ことを特徴とする照明回路。A DC power supply, a photoconductive element whose resistance value changes depending on the strength of light, a monostable multivibrator that is triggered when the resistance of the photoconductive element becomes high, and an output when the resistance of the photoconductive element becomes high. It consists of a logic circuit that inverts, a switching circuit that is controlled by the logic circuit and the output of the monostable multivibrator, and a light bulb that turns on or off depending on the on/off of the switching circuit, and the light remains constant only when it becomes instantly dark. A lighting circuit characterized by lighting a light bulb for only a certain amount of time.
