Abstract (en)

[origin: EP2166276A1] The arrangement has a set of punctiform individual-light sources (4) i.e. LEDs, arranged one behind the other in a longitudinal direction. A transparent light delivery element (20) is arranged before the light sources, and is viewed in a direction of beam. A light mixing unit comprises a light mixing chamber (6) in form of an elongated hollow space, where the chamber extends itself from the light sources to the delivery element. Side walls (9) of the space are designed in a diffuse reflective manner. A lenticular foil (5) is arranged between the light sources and the chamber.
