Le boîtier (10), le dispositif de source de lumière (20), la lentille optique (30), le réflecteur (40) et l'anneau de surface (50) sont agencés séquentiellement. La bague de surface (50) est fixée sur le boîtier (10) et définit une cavité de réception (70). Le dispositif de source de lumière (20), la lentille optique (30) et le réflecteur (40) sont tous situés dans la cavité de réception (70). Le dispositif d'éclairage à DEL (1) possède une ouverture de sortie de lumière (60). Le dispositif de source de lumière (20) comprend une plaque de source de lumière (201) et une puce de source de lumière à DEL (202) située sur la plaque de source de lumière (201). La lumière provenant de la puce de source de lumière à DEL (202) passe à travers la lentille optique (30), est ensuite réfléchie par le réflecteur (40), et est ensuite émise à partir de l'ouverture de sortie de lumière (60). Le dispositif d'éclairage à DEL (1) n'a pas besoin d'une plaque de diffusion pour rendre uniforme la lumière, augmente l'efficacité lumineuse, et empêche l'éblouissement, ce qui permet d'obtenir un excellent effet d'éclairage.
