Description

Technisches GebietTechnical field

Die Erfindung geht aus von einer Metallhalogenidfüllung und zugehörige Lampe für eine Hochdruckentladungslampe gemäß dem Oberbegriff des Anspruchs 1. Es handelt sich dabei insbesondere um Füllungen für Lampen mit warmweißer oder neutralweißer Lichtfarbe. Die Erfindung betrifft zudem eine zugehörige damit befüllte Lampe.The invention relates to a metal halide fill and associated lamp for a high-pressure discharge lamp according to the preamble of claim 1. It these are in particular fillings for lamps with warm white or neutral white light color. The invention also relates to an associated filled therewith Lamp.

Stand der TechnikState of the art

Zur Erzielung warmweißer und neutralweißer Lichtfarben enthalten Metallhalogenidentladungslampen meist Natrium. Zum Beispiel beschreibt die US-A 3 575 630 eine Lampe, die eine Metallhalogenidfüllung mit den Elementen Na, Tl, und Zr enthält und eine warmweiße Lichtfarbe hat. Ein weiteres Beispiel ist die in EP-A 883 160 beschriebene Lampe. Sie besitzt eine Metallhalogenidfüllung mit den Elementen Na, Sc, und anderen Bestandteilen wie Mn. Diese Lampe ist dimmbar.To achieve warm white and neutral white light colors contain metal halide discharge lamps mostly sodium. For example, US-A 3,575,630 describes a lamp containing a metal halide filling with the elements Na, Tl, and Zr and has a warm white light color. Another example is that in EP-A 883 160 lamp described. It has a metal halide filling with the elements Na, Sc, and other ingredients like Mn. This lamp is dimmable.

Metallhalogenentladungslampen mit einem Entladungsgefäß aus Glas und einer natriumhaltigen Füllung haben bekanntlich den Nachteil der Natriumdiffusion durch das Entladungsgefäß, was die Lampenlebensdauer reduziert. Die Natriumdiffusion muss mit zusätzlichen Maßnahmen, zum Beispiel Abschirmung der Stromzuführung in Nähe Entladungsgefäß, reduziert werden, was die Herstellungskosten der Lampe erhöht. Ein weiterer Nachteil natriumhaltiger Metallhalogenidentladungslampen ist ihre relativ niedrige Farbwiedergabe. Eine Na-Sc-haltige Metallhalogenidentladungslampe neutralweißer Lichtfarbe hat zum Beispiel etwa typische Werte für den allgemeinen Farbwiedergabeindex Ra=70 und speziellen Farbwiedergabeindex R9=0.Metal halide discharge lamps with a glass discharge vessel and one Sodium-containing fillings are known to have the disadvantage of sodium diffusion the discharge vessel, which reduces the lamp life. The sodium diffusion must take additional measures, such as shielding the power supply in the vicinity of the discharge vessel, reducing the manufacturing cost of the lamp elevated. Another disadvantage of sodium-containing metal halide discharge lamps is their relatively low color rendering. A metal halide discharge lamp containing Na-Sc For example, neutral white light color has typical values for the general Color rendering index Ra = 70 and special color rendering index R9 = 0.

Die DE-A 199 07 301 beschreibt eine Metallhalogenidfüllung mit Mn ohne Na für Metallhalogenidentladungslampen zur Erzielung von warmweißer und neutralweißer Lichtfarben. Durch Substitution von Natrium entfallen in den damit gefüllten Lampen die zusätzlichen Maßnahmen zur Reduzierung der Natriumdiffusion. Weiterhin erzielen die Lampen mit der Mn-haltigen Füllung hohe Werte für die Farbwiedergabe mit Ra>95. Jedoch ist die Lichtausbeute und Lampenleistung relativ gering. So beträgt an einer 250 W-Drossel, die auch für Na-Hochdruckdampflampen verwendet wird, die Lampenleistung typisch 240W.DE-A 199 07 301 describes a metal halide filling with Mn without Na for Metal halide discharge lamps to achieve warm white and neutral white Light colors. Substitution of sodium does not apply in the lamps filled with it the additional measures to reduce sodium diffusion. Farther the lamps with the Mn-containing filling achieve high values for the Color rendering with Ra> 95. However, the light output and lamp wattage relatively low. So on a 250 W choke, that is also for Na high pressure steam lamps the lamp power is typically 240W.

Schließlich ist aus DE-A 35 12 757 eine Füllung für Metallhalogenidlampen bekannt, die ein Metallsilizid wie V5Si3 enthält. Daneben enthält die Füllung Seltenerd- oder Sc-Halogenid und das entsprechende Seltenerdoxihalogenid u/o Sc-Oxid. Das Silizid wirk hier als Halogengetter.Finally, a filling for metal halide lamps is known from DE-A 35 12 757 which contains a metal silicide such as V 5 Si 3 . In addition, the filling contains rare earth or Sc halide and the corresponding rare earth oxyhalide and / or Sc oxide. The silicide acts here as a halogen getter.

Bekanntlich funktioniert das Dimmen von Glühlampen und Halogenglühlampen, die Planck'sche Strahler sind, ohne Probleme. Betreibt man jedoch Metallhalogenidentladungslampen mit reduzierter Lampenleistung (siehe die o.e. EP 883 160), so entfernt sich ihr Farbort vom Planckschen Kurvenzug. Die Lampen verlieren ihre weiße Lichtfarbe und die Farbwiedergabe verschlechtert sich.As is known, the dimming of incandescent lamps and halogen lamps works Planck radiators are without problems. However, one operates metal halide discharge lamps with reduced lamp power (see EP 883 160 above), so removed their color locus from the Planck curve. The lamps lose their white Light color and color rendering deteriorate.

Fig. 1 (Stand der Technik) zeigt ein Farbortdiagramm einer Metallhalogenidlampe, die zweiseitig gesockelt ist mit einer Leistung von 250 W und einer neutralweißen Füllung (HQI-TS 250W/NDL von OSRAM) als Beispiel, die eine Na-haltige Metallhalogenidfüllung besitzt. Die Leistung der Lampe wurde an einem elektronischen Vorschaltgerät bis zu ihrem halben Lichtstrom in Stufen etwa von250W bis 160W reduziert. Mit abnehmender Leistung wandert der Farbort der Lampe aus dem Bereich der Judd'schen Geraden heraus. Die Lampe wird dadurch zunehmend grünstichig.1 (prior art) shows a color locus diagram of a metal halide lamp, which is based on two sides with a power of 250 W and a neutral white Filling (HQI-TS 250W / NDL from OSRAM) as an example, which contains a Na-containing metal halide filling has. The performance of the lamp was measured on an electronic ballast reduced to half their luminous flux in steps of approximately 250W to 160W. As the power decreases, the color locus of the lamp moves out of range the straight line of Judd. The lamp becomes increasingly greenish.

Ein weiterer vorteilhafter Aspekt der Erfindung ist, dass die damit befüllte Metallhalogenidentladungslampe sehr gut dimmbar ist, weil die Farbortwanderung mit abnehmender Leistung etwa parallel zum Planckschen Kurvenzug erfolgt und dabei trotzdem eine hohe Farbwiedergabe erhalten bleibt.Another advantageous aspect of the invention is that the metal halide discharge lamp filled therewith is very well dimmable because the color locus changes with decreasing Performance takes place approximately parallel to the Planck curve and thereby high color rendering is retained.
