Abstract

The tungsten-halogen lamp holder (3) of the lighting fixture is retained by a mount consisting of two U-profiled parts (6, 7) at a distance behind the reflector shell (1) that can be chosen by displacing the second U-profiled part (7). The reflector shell (1) has an opening (2) through which the tungsten-halogen lamp (4) projects into the reflector chamber (20). The cross-section of the opening (2) is a multiple of the cross-section of the tungsten-halogen lamp, so that a wide annular gap (21) for through-ventilation is free between the tungsten-halogen lamp (4) and the opening rim (9) of the reflector shell (1). In order to form a through-ventilation chamber (22), the mount (6, 7) is completely open to the rear and, moreover, on two opposite sides. The tungsten-halogen lamp holder (3) is freely retained by the mount (6, 7) in the through-ventilation chamber (22) adjoining the annular gap (21), so that the holder (3) is enveloped by the air current flowing through the annular gap (21), and the cap (base) of the tungsten-halogen lamp is cooled. The service life of the tungsten-halogen lighting fixture is thereby substantially increased. <IMAGE>

Description

Die Erfindung betrifft eine Leuchte gemäss dem Oberbegriff des Patent­anspruchs 1, insbesondere eine Halogenleuchte.The invention relates to a lamp according to the preamble of claim 1, in particular a halogen lamp.

Bei den aus der Praxis bekannten Halogenleuchten dieser Art ist eine massive Halterung für die Glühbirnenfassung und die in einem Abstand vor ihr angeordnete Reflektorschale vorgesehen. Der Durchmesser der Oeffnung der Reflektorschale ist um eine kleine Toleranz grösser als der Durchmesser der zylindrischen Halogenglühbirne, damit diese gerade noch durch die Oeffnung hindurchgesteckt bzw. die Reflektorschale über die Glühbirne geschoben und auf der Halterung festgeschraubt werden kann und möglichst die gesamte Strahlung der Glühbirne von der Reflek­torschale nach vorne reflektiert wird und keine Hitze (Wärmestrahlung, erhitzte Luft) von der Glühbirne nach hinten gelangt.In the halogen lamps of this type known from practice, a massive holder for the bulb holder and the reflector shell arranged at a distance in front of it are provided. The diameter of the opening of the reflector shell is a small tolerance larger than the diameter of the cylindrical halogen light bulb, so that it can just be pushed through the opening or the reflector shell can be pushed over the light bulb and screwed onto the holder and, if possible, the entire radiation of the light bulb from the reflector shell is reflected to the front and no heat (heat radiation, heated air) gets back from the light bulb.

Bei einer aus der DE-A-37 10 147 bekannten Leuchte befindet sich in einem zylindrischen, von einem kegelförmigen Dachteil verschlossenen Gehäuse ein Fassungsträger in Form eines nach unten offenen Topfes, an dessen Topfboden die Glühbirnenfassung (der Glühbirnensockel) befes­tigt ist. Der Fassungsträger ist mittels eines Gewinderinges axial verschiebbar im Gehäuse gelagert. Ein Glasreflektor ist mittels Schrauben und Montagefedern am kegelförmigen Dachteil gehalten. Die Reflektorschale hat eine Oeffnung, deren Durchmesser um eine kleine Toleranz grösser ist als der Durchmesser des Kopfs der Glühbirne, so dass der Glühbirnenkopf mit Hilfe des axial verschiebbaren Fasssungs­trägers gerade durch die Oeffnung hindurch bewegbar ist.In a luminaire known from DE-A-37 10 147 there is a holder in the form of a pot which is open at the bottom, in a cylindrical housing closed by a conical roof part, to the bottom of which the bulb socket (the bulb socket) is attached. The frame carrier is axially displaceably mounted in the housing by means of a threaded ring. A glass reflector is held on the conical roof part by means of screws and mounting springs. The reflector shell has an opening, the diameter of which is a small tolerance larger than the diameter of the head of the light bulb, so that the light bulb head can be moved straight through the opening with the aid of the axially displaceable holder.

Ohne Reflektor ausgeführte Leuchten anderer Art sind ferner aus der US-A-3 694 649, US-A-1 825 641 und FR-A-1 021 604 bekannt.Luminaires of other types without a reflector are also known from US-A-3,694,649, US-A-1,825,641 and FR-A-1,021,604.

Die bisherigen Halogenleuchten, die üblicherweise mit einer Spannung von 12 Volt und 50 bis 75 Watt Leistung betrieben werden, haben Le­bensdauern, die bei weitem nicht der Lebensdauer entsprechen, die man von Halogenleuchten eigentlich erwarten könnte.The previous halogen lights, which are usually operated with a voltage of 12 volts and 50 to 75 watts of power, have lifetimes that are far from the lifespan that you could actually expect from halogen lights.

Der Erfindung liegt die Aufgabe zugrunde, die Lebensdauer der Leuchten zu verlängern.The invention has for its object to extend the life of the lights.

Die erfindungsgemässe Lösung der Aufgabe ist Gegenstand des Patentan­spruchs 1. Sie geht von der Erkenntnis aus, dass die verminderte Le­bensdauer durch einen im Bereich der Fassung der Halogenbirne (am Ha­logenbirnensockel bzw. -fuss) auftretenden Wärmestau bedingt ist.The solution to the problem according to the invention is the subject of claim 1. It is based on the knowledge that the reduced service life is caused by a heat build-up occurring in the area of the halogen bulb socket (on the halogen bulb base or base).

Ausgehend von dieser Erkenntnis lehrt die Erfindung, den Querschnitt der Oeffnung der Reflektorschale auf ein Mehrfaches des Glühbirnen­querschnitts zu vergrössern, so dass zwischen der Glühbirne und dem Oeffnungsrand der Reflektorschale ein breiter Ringspalt für einen Luftdurchzug frei wird, die Halterung zur Bildung eines Luftdurchzugs­raums nach hinten und/oder seitlich offen ausführen und die Glühbir­nenfassung durch die Halterung frei im an den Ringspalt anschliessen­den Luftdurchzugsraum zu halten, so dass die Glühbirnenfassung rundum vom durch den Ringspalt strömenden Luftstrom umströmt wird.Based on this knowledge, the invention teaches to increase the cross section of the opening of the reflector shell to a multiple of the light bulb cross-section, so that between the light bulb and the opening edge of the reflector shell a wide annular gap is free for air passage, the bracket for forming an air passage space to the rear and / or run open to the side and keep the bulb holder free in the air passage space adjoining the annular gap by the holder, so that the air stream flowing through the annular gap flows around the bulb holder.

Die Erfindung lehrt mithin das Gegenteil dessen, was man bisher vorge­kehrt hat: Nicht zu verhindern, dass Licht und Wärmestrahlung (sowie erhitzte Luft) von der Glühbirne nach hinten gelangt, sondern - unter Inkaufnahme einer grösseren Licht- und Wärmerückstrahlung - die von der Glühbirne erwärmte Luft als Kühlluft für die Glühbirnenfassung und damit den Glühbirnenfuss zu nutzen, d.h. mit dem Reflektorraum, dem breiten Ringspalt und dem Halterungsraum einen Luftdurchzugsraum zu bilden, durch den die Luft hindurchströmt. Dabei nutzt die Erfindung die Tatsache, dass die von der Glühbirne erhitzte Luft zwar wärmer als die Umgebungsluft aber wesentlich kälter als die für die Lebensdauer der Halogenbirne noch unkritische Temperatur von 120° C ist, und dass die damit erreichte Kühlung der Glühbirnenfassung die infolge der Ver­grösserung der Oeffnung erhöhte Erwärmung der Fassung durch die nach hinten durch die Oeffnung auf die Fassung abgestrahlte Wärmestrahlung der Glühbirne überwiegt.The invention therefore teaches the opposite of what has been done so far: not to prevent light and heat radiation (and heated air) from coming back from the light bulb, but - while accepting a greater amount of light and heat reflection - that the light bulb warms up To use air as cooling air for the bulb holder and thus the bulb base, ie with the reflector space, the wide annular gap and the mounting space to form an air passage space through which the air flows. The invention makes use of the fact that the air heated by the light bulb is warmer than the ambient air but significantly colder than the temperature of 120 ° C., which is still uncritical for the life of the halogen bulb, and that the cooling of the light bulb holder thus achieved is due to the enlargement the opening, increased warming of the socket predominates due to the heat radiation of the light bulb radiated backwards through the opening onto the socket.

Wesentlich ist bei der Erfindung neben dem breiten Ringspalt, dass die Glühbirnenfassung in dem vorzugsweise oben gänzlich offenen und seit­lich auch weitgehend offenen Luftdurchzugsraum frei gehalten ist, so dass sie von der Luft umströmt wird. Wäre die Fassung wie bei der aus der DE-A-37 10 147 bekannten Leuchte am Boden eines topfförmigen Fas­sungsträgers angeordnet, so würde darin ein Wärmestau enstehen und die Fassung bei vergrösserter Reflektorschalenöffnung wegen der erhöhten Wärmerückstrahlung der Glühbirne sogar noch stärker erhitzt als bei den üblichen Halogenleuchten.In addition to the wide annular gap, it is essential in the invention that the light bulb holder is kept free in the air passage space, which is preferably completely open at the top and largely open on the side, so that the air flows around it. If the socket were arranged on the bottom of a pot-shaped holder, as in the lamp known from DE-A-37 10 147, heat would build up in it and the socket would be heated even more than usual with an enlarged reflector shell opening due to the increased heat reflection of the light bulb Halogen lights.

Im folgenden wird ein Ausführungsbeispiel der Erfindung anhand der Zeichnung näher beschrieben. Es zeigen:

  • Fig. 1 eine Seitenansicht einer Leuchte, in Blickrichtung des Pfeils I in Fig. 3,
  • Fig. 2 einen Achsenlängsschnitt durch die Leuchte, entlang der Linie II-II in Figur 3,
  • Fig. 3 einen Achsenquerschnitt durch die Leuchte nach der Linie III-I-­II in Fig. 2, und
  • Fig. 4 einen Achsenquerschnitt durch die Leuchte nach der Linie IV-IV in Fig. 2.
An exemplary embodiment of the invention is described in more detail below with reference to the drawing. Show it:
  • 1 is a side view of a lamp, in the direction of arrow I in Fig. 3,
  • 2 shows an axial longitudinal section through the lamp, along the line II-II in FIG. 3,
  • Fig. 3 shows an axis cross section through the lamp along the line III-I-II in Fig. 2, and
  • 4 shows an axis cross section through the lamp along the line IV-IV in FIG. 2nd

Die Leuchte hat eine halbkugelförmige Reflektorschale 1 aus Metall mit einer durch Abtrennen einer Kugelkappe oder Kalotte erhaltenen, gros­sen Oeffnung 2. Die Reflektorschale 1 und die Fassung 3 einer Halogen­glühbirne 4, deren Stromzuführungsleitungen mit 5 bezeichnet sind, werden von einer aus zwei U-Profilteilen 6, 7 bestehenden Halterung getragen. Der erste U-Profilteil 6 ist an der Rückseite der Reflektor­schale 1 befestigt. Er hat dazu in seinem Steg 8 ein der Oeffnung 2 der Reflektorschale 1 angepasstes Loch und der Oeffnungsrand 9 der Re­flektorschale 1 ist um den Rand des Lochs herumgebördelt. In beiden sich nach hinten erstreckenden Schenkeln 10 des ersten U-Profilteils 6 ist je ein parallel zur Achse 11 der Reflektorschale 1 und den Seiten­rändern der Schenkel 10 verlaufendes Langloch 12 ausgebildet.The lamp has a hemispherical reflector shell 1 made of metal with a large opening 2 obtained by separating a spherical cap or spherical cap. The reflector shell 1 and the socket 3 of a halogen light bulb 4, the power supply lines of which are designated by 5, are made up of one of two U-profile parts 6 , 7 existing bracket worn. The first U-profile part 6 is attached to the back of the reflector shell 1. For this purpose, it has in its web 8 a hole adapted to the opening 2 of the reflector shell 1 and the opening edge 9 of the reflector shell 1 is flanged around the edge of the hole. An elongated hole 12 running parallel to the axis 11 of the reflector shell 1 and the side edges of the legs 10 is formed in each of the two legs 10 of the first U-profile part 6 which extend to the rear.

Auf dem Steg 13 des zweiten U-Profilteils 7 ist an der der Reflektor­schale 1 abgewandten Seite die Glühbirnenfassung 3 befestigt. Der Steg 13 weist im Zentrum eine Durchgangsöffnung 14 für den Halogenbirnen­hals auf, deren Durchmesser entsprechend gross ausgebildet und auf die Grösse der Fassung 3 abgestimmt ist. Die beiden Schenkel 15 des zwei­ten U-Profilteils 7 liegen an den Innenseiten der Schenkel 10 des ers­ten U-Profilteils 6 und weisen je nach aussen ragende, in die Langlö­cher 12 eingreifende Nasen 16 sowie Gewindebohrungen zum Eingriff von Schrauben 17 auf, die durch die Langlöcher 12 hindurchgreifen und den U-Profilteil 7 fest mit den Schenkeln 10 verbinden. Mit den die Monta­ge erleichternden und eine Führung bildenden Nasen 16 und den durch die Langlöcher 12 greifenden Schrauben 17 sind die beiden Schenkel 15 verschiebbar in den beiden Langlöchern 12 gelagert und in der ge­wünschten Lage an den Langlochrändern fixierbar, so dass sich die Ein­führtiefe der Halogenbirne 4 in die Reflektorschale 1 den Erfordernis­sen entsprechend einstellen lässt. Dabei sind die Nasen 16 und Schrau­ben 17 axial hintereinander angeordnet, wodurch eine Parallelführung des zweiten U-Profilteils 7 beim Verschieben entlang den Langlöchern 12 erreicht und sichergestellt wird, dass die Achse der Halogenbirne 4 in der Achse 11 der Reflektorschale 1 bleibt.The bulb socket 3 is fastened on the web 13 of the second U-profile part 7 on the side facing away from the reflector shell 1. The web 13 has a through opening 14 for the halogen bulb neck in the center, the diameter of which is correspondingly large and is matched to the size of the holder 3. The two legs 15 of the second U-profile part 7 lie on the inner sides of the legs 10 of the first U-profile part 6 and, depending on the outside, projecting lugs 16 engaging in the elongated holes 12 and threaded bores for engaging screws 17 through the elongated holes 12 reach through and firmly connect the U-profile part 7 to the legs 10. With the lugs 16, which facilitate assembly and form a guide, and the screws 17 which extend through the elongated holes 12, the two legs 15 are slidably mounted in the two elongated holes 12 and can be fixed in the desired position on the edges of the elongated holes, so that the insertion depth of the halogen bulb 4 can be set in the reflector shell 1 according to requirements. The lugs 16 and screws 17 are arranged axially one behind the other, which results in parallel guidance of the second U-profile part 7 when moving along the elongated holes 12 and it is ensured that the axis of the halogen bulb 4 remains in the axis 11 of the reflector shell 1.

Die Schenkel 10 des ersten U-Profilteils 6 weisen in der Nähe ihrer hinteren Enden je zwei einander gegenüberliegende Aussparungen 18 auf, an denen die durch die beiden U-Profilteile 6, 7 gebildete Halterung der Reflektorschale 1 und Fassung 3 an einer geeigneten Aufhängung aufgehängt werden kann. An den Aussparungen 18 können zum Beispiel Haltefedern angebracht werden, mit denen die Halterung in einem Lam­pengestell oder -gehäuse angeordnet werden kann.The legs 10 of the first U-profile part 6 each have two mutually opposite recesses 18 in the vicinity of their rear ends, on which the bracket of the reflector shell 1 and socket 3 formed by the two U-profile parts 6, 7 are suspended from a suitable suspension can. Retaining springs, for example, can be attached to the cutouts 18, with which the holder can be arranged in a lamp frame or housing.

Die Reflektorschale 1 und die beiden U-Profilteile 6, 7 bestehen vor­zugsweise aus Aluminium. Im in der Zeichnung dargestellten Ausfüh­rungsbeispiel weist die halbkugelförmige Reflektorschale 1 einen Durchmesser von 60 bis 65 mm auf. Davon ist eine Kugelkappe oder Ka­lotte in einer Höhe von 2 bis 4 mm abgetrennt, wodurch die Oeffnung 2 von etwa 20 mm Durchmesser ausgebildet ist, durch welche die einen Durchmesser von etwa 10 mm aufweisende, zylindrische Halogenbirne 4 hindurchragt. Der Durchmesser der Oeffnung 2 ist also etwa doppelt so gross wie der Durchmesser der (zylindrischen) Halogenbirne 4; der Querschnitt (die Querschnittsfläche) der Oeffnung 2 beträgt mithin et­wa das Vierfache und der Querschnitt des zwischen der Halogenbirne 4 und dem Oeffnungsrand 2 der Reflektorschale 1 gebildeten Ringspalts 21 etwa das Dreifache des Halogenbirnenquerschnitts. Der Querschnitt der Oeffnung 2 könnte auch ein anderes Mehrfaches des Halogenbirnenquer­schnitts betragen, etwa nur das 2-fache oder mehr als das Vierfache, wobei ein breiter Ringspalt 21 für die Kühlung der Fassung 3 wesent­lich und deshalb mindestens etwa das Vierfache bevorzugt ist. Bei Glühbirnen mit axial gewölbtem Kopf ist der Querschnitt der Oeffnung 2 (d.h. die vom Rand 9 umschlossene Fläche) um ein Mehrfaches grösser zu wählen als der grösste Querschnittsbereich des Glühbirnenkopfteils, der beim axialen Verschieben des U-Profilteils 7 in den Bereich der Oeffnung 2 gelangt. Die Fassung 3 kann auch unverschiebbar (ortsfest) in der Halterung 6, 7 angeordnet sein, wobei in diesem Fall der Quer­schnitt der Oeffnung 2 mindestens doppelt, vorzugsweise mindestens viermal so gross wie der Querschnitt des im Bereich der Oeffnung be­findlichen Teils der Glühbirne zu wählen ist.The reflector shell 1 and the two U-profile parts 6, 7 are preferably made of aluminum. In the exemplary embodiment shown in the drawing, the hemispherical reflector shell 1 has a diameter of 60 to 65 mm. A spherical cap or spherical cap is separated from it at a height of 2 to 4 mm, as a result of which the opening 2 of approximately 20 mm in diameter is formed, through which the cylindrical halogen bulb 4, which has a diameter of approximately 10 mm, projects. The diameter of the opening 2 is therefore approximately twice as large as the diameter of the (cylindrical) halogen bulb 4; the cross-section (the cross-sectional area) of the opening 2 is therefore approximately four times and the cross-section of the annular gap 21 formed between the halogen bulb 4 and the opening edge 2 of the reflector shell 1 is approximately three times the cross-section of the halogen bulb. The cross section of the opening 2 could also be another multiple of the halogen bulb cross section, for example only twice or more than four times, a wide annular gap 21 being essential for cooling the socket 3 and therefore at least approximately four times being preferred. In the case of light bulbs with an axially curved head, the cross section of the opening 2 (that is to say the area enclosed by the edge 9) is to be selected many times larger than the largest cross-sectional area of the light bulb head part, which reaches the area of the opening 2 when the U-profile part 7 is axially displaced . The socket 3 can also be arranged immovably (stationary) in the holder 6, 7, in which case the cross section of the opening 2 is at least twice, preferably at least four times as large as the cross section of the part of the light bulb located in the area of the opening is to be selected.

Die Fassung 3 ist im Zentrum der nur aus den beiden U-Profilteilen 6, 7 bestehenden Halterung völlig frei durch den Steg 13 im zwischen den beiden Schenkeln 10 gebildeten Luftdurchzugsraum 22 getragen. Der Luftdurchzugsraum 22, in den der breite Ringspalt 21 für den Luft­durchzug mündet, ist oben gänzlich offen und seitlich nur durch die beiden Schenkel 10 begrenzt, an den beiden dazwischenliegenden Seiten also auch gänzlich offen und - da der Abstand der Schenkel 10 grösser als der Durchmesser der Oeffnung 2 ist - gegenüber dem Ringspalt 21 radial nach aussen erweitert.The socket 3 is carried completely freely in the center of the bracket consisting of only the two U-profile parts 6, 7 by the web 13 in the air passage space 22 formed between the two legs 10. The air passage space 22, into which the wide annular gap 21 opens for the passage of air, is completely open at the top and only laterally delimited by the two legs 10, that is to say also completely open on the two sides lying in between and - since the distance between the legs 10 is greater than the diameter the opening 2 is widened radially outwards with respect to the annular gap 21.

Die frei im Luftdurchzugsraum 22 getragene Glühbirnenfassung 3 wird durch die von der Glühbirne 4 im Reflektorraum 20 erwärmte, durch den breiten Ringspalt 21 aufsteigende Luft umströmt und dadurch gekühlt. (Wenn die Leuchte nicht nach unten sondern nach oben gerichtet ist, erfolgt der Luftdurchzug umgekehrt). Dabei findet ein Austausch der vom Sockel (Fuss) der Halogenbirne bzw. der Fassung 3 stark erhitzten Luft mit der aufsteigenden Luft statt. Es hat sich gezeigt, dass sich der in der Fassung 3 befindliche Fuss der Halogenbirne 4 bei der be­schriebenen Anordnung trotz der Erwärmung durch die durch die Oeffnung zurückgestrahlte Wärmestrahlung vom in der Reflektorschale 1 befindli­chen Kopf der Birne 4 nicht oder jedenfalls nicht wesentlich über 120 °C erwärmt. Die Ventilationswirkung und Kühlung ist natürlich beson­ders wirksam und intensiv, wenn die Leuchte vertikal hängt. Auch in anderen Lagen wird aber eine gute Wirkung erzielt.The light bulb holder 3, which is carried freely in the air passage space 22, is flowed around by the air, which is heated by the light bulb 4 in the reflector space 20 and rises through the wide annular gap 21, and is thereby cooled. (If the luminaire is not directed downwards but upwards, the air flow is reversed). The air heated from the base (base) of the halogen bulb or socket 3 is exchanged with the rising air. It has been shown that the base of the halogen bulb 4 in the socket 3 in the arrangement described is not, or in any case not significantly above 120 ° C., despite the heating due to the heat radiation reflected by the opening from the head of the bulb 4 in the reflector shell 1 warmed. The ventilation effect and cooling is of course particularly effective and intensive when the lamp hangs vertically. However, a good effect is also achieved in other locations.
