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.

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.

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.
