Abstract
1334453 Filament support wires PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd 19 April 1971 [4 April 1970] 25928/71 Heading H1F A method of providing a support 17 for the filament 7 of a tubular halogen filament lamp comprises embedding a support wire 19 in the pinch seal or pinch seals 3, 5 of the lamp, the support wire extending substantially along the lamp envelope having a fusible metal part or parts 37, 39, each of which melts during the operation of sealing the support wire and each said fusible part in the pinch seals, so that the support wire may be held firmly in position by its ends 29, 31 before and during the sealing and afterwards is insulated by the breaks caused by the melting of the fusible metal parts which may be in the form of nickel tubes. The support wire may be of molybdenum. The filament lead-in wires may be formed of the same wire as the filament support wire as continuous links 41, 43 which are later severed.
