Zusammenfassung:	A light emitting device (1) adapted for emitting through a light exit window (22) device light (24) having an adjustable beam profile. Said light emitting device (1) comprises an elongated reflector (2) with a reflector opening (23), the reflector is curved around a central line (CL) and delimits a cavity (3). Said reflector (2) comprises mutually opposite first and second edges (4,5) on either side of the central line (CL) and bordering said reflector opening (23). Rims (10,10a,10b), comprising an inner rim surface (11,11a,11b) facing said cavity (3), are connected to respectively said edges (4,5) at said reflector opening (23), extend along the central line (CL), and border said light exit window (22). Said light emitting device (1) further comprises a peripheral (12) and a central LED light source (13), both arranged on said inner surface (11,11a,11b) and facing away from the light exit window (22). Said peripheral LED light source (12) being arranged to emit first light (14) towards a peripheral reflector portion (9) of the reflector (2), said central LED light source (13) being arranged to emit second light (15) towards a central reflector portion (8) of the reflector (2). Said light emitting device (1) further comprises a divider (16) between said peripheral and said central LED light sources (12,13) such that the second light (15) is screened from directly impinging on the peripheral reflector portion (9). Dispositif électroluminescent (1) conçu pour émettre à travers une lumière de dispositif (24) de fenêtre de sortie (22) possédant un profil de faisceau réglable. Ledit dispositif électroluminescent (1) comprend un réflecteur allongé (2) avec une ouverture de réflecteur (23), le réflecteur est incurvé autour d'une ligne centrale (CL) et délimite une cavité (3). Ledit réflecteur (2) comprend de premier et second bords (4, 5) mutuellement opposés de part et d'autre de la ligne centrale (CL) et bordant ladite ouverture de réflecteur (23). Des rebords (10, 10a, 10b), comprenant une surface de rebord interne (11, 11a, 11b) faisant face à ladite cavité (3), sont reliés respectivement auxdits bords (4, 5) au niveau de ladite ouverture de réflecteur (23), s'étendent le long de la ligne centrale (CL) et bordent ladite fenêtre de sortie de lumière (22). Ledit dispositif électroluminescent (1) comprend en outre un périphérique (12) et une source de lumière à DEL centrale (13), tous deux disposés sur ladite surface interne (11, 11a, 11b) et orientés à l'opposé
