In a wall element for an interior of a vehicle, having a wall area to be illuminated and having an illuminating device which is used to illuminate the wall area, the illuminating device contains a plurality of lighting modules, wherein each of the lighting modules contains a multiplicity of light sources, wherein the lighting module extends straight along a central longitudinal axis and, in the direction of the central longitudinal axis, is placed against identical lighting modules without gaps at the ends, wherein the lighting module in operation has a cone of light which, by using a predefined area that is to be illuminated, extends away from the lighting module and the relative position (R) of which in relation to the lighting module is predefined, is configured in such a way that, on the part of the area that is illuminated by the cone of light, the result is a strip of light extending laterally transversely away from the lighting module, which extends at least over the entire length (L) of the lighting module, along the central longitudinal axis, wherein the wall area is the predefined area to be illuminated.
