Abstract

Der Lampenkolben ist mit einer geschlossenen, Quecksilber enthaltenden Glaskapsel (10) bestückt, die durch induktive Erhitzung geöffnet wird. Die Glaskapsel ist ein länglicher Behälter, in dessen erstes Ende ein Heizdraht (11) eingeschmolzen ist. Der Heizdraht (11) besteht aus zwei haarnadelförmigen Schenkeln (12), die in etwa parallel zueinander angeordnet sind, während die zwei nach außen gebogenen Enden die Verbindung zu einem elektrischen Leiter (6) herstellen. Es werden mehrere Ausführungsformen dargestellt. The lamp bulb is closed with a mercury containing glass capsule (10), which by inductive heating is opened. The glass capsule is an elongated container, in the first end of which Heating wire (11) is melted. The heating wire (11) exists from two hairpin-shaped legs (12), which are approximately are arranged parallel to each other, while the two outward bent ends connecting to one Make the electrical conductor (6). There will be several Embodiments shown.
