Document Type and Number:
Japanese Patent JPH01200503
Kind Code:
A
Abstract:
PURPOSE: To prevent affixation of adhesives to a glass thin tube of a non-linear light-emitting bulb by furnishing a pent roof at the inlet of an injection hole for adhesives.
CONSTITUTION: A pent roof 16 curved inward is furnished at the inlet of an injection hole 14 for adhesives provided in a holder 2, and adhesives 8 to be injected from this hole 14 for fixing a non-linear fluorescent bulb 5 to the holder 2 will not be attached to a glass thin tube 10 for accommodation of amalgam 11. This reduces crack initiation of glass thin tube because of attachment of adhesives and unevenness in the electric characteristics.
