Definitions

  • the invention relates to a metal halide discharge lamp according to the Preamble of claim 1. It relates in particular to a metal halide discharge lamp for the area of application of effect lighting, i.e. With Color temperatures above the so-called "daylight" temperature of 4200 K and with medium arc lengths.
  • Such lamps are preferably used for luminaires for architectural and effect lighting, in particular in relation to the ambient lighting prominent and enhanced accent lighting limited areas, e.g. in the house and apartment, in galleries or at Events.
  • the optical properties of light in particular to the location of the light generation, to the luminous flux related to lamp power and color temperature Requirements placed between the general lighting area and special requirements, such as projection are.
  • DE-A-3 242 752 discloses a metal halide discharge lamp which specifically to replace halogen lamps with color temperatures in the range of 3200 K ⁇ 200 K is suitable. Contains the discharge vessel of the lamp in addition to argon, mercury and iodine, the other filling components Indium, sodium, lithium, tin and thallium. The goal is with this lamp Color temperatures in the range from 3000 K to 4600 K and color rendering indices reachable from over 90.
  • US-A-3 852 630 is a metal halide discharge lamp with satisfactory color rendering even in to provide the red region of the spectrum. It should be used Disadvantage of lithium iodide - namely a relatively short lifespan the lamp (a few hundred hours of operation) - should be avoided. To solve this task, a filling with the components noble gas, Mercury, iodine and sodium, calcium, thallium and indium are proposed.
  • US A-4 360 758 discloses a high metal halide discharge lamp Luminous efficacy and good color rendering.
  • the filling components are noble gas, Mercury, iodine and thallium, calcium, tin and indium.
  • the invention is based on the technical problem with a metal halide discharge lamp according to the preamble of claim 1, the life to increase.
  • the invention assumes that devitrification, ie increasing Crystallization of the bulb of a metal halide discharge lamp essentially determines their lifespan.
  • the invention therefore sees a filling without a rare earth element because the rare earth elements prove to be essential Cause of the devitrification phenomenon with increasing operating age have exposed the lamp.
  • the described effects of the invention can be realized with a Filling, in addition to the conventional components, ignition gas, mercury and halogen containing lithium, indium, thallium and tin.
  • Lithium provides the red component, indium the blue component and thallium for the proportion of green in the radiation from the lamp. All three elements shine essentially spectral lines, so that tin is used according to the invention will, especially at low power and wall load realizing a good continuum between the lines.
  • Lamps with a color temperature of more than 4800 K, more preferably more than 5000 K are preferred.
  • the arc length of the respective lamp power is in the middle range; in particular, the specific power based on the arc length can be between 40 and 80 W / mm depending on the embodiment.
  • a preferred range for the reduced wall load which is possible on the basis of the invention, as explained above, is between 30 and 60 W / cm 2 .
  • the lamp filling contains no sodium. Prefers is, in particular, that apart from the above no other Ingredients in the filling are present from the usual traces apart.
  • Preferred halogens are the conventionally known elements iodine and Bromine, i.e. the metals mentioned lithium, indium, thallium and tin added to the lamp as iodides and / or as bromides. conventionally, if part of the mercury is added as iodide or bromide, to avoid excessive lamp blackening. According to the invention This gives the additional advantage that this measure in the lamp fill is unnecessary. So it can be the mercury elementary and the halogen with respect to the halides of the elements Lithium, indium, thallium, tin sourced stoichiometrically or only in form the halides of these four elements can be added. This results in the production the advantage that at least one component is less, namely the mercury iodide, bromide or generally halide.
  • the invention finds a useful field of application in the field of performance from 200 to 2500 W per lamp, but can also be outside of these ranges be applied. It is suitable, as already explained at the beginning, especially for the effect light market, in which slightly lower requirements to the color locus and the luminance than in special applications as placed in the film area or projection area. In contrast, however, the significantly improved service life is particularly evident in the effect light area noticeable as an economically significant advantage.
  • lamps are often with an additional outer bulb fitted. You can choose between the outer and inner pistons instead of a vacuum, special gas fillings are also used come.
  • the invention is in the same way for lamps with or suitable without outer bulb.
  • the outer bulb can e.g. can also be advantageous as protection against contact, for example if an internal piston provided with two internal pistons on opposite sides be used in a lamp that can only be connected on one side should. Then one of the two connections of the inner piston must be on the The outer wall of the inner bulb is guided to the other side, an outer bulb is attached as protection against contact. Finally Improved explosion protection can also be a reason for choosing one Be a lamp with an outer bulb.
  • a 300 W lamp has an average arc length of 5 mm. It is for the Operation designed without an outer piston and has a piston volume of 1.1 ml. Using an outer bulb would increase the Wall temperature slightly lowered the color temperature. To compensate the wall load is reduced (i.e. the lamp power is reduced or the inner bulb increases) and / or the proportion of lithium iodide decreases, to get the desired color temperature value. This is in present example 5500 K.
  • a luminous flux of 21 klm was achieved with this lamp.
  • the lifespan is over 2000 hours.
  • Another 300 W lamp has an average arc length of 5 mm. She is designed for operation without an outer piston and has a piston volume of 1.5 ml. The color temperature is 6100 K.
  • a luminous flux of 22.5 klm was achieved with this lamp.
  • the lifespan is also over 2000 hours.
  • the spatial-physical design is conventional and corresponds for example the one in the European patent application with the application number 91 120 910.4 and publication number 0 492 205 A2 Shape.
