Definitions

  • the invention relates to a high-pressure discharge lamp according to the preamble of claim 1.
  • Such lamps are in particular high-pressure discharge lamps for general lighting or for photo-optical purposes.
  • the object of the present invention is to provide a high-pressure discharge lamp according to the preamble of claim 1, which is compact and yet has sufficient Platzertik.
  • the invention relates to space-protected lamps with two outer pistons in the entire power range.
  • the second outer bulb is a sheath, which serves as Platzertik for possible lamp destruction in case of negative influences.
  • the fixing of the outer bulb must be done so that the destruction of the lamp or other negative influences do not damage the outer bulb.
  • the outer bulb must also be protected against rotation to the base to ensure trouble-free switching on and off of the lamp.
  • the invention particularly relates to space-protected lamps with outer bulb and a sheath in the low-wattage power range to a maximum of 150 W.
  • the sheath serves as Platzerschutz for possible lamp destruction by negative influences.
  • the sheathing is in particular made of glass or plastic, in any case, it must be suitable for high temperatures and photometrically suitable.
  • the second outer bulb preferably made of hard glass, is fixed by deformation after a corresponding heating process in the pinch region of the base lamp, preferably with outer bulb made of quartz glass.
  • the two normally different glasses of the two outer pistons must not fuse (different coefficient of expansion).
  • a spring in the dome area provides the necessary bias of the base lamp in the outer bulb to avoid rattling or wobbling of the second outer bulb.
  • the attachment of the second outer bulb is relieved differently.
  • the second outer bulb is provided with side holes or holes at the level of the base.
  • the base has at these positions holes or recesses for receiving a pin-shaped fastening means, such as a split pin, rivet, pin, screw or the like.
  • the outer bulb is thus fixed by means of a split pin, rivet, pin, a screw or the like, which are driven from the outside through the hole / hole in the socket.
  • the attachment meets the requirements for the maintenance of the outer bulb on the base, as well as the anti-rotation.
  • a bias of the second outer piston achieved in that takes place before the pinning of the system, a compression of the spring washer by compressive force.
  • the fixation of the second outer piston takes place by the pressing of at least one pin or the like, preferably of two opposite pins or the like.
  • the compression spring or spring washer also known as a plate spring as known per se, is intended to prevent tilting and shaking of the second outer bulb on the support plateau.
  • the pins can be made of metal or plastic. This process is very time-saving and needs no additional process effort, such as kiting, melting or rolling.
  • the second outer bulb can in principle also be made of plastic, provided that it is sufficiently heat-resistant.
  • a suitable plastic for such a jacket is particularly, at least proportionally, polycarbonate, polyester, poly-methyl methacrylate or polyolefin.
  • transparent, UV-stable, high-temperature-stable plastics, in particular Teflon, PTFE are particularly suitable.
  • FIG. 1 shows the structure of a high pressure discharge lamp 1 highly schematic. It has as base lamp a discharge vessel 2, which is housed in an outer bulb 3. The outer leads 4 of the discharge vessel, the Contact electrodes inside are connected to two frame wires 5 and 6. A short frame wire 5 leads to a first foil 7 in a pinch 8 of the outer bulb. A long frame wire 6, often called stirrup wire, leads to a second film 7 in the pinch 8.
  • the discharge vessel 2 has at its ends in each case a capillary 10, as known per se, and a filling of an ionizable gas, usually argon or Xenon, mercury and metal halides, also known per se. Two electrodes are located in the interior of the discharge vessel, as also known per se, and not shown here.
  • the outer bulb 3 is surrounded by a second outer bulb or casing 15 made of hard glass, which bears tightly against the Au ⁇ enkolben 3.
  • This second outer bulb 15 is made of tempered glass, while the inner outer bulb 3 is made of quartz glass.
  • the attachment of the second outer piston 15 takes place directly on the first outer bulb 3 approximately at the level of the pinch seal 8 by a "gentle" pinch 16. This is meant a positive fit of the outer bulb, initially leaving a small clear distance.
  • the outer bulb 3 of the base lamp in the dome 18 of the second outer bulb by a conically downwardly widening spring 19 or similar. centered, as is known. A final fixation of the outer bulb takes place by the spring force of the spring 19th
  • FIG. 2 shows an embodiment that takes into account the high temperature load in an improved manner. It is in the side view of FIG. 2a the second outer piston 20 with a socket-side cylindrical Opening 21 provided.
  • the second outer bulb 20 is placed on a stop 22, which projects laterally on the base 23. He is attached there by means of a splint 24, see FIG. 2b ,
  • the second outer bulb has a hole 25 through which the split pin 24 is inserted into a recess 26 of the base.
  • FIG. 3 is similar in construction FIG. 2 , However, here in the region of the stop 22, an annular plate spring 30 on the base edge, which serves as a stop 22, placed on which in turn rests the opening 21 of the second outer bulb.
  • the spring force of the plate spring 30 allows a pressing of the second outer piston 20 on the stop 22 of the base, wherein the second outer bulb is fixed in the pressed state by means of two mold pins 33.
  • glass for the second outer bulb 20 are all possible glasses, such as soft glass or quartz glass, in particular, is suitable as hard glass borosilicate glass, etc.
  • the discharge vessel 2 need not be made of ceramic, it can also be made of quartz glass or similar. be made.
  • a high-pressure discharge lamp has a ceramic discharge vessel which is accommodated in an outer bulb, wherein the outer bulb is also surrounded by a second outer bulb as splinter protection, which bears tightly against the outer bulb.
  • the outer bulb is socketed on one side and the discharge vessel is equipped with two ends.
