A lighting element, comprising: at least one point light source (1, 11); and a light guide element comprising at least one thin light guide layer (2', 2") having a thickness of about 0,01 mm to about 0,4 mm and light outcoupling structures on at least one portion of the light guide layer (2', 2"), wherein the number, arrangement and size of each outcoupling structure are varied to provide an outcoupling modulation as a function of location resulting in a uniform light outcoupling distribution or brightness of the light incoupled into the light guide element, wherein the light outcoupling structures are surface structures comprising a plurality of discrete groups of fine optic surface relief structures on at least one portion of at least one surface of the thin light guide layer (2', 2"), each discrete group comprises diffractive and/or refractive basic structural features on the order of about 10 μm or less in height, and on the order of about 10 μm or less in one lateral dimension, and height and lateral dimensions of the structural features of the surface relief structures are varied to vary the outcoupling efficiency of the surface relief structures resulting in the uniform light outcoupling distribution or brightness of the light incoupled into the light guide element, characterized in that the light guide layer (2', 2") comprises a region in which the surface relief structures are arranged in small discrete outcoupling structure groups, wherein in said region the maximum distance between said small outcoupling structure groups is 300 μm or less, wherein said region is located adjacent to the at least one point light source (1, 11) and in that, in said region the outcoupling structure groups comprise about 10% or less of the area of the light guide layer (2', 2"). at least one point light source (1, 11); and a light guide element comprising at least one thin light guide layer (2', 2") having a thickness of about 0,01 mm to about 0,4 mm and light outcoupling structures on at least one portion of the light guide layer (2', 2"), wherein the number, arrangement and size of each outcoupling structure are varied to provide an outcoupling modulation as a function of location resulting in a uniform light outcoupling distribution or brightness of the light incoupled into the light guide element, wherein the light outcoupling structures are surface structures comprising a plurality of discrete groups of fine optic surface relief structures on at least one portion of at least one surface of the thin light guide layer (2', 2"), each discrete group comprises diffractive and/or refractive basic structural features on the order of about 10 μm or less in height, and on the order of about 10 μm or less in one lateral dimension, and height and lateral dimensions of the structural features of the surface relief structures are varied to vary the outcoupling efficiency of the surface relief structures resulting in the uniform light outcoupling distribution or brightness of the light incoupled into the light guide element, characterized in that the light guide layer (2', 2") comprises a region in which the surface relief structures are arranged in small discrete outcoupling structure groups, wherein in said region the maximum distance between said small outcoupling structure groups is 300 μm or less, wherein said region is located adjacent to the at least one point light source (1, 11) and in that, in said region the outcoupling structure groups comprise about 10% or less of the area of the light guide layer (2', 2").
