Definitions
- the present invention relates to an electrode system for a ceramic discharge lamp Discharge vessel comprising an electrode, a power supply line and a through the ceramic discharge tube led current passage, the platinum group metal or rhenium has a method for producing an electrode system in which a current feedthrough platinum group metal or rhenium-based flush with a metallic solder is soldered into the ceramic component, a preferred ceramic discharge vessel and the use of the electrode system or the preferred discharge vessel in metal halide lamps.
- an electrode system for a metal halide lamp comprising a ceramic discharge vessel, an electrically conductive bushing and a Electrode.
- the construction is designed for high operating temperatures.
- the light output is a lamp limited by its dimension.
- the object of the present invention is, on the one hand, the light output of To increase lamps and on the other hand to allow a smaller sizing.
- the object is achieved in that the current feedthrough through the ceramic discharge vessel Rhenium or platinum group metal metals, in particular of rhenium or a platinum group metal or a rhenium or platinum group metal alloy.
- a use according to the invention for metal halide lamps with increased luminous efficacy allows. Smaller lamps with improved light output are with the electrode system produced.
- the electrode system according to the invention stops in the area of the current feedthrough Temperatures up to 2000 ° C stood. Thus, also an improved color reproduction reachable.
- the inventive technique enables the manufacture of lamps increased radiation power, improved color reproduction and a considerable reduction the dimensions.
- the current feedthrough with a platinum group metal solder in soldered the ceramic discharge vessel.
- the electrode in tungsten the power supply as a base metal pin, Rhenium or platinum group metal as an essential component, as a main component or as a major part of the power supply, the current leadthrough made of rhenium or a rhenium alloy or of a platinum group metal or of a platinum group metal alloy, in particular iridium or iridium alloy, a ceramic discharge vessel made of alumina and a flush soldering of the current feedthrough in the discharge vessel.
- the current feedthrough consists of two joined together Balls of platinum group metal or rhenium, or their alloys, in which the Space between the balls and the discharge vessel with a platinum group metal-based solder is filled.
- the combination of the present invention up to 2000 ° C resistant current implementation and the direct soldering of the current feedthrough with the ceramic burner allows a compact new design of ceramic burner with optimized light output and reduced Metallhalogenidgehalt.
- the discharge vessel to the Shafts shortened, which are usually arranged to receive the current feedthrough.
- a power feed pin may optionally be between the power supply and the power feedthrough be arranged and electrically connect them together.
- the ceramic discharge vessel may be referred to as burner and comprise Al 2 O 3 , sapphire, yttrium aluminum garnet, aluminum nitride, aluminum oxynitride, silicon aluminum oxynitride, in particular consisting of Al 2 O 3 .
- the current feedthrough penetrates the ceramic discharge vessel gas-tight and connects the electrode with the power supply or the power supply pin.
- the solder is soldered flush to the current feedthrough and the discharge vessel.
- a solder of platinum group metal or their alloy is soldered flush to the current feedthrough and the discharge vessel.
- FIG. 1 shows a cross section of an electrode system according to the invention for use in metal halide lamps with a ceramic (Al 2 O 3 ) discharge vessel.
- FIG. 2 shows a cross section of the ceramic discharge vessel with integrated Electrode system.
- Figure 3 shows a comparison cross-section of a discharge vessel.
- This electrode system comprises an electrode 1, as typically in discharge lamps is used, a power supply line 3, which may be formed as a non-noble metal pin and a current feedthrough 2.
- the current feedthrough 2 contains as an essential component Rhenium or platinum group metal and consists of two joined balls.
- the assembled balls 2 fill with a Lot 4, the opening for the current feedthrough in the discharge vessel 5 from.
- the current feedthrough 2 protrudes minimally into the discharge vessel 5, so that the electrode material of the electrode 1 is not in contact with the discharge vessel 5 is coming.
- the interior of the discharge vessel 5 is sealed with the solder.
- the number of balls is arbitrary.
- the power supply line 3 is the electrical connection between the lamp base and the Current feedthrough 2 through the ceramic discharge vessel 5.
- a power supply pin attached.
- this pin exists i.d.R. made of a Nb alloy.
- lying current feedthrough 2 are in addition to Nb alloys and other materials based non-precious metals including refractory metals possible.
- the discharge vessel 5 has no ceramic shaft in the region of the current feedthrough on. Minor gains in this area can be beneficial. (Fig.2).
