    • The invention relates to a lighting device comprising: -at least one light source (11); -a reflective member (20) comprising a reflective surface (22) and an edge (21) ("first edge") forming a light cut-off of light rays passing in a region adjacent to this first edge (21); -a light -modifying member (30) adapted to modify lighting feature (s) of light rays and having an edge ("second edge"). The light -modifying member (30) extends from the reflective member (20) to this second edge (31) over a surface area defined to receive a part of the light rays passing in said region. The second edge is designed such that, among said part of light rays, the light -modifying member (30) modifies proportionally more light rays passing proximate the first edge than light rays passing less proximate the first edge (21). The invention relates also to said light -modifying member (30) per se.
    • 本发明涉及一种照明装置,包括: - 至少一个光源(11); - 反射构件(20),包括反射表面(22)和形成通过在与所述第一边缘(21)相邻的区域中的光线的遮光物的边缘(“第一边缘”); - 适于修改光线的照明特征并具有边缘(“第二边缘”)的光修改构件(30)。 所述光改性构件(30)从所述反射构件(20)延伸到所述第二边缘(31)的限定为接收通过所述区域的一部分光线的表面区域。 第二边缘被设计成使得在光线的所述部分中,光修正构件(30)比通过第一边缘(21)更靠近的光线成比例地修改越过第一边缘的更多的光线。 本发明还涉及所述光改性构件(30)本身。
