The present invention relates to a vehicle lamp and, more particularly, to a vehicle lamp using a semiconductor light-emitting device. The present invention provides a vehicle lamp comprising: a substrate; first and second bar-shaped light sources arranged parallel to one side of the substrate and extending along one direction thereof; and a lens disposed on one surface of the substrate and extending along the one direction so as to overlap with the first and second light sources, wherein the cross-section of the lens, which is perpendicular to the extending directions of the two light sources and cut along a virtual plane perpendicular to the substrate, includes a part of an ellipse.

The present invention relates to a light guiding assembly, a vehicle lamp and a vehicle. Specifically, the light guide assembly includes at least a first light guide element and a second light guide element, which can be joined to form a predetermined shape, in the region where the first light guide element and the second light guide element are joined, the parts of the first light guide element and the second light guide element that face each other at least partially overlap, so that light leaving one of the first light guide element and the second light guide element can at least partially enter the other. The vehicle lamp and the vehicle have the abovementioned light guide assembly.

An illuminating device for vehicles, including an elongated light guide, which has an end face for coupling light into the light guide and has a lateral surface, at which the coupled-in light may be totally reflected in a coupling direction. An elongated reflector is arranged so that it follows the light guide and at least partially behind the light guide in the main emission direction. The light guide is designed such that the coupled-in light is coupled out on a rear-side lateral surface and/or side lateral surface facing the reflector and on a front lateral surface facing away from the reflector. The light guide and the reflector each have a corner region, in which sections of the light guide and sections of the reflector enclose an acute or right or obtuse angle.
