1. A vehicle lamp comprising:
a substrate;
first and second elongated light sources disposed in parallel on one side of the substrate, and configured to extend along a first direction with respect to the substrate; and
a lens disposed on the one side of the substrate, and configured to extend along the first direction to cover three sides of the first and second elongated light sources,
wherein a cross-section of the lens along an imaginary plane in a second direction and perpendicular to the first and second elongated light sources and the substrate comprises a portion of an ellipse, wherein the second direction is perpendicular to the first direction,
wherein the cross-section of the lens has a shape in which a plurality of portions of an ellipse overlap each other,
wherein the cross-section of the lens comprises:
a first elliptical portion defined in a shape of a portion of the ellipse; and
a second elliptical portion defined in a shape of the portion of the ellipse, wherein the second elliptical portion is configured to overlap the first elliptical portion,
wherein the second elongated light source is disposed at a focal point of the first elliptical portion and the first elongated light source is disposed at a focal point of the second elliptical portion, and
wherein two angles defined between a major axis of each of the first and second elliptical portions and the substrate is each half of a beam angle of either one of the first or second elongated light sources.
