Definitions
- the invention relates to a metal halide high-pressure discharge lamp according to the preamble of claim 1.
- Metal halide high-pressure discharge lamps of this type are used in particular in lighting systems for stage, film and television, where light with color temperatures between 4000 and 9000 K and very good color rendering is required in all color temperature ranges. Recently, these lamps have also been used in projection technology and effect lighting.
- the object of the invention is to provide a metal halide high-pressure discharge lamp which emits radiation with a color temperature between 4000 and 9000 K and a general color rendering index Ra of greater than 90, the color rendering index R9 for the red spectral range in particular reaching values of 50 and more.
- Color rendering can be further improved by using hafnium and / or zirconium as metal for the metal halide filling, values between 50 and 98 being achieved for the red rendering index R9 depending on the lamp type.
- the general color rendering index Ra always has values of over 90.
- the lamp bulb when the lamps are operated on a dimmer, the lamp bulb no longer shows any blackening.
- the color rendering index no longer drops with decreasing performance, so that good color rendering values are also achieved here.
- the hafnium and / or zirconium increases the burning voltage, which makes it possible to shorten the electrode spacing with the same mercury dosage in order to obtain higher luminance levels.
- the lamps with hafnium and / or zirconium filling have reduced devitrification.
- the discharge vessel contains 0.02 to 6 mg hafnium per ml of the vessel volume.
- the filling should advantageously contain 0.01 to 4 mg of this metal per ml of the vessel volume.
- Iodine and bromine in a molar ratio between 0.2 and 5 are advantageously used as halogens.
- the discharge vessel should also contain cesium in an amount of up to 4 mg per ml of the vessel volume.
- the discharge vessel can additionally contain one or more rare earth metals as well as nickel and / or cobalt.
- the discharge vessel 2 made of quartz glass has a spherical shape and, at two diametrically opposite locations, has a neck 3, 4, into which pin-shaped tungsten electrodes 5, 6 are melted by means of sealing foils 7, 8 made of molybdenum. The ends of the sealing foils 7, 8 facing away from the discharge space are welded to power supply lines 9, 10.
- Table 1 below shows two different fillings of the discharge vessel 2 of a 400 W lamp, one with hafnium and one with zirconium, as well as the photometric data obtained with the respective fill.
- Table 1 Filling 1 Filling 2 J2 1.70 mg 1.10 mg Br2 0.84 mg 1.28 mg Cs 1.10 mg 1.10 mg Hf 1.80 mg --- Zr --- 0.48 mg Ed 11 mg 11 mg Ar 300 mbar 300 mbar Power consumption 400 W. 400 W.

- FIG. 2 shows a metal halide high-pressure discharge lamp 13 according to the invention with a base on both sides and having a power consumption of 575 W.
- the discharge vessel 14 made of quartz glass has an essentially spherical shape and has a neck 15, 16 at two diametrically opposite locations.
- a pin electrode 17, 18 made of tungsten is melted into each of these necks 15, 16 in a gas-tight manner via a molybdenum sealing film 19, 20.
- the sealing foils 19, 20 are electrically connected to a base of the type SFc 10-4, the base sleeve 21, 22 of which is attached to the free end of each neck 15, 16.
- a threaded pin 23, 24 is welded onto the base sleeve 21, 22, on which in turn a knurled nut 25, 26 is screwed.
- the electrical connection to the mains or ballast is established by connecting cables which are clamped between the base sleeve 21, 22 and the knurled nut 25, 26.
- Table 2 below shows two different fillings of the discharge vessel for a 575 W lamp, one with hafnium and one with zirconium, as well as the lighting data of the lamps.
- Table 2 Filling 3 Filling 4 J2 0.90 mg 0.90 mg Br2 0.60 mg 0.60 mg Cs 0.30 mg 0.30 mg Dy 0.40 mg 0.40 mg Hf 0.40 mg --- Zr --- 0.20 mg Co 0.05 mg 0.07 mg Ed 42 mg 46 mg Ar 400 mbar 400 mbar Power consumption 575 W. 575 W.

- FIG. 3 shows a metal halide high-pressure discharge lamp 27 according to the invention with a power consumption of 4000 W.
- the lamp 27 consists of an ellipsoidal discharge vessel 28 made of quartz glass, at the two ends of which lie in the axis, a neck 29, 30 made of quartz glass is melted on.
- a molybdenum sealing film 31, 32 is melted into each of the necks 29, 30, a pin-shaped electrode 33, 34 being provided on the end of the film 31, 32 facing the discharge vessel is welded from tungsten.
- the other ends of the sealing film 31, 32 are electrically connected to the bases 35, 36 of the type SFa 21-12, which are inserted over the free ends of the necks 29, 30 and fastened by means of putty.
- Table 3 shows two different fillings of the discharge vessel of a 4000 W lamp, one with hafnium and one with zirconium, as well as the lighting data of the lamps.
- Table 3 Filling 5 Filling 6 J2 1.30 mg 1.30 mg Br2 2.30 mg 2.30 mg Cs 1.20 mg 1.20 mg Dy 0.95 mg 1.10 mg DG 0.55 mg 0.40 mg Hf 0.27 mg --- Zr --- 0.14 mg Ed 235 mg 220 mg Ar 400 mbar 400 mbar Power consumption 4000 W 4000 W Discharge tube volume 24.5 ml 24.5 ml Electrode gap 20 mm 20 mm Burning voltage 200 V 200 V Color temperature 6000 K. 6000 K.
