DIRECTIONAL RADIATION FACILITY Russian patent published in 2003 - IPC

FIELD: optical instrumentation, lighting engineering devices for vehicles. SUBSTANCE: directional radiation facility includes light source located at butt of light guide. Light guide comes in the form of wedge with transmitting and reflecting microreliefs on its surface. Output transmitting microrelief can be manufactured in the form of raster of focusing lenses or raster of diverging lenses or raster of crossing lenses. Reflecting microrelief can be fabricated in the form of raster of quasi-diffraction prisms. Technical result of invention consists in reduced power of light source, in improved maintainability of facility, in provision for formation of various directional patterns, for example, Z-shaped light boundary to diminish dazzling of drivers coming from opposite direction, reduced overall dimensions. EFFECT: improved functional characteristics of facility. 5 cl, 4 dwg
