Vehicular lamp

摘要

A vehicular lamp used in a vehicle, includes: a light source for emitting light in accordance with a voltage given thereto; a light-source controlling transistor for controlling power supplied to the light source by repeatedly switching whether or not the power is supplied to the light source; a capacitor having one end grounded and another end at which a potential is changed like a saw-tooth by charging and discharging of the capacitor; a capacitor controlling transistor for controlling a timing at which the charging and discharging of the capacitor is switched; and a comparator for comparing the potential at the other end of the capacitor to a reference voltage given thereto and controlling a timing at which the light-source controlling transistor is turned on or off and a timing at which the capacitor controlling transistor is turned on or off in synchronization with each other based on the comparison result.
