Abstract

L'invention concerne une lampe à décharge de haute intensité à enveloppe protectrice, par exemple une lampe (10) aux halogénures métalliques de haute puissance, dans laquelle la masse de l'enveloppe protectrice (44) entourant le tube (20) à arc est réduite par réduction de l'épaisseur de l'enveloppe (44) et/ou par utilisation d'une enveloppe (44) de verre au lieu de quartz fondu.
