Abstract

Le réflecteur de lumière pour lampe fluorescente selon la présente invention comporte une pluralité de surfaces réfléchissantes qui sont inclinées de manière concave à des angles variables prédéterminés pour réfléchir au maximum les rayons lumineux émis par une lampe fluorescente, et une paire de dispositifs de couplage qui sont assemblés aux deux extrémités du réflecteur pour que lesdits dispositifs de couplage soient positionnés à demeure sur les bouchons de l'ampoule fluorescente. La lumière réfléchissante produite par le réflecteur de lumière de l'invention peut rayonner vers la direction désirée lorsqu'on règle l'angle déterminé du réflecteur de lumière. Le réflecteur de lumière présente bien du fait du positionnement d'une paire de dispositifs de couplage qui sont assemblés sur les deux extrémités du réflecteur de lumière, sur les bouchons de l'ampoule fluorescente.
