Definitions

  • the invention relates to a cementless halogen lamp according to the preamble of claim 1.
  • Such a lamp is disclosed, for example, in US Pat. No. 4,492,893.
  • the lamp described here is a halogen incandescent lamp without a cement for use in an automotive headlamp.
  • This lamp has one Lamp bulb with a two broad sides and two narrow sides Crimp seal, which is in a recess of a holder part belonging to the base is clamped fixed.
  • the squeeze foot is fastened in the holder part by means of several fastening or support straps, both on the broad sides and on the narrow sides of the press seal act. Because the thickness of the press seal Is uniform over their entire length, the practice clamping on the broad sides of the Crimp seal adjacent support tabs a strong pressure on the crimp seal from the lamp socket causing glass injuries to the pinch seal can lead.
  • the support straps acting on the narrow sides of the press seal can, due to their relatively small contact area and the strong pressure on the narrow sides, even cause the pinch seal to split.
  • the halogen incandescent lamp according to the invention is made of a metallic holder part worn, which is part of the lamp base.
  • the holder part has a cutout, in the press seal with the two broad sides and two narrow sides the lamp bulb is clamped with the help of support tabs.
  • the support straps are molded onto the holder part and all act on the broad sides of the cross section a substantially rectangular pinch seal, while the narrow sides of the Pinch seal are arranged in the recess of the holder part without contact. As a result, the tolerances of the press seal width do not go into the size of the Support forces.
  • the pinch seal of the lamp bulb is in the direction of the base tapered, that is, that the pinch seal on her base-side, free end has a smaller thickness than at its base-facing The End.
  • the holder part advantageously has four more Support tabs so that both broad sides of the pinch seal with the support tabs have four support or support points in common.
  • the lamp bulb is also in the transition area to the pinch seal with several molded depth stops provided after mounting the lamp on the Sit on the holder part. These depth stops are advantageously on four support tabs and put a little pressure on them. Together they enable a play-free axial position fixation of the Crimp seal in the holder part.
  • the holder part according to the invention advantageously consists made of stainless steel and not of nickel silver. Then the environment can be polluted Nickeling of the holder part can be dispensed with.
  • FIG. 1 illustrates the structure of this lamp.
  • the halogen incandescent lamp according to the invention has a lamp bulb 1 made of tempered glass, tightly squeezed on one side.
  • the pinch seal 10 the lamp bulb 1 is clamped in a cup-like holder part 2 made of stainless steel fixed.
  • the holder part 2 forms together with the base sleeve 3 and the molded thereon Adjustment plate 4 and with the base stone 5 the lamp base.
  • the holder part 2 is via welding tabs punched out of the adjusting plate 4 and bent upwards 13 welded to the adjustment plate 4.
  • FIGS 5 The lamp parts essential for understanding the invention are shown in FIGS 5 shown.
  • Figure 2 shows the holder part 2 of the halogen incandescent lamp according to the invention viewed from below.
  • Figures 3 and 4 illustrate the interaction of Crimp seal 10 and holder part 2.
  • the holder part 2 has a punched-out recess 20, in which the pinch seal 10 is fixed by clamping.
  • To the holder part 2 are six angled downwards, that is in the direction of the contact lugs 9
  • Support tabs 21a, 21b, 22a, 22b, 23a, 23b formed, which are clamped on the broad sides of the squeeze seal 10, which is essentially rectangular in cross section.
  • the support brackets 22a, 22b, 23a, 23b are by means of beads which are horizontal to them provide an approximately V-shaped cross section, stiffened, while the two remaining support tabs 21a, 21b each have an approximately central arrangement Have recess 24a, 24b. These recesses 24a, 24b are fit on a respective guide web formed on the broad sides of the pinch seal 10 50a, 50b matched.
  • the guide webs 50a, 50b run in the longitudinal direction, that is, parallel to the narrow sides of the pinch seal 10, and are approximate arranged centrally on the broad sides of the pinch seal 10.
  • On both sides the guide webs 50a, 50b each have a nose-like elevation 51a, 52a, 51b, 52b, which are also molded onto the pinch seal 10.
  • the top edge this nose-like elevations 51a, 52a, 51b, 52b forms together with the free Ends of the support tabs 21a, 21b a snap lock.
  • the pinch seal 10 is downwards, i.e. in the direction of the base, tapers in steps.
  • the thickness of the Pinch seal 10 is below the nose-like elevations 51a, 52a, 51b, 52b approximately 3.4 mm and above the nose-like elevations 51a, 52a, 51b, 52b approx.3.8 mm.
  • the narrow sides of the pinch seal 10 are of circularly curved Edges 25 of the recess 20 in the holder part 2 wrapped around without contact.
  • the pinch seal 10 is also equipped with four depth stops 53a, 54a, 53b, 54b, in the transition area to the lamp bulb 1 on the broad sides of the Crimp seal 10 are formed. These depth stops 53a, 54a, 53b, 54b are seated after mounting on the support tabs 22a, 22b, 23a, 23b, because of their beads protrude from the cover surface of the holder part 2, on.

Abstract

L'invention concerne une lampe à halogène à culot sans mastic, notamment une lampe à halogène destinée à un projecteur automobile. Cette lampe comporte un élément d'appui métallique (2) présentant un évidement dans lequel le joint compressible (10) de l'ampoule (1) est bloqué au moyen de plusieurs colliers d'appui (21a, 21b, 22a, 22b, 23a, 23b). Afin de réduire le risque d'endommagement du joint compressible (10) lors du montage du culot, le joint compressible (10) se rétrécit graduellement en direction du culot et tous les colliers d'appui (21a, 21b, 22a, 22b, 23a, 23b) qui agissent sur le joint compressible (10) sont orientés contre les côtés larges du joint compressible (10), pratiquement rectangulaire en coupe, tandis que les côtés étroits du joint compressible (10) sont disposés sans contact dans l'élément d'appui (2).
