Definitions
- a groove guide parallel to the longitudinal axis of the lamp is conceivable, which is then advantageously arranged in the border area of the crushed glass to the thickened central part of the crushing.
- combined grooves are also possible, which are composed of individual grooves arranged perpendicularly and parallel to the lamp axis and, for example, result in the shape of a T.
- the base pins 24 have already been electrically connected to the power supply lines 3 before being crimped and then melted into the crimp 2 over part of their length.
- the cover cap 25 merely fulfills the function of mechanical protection of the pinch 2.
- grooves 12 or 13 are also provided instead of or in addition to the blind holes 9, these have a greatest width of approximately 2 mm and a depth of approximately 0.4 mm.
- the one-part power leads 3 melted into the pinch 2 have a coefficient of thermal expansion adapted to the glass.
- An oxidized or possibly boraxed iron-nickel-based wire is particularly suitable for the power supply.
