The reflector includes a first reflection surface, and a surface of the first reflection surface has an uneven shape in which a plurality of convex regions and a plurality of concave regions are repeated. A recessed section, which is recessed downward, is formed in each of the convex regions of the uneven shape, and a protrusion section, which protrudes upward, is formed in each of the concave regions of the uneven shape. ## Claims ### Claim 1 A lamp for a vehicle, the lamp comprising: a light source configured to emit light; and a reflector configured to receive and reflect the light emitted from the light source, wherein the reflector comprises a first reflection surface, and a surface of the first reflection surface has an uneven shape comprising a plurality of convex regions and a plurality of concave regions, wherein a recessed section is formed in each of the convex regions, and a protrusion section is formed in each of the concave regions. ### Claim 2 (depends on 1) The lamp of claim 1, wherein radii of curvature of some of the plurality of recessed sections are different from radii of curvature of others of the plurality of recessed sections. ### Claim 3 (depends on 1) The lamp of claim 1, wherein radii of curvature of some of the plurality of protrusion sections are different from radii of curvature of others of the plurality of protrusion sections. ### Claim 4 (depends on 2) The lamp of claim 2, wherein the plurality of convex regions are formed such that the curvatures of the recessed sections become smaller as optical paths become longer, and each of the optical paths represents a distance the light emitted from the light source travels until it arrives at the convex region. ### Claim 5 (depends on 2) The lamp of claim 2, wherein the plurality of convex regions are formed such that the curvatures of the recessed sections become larger as optical paths become longer, and each of the optical paths represents a distance the light emitted from the light source travels until it arrives at the convex region. ### Claim 6 (depends on 3) The lamp of claim 3, wherein the plurality of concave regions are formed such that the curvatures of the protrusion sections become larger as optical paths become longer, and each of the optical paths represents a distance the light emitted from the light source travels until it arrives at the concave region. ### Claim 7 (depends on 3) The lamp of claim 3, wherein the plurality of concave regions are formed such that the curvatures of the protrusion sections become smaller as optical paths become longer, and each of the optical paths represents a distance the light emitted from the light source travels until it arrives at the concave region. ### Claim 8 (depends on 1) The lamp of claim 1, wherein the first reflection surface is formed such heights of stepped portions between the convex and concave regions adjacent to each other are constant. ### Claim 9 (depends on 1) The lamp of claim 1, wherein the first reflection surface faces the light source, and the light emitted from the light source directly arrives at the first reflection surface. ### Claim 10 (depends on 1) The lamp of claim 1, wherein the reflector further comprises a second reflection surface that faces the light source, the light emitted from the light source directly arrives at the second reflection surface, and at least a portion of the light reflected from the second reflection surface arrives at the first reflection surface. ### Claim 11 (depends on 10) The lamp of claim 10, wherein the reflector has a bent shape at a region in which the first reflection surface meets the second reflection surface. ### Claim 12 (depends on 10) The lamp of claim 10, wherein a surface of the second reflection surface that faces the light source has a flat shape. ### Claim 13 A vehicle comprising a lamp for a vehicle, wherein the lamp comprises: a light source configured to emit light; and a reflector configured to receive and reflect the light emitted from the light source, wherein the reflector comprises a first reflection surface, and a surface of the first reflection surface has an uneven shape comprising a plurality of convex regions and a plurality of concave regions, wherein a recessed section is formed in each of the convex regions, and a protrusion section is formed in each of the concave regions. ### Claim 14 (depends on 13) The vehicle of claim 13, wherein the lamp is a rear lamp or a signal lamp.
