Abstract

Selon la présente invention, une partie support (31) d'un abat-jour (30) est soutenue par un corps principal de lampe (22) d'une ampoule à DEL (20) ; en conséquence, il est inutile de proposer des pièces pour la fixation séparée de l'abat-jour (30) et il est possible de réduire les coûts par la réduction du nombre de pièces. Dans cet exemple, le corps principal de lampe (22) possède une surface conique dont le diamètre augmente depuis le côté capuchon de base vers le côté émission de lumière, en conséquence, la partie support (31) peut être aisément soutenue. En outre, une partie conique (32) est formée autour de la partie support (31) ; en conséquence, la partie conique (32) peut être fixée près de l'ampoule à DEL (20) et la répartition de l'intensité lumineuse peut être contrôlée avec une grande précision.
