## Abstract

A lamp for a vehicle includes: a lens; a first light source positioned at a rear side of the lens and configured to generate a first light; a first reflector configured to reflect the first light toward the lens; a second light source positioned at the rear side of the lens and configured to generate a second light; and a second reflector configured to reflect the second light toward the lens, wherein the first light source is configured to output the first light in a first direction, and the second light source is configured to output the second light in the first direction.

## Claims

### Claim 1

A lamp for a vehicle, comprising:
a lens;
a first light source positioned at a rear side of the lens and configured to generate a first light;
a first reflector configured to reflect the first light toward the lens;
a second light source positioned at the rear side of the lens and configured to generate a second light;
a second reflector configured to reflect the second light toward the lens;
a third reflector configured to reflect the second light reflected by the second reflector, the third reflector comprising a first mirror, a second mirror, and a hinge that is rotatably coupled to the first mirror and the second mirror and that includes a hinge shaft extending in a front and rear direction of the vehicle;
a first driving unit configured to provide first driving force;
a first driving force transfer unit configured to transfer the first driving force to the first mirror;
a second driving unit configured to provide second driving force; and
a second driving force transfer unit configured to transfer the second driving force to the second mirror,
wherein the first light source is configured to output the first light in a first direction, and the second light source is configured to output the second light in the first direction,
wherein the first mirror is configured to, based upon the first driving force, rotate in an up and down direction of the vehicle about the hinge shaft, and
wherein the second mirror is configured to, based upon the second driving force, rotate in the up and down direction of the vehicle about the hinge shaft.

### Claim 2 (depends on 1)

The lamp according to claim 1, wherein the second reflector is positioned between the first reflector and the lens.

### Claim 3 (depends on 2)

The lamp of claim 2, wherein the second reflector is configured and positioned to block a portion of the first light reflected by the first reflector.

### Claim 4 (depends on 3)

The lamp of claim 3, wherein a portion of the first light not blocked by the second reflector passes through the lens to form a first beam pattern.

### Claim 5 (depends on 3)

The lamp of claim 3, wherein the second reflector comprises:
a reflection part having a first surface and a second surface and configured to reflect the second light on the first surface; and
a shield part formed on the second surface of the reflection part opposite to the first surface.

### Claim 6 (depends on 1)

The lamp of claim 1, wherein the first reflector is positioned above the first light source and the first light source is configured to output the first light toward the first reflector in an upward direction, and
wherein the second reflector is positioned above the second light source and the second light source is configured to output the second light toward the second reflector in the upward direction.

### Claim 7 (depends on 1)

The lamp of claim 1, wherein the second light reflected by the third reflector passes through the lens to form a second beam pattern.

### Claim 8 (depends on 7)

The lamp of claim 7, wherein the second beam pattern is biased forward or backward with respect to a reference line, the reference line corresponding to a projection of a horizontal centerline of the lens formed on an entire illumination area of the lamp.

### Claim 9 (depends on 7)

The lamp of claim 7, further comprising a transparent display configured to form an image of a specific content such that during operation, the image of the specific content is formed on a surface.

### Claim 10 (depends on 7)

The lamp of claim 7, further comprising:
a driving unit configured to provide a driving force; and
a driving force transfer unit configured to transfer the driving force to the third reflector,
wherein the third reflector is configured to, based on the driving force, rotate in an up and down direction about a shaft arranged along a left and right direction of the vehicle.

### Claim 11 (depends on 10)

The lamp of claim 10, wherein a projection length of the second light varies depending on the rotation of the third reflector.

### Claim 12 (depends on 1)

The lamp of claim 1, wherein a projection width of the second light varies depending on the rotation of the first mirror and the second mirror.

### Claim 13 (depends on 1)

A vehicle comprising:
a plurality of wheels;
a power source configured to drive at least two of the plurality of wheels; and
the lamp of claim 1.

### Claim 14

A lamp for a vehicle, comprising:
a lens;
a first light source positioned at a rear side of the lens and configured to generate a first light;
a first reflector configured to reflect the first light toward the lens;
a second light source positioned at the rear side of the lens and configured to generate a second light;
a second reflector configured to reflect the second light toward the lens;
a third reflector configured to reflect the second light reflected by the second reflector, the third reflector comprising a first mirror, a second mirror, and a hinge that is rotatably coupled to the first mirror and the second mirror and that includes a hinge shaft extending in a front and rear direction of the vehicle;
a first driving unit configured to provide a first driving force;
a first driving force transfer unit configured to transfer the first driving force to the first mirror;
a second driving unit configured to provide a second driving force; and
a second driving force transfer unit configured to transfer the second driving force to the second mirror,
wherein the second reflector is configured and positioned to block a portion of the first light reflected by the first reflector,
wherein the first mirror is configured to, based upon the first driving force, rotate in an up and down direction of the vehicle about the hinge shaft, and
wherein the second mirror is configured to, based upon the second driving force, rotate in the up and down direction of the vehicle about the hinge shaft.

### Claim 15 (depends on 14)

The lamp of claim 14, wherein the first light source is configured to output the first light in a first direction, and the second light source is configured to output the second light in the first direction.
