Abstract
PURPOSE:To prevent the incapability of the automatic lighting due to the misoperation of the operation circuit when the periphery becomes dark, by deciding the output time of the operating circuit with the time constant of the differentiating circuit and then giving the control to the illuminator's lighting. CONSTITUTION:The outputs of operating circuit 4 and automatic lighting circuit 1 are supplied to AND circuit 5, and the output of circuit 5 is differentiated 6 to be sent to memory 7. Then load 3 is controlled with the output of memory 7 and via load control circuit 8. In this case, the output time of circuit 4 is decided with the time constant of circuit 6 to give the control to load 3 formed by the illuminator. As a result, the illuminator is lit up automatically when the periphery becomes dark and then turned out when the periphery becomes bright respectively. Thus the illuminator can be freely turned on and off through circuit 4 to prevent the incapability of the automatic lighting due to the misoperation of circuit 4.
