Definitions

the invention relates to a metal halide fill and associated lamp for a high-pressure discharge lamp according to the preamble of claim 1. It these are in particular fillings for lamps with warm white or neutral white light color.
the invention also relates to an associated filled therewith Lamp.
US-A 3,575,630 describes a lamp containing a metal halide filling with the elements Na, Tl, and Zr and has a warm white light color.
EP-A 883 160 lamp described. It has a metal halide filling with the elements Na, Sc, and other ingredients like Mn. This lamp is dimmable.
Metal halide discharge lamps with a glass discharge vessel and one Sodium-containing fillings are known to have the disadvantage of sodium diffusion the discharge vessel, which reduces the lamp life.
the sodium diffusion must take additional measures, such as shielding the power supply in the vicinity of the discharge vessel, reducing the manufacturing cost of the lamp elevated.
Another disadvantage of sodium-containing metal halide discharge lamps is their relatively low color rendering.
a filling for metal halide lamps is known from DE-A 35 12 757 which contains a metal silicide such as V 5 Si 3 .
the filling contains rare earth or Sc halide and the corresponding rare earth oxyhalide and / or Sc oxide.
the silicide acts here as a halogen getter.
FIG. 1 shows a color locus diagram of a metal halide lamp, which is based on two sides with a power of 250 W and a neutral white Filling (HQI-TS 250W / NDL from OSRAM) as an example, which contains a Na-containing metal halide filling has.
the performance of the lamp was measured on an electronic ballast reduced to half their luminous flux in steps of approximately 250W to 160W. As the power decreases, the color locus of the lamp moves out of range the straight line of Judd. The lamp becomes increasingly greenish.
a metal halide filling which consists of V and Mn halides consists. These can advantageously be combined with other halides of the elements Cs, Dy, Tl, Ho, Tm can be combined.
Another advantageous aspect of the invention is that the metal halide discharge lamp filled therewith is very well dimmable because the color locus changes with decreasing Performance takes place approximately parallel to the Planck curve and thereby high color rendering is retained.
FIG. 2 An embodiment of a 250 W metal halide lamp 1 is shown schematically in FIG. 2 shown. It comprises a discharge vessel 2 squeezed on both sides Quartz glass from a cylindrical evacuated outer bulb 3 made of tempered glass is enclosed, which is capped on one side. One end of the outer bulb 3 has a rounded tip 17, whereas the other end has a screw base 12 has.
a holding frame 6 fixes the discharge vessel 2 axially inside of the outer bulb 3.
the holding frame 6 consists of two lead wires, from which the one with the power supply 8 of the discharge vessel 2 near the base connected is.
the other lead wire is over a solid metal support wire, which extends along the discharge vessel 2, for the power supply remote from the base 9 led.
the discharge vessel 2 It also has a guide element 15 at the end near the base (in the form of a stamped sheet) and a support 13 near the top 17 in Shape of a partial circle.
the ends 4, 5 of the discharge vessel 2 have a heat reflective coating 16 provided.
On the support frame 6 is an additional welded onto a metal plate applied getter material 14.
the volume of the discharge vessel 2 is approximately 5.2 ml.
the distance between the electrodes 11 is 27.5 mm.
the discharge gas contains 56 mbar Ar as the base gas.
the discharge vessel 2 is preferably operated within an outer bulb 3, which is evacuated for particularly good color rendering. If the burner contains the Penning mixture mentioned above, an outer piston gas mixture with 600 mbar N 2 or 450 mbar CO 2 and an additional 50 mbar Ne is used to increase the service life.
FIG. 3 shows the spectrum of a lamp with a burning time of 100 h according to the exemplary embodiment according to FIG. 2, the discharge vessel of which contains 12.2 mg Hg and the metal halide filling according to Table 1. filling Metal halide content (% by weight) Total mass (mg) CsI Dyl 3 TII Get 3 Tml 3 Mnl 2 Vl 2 7.0 14.3 29.4 9.9 9.0 9.0 26.1 2.3
the lamp power is 247 W.
the lamp according to the exemplary embodiment thus has a significantly better color rendering as lamps with sodium-containing metal halide fillings and one around 5 Im / W higher luminous efficacy than lamps with Mn-containing metal halide fillings without V.
Fig. 4 shows the color locus of a lamp HQI-T 250W / NDL according to the above Embodiment according to FIG. 2, on an electronic ballast was operated. At 160 W the luminous flux reaches half the value of 250 W. According to Fig. 4, the color locus migration takes place with decreasing power of 250 W to 160 W approximately parallel to the Planck curve (a) and reaches the Daylight curve (b). The distances to the Planck curve and daylight curve are smaller than three threshold value units. The lamp remains white Light color.
5 and 6 show the general color rendering index Ra and special color rendering index R9 as a function of lamp power.
5 and 6 With decreasing performance 5 and 6 remain with the lamp HQI-T 250W / NDL with the Mn-V-containing Filling the general color rendering index Ra greater than 88 and the special color rendering index R9 greater than 54.
the lamp HQI-TS 250W / NDL decrease with the Na-containing filling the values for the general color rendering index 77 and the special color rendering index R9 to -48.
a ratio of Mn halide: V halide of 5: 1 to 20: 1 is preferred.
a filling containing the following proportions of metal halides is advantageous: Cs-Hal. 10 to 20% by weight, Dy-Hal. 25 to 35% by weight, TI-Hal. 6 to 12% by weight, Ho-Hal. 8 to 14% by weight, Tm-Hal. 8 to 14% by weight, Mn-Hal. 23 to 30% by weight and V-Hal. 1 to 4% by weight.
the halides of Cs, Dy, TlHo and / or Tm can be added. In order to have a measurable influence, one is recommended Minimum amount of 0.1% by weight.
