| 摘要 |
The central reflector (221) has two parabolic subsections (221a,221b) producing beams parallel to the vehicle's longitudinal axis (X1-X1), slightly tilted downward (e.g. 4deg). A wing section (222), connected to one subsection (221a) by a step(225) not itself receiving direct light, has a beam axis (X2-X2) laterally offset (a2) 25degree. A corresponding wing (223) on the other subsection (221b), requiring no step because of the front-glass geometry, has its beam axis (X3-X3) offset 40 degree (a3) to the other side. A further extension (224), having a 35degree (a4) offset beam, is connected to this wing by another step (226) receiving no direct light. All sections have a common focus(F).
