Abstract
A lighting system including a lighting panel, wherein at least one light source, assigned to a narrow side of the lighting panel, is provided for coupling light into the lighting panel. The lighting system also includes a reflector facing a flat side of the lighting panel, wherein the flat side of the lighting panel facing the reflector and/or the reflector and/or an intermediate layer between the reflector and the lighting panel is provided with a surface structure. The surface structure is formed as a line grid made of continuous and intersecting grid lines. According to the lighting system, a high level of homogenization of the light emission from the lighting panel can be achieved in a simple manner. In this way, in particular, greater transmission losses in the edge regions of the lighting panel are prevented.
