Abstract

L'invention porte sur un appareil d'éclairage, lequel appareil comprend un luminaire, une section de dissipation de chaleur, un trou d'introduction de fils électriques et un couvercle de fils électriques. Le luminaire a une première surface et une seconde surface, qui sont positionnées sur les côtés opposés dans la direction de l'épaisseur, et la première surface comporte une région de source de lumière pour disposer une source de lumière. La section de dissipation de chaleur est disposée sur la seconde surface du luminaire. Le trou d'introduction de fils électriques est configuré de façon à pénétrer dans le luminaire à partir de la première surface jusqu'à la seconde surface de façon à faire traverser le fil électrique qui est électriquement connecté à la source de lumière. Le couvercle de fils électriques fait face à la seconde surface de façon à couvrir le trou d'introduction de fils électriques. Le couvercle de fils électriques et le trou d'introduction de fils électriques sont disposés en des positions qui ne chevauchent pas la région de source de lumière dans la direction de l'épaisseur du luminaire.
