Abstract

L'ampoule comprend un corps d'ampoule (3), un module à LED (6) comportant plusieurs LED (61) réparties circonférentiellement, et un ensemble de systèmes optiques individuels placé face aux LED, l'ensemble de systèmes optiques comportant plusieurs groupes de systèmes optiques, chaque groupe étant associé à une LED et comportant plusieurs systèmes optiques répartis sur un arc de cercle, et ayant des caractéristiques optiques différentes aptes à procurer des focalisations différentes de la lumière émise par la LED placée face à ces systèmes optiques, et l'ensemble de systèmes optiques étant déplaçable par rotation par rapport au module à LED, de manière à placer sélectivement un des systèmes optiques de chaque groupe devant la LED associée audit groupe, pour modifier l'angle de diffusion de l'ampoule. L'ensemble de systèmes optiques comporte au moins deux ensembles de lentilles (8,9), les lentilles desdits ensembles étant réparties et disposées de manière que chaque système optique soit constitué par un groupe de lentilles (8A, 9A; 8B, 9B; 8C, 9C) axialement alignées comportant une lentille de chacun des dits ensembles (8,9) de lentilles, les caractéristiques des lentilles étant prédéterminées de manière que les groupes de lentilles (8A, 9A; 8B, 9B; 8C, 9C) formant les systèmes optiques associés à une même LED (61) aient des caractéristiques optiques différentes.
