Abstract

La présente invention concerne un module d'éclairage (1) comprenant: -au moins une bande (7) de sources d'émission de lumière (2), -un guide de lumière (3) comprenant une face de transmission (4) agencée pour transmettre vers un objet à éclairer de la lumière émise par les sources d'émission(2) et une face de renvoi (5) faisant face à la face de transmission (4), Les sources d'émission (2) sont situées à l'intérieur du guide de lumière (3). Selon l'invention, le module comprend en outre pour chaque source de lumière un réflecteur de transmission (12) associé à cette source et ayant une face réfléchissante (13) orientée vers la face de transmission (4) de sorte que le réflecteur de transmission associé à cette source soit situé entre la face de transmission (4) et une surface d'émission(14)de cette source agencée pour la sortie hors de la source de la lumière émise par cette source..
