Definitions

  • the invention relates to a halogen lamp according to the Preamble of claim 1.
  • protuberances namely webs formed from the glass wall
  • EP-A 143 917 describes a halogen incandescent lamp pinched on both sides described in which the axial filament by a pair of knobs, which are located at opposite points of the piston wall and the Fix the spiral holder made of wire, only indirectly held at certain points.
  • US-A 3 983 441 and Figure 12 of US-A 5 045 748 discuss a halogen lamp pinched on both sides, with individual filament sections through radially symmetrical constrictions, which the luminous body enclose or surrounded at a distance, are separated from each other.
  • the present invention is in principle for both one-sided and suitable for double-pinched halogen bulbs. She is with the latter However, it is particularly well suited because the luminous elements are relatively long and therefore need one or more punctiform supports. Also be coatings for these lamps, in particular from interference filters, used (IRC or similar), where an exact centering of the axial helix is of particular importance for the operation of the lamp.
  • IRC interference filters
  • the filament of the halogen lamp can be single or double be coiled. It consists of luminous sections and at least one Connection piece on which the selective holder attaches. Prefers the connector can be wound with a greater slope than that glowing sections. In the case of the double helix, there is the secondary slope meant. This measure serves to lower the temperature in the the knob-enclosed area of the filament. Alternatively, it can Be short-circuited by an inner pin.
  • the filament can also have an uncoiled connector.
  • a system of protuberances consists of three or four individual funnel-shaped knobs lying in one plane. In particular In some cases, five or more knobs can be advantageous.
  • Halogen bulbs pinched on one side is usually only one system needed. It is important to ensure that the return runs between the individual knobs of a system. It can preferably between two knobs.
  • Two-sided squeezed Halogen incandescent lamps are usually at least two, often three or more systems are used.
  • the individual piston segments between the systems can be cylindrical or especially when using coatings be bulged, for example as a barrel body or ellipsoid.
  • the pump handle can either be in the level of a system between there are two knobs or it is attached outside the system levels.
  • the invention can also be used for pumps without a pump rod Lamps are used.
  • knobs There are basically two embodiments of the knobs.
  • the knobs In a In the first embodiment, the knobs only enclose the filament loose without touching it. The distance between the knob and Luminous body very small, so that the luminous body is moving is severely restricted, but not firmly fixed.
  • knobs touch the luminous element and fix its connector directly, similar to the Bridge technology.
  • “Touching” means that the knobs on the filament either touch only on the periphery in a first variant or him in a second variant by touching the inner one Fully enclose the nub ends or even squeeze them completely, accordingly the web technology known per se.
  • the lamp according to the invention is much cheaper than Lamps with additional retaining rings.
  • the accuracy of adjustment of the filament is better than with the bridge technology.
  • the manufacture of the knob system is carried out by the piston the insertion of the filament and after squeezing the end or the ends are heated with three (or four or more) gas burners and is pressed in simultaneously with a corresponding number of stamps.
  • the knobs are designed so that the lamp body with respect to the piston axis its mobility in both the axial and radial directions is significantly restricted or fixed. Filament or sections of the filament, which is not aligned axially before the burling process were automatically adjusted during the manufacture of the knobs. Furthermore become luminous elements that ins during the lamp manufacturing process Vibrate and run the risk of being incorrectly fixed, now automatically brought into the correct position.
  • a particular advantage of the invention is that when used spaced knobs of the filament also only subsequently in the Piston can be introduced. The preforming and coating of Piston segments can therefore be carried out undisturbed.
  • Figures 1a and 1b show a double-sided squeezed and rocked Halogen light bulb 1 for general lighting with an output of 500 W, which is suitable for direct connection to the 230 V mains.
  • she has a cylindrical piston 2 made of quartz glass with an inner diameter of 7 mm and a total length of 105 mm. In the middle is a pump tip 3 attached. The two ends of the piston are each with one Pinch seal 4 closed.
  • the piston 2 is argon with the inert gas filled, to which a known halogen additive is added.
  • An axially arranged filament 5 is in luminous sections 6 and connectors 7 divided.
  • the filament is simply coiled the pitch of the connectors being greater than that of the luminous ones Sections is selected. It is over two simply coiled power supplies 8, the slope of which is greater than that of the luminous sections, and via two sealing foils 9, which are embedded in the pinch seals are connected to the contacts of the ceramic base 10.
  • a total of three systems 11 of knobs 12 are at approximately the same intervals distributed over the length of the bulb and hold the filament 5 selectively, so that the ones in between or adjacent to the end luminous sections 6 do not sag and are well centered within four cylindrical piston segments 13 are arranged.
  • the piston segments 13 are separated from each other by the knob systems 11.
  • the halogen cycle process is not hindered by the systems 11 and the optical Properties of the lamp remain homogeneous.
  • Each system 11 exists from three knobs 12, which lie in a plane transverse to the lamp axis.
  • the Knobs 12 are funnel-shaped and at a mutual angular distance of 120 °, starting radially from the piston wall directed towards the light inside.
  • the funnels of the knobs are circular. However, because of the perspective representation in FIG. 1 distorted.
  • Fig. 2a shows a lamp pinched on two sides, which is essentially in construction corresponds to the version shown in Fig. 1, but which is bulged elliptically Has piston segments 15 and outside on the piston surface has an interference filter coating 19.
  • the filament 6 is through three knob systems 16 supported. Each system 16 consists of four knobs 17 at a mutual angular distance of 90 °. Because of the four knobs the funnels of the knobs 17 are somewhat shorter designed elliptically, for example by a correspondingly shaped Stamp can be achieved during manufacture.
  • the lamp is in itself in a known manner without a pump to achieve better optical properties.
  • FIG. 2b also shows a lamp pinched on both sides, which is under construction essentially corresponds to the version shown in FIG. 1. However, she points out cylindrical piston segments 13.
  • the filament is through three systems 16 'supported. Each system 16 'consists of six knobs 17' in mutual angular distance of 60 °. Because of the six knobs close to each other, the funnels of the knobs 17 'are strongly elliptical shaped.
  • the pump stem 18 is located in the middle of the last piston segment.
  • Fig. 3 shows a lamp 20 pinched on one side with a cylindrical one Piston 21 and an axial filament 22 through two power supplies 29, 31 is connected to foils 30.
  • the filament has two simply coiled luminous sections 23 and one in between uncoiled connector 24.
  • a single system 25 of three knobs 26 across Lamp axis arranged.
  • the end distant from the pinch 27 28 of the luminous element is connected via the returning power supply 29 one of the foils 30 connected in the pinch 27.
  • the return 29 runs exactly between two knobs 26.
  • FIG. 4 shows a first embodiment for the implementation of Nubs according to FIGS. 1 to 3.
  • the cross section (FIG. 4a) at the level of the nub system 35 shows that the system is formed from three knobs 36 which extend up to extend to the filament 37 and fix it. Is dashed for the case of a lamp pinched on one side, a return line 29 is drawn in, the between two knobs 36 axially parallel on the piston wall 38 is led along.
  • FIG. 4b and 4c show the longitudinal and cross-section of a lamp bulb in the area of a knob system 40 with four reaching to the filament Knobs 41.
  • the luminous element 42 is simply coiled, the luminous section 43 is wrapped tightly while the connector 44 has a much larger slope and an inner pin 39 is short-circuited.
  • the luminous element 42 is both through the knobs 41 axially and radially fixed.
  • Fig. 4c is one-sided squeezed for the case The lamp 29 is drawn with a broken line. It is between the walls 45 of two adjacent knobs 41 are clamped.
  • FIG. 5 is another embodiment for the analog Knobs 46 shown.
  • the funnel of the knobs has on the outside, i.e. nearby the piston wall, a larger cross section than that shown in Fig. 4 Funnel.
  • the depression formed by the funnel is in the piston wall overall flatter.
  • the bottom 47 of the recess does not reach towards the luminous element 48, but ends shortly before that.
  • the dimensions of the knobs 46 and the lamp body 48 are matched to each other that anyway there is little freedom of movement for the filament.
  • the filament is so only limited in freedom of movement due to the knobs, but not fixed. By the minimum number of three knobs per system this restriction is sufficient, however, while a similar one System based on just two knobs facing each other, would be inadequate since the filament can move across the knobs remains.
