Dimming and color temperature adjusting control device

A dimming and color temperature adjusting control device, comprising a housing, a control panel, and a control circuit board;

• the control circuit board is arranged in the housing, and the control circuit board is provided with a zero-crossing detection circuit, a control circuit, a carrier phase-cutting circuit and a power supply circuit;
• the zero-crossing detection circuit is used for detecting a zero-crossing point position of mains;
• the control circuit is electrically connected to an output end of the zero-crossing detection circuit and is used for calculating a chopping position according to a brightness adjustment amount and the zero-crossing point position, and encoding a color temperature adjustment amount to generate a color temperature encoding signal;
• the carrier phase-cutting circuit is electrically connected to an output end of the control circuit and is used for chopping mains according to the chopping position to generate a phase-cut dimming signal, and carrying the color temperature encoding signal on the phase-cut dimming signal;
• the power supply circuit is used for supplying power to the zero-crossing detection circuit, the control circuit and the carrier phase-cutting circuit;
• the control panel is arranged on the housing, and the control panel is provided with a brightness operation module and a color temperature operation module;
• the brightness operation module is electrically connected to the control circuit and is used for inputting the brightness adjustment amount;
• and
• the color temperature operation module is electrically connected to the control circuit and is used for inputting the color temperature adjustment amount.
