Lighting arrangement

A lighting arrangement comprising a light source for generating light;

• a spreading element configured to laterally spread the generated light in a spreading plane, defined by an optical axis of the light source and a longitudinal axis of the spreading element, to give an essentially uniform quantity of light per unit area at a plane orthogonal to the spreading plane and parallel to the longitudinal axis of the spreading element;
• and
• a light redirecting element provided with a collecting face to collect the laterally spread light and an emission face to emit the collected light,
• wherein the light redirecting element is configured to emit the collected light essentially uniformly from the emission face,
• the emission face is longitudinal planar, and
• the collecting face comprises a plurality of distinct lateral refracting zones for collecting the laterally spread light, wherein a distinct lateral refracting zone comprises a collecting face arranged to collect a light portion having a certain incidence angle range, and a refracting body for refracting the light portion through the emission face.
