Abstract

A lighting device for a vehicle may include: a housing mounted on a vehicle body; one or more light sources mounted in the housing, and configured to emit light; and a screen having 3D surfaces corresponding to the number of the light sources, and configured to generate a 3D lighting by transmitting the light emitted from the light sources.

First claim

What is claimed is:

1. A three-dimensional (3D) lighting device for a vehicle, comprising:
a housing coupled to a vehicle body;
a plurality of light sources housed in the housing and configured to emit light, the plurality of light sources including first and second light sources configured to emit first and second lights, respectively; and
a screen having a 3D surface configured to transmit the light emitted from the plurality of light sources to generate a 3D lighting, wherein the 3D surface comprises:
a first transmission part configured to generate a first lighting based on the first light emitted from the first light source; and
a second transmission part connected to the first transmission part and configured to generate a second lighting based on the second light emitted from the second light source, the 3D lighting comprising the first and second lightings.

2. The 3D lighting device of claim 1 , wherein the housing is positioned on a front surface of a vehicle body.

3. The 3D lighting device of claim 1 , wherein:
the housing is embedded in the vehicle body and has an open front area, and
the screen is exposed externally from the housing while covering the open front area of the housing.

4. The 3D lighting device of claim 1 , wherein the light source comprises:
a light source case positioned in the housing;
a light source lamp positioned in the light source case and configured to emit the light onto the 3D surface;
one or more light source lenses positioned on the light source case and configured to transmit the light emitted from the light source lamp; and
a light source sheet positioned on the light source case and configured to adjust a light pattern of the light emitted from the light source lamp.

5. The 3D lighting device of claim 4 , wherein the light source sheet is replaceable.

6. The 3D lighting device of claim 4 , wherein the light source sheet comprises:
a sheet base part inserted into the light source case; and
a sheet transmission part formed in the sheet base part and configured to form the light pattern.

7. The 3D lighting device of claim 6 , wherein:
the one or more light source lenses comprises two light source lenses, and
the sheet base part is positioned between the two light source lenses.

8. The 3D lighting device of claim 1 , wherein the first and second transmission parts are integrally formed.

9. The 3D lighting device of claim 8 , wherein the first and second lightings are connected to each other.
