Abstract
An optical arrangement is provided that includes a first optical element comprising a light guide that has a bevel face and a second optical element. The first optical element conducts light by total internal reflection at a wall and has a light entry area defined by a non-beveled end face and a light exit area formed by a surface area of the wall at that end proximate the bevel face. The second optical element has a light entry aperture arranged on or facing the light exit area. The light entry area has a width x and the light entry aperture has a height z, which meet the following relationship:≤1.5·[tan(90°−α/2)−tan(90°−(2·[α/2+90°]−[180°−arcsin(1/)]))]. Herein, α denotes the deflection angle of the light at the bevel face and n denotes the refractive index of the material of the first optical element.
