Control system for color temperature regulation of led lights

Abstract

The present invention discloses a control system for color temperature regulation of LED lights, comprising an AC input and a rectifying circuit. The rectifying circuit is connected with an absorption circuit; the absorption circuit is connected with a current regulation control module; a detection circuit is disposed between the current regulation control module and the absorption circuit; the current regulation control module is connected with a cold color series LED light module and a warm color series LED light module in parallel; and the cold color series LED light module and the warm color series LED light module generate a voltage difference. According to the present invention, through the configuration where the cold color series LEDs and the warm color series LEDs generate different voltages at different currents, the cold color series LED light module and the warm color series LED light module generate different voltage drops at different currents by means of the arrangement of resistors, achieving the effects of changing color temperature and regulating light. The process of the color temperature change is natural and smooth, enhancing visual comfortableness for users. Meanwhile, the control system for color temperature regulation of LED lights has a simple structure and is low in cost.
