Abstract:
1. A color temperature controller of a light emitting diode (LED), applied in a light emitting diode (LED) lamp, and the color temperature controller comprising: a plurality of touch switches, each having a color pattern, provided for a user to select any one color from the color patterns, such that signals of the colors are outputted through the touch switches; a control element, for receiving the signals of the colors outputted by the touch switches, and outputting a corresponding PWM signal according to the signals of the colors to control either a current or a voltage of a three-color LED in the LED lamp, such that the LED lamp produces a same color temperature change of the signals of the colors; and a power supply device, for supplying an electric power required by related electronic components of the color temperature controller.
