Abstract
A halogen lamp includes a pair of lead members, a filament bonded to and between the pair of lead members and a glass bulb encasing and sealing the filament and at least portions of the pair of lead members. The lamp further includes a support member made of non-conductive material and adapted for fixedly interconnecting legs of the pair of lead members, with the support member being disposed within the glass bulb. The lead members and the filament are bonded together by plasma welding.
Claims7
A halogen lamp comprising:
- a pair of lead members;
- a filament bonded to and between the pair of lead members;
- a glass bulb encasing and sealing the filament and at least portions of the pair of lead members;
- and
- a support member made of non-conductive material and adapted for fixedly interconnecting legs of the pair of lead members, said support member being disposed within said glass bulb;
- wherein said lead members and the filament are bonded together by plasma welding.
A method of manufacturing a halogen lamp including a pair of lead members, a filament bonded to and between the paired lead members and a glass bulb enclosing at least portions of the paired lead members and the filament, the method comprising the steps of:
- fixedly interconnecting legs of a pair of lead members with a support member made of non-conductive material, said lead members being fixed to a jig in advance;
- welding a filament to and between said pair of lead members whose legs were fixedly interconnected to each other in the fixedly interconnecting step;
- and
- disposing a glass bulb so as to enclose at least the filament welded to the paired lead members and the support member and subsequently sealing portions of the paired lead members by sealing a base end of the glass bulb with clamping the paired lead members therein.
A method of manufacturing a halogen lamp including a pair of lead members, a filament bonded to and between the paired lead members and a glass bulb enclosing at least portions of the paired lead members and the filament, the method comprising the steps of:
- welding the filament to and between the pair of lead members fixed to a jig;
- fixedly interconnecting respective legs of the pair of lead members welded to the filament in the welding step with a support member made of non-conductive material;
- and
- disposing a glass bulb so as to enclose at least the filament welded to the paired lead members and the support member and subsequently sealing portions of the paired lead members by sealing a base end of the glass bulb with clamping the paired lead members therein.
