Definitions

  • the invention relates to a method for operating an amalgam lamp, wherein the run-up time is reduced.
  • Amalgam lamps are extremely durable high-performance low-pressure lamps. They achieve up to 10 times the UV power density of classic low-pressure mercury lamps and can be used at higher ambient temperatures. In addition, amalgam lamps are insensitive to temperature fluctuations.
  • Typical applications for amalgam lamps include drinking water sterilization and process water treatment in industry, water disinfection in fish farming, but also disinfection of air in air conditioning and cooling systems and surface disinfection.
  • amalgam lamps In order to realize a quick start with the mercury low-pressure amalgam lamps, it is not sufficient to increase only the discharge current significantly compared to the operating current. In these lamps, most of the mercury is bound in the amalgam when cold. It is therefore necessary to specifically heat the amalgam deposit so that in this way can build up a significant mercury vapor pressure within the lamp quickly.
  • a heating element applied to the lamp is indicated in the form of a PTC or an ohmic resistance.
  • the heat transfer through the quartz to the amalgam is here, however, quite slow.
  • the heating element is provided here for controlling the amalgam temperature during operation, not to achieve a short burn-in time.
  • the patent document US-A-5 095 336 discloses a method according to the introductory part of claim 1. The object of the invention is therefore to provide a method for operating an amalgam lamp, in which the run-up time is significantly reduced and the lamp already after a few seconds unfolds its full effect, as well as for the method suitable amalgam lamp.
  • the method according to the invention for operating an amalgam lamp, wherein the amalgam lamp has at least one amalgam depot provides that the depot is heated by means of an external energy source. This heating causes the amalgam to liquefy within one second, quickly building up a significant mercury vapor pressure and quickly reaching full power after ignition. Thus, the baking phase is reduced to a few seconds. It has been shown that this fast-start behavior, especially in industrial processes in which discontinuous operation is desired, has great importance and burn-in phases of less than 10 seconds are desired.
  • the invention provides that an infrared lamp is used as the energy source.
  • the infrared lamp has a gold-plated reflector.
  • the infrared lamp is similar to a commercial halogen reflector lamp for general lighting.
  • the filament is imaged onto a focal spot of a few millimeters in diameter.
  • the infrared reflector lamp is placed over the amalgam lamp, that the focal spot is brought to coincide with the amalgam depot. This liquefies the amalgam within 1 second of turning on the infrared reflector lamp and builds up the desired mercury vapor pressure so that the lamp can quickly deliver its full power.
  • the amalgam lamp according to the invention provides a lamp tube filled with inert gas with two electrodes arranged in the lamp tube, at least one amalgam deposit being arranged on an inner side of the lamp tube.
  • an adhesion promoter layer can be applied, for example, of noble metal.
  • the adhesion promoter layer advantageously serves as a carrier layer for amalgam.
  • FIG. 1 a mercury low-pressure amalgam lamp 1 is shown, which has a lamp tube 10 with two electrodes 12 arranged in the lamp tube 10.
  • the interior 14 of the lamp 1 is filled with a noble gas or noble gas mixture.
  • the lamp tube 12 seals the interior 14 against the environment.
  • On the inside of the lamp tube 10 is optionally a bonding agent layer 16, which is formed in this case of gold or a gold alloy.
  • This adhesion promoter layer 16 serves as a carrier for the amalgam depot 18.
  • An external infrared lamp 20 with a reflector 22 is arranged next to the amalgam depot 18, so that the infrared radiation 26 on the Amalgamdepot 16 is focused. Before the ignition of the lamp 1, the amalgam reservoir 18 is heated and thereby released mercury vapor. This is the discharge already during the ignition available, so that sets immediately a significant UV power.
  • FIG. 2 the run-in behavior of a conventional mercury low-pressure amalgam lamp without amalgam heating is shown.
  • the electrodes preheated by a heating current after about 5 seconds at time A, the lamp is ignited.
  • the UV power at the beginning is extremely low and rises only slowly. Only after about 70 seconds has the lamp reached about 50% of the UV power and it takes about 140 seconds for the mercury low pressure amalgam lamp to reach its full UV output.
  • FIG. 3 shows the running-in behavior of a mercury low-pressure amalgam lamp according to the invention.
  • the electrodes are also preheated for 5 seconds, but at the same time the amalgam deposit is also preheated at the same time until time B at the same time. It can clearly be seen that the mercury low-pressure amalgam lamp reaches about 50 percent of the UV power within about 10 seconds and reaches its full UV power after about 30 seconds.
