A long life, halogen cycle, incandescent lamp (30) for operation in excess of 85 volts. The lamp comprises a transparent glass envelope (34) having sealed therewithin a tungsten filament (45); a pair of electrical lead-ins (42, 44) connecting the filament and extending exteriorly of the envelope for connection to a supply voltage greater than 100 V; and a fill gas within the envelope, including a halogen, at a pressure of at least three atmospheres. The envelope is constructed of a five component alkaline earth aluminosilicate glass having a composition consisting essentially of, in weight percent from > 58 to about 64 % SiO2, from about 14 to about 17 % Al2O3; from 0 to about 1% B2O3, from 1 to about 6 % MgO, from about 6 to about 12 % CaO, from about 7 to about 17 % BaO and from 0 to about 1.5 % ZrO2.

L'invention concerne une lampe (30) à incandescence à cycle halogène longue durée, destinée à fonctionner à des tensions supérieures à 85 volts. Ladite lampe comprend une enveloppe (34) de verre transparente sur laquelle est scellé un filament de tungstène (45); une paire de fils d'alimentation électriques (42, 44) connectant le filament et sortant de l'enveloppe pour être connectés à une tension d'alimentation supérieure à 100V; et un gaz de remplissage à l'intérieur de l'enveloppe, comprenant un halogène, sous une pression d'au moins trois atmosphères. L'enveloppe est réalisée en un verre obtenu à partir de cinq composants d'aluminosilicate alcalino-terreux dont la composition renferme essentiellement, en pourcentage en masse, de >58 à 64 % environ de SiO2, de 14 environ à 17 % environ de Al2O3; de 0 à 1 % environ de B2O3, de 1 à 6 % environ de MgO, de 6 environ à 12 % environ de CaO, de 7 environ à 17 % environ de BaO et de 0 à 1,5 % environ de ZrO2.
