Dimming and color modulation controller based on input voltage control and method of dimming and color modulation controller

Abstract

The invention relates to a dimming and color modulation controller based on input voltage control and a method of the dimming and color modulation controller. The controller comprises an input unit, a power supply unit, an input voltage detection unit, a master control chip U1, an output unit and a dummy load control unit, wherein the input unit is connected with an LED driving power supply and inputs a voltage to the master control chip U1, the input voltage detection unit is used for detecting an input voltage of the LED driving power supply and inputs to the master control chip U1, the master control chip U1 outputs a signal to control the dummy load control unit so as to indirectly control the output unit, the output unit is connected with a lamp, and the dummy load control unit is used for outputting a signal to control the LED driving power supply to discharge under the control of the master control chip U1. By the controller, the switch-on and switch-off actions of an AC switch of the LED driving power supply are enabled to be accurately judged within the shortest time, switching of color temperature and brightness of an LED can be achieved, the controller is high in flexibility, and the matching of the LED driving power supply and the diming and color modulation controller is convenient.

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...

Problems solved by technology

For the first method, it is highly targeted but lacks flexibility; for the second method, it is flexible but needs to match the LED drive power supply and dimming and color controller to work normally, but the LED drive power supply currently on the market There are so many types, it is extremely difficult to match them well
