022] When the toggle switch is toggled to the 1st gear, 2nd gear, and 3rd gear in sequence, due to different resistor values, the corresponding voltage values of the output I / O1 voltages are V1, V2, and V3 respectively. At this time, the MCU outputs corresponding different PWM1 and PWM2 to achieve three groups of different color temperatures and brightness;
[0023] When the toggle switch is toggled to the 4th gear in sequence, the corresponding voltage value is V4. At this time, the MCU detection circuit detects the state of the wall switch and outputs specific PWM1 and PWM2 to achieve dimming and color mixing of the wall switch;
[0024] The above process realizes the switching between conventional multiple color temperatures and the function of completely controlling the wall switch by toggling one of the gears as the toggle switch's gear is switched.
[0025] The above is only a preferred specific embodiment of the present invention, but the design concept of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention who makes non-substantive modifications to the present invention using this concept shall fall within the scope of infringement of the present invention.
