- the outer bulb 116 has a tubular extension 119 equipped, the tubular extension 118 of the discharge vessel 100 partially encloses.
- the tubular extension 119 of the outer bulb 116 in one formed as a recess receiving device of the base part 111 with the help of an integrated in the base part 111, the tubular Extension 119 of the outer envelope 116 surrounding metal sleeve 120, which is heated with a high-frequency induction signal, so that the between the tubular extension 119 and the metal sleeve 120 arranged plastic 127 melts, melted down.
- the cradle of the base inner part 111 has an annular circumferential the inner base part 111 integrally formed collar 125, both on the inside the tubular extension 119 of the outer bulb and on the Outside of the tubular extension 118 of the discharge vessel 100 rests.
- the collar 125 forms with the base inner part 111 in the region of the receiving device an annular recess that acts as a depth stop for the tubular extension 119 of the outer bulb 116 is used.
- the base sleeve 110 is pot-shaped.
- the inner socket part 111 is complete arranged in the interior 117 of the base sleeve 110.
- the outer wall of the Inner base part 111 is partially of an annular, the inner base part 111 surrounding metal part 121 formed in the base inner part 111 is anchored.
- a metal ring is in the side wall of the pot-like base sleeve 110 122 embedded, which has four integrally formed welding tabs 123. These four welding tabs 123 protrude into the interior 117 of the base sleeve 110 and lie when the base inner part 111 is inserted into the base sleeve 110 and resiliently on the ring-shaped during the subsequent adjustment of the lamp Metal part 121 of the base inner part 111.
- the welding tabs 123 with the annular metal part 121 are adjusted welded and thereby the base inner part 111 and the base sleeve 110 in the adjusted position. So that the welding lugs 123 for which welding tools are accessible, the base sleeve wall 110 in the area of the welding lugs 123 each have an opening 124.
- the figure shows one of the four welding lugs 123 with dashed lines there in the view chosen here, this is usually indicated by the ring-shaped Metal part 121 is covered.
- the annular metal part 121 and the metal sleeve 120 delimit an annular groove 124 in the base inner part 111, in the for the purpose of high-frequency-induced heating of the metal sleeve 120 a conductor loop (not shown) is inserted briefly becomes.
- the welding tabs 123 are angled from the metal ring 122 and protrude into the interior 117 of the base sleeve 110.
- the side wall of the pot-like Base sleeve 110 has one in each case in the area of the welding tabs 123 Breakthrough 124 on.
- the inner base part 111 also has a second, designed as an opening Receiving device for the current feedback 115.
- This Receiving device is a portion of the one encased by ceramic tube 114
- Current feedback 115 arranged so that the insulating material of the inner socket part 111, the electrical insulation of the current feedback 115 improved against the other metal parts arranged in the base.
