Abstract
A lighting apparatus may be provided for an interior trim piece of a motor vehicle. The lighting apparatus comprises a light guide strip, comprising at least one light-entry face and a light-exit face, which each extend along a longitudinal direction of the light guide strip, and at least two end sides, lying opposite one another and respectively adjoining the light-entry face or light-exit face. A plurality of point light sources are arranged at the light-entry face. Moreover, the light sources are arranged at an unchanging light source spacing from one another. Here, a boundary spacing between a respective end side and a light source arranged closest to the respective end side corresponds to at most half the light source spacing. Moreover, the light guide strip has, at least in portions, a boundary structuring for at least partial output coupling of light at the end sides.
