Abstract

La présente invention concerne un dispositif d'éclairage pourvu d'un logement qui est doté d'une première unité réfléchissante faisant face à une surface d'émission de lumière, et de substrats dans lesquels des DEL sont disposées de manière linéaire dans une première direction qui est une direction le long de la première unité réfléchissante, et dans lesquels cette disposition des DEL est formée dans une pluralité d'étages dans une seconde direction croisant la première direction. Dans la disposition des DEL qui est formée dans une pluralité d'étages dans la seconde direction, le nombre de DEL sur l'étage intermédiaire est supérieur au nombre de DEL sur l'un quelconque des autres étages (étage supérieur et étage inférieur).
