Abstract (en)
[origin: EP1978298A2] The reflector (7) has a reflection surface (8) with a series of segments (9), which are distributed in a circumferential direction of a reflector axis (10) with a certain angle (alpha) in the circle. The segments are arranged in a longitudinal direction of the reflector axis with different lengths (L1, L2) and angles. The shape of each segment corresponds to a spherical trapezoid, and all segments have same radius and are inwardly curved in the circumferential direction of the reflector axis.
