Abstract

PURPOSE:To negate hysteresis when load goes out so as to decrease power consumption by mounting a thermistor on the exciting coil of a relay so as to sense temperature rise at the time of excitement and changing branched voltage to a photoelectric converting element and varying the action illuminance of a relay. CONSTITUTION:A thermistor 14 is mounted on the exciting coil of a relay 23 so as to sense temperature rise at the time of excitement of a relay 23, and branched voltage to a photoelectric converting element 24 is changed so as to vary the action illuminance of the relay 23. In this way, the temperature change of a relay coil by current application or non-application to the relay coil is converted into resistance change by the thermistor 14 and returned to the base voltage of a transistor 21. Hereby, after illumination light of load goes out, the effect of reverse hysteresis which cancels positive hysteresis gradually appears, and lighting time is shortened and energy saving effect can be obtained.
