LAMP FOR VEHICLE AND METHOD THEREFOR

A lamp for a vehicle and a method therefor are provided. The lamp includes optical systems to form a beam pattern by irradiating light onto a road surface, and an assembly unit to assemble and integrate the optical systems. Each of the optical systems includes: a light source part to generate light; a condensing lens part provided on a front side of the light source part to condense and output the light input from the light source part; a shield part formed to shield a portion of the light input from the condensing lens part; and an output lens part to output the light passing the shield part to the road surface. The beam pattern includes unit pattern areas formed by the optical systems, respectively, and orientation angle of light output from each of the optical systems on to the road surface is different from one another.
