Abstract
PURPOSE: To simplify and facilitate the production process of a beadless small lamp by deforming either the lead wire or the end of glass bulb in such a direction that the gap between both the components is reduced.
CONSTITUTION: Compression is made beforehand at either of open ends of a glass bulb serving as a package to reduce the gap between the inner circumference of the both ends and the outer circumference of a lead wire 1. Then, a filament 3 and a lead wire 1 are inserted into a bulb 2 and then, both ends of the bulb 2 are sealed vacuum. In stead of compression in the bulb 2, the lead wire 1 is worked near the ends thereof to form a circular flange to reduce the gap between the two components.
