Apparatus and method for simultaneously adjusting brightness and color temperature, and LED lamp
An apparatus and method for simultaneously adjusting brightness and color temperature, and an LED lamp. The apparatus includes a phase control dimmer, a rectification module, a phase detection module, a current control module and an LED module. Cutting the phase of an input alternating current by the phase control dimmer changes the effective voltage of the alternating current, then the cut alternating current is rectified by the rectification module and output to the LED module, thus adjusting the brightness of the LED module; information about the cut phase is detected by the phase detection module and a current control signal is output to a current control module according to the cut phase information, and the current control module controls change in the brightness ratio of mixed colors of the LED module according to the current control signal and adjusts the color temperature of the LED module.
