Vehicular headlight reflector suitable for use with a discharge lamp |
摘要 |
A reflecting surface consists of three reflecting sectors arranged around the optical axis. The first reflecting sector located above the horizontal plane including the optical axis is a part of a paraboloid of revolution having a focus at point F. The second reflecting sector consists of two sub-sectors located on the right and left sides of the vertical plane including the optical axis. A fundamental surface of the two sub-sectors has a reference parabola in a plane inclined from the horizontal plane by a predetermined angle, and is a collection of intersecting lines each obtained by cutting an imaginary paraboloid of revolution assumed for a point on an orthogonal projection of the reference parabola onto the horizontal plane by a vertical plane including an axis of the imaginary paraboloid of revolution. The third reflecting sector located below the horizontal plane is a part of a paraboloid of revolution having a focus at point G. An orthogonal projection of an arc of a discharge lamp is located between points F and G.
