Abstract

Official abstract text for this publication.

A vehicle lamp forms an additional high-beam light distribution pattern with light emitted though a projection lens from a plurality of light emitting elements. The plurality of light emitting elements are disposed to be aligned in a transverse direction below a rear focal point of the projection lens and can be lit individually. The vehicle lamp forms an additional light distribution pattern by lighting the plurality of light emitting elements at the same time to form a high-beam light distribution pattern. In addition, the vehicle lamp forms another additional light distribution pattern where a part of the additional light distribution pattern is omitted by selectively lighting a part of the plurality of light emitting elements so as to form an intermediate light distribution pattern.

First claim

Opening claim text (preview).

The invention claimed is: 1. A vehicle lamp configured to selectively perform low beam illumination and high beam illumination, wherein the vehicle lamp comprises a projection lens, and a light source which is disposed behind the projection lens and is configured to emit light forwards through the projection lens, wherein a shade and a plurality of light emitting elements are disposed behind the projection lens, the shade being configured to cut off a part of light which is emitted from the light source to be directed towards the projection lens to form a low-beam light distribution pattern, the plurality of light emitting elements being configured to emit light which enters the projection lens to form an additional high-beam light distribution pattern to be added to the low-beam light distribution pattern, and wherein the plurality of light emitting elements are disposed to be aligned in a transverse direction below a rear focal point of the projecting lens and are configured to be lit individually, wherein the plurality of light emitting elements are disposed with their light emitting surfaces facing a front of the vehicle lamp or with their light emitting surfaces directed obliquely upwards with respect to a direction to the front of the vehicle lamp. 2. The vehicle lamp according to claim 1 , wherein the shade is formed to extend obliquely upwards and rearwards from a vicinity of a rear focal plane of the projection lens, and wherein the plurality of light emitting elements are disposed behind a front end edge of the shade. 3. The vehicle lamp according to claim 1 , wherein the projection lens is formed such that a rear focal point of an upper area of the projection lens is positioned below a rear focal point of a general area of the projection lens which is an area other than the upper area. 4. The vehicle lamp according to claim 1 , wherein when the plurality of light emitting elements are disposed with their light emitting surfaces facing the front of the vehicle lamp, the light emitting surfaces directly face the front of the vehicle lamp. 5. The vehicle lamp according to claim 1 , wherein the plurality of light emitting elements are supported by a front surface portion of a base member which has at least a part thereof directly facing the front of the vehicle lamp. 6. The vehicle lamp according to claim 1 , wherein the projection lens is supported by a lens holder at an outer circumferential flange portion thereof, and wherein the plurality of light emitting elements are disposed inwards in a radial direction from the lens holder.
