Abstract

Selon la présente invention, la durée de vie d'une lampe est prolongée en empêchant une dégradation thermique et une déformation thermique des tiges de support par réduction des effets de convection de chaleur qui surviennent directement au-dessus d'un filament et, de ce fait, par élimination de la déformation du filament. Dans un corps scellé en verre (2) qui est orienté transversalement pendant la fixation de la lampe, un filament en forme de bobine (3) est disposé de manière à s'étendre dans la direction axiale de ce dernier. Des première et seconde tiges de support (L1, L2) qui suspendent et supportent le filament (3) depuis le haut à des positions intermédiaires sur ces dernières avec des fils (W1, W2), le filament (3) se trouvant en position horizontale pendant la fixation de la lampe, sont disposées dans la direction longitudinale du filament (3) et sont également disposées dans des positions décalées vers la gauche et vers la droite, respectivement, par rapport à la position se trouvant directement au-dessus du filament (3), ce qui évite la position se trouvant directement au-dessus de ce dernier pendant la fixation de la lampe.
