Definitions
- the invention relates to a metal halide high-pressure discharge lamp according to claim 1.
- Such lamps are characterized, among other things, by good to very good color rendering (R a ⁇ 90) and color temperatures in the range between approximately 4000 K and 7000 K. These values are achieved with light yields of typically more than 70 lm / W. These lamps are therefore suitable for general lighting as well as for special lighting purposes, for example projection technology, effect and stage lighting as well as for photo, film and television recordings.
- the electrical power consumption is between approx. 35 W and 5000 W. Typical power levels for general lighting are 150 W and 400 W. For special lighting, higher wattages are usually required, typically 575 W and more.
- the discharge tubes of the lamps are usually sealed on two sides, e.g. by means of crushing or melting and bypassing an outer bulb.
- versions sealed on one side are also possible.
- a long service life (typically 6000 h) is of further importance, particularly in its general meaning.
- the lamps for special lighting purposes are often used in combination with optical reflectors.
- the shortest possible arc lengths are sought in this case.
- the electrode distances are therefore only a few mm, typically less than 10 mm. With the corresponding power consumption, this results in significantly higher specific arc powers, typically between approx. 50 W and 100 W per mm arc length - compared to typically between approx. 10 W and 20 W per mm arc length for versions for general lighting purposes.
- the consequently higher wall loads promote premature devitrification of the discharge vessel and thus limit the service life to usually a few 100 hours.
- EP-A 0 391 283 discloses a metal halide high-pressure discharge lamp without an outer bulb for optical applications, which is also suitable for outdoor lighting.
- the power consumption is in the range between approx. 1000 W and 4000 W, with wall loads in the order of 30 W to 60 W per cm2 wall area of the discharge vessel and specific arc powers of approx. 67 W / mm.
- the discharge vessel contains a filling of argon (Ar) and mercury (Hg) as well as the rare earth metals (SE) per cm3 discharge volume dysprosium bromide (DyBr3, 1 ⁇ mol) and thulium bromide (TmBr3, 0.5 ⁇ mol), also 1 ⁇ mol thallium bromide, TlBromide (TlBromide) (CsBr) and 0.5 ⁇ mol thorium iodide (ThJ4).
- the thorium (Th) can be replaced by hafnium (Hf).
- EP-A 0 492 205 discloses a high pressure metal halide discharge lamp for optical applications. Typical power levels are 400 W, 575 W and 4000 W, with arc powers from approx. 95 W to 200 W per mm arc length.
- the disadvantage is the short lifespan of only approx. 300 h.
- Another filling system uses cobalt (Co) and / or dysprosium (Dy) and gadolinium (Gd). However, the service life is only approx. 500 h.
- the invention has for its object to eliminate the disadvantages mentioned and to provide a metal halide high-pressure discharge lamp which has a color temperature between 4000 K and 7000 K, a color rendering index R a ⁇ 90 and at the same time a long life (at least 1000 h).
- the discharge vessel contains an ionizable filling, consisting of at least one inert gas, mercury, at least one halogen and the following elements to form corresponding halides: Tl, Cs, Hf, where the Hf can be replaced in whole or in part by Zr and the two or one of the two rare Earth metals (SE) Dy and / or Gd. I and / or Br are preferably used as halogens for the formation of the halides.
- the inert gas for example Ar with a typical filling pressure in the order of up to approx. 40 kPa, serves to ignite the discharge.
- the desired operating voltage is set by Hg and is typically in the range between approx. 4 mg and 25 mg per cm3 of vessel volume for operating voltages between 120 V and 95 V.
- the filling according to the invention is distinguished from that in EP-A 0 391 283 by the absence of Tm, with essentially equally good color rendering (R a ⁇ 90) and a service life of approx. 1500 h and more. In comparison to EP-A 0 492 205, this corresponds at least to a doubling of the service life with luminous efficacies of approximately 80 lm / W. This is achieved by a targeted increase in the Hf (or Zr) portion. In this way, premature devitrification can be avoided and consequently an extension of the service life can be achieved. An improvement in color rendering is also achieved.
- the molar ratio between the filling proportion of Hf and Zr on the one hand and the filling proportion of Dy and the sum of the filling proportions of SE Dy and Gd on the other hand is at least 0.35.
- the molar ratio is preferably in the range between 0.5 and 1.5.
- the following molar ratios have proven themselves with regard to the other filling components Tl and Cs: Hf (or Zr): Tl at least 0.65, for high wall loads the ratio is preferably in the range between 1 and 2.5, Hf (or Zr): Cs at least 0.35, for high wall loads the ratio is preferably in the range between 0.5 and 1.
- the molar ratio between the filling proportion of Hf or Zr on the one hand and the sum of the filling proportions of the SE (ie Dy and / or Gd) and Tl and Cs, on the other hand, is at least 0.14; for high wall loads, the ratio is preferably in the range between 0.2 and 0.5.
- the molar filling quantity of Hf or Zr is in the range between 0.005 ⁇ mol and 35 ⁇ mol, preferably in the range between 0.05 ⁇ mol and 5 ⁇ mol per cm3 of the volume of the discharge vessel.
- the filling quantities of Cs, Tl, Dy and possibly Gd are up to 30 ⁇ mol, up to 15 ⁇ mol, up to 30 ⁇ mol or up to 0.6 ⁇ mol per cm3 of the vessel volume.
- the discharge vessel is preferably operated within an outer bulb which is evacuated for particularly good color rendering.
- the outer bulb contains a gas filling, for example up to 70 kPa nitrogen (N2) or up to 40 kPa carbon dioxide (CO2), although the color rendering is somewhat reduced.
- the filling contains 23 mg Hg and 14 kPa Ar as the base gas.
- the discharge vessel 2 contains the metal halides listed in Table 1a below.
- the resulting molar ratios between Hf and Zr on the one hand and Cs, Tl, Dy and the sum of the proportions of Cs, Tl and Dy on the other hand are given in Table 1b.
- the specific arc power and the operating voltage are 15 W per mm arc length or 105 V.
- Table 1c shows the lighting values achieved.
- FIG. 2 An embodiment of a 400 W lamp is shown schematically in Figure 2.
- the discharge vessel 2 is squeezed on two sides and is enclosed by a cylindrical, evacuated outer bulb 3 made of tempered glass, which has a base on one side.
- One end of the outer bulb 3 has a rounded tip 17, whereas the other end has a screw base 12.

- the other lead wire is led to the power supply 9 remote from the base via a solid metal support wire which extends along the discharge vessel 2.
- It also has a guide element at the end 15 of the discharge vessel near the base (in the form of a stamped sheet) and a support in the vicinity of the tip 17 in the form of a pitch circle.
- the ends 15, 16 of the discharge vessel 2 are provided with a heat-reflecting coating.
- the filling contains 60 mg Hg and 8 kPa Ar as the base gas.
- the discharge vessel 2 contains the metal halides listed in Table 2a below.
- the resulting respective molar ratios between Hf on the one hand and Cs, Tl, Dy and the sum of the proportions of Cs, Tl and Dy on the other are given in Table 2b.
