Abstract

L'invention fournit une lampe d'éclairage à DEL présentant un degré élevé de liberté de conception, et permettant à la fois un rendement de matériaux et une réduction du coût du travail à l'assemblage. Cette lampe d'éclairage à DEL est équipée : d'une DEL (1) constituant une source de luminescence; d'un substrat de DEL (2) sur lequel la DEL (1) est montée; et d'un élément de dissipation de la chaleur (14) sur lequel le substrat de DEL (2) est installé. Le substrat de DEL (2) est installé de manière à ce qu'une face de montage de DEL prenne une position verticale suivant la direction d'irradiation de la lampe. Ainsi, pour la DEL (1) qui est installée sur le substrat de DEL (2), il est possible d'adopter soit un mode vue latérale présentant une luminescence dans une direction suivant la face de montage, soit mode vue d'en haut présentant une luminescence s'orientant vers le haut de la face de montage. En outre, un montage combinant ces deux modes, est également possible. Par conséquent, en comparaison avec les lampes de l'art antérieur, le degré de liberté de conception s'élève de manière remarquable.
