Definitions

  • the invention relates to an electric lamp with a sleeve-shaped, essentially metal base and a lamp bulb, which has a pinch and in which an electric light source is arranged, from which current conductors electrically connected to the base emerge through the pinch, the pinch in a metal socket fastened in the base is received by clamping.
  • the light source When using lamps in an optical system, it is important that the light source is in a predetermined position. This position is obtained by placing the light source in a predetermined position with respect to the base.
  • the light center length is set, but there is a lateral displacement of the light source in not possible with respect to the base.
  • the lamp cannot be aligned three-dimensionally and therefore cannot be used for all applications.
  • a lamp is known in which a socket with cement is attached to the lamp bulb.
  • a socket is attached to the socket, which has an inwardly bent edge at its open end, which tightly surrounds the socket.
  • Two diametrically opposite tongues, which are welded to the socket, are pressed inward from the jacket of the base. The length of the light center can be adjusted for this lamp, but a three-dimensional alignment is not possible.
  • a putty-free fastening of a lamp bulb provided with a pinch in a base with the aid of a sleeve-shaped inner part, which receives the pinch by clamping, is already known from DE-OS 29 38 189.
  • the inner part which is provided with inwardly bent pairs of lugs for receiving the bulb pinch, lies closely against the base, so that a longitudinal and rotational movement of the lamp bulb with the inner part relative to the base is also possible here, but a pivoting movement is excluded.
  • an electric incandescent lamp is known from GB-PS 450 948, the lamp bulb of which is fastened with putty in a spherically curved ring which could be aligned in three dimensions with respect to the base.
  • the attachment between base and inner part is done by soldering, for which purpose three holes are provided in the base for receiving the solder. These holes with the connection solder limit the straightening process, particularly in the longitudinal direction.
  • the invention has for its object to provide an electric lamp with a sleeve-shaped base, in which a putty-free unit consisting of lamp bulb and socket is inserted in three dimensions and can then be fixed.
  • the base has at least three indentations distributed over its circumference, which are each attached to the socket, and that the inner diameter of the base - apart from the indentations - over its whole , length opposite the bushing is larger than the outer diameter of the bushing.
  • the bushing Since the bushing is smaller in diameter than the base, it can not only be rotated and moved in the longitudinal direction relative to the base, but also pivoted, with indentations serving as pivot points for the pivoting process.
  • the impressions can be e.g. egg-shaped, conical or spherical impressions or as tongues punched out of the base and pressed inwards.
  • the indentations - based on the mean diameter of the socket - have an oversize of at least 0.1 mm, there is a kind of interference fit when inserting the socket into the base.
  • the axial thrust forces to be applied for the press fit can also be kept small, even with larger manufacturing tolerances, if the socket widens conically in the direction of the lamp bulb in accordance with an advantageous development according to the invention.
  • the bushing is provided with mutually opposite, inwardly bent pairs of tabs which hold the piston pinch.
  • a web remaining between each pair of tabs has an inwardly directed resilient part, e.g. a tongue or an indentation which engages in a corresponding recess in the piston pinch.
  • the pairs of tabs can also be provided with slots into which profiles fitted on the piston pinch engage.
  • the socket is provided with two opposing longitudinal grooves, between which the piston pinch is clamped.
  • Such a mounting of the piston pinch is known per se from DD-PS 140 817.
  • Such longitudinal grooves can be produced relatively easily using a deep-drawing process.
  • the piston pinch protrudes through the bottom of the bushing and a pair of tabs present on the bottom of the bushing holds the pinch in place.
  • the tabs engage behind cams on the pinch in order to obtain an even better locking in the longitudinal direction.
  • Embodiments of lamps according to the invention are advantageous in which the socket abuts the lamp bulb with its open end. The lamp bulb is then in a stable position.
  • one of the current conductors is fastened to the socket, for example welded or soldered, to a tube which may be conical or which is present on the socket or to a tongue, for example U-shaped, which is present on the socket.
  • the base and the socket can be attached to one another by soldering or welding, in particular by resistance welding.
  • 1 and 3 is 1, for example made of hard glass or quartz glass, a bulb of a halogen incandescent lamp, which at its end has a squish 2 which is essentially rectangular in cross section, into which current conductors 3 and 4 made of molybdenum to form a filament 5 as electrical Light source are embedded, the ends 6 and 7 of which protrude from the pinch 2.
  • the pinch 2 is provided with indentations 8 on its two narrow sides.
  • the lamp bulb 1 is held with its pinch 2 in a socket 9 made of sheet metal, which abuts the lamp bulb 1 with its open end.
  • the bushing 9 is provided with punched out, in the axial direction of the lamp and opposite, inwardly bent pairs of tabs 10 and 11, between which the piston pinch 2 is inserted with its recesses 8 clamping.
  • the socket 9, which widens somewhat conically towards the piston, is provided at its bottom with an opening 12 for the ends 6 and 7 of the power supply wires 3 and 4.
  • a U-shaped contact 13 is formed on the bottom of the socket 9 in FIG. 1, to which the wire end 7 is first electrically connected by clamping and then by spot welding.
  • the socket 9 is provided instead of a U-shaped contact with a tightened cone 14, to which the wire end 6 is connected by soldering or welding.
  • the ver between the tab pairs 10 and 11 - remaining webs 15 and 16 respectively as the resilient member a resilient inwardly bent tongue 17 which lockingly engage a corresponding recess 18 of the piston contusion. 2 While the lamp bulb 1 in the socket 9 is secured against rotation by the pairs of tabs 10 and 11, the spring parts 17 engaging in the base recesses 18 achieve a further locking in the longitudinal direction.
  • the socket 40 corresponds to that of the aforementioned European application.
  • the socket 40 has a pair of tongues 41, which holds the pinch 2 of the incandescent lamp in a clamping manner and engages behind the cams 43.
  • a tongue 42 is provided on the socket 40, with which the current conductor 6 is welded.
  • the unit can be mounted in the base of FIGS. 6 and 8.
  • the socket 40 abuts the lamp bulb 1 with its open end.
  • the lamp units shown in FIGS. 1 and 3 can be arranged in a sleeve-shaped base made of thin sheet metal according to FIGS. 6 or 8.
  • the base 19 according to FIGS. 6 and 7 is sleeve-shaped and provided with a base collar 20, on which references 21 are attached for correct insertion into an associated socket.
  • the base 19 has a central base contact 22.
  • the base 19 is provided with four spherical impressions 23 distributed over its circumference, which are in point contact with the socket 9 when a lamp unit according to FIG. 1 is inserted (FIG. 10).
  • the inside diameter of the base 19 - apart from the embossments 23 - is larger than the outside diameter of the socket 9 over its entire length lying opposite the inner part 9. In this way, the lamp unit according to FIG.
  • the socket 9 is connected to the base 19 in the region of the impressions 23 thereof by welding.
  • an extension wire 24 made of manganese-nickel is welded to the free end 6 of the power supply wire 3 and is soldered into the base contact 22.
  • the sleeve-shaped base 29 according to FIGS. 8 and 9 essentially corresponds to the base 19 according to FIGS. 6 and 7. Corresponding parts have therefore been provided with the same reference numerals. Instead of impressions, the base 29 has four resilient tongues 25 punched out and pressed inwards as impressions which, after insertion of a lamp unit according to FIG. 1 or 3 and alignment, can also be connected to the socket 9 by spot welding.
  • connection between the socket 9 and the bases 19 and 29 can also be made by soft soldering.
  • the pockets 26, which are created by punching out the pairs of tabs 10 and 11 in the socket 9, are used as a space for receiving solder paste.
  • the solder paste is applied before inserting the socket into the base. During insertion, the solder paste is partially distributed as a film between the socket and the base. Then only the base needs to be heated from the outside to make a solder connection between it and the socket.
  • the bushing 27 shown in FIGS. 11 and 12 and provided with a U-shaped contact 13 each has two opposing longitudinal grooves 28, between which a piston pinch 2 can be clamped. These longitudinal grooves 28 are also suitable as pockets for holding solder material. - The bushings described so far were manufactured by deep drawing.
  • FIGS. 13 to 16 Another embodiment of a bushing 30 designed as a stamped part is shown in FIGS. 13 to 16.
  • the socket 30 consists of a base part 31 with two roughly semicircular curved jacket halves 32, the edges of which to form pairs of tabs 10 and 11 are turned inwards are arc and serve to accommodate the piston pinch 2.
  • the pairs of tabs 10 and 11 are provided with transverse slots 33, in which cross profiles 34 attached to the piston pinch 2 engage in a locking manner.
  • the spaces 35 between the M Antel halves 32 and the pinch 2 can in turn serve to accommodate solder.
  • the socket 30 is provided on its bottom part 31 with a U-shaped contact 13 for receiving the end of a power supply wire.
