摘要： A lamp for a vehicle using micromirrors includes a variable beam forming part that irradiates light and forms variable beam patterns. In particular, the variable beam forming part includes a first optical part that irradiates the light; a reflection part including a plurality of micromirrors and configured to reflect the light of 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. The plurality of micromirrors are configured to adjust their postures between a first posture in which the light incident from the first optical part is reflected in a first direction and a second posture in which the light incident from the first optical part is reflected in a second direction.

摘要： A lamp for a vehicle using micromirrors includes a variable beam forming part that generates light and forms a variable beam pattern. In particular, the variable beam forming part includes a first optical part that irradiates the light; a beam pattern forming part that reflects the light of the first optical part to form the variable beam pattern; and a second optical part that transmits the light reflected from the beam pattern forming part. The beam pattern forming part includes a reflection part including a plurality of micromirrors; and a housing that accommodates the reflection part. The housing includes an anti-reflection member to prevent secondary reflection of the light having been reflected by the reflection part.
