ABSTRACT:
An improved vehicle headlamp for developing forward illumination and having reduced dimensions relative to prior art headlamps is disclosed. The lamp comprises an enclosed concave parabolic reflector of a rectangular cross section type and having a single tungsten-halogen light source coaxially located within the enclosed reflector. The headlamp has a glare shield arranged around the light source when the headlamp is utilized for low beam application and a heat shield located about the light source for both low and high beam applications. The light source is of a tubular shape and has a bulbous portion preferably of an ellipsoidal shape. The efficacy of the light source is improved by means of an infrared reflective coating placed on its outer surface.
