Definitions
- the invention is based on a metal halide discharge lamp with a long service life according to the preamble of claim 1. It is in particular around metal halide discharge lamps for the field of application of effect lighting, i.e. with color temperatures above 5000 K and medium Arc lengths.
- the service life is at least 1500 hours.
- a metal halide discharge lamp with a long service life (at least 1500 hours) is already known, which is suitable for a wall load above 30 W / cm 2 .
- the filling contains the metals Li, In, Tl and Sn for use in effect lighting (over 5000 K color temperature). Na and rare earth metals are deliberately avoided as these are problematic for the quartz glass discharge vessel.
- the disadvantage of this filling is the limited wall load. At high wall loads above 50 W / cm 2 there is a strong drift in the color temperature due to diffusion of the small-atom Li through the wall of the discharge vessel.
- EP 492 205 is a metal halide lamp for effect lighting known as metals hafnium u./o. Zircon used. Otherwise only cesium, rare earth metals and cobalt or nickel are used as additives. Though becomes a good color rendering (color rendering index Ra> 90) and a good one Red rendering (R9> 90) achieved. However, the lifespan is only around 500 up to 750 hours
- Such lamps are preferably used for luminaires for architecture and Effect lighting, in particular for ambient lighting highlighting and intensifying accent lighting in limited areas, e.g. in House and apartment, in galleries or at events.
- the optical properties of light, especially localization the generation of light, the luminous flux related to the lamp power and the color temperature demands placed between the area of general lighting and special requirements, such as projection are.
- Li is replaced by one or more of the components Hf, Zr and Ta can be.
- the proportion of these lithium substitutes is preferably between 0.2 and 4.0 ⁇ mol / ml selected.
- the invention assumes that devitrification, that is, increasing crystallization the bulb of a metal halide discharge lamp essentially its Lifetime determined.
- the invention therefore sees a filling without a rare earth element because the rare earth elements are the main cause of the devitrification phenomenon have turned out with increasing operating age of the lamp.
- Dispensing with a rare earth element has an additional beneficial effect - in addition to extending the lifespan through lower devitrification - also result in a reduced tendency of the lamp to blacken on the inner wall of the bulb.
- the invention uses a filling which, in addition to the conventional components of ignition gas, mercury, halogen, indium, thallium and tin, contains the lithium substitutes hafnium, zirconium and tantalum individually or in combination.
- the lithium substitutes are responsible for the red component, while indium is responsible for the blue component and thallium for the green component in the radiation from the lamp. All of these elements essentially emit spectral lines, while tin is used to create a good continuum between the lines.
- this filling composition develops its optimal effect (long service life and good maintenance with good lighting values) only from a wall load of 50 W / cm 2 .
- Lamps with a color temperature of over 5000 K are preferred, better above 6000 K.
- the arc length of the respective lamp power is accordingly in the middle area; in particular, that related to the arc length specific output between 50 and 90 depending on the embodiment W / mm.
- Preferred halogens are the conventionally known elements iodine and bromine, i.e. the metals mentioned indium, thallium and tin as well as the lithium substitutes are added to the lamp as iodides and / or as bromides. Furthermore, part of mercury may added as iodide or bromide to excessive piston blackening to avoid. So it can be elemental and / or mercury be added as a halide.
- the invention finds a useful field of application in the performance range of 200 to 2500 W per lamp, but can also be used outside of these ranges become. As already explained at the beginning, it is particularly suitable for the Effect light market, in which somewhat lower demands on the color locus and the Luminance than in special applications such as in the film area or projection area be put. On the other hand, it makes itself felt in the effect light area the significantly improved service life as an economically significant advantage noticeable.
- the outer bulb can e.g. can also be advantageous as protection against contact, for example if an inner piston provided with two on opposite sides in a lamp to be connected on one side only. Then someone has to of the two connections of the inner piston on the outer wall of the inner piston are guided along to the other side, using an outer bulb as protection against accidental contact is appropriate. Finally, the improved explosion protection can be a reason for choosing a lamp with an outer bulb.
- the spatial-physical design is conventional and corresponds, for example the form explained in EP-A 492 205. The corresponding revelation is hereby referred.
