  • Illumination power circuit with dimming function and associated control method
    Patent number: 11612025
    Abstract: An illumination power circuit with a dimming function and an associated control method thereof are provided, where the illumination power circuit includes a first conversion circuit, a digital controller and a second conversion circuit. The first conversion circuit converts a first analog dimming signal from an analog dimmer into a first digital dimming signal, where the analog dimmer generates the first analog dimming signal according to operations of a user, to allow the user to manually control brightness of an illumination device. The digital controller receives the first digital dimming signal and a control signal from a computer, and generates at least one final dimming signal according to the first digital dimming signal and the control signal. In addition, the second conversion circuit generates a direct current output signal according to the final dimming signal, for driving the illumination device.
