出力を出す回路とからなる放電灯点灯検出装置。A discrimination circuit which receives the voltage applied to the discharge lamp as an input and outputs an output when it discriminates that the voltage is higher than a voltage corresponding to a voltage lower than the lamp voltage of the discharge lamp, and after the lighting power source is turned on, Until the voltage applied to the discharge lamp once becomes higher than the lamp voltage, the discharge lamp is in a lighting state due to the delay circuit that disables the discrimination circuit and the output of the discrimination circuit. A discharge lamp lighting detection device consisting of an output circuit.
