Beschreibung
Zusammenfassung:	The invention describes a light emitting assembly (100) comprising: * - a light emitting structure (10) with a first light emission surface (11) comprising one or more point-like light sources, preferably light-emitting diodes, to emit light (L) from the first light emission surface (11); * - a transparent beam shaping structure (20) comprising a second light emission surface (21) and a second light receiving surface (22) opposite to the second light emission surface (21), wherein the second light receiving surface (22) is arranged at a distance (D), preferably of 20 - 30 μm, above the first light emission surface (11) in order to create an air gap (30) between the first light emission surface (11) and the second light receiving surface (22) to receive light (LI) emitted from the light emitting structure (10) within an acceptance angle δ for the beam shaping structure (20) to shape a resulting beam of light (LI) being emitted through the second light emission surface (22); and * - one or more transparent light guiding elements (40) arranged between the beam shaping structure (20) and the light emitting structure (10) being suitably shaped to refract at least a part of light (L2) which is emitted from the first light emission surface (11) under an emergent angle ε larger than the acceptance angle δ towards the beam shaping structure (20). The invention further describes a vehicle light assembly (200) or vehicle front light (300) assembly comprising the light emitting assembly (100). L'invention concerne un ensemble électroluminescent (100) comprenant : * - une structure électroluminescente (10) ayant une première surface d'émission de lumière (11) comprenant une ou plusieurs sources de lumière ponctuelles, de préférence des diodes électroluminescentes, pour émettre de la lumière (L) à partir de la première surface d'émission de lumière (11) ; * - une structure de mise en forme de faisceau transparent (20) comprenant une seconde surface d'émission de lumière (21) et une seconde surface de réception de lumière (22) opposée à la seconde surface d'émission de lumière (21), la seconde surface de réception de lumière (22) étant disposée à une distance (D), de préférence de 20 à 30 μm, au-dessus de la première surface d'émission de lumière (11) afin de créer un entrefer (30) entre la première surface d'émission de lumière (11) et la seconde surface de réception de lumière (22) pour recevoir la lumière (LI) émise par la structure d'émission de lumière (10) dans un
