Definitions
- the invention is based on a high-pressure discharge lamp according to the preamble of claim 1.
- These are in particular metal halide lamps, especially one-sided versions. But also high pressure sodium lamps or high-pressure mercury discharge lamps are suitable.
- EP-A 566 975 already discloses a high-power discharge lamp of high power known in which a discharge vessel by means of a frame in an outer bulb is supported. At least one power supply to the discharge vessel is included a frame part electrically connected.
- It is an object of the present invention to provide a high-pressure discharge lamp provide the preamble of claim 1, which is a reliable and heavy-duty Has connection between electrically conductive parts and thus a enables extended service life.
- nickel and / or zircon is now used as a solder between those to be connected electrically conductive parts used.
- the thermal load on the solder joint is significantly reduced because the transition resistance is very low. This makes it easy to make extensive contact with the lamp parts to be connected achieve.
- the contact area is larger by at least a factor of 10 when welding.
- This technique is particularly applicable to parts made of molybdenum, since nickel is combines well with molybdenum. This technique is also suitable when the diameter the parts are relatively large, in particular larger than 2 mm. With those to be connected Parts are often wires with a diameter of 1 to 5 mm.
- the pure nickel (or zircon) solder is first used as a ring-shaped wire or applied as a cylinder and then heated. Its melting point is more than 1300 ° C (Ni: 1450 ° C; Zr: 1850 ° C).
- the solder joint is preferred by Induction manufactured. It is advantageous if there is extensive contact between the two parts to be connected by wrapping the first part with the second part is produced.
- the present invention relates to a high-pressure discharge lamp electrical cables and with an outer bulb in which a discharge vessel is held by means of frame parts, at the ends of the discharge vessel Power leads are brought out.
- At least one connection between two Lines, hereinafter referred to as first and second electrically conductive feed, is made by a solder joint that uses nickel and / or zircon as solder.
- the first feed is a frame part and the second feed is a Power supply.
- the connection can also be on two frame parts or obtain different parts of a power supply or feedthrough.
- Solder connection can any number of connections within the lamp or in Base area outside the outer bulb of the lamp by the invention Solder connection to be realized.
- the leads are usually wires (or pins or rods) with one Diameter up to 7 mm.
- a practical lower limit is 1 mm. But also different designed parts (for example sheets) can be connected to other parts become.
- At least one, preferably both feeds are made of molybdenum. Because Molybdenum forms a particularly intimate connection with nickel and / or zircon.
- the operating current is Lamp more than 20 A. Currents of 100 A can also be coped with.
- connection according to the invention is of great importance in the case of a lamp in which a discharge vessel sealed on two sides in an outer bulb with a base on one side is supported by a frame.
- Figure 1 shows a metal halide lamp, partly in section
- FIG. 1 shows the structure of a socket on one side according to the invention High pressure discharge lamp shown.
- High-pressure discharge lamp is a metal halide lamp for photo-optical Purposes with a power consumption of 6 kW.
- the high-pressure discharge lamp has a discharge vessel that is closed on both sides 1 made of quartz glass, in which an ionizable filling gas and two electrodes 2 are enclosed are.
- the discharge vessel 1 is evacuated by means of a two-part frame 3, 4 (or also filled with nitrogen), outer bulb sealed on one side 5 supported.
- the outer bulb 5 is essentially axially symmetrical. Its close to the base End 6 is cemented in a ceramic base 7.
- the base 7 has one High voltage strength of more than 70 kV.
- a long frame bracket 3 runs along the discharge vessel 1 to the base, dome-shaped end 8 of the outer bulb and is there with a power supply 9, which is led axially out of the discharge vessel by means of two turns 10 connected. In the area of the turns, the power supply and the bracket are included Nickel solder 11 soldered. This power supply 9 remote from the base is in a pump connection 12 fixed in the dome 8 of the outer bulb.
- the long bracket 3 is partially from a quartz glass tube 13 encased in an extension tube 20 near the base End 6 of the outer bulb 5 is inserted.
- a short frame bracket 4, which is parallel to the long bracket, is similar 3 is arranged, surrounded by a quartz glass tube 14 and in the end near the base 6 supported.
- the bracket 4 is with the end 6 near the base of the discharge vessel led out power supply 15 connected by the wire here of the bracket 4 is wound around the power supply 15.
- Nickel solder 16 soldered in the area of the connection point.
- the brackets 3, 4 made of molybdenum are each with solid strands 17 with contact pins 18 connected at the end of the base.
- the cavities inside the base are covered with a high-voltage resistant ceramic potting compound 19 filled.
- This lamp achieved in comparison to an identical lamp with spot welding as a connection between power supply and frame bracket more than 300% longer lifespan. Instead of 150 hours, more than 600 hours are achieved.
