Abstract
A metal sleeve 5 grips the press stem 4 of lamp bulb 1. The metal sleeve, ich is set in the metal base structure 10, has a groove 13 at its outer surface. One end 3a of a current lead-in wire 3 is placed in the groove, contacting the metal base shell 10 which thereby can be made a side contact for the lamp. The placement of the wire end 3a in the groove of the metal sleeve 5 avoids interference with adjustment and focussing of the lamp in the base shell.
