Definitions

  • the invention is based on an electric lighting device for Producing saturated colors with at least two lighting units, wherein the lighting units each have a discharge vessel with a low-pressure discharge and a phosphor coating on the inner wall of the Own vessel.
  • the color locus of an incandescent lamp is in an undimmed state (location 1). and shown in dimmed state (location 2).
  • location 1 the color locus of an incandescent lamp
  • location 2 the color temperature
  • the light bulb decreases simultaneously with the illuminance also the color temperature, the light becomes "warmer", the proportion of the one emitted in the red spectral range Light grows.
  • the bulb thus shows a similar behavior like the daylight, the morning and evening both a lower illuminance as well as having a lower color temperature than noon.
  • the human eye and sensation are adjusted to it. That the Color temperature of Hg fluorescent lamps remains constant during dimming or even rising, however, is perceived as unpleasant.
  • the object of the invention is therefore to provide a lighting device, which avoids the disadvantages listed above.
  • the object is in the electric lighting device for generating saturated colors with at least two lighting units, the Lighting units each have a discharge vessel with a low-pressure discharge and a phosphor coating on the inner wall of the vessel have, solved by at least one lighting unit a Discharge vessel with a xenon filling and a dielectric barrier Discharge (Xe excimer discharge) has.
  • the Lighting units each have a discharge vessel with a low-pressure discharge and a phosphor coating on the inner wall of the vessel have, solved by at least one lighting unit a Discharge vessel with a xenon filling and a dielectric barrier Discharge (Xe excimer discharge) has.
  • LAP and YOB can be used in the Xe excimer lamp also other VUV excitable phosphors, such as alternative Tb-doped ones Green fluorescent and Eu-doped red phosphors are used, whose Emission radiation have a color location near the spectral color train.
  • suitable Phosphors are e.g. in WO94 / 22975.
  • the color locus of the lamp corresponds to that of the applied one Phosphorus, since the dielectrically impeded Xe discharge itself practical no visible radiation contribution contributed.
  • the Hg low-pressure discharge lamp does not match the color location of the lamp Color location of the applied phosphor match, since the Hg discharge a own color location in the visible (see Hgvis in Figure 1) has.
  • the discharge vessel with the Xe excimer discharge has advantageous on the inner wall of the discharge vessel, a phosphor coating for Generation of a red color spectrum.
  • the second lighting unit a discharge vessel with a Xe excimer discharge wherein the discharge vessel is a phosphor coating on the inner wall of the green spectrum generating vessel has:
  • the color locus for the blue portion of the color mixture is in use a discharge vessel with a Xe excimer discharge and a phosphor coating in the form of a barium magnesium aluminate: Eu only very little different from the color place, with a mercury discharge and the same phosphor coating is achieved, it is also conceivable here as Lamp unit instead of a Xe excimer fluorescent lamp a mercury fluorescent lamp to use.
  • the Xe excimer lamps can have any shape; they can, for example as a line radiator with a circular cross-section or as a surface radiator be executed.
  • the Hg low-pressure discharge lamps can as flashlights with different sizes, circular diameter or also as compact lamps with a multiply curved tube with circular Cross section be executed.
  • the discharge vessels of the units can have an internal Have reflector to allow a directed emission of radiation
  • the discharge vessels of the individual units can be single-sided or sockets on two sides.
  • the discharge vessels of the individual lighting units can by means of electronic ballasts are controlled and dimmed. Thereby is the setting of any color in the color triangle guaranteed.
  • the entire lighting unit can be designed as a lamp. Because the generated by the individual units radiation due to the different Color temperatures or colors must be mixed to allow the viewer a spatially uniform color impression receives, it is necessary the radiation in the luminaire is diffused at least once.
  • the Luminaire advantageously has a reflector and / or a diffuse cover on.
  • lighting device as a compact low-pressure discharge lamp with a central socket at one end, in which case the discharge vessels of the individual lighting units have to have the shape of a multiply bent tube whose Ends are merged and secured in the socket.
  • Figure 2a and 2b shows schematically a lighting device in the form a ceiling lamp with three lighting units in the form of each other arranged rod-shaped discharge vessels with a Xe excimer discharge (Xe excimer lamp), the uppermost, near the ceiling 4 arranged Xe excimer lamp R a red emitting phosphor coating, the middle Xe excimer lamp G a green emitting phosphor coating and the lowermost Xe excimer lamp B is a blue emitting phosphor coating having.
  • the each at the ends of the straight lamps located socket (not shown) are mounted in common sockets 5 and contacted.
  • the associated ballasts for operation and dimming of the Xe excimer lamps R, G, B are not shown here.
  • the mix of radiation of these three lamps is curved by two Reflectors causes, with a reflector 1 above the lamps on the ceiling 4 and a reflector 2 arranged below the lamps in the lamp are.
  • the light shown in Figure 3 corresponds essentially to the light from Figure 2.
  • the Xe excimer lamps R, G, B are not among themselves, but arranged side by side.
  • FIG. 4 shows a further embodiment of the luminaire shown in FIG. 2, wherein the Xe excimer lamps R, G, B - seen parallel to the ceiling 4 - in an equilateral triangle are arranged.
  • FIGs 5a and b is another lighting device according to the invention represented in the form of a lamp.
  • the lamp contains three here Lighting units in the form of U-shaped curved discharge vessels R, G, B each with an Xe filling, a dielectrically impeded discharge and a red or green or blue emitting phosphor coating, wherein the discharge vessels in a common base socket system 6 are merged.
  • the ballasts for operation and for Dimming the lighting units are housed in the base socket system 6.
  • the discharge vessels are rotationally symmetric about an axis arranged perpendicular to the ceiling 4 in the lamp. To mix the light the lamp has a reflector 1 at the top and a reflector 2 the bottom of the lamp.
  • the luminaire shown in FIG. 6 essentially corresponds to that in FIG. 3 shown light. Instead of the reflector at the bottom, this has Lamp but a diffuser 3 for diffuse mixture of the lamps emitted radiation.
  • the luminaire in FIG. 7 shows a further variant of that shown in FIG Lamp.
  • the lower reflector instead of the lower reflector here are the Xe excimer lamps R, G, B provided with internal reflector coatings 7.
  • the reflector coatings are arranged so that the votes of the lamps Radiation in cooperation with the reflector 1 at the top the lamp to the ceiling 4 undergoes optimal mixing. Additional can thereby, as shown in Figure 8; another diffuser 3 at the bottom be provided the lamp.
  • FIG. 9 shows a further variant of the luminaire for FIG. 6.
  • the three Xe excimer lamps here are twelve Xe excimer lamps with each a straight tubular discharge vessel and one alternately red R, green G and blue B radiation emitting phosphor coating arranged parallel to the ceiling 4. This results in a surface light, for mixing the radiation at the top of a reflector. 1 and on the underside of the lamp has a diffuser 3.
  • the lamp shown in Figure 10 largely corresponds to the light Figure 4. Instead of the three Xe excimer lamps is here but only one Rod-shaped Xe excimer lamp R with a red-emitting phosphor coating and a rod-shaped Hg low-pressure discharge lamp W with a red, green and blue or white emitting phosphor coating in the luminaire integrated.
  • FIG. 8 Similar to the light shown in FIG. 8, that shown in FIG. 8, that shown in FIG Light built. It has a rod-shaped Xe excimer lamp in the middle R with a red emitting phosphor coating and an internal Reflector coating 7 and left and right of which a rod-shaped Hg low-pressure discharge lamp W without reflector coating with a white emitting phosphor coating, wherein the discharge vessels each parallel to each other and parallel to the ceiling 4.
  • the lamp in Figure 12 is similar to that of Figure 11, wherein here in the middle of a rod-shaped Hg low-pressure discharge lamp W with a white emitting phosphor coating and to the left and right of it one staggered rod-shaped Xe excimer lamp R with a red emitting Phosphor coating and an internal reflector coating 7 are arranged.
