Abstract

A lighting apparatus for a vehicle may include a lamp housing part mounted on a vehicle body, a projection optical system disposed within the lamp housing part and configured to radiate light, and a reflection part rotatably disposed in a light path of the light radiated by the projection optical system and configured to reflect, toward a lighting-up surface of the vehicle, the light radiated by the projection optical system.

First claim

What is claimed is:

1. A lighting apparatus for a vehicle, the lighting apparatus comprising:
a lamp housing part mounted on a vehicle body;
a projection optical system disposed within the lamp housing part and configured to radiate light; and
a reflection part rotatably disposed in a light path of light radiated by the projection optical system and configured to reflect, toward a lighting-up surface of the vehicle, the light radiated by the projection optical system,
wherein the projection optical system and the reflection part are provided in a plural number, and
an overlapping area in which light paths of light radiated by the plurality of projection optical systems are intersected is increased or decreased by rotation operations of the plurality of reflection parts.

2. The lighting apparatus of claim 1 , further comprising an outer lens part disposed in front of the light path of the light radiated by the projection optical system and configured to cover the reflection part.

3. The lighting apparatus of claim 1 , wherein:
the projection optical system comprises a first projection optical system disposed on a first side of the vehicle body and a second projection optical system disposed on a second side of the vehicle body,
the reflection part comprises a first reflection part disposed on the first side of the vehicle body and configured to reflect light of the first projection optical system and a second reflection part disposed on the second side of the vehicle body and configured to reflect light of the second projection optical system, and
the lighting-up surface is disposed between the first reflection part and the second reflection part.

4. The lighting apparatus of claim 3 , wherein:
each of the first projection optical system and the second projection optical system is provided in a plural number arranged vertically, and
each of the first reflection part and the second reflection part is provided in a plural number arranged vertically.

5. The lighting apparatus of claim 1 , wherein:
the projection optical system comprises a first projection optical system disposed on a first side of the vehicle body and a second projection optical system disposed on a second side of the vehicle body,
the reflection part comprises a first reflection part disposed on the first side of the vehicle body and configured to reflect light of the first projection optical system and a second reflection part disposed on the second side of the vehicle body and configured to reflect light of the second projection optical system, and
the lighting-up surface is disposed below the first reflection part and the second reflection part.

6. The lighting apparatus of claim 5 , wherein:
each of the first projection optical system and the second projection optical system is provided in a plural number in a horizontal direction, and
each of the first reflection part and the second reflection part is provided in a plural number in the horizontal direction.

7. The lighting apparatus of claim 1 , wherein the lighting apparatus is a head lamp of the vehicle.

8. The lighting apparatus of claim 7 , wherein the lighting-up surface is a front grill or a front bump.

9. The lighting apparatus of claim 1 , wherein the reflection part is separately disposed from the lighting-up surface of the vehicle.

10. The lighting apparatus of claim 1 , wherein, as the reflection part rotates, a location of a lighting-up area on the lighting-up surface of the vehicle is adjusted.
