METHOD OF FORMING DIRECTIONAL PATTERN OF VEHICLE LIGHTING DEVICES Russian patent published in 1997 - IPC

Abstract RU 2094256 C1

FIELD: lighting engineering. SUBSTANCE: directional pattern is formed by scanning with light beam at frequency exceeding or equal to 30 Hz which is human eyes' persistence of vision. This makes it possible to reduce power of light source, to form any directional patterns in dynamic mode, change over from low to high beam, form Z-shaped light boundary illuminate objects on road side and stabilize light flow relative to road. EFFECT: enhanced reliability. 2 dwg
