Abstract
An auto-adjusting light system includes an inputting sub-circuit, a photosensitive sub-circuit, a controlling sub-circuit, a starting sub-circuit, and a display. The inputting sub-circuit is used to input a setting value. The photosensitive sub-circuit is used to catch variations of the light source in the background. The controlling sub-circuit is coupled with the inputting sub-circuit and the photosensitive sub-circuit to receive the setting value and the variation value and generates a controlling signal. The starting sub-circuit is coupled with the controlling sub-circuit to receive the controlling signal and generates a starting voltage. The display is coupled with the starting sub-circuit to receive the starting voltage lightening the display.
