Abstract
A light source unit mounted in a mount portion of a vehicle includes a heat block and a reflector accommodated in an imaginary cylinder that is defined by a holding device for holding an outer circumference of a lens. A first heat dissipating portion and a second heat dissipating portion, which are partitioned by a partition plate, are provided on an outer circumferential surface of the heat block. A plurality of fins are projected on the first heat dissipating portion which is disposed on a lens side of the heat block so as to extend in a circumferential direction, and a second plurality of fins are projected on the second heat dissipating portion so as to extend in an axial direction of the heat block. The partition plate includes a mounting rib, and a mounting device is provided on the mounting rib for mounting the light source unit in the mount portion of the vehicle.
