Definitions

the invention relates to a high-pressure discharge lamp according to the preamble of claim 1.
Fully electronic circuits are increasingly used as ballasts for such high-pressure discharge lamps with metal halide fillings, which supply the lamps with a rectangular current. This enables flicker-free operation of the high-pressure discharge lamps.
such an electronic ballast has a much lower weight than a conventional ballast with choke.
the metal halide high-pressure discharge lamps with a low-frequency square-wave current results in sound emissions in the listening area, which can reach levels above 40 dBA.
the sound waves are generated by resonances in the usually cylindrical, spherical or ellipsoidal interior of the discharge vessel, which arise when the harmonics of the rectangular current interact with the plasma in the discharge vessel.
the object of the invention is to reduce these disturbing sound emissions by means of constructional measures in order to ensure universal use of such lamps.
the diameter of the interior in the area of the circular cylinder must be such that the inner wall is at approximately 950 ° C. when the lamp is in operation. If the diameter is larger, the color temperature increases; if the diameter is smaller, so there is premature devitrification and the metal halide high-pressure discharge lamp fails. Approximately the arc length can be assumed as a guideline for the length of the circular cylindrical middle part.
the interior of the discharge vessel 2 has a circular-cylindrical central region 11 and - toward the shafts 3, 4 - each has a transition region 12, 13, which has the shape of a circular cone.
the internal dimensions of the discharge vessel for a 2500 W and a 4000 W metal halide high-pressure discharge lamp, as shown in FIG. 1, are summarized in the following table: Power consumption of the lamp 2500 W. 4000 W Length l 1 of the cylindrical central region 11 18 mm 35.5 mm Length l2 of the conical transition regions 12, 13 12 mm 15 mm Inner diameter d 1 of the cylindrical central region 11 27 mm 28 mm Transition angle ⁇ from the cylindrical central region 11 to respective conical transition region 12, 13 145 ° 145 ° Electrode gap 14 mm 34 mm Total length of the lamp 355 mm 405 mm
