Description

Als Tisch- oder Hängeleuchte, insbesondere als Farbprüfgerät ausgebildete Leuchte mit Xenon-Hochdruckentladungslampe Die Erfindung bezieht sich auf eine als Tisch- oder Hängeleuchte, insbesondere als Farbprüfgerät ausgebildete Leuchte mit Xenon-Hochdruckentladungslampe mit Reflektor und im Le.uchtendom angeordnetem Zündgerät, das mittels eines während des Betriebes durch die Wärme. der Xenonlampe erzeugten Luftstromes gekühlt wird Das Zündgerät enthält außer anderen Schaltelementen auch Kondensatoren, die trotz der hohen Betriebstemperatur der Xenonlampe nicht zu stark erhitzt werden dürfen. Bei einer bekannten Leuchte sind in der Reflektorrückwa.nd außermittig Luftdurchgangsöffnungen angeordnet. Das Zündgerät ist mit einem besonderen Gehäuse in dem Dom eingebaut. Die Luftkanäle werden von diesem Gehäuse und den Domwänden gebildet. Durch die außermittige Anordnung der Luftdurchgangsöffnungen wird der der Lampe zugekehrte Boden des Zündgerätegehäuses nur zum Teil von dem Luftstrom bestrichen. Im mittleren Bereich findet keine Luftströmung statt, so daß sich hier Wärmestauungen bilden können.As a table or hanging lamp, especially designed as a color testing device Luminaire with xenon high pressure discharge lamp The invention relates to a Table or hanging lamp, in particular a lamp designed as a color testing device Xenon high-pressure discharge lamp with reflector and ignition device arranged in the lamp dome, that by means of a heat generated during operation. generated by the xenon lamp The ignitor also contains other switching elements Capacitors that are not too strong despite the high operating temperature of the xenon lamp may be heated. In a known light are in the reflector Rückwa.nd eccentrically arranged air passage openings. The ignitor has a special one Housing built into the dome. The air ducts are from this housing and the dome walls educated. Due to the off-center arrangement of the air passage openings, the The base of the ignition device housing facing the lamp is only partially affected by the air flow coated. In the middle area there is no air flow, so that here Can build up heat build-up.

Die Erfindung beseitigt diese Schwierigkeiten. Erfindungsgemäß hat die unter Bildung von radialen Luftführungskanälen im Abstand von dem Domboden angeordnete Reflektorrückwanid in der Mitte eine Luftdurchgangsöffnung, zwischen der und der Lampe eine mit der Reflektorrückwand radiale Luftführungskanäle bildende Kulisse angeordnet ist.The invention overcomes these difficulties. According to the invention has which are arranged at a distance from the dome base, forming radial air ducts Reflector rear wall in the middle an air passage opening between which and which Lamp with the reflector back wall forming radial air ducts backdrop is arranged.

Ein Ausführungsbeispiel der Erfindung ist in der Zeichnung dargestellt.An embodiment of the invention is shown in the drawing.

Das Gehäuse der Leuchte besteht im wesentlichen aus dem Reflektor 1, der die Xenonlampe 2 umgibt, und dem Dom 3, in dem das Zündgerät 4 der Lampe eingebaut ist, das aus elektrischen Gründen nahe der Lampe angeordnet sein muß. Die Reflektorrückwand 5 hat eine Luftöffnung 6, der eine ebene, auf der Lampenseite hell glänzende Aluminiumscheibe 7 vorgelagert ist. Die Rückwand 5 bildet sowohl mit der Scheibe 7 als auch mit dem Boden 8 des Domes 3 Luftkanäle 9 und 10. Der Reflektorraum ist nach außen durch eine mattiertes Spezialglas 11 bis auf die Luftöffnung 12 an der Reflektorwand abgeschlossen.The housing of the lamp essentially consists of the reflector 1, which surrounds the xenon lamp 2, and the dome 3, in which the igniter 4 of the lamp is built in, which must be arranged near the lamp for electrical reasons. The reflector rear wall 5 has an air opening 6, which is a flat one on the lamp side bright shiny aluminum disc 7 is upstream. The rear wall 5 forms both with the disc 7 and with the bottom 8 of the dome 3 air channels 9 and 10. The The reflector space is to the outside through a matted special glass 11 except for the air opening 12 completed on the reflector wall.

Beim Betrieb der Lampe wird die Luft in dem Reflektorraum erwärmt und zieht durch die Luftkanäle 9 und 10 nach oben ab, wobei der Boden des Domes infolge der erzwungenen Luftführung durch die Kanäle auf seiner ganzen Fläche bestrichen und gekühlt wird. Die nach oben aufsteigende Warmluft saugt dabei durch die Öffnungen 12 zwischen Abschlußglas und Reflektor kalte Außenluft nach.When the lamp is operated, the air in the reflector space is heated and pulls through the air channels 9 and 10 upwards, the bottom of the dome as a result of the forced air flow through the ducts coated over its entire surface and is cooled. The rising warm air sucks through the openings 12 cold outside air between the cover glass and reflector.

Die Erfindung bietet folgende Vorteile: Da sowohl zwischen Kulisse und Refiektorrückwand als auch zwischen Reflektorrückwand und Domboden radiale Luftführungskanäle vorhanden sind, die durch die zentrale Öffnung in der Reflektorrückwand miteinander verbunden sind, ist einerseits vermieden, daß die an der Lampe vorbeistreichende erwärmte Luft unmittelbar zu dem Domboden strömt, und andererseits erreicht, daß unter Vermeidung jeglicher Wärmestauung die ganze Fläche des Dombodens vom Kühlluftstrom bestrichen wird. Weiterhin ist ein besonderes Gehäuse für das Zündgerät eingespart.The invention offers the following advantages: Since both between backdrop and reflector rear wall as well as radial air ducts between the reflector rear wall and the dome base are present, which through the central opening in the reflector back wall with each other are connected, is on the one hand avoided that the past the lamp heated air flows directly to the dome floor, and on the other hand achieves that while avoiding any accumulation of heat, the entire area of the dome floor from the cooling air flow is coated. Furthermore, a special housing for the ignition device is saved.
