Abstract
A lamp for vehicle includes a light source unit that generates light, and an optical unit disposed in front of the light source unit. The optical unit includes an incident surface on which the light is incident from the light source unit and an emitting surface through which the light is transmitted to form a predetermined beam pattern. The incident surface of the optical unit includes a plurality of divided regions that are divided in a grid shape, and the plurality of divided regions include at least a first divided region and a second divided region having different distances from a center line that connects centers of the incident surface and the emitting surface of the optical unit. In particular, the first divided region and the second divided region are formed to have different inclination angles with respect to a vertical plane in at least one direction.
