Abstract

La présente invention concerne une lampe fluorescente (10) qui se compose d'un tube émetteur de lumière (1) ayant une électrode à chaque extrémité, d'un boîtier (7) ayant une partie de rétention (2) pour retenir les extrémités opposées du tube émetteur de lumière (1) et d'une partie de base (3) pour fournir l'alimentation à l'électrode. La partie de rétention est faite d'un métal et est relativement peu coûteuse. Puisque cette partie présente une résistance à la chaleur suffisante, la lampe fluorescente peut être miniaturisée si on la compare aux tailles de lampes classiques. En outre, la partie de rétention comporte une surface soumise à un traitement d'isolation et par conséquent le risque d'électrocution est réduit. La partie de rétention pourra par exemple être fabriquée en aluminium et comporter une surface soumise à un traitement à l'alumite.
