Abstract

The present invention relates to a lamp for a vehicle and a vehicle. The lamp includes a housing and a light source arranged in the housing, an opening of the housing being divisible into one or more light emitting regions to correspondingly realize a predetermined light function, wherein the at least one light emitting region is provided with a light distribution element for the light source, the light distribution element having a first light distribution portion and a second light distribution portion, the first light distribution portion being configured to cause light of the light source to leave the light emitting region within a first angular range, and the second light distribution portion being configured to cause light of the light source to leave the light emitting region within a second angular range that is different from the first angular range.

First claim

What is claimed is:

1. A lamp for a vehicle, comprising a housing and a plurality of light sources arranged in the housing, an opening of the housing being divisible into one or more light emitting regions to correspondingly realize a predetermined light function, wherein the at least one light emitting region is provided with a light distribution element for the plurality of light sources, the light distribution element having a first light distribution portion and a second light distribution portion, the first light distribution portion being configured to cause light of the plurality of light sources to leave the light emitting region within a first angular range, and the second light distribution portion being configured to cause light of some of the plurality of light sources to leave the light emitting region within a second angular range that is different from the first angular range, with the first light distribution portion being a first surface of the light distribution element and the second light distribution portion being a second surface of the light distribution element, and the first surface being different than the second surface.

2. The lamp according to claim 1 , wherein the light distribution element is L-shaped, and the first light distribution portion and second light distribution portion respectively form two corresponding legs.

3. The lamp according to claim 1 , wherein the first light distribution portion transitions into the second light distribution portion via a bridge portion, wherein two opposite surfaces of the bridge portion are totally reflecting surfaces.

4. The lamp according to claim 1 , wherein one of the first light distribution portion and second light distribution portion is provided with a first light regulation structure facing the plurality of light sources.

5. The lamp according to claim 4 , wherein the first light regulation structure takes the form of a collimator, wherein the quantity of the collimator is equal to that of the plurality of light sources.

6. The lamp according to claim 4 , wherein a second light regulation structure is provided on at least one surface of the other of the first light distribution portion and second light distribution portion.

7. The lamp according to claim 4 , wherein a third light regulation structure is provided opposite to the first light regulation structure.

8. The lamp according to claim 1 , wherein the light distribution element is formed in one piece.

9. The lamp according to claim 1 , wherein the lamp is a front or tail lamp.

10. The lamp according to claim 1 , wherein the light with the second angular range crosses over the light with the first angular range.

11. A vehicle, comprising a lamp, the lamp with a housing and a plurality of light sources arranged in the housing, an opening of the housing being divisible into one or more light emitting regions to correspondingly realize a predetermined light function, wherein the at least one light emitting region is provided with a light distribution element for the plurality of light sources, the light distribution element having a first light distribution portion and a second light distribution portion, the first light distribution portion being configured to cause light of the plurality of light sources to leave the light emitting region within a first angular range, and the second light distribution portion being configured to cause light of some of the plurality of light sources to leave the light emitting region within a second angular range that is different from the first angular range, with the first light distribution portion being a first surface of the light distribution element and the second light distribution portion being a second surface of the light distribution element, and the first surface being different than the second surface.
