Definitions
- the invention relates to a halogen incandescent lamp without a cement, according to the preamble of claim 1.
- a lamp of this type is disclosed, for example, in US Pat. No. 4,492,893.
- the lamp described here is a halogen bulb with a cementless base for use in a motor vehicle headlight.
- This lamp has a lamp bulb with a pinch seal having two broad sides and two narrow sides, which is fixed by clamping in a recess in a holder part belonging to the base.
- the squeeze foot is fastened in the holder part by means of several fastening or support straps, which act both on the broad sides and on the narrow sides of the squeeze seal. Since the thickness of the pinch seal is uniform over its entire length, the support tabs which are clamped on the broad sides of the pinch seal exert strong pressure on the pinch seal, which can lead to glass injuries on the pinch seal when the lamp is socketed.
- the support tabs acting on the narrow sides of the pinch seal can even cause the pinch seal to split due to their relatively small contact surface and the strong pressure on the narrow sides.
- the halogen incandescent lamp according to the invention is carried by a metallic holder part which is part of the lamp base.
- the holder part has a punched-out section in which the pinch seal of the lamp bulb, which has two broad sides and two narrow sides, is fixed in a clamped manner with the aid of support tabs.
- the support straps are molded onto the holder part and all act on the broad sides of the squeeze seal, which is essentially rectangular in cross section, while the narrow sides of the press seal are arranged in a contactless manner in the recess of the holder part. As a result, the tolerances of the press seal width do not affect the size of the support forces.
- the pinch seal of the lamp bulb is tapered in the base direction, that is to say that the pinch seal has a smaller thickness at its base-side free end than at its end facing away from the base.
- the holder part advantageously has four further support straps, so that both broad sides of the pinch seal have four support or support points in common with the support straps.
- the lamp bulb is also provided with several molded-in depth stops in the transition area to the pinch seal, which are seated on the holder part after the lamp has been installed. These depth stops advantageously lie on four support lugs and exert slight pressure on them. In conjunction with the aforementioned snap lock, they enable the pinch seal to be fixed in the axial position without play in the holder part.
- the holder part according to the invention advantageously consists of stainless steel and not of nickel silver. Then the nickel-plating of the holder part, which pollutes the environment, can be dispensed with.
- Figure 1 is a schematic side view of a cementless halogen bulb according to the preferred embodiment
- Figure 2 is a bottom view of the holder part of the preferred embodiment
- FIG. 3 shows a cross section through the pinch seal of the halogen incandescent lamp according to the preferred exemplary embodiment, the section plane running parallel to the narrow sides of the pinch seal
- FIG. 4 shows a cross section through the holder part according to FIG. 2
- Figure 5 is a partially sectioned side view of the lamp envelope according to the preferred embodiment
- the halogen bulb with a cementless base according to the invention in accordance with the preferred exemplary embodiment to be described in more detail here is a halogen bulb for use in a motor vehicle headlight.
- Figure 1 illustrates the structure of this lamp.
- the halogen incandescent lamp according to the invention has a lamp bulb 1 made of tempered glass which is tightly squeezed on one side.
- the pinch seal 10 of the lamp bulb 1 is fixed in a cup-like holder part 2 made of stainless steel.
- the holder part 2 forms, together with the base sleeve 3 and the adjuster plate 4 formed thereon and with the base stone 5, the lamp base.
- the holder part 2 is welded to the adjustment plate 4 by means of welding lugs 13 punched out of the adjustment plate 4 and bent upwards.
- One of the filaments 6 is provided with an anti-glare hood 12.
- FIGS. 2 to 5 The lamp parts essential for understanding the invention are shown in FIGS. 2 to 5.
- Figure 2 shows the holder part 2 of the halogen incandescent lamp according to the invention viewed from below.
- FIGS. 3 and 4 illustrate the interaction of the press seal 10 and the holder part 2.
- the holder part 2 has a punched-out recess 20 in which the press seal 10 is fixed in a clamping manner.
- Six support brackets 21a, 21b, 22a, 22b, 23a, 23b, which are angled downward, are formed on the holder part 2, that is to say in the direction of the contact lugs 9, and they clamp against the broad sides of the pinch seal 10, which is essentially rectangular in cross section.
- support brackets 22a, 22b, 23a, 23b are stiffened by means of beads which give them an approximately V-shaped cross section in the horizontally running section, while the two remaining support tabs 21a, 21b each have an approximately centrally arranged recess 24a, 24b.
- These recesses 24a, 24b are matched in each case to a guide web 50a, 50b molded onto the broad sides of the pinch seal 10.
- the guide webs 50a, 50b run in the longitudinal direction, that is to say parallel to the narrow sides of the pinch seal 10, and are arranged approximately centrally on the broad sides of the pinch seal 10.
- nose-like elevation 51a, 52a, 51b, 52b on each side of the guide webs 50a, 50b, which are also integrally formed on the pinch seal 10.
- the upper edge of these 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 tapered downwards, that is to say in the direction of the base.
- the thickness of the pinch seal 10 is approximately 3.4 mm below the nose-like elevations 51a, 52a, 51b, 52b and about 3.8 mm above the nose-like elevations 51a, 52a, 51b, 52b.
- the narrow sides of the pinch seal 10 are encircled without contact by circularly curved edges 25 of the cutout 20 in the holder part 2.
- the pinch seal 10 is also equipped with four depth stops 53a, 54a, 53b, 54b, which are formed on the broad sides of the pinch seal 10 in the transition region to the lamp bulb 1. After installation, these depth stops 53a, 54a, 53b, 54b are seated on the support tabs 22a, 22b, 23a, 23b, which protrude from the cover surface of the holder part 2 because of their beads.
