Abstract:
A glass screw base of a bulb is provided with a first channel for accomodating solder filling used for mechanical locking of the glass base to a metal screw shell. A second, narrow channel is made in the base to receive a lead wire and direct it to the rim of the shell whereupon an electrical contact is established by a minimal amount of solder and solder flux.
