Abstract

Un substrat de montage (212) sur lequel est montée une DEL (211) s'accouple avec un évidement d'accouplement (31) fourni sur une surface de fixation (221) d'un luminaire (20). Un emplacement au niveau duquel la paroi périphérique interne (311) de l'évidement d'accouplement (31) vient buter contre une surface d'extrémité latérale (215) du substrat de montage (212) présente un creux (313) sur la surface inférieure (312), qui continue depuis la paroi périphérique interne (311) de l'évidement d'accouplement (31), la partie arrondie créée par abrasion par le moule durant le moulage de l'évidement d'accouplement (31) ne venant pas buter contre le substrat de montage (212). Le substrat de montage (212) peut par conséquent être facilement positionné par rapport au luminaire (20) en contact étroit avec celui-ci, ce qui permet de faciliter la procédure d'assemblage et l'effet de rayonnement de chaleur.
