| Abstract: | Lighting system with constant luminance has a good prospect in some large rooms such as library and museum. Based on photosensitive resistor, an Automatic dimming system of the fluorescent lamps was established. The system has the function of regulating the lamp power when the environment illumination was changed. The automatic dimming system circuit diagram was introduced including the detecting circuit, the dimming circuit and so on. The Pspice model of the photosensitive resistor, fluorescent lamps model and dimming theory were also discussed. Verified by the simulated results, the system does have the function of changing the lamp power automatically. |
