Abstract
A lighting device (,) for arrangement on the external or internal rear view mirror of a motor vehicle is provided with a light source (,), the light rays of which emerge at a mirror housing opening and are deflected at a transparent light refraction element (,) arranged in the beam path. The plate-like light refraction element (,) has, at least on one side, a surface structure (,) by means of which the light refraction element is divided into several light refraction zones. To achieve a deflection of the light into a preferred direction the light refraction element (,) is designed in the manner of a Fresnel prism (,), the light refraction zones corresponding to prism zones of a prism body which are pushed together in stepwise manner. To intensify the deflection of the light beam into the preferred direction a decentralized condenser lens (,) may be arranged in front of the Fresnel prism (,).
