Light-emitting device for intelligent closestool

The utility model discloses a light-emitting device for an intelligent closestool. A DC/DC power supply module is connected with a slide rheostat module through a photoresistor RG to form a series loop; when the intensity of the ambient light becomes weak from strong; the resistance value of the photoresistor RG is correspondingly increased from small to large; therefore, the potential of the sliding variable resistance connecting end of the sliding rheostat module is changed; according to the scheme, the process is detected through the voltage comparator module; then the signals are sent to acontroller through a signal conversion module; the controller can output control signals with different pulse widths to the controlled switch module according to the detected ambient light intensitychange condition; therefore, the LED light-emitting module can be controlled to emit light weakly or not when the ambient light is strong, the LED light-emitting module can be controlled to emit lightgradually when the ambient
