Document Type and Number:
Japanese Patent JP3633627
Kind Code:
B2
Abstract:
The electric mains voltage lamp has a lamp cap with a cylindrical portion abutting a glass envelope. A resilient cover member circumferentially clamps around and covers the cylindrical portion of the lamp cap and has a circumferential, outwardly extending, flexible collar. The cover member may also cover a cylindrical portion of the envelope which is adjacent the lamp cap. If the envelope is tubular in shape, the cover member may be a sleeve closed at an end thereof which is remote from the lamp cap, so as to cover the whole of the envelope. If the lamp has a bulbous envelope, the lamp may have a resilient domeshaped member covering a portion of the envelope opposite the lamp cap and having an overlap with the cover member. The lamp is able to provide a gastight connection to a lampholder.
