LIGHTING DEVICE HAVING A SMOOTH CUT-OFF |
摘要 |
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. |
