Abstract
Provided is a lamp for a vehicle capable of ensuring light efficiency to satisfy the performance requirements for light distribution. The lamp includes a light source portion, a first lens portion with a plurality of micro incident lenses onto which light generated by the light source portion is incident, a second lens portion with a plurality of micro exit lenses corresponding to the plurality of micro incident lenses, respectively, and a shielding portion with a plurality of shields that are disposed on rear focal points of the plurality of micro exit lenses to obstruct a portion of incident light. In particular, a focal distance of a micro exit lens among the plurality of micro exit lenses is shorter than a focal distance of a micro incident lens among the plurality of micro incident lenses, which corresponds to the micro exit lens.
