L'unité (10) de source lumineuse comprend deux plates-formes (16) en forme de plaques planes s'étendant suivant l'axe central (O) du culot métallique (40). Les deux plates-formes (16) sont disposées de façon à adopter la forme d'un V. Les LED (11) sont disposées sur la surface avant de chacune des plates-formes (16). Des ailettes (17) de refroidissement sont disposées sur la surface arrière de chacune des plates-formes (16). L'axe central (O) du culot métallique (40) est situé du côté intérieur des deux plates-formes (16) disposées en forme de V. Ainsi, les plates-formes (16) et the ailettes (17) de refroidissement sont disposées de telle manière qu'il n'y ait aucune interférence avec le corps principal (100) d'appareil lorsque le culot métallique (40) est inséré par vissage dans la douille (105).
