Lamp for vehicle and method therefor

A method of irradiating light by a vehicle, the method comprising:

• providing a plurality of optical systems configured to forming a beam pattern by irradiating light onto a road surface;
• providing an assembly unit configured to assemble and integrate the plurality of optical systems;
• generating light by a light source of each of the optical systems;
• outputting the light input from the light source part by a condensing lens part provided on a front side of the light source part of each of the optical systems;
• shielding a portion of the light input from the condensing lens part by a shield part;
• and
• outputting the light passing the shield part to the road surface an output lens part of each of the optical systems,
• wherein the beam pattern includes a plurality of unit pattern areas formed by the plurality of optical systems, respectively, and
• wherein orientation angle of light output from each of the plurality of optical systems on to the road surface is different from one another.

A lamp for a vehicle, the lamp comprising:

• a plurality of optical systems configured to form a beam pattern by irradiating light onto a road surface;
• a processor configured to control the plurality of optical systems;
• and
• an assembly unit configured to assemble and integrate the plurality of optical systems,
• wherein each of the plurality of optical systems includes:
• a light source part configured to generate light;
• a condensing lens part provided on a front side of the light source part and configured 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 configured to output the light passing the shield part to the road surface, and
• wherein the processor is further configured to:
• control the plurality of optical systems to form a plurality of pattern areas of the beam pattern,
• control orientation angle of light output from each of the plurality of optical systems on to the road surface to be different from one another.
