Embodiment 1

[0049] Such as Figure 1-Figure 14 As shown, the far and near light system based on the light guide provided in this embodiment includes a collimator and a light guide 3;

[0050] Specifically, such as Figure 1-Figure 3 As shown, the collimator and the light guide 3 are sequentially arranged along the direction of the light beam 4 emitted by the light source 1, and the light exit surface of the light guide 3 is a convex surface, so that at least one light beam 4 emitted by the light source 1 is sequentially arranged. Through the collimator and the light guide 3, the upper and lower light beams 4 are parallel, and the left and right light beams 4 are diffused to form a light spot 7. Through the combination of different light sources 1, the low beam widening light type, the low beam inflection point light type or the high beam are realized. One of the light types.

[0051] On the basis of the above examples, if Figure 2-Figure 3 As shown, the light exit portion 6 of the col...

Embodiment 2

[0065] Embodiment 2 of the present invention provides a vehicle lamp, including the light guide-based far and near beam system and a light source described in any technical solution of Embodiment 1 above, and the light source is configured to correspond to the collimating light-transmitter;

[0066] The light source is an LED light source or a laser light source.

[0067] The vehicle light provided by Embodiment 2 of the present invention is provided with the light guide-based high and low beam system provided by Embodiment 1, so it has all the beneficial effects of the light guide-based high and low beam system provided by Embodiment 1, and details will not be repeated here.

[0068] Specifically, in the lighting optical system of automobile lights, the forms of far and near light mainly include lens type and reflective type, and the form is single. However, in the far and near light system based on light guide provided by the present invention, the collimating light transmitt...

Abstract

The invention relates to the technical field of automobile lamp illumination systems, in particular to a light-guide-based low-high beam system and an automobile lamp. The low-high beam system comprises a collimating light-transmitting device and a light guide; the collimating light-transmitting device and the light guide are arranged in sequence in the direction of light beams emitted by a lightsource, the light emitting surface of the light guide is a convex surface, so that the light beams emitted by at least one light source are emitted out through the collimating light-transmitting device and the light guide sequentially, and light spots with upper beams and lower beams which are parallel and left beams and right beams which are diffused are formed. According to the scheme, one of alow beam broadening light type, a low beam inflection point light type or a high beam light type is achieved through the combination of the different light sources, and a plurality of functions such as the AFS and the ADB can be realized.

Description

technical field [0001] The invention relates to the technical field of vehicle lamp lighting systems, in particular to a far and low beam system based on a light guide and a vehicle lamp. Background technique [0002] At present, in the lighting optical system of automobile lights, there are mainly two forms of far and near light: lens type and reflective type, and the form is single. Contents of the invention [0003] An object of the present invention is to provide a far and near light system based on a light guide. The low beam, high beam, AFS, ADB and other functions can be realized to solve the single-form technical problem existing in the prior art. [0004] Another object of the present invention is to provide a vehicle lamp having the above light guide-based high and low beam system. [0005] In order to achieve the above object, the present invention provides the following technical solutions; [0006] The far and near light system based on the light guide prov...
