Abstract
A vehicle headlamp assembly including a housing case and a lens cover forming a light chamber, a projection lens, a shade and a light source are arranged within the light chamber in that order along an optical axis of the headlamp assembly. A radiating member includes plate-shaped radiating fins vertically placed in the light chamber, for radiating heat energy generated by the light source to surrounding air. A plate is arranged at a right angle to the radiating fins in the light chamber, for controlling air-convection flow around the radiating fins.
