Abstract

Official abstract text for this publication.

A vehicle headlight of a small projector type can provide a favorable light distribution for an overhead sign area along with a light distribution used as a low beam. The headlight can include a semiconductor light source and a projector lens including first, second and third light-emitting surfaces. The headlight can project light having high brightness underneath a horizontal cut-off line while projecting other light in the downward direction using the first and third light-emitting surfaces. Additionally, the headlight can be configured to illuminate light having small chromatic aberration toward the overhead sign area using the second light-emitting surface located between the first and third light-emitting surfaces. Thus, the headlight can provide a favorable light distribution pattern used as a low beam and a favorable light distribution pattern for the overhead sign area using the light that color separation is inhibited so as to conform to a vehicular standard.

First claim

Opening claim text (preview).

What is claimed is: 1. A vehicle headlight, comprising: a semiconductor light source having an emitting surface, a center, and an optical axis, the light source configured to emit light having a substantially white color tone, the emitting surface formed in a substantially plane shape, intersecting with the optical axis at a substantially right angle and also intersecting with the optical axis at the center located on the emitting surface of the semiconductor light source; and a…
