| 摘要 |
The invention proposes an illumination module ( 10 ) producing an illumination beam with cutoff, comprising, arranged from back to front along a horizontal optical axis (A-A), an elliptical reflector ( 12 ) which delimits a volume of reflection and which has an elliptical surface of reflection ( 18, 20 ), at least one light source ( 14 ) which is arranged in the vicinity of a first focus (F 1 ) of the reflector ( 12 ), and a convergent lens ( 16 ) whose focal plane is arranged in the vicinity of the second focus (F 2 ) of the reflector ( 12 ), characterized in that the reflector ( 12 ) has a horizontal flat surface ( 22 ), the upper face ( 24 ) of which is reflective, which delimits vertically towards the bottom the volume of reflection, and in that the flat surface ( 22 ) of the reflector ( 12 ) has a cutoff edge ( 28 ) which is arranged in the vicinity of the second focus (F 2 ) of the reflector ( 12 ).
