Claims

1. A lamp for a vehicle, comprising:

a housing accommodating a mirror therein; and

a signal lamp provided on a portion of an outer surface of the housing,

wherein the signal lamp comprises;

a reflecting portion;

a lens unit located in front of the reflecting portion to be spaced apart from the reflecting portion and including a half mirror formed on at least a portion of a surface of the lens unit;

a supporting portion having an opening and located between the reflecting portion and the lens unit; and

a light source unit including a plurality of light sources disposed along a peripheral edge of the opening,

wherein the signal lamp forms an original image of the light source unit and one or more reflected images obtained by reflecting the original image.

2. The lamp of claim 1, wherein the signal lamp is provided on at least a portion of a front side of the mirror housing, on at least a portion of a lateral side of the mirror housing, or on both.

3. The lamp of claim 1, wherein the reflecting portion is located at one side of the lamp housing.

4. The lamp of claim 1, wherein the reflecting portion includes a metal coating layer formed on at least a portion of a surface of the housing facing the lens unit.

5. The lamp of claim 1, wherein the half mirror includes a metal coating layer formed on at least a portion of a surface of the lens unit, or is attached to the lens unit in the form of a film.

6. The lamp of claim 1, wherein the half mirror is formed on at least a portion of an inner surface of the lens unit, on at least a portion of an outer surface of the lens unit, or on both.

7. The lamp of claim 1, wherein a plurality of exposure holes are formed in the supporting portion to expose the plurality of light sources along the peripheral edge of the opening.

8. The lamp of claim 7, wherein the light sources generate light through an inner lens provided on or near the light sources.

9. The lamp of claim 1, wherein the light sources are classified into a plurality of groups, each group including one or more light sources, and the plurality of groups are turned on sequentially in a predetermined direction.
