摘要： A device includes light source and a controller. The light source includes a first LED coupled to a second LED, where a first terminal of the first LED is coupled to a first terminal of the second LED. The controller is configured to receive an input signal indicative of a color of light. The controller is also configured to adjust, based on the input signal, a first proportion of a current, the first proportion being applied to the first LED. The controller is also configured to adjust, based on the input signal, a second proportion of the current, the second proportion being applied to the second LED.
