Abstract

La présente invention a trait à une lampe à induction électromagnétique comprenant une structure améliorée de tube de lampe, comportant une structure de base de la lampe à induction électromagnétique. La lampe comporte deux tube en verre droits qui sont reliés à proximité des deux extrémités des deux tubes en verre pour réaliser un forme en (1) dans laquelle les ports des deux tubes en verre droits sont tous deux en saillie. Au niveau d'un port d'un tube en verre droit du tube de lampe est prévu un conduit d'échappement intégré dans lequel est disposée une grille d'amalgame et d'indium. L'invention a également trait à une lampe à induction électromagnétique comprenant une structure de tube de lampe améliorée, comportant une structure de base électromagnétique. Le tube de lampe consiste en un tube double en U, dans lequel est prévu un pont de liaison entre les deux tubes en U. Sur des extrémités supérieures des deux tubes en U se trouvent également un port de démarrage comprenant un conduit d'échappement intégré dans lequel est disposée une grille d'amalgame et d'indium, et plusieurs ports de démarrage secondaires dans lesquels est disposée une grille d'indium seulement. Dans cette invention, le conduit d'échappement de la lampe à induction électromagnétique est disposé dans le tube de lampe, de manière à réduire le risque de rupture. En même temps, le tube de lampe utilise plusieurs grilles d'indium comme démarreur auxiliaire, de sorte que la difficulté de démarrage du tube de lampe dans la lampe à induction de puissance élevée et à boucle longue est résolue.
