Abstract
An exemplary light source device () includes a power supply (), a light source (), and a photodetector (). The photodetector includes a light sensor () and a resistor () connected in parallel. The power supply, the light source, and the photodetector are connected in series. When the intensity of ambient light increases, a resistance of the light sensor decreases so as to increase a light intensity of the light source. When the intensity of ambient light decreases, the resistance of the light sensor increases so as to decrease the light intensity of the light source.
