1. A lamp for a vehicle comprising a variable beam forming part that irradiates light and forms variable beam patterns, wherein the variable beam forming part comprises:
a first optical part that irradiates the light;
a reflection part including a plurality of micromirrors that reflect the light from the first optical part;
a second optical part that transmits the light reflected by the reflection part; and
a housing that supports the first optical part, the second optical part, and the reflection part,
wherein postures of the plurality of micromirrors are adjusted to a first posture in which the light incident from the first optical part is reflected in a first direction or to a second posture in which the light incident from the first optical part is reflected in a second direction,
wherein the first optical part comprises:
a first optical group that irradiates light for forming a first variable beam pattern; and
a second optical group that irradiates light for forming a second variable beam pattern different from the first variable beam pattern,
wherein the second optical part is disposed on a path of light reflected in the second direction by the plurality of micromirrors and comprises:
a plurality of lenses that transmit the light reflected from the reflection part,
wherein each of the first optical group and the second optical group includes a first lens and a second lens,
wherein the lamp further comprises a support bracket, which comprises:
a first support that supports the first lens of the first optical group and the first lens of the second optical group; and
a second support that supports the second lens of the first optical group and the second lens of the second optical group,
wherein the second support comprises:
a first support portion that supports the second lens of the first optical group; and
a second support portion that supports the second lens of the second optical group, and
wherein a step is formed between the first support portion and the second support portion so that the first support portion protrudes farther than the second support portion, thereby allowing an optical path length between the first lens and the second lens of the first optical group to be longer than an optical path length between the first lens and the second lens of the second optical group.
