MOTOR-VEHICLE LIGHT

A motor vehicle light, in particular a reversing light, has an intermediate glass (4) between its incandescent lamp and the lamp glass. Illumination from the lamp is reflected in a parallel beam falling on an alternating pattern of convex surfaces (5) and V-grooves (6) on the inner face of the intermediate glass. The outer face of the glass is in the form of a screen having light passages (8) separated by light-impermeable surfaces (7). Optically effective surfaces (9) of the light passages are in alternation to each other inclined in opposite directions to the axis of the beam. The light passages are directly opposite the convex surfaces of the inner face. The V-groove surfaces deflect the light through them onto the front face light passages. In this manner, an effective distribution of illumination can be achieved from the vehicle light.

AUTOMOTIVE HEADLAMP HAVING REDUCED CHROMATIC ABERRATION

The present invention relates to an automotive headlamp construction in which chromatic aberation is substantially eliminated. The headlamp includes an elliptic reflector, a light source disposed at a first focal point of the elliptic reflector, a condenser lens which is focused generally at a second focal point of the elliptic reflector, and an outer lens provided in front of the condenser lens. In accordance with the invention, the radius of curvature of the outer lens is reduced at a vertically middle portion thereof to form an angled portion through which light from the light source passes. The angled portion acts as a lens having a focal length such that chromatic aberration of the condenser lens is canceled out.
