## Abstract

Disclosed is a lamp for a vehicle including a first lamp module including a first light source part, and a first lens part that forms a first light distribution pattern with light irradiated from the first light source part, a second lamp module including a second light source part, and a second lens part that forms a second light distribution pattern with light irradiated from the second light source part, and a third lamp module including a third light source part, and a third lens part that forms a third light distribution pattern with light irradiated from the third light source part, the first lens part, the second lens part, and the third lens part are connected to each other to define one body having a light output lens surface including multi-facet lenses formed to be gradually stepped from an inboard side to an outboard side of the vehicle.

## Claims

### Claim 1

A lamp for a vehicle, comprising:
a first lamp module including a first light source part and a first lens part configured to form a first light distribution pattern with light irradiated from the first light source part;
a second lamp module including a second light source part and a second lens part configured to form a second light distribution pattern with light irradiated from the second light source part; and
a third lamp module including a third light source part and a third lens part configured to form a third light distribution pattern with light irradiated from the third light source part, wherein:
the first lens part, the second lens part, and the third lens part are connected to each other to define one body,
an output surface of the first lens part, an output surface of the second lens part, and an output surface of the third lens part are integrated to form one light output lens surface to provide output light from the vehicle lamp, and
the light output lens surface includes a plurality of multi-facet lenses are formed to be gradually stepped toward an opposite direction to an output direction of the output light as the multi-facet lenses extend from one side to an opposite side of the light output lens surface in a leftward/rightward direction.

### Claim 2 (depends on 1)

The lamp of claim 1, wherein the first lamp module, the second lamp module, and the third lamp module are arranged in a specific form providing one or a plurality of first lamp modules, one or a plurality of second lamp modules, and one or a plurality of third lamp modules.

### Claim 3 (depends on 1)

The lamp of claim 1, wherein the plurality of multi-facet lenses are formed such that steps between adjacent multi-facet lenses become larger as they extend from the one side to the opposite side in the leftward/rightward direction.

### Claim 4 (depends on 1)

The lamp of claim 1, wherein, when an imaginary surface obtained by connecting centers of adjacent multi-facet lenses in the leftward/rightward direction is defined as an imaginary inclined surface, an angle of the imaginary inclined surface being formed to become larger in a lamp module disposed from the one side more toward the opposite side of the light output lens surface in the leftward/rightward direction.

### Claim 5 (depends on 1)

The lamp of claim 1, wherein the first lens part includes a first input surface to which the light is input, wherein:
the second lens part includes a second input surface to which the light is input,
the third lens part includes a third input surface to which the light is input, and
the first input surface, the second input surface, and the third input surface are formed to be stepped to face the opposite direction to the output direction as they extend from the one side to the opposite side in the leftward/rightward direction.

### Claim 6 (depends on 5)

The lamp of claim 5, including a plurality of first lamp modules, a plurality of second lamp modules, and a plurality of third lamp modules, wherein:
a plurality of first input surfaces provided in the plurality of first lamp modules are stepped with each other,
a plurality of second input surfaces provided in the plurality of second lamp modules are stepped with each other, and
a plurality of third input surfaces provided in the plurality of third lamp modules are stepped with each other.

### Claim 7 (depends on 1)

The lamp of claim 1, wherein:
a horizontal focus and a vertical focus of the first lens part are formed to be coincident, and
a horizontal focus and a vertical focus of the second lens part are formed to be coincident.

### Claim 8 (depends on 1)

The lamp of claim 1, wherein a location of the third lens part, at which the light is concentrated on a horizontal direction, and a location of the third lens part, at which the light is concentrated on a vertical direction, are noncoincident.

### Claim 9 (depends on 1)

The lamp of claim 1, wherein:
the first lamp module includes a first reflection part configured to concentrate the light irradiated from the first light source part,
the second lamp module includes a second reflection part configured to concentrate the light irradiated from the second light source part,
the third lamp module includes a third reflection part configured to concentrate the light irradiated from the third light source part, and
at least one of sizes and shapes of the first reflection part, the second reflection part, and the third reflection part are formed to be mutually different.

### Claim 10 (depends on 9)

The lamp of claim 9, wherein the first reflection part, the second reflection part, and the third reflection part are disposed to face a direction opposite to the output direction as they extend from the one side to the opposite side in the leftward/rightward direction.

### Claim 11 (depends on 9)

The lamp of claim 9, wherein:
the first lamp module includes a first shield part configured to shield a portion of the light reflected by the first reflection part,
the second lamp module includes a second shield part configured to shield a portion of the light reflected by the second reflection part,
the third lamp module includes a third shield part configured to shield a portion of the light reflected by the third reflection part, and
the first shield part, the second shield part, and the third shield part have at least one of different sizes and shapes with respect to each other.

### Claim 12 (depends on 11)

The lamp of claim 11, wherein the first shield part, the second shield part, and the third shield part are disposed to face an opposite direction to the output direction as they extend from the one side to the opposite side in the leftward/rightward direction.

### Claim 13 (depends on 11)

The lamp of claim 11, wherein the third shield part is disposed on a vertical focus of the third lens part.

### Claim 14 (depends on 1)

The lamp of claim 1, wherein:
