Abstract

Una lámpara eléctrica perfeccionada que tiene una ampolla o envuelta de lámpara tubular en la cual un filamento de alambre arrollado helicoidalmente está dispuesto axialmente entre conductores de suministro de corriente, los cuales pasan a través de la pared de la ampolla de la lámpara de una manera hermética, cuyo filamento está soportado entre sus extremos por al menos un apoyo de alambre el cual tiene una parte en espiral que por un extremo está en contacto con la pared de la ampolla de la lámpara y por otro extremo cambia a un aparte arrollada helicoidalmente que está en contacto con el filamento, caracterizada porque el filamento tiene partes de doble enrrollamiento que están conectadas por una parte de simple enrollamiento, el diámetro interior de las espiras de la cual se corresponde con el diámetro interior de las espiras secundarias de las partes de doble enrrollamiento, rodeando la parte arrollada helicoidalmente del apoyo de alambre a la parte de simple enrollamiento del filamento.
