Abstract

FIELD: transport; electrical equipment. SUBSTANCE: projector type headlight has concave reflector of complex shape in form of combination of mating sectors of ellipsoid with position of first focus common for all meridional sections and common vertex, with surfaces being described by the following equation. It has also light source with cylindrical luminous element, screen either partially transmitting the light, or lighting with reflected light. Shape of screen edge defines shape of light spot boundary of headlight beam. Headlight has biconvex lens forming screen image in outer space and headlight beam. EFFECT: enlarged operating capabilities.
