ANTIDAZZLING LIGHT Russian patent published in 2003 - IPC

FIELD: automotive industry. SUBSTANCE: proposed light has light source placed in focus of reflector shaped as paraboloid of revolution. Flux of parallel beams coming from reflector is then reflected from stack of planar relatively parallel plates of optically transparent glass with plate thickness and air gaps between them being much greater than wavelengths of visible light; then linearly polarized reflected light flux is used for illuminating roadbed. Reflector is built integral with light source for turning relative to vertical or horizontal axis and is locked in lower beam position when flux of parallel beams is reflected from stack of plates or in upper beam position when flux of parallel beams is passed directly to road. EFFECT: enhanced safety of vehicle in darkness due to reduced dazzling of drivers by oncoming traffic. 3 cl, 3 dwg
