Abstract:
1. An illumination device comprising: a planar light guiding element having a first face and a second face, which are substantially parallel to each other; and an even number of light sources for emitting light from a light emitting side along a main light emission axis, wherein: the planar light guiding element has apertures into which each of the light sources is inserted separately so that the main light emission axis is substantially parallel to and between the first face and the second face, substantially parallel to a first direction, and substantially parallel to a longitudinal axis of the planar light guiding element, the even number of light sources being divided into: the light sources of the first group and the light sources of the second group are each located inside an outer contour of the planar light guiding element at a position located a predetermined distance from a center of the planar light guiding element in a longitudinal direction of the planar light guiding element.
