It So it is a clip without sidewall. If both clip elements one Sidewall, the height of the side wall of the sub clip is always smaller as the height of the side wall of the main clip. Usually also the diameter the minor clip slightly smaller than the main clip to better the to be able to add both parts. This is the easiest way to accomplish that the two clip elements are joined together.
  • the attached clip mechanism can both solvable and insoluble, e.g. laser welded, be designed. By the joining of the clip elements arises, due to the serving as bearing surfaces Brims, a defined, parallel spacing of the reception plateaus.
  • This distance is chosen so that the spring elements of the clip mechanism on the surface of the end portion, which they surround, rest, usually a squish area of the to be joined lamp bulb. It is intended for the external power supply the lamp envelope closer clip element, namely the secondary clip, a specific Safety distance to the power supply lines are maintained.

  • the holding element 13 is designed in two parts and consists, as shown in detail in the figures 4 and 5, of two joined spring clip elements, namely the main clip 34 and the secondary clip 35 sitting underneath. Both are like a top hat built up. They each have a circumferential brim 36, one at the Inner edge attached side wall 37 and a free end final Lid 38.
  • main clip 34 and slave clip 35 The main difference between main clip 34 and slave clip 35 is the different one Height of the side wall 37. It is in the case of the main clip, in which the Height H of the side wall is typically one to two cm, much larger than in Trap of the secondary clip, in which the height HN of the side wall typically significantly smaller is, and in particular a few mm, about 3 to 6 mm. Under certain circumstances is completely dispensed with the side wall of the side clip. Generally directed the height of the side wall depends on the light center of the in the holding element to be used piston. It may be possible that the Side clip 35A for setting a desired light center no side wall needed, ie a flat disc 71 with corresponding recess 72nd and anti-rotation 73, see Figure 13. At low center of gravity may also require negative values for the height of the sidewall, see Figure 14, i. the side wall 74 extends in the opposite direction, So in the opening 11 of the base stone into it.
  • Both elements have a VerFDschutzmechanismus, in the illustrated embodiment in a recess 39, which is roughly rectangular punched in the brim is, is realized. Both elements have this recess the same way twice.
  • Both elements see also again Figure 4 and 5, also have an approximately rectangular recess 40 in the lid, the pinch 9 of the outer bulb is adjusted.
