摘要： Lighting arrangement (1, 1′) comprising a light source (2) for generating light; a spreading element (3) realized to laterally spread the generated light in a spreading plane (S), defined by an optical axis (AO) of the light source (2) and a longitudinal axis (L) of the spreading element (3), to give an essentially uniform quantity of light per unit area at an emission face (41, 51) orthogonal to the spreading plane (S) and parallel to the longitudinal axis (L) of the spreading element (3) and a light redirecting element (4, 5) arranged to collect the spread light, which comprises a longitudinal planar emission face (41, 51), and is realized to collect the laterally spread light and to emit the collected light essentially uniformly from the emission face (41, 51).
