Definitions
- the invention relates to a high-pressure discharge lamp according to the preamble of claim 1. These lamps are intended for general lighting.
- the object of the present invention is to provide a high-pressure discharge lamp with metal halide filling, which is suitable for general lighting, wherein it is well heat-ignitable.
- Previous metal halide lamps are only capable of high thermal ignition typ. ⁇ 10-15kVpk.
- Keramsiche lamps were ignited with high ignition voltage by means of hot igniters.
- Socket mount systems are to be dimensioned according to the required insulation lengths.
- the use of metal halide fillings in ceramic metal halide lamps with elemental metallic additives such that the Hg dose a value of typ. 50 mg / cem significantly, preferably by means of a dose ⁇ 10 - 1 mg / cem, below.
- Suitable metal additions besides Hg are metals which form readily volatile metal halides with J, Br, Cl, which are also filled as metal halide in the lamp, e.g. In, Zn, Mg, Mn, Al, Tl, Sc continue. Typical dose is 0.1-15mg / cc.
- MH additives of Li, Na, Ca can be used.
- MH can be enriched by Hg halides (e.g., Hgl2, HgBr2, HgC12) so that burning voltage can be set in a wider range.
- Hg halides e.g., Hgl2, HgBr2, HgC12
- the starting gas pressure (typically Ar noble gases or their mixture) of the lamps is 15-1000 mbar.
- the lamps show a rapid drop in the hot restrike voltage and can be hot re-ignited by external ignition aids with the help of increased resonance ignition voltages ⁇ 6kVpk.
- the invention relates to small and medium power ceramic metal halide lamps up to about 250 W with good hot-ignitability.
- the lamp contains filling components which have particularly good hot-ignitability, ie their ignition voltage is significantly reduced after switching off the lamp.
- metal halide fillings in ceramic discharge vessels with elemental metallic additives such that the Hg dose falls below a value of typ. ⁇ 50 mg / ccm preferably about ⁇ 10 - 1 mg / ccm. He should best sign 1 mg / cm 3 .
- the metal halide filling can be enriched in particular by Hg halides HgX2 (eg HgI2, HgBr2, HgC12) in such a way that the burning voltage can be adjusted within a relatively wide range.
- Hg halides HgX2 eg HgI2, HgBr2, HgC12
- the starting gas pressure (typically Ar, noble noble gases or their mixture) of the lamps is 15-1000 mbar cold.
- Typical dose of elemental metal component is 0.1- 15 mg / ccm depending on the metal type.
- metal halides of Li, Na, Ca may be used singly or in mixture as additives.
- the starting gas pressure (typically Ar, noble gases or their mixture) of the lamps is in particular 25-1000 mbar.
- Hot re-ignitable ceramic discharge vessel with a structural contour Hot re-ignitable ceramic discharge vessel with a structural contour:
- the lamp construction can include conductive ignition aids in the outer bulb (eg capacitive, sintered-on or via press-fitted conductor guides, which generate a capacitive coupling of the electrode potentials on the outer wall of the discharge vessel and thereby generate excessive field strengths in the regions of the electrode tips or along the electrode bushing .).
- conductive ignition aids in the outer bulb eg capacitive, sintered-on or via press-fitted conductor guides, which generate a capacitive coupling of the electrode potentials on the outer wall of the discharge vessel and thereby generate excessive field strengths in the regions of the electrode tips or along the electrode bushing .
- 1 shows a high-pressure discharge lamp with discharge vessel.
- Figure 2-5 further exemplary embodiments.
- FIGS. 1 a and 1 b each schematically show a discharge lamp 1. It is essentially a ceramic lamp.
- the discharge vessel 2 of A12O3 ceramic has a given inner diameter ID, for example, 2 to 5 mm inner diameter ID, and a given inner length IL, for example 10 to 15 mm inner length IL.
- the filling contains, for example, NaI, NaBr, InBr, InJ, CeJ3, CeBr3, Xe, HgJ2 and Hg.
- the discharge vessel contains two electrodes facing each other.
- the discharge vessel is elongated (Figure Ia) with rounded ends or bulbous ( Figure Ib).
- the lamp has an outer bulb and a ceramic base.
- Figure 2 shows an elongate, rounded discharge vessel 2 in detail with dimensions.
- Tab. 2a shows several fillings for discharge vessel according to FIG. 2.
- Tab. 2b shows fillings for discharge vessels with bulbous form. from. 3 shows the composition of a melt for Tab. 2a.
- Tab. 4 shows fillings for elliptical discharge vessels.
- Table 5 shows the melt compositions for the fillings from Tab. 4
- FIG. 3 shows illustrations of a further exemplary embodiment of a lamp in two views rotated through 90 ° (FIGS. 3 and 3 b).
- FIG. 4 shows a lamp with an elongate rounded discharge vessel in an evacuated outer bulb.
- Figure 5 shows two rotated by 90 ° side views of a lamp with Zundst Shape 20 made of Pt, which is guided along the outside of the discharge vessel. It is parallel to the axis and extends from the first end 21 via the discharge volume 22 to the second end 23. Capillaries 24 are still attached to the end.
