Headlight for in-vehicle use

摘要

In a headlight for in-vehicle use, an LED serving as an optical source is provided in which one edge side of its light-emitting face is formed into a linear portion and placed at a side of an optical axis so that the center of the light-emitting face is displaced from the optical axis. A projection lens is constituted by a radiation-side convex lens and an LED-side convex lens that are arranged in a direction of the optical axis. Between the LED and the projection lens, a light distribution member is placed that is formed using a transparent material and has, on its inner surface, a reflection face for reflecting light emitted by the LED.

主权项

1. A projector-type headlight for in-vehicle use that radiates light emitted by an optical source, ahead of a vehicle using a projection lens, comprising:
an LED (light Emitting Diode) that constitutes the optical source and has a light-emitting face whose one edge side is linearly formed and placed at a side of an optical axis so that a center of the light-emitting face is displaced from the optical axis; two convex lenses that are arranged in a direction of the optical axis to constitute the projection lens; and a light distribution member that is placed between the LED and the projection lens, that is formed using a transparent material and that has, on its inner surface, a reflection face for reflecting the light emitted by the LED, so as to form a cut-off line at an edge in a side of the projection lens, of the reflection face.
