Definitions
- the invention relates to a metal halide high-pressure discharge lamp with a medium bow performance between 60 and 140 W / mm arc length for the Installation in optical systems according to the generic term of claim 1.
- Metal halide high-pressure discharge lamps of this type are used in particular in projection (slide, overhead, narrow film and cinema projection) and glass fiber lighting systems (endoscopy, microscopy, effect lighting for film and television), where light with color temperatures between 4000 and 7000 K and good or very good color rendering is required in all color temperature ranges. They are characterized by a very short arc (a few mm) and maximum luminance (on average a few 10 kcd / cm 2 ), which makes them ideal for installation in reflectors or other optical imaging systems.
- EP 0 386 601 describes a metal halide discharge lamp for reprography and projection disclosed.
- the electrode spacing and the electrical power consumption is 5 mm or 100 W. indicated, from which an average arc power of 20 W per mm arc length results.
- the discharge vessel the lamp contains mercury, zinc, indium, Lithium, thallium, a halogen and a rare earth metal such as. Lanthanum, or scandium Dysprosium.
- U.S. Patent 4,229,673 is a metal halide discharge lamp disclosed with an outer bulb.
- an electrode distance of 43 mm is specified, corresponding to an average arc output of almost 10 W per mm arc length.
- the discharge vessel the lamp contains mercury, neodymium iodide and Cesium iodide and optionally additional sodium iodide.
- For installation in optical systems Lamp due to its outer bulb and the large one Electrode gap not suitable.
- the object of the invention is a metal halide high-pressure discharge lamp to create the one average lifespan of at least 1000 operating hours has a very short arc with very has high luminance and a color temperature between 4000 and 7000 K - with very good Color rendering - has.
- the metal halide high-pressure discharge lamp according to the invention is operated at specific arc powers between 60 and 140 W per mm arc length and comparatively low wall loads between 40 and 85 W per cm 2 wall area.
- bulb blackening or devitrification occurs after a short time with wall loads below or above approximately 60 W per cm 2 , the value for this limit varying depending on the cooling. This reduces the usable luminous flux and the lamp life is limited.
- the filling of the lamp according to the invention which consists of mercury, at least one noble gas and at least one halogen and cesium, is tantalum and dysprosium, advantageously added with a weight ratio between 0.3 and 1.5, the sum of the filling quantities of these two important additives advantageously is between 0.2 and 1.5 mg per cm 3 of vessel volume.
- Tantalum maintains the halogen cycle process even with relatively low wall loads and thus largely prevents blackening and devitrification of the bulb, so that a long average service life can be achieved. Tantalum also contributes to the continuum portion in the optical spectrum. With its multi-line spectrum, Dysprosium ensures a high radiation flow in the visible range of the optical spectrum.
- the addition of tantalum and dysprosium according to the invention thus minimizes the tendency to devitrification and blackening of the bulb - ie the average lifespan is extended accordingly - and the luminous flux and the color rendering are optimized.
- lithium can optionally be added in addition, up to 0.2 mg per cm 3 of vessel volume, which increases the red component of the radiation, which is particularly the case when the lamp is used in a dichroic cold light reflector Advantage can be that slightly increases the color temperature of the reflected radiation compared to the total radiation of the discharge.
- lithium is an atomic line emitter, which preferably radiates in the hot arc core and is therefore emitted particularly efficiently by correspondingly focusing special reflectors, which only depict the inner arc core.
- the discharge vessel can contain cesium up to 0.8 mg per cm 3 of vessel volume. Iodine and bromine are advantageously used as halogens in a molar ratio between 0.2 and 2.
- FIG. 1 In the figure is a metal halide discharge lamp according to the invention 1 with a power consumption of 400 W schematic (not to scale) shown how they are used in a reflector system can be.
- the discharge vessel 2 made of quartz glass has an essentially spherical shape Shape and points to two diametrically opposite Place a neck 3, 4 in each pin-shaped tungsten electrodes 5, 6 by means of sealing foils 7, 8 are melted from molybdenum.
- the ends of the sealing films facing away from the discharge space 7, 8 are with power leads 9, 10 welded when installed in a reflector system with the electrical connections in the reflector get connected.
- Table 1 shows two fillings according to the invention of the discharge vessel 2 of a 400 W lamp and the lifetimes achieved in each case as well as the lighting data of this lamp.
- the color temperature is reduced by approximately 500 K compared to filling 1.

- Another embodiment relates to a Metal halide discharge lamp according to the invention with a power consumption of 270 W. It differentiates differ in structure from that in the Lamp shown essentially only by one smaller discharge volume and a shorter one Electrode gap and is therefore not pictorial shown.
- Table 2 shows a filling of the discharge vessel of a 270 W lamp according to the invention and the lighting data of this lamp.
- Discharge tube volume 0.55 ml
- Power consumption 270 W.
- Wall load 81 W / cm 2
