A headlamp for vehicles has a lens and a parabolic reflector which are made of synthetic resin and which are joined together by heat. A composite, light scattering reflector for scattering or spreading the light to be concentrated to the upper and central portion of the lens to an extend that no glare is generated, is arranged at the upper and central portion of the parabolic reflector. The composite reflector may be integrally formed with the main parabolic reflector, or may be a separate element joined to the main parabolic reflector.

Headlamp for vehicles

A vehicle lamp device comprises one thin board-like substrate having an aperture for communicating air from inside the lamp device to the outside of the lamp device, and another thin board-like substrate having a port for air communication. The two substrates are closely adjacent each other and define an air passage therebetween. The air passage is filled with desiccants and communicates air with the interior of the lamp device. The two substrates are located and mounted within the range of receiving sufficient heat from a bulb mounted to a resin reflector.

Vehicle lamp device

In an automotive head lamp, an auxiliary reflector made of heat-resisting synthetic resin is integrally provided in the center portion of a reflector made of synthetic resin. The heat-resistant auxiliary reflector encircles the bulb.

Head lamp for automobiles

The present invention provides a headlamp for a vehicle wherein a reflector is different in focal position of a paraboloidal surface between an upper surface and a lower surface thereof, a focal point on the lower surface side is formed to be positioned forwardly more than a length of a sub-filament from a focal point on the upper surface side, and the sub-filament is positioned between both the focal points to thereby efficiently utilize luminescense and obtain a light distribution pattern of high luminous intensity.
