式自動点滅器。[Scope of Claim for Utility Model Registration] (1) A light-receiving element that detects ambient illuminance, a capacitor that prevents the output of this light-receiving element from fluctuating due to instantaneous changes in ambient illuminance, and a voltage across the capacitor. A control circuit detects that the ambient illuminance has reached a predetermined illuminance at which the lighting load is turned on or off by comparing it with a reference voltage using a comparison means, and controls the lighting of the lighting load. A photoelectric automatic flasher characterized in that it comprises a holding means for holding the control circuit output in the state before an instantaneous power outage or an instantaneous voltage fluctuation occurs when a fluctuation in the power supply voltage occurs. (2) A capacitor is installed in the comparison means so that the rate of decrease in the reference voltage of the comparison means of the control circuit when an instantaneous power outage or instantaneous voltage fluctuation occurs is slower than the rate of decrease of the voltage across the capacitor that prevents the output fluctuation of the light receiving element. The photoelectric automatic flasher according to claim 1, characterized in that it is provided in a reference voltage input section. (3) A capacitor is installed in the comparison means so that the rate of decrease in the output voltage of the comparison means of the control circuit when an instantaneous power outage or instantaneous voltage fluctuation occurs is slower than the rate of decrease in the voltage across the capacitor that prevents the output fluctuation of the light receiving element. The photoelectric automatic flasher according to claim 1, characterized in that it is provided in a reference voltage output section.
