Abstract:
A drive circuit is configured to drive a light emitting unit which is provided in a vehicle lamp and includes a plurality of semiconductor light emitting elements connected in series. The drive circuit includes a drive voltage generation unit configured to reduce an input voltage from a battery to generate a drive voltage for driving the semiconductor light emitting elements, and a control unit configured to perform ON/OFF control for a bypass switch connected in parallel to a part of the semiconductor light emitting elements and to perform interlock dimming control when the input voltage becomes a first threshold value or lower. The interlock dimming control selects a dimming mode and increases an ON ratio per unit time of the bypass switch as the input voltage drops in the dimming mode.

Claim (Index 4):
The drive circuit according to  claim 1 wherein the vehicle lamp is a variable light distribution type vehicle lamp which includes a movable reflector having a reflecting surface for reflecting light emitted from the light emitting unit and configured to change a direction of the reflected light from the reflecting surface according to an operation position to change a light distribution pattern, wherein a bypass switch is connected in parallel to each of the plurality of the semiconductor light emitting elements in the light emitting unit, and wherein the control unit is configured to perform the interlock dimming control during a period in which a turning-on instruction signal input for light distribution control instructs turning-on of the semiconductor light emitting elements.
