Abstract

The paraboloidal plastic housing (1) has a top opening (6) above the bases (22,23) of the lamps (28,29). The opening is closed by a circular cover (5) centred on the vertical axis (4) and pressed upwards by an internal leaf spring (7) which is pivotable about the common axis (10) of two bearings (8,9) on the insides of supports (11,12) at opposite sides of the housing. The lamp bases are installed at the centre of a preferably paraboloidal concave reflector (15). For access, downward pressure on the cover forces it into the housing so that it can be pivoted to either side, leaving the opening unobstructed.

Description

Die Erfindung betrifft ein Gehäuse einer Operationsleuchte mit einer durch ein Abdeckteil verschließbaren Gehäuseöffnung, wobei das Abdeckteil über ein Federelement mit dem Gehäuse schwenkbar verbunden ist.The invention relates to a housing of an operating room lamp with a housing opening that can be closed by a cover part, the cover part being pivotably connected to the housing via a spring element.

Aus der US-PS 23 44 327 ist ein Leuchtengehäuse bekannt, dessen Reflektoröffnung durch ein schwenkbares Abdeckteil abschließbar ist. Das als Lichtaustrittsöffnung vorgesehene Abdeckteil ist über ein mit Federelementen versehenes Gelenk mit dem übrigen Leuchtengehäuse verbunden, wobei zusätzliche Arretierelemente zur Verriegelung des Abdeckteils vorgesehen sind. Es handelt sich dabei um eine verhältnismäßig aufwendige Verriegelungskonstruktion, die bei Störfällen in der Praxis, wie beispielsweise Lampenwechsel geschultes Personal erfordern; darüberhinaus sind die im Bereich der Außenperipherie des Leuchtengehäuses befindlichen Verriegelungselemente aufgrund ihrer komplexen Bauweise für Operationsleuchten nicht geeignet, da diese einen sehr hohen Desinfektionsaufwand erfordern und möglichst glatte Flächen zwecks rascher und zuverlässiger Sterilisation erwünscht sind.From US-PS 23 44 327 a lamp housing is known, the reflector opening can be locked by a pivotable cover part. The cover part provided as a light exit opening is connected to the rest of the lamp housing via a joint provided with spring elements, additional locking elements being provided for locking the cover part. It is a relatively complex locking structure that requires trained personnel in the event of malfunctions in practice, such as changing lamps; moreover, the locking elements located in the area of the outer periphery of the luminaire housing are not suitable for operating lights due to their complex construction, since these require a very high disinfection effort and smooth surfaces are desirable for the purpose of quick and reliable sterilization.

Weiterhin ist aus der DE 36 33 609 A1 eine Beleuchtungsvorrichtung mit mehreren Lichtquellen in einer als Abdeckteil ausgebildeten Lampenhalteanordnung und mit einem die Lichtquellen im radialen Abstand zur Symmetrieachse der Vorrichtung umgebenden ersten Reflektor bekannt; die von den Lichtquellen ausgehende Strahlung wird dabei zunächst auf einen unterhalb der Lichtquellen angeordneten drehbaren zweiten Reflektor mit den einzelnen Lichtquellen zugeordneten unterschiedlichen Oberflächenbereichen gerichtet, und dann zum ersten Reflektor weitergeleitet. Durch Drehung des zweiten Reflektors wird die zum ersten Reflektor gespiegelte Strahlung in ihrer Intensität eingestellt; es handelt sich hierbei um eine verhältnismäßig aufwendige Konstruktion.Furthermore, DE 36 33 609 A1 discloses an illumination device with a plurality of light sources in a lamp holding arrangement in the form of a cover part and with a first reflector surrounding the light sources at a radial distance from the axis of symmetry of the device; The radiation emanating from the light sources is first directed onto a rotatable second reflector arranged below the light sources with different surface areas assigned to the individual light sources, and then passed on to the first reflector. By rotating the second reflector, the one reflected to the first reflector is mirrored Radiation set in its intensity; it is a relatively complex construction.

Aus der FR-PS 805 078 ist eine Lampe bekannt, die zur Abdeckung von Glühbirnen zwecks Verdunkelung um Scharniere schwenkbare Hauben aufweist; bei einer Lampe mit Reflektor ist dieser mit Ausnehmungen zur Einfügung der Hauben in geöffnetem Zustand versehen; eine Haube weist eine Öffnung mit Abdeckklappe auf, so daß im geschlossenen Zustand der Hauben ein schwacher Lichtstrahl nach außen treten kann.From FR-PS 805 078 a lamp is known which has covers which can be pivoted about hinges to cover light bulbs for the purpose of darkening; in the case of a lamp with reflector, this is provided with recesses for inserting the hoods in the open state; a hood has an opening with a cover flap, so that when the hoods are closed, a weak beam of light can exit.

Weiterhin ist es aus der Betriebsanleitung zur Operationsleuchte Hanaulux 2000 Duo (Druckvermerk: 56351038/02.92 Ko) bekannt, zum Lampenwechsel eine auf der Rückseite des Leuchtengehäuses aufgebrachte Gehäusekappe zu entfernen und anschließend wieder aufzusetzen; dabei muß eine Verdrehsicherung betätigt werden.Furthermore, it is known from the operating instructions for the Hanaulux 2000 Duo surgical light (printed note: 56351038 / 02.92 Ko) to remove a housing cap on the back of the light housing and replace it afterwards; an anti-rotation device must be activated.

Die Erfindung stellt sich die Aufgabe, ein Leuchtengehäuse für Operationsleuchten zu schaffen, das sowohl einen einfachen Aufbau als auch einen einfachen Zugriff in das Gehäuseinnere durch ein mittels Federelement belastetes Abdeckteil des Gehäuses - beispielsweise bei Lampenwechsel - ermöglicht, wobei im äußeren Bereich möglichst glatte Oberflächen zwecks einfacher Desinfektion angestrebt werden.The invention has for its object to provide a luminaire housing for surgical lights, which allows both a simple structure and easy access to the interior of the housing by a spring element loaded by a cover part of the housing - for example when changing lamps - with the smoothest possible surfaces in the outer area simple disinfection are aimed for.

Die Aufgabe wird erfindungsgemäß durch die Merkmale des Anspruchs 1 gelöst.The object is achieved by the features of claim 1.

Als besonders vorteilhaft erweist sich die einfache Handhabung, beispielsweise beim Lampenwechsel auch durch technisch ungeschultes Personal erwiesen; weiterhin können die für Operationsräume strengen Anforderungen an Sterilität der benutzten Geräte auf verhältnismäßig einfache Weise aufgrund glatter, geschlossener Gehäuse-Oberflächen erfüllt werden.The simple handling has proven to be particularly advantageous, for example when changing the lamp, even by technically untrained personnel; Furthermore, the strict sterility requirements for the equipment used for operating rooms can be met in a relatively simple manner due to the smooth, closed housing surfaces.

Weitere vorteilhafte Ausgestaltungen der Erfindung nach Anspruch 1 sind in den Ansprüchen 2 bis 6 angegeben.Further advantageous embodiments of the invention according to claim 1 are specified in claims 2 to 6.

Ein Austausch der Leuchtmittel ist somit ohne Verwendung von Werkzeug möglich. Bei Öffnen des Leuchtengehäuses bleiben vorteilhafterweise dessen Schwerpunkt und Masse erhalten. Der Deckel muß weder weggelegt werden noch hängt er unkontrolliert am Leuchtenkörper.The lamps can therefore be replaced without the use of tools. When the luminaire housing is opened, its center of gravity and mass are advantageously retained. The lid does not have to be put away nor does it hang uncontrollably on the lamp body.

Figur 1a zeigt in einer perspektivischen Explosionszeichnung das Leuchten-Gehäuse 1 vor seiner Zusammensetzung, wobei die Haube 2 vom Gehäuse-Unterteil 3 abgenommen dargestellt ist; die Haube 2 besteht aus einem nach außen konvex gebogenen paraboloidartigen Hohlkörper aus Kunststoff, sie ist im Scheitelbereich entlang der Längsachse 4 des Leuchten-Gehäuses mit einer Öffnung 6 versehen, die mit einem federnd gelagerten Abdeckteil 5 durch eine von innen ausgeübte Preßkraft zu schließen ist. Die Abdeckung 5 ist über eine als Federelement 7 ausgebildete Blattfeder mit dem Gehäuse-Unterteil 3 des Leuchten-Gehäuses verbunden, wobei die Blattfeder an ihren beiden Enden jeweils in einem Lager 8, 9 des Unterteils so gehalten wird, daß sie zusammen mit dem darauf befestigten Abdeckteil 5 sowohl zur Öffnung 4 hin oder als auch von ihr weg verschwenkt werden kann. Die Lager 8, 9 sind auf sich gegenüberliegenden Innenflächen von Tragelementen 11, 12 des Unterteils 3 in einer Schwenkachse 10 angeordnet; wenigstens eines der beiden Tragelemente 11, 12, ist zur schwenkbaren Befestigung des Leuchten-Gehäuses 1 an einem hier nur teilweise dargestellten Gelenkarm 16 der Deckenaufhängung vorgesehen.FIG. 1 a shows an exploded perspective view of the lamp housing 1 before its assembly, the hood 2 being shown removed from the lower housing part 3; the hood 2 consists of an outwardly convex curved paraboloid-like hollow body made of plastic, it is provided in the apex area along the longitudinal axis 4 of the lamp housing with an opening 6, which can be closed with a resiliently mounted cover part 5 by an internal pressing force. The cover 5 is connected via a leaf spring designed as a spring element 7 to the lower housing part 3 of the lamp housing, the leaf spring being held at both ends in a bearing 8, 9 of the lower part in such a way that they are fastened together with it Cover part 5 can be pivoted both towards the opening 4 or away from it. The bearings 8, 9 are arranged on opposite inner surfaces of support elements 11, 12 of the lower part 3 in a pivot axis 10; at least one of the two support elements 11, 12 is provided for the pivotable attachment of the lamp housing 1 to an articulated arm 16 of the ceiling suspension, which is only partially shown here.

Die Innenfläche des auf dem Gehäuse-Unterteil 3 befindlichen Reflektors 15 ist zylindersymmetrisch - vorzugsweise als Hohlparaboloid - ausgebildet, wobei die durch die Öffnung 13 des Reflektors verlaufende Zylinderachse der Längsachse 4 der Haube 2 entspricht; in Öffnung 13 sind zwei zueinander parallel angeordnete Strahlerlampen eingesetzt, von denen beispielsweise eine erste als Hauptleuchte und eine zweite als Reserveleuchte dient, wobei die Umschaltung bei Ausfall der Hauptleuchte durch eine im Leuchtengehäuse 1 befindliche Umschaltautomatik mit entsprechender Signalanzeige für den Benutzer vorgenommen wird.The inner surface of the reflector 15 located on the lower housing part 3 is formed cylindrically symmetrically - preferably as a hollow paraboloid - the cylinder axis running through the opening 13 of the reflector corresponding to the longitudinal axis 4 of the hood 2; In opening 13 two mutually parallel lamp lamps are used, of which, for example, a first serves as a main lamp and a second as a reserve lamp, the switchover being carried out in the case of a failure of the main lamp by an automatic switchover located in the lamp housing 1 with a corresponding signal display for the user.

In Figur 1 sind lediglich die Sockel 22, 23 der mit ihren Lampenkolben in Richtung Strahlenaustritt 24 eingesetzten Lampen zu erkennen, die zugehörigen Lampenkolben sind nicht erkennbar.In FIG. 1 only the bases 22, 23 of the lamps used with their lamp bulbs in the direction of the beam exit 24 can be seen, the associated lamp bulbs cannot be seen.

Haube 2 ist mit zwei sich seitlich gegenüberliegenden Ausbuchtungen 17, 18 versehen, die den Innenraum des Leuchtengehäuses 1 beim Aufsetzen auf die Tragelemente 11, 12 und das Unterteil 3 mittels Arretierung nach außen hin dichtend abschließen. Abdeckteil 5 besteht aus einem ellipsenförmigen Deckel 20, der in seinem unterem Bereich mit einem umlaufenden Flansch 21 versehen ist, wobei der untere Teil auf dem als Blattfeder dienenden Federelement 7 formschlüssig fest verbunden ist.Hood 2 is provided with two laterally opposite bulges 17, 18 which seal off the interior of the lamp housing 1 when it is placed on the support elements 11, 12 and the lower part 3 by means of a locking mechanism. Cover part 5 consists of an elliptical cover 20, which is provided in its lower region with a circumferential flange 21, the lower part being firmly connected to the spring element 7 serving as a leaf spring.

Beim Aufsetzen von Haube 2 auf Gehäuse-Unterteil 3 tritt gemäß Figur 2 Deckel 20 des Abdeckteils 5 in die Öffnung 6 der Haube 2 ein, während der umlaufende Flansch 21 gegen den inneren Rand von Öffnung 6 so gepreßt wird, daß dieser durch Kraftschluß aufgrund der Wirkung von Federelement 7 geschlossen wird; dabei bilden die Außenoberfläche von Haube 2 und die Oberfläche von Deckel 20 zusammen praktisch eine geschlossene Außenfläche, wie sie sich insbesondere für Desinfektionsanforderungen im Operationsbereich bewährt hat. Gehäuse-Unterteil 3 weist einen die Tragelemente 11, 12 sowie den Reflektor 15 und Strahlenaustritts-Scheibe tragenden Rahmen 26 auf, der mit Befestigungsmitteln 27 zum Montieren von Reflektor 15, Strahlenaustritts-Scheibe sowie hier nicht dargestellten Befestigungsmitteln zwecks Arretierung der Haube 2 versehen ist. Weiterhin sind zwecks besserer Übersicht in der Figur keine der zur Stromversorgung der Lampen erforderlichen Leitungen dargestellt.When hood 2 is placed on lower housing part 3, according to FIG. 2, cover 20 of cover part 5 enters opening 6 of hood 2, while circumferential flange 21 is pressed against the inner edge of opening 6 in such a way that it is closed by frictional engagement due to Effect of spring element 7 is closed; the outer surface of hood 2 and the surface of lid 20 together form practically a closed outer surface, as has proven particularly useful for disinfection requirements in the operating area. The lower housing part 3 has a frame 26 which carries the support elements 11, 12 and the reflector 15 and the radiation exit disk and is provided with fastening means 27 for mounting the reflector 15, radiation exit disk and fastening means (not shown here) for locking the hood 2. Furthermore, for the sake of a better overview, none of the lines required to power the lamps are shown in the figure.

Ein nachfolgender Lampenwechsel ist unproblematisch dadurch möglich, daß durch Druck auf Abdeckteil 5 entlang der Achse 4 eine Deformation der Blattfeder 7 hervorgerufen wird, so daß Deckel 20 des Abdeckteils unter den Rand der Öffnung 6 der schalenförmig ausgebildeten Haube gedrückt und entlang der Schwenkrichtung der Blattfeder um Achse 10 unterhalb des Randes der Öffnung 6 verschoben werden kann; es ist somit auf einfache unproblematische Weise möglich, durch Verschieben von Abdeckteil 5 einen Austausch einer der beiden Lampen bzw. beider Lampen, deren Sockel mit 22, 23 bezeichnet sind, vorzunehmen.A subsequent lamp change is unproblematically possible in that a deformation of the leaf spring 7 is caused by pressure on the cover part 5 along the axis 4, so that the cover 20 of the cover part is pressed under the edge of the opening 6 of the bowl-shaped hood and around along the pivoting direction of the leaf spring Axis 10 can be moved below the edge of the opening 6; it is thus possible in a simple and unproblematic manner to replace one of the two lamps or both lamps, the bases of which are designated 22, 23, by moving cover part 5.

Eine Schwenkrichtung des Abdeckteils 5 ist entlang der mit Ziffer 30, 31 bezeichneten Pfeile d.h. um Achse 10 möglich. Nach ordnungsgemäßem Einsatz der Glühlampen 22, 23 wird Abdeckteil 5 manuell wiederum in seine ursprüngliche Position entlang der Achse 4 zurückgeführt, so daß die Öffnung 6 durch Deckel 20 des Abdeckteils 5 geschlossen ist.A pivoting direction of the cover part 5 is possible along the arrows labeled 30, 31, ie around axis 10. After proper use of the bulbs 22, 23, the cover part 5 is manually returned to its original position along the axis 4, so that the opening 6 is closed by the cover 20 of the cover part 5.

Figur 3a zeigt einen vertikalen Schnitt durch Leuchtengehäuse 1 entlang der Achse 10, bzw. Lampenachse 4; Reflektor 15 liegt mit dem flanschartigen Rand 35 seiner Öffnung auf dem Rand der Strahlenaustritts-Scheibe 32 auf, die ihrerseits den Rand 33 der Öffnung 34 des Leuchten-Gehäuses 1 abdeckt; der umlaufende Flansch 35 des Reflektors 15 ist zusammen mit dem Rand der Strahlenaustritts-Scheibe 32 im Randbereich 33 des Leuchten-Gehäuses mittels Schrauben bzw. Bolzen arretiert, wobei die Öffnung 34 des Leuchten-Gehäuses dicht abgeschlossen ist, um den strengen hygienischen Vorschriften im Operationsraum zu genügen.FIG. 3a shows a vertical section through lamp housing 1 along axis 10 or lamp axis 4; The reflector 15 lies with the flange-like edge 35 of its opening on the edge of the radiation exit disc 32, which in turn covers the edge 33 of the opening 34 of the lamp housing 1; the circumferential flange 35 of the reflector 15 is locked together with the edge of the radiation exit disk 32 in the edge region 33 of the lamp housing by means of screws or bolts, the opening 34 of the lamp housing being sealed off in order to comply with the strict hygienic regulations in the operating room to suffice.

Figur 3a zeigt zwischen dem Randbereich der Öffnung 6 von Haube 2 und dem Randbereich des Abdeckteils 5 einen Spalt, wie er üblicherweise beim Ausüben von Preßdruck entlang der Achse 4 auf Abdeckteil 5 entsteht. Es ist sodann möglich, Abdeckteil 5 um Schwenkachse 10 soweit zu verschwenken, daß ein manueller Eingriff durch Öffnung 6 der Haube möglich ist und somit eine einfache Wartung der Leuchtmittel durch Austausch gewährleistet werden kann.FIG. 3a shows a gap between the edge area of the opening 6 of the hood 2 and the edge area of the cover part 5, as is usually the case when pressure is exerted on the cover part 5 along the axis 4. It is then possible to pivot cover part 5 about pivot axis 10 to such an extent that manual intervention through opening 6 of the hood is possible and simple maintenance of the lamps can be ensured by replacement.
