Description

Technisches GebietTechnical area

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 and associated lamp for a high-pressure discharge lamp according to the preamble of claim 1. It is in particular fillings for lamps with warm white or neutral white light color. The invention also relates to an associated lamp filled with it.

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, metal halide discharge lamps usually contain sodium. For example, US-A-3,575,630 describes a lamp containing a metal halide fill with elements Na, Tl, and Zr and having a warm white light color. Another example is the lamp described in EP-A 883,160. 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 discharge vessel made of glass and a sodium-containing filling are known to have the disadvantage of sodium diffusion through the discharge vessel, which reduces the lamp life. The sodium diffusion must be reduced with additional measures, for example shielding the power supply in the vicinity of the discharge vessel, which increases the manufacturing cost of the lamp. Another disadvantage of sodium-containing metal halide discharge lamps is their relatively low color rendering. For example, a Na-Sc-containing metal halide discharge lamp of neutral white light color has about typical values for the general color rendering index Ra = 70 and specific 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 for obtaining warm white and neutral white light colors. By substitution of sodium omitted in the lamps filled with it the additional measures to reduce sodium diffusion. Furthermore, the lamps with the Mn-containing filling achieve high values for color rendering with Ra> 95. However, the light output and lamp power is relatively low. For example, on a 250 W reactor, which is also used for high-pressure Na steam lamps, the lamp output is typically 240W.

GB 1235299 offenbart eine Bogenentladungslampe mit V-Halogenid.GB 1235299 discloses a V-halide arc discharge lamp.

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, from DE-A 35 12 757 a filling for metal halide lamps is known 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 oxychloride μ / o 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 and halogen incandescent lamps, which are Planckian emitters, works without problems. However, if one operates metal halide discharge lamps with reduced lamp power (see the o.e. EP 883 160), so their color location removed from the Planckian curve. The lamps lose their white light color and the color rendering deteriorates.

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.Figure 1 (prior art) shows a color locus of a metal halide lamp capped bilaterally with a power of 250 W and a neutral white fill (HQI-TS 250W / NDL from OSRAM), having a Na-containing metal halide fill. The power of the lamp was reduced on an electronic ballast up to its half luminous flux in steps of about 250W to 160W. With decreasing power, the color location of the lamp moves out of the area of Judd's straight line. The lamp is thus 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 with it can be dimmed very well, because the color locus migration takes place with decreasing power approximately parallel to the Planckian curve, and nevertheless a high color rendering is maintained.

Bevorzugte Ausführung der ErfindungPreferred embodiment of the invention

Ein Ausführungsbeispiel einer 250 W Metallhalogenidlampe 1 ist in Fig. 2 schematisch dargestellt. Sie umfasst ein zweiseitig gequetschtes Entladungsgefäß 2 aus Quarzglas, das von einem zylindrischen evakuierten Außenkolben 3 aus Hartglas umschlossen ist, der einseitig gesockelt ist. Das eine Ende des Außenkolbens 3 besitzt eine abgerundete Kuppe 17, wohingegen das andere Ende einen Schraubsockel 12 aufweist. Ein Haltegestell 6 fixiert das Entladungsgefäß 2 axial im Innern des Außenkolbens 3. Das Haltegestell 6 besteht aus zwei Zuleitungsdrähten, von denen der eine mit der sockelnahen Stromzuführung 8 des Entladungsgefäßes 2 verbunden ist. Der andere Zuleitungsdraht ist über einen massiven Metallstützdraht, der sich entlang des Entladungsgefäßes 2 erstreckt, zur sockelfernen Stromzuführung 9 geführt. Er besitzt außerdem ein Führungselement 15 am sockelnahen Ende (in Form eines Stanzbleches) und eine Abstützung 13 in der Nähe der Kuppe 17 in Form eines Teilkreises. Die Enden 4,5 des Entladungsgefäßes 2 sind mit einem wärmereflektierenden Belag 16 versehen. Am Haltegestell 6 ist zusätzlich ein auf einem Metallplättchen aufgebrachtes Gettermaterial 14 angeschweißt. Das Volumen des Entladungsgefäßes 2 beträgt ca. 5,2 ml. Der Abstand der Elektroden 11 beträgt 27,5 mm. Als Grundgas befinden sich im Entladungsgefäß 56 mbar Ar. Zur Erniedrigung der Durchschlagsspannung kann als Grundgas alternativ ein Penninggemisch mit Ne:Ar = 99:1 verwendet werden.An embodiment of a 250 W metal halide lamp 1 is shown schematically in FIG.
