Abstract

L'invention concerne un outil permettant d'empêcher la dispersion de fragments, cet outil étant utilisé dans des lampes fluorescentes et comprenant une gaine (111) pour transmettre la lumière, destinée à être insérée sur une lampe fluorescente (1) entre deux embouts (112) qui présentent chacun une partie insertion (113) dans laquelle ladite gaine vient s'insérer. Cette gaine repose donc sur la surface périphérique extérieure de la lampe fluorescente, les extrémités opposées de cette dernière étant insérées dans les embouts. La lampe fluorescente est ainsi protégée par la gaine, ce qui facilite sa manipulation et empêche toute dispersion de fragments de verre, même dans l'éventualité d'une rupture du tube de verre. On obtient donc une lampe fluorescente à sûreté améliorée. L'outil permettant d'empêcher la dispersion de fragments est destiné à être appliqué sur des lampes fluorescentes, et plus particulièrement sur des lampes fluorescentes du type utilisé dans des magasins ou des restaurants.
