Definitions
- the invention relates to a high-pressure discharge lamp according to the preamble of claim 1.
- Such lamps are in particular high-pressure discharge lamps with ceramic discharge vessel or quartz glass vessel for general lighting.
- WO 98/25294 discloses a high-pressure discharge lamp in which a metal halide filling is used together with a ceramic discharge vessel.
- the filling also includes Hg and inert gas with a cold filling pressure of typically 250 mbar.
- Phase control is known, for example, from DE102005009940.
- the object of the present invention is to provide a high-pressure discharge lamp with metal halide filling and Hg and noble gas, in which simple means of operation on a designed for higher power ballast is possible.
- the cause of restarting peak during the reinsertion of current flow is connected to the cooling Verrin ⁇ delay the electrical conductivity.
- the reduction is particularly pronounced because metal halide fillings contain free halogens. Due to their high electronegativity, these are particularly electron-consuming, especially iodine and bromine.
- the invention proposes to use a noble gas under high pressure as a buffer gas.
- the pressure should be between 4 and 8 bar.
- a cold filling pressure between 5 and 7 bar, wherein Argon, krypton and neon and mixtures thereof are suitable as inert gas above all.
- a typical content of Hg is 25 to 200 ⁇ mol / cm 3 , corresponding to 5 to 40 mg / cm 3 Hg.
- the function of the inert gas is not here to provide instant light, as has long been known for xenon under high pressure, but the absolute heat capacity to increase significantly the plasma and thereby equal ⁇ time to increase the thermal conductivity only to a small extent.
- metal halide lamps which are used as a retrofit solution for conventional high-pressure mercury lamps used, for example, in street lighting.
- the novel lamps have a much better color reproduction compared to mercury and sodium high-pressure lamps and, moreover, a higher efficiency.
- the discharge vessel is preferably made of aluminum-containing ceramic such as PCA or YAG, AlN, or A1YO3. But it can also consist of quartz glass. Both are known per se from the prior art. The choice of filling metals is not subject to any particular restrictions. -A-
- Typical metals are rare earth metals, Na and thallium.
- the newly proposed concept is also suitable for mixing ⁇ light lamps with a discharge vessel having a Metallha- logenid Stung.
- a filament is used as a dropping resistor instead of a choke.
- the power reduction is preferably selected in the range 95 to 55%.
- a phase control is used as power blanking before ⁇ Trains t used, but other concepts are not excluded.
- the voltage regimenge ⁇ set is a common alternating voltage, ty ⁇ pisch are sine and square wave voltages. The concept is also suitable for protection against short-term grid interruptions that can occur in less developed countries.
- the concept according to the invention is particularly suitable for lamps of low power in the range of 15 to 400 W.
- Fig. 2 is a diagram showing the principle of phase-section control
- FIG. 3 is a diagram showing the re-ignition peak as a function of the duration of the phase-section control
- FIG. Fig. 4 is a graph showing the re-ignition voltage as a function of the blanking time for various lamp types (4a) and (4b).
- FIG. 1 shows schematically a metal halide lamp 1. It consists of a discharge vessel 2 made of ceramic, in which two electrodes are inserted (not visible). The
- Discharge vessel has a central part 5 and two ends
- Capillaries are executed.
- the discharge vessel and the seals are integrally made of a material such as PCA.
- the discharge vessel 2 is surrounded by an outer bulb ⁇ ben. 7
- the discharge vessel 2 is in the outer bulb by means of ei ⁇ nes frame which includes a short and a long power supply 11 a and IIb supported.
- the discharge vessel contains a filling which is typically Hg
- iodides (15 mg / cm 3 ) and 5 to 30 mg / cm 3 of iodides of metals.
- the iodides can partially or completely through
- a typical filling comprises Na, Dy, Tm, Ce and thallium as metals.
- As a noble gas is
- Figure 2 shows schematically a sine AC power source (curve d) imprinted with a phase control between 50 and 100% as a function of time t (in ms).
- Curve c stands for 95%, curve b for 55% and curve a for 50%.
- the apex of the current I (in amps) grows there in ⁇ with increasing duration of the phase section and is most largest at curve a, so that no loss in the luminous flux has to be accepted.
- FIG. 3 shows, by way of example for the ratios of FIG. 2, the influence of the duration of the zero-current phase on the re-ignition behavior of the burning voltage U (in volts) of a conventional lamp without high inert gas pressure.
- the voltage curve shows no feature in the absence of (curve d) or low zero-current phase (curve c).
- curve d the absence of
- curve c low zero-current phase
- increas ⁇ mender zero current phase is in the range of about 0 to 50% of the total phase period, assumes the Wiederzündspit- ze U max significantly (curve b and a).
- Figure 4 shows the increase of the re-ignition voltage (in V) as a function of the blanking time (in ms) for different lamp types.
- the behavior in a conventional filling of a metal halide lamp MH (70 W power) with low inert gas pressure (250 mbar) is shown in FIG. 4 a (curve MH).
- the restarting peak ⁇ be already achieved after just 2 ms the critical value of 330 V, which is the threshold for the re-ignition at mains voltage.
- FIG. 4a also shows the conditions for a typical high- pressure sodium lamp (curve NAH), which does not know the problem due to a lack of halogen-containing filling. There he is ⁇ maintenance according to virtually determine no increase in relight ⁇ tension. In a filling according to the invention (curve MH 35 watts, 6 bar argon) in Figure 4b) this critical value is not reached even after 5 ms, in contrast to a filling with 2 bar noble gas pressure curve MH 35 watts 2 bar argon) ,
- the time window of 5 ms in this specific embodiment is the maximum value of a zero-current phase, which can occur with a blanking down to a maximum of 55%. Despite maximum blanking, a reliable re-ignition is ensured in the next phase.
