## Abstract

A lighting device for a vehicle may include: a lamp part configured to irradiate light; an inducing lens part configured to guide the light irradiated from the lamp part, and having a cut surface formed thereon; an adjusting lens part formed at the front of the inducing lens part, and configured to adjust the direction of the light moved through the inducing lens part; and a light scattering part formed on the cut surface so as to prevent glare caused by light incident on the cut surface.

## Claims

### Claim 1

A lighting device for a vehicle, comprising:
a lamp configured to irradiate light;
an inducing lens configured to guide the light irradiated from the lamp, and the inducing lens comprises a cut surface formed thereon;
an adjusting lens formed at the front of the inducing lens, and configured to adjust a direction of the light moved through the inducing lens; and
a light scatterer formed on the cut surface to prevent glare caused by light incident on the cut surface,
wherein the lamp is located on a plane that is substantially parallel to the adjusting lens, and an angle formed by the cut surface and the plane form a substantially obtuse angle as measured at the lamp.

### Claim 2 (depends on 1)

The lighting device of claim 1, wherein the inducing lens comprises a multi-stage total internal reflection lens, and the cut surface is formed to correspond to a size of the adjusting lens.

### Claim 3 (depends on 2)

The lighting device of claim 2, wherein the cut surface comprises an outer cut surface and an inner cut surface.

### Claim 4 (depends on 3)

The lighting device of claim 3, wherein the outer cut surface is formed to connect the inducing lens and the adjusting lens to each other on a plane, the inducing lens comprises an upper end portion, a lower end portion, a left end portion, and a right end portion, the upper end portion, the lower end portion, the left end portion, and the right end portion are cut so a size of the inducing lens on the plane corresponds to a size of the adjusting lens on the plane.

### Claim 5 (depends on 3)

The lighting device of claim 3, wherein an inner end portion of the inducing lens is cut to form the inner cut surface, so a size of the inner end portion corresponds to a size of the lamp.

### Claim 6 (depends on 2)

The lighting device of claim 2, wherein the cut surface comprises a layered cut surface, and the layered cut surface comprises faults formed on the total internal reflection lens.

### Claim 7 (depends on 1)

The lighting device of claim 1, wherein the adjusting lens forms a low beam pattern by adjusting the direction of light through multiple surfaces.

### Claim 8 (depends on 1)

The lighting device of claim 1, wherein the light scatterer is disposed on the cut surface, and the light scatterer comprises a rough surface.

### Claim 9 (depends on 8)

The lighting device of claim 8, wherein the light scatterer has a surface roughness of 15 to 70 μm.

### Claim 10 (depends on 1)

The lighting device of claim 1, further comprising a light cover surrounding the inducing lens, the light cover configured to restrict movement of light incident on the cut surface.

### Claim 11 (depends on 10)

The lighting device of claim 10, wherein the light cover comprises:
a cover housing comprising the lamp mounted therein; and
a cover prevention part mounted on the cover housing, and covering the inducing lens and the adjusting lens.
