Abstract
Una lámpara eléctrica, que tiene una envolvente de la que al menos una parte es generalmente tubular, estando dicha porción herméticamente cerrada de una forma estanca al vacío por un cierre con constricción alrededor de al menos un alambre para suministro de corriente, de molibdeno, que tiene un diámetro D, que se extiende desde la parte exterior de la envolvente de la lámpara hasta un elemento eléctrico situado en la envolvente de la lámpara, consistiendo dicha porción de la envolvente de la lámpara en un vidrio de aluminio borosilicato de metal alcalino que tiene un coeficiente de expansión térmica entre 31 y 37 x 10^-7ºC^-1 a 0-300ºC, caracterizada porque el vidrio del cierre con restricción de la envolvente generalmente tubular de la lámpara está fundido directamente al alambre de suministro de corriente y se extiende hacia el interior de la envolvente de la lámpara circunferencialmente alrededor del alambre de suministro de corriente en una campa que es más delgada que D/2 en una longitud de al menos D/2.
