Abstract

La lentille optique (10) pour diffuseur de lumière présentant une face arrière (23) destinée à être accolée à une paroi (18) et une face avant destinée à éclairer un lieu. La lentille est symétrique par rapport à un plan et comporte : - une partie (20) présentant une surface arrière concave (21) et une surface avant convexe (27), dite partie supérieure et - une partie (22) présentant une surface arrière plane ou convexe (28) et une surface avant convexe (26), dite partie inférieure. Dans des modes de réalisation, une ligne de points coplanaires de la surface arrière concave (21) où les plans tangents à la surface arrière concave coupent le plan de symétrie selon des axes parallèles entre eux est décalée du côté de partie supérieure, par rapport à une ligne de points coplanaires de la surface avant convexe (26, 27) où les plans tangents à la surface avant convexe coupent le plan de symétrie selon des axes parallèles entre eux.
