  • the invention relates to an electric lamp according to the preamble of claim 1.
  • Such lamps are in particular high-pressure discharge lamps or halogen incandescent lamps.
  • GB-A 2,034,016 discloses an electric lamp in which the bulb of the discharge vessel is closed by a conven tional ⁇ pinch.
  • the pinch is homogeneous over its entire width and has a axi ⁇ ale length, which is usually greater than the length of the film.
  • the minimum length of the pinch is greater than the length of the longitudinal ⁇ th film.
  • a disadvantage of this construction is that the overall length of the lamp is often significantly influenced by the length of the pinch.
  • the object of the present invention is to provide an e-lectric lamp, the overall length compared to conventional lamps is significantly reduced, so that the construction of particularly compact light sources is made possible. This object is solved by the characterizing features ⁇ times of claim 1.
  • the pinch in plan view is no longer a substantially rectangular area in which the Einschmelzin of the film and the seal length in the glass are necessarily combined additive. Both sizes are now decoupled from each other, the key to shortening the length is that the seal length in glass can be kept extremely short. It has been known for a long time that it does not require more than 1 to 3 mm squeezing length. Accordingly, the foil is now moved outwardly away from the lamp axis to provide a usable portion across the lamp axis in which the internal structure of the piston can be brought into or close to the usable portion. The usable section is like a bag that extends next to the film. The smallest axial length of the pinch is determined only by the desired sealing length of the glass of the piston. In contrast, the fused-film markedly RESIZE ⁇ SSER may be.
  • a pinch is therefore divided into at least two, often in three sections, transversely to the lamp axis: a first portion in which the film is sealed, and whose axial length is greater than that of the film, and a second portion whose axial length at least the
  • Seal length in the glass corresponds, and which is free of foils.
  • the first section is outside, preferably on both sides, so that it is one or two sections in which the film (s) is sealed. In most cases there is a single second section which is arranged either laterally next to the first section or centrally between two first sections.
  • the usable section may itself already contain a luminous means, in particular an incandescent filament.
  • any known glass can be used as the material of the bulb, that is to say in particular hard glass, vycor, quartz glass or soft glass.
  • Other concepts which for example use a pressed glass plate to achieve a short structural length, can only be realized with soft glass to hard glass, which means a considerable limitation of the permissible temperature load.
  • the shape of the pocket now formed in the pinch which forms the working space, can be chosen arbitrarily and thus adapted exactly to the requirement, the concept is suitable for one-sided as well as two-sided squeezed piston.
  • the shaping can be done by crimping jaws with special shape, which have a suitable recess.
  • the shaping can also be assisted by blowing out, and a pumping stem can also be arranged in the region of the pinch to provide the overpressure necessary when blowing out the mold. But this is not mandatory.
  • the bag should be kept tension-free and not too hot.
  • the new concept makes it possible to reduce the length of a lamp by an order of 10 mm, which corresponds to an order of magnitude of approximately 15% for a typical length of formerly 60 to 70 mm.
  • FIG. 2 shows a discharge lamp squeezed on both sides
  • Fig. 3 is a one-sided pinched incandescent lamp.
  • FIG. 1 shows a discharge lamp 1. It consists of a ceramic discharge vessel 2, which is held along a lamp axis A by a frame 3 in an outer bulb 4 made of quartz glass.
  • the frame 3 comprises a short angularly bent supply line 5 and a long along the inner wall of the outer bulb led supply line 6.
  • the short supply line connects a first power supply 7, which protrudes from the socket near the end of the discharge vessel, with a first film 8 in a pinch 9th
  • the long feed line 6 connects a second Stromzu ⁇ management 10, which from the socket remote end of the discharge vessel protrudes, with a second film 11 of the Quet ⁇ research 9.
  • the two films are in each case transversely with respect to the lamp axis A, and moved to the edge of the pinch seal 9 is connected to outer current supply leads 12th
  • the pinch has in each case a first section 15 which completely encloses the foil in the axial longitudinal direction.
  • a second section 13 remains free between the two films.
  • the pinch free a recess 16, which is funnel-shaped or pocket-shaped, so that the seal length continuously shortened towards the center and reaches in the middle of their minimum seal length DL, in the order of magnitude of 1 to 3 mm.
  • the seal length FL is influenced by the length F of the foils 8, 11 contained therein and is therefore distinct, typically twice or three times as long as DL.
  • the free end 14 of the first power supply 7 is brought close to the recess 16, where ⁇ is significantly reduced by the overall length of the entire lamp. This makes it possible in particular to provide more com ⁇ pact reflector lamps.
  • Figure 2 shows an embodiment in which the outer piston 20 is squeezed on two sides. In each pinch 21 is therefore only a foil 22 made of molybdenum. This is preferably moved to one side transversely to the lamp axis to the outside, so that the recess 23 may be much more pronounced in this case. Therefore, in this variant, the shortening of the overall length is th at Gr Press ⁇ .

The two films 33 are laterally next to the pocket 27 arranged. The inner Stromzu ⁇ guides 34 are laterally transversely led directly to the film 33, which further shortens the length even further.

Abstract

L'invention concerne une lampe dont l'ampoule est fermée par au moins un pincement, ledit pincement présentant au moins deux sections. Une première section contient au moins un film, de sorte que la longueur axiale de cette section corresponde au moins à la longueur du film et la seconde section ne contient pas de film, cette section ayant une longueur axiale minimale inférieure à la longueur axiale de la première section.
