1. A lamp for a vehicle, comprising:
a first lamp module including a first light source part and a first lens part configured to form a first light distribution pattern with light irradiated from the first light source part;
a second lamp module including a second light source part and a second lens part configured to form a second light distribution pattern with light irradiated from the second light source part; and
a third lamp module including a third light source part and a third lens part configured to form a third light distribution pattern with light irradiated from the third light source part, wherein:
the first lens part, the second lens part, and the third lens part are connected to each other to define one body,
an output surface of the first lens part, an output surface of the second lens part, and an output surface of the third lens part are integrated to form one light output lens surface to provide output light from the vehicle lamp, and
the one light output lens surface includes a plurality of multi-facet lenses formed on the one light output lens surface to be sloped to provide a slope on the one light output lens surface between adjacent ones of the multi-facet lenses toward an opposite direction to an output direction of the output light as the multi-facet lenses extend on the one light output surface from one side to an opposite side of the one light output lens surface in a leftward/rightward direction,
wherein:
the plurality of multi-facet lenses of the one light output lens surface are formed such that the slope between the ones of the adjacent multi-facet lenses becomes larger as the multi-facet lenses extend from the one side to the opposite side in the leftward/rightward direction to provide a curvature for the lamp,
a horizontal focus and a vertical focus of the first lens part are formed to be coincident,
a horizontal focus and a vertical focus of the second lens part are formed to be coincident, and
a horizontal curvature and a vertical curvature of an input surface of the third lens part are different from one another so that a location of a horizontal focus, at which the light is concentrated in the horizontal direction, and a location of a vertical focus, at which the light is concentrated in the vertical direction, are different from one another, and so that the vertical focus forms a cut-off line.
