装置。[Claims for Utility Model Registration] An oscillator circuit that changes the on/off duty ratio using the input voltage from a resistive rheostat light control or a variable resistor, and an on/off switch that changes the on/off duty ratio using the output from the oscillation circuit. a drive circuit having an output transistor, a dimming lamp that is turned on by the drive circuit, detecting a current when the lamp is in a short state, and turning off the output transistor of the drive circuit by the detection output. Consisting of a detection circuit, and a timer circuit that determines the time to hold the output transistor of the drive circuit in the off state when the detection circuit detects shorting of the lamp, and turns the output transistor on again after the elapse of the time period. A light control device characterized by:
