Zusammenfassung:A light emission driving device includes an output voltage supply unit arranged to generate an output voltage from an input voltage so as to supply the output voltage to a load, a determination unit arranged to determine whether or not a ground fault due to abnormality may have occurred on the basis of an anode voltage of the load, and a signal output unit arranged to externally output a signal indicating that a ground fault due to abnormality may have occurred when the determination unit determines that a ground fault due to abnormality may have occurred. The output voltage supply unit does not perform generation stop of the output voltage by a trigger of determination by the determination unit that a ground fault due to abnormality may have occurred.
