Abstract

The optical element has the shape of a wedge 15 of transparent material, which receives light from outside through the end surface 14 of the wedge. The transparent material has an index of refraction n. At the top 19 of the wedge 15 there is a layer 16 of transparent material with an index of refraction smaller than the index of refraction n of the wedge 15, and on the outside of the transparent layer 16 there is a light-directing layer 17. The light-directing outer layer 17 can consist of a coat of white paint or be constituted with prisms which are mirror-coated on their outer surfaces facing away from the wedge 15. With this optical element, one achieves an approximately parallel-directed antiglare illumination from the bottom 18 of the wedge 15. <IMAGE>
