VEHICULAR LIGHTING FIXTURE AND DRIVE UNIT FOR THE SAME

摘要

PROBLEM TO BE SOLVED: To provide a vehicular lighting fixture capable of gradually changing an electric current of a light emitting unit, and a drive unit for the same.SOLUTION: A bypass circuit 40, which is provided in parallel with the light emitting unit, can independently switch between an ON-state and an OFF-state. A bypass transistor M1 is provided in parallel with a light emitting unit 12. A feedback capacitor C1 is provided between a gate drain and a gate collector of the bypass transistor M1. A gate drive circuit 60 supplies a drive voltage based on a control signal S1, between gate sources of the bypass transistor M1.
