Definitions

  • the invention is based on a lamp, in particular a high-pressure discharge lamp, according to the preamble of claim 1. It is in particular around metal halide lamps, high pressure sodium lamps or halogen incandescent lamps one-sided crushing and ceramic base, but also with incandescent lamps conventional screw base.
  • a high-pressure discharge lamp is already known from EP-A 261 722, in which the base is attached to the outer bulb with putty.
  • This technique is time, energy and Material-intensive, because the putty has to be heated out for a long time and additionally an inner part (steel band) is used for inductive heating.
  • an inner part steel band
  • problems arise under high loads because cracks can form in the putty and Harden areas of the putty differently.
  • stitch can arise that there can occur tropical-like conditions, who are not up to the usual putty.
  • the Common putty is sensitive to extreme environmental conditions. For example it tends to corrode in salty or sulphurous air.
  • the lamp according to the invention has a glass bulb, which has a longitudinal axis and is usually closed by a pinch is.
  • This bulb is often the outer bulb of a discharge lamp or a halogen incandescent lamp made of quartz glass or tempered glass. He can also be the only bulb of a discharge lamp or incandescent lamp.
  • a metal spring preferably made of spring steel.
  • the base has a trough-shaped receptacle that is loosely adapted to the crushing.
  • the metal spring is bent in a U-shape. It consists of a base part and two legs that grip the bruise. The attachment of the base on Piston is mediated by a double spring action of the spring.
  • the metal spring is a stamped sheet metal part or the like, which is bent into a U. During installation the metal spring is first pushed onto the pinch. It stops there particularly good if the contact surface (mostly on the broad side, but also the Narrow side is possible) has a ribbed structure. The distance should also be between the two legs before installation in the base slightly lower (in particular about 5 to 10%) than the assigned pinch thickness. Consequently sufficient provisional hold of the metal spring on the pinch is created.
  • the largest transverse extension of the metal spring i.e. the distance between them most distant parts of the two legs, at this time, So before installing the base, slightly larger than the assigned width the inclusion in the base.
  • the transverse expansion of the metal spring is advantageous by approx. 5 to 20% larger than the transverse extent (i.e. the width) of the socket.
  • this corresponds to a transverse expansion of the metal spring, which is about 0.3 to 1 mm larger than the transverse extension of the socket base is.
  • a simple realization of the double spring action is that at least a leg, preferably in the direction of the transverse extent, trough-shaped, in particular is V-shaped in cross-section, bent inwards or outwards.
  • the voltage the gutter conveys the spring effect after installation of the base.
  • the gutter can also be rotated by 90 °, ie aligned in the direction of the longitudinal axis his.
  • the metal spring is advantageously constructed so that it has two symmetrical legs owns. This halves the spring travel to be covered by each leg, whereby the material is used less. It also makes it symmetrical Placement of the piston in the base with respect to the longitudinal axis guaranteed.
  • the legs are asymmetrical, with only one Leg is channel-shaped, while the second leg with lateral Ends that are curled. They serve for an exact lateral fixation.
  • the base part of the metal spring advantageously runs at a distance from the power supply lines in the middle between the two power leads. This distance comes special Significance in high-pressure discharge lamps, in which an ignition voltage of several kV may be required. Therefore, is a special in these cases narrow base part to use to prevent arcing between a power supply and to avoid the base part. It is beneficial if the distance of the base part is too each power supply is at least 3 mm.
  • the lower edge of the extension is preferably at least 2 mm from here the power supply lines spaced. Because a rollover should also go in this direction be avoided. If possible, at least 1 mm air gap. This means that the bottom edge of the attachment is not direct abuts the bruise, but is spaced from its broad side.
  • the free outer end of the leg in the receptacle is at least 2 mm ends below the top edge of the base.
  • the fastening technology presented here has a very special advantage the base of new metal halide lamps with ceramic discharge tubes as well as high pressure sodium lamps. Because here the discharge vessel is closed on both sides for technical reasons, these lamps have an unusual large ratio of length to diameter of the outer piston. While in conventional metal halide lamps this ratio is about 2: 1 to 3: 1 ceramic metal halide lamps (and high pressure sodium lamps) possibly a length to diameter ratio greater than 3: 1. It has emphasized that when installing these lamps in the corresponding version (or Lamp) the tendency to jump in the pinch of the outer bulb considerably increases when the base is fixed with putty. The cause is that the putty is a rigid connection between the outer bulb and base mediated.
  • a metal halide lamp with an outer bulb 1 is shown in FIG Tempered glass (or quartz glass) that has a longitudinal axis and one side through a well-known double T-shaped (sometimes also called L-shaped) pinch 2 closed is.
  • a discharge vessel 10 is squeezed on one side in the outer bulb made of quartz glass with a filling of metal halides.
  • the base 5 is attached to the pinch 2 by means of a metal spring 6.
  • the base 5 has a trough-shaped, loosely adapted to the pinch 2, approximately rectangular Recording 7 with indentations 21 on the broad sides.
  • the metal spring 6 is U-shaped bent. It consists of a base part 11 and two free legs 12, 13, which together encompass the bruise.
  • the base part 11 is at the bottom End of the pinch 2, while the legs 12, 13 rest on the broad sides 8.
  • the broad sides 8 of the bruise 2 are over a large part of their area corrugated (only partially shown under reference number 14).
  • the width of the base part 11 corresponds to approximately one third of the distance between the power supply lines 3.
  • the metal spring 6 is shown again in detail in different views. It consists of spring band steel with a thickness of 0.3 mm.
  • the first, narrow leg 12 is trough-shaped inwards transversely to the longitudinal axis, that is to say second leg, bent.
  • the channel 15 forms two legs 15a, 15b the shape of a V (or U). Your inner leg 15b is over with the base part Attachment 16 connected.
  • the second, wide leg 13 of the metal spring is T-shaped constructed so that a widened surface 18 on a narrow neck 17 sits.
  • the side ends 19 of the surface 18 are rolled into a three-quarter circle. she fit exactly into the space between the widened narrow sides 20 the pinch and the central indentation 21 on the broad side of the base ( Figure 1c).
  • the metal spring 6 is centered exactly in the center.
  • the attachment of the base is mediated in that the leg 12 with his Channel 15 in the narrow gap 22 between the recess 21 of the receptacle and the pinch 2 is clamped.
  • FIG. 3 shows a metal halide lamp with an outer bulb 22 Quartz glass (or tempered glass) that has a longitudinal axis and one side through a Pinch 2 is closed.
  • the length L of the outer bulb is 7.5 cm
  • the outer diameter D is 1.8 cm
  • the ratio L / D 4.2.
  • a ceramic double-ended discharge vessel 23 is also in the outer bulb a filling of metal halides used.
  • the base 5 is attached to the pinch 2 by means of a metal spring 26.
  • the Socket 5 again has a squeeze 2 loosely adapted, approximately rectangular Recording 7.
  • the metal spring 26 is bent in a U-shape. It consists of one Base part 31 and two free, symmetrically constructed legs 32. The base part 31 rests on the lower end of the pinch 2, while the legs 32 the pinch reach around.
  • the width of the base part 31 is 5.5 mm and corresponds at least a third of the distance between the power supplies 3.
  • the distance the base part of each power supply is 3 mm.
  • the width of both legs is 32 only a little narrower than the broad side of the socket.
  • the thighs are bent in a channel-like manner transversely to the longitudinal axis, i.e. towards the bruise.
  • the metal spring 26 is shown again in detail. It consists of spring steel with a thickness of 0.2 mm.
  • the trough 35 forms from two legs 39a, 39b roughly the shape of a V (or U).
  • the two gutter legs 39a, 39b are however asymmetrical, since they are of different lengths and angles to the Are longitudinal axis.
  • the outer leg 39a forms a first angle of 45 ° to the Longitudinal axis, while the inner leg 39b is angled only about half as much (second angle of 23 °). This is because the outer leg is the real one Holds and therefore requires a higher spring force than the inner one Leg, whose task is the centering of the piston and protection against tilting is.
  • the first angle should preferably be chosen between 35 ° and 55 °, while the second angle is between 15 ° and 35 °.
  • the first angle is advantageously larger (by at least 20%) than the second, a ratio is preferred of about 2: 1.
  • the inner gutter leg 39b is connected to the base part 31 via an extension 36 connected.
  • the extension 36 is constructed so that 37 on a narrow neck a widened surface 38 sits so that it is approximately T-shaped overall.
  • the widened Surface 38 is bent approximately 45 ° to the outside on the inside of the gutter.
  • the lower edge of the crossbar of the T (surface 38) is spaced about 1 mm from the broad side of the pinch and a total of about 2.5 mm from the power supply 3 removed to avoid sparking during ignition.
  • the gutter 35 is approximately as wide as the widened area 38, that is, the crossbar of the T, the extension piece 36.
  • the attachment of the base is mediated by the fact that the two channels 35 in the narrow gap 29 between the indentation 28 of the receptacle and the pinch 2 are clamped.
  • the smallest distance between the two legs 32 is relaxed Condition 3.15 mm (see Figure 4a).
  • the distance at the seams between Extension 36 and inner gutter leg 39b is 6.0 mm. Between free ends of the outer legs 39a of the channel, the distance is even 6.2 mm.
  • the legs 39a, 39b are therefore not only asymmetrical, the outer leg is also spread further so that a stronger spring force can act here.
  • the width of the pinch (including corrugation 14) is measured on the broad sides, approx. 3.3 mm.
  • the width of the socket in the base The area of the indentation 28 is approximately 5.9 mm.
