Abstract

La présente invention se rapporte à une lampe fluorescente du type plat qui induit une décharge ayant une partie droite dans un espace de décharge, ceci permettant d'améliorer l'efficacité de l'émission lumineuse ainsi que l'uniformité de la luminosité tout en économisant l'énergie électrique. Une lampe fluorescente du type plat inclut un corps de lampe définissant un espace de décharge interne, des écarteurs installés dans le corps de lampe de manière à définir l'espace de décharge interne et un chemin de décharge, une couche de luminophores appliquée sur une surface interne du corps de lampe, et des électrodes en opposition installées sur des côtés opposés du corps de lampe, respectivement.
