Abstract: A method of attaching an extra fine filament of a halogen lamp. A support is fixed on an inner wall of an envelope. A mount having a filament is inserted into the envelope so that the filament is held by the support. The end of the envelope is heated and sealed so as to embed in the seal part of the mount in a sealing section formed on the end of the envelope.

Abstract: A method of sealing a lamp includes: providing a lamp envelop having an envelop body, and first and second end portions which are open; inserting a mount including a filament and a resilient retainer into the lamp envelop through one of the open end portions until the mount is retained within the lamp envelop by the resilient retainer; heating the first open end portion of the lamp envelop to soften and shrink and then optionally pinching the heated portion thereby sealing the first open end portion with one end of the mount embedded therein; and heating the second open end portion of the lamp envelop to soften and shrink and then optionally pinching the heated portion thereby sealing the second open end portion with an opposite end of the mount embedded therein.

Abstract: A method of sealing a halogen lamp including: providing a lamp envelop having an envelop body, an open end portion and a closed end portion: inserting a mount including a filament into the lamp envelop through the open end portion thereof; heating the closed end portion of the lamp envelop to soften and shrink thereby sealingly embedding one end of the mount in the closed end portion of the lamp envelop, while providing a reduced pressure in the lamp envelop; filling the lamp envelop with a required gas; and heating the open end portion of the lamp envelop to soften and shrink thereby sealingly embedding the other end of the mount in the closed end portion of the lamp envelop.
