Abstract
A light-emitting module including: a laser element; a converting member; a sense wiring; an electric potential determining circuit configured to output a first value when an electric potential at a first end of the sense wiring is in a predetermined range, and to output a second value when the electric potential at the first end of the sense wiring is out of the predetermined range; a first switching element electrically connected in series to the laser element, the first switching element configured to become conductive when the output is the first value, and to become non-conductive when the output is the second value; and a second switching element electrically connected in parallel to a circuit comprising the laser element and the first switching element, the second switching element configured to become conductive when the output is the second value, and to become non-conductive when the output is the first value.
