Abstract

L'invention concerne une lampe fluorescente à DEL améliorée, qui est fabriquée selon les mêmes normes que les lampes fluorescentes existantes et peuvent donc remplacer ces dernières en utilisation. Elle concerne plus particulièrement une lampe fluorescente à DEL améliorée, qui peut dissiper la chaleur générée par une source de lumière à DEL lorsque le corps de la lampe fluorescente est un corps de dissipation thermique, et qui utilise un couvercle de diffusion couplé au corps de dissipation thermique en une étape pour diffuser en grand angle la lumière générée par la source de lumière à DEL et fixer de manière stable un module réseau de DEL sur le corps de dissipation thermique. À cette fin, la lampe de l'invention comprend: un corps de dissipation thermique, dont l'intérieur en aluminium est perméable, dont le centre de l'extrémité supérieure comporte une pièce d'assise, qui présente des rainures d'accouplement sur les côtés droit et gauche de l'extrémité supérieure pour coupler un couvercle de diffusion, et présente des rainures taraudées au-dessous des rainures d'accouplement pour fixer des pièces de jonction; une pièce de jonction, auquel un substrat de convertisseur est fixé, et l'autre pièce de jonction, qui sont reliées au corps de dissipation thermique sur les côtés gauche et droit de celui-ci, et un film isolant rectangulaire transparent intégré à celui-ci; un module réseau à DEL placé sur la pièce d'assise du corps de dissipation thermique; et un couvercle de diffusion, en matériau transparent ou non transparent, qui présente des parties saillantes de couplage à ses deux extrémités et comporte en son centre des parties saillantes fixes.
