Patent ID: 8469570

Claim:
A vehicle head light comprising: a housing formed with an opening at a front end of the housing; a lens cover fixed to the opening to close an internal space of the housing as a light chamber; a light source disposed in the light chamber; and a heat radiating member disposed in the light chamber to radiate heat generated from the light source to the light chamber, wherein the heat radiating member includes: a pillar member provided to extend from a bottom wall of the housing, the light source being mounted on an upper end of the pillar member; heat radiating fins having a plate shape and fixed radially to an outer periphery of the pillar member so as to extend in a longitudinal direction of the pillar member; and a guide wall provided surrounding sides of the heat radiating fins, the guide wall being sloped with respect to the bottom wall of the housing to approach the pillar member with increasing distance from a lower end of the guide wall so that spaces each formed by adjacent two of the heat radiating fins and the guide wall become narrower with increasing distance from the lower end of the guide wall, the guide wall being formed with slits to make air communication between the light chamber and each of the spaces, the slits being shaped to be narrower with increasing distance from the lower end of the guide wall.
