Abstract

Cette invention concerne un tube à arc pour lampe à décharge électrique haute intensité et une lampe à décharge électrique haute intensité pour des automobiles. Le tube à arc présente une forme de globe, d'ellipsoïde ou d'un tube et il est rempli d'une substance pouvant être ionisée. Une première portion de col est une seconde portion de col sont ménagées sur les deux extrémités du tube à arc, respectivement, et diamètres des portions de col se rétrécissant; on observe un angle à 180° entre les deux portions de col. Deux paires d'électrodes sont installées dans le tube à arc. Ces deux paires d'électrodes sont connectées à la sortie du ballast par l'intermédiaire de fils de connexion. Une paire d'électrodes forment un arc qui repose sur l'axe du support de lampe ou qui est vertical par rapport au support de lampe, et l'autre paire d'électrodes s'étend depuis l'axe du support de lampe. La lampe à décharge électrique haute intensité pour automobiles peut être constituée du tube à arc susmentionné conjointement avec une enveloppe et un support de lampe. Le mode de réalisation décrit dans cette invention consistent à placer les deux paires d'électrodes dans le même tube à arc et les positions des arcs (sources lumineuses) peuvent être échangées par échange des deux paires d'électrodes qui peuvent se décharger. Ainsi, la forme des faisceaux de lumière émis et la répartition de la lumière, peuvent être régulées, et la fonction de commutation entre les feux de route et les feux de croisement peut être parfaitement mise en oeuvre. La fonction de ces feux est la même que celle d'une lampe halogène-tungstène double filament classique, 9004, 9007 ou H4, et elle peut être utilisée pour améliorer l'efficacité de l'éclairage pour remplacer les lampes classiques.
