A light source module (100) is capable of switching between high beam and low beam, and is mounted on a vehicle. The first light source (110) is configured so as to irradiate the low-beam region (12) with the emitted light thereof through the first optical system (4). The second light source (120) is configured so as to irradiate the high beam region (14) with the emitted light thereof through the second optical system (6). The lighting circuit (130) supplies a drive current (IOUT) to the first light source (110) in response to a lighting instruction of either the high beam or the low beam, and supplies a drive current (IOUT) to the second light source (120) in response to a lighting instruction of the high beam.

    光源模块(100)能够切换远光和近光,被搭载于车辆。第一光源(110)被配置为通过第一光学系统(4)向近光区域(12)照射其出射光。第二光源(120)被配置为通过第二光学系统(6)向远光区域(14)照射其出射光。点灯电路(130)响应于远光、近光任一者的亮灯指示,向第一光源(110)供给驱动电流(IOUT),同时响应于远光的亮灯指示,向第二光源(120)供给驱动电流(IOUT)。
