Abstract

The present invention relates to a dimming and toning controller based on input voltage control and a method thereof. The controller includes an input unit, a power supply unit, an input voltage detection unit, a main control chip U1, an output unit and a dummy load control unit; an input unit, which Connect with the LED drive power supply, input voltage to the main control chip U1; input voltage detection unit, which detects the input voltage of the LED drive power supply, and input it to the main control chip U1, and the dummy load control unit is controlled by the output signal of the main control chip U1 to The indirect control output unit; the output unit is connected with the lamp; the dummy load control unit, under the control of the main control chip U1, outputs signals to control the LED drive power supply to discharge. The invention ensures that the light-off action of the AC switch of the LED driving power can be accurately judged in the shortest time, can realize the color temperature and brightness switching of the LED, has good flexibility, and is convenient for matching the LED driving power and the dimming and coloring controller.

Description

technical field [0001] The present invention relates to the technical field of light-adjusting and color-adjusting controllers, in particular to a light-adjusting and color-adjusting controller based on input voltage control and a method thereof. Background technique [0002] With the popularization of smart homes, the intelligence of LED lamps has attracted more and more attention. The intelligence of LED lamps is embodied in the process of dimming and color adjustment, and the dimming and color adjustment of LED lamps is mainly composed The color controller is complete. [0003] At present, the popular dimming and coloring controllers on the market are mainly button, touch or infrared sensor control methods, which can basically meet the needs of some lamps for dimming and coloring functions. However, many types of lamps, such as ceiling lamps, bread lamps and other lamps that are far away from users, cannot be controlled by touch or induction. Ideal means. There are two...
