Abstract

Une lampe à décharge dans un gaz comprend un tube de lampe qui comporte des électrodes de décharge aux extrémités du tube de lampe. Un ballast est relié aux électrodes de décharge et à une alimentation électrique. La lampe comprend également des électrodes guides qui sont placées dans la paroi intérieure du tube de la lampe. Les extrémités des électrodes guides sont placées à proximité des électrodes de décharge. Le trajet du courant de décharge entre deux extrémités des électrodes de décharge peut être considérablement raccourci et la nécessité d'une décharge à haute tension instantanée est éliminée en utilisant les électrodes guides au cours du processus d'amorçage de la lampe à décharge. Un amorçage à cathode chaude peut être remplacé par un amorçage à cathode froide et la durée de vie de la lampe peut être efficacement améliorée. De plus, un starter classique de la lampe peut être éliminé et le problème de son remplacement fréquent dû à une détérioration de l'amorçage peut être résolu. L'entretien quotidien de la lampe à décharge s'en trouve facilité.
