Abstract
A single button color-adjustable and dimmable LED lighting device includes a control board, a button knob assembly, and a light-emitting module. The control board has an MCU control circuit having a variable resistor and a switch. The button knob switch is disposed on the control board and electrically connected to the MCU control circuit. The light-emitting module has a first pulse-width modulation (PWM) control constant current circuit, a second PWM control constant current circuit, a first LED, and a second LED. The MCU control circuit is configured to generate two corresponding PWM signals based on the resistance value of the variable resistor and the state of the switch to respectively control an output current for the first LED and an output current for the second LED, such that the light-emitting module emits light with different brightness or different color temperatures.
