Abstract:
A luminous film has a plurality of light-emitting diodes, a carrier layer and a light-conducting layer having microoptical structures which make it possible to deflect multidirectionally emitted light in a common emission direction of the luminous film, in order to allow uniform illumination of the luminous film surface with a low light-emitting diode population of the luminous film.
