The invention relates to a lighting device with a quadrangular lighting surface, wherein the quadrangular lighting surface has a first lateral edge a and an opposing lateral edge ag, wherein the quadrangular lighting surface has a second lateral edge b and an opposing lateral edge bg, wherein the quadrangular lighting surface is constructed modularly of at least a first lighting module and further lighting modules. The at least one first lighting module is triangular, wherein the base surface of the first lighting module has a lateral edge b1 and a vertex E1 opposing this lateral edge b1, and wherein a connecting path between the vertex E1 and an intersection point L1 of a normal line with the lateral edge b1 is a height h1 of the first lighting module, where 0 < h1 <= a and b = b1. |
