Lighting device for a vehicle

摘要

The lighting device includes a light source (12) and a reflector (10), which is provided with a reflecting surface (16) with a basic shape formed so that light generated by the light source (12) is reflected from the reflecting surface (16) as a light beam with a predetermined characteristic. The reflecting surface is provided with a wave structure superimposed on the basic form and including alternating successive scattering wave sections (32;42) and concentrating wave sections (34; 44). The extent (b) of the scattering wave section (32) perpendicular to the surface lines (33) is substantially larger than the extent (c) of the concentrating wave sections (34) perpendicular to the surface lines (35). Because of the wave structure the light beam reflected by the reflecting surface is scattered and made uniform.
