Abstract

Conformément à l'invention, les lampes à l'halogène remplies d'un mélange d'un gaz rare et d'hydrobromure, présentent un fixateur d'oxygène qui est un composé intermetallique d'un premier métal et d'un second métal. Le premier métal est tantale, titane, zirconium, hafnium ou niobium, le second métal palladium, platine ou or. Les composés intermétalliques sont tellement stables qu'une réaction s'établit toujours avec de l'oxygène, mais non avec l'hydrobromure. De ce fait, la quantité de fixateur pouvant être introduite dans une lampe n'est pas critique. Application : éclairage sur véhicules notamment.According to the invention, halogen lamps filled with a mixture of a rare gas and a hydrobromide, have an oxygen scavenger which is an intermetallic compound of a first metal and a second metal. The first metal is tantalum, titanium, zirconium, hafnium or niobium, the second metal palladium, platinum or gold. Intermetallic compounds are so stable that a reaction always takes place with oxygen, but not with hydrobromide. Therefore, the amount of fixer that can be introduced into a lamp is not critical. Application: lighting on vehicles in particular.
