Abstract

La présente invention concerne un tube fluorescent. Le tube fluorescent (100) de la présente invention comprend un corps principal (102), lequel comprend un alésage creux (106) formé dans le sens de la longueur et, une pluralité de prismes (104) formés sur une surface extérieure du corps principal (102) dans le sens de la longueur. Chacun des prismes comprend une partie réfléchissante (112) possédant une section transversale en forme de triangle isocèle rectangle et, une partie réglage d'angle (114) interposée entre le corps principal (102) et la partie réfléchissante (112) et, cette partie réglage possède une section transversale avec un angle vertical dont la taille est déterminée par la position d'une source lumineuse. Cette partie réglage d'angle (114) présente la forme d'un triangle rectangle possédant une base inférieure formée par l'hypoténuse du triangle isocèle rectangle. Ce tube fluorescent est intéressant dans la mesure où il n'est pas nécessaire qu'une source lumineuse soit positionnée au centre de la section transversale du tube, ce qui améliore l'efficacité de fabrication. Par ailleurs, le tube fluorescent de l'invention possède une surface intérieure qui peut non seulement prendre la forme cylindrique mais également une grande variété de formes de sorte que ce tube fluorescent peut être utilisé dans des panneaux publicitaires et dans des afficheurs, réduisant ainsi la consommation électrique. Le tube fluorescent de l'invention est capable de transmettre la lumière à une certaine distance d'une manière efficace.
