Description

Die vorliegende Erfindung betrifft ein Beleuchtungssystem, insbesondere in Form einer Leuchte, zumindest einen Kühlkörper (10, 100) aufweisend, wobei der Kühlkörper mindestens eine erste Ausnehmung, insbesondere in Form einer Nut, aufweist, die eine erste Modulaufnahme für mindestens ein LED-Modul bildet, wobei das mindestens eine LED-Modul in der Ausnehmung einliegt oder einbringbar, insbesondere einschiebbar bzw. eingeschoben, ist, wobei die erste Ausnehmung eine Bodenwandung und begrenzende Seitenwandungen aufweist.The present invention relates to a lighting system, in particular in the form of a lamp, having at least one heat sink (10, 100), the heat sink having at least one first recess, in particular in the form of a groove, which forms a first module receptacle for at least one LED module , wherein the at least one LED module lies in the recess or can be introduced, in particular pushed in or pushed in, the first recess having a bottom wall and delimiting side walls.

Der Einsatz von LED-Modulen in Beleuchtungssystemen ist z.B. aus EP 1 590 996 B1 bekannt, wobei dort Sockel auf dem Kühlkörper befestigt werden, in die die LED-Module einsetzbar sind. Nachteilig hierbei ist, dass spezielle Sockel für die LED-Modulaufnahme benötigt werden, die den Herstellungsprozess erschweren und verteuern.The use of LED modules in lighting systems, for example, is out EP 1 590 996 B1 known, where there sockets are attached to the heat sink, in which the LED modules can be used. The disadvantage here is that special bases are required for the LED module receptacle, which makes the manufacturing process more difficult and expensive.

Ein ähnliches Beleuchtungssystem ist aus EP 2719938 A1 , US2010/0025721 A1 und DE 20 2008 011 979 U1 bekannt. Nachteilig bei diesen Systemen ist, dass die LED-Module mittels aufwendiger Stromschienen, Kontaktelementen, etc. mit elektrischer Energie versorgt werden.A similar lighting system is off EP 2719938 A1 , US2010/0025721 A1 and DE 20 2008 011 979 U1 known. The disadvantage of these systems is that the LED modules are supplied with electrical energy by means of complex busbars, contact elements, etc.

Aus US 2005/0207165 A1 ist eine LED-Leuchte mit einer Anschlusseinheit zum Anschließen eines kartenförmigen LED-Moduls, sowie für die Leuchte geeignete LED-Module bekannt. In einer Ausführungsform umfasst das LED-Modul dafür eine Kühlplatte auf der Rückseite des LED-Moduls, die zur Wärmeübertragung zwischen dem LED-Modul und einer Metalplatte der Anschlusseinheit dient, die ein Kühlelement bildet. Um einen zur Wärmeübertragung ausreichenden Anpressdruck zwischen dem LED-Modul und der Metalplatte zu erzeugen, können neben dem dafür nicht ausreichenden Klemmmechanismus des elektronischen Anschlusses zwischen LED-Modul und Anschlusseinheit weitere Klemmmittel, beispielsweise in Form vom elastischen Mitteln vorgesehen sein, die beispielsweise nach dem Einsetzen des LED-Moduls händisch in Position gebracht werden. Nachteilig ist, dass dieser Vorgang aufwändig ist.Out U.S. 2005/0207165 A1 discloses an LED lamp with a connection unit for connecting a card-shaped LED module, as well as LED modules suitable for the lamp. In one embodiment, the LED module includes a cooling plate on the back of the LED module for heat transfer between the LED module and a metal plate of the connection unit serves, which forms a cooling element. In order to generate a contact pressure between the LED module and the metal plate that is sufficient for heat transfer, in addition to the clamping mechanism of the electronic connection between the LED module and the connection unit, which is not sufficient for this purpose, further clamping means, for example in the form of elastic means, can be provided which, for example, after insertion of the LED module can be positioned manually. The disadvantage is that this process is complex.

Aus US 2011/0176308 A1 ist eine Leuchte mit mehreren Kühlelementen, in denen LED-Module einliegen, bekannt. Die Kühlelemente weisen dafür jeweils Ausnehmungen auf, die aus einer Bodenwandung, zwei Seitenwandungen und Auskragungen gebildet sind, wobei die LED-Module unter den Auskragungen liegen. Zur Fixierung der LED-Module in der Ausnehmung sind unter den Auskragungen in Ausführungsformen elastische Elemente eingeklemmt, die die LED-Module nach unten drücken oder es sind die LED-Module mittels von oben in die Auskragungen eingestanzte Ausbeulungen gegen die Bodenwandung gedrückt. Nachteilig ist, dass auch diese Befestigung aufwendig ist.Out U.S. 2011/0176308 A1 a lamp with several cooling elements in which LED modules are embedded is known. For this purpose, the cooling elements each have recesses which are formed from a base wall, two side walls and projections, with the LED modules lying under the projections. To fix the LED modules in the recess, elastic elements are clamped under the projections in embodiments, which press the LED modules downwards, or the LED modules are pressed against the bottom wall by means of bulges punched into the projections from above. The disadvantage is that this attachment is expensive.

Aufgabe der vorliegenden Erfindung ist es, ein Beleuchtungssystem bereitzustellen, bei dem die verwendeten LED-Module leicht austauschbar sind und zudem mit wenig Aufwand mit elektrischer Energie versorgt und in einfacher Weise gekühlt werden.The object of the present invention is to provide a lighting system in which the LED modules used can be easily replaced and are also supplied with electrical energy with little effort and cooled in a simple manner.

Diese Aufgabe wird erfindungsgemäß mit einem Beleuchtungssystem mit den Merkmalen des Anspruchs 1 gelöst. Weitere vorteilhafte Ausgestaltungen der Erfindung nach Anspruch 1 ergeben sich durch die Merkmale der auf den Anspruch 1 rückbezogenen Unteransprüche.According to the invention, this object is achieved with an illumination system having the features of claim 1 . Further advantageous refinements of the invention according to claim 1 result from the features of the subclaims which refer back to claim 1.

Die Erfindung zeichnet sich vorteilhaft dadurch aus, dass das in der Ausnehmung einliegende LED-Modul in Richtung der Bodenwandung durch mindestens eine der Seitenwandungen oder durch ein an dem Kühlkörper mittels, Schraubverbindung befestigbares oberes Teil druckbeaufschlagbar bzw. druckbeaufschlagt ist.The invention is advantageously characterized in that the LED module lying in the recess can be pressurized in the direction of the base wall by at least one of the side walls or by an upper part that can be fastened to the heat sink by means of a screw connection.

Die Ausnehmung kann durch eine Nut gebildet sein. Diese kann entweder U-förmig im Querschnitt ausgebildet sein, wobei dann die seitlichen Begrenzungswandungen keinen Hinterschnitt für die länglichen Seiten des LED-Moduls bilden und dieses durch ein zusätzliches oberes Teil gegen die Bodenwandung der Nut gedrückt werden, so dass eine gute Wärmeleitung vom LED-Modul zum Kühlkörper während des Betriebes stattfindet. Die seitlichen Begrenzungswandungen können auch Hinterschnitte aufweisen. Diese können schräg ausgebildet sein und damit eine Schwalbenschwanzführung bilden oder durch entsprechend einer T-Nut ausgebildet sein, so dass sich das LED-Modul lediglich von der Seite her in die Ausnehmung des Kühlkörpers einschieben lässt. Dabei ist es von Vorteil, wenn die Hinterschnitte derart ausgebildet sind, dass das LED-Modul zunächst leicht, insbesondere spielfrei in einen vorderen ersten Bereich der Ausnehmung einschiebbar ist, wonach danach anschließend sich der Querschnitt der Ausnehmung bzw. der Hinterschnitte verkleinert, so dass ein Anpressdruck auf das LED-Modul realisiert wird, durch den das LED-Modul gegen die Bodenwandung der Ausnehmung bzw. Nut gedrückt wird.The recess can be formed by a groove. This can either be U-shaped in cross section, in which case the lateral boundary walls do not form an undercut for the elongated sides of the LED module and this is pressed against the bottom wall of the groove by an additional upper part, so that good heat conduction from the LED Module to the heat sink takes place during operation. The lateral boundary walls can also have undercuts. these can be formed obliquely and thus form a dovetail guide or be formed by a corresponding T-slot, so that the LED module can only be pushed from the side into the recess of the heat sink. It is advantageous if the undercuts are designed in such a way that the LED module can initially be pushed easily, in particular without play, into a front first area of the recess, after which the cross section of the recess or the undercuts is then reduced, so that a Contact pressure is realized on the LED module, through which the LED module is pressed against the bottom wall of the recess or groove.

Die Versorgung des mindestens einen LED-Moduls erfolgt über elektrische Kontakte, die am LED-Modul angeordnet sind und welche beim vollständigen Einbringen bzw. Einschieben des LED-Moduls in die Ausnehmung mit elektrischen Kontakten des Beleuchtungssystems kontaktieren. In einer besonders bevorzugten Ausführungsform der Erfindung ist ein Versorgungsmodul vorgesehen, welches in die gleiche Ausnehmung oder eine zusätzliche zweite Ausnehmung des Kühlkörpers eingebracht oder angeordnet ist, wobei das Versorgungsmodul elektrische Kontakte aufweist, die derart angeordnet sind, dass sie mit den elektrischen Kontakten des LED-Moduls bei dessen vollständigem Einsetzen bzw. Einschieben kontaktieren. So können die elektrischen Kontakte jeweils an oder in den Stirnseiten des LED- und Versorgungsmoduls angeordnet sein. Es ist jedoch genauso gut möglich, die elektrischen Kontakte an Wandungsabschnitten anzuordnen, die parallel oder in einem Winkel zur Bodenwandung der Ausnehmung angeordnet sind. So können sich das LED-Modul und das Versorgungsmodul bereichsweise überlappen, wobei an den sich überlappenden und einander zugewandten Oberflächen die zusammenwirkenden elektrischen Kontakte angeordnet sind. Dabei ist darauf zu achten, dass die Kontakte von ihrer Form und Höhe derart ausgestaltet sind, dass sich ein guter Kontakt und eine hinreichend große Kontaktfläche ergeben, so dass keine zu großen Übergangswiderstände vorhanden sind.The at least one LED module is supplied via electrical contacts which are arranged on the LED module and which make contact with electrical contacts of the lighting system when the LED module is fully introduced or pushed into the recess. In a particularly preferred embodiment of the invention, a supply module is provided which is introduced or arranged in the same recess or an additional second recess of the heat sink, the supply module having electrical contacts which are arranged in such a way that they can be connected to the electrical contacts of the LED Contact the module when it is fully inserted or pushed in. The electrical contacts can each be arranged on or in the end faces of the LED and supply module. However, it is just as possible to arrange the electrical contacts on wall sections which are arranged parallel or at an angle to the bottom wall of the recess. The LED module and the supply module can thus overlap in some areas, with the interacting electrical contacts being arranged on the overlapping and mutually facing surfaces. Care must be taken here that the shape and height of the contacts are designed in such a way that good contact and a sufficiently large contact surface result, so that the contact resistances are not too great.

Die Form der Ausnehmung kann derart ausgebildet sein, dass das LED-Modul nur in einer bestimmten Ausrichtung in die Ausnehmung des Kühlkörpers einbringbar ist, so dass es nicht zu einer Verpolung kommen kann. So können die Ausnehmung und das LED-Modul in ihrer Längserstreckung Bereiche mit unterschiedlichen Querschnittsformen aufweisen, die derart ausgebildet sind, dass das LED-Modul nur in einer Ausrichtung in die Ausnehmung eingebracht werden kann. So kann z.B. das LED-Modul an einer Stirnseite breiter ausgebildet sein als der Bereich der Ausnehmung, in dem der schmalere Bereich des LED-Moduls im eingesetzten Zustand angeordnet ist, an dem die mindestens eine LED befestigt ist und welcher voran und damit zuerst in die Ausnehmung eingebracht bzw. eingeschoben wird.The shape of the recess can be designed in such a way that the LED module can only be introduced into the recess of the heat sink in a specific orientation, so that polarity reversal cannot occur. Thus, the recess and the LED module can have different areas in their longitudinal extent Have cross-sectional shapes that are designed such that the LED module can only be introduced into the recess in one orientation. For example, the LED module can be made wider on one end than the area of the recess in which the narrower area of the LED module is arranged when inserted, on which the at least one LED is attached and which is ahead and thus first in the Recess is introduced or pushed.

Das Versorgungsmodul kann ebenfalls gegen falsches Einbringen in die Modulaufnahme gesichert werden, wie das LED-Modul, wie vorangehend beschrieben.The supply module can also be secured against being incorrectly inserted into the module receptacle, like the LED module, as described above.

Nachfolgend wird anhand von Ausführungsbeispielen die Erfindung näher erläutert.

Die Figur 1 zeigt eine erste mögliche Ausführungsform des erfindungsgemäßen Beleuchtungssystems in Form einer Leuchte. Die Leuchte weist einen Kühlkörper 10 sowie ein daran befestigtes oberes Teil 20 auf. Der Kühlkörper 10 weist an seiner oberen Seite 10b eine Ausnehmung 10d auf, in die ein LED Modul 40 sowie ein Versorgungsmodul 30 einschiebbar ist. Der Kühlkörper 10 sowie das Teil 20 bilden zusammen seitliche Einschuböffnungen E und E', in die von der Seite her das LED-Modul 40 und das Versorgungsmodul 30 in die Ausnehmung des Kühlkörpers 10 einschiebbar sind. Der Kühlkörper 10 weist an seiner Unterseite Kühlrippen 10a auf. Im eingeschobenen Zustand schließen die beiden Module 30, 40 fluchtend mit der Außenwandung 10o des Kühlkörpers 10 und des oberen Teils 20 ab. Das obere Teil 20 weist eine zylindrische Wandung 10b mit einer Stirnseite 20a auf. In einer nicht erfindungsgemäßen Ausführungsform kann das obere Teil 20 auf den Kühlkörper 10 mittels Steckverbindung und eventuell Rastverbindungen verbunden sein. Erfindungsgemäß ist vorgesehen, dass das obere Teil 20 und der Kühlkörper 10 miteinander verschraubt sind. Nicht dargestellt ist eine Optik und/oder ein Reflektor, die bzw. der in dem Teil 20 angeordnet sein kann oder ist und eine fensterartige Öffnung aufweist, durch die das Leuchtmittel 40 C, in Form einer oder mehrerer LEDs, hindurch scheint. Die Optik kann z.B. aus einer Linse oder einem Linsensystem bestehen. Die fensterartige Öffnung ist dabei derart ausgebildet, dass die Oberfläche 10b des Kühlkörpers 10 sowie die beiden Module 30, 40 von außen nicht sichtbar sind.the figure 1 shows a first possible embodiment of the lighting system according to the invention in the form of a lamp. The lamp has a heat sink 10 and an upper part 20 attached thereto. The heat sink 10 has a recess 10d on its upper side 10b, into which an LED module 40 and a supply module 30 can be inserted. The heat sink 10 and the part 20 together form lateral insertion openings E and E′, into which the LED module 40 and the supply module 30 can be inserted from the side into the recess of the heat sink 10 . The cooling body 10 has cooling ribs 10a on its underside. When pushed in, the two modules 30 , 40 are flush with the outer wall 10o of the heat sink 10 and the upper part 20 . The upper part 20 has a cylindrical wall 10b with an end face 20a. In an embodiment not according to the invention, the upper part 20 can be connected to the heat sink 10 by means of a plug-in connection and possibly snap-in connections. According to the invention it is provided that the upper part 20 and the heat sink 10 are screwed together. Not shown is an optical system and/or a reflector, which can be or is arranged in part 20 and has a window-like opening through which illuminant 40C, in the form of one or more LEDs, shines. The optics can consist of a lens or a lens system, for example. The window-like opening is such formed that the surface 10b of the heat sink 10 and the two modules 30, 40 are not visible from the outside.

Die Figuren 1a bis 1c zeigen das Einschieben der beiden Module 30, 40 in die Leuchte, bestehend aus Kühlkörper 10 und oberen Teil 20. Der Kühlkörper 10 weist eine Ausnehmung 10d auf, die durch eine Schwalbenschwanznut gebildet ist. Selbstverständlich ist es genauso gut möglich eine andersartige hinterschnittene Nut, wie z.B. eine T-Nut, zu verwenden. Die Schwalbenschwanznut 10d bildet mit ihren seitlichen schrägen Wandungen 10e Hinterschnitte 10s, die mit den schrägen Seitenwandungsabschnitten 30f, 40f der Module 30, 40 zusammenwirken. Im Bereich der Einschuböffnungen E, E', sind in die Oberfläche des Kühlkörpers größere Ausnehmungen 10f, 10f' eingearbeitet, in denen die Kopfbereiche 30a, 40a der beiden Module 30, 40 zur Einlage gelangen, wie es in der Figur 1b bzw. 1c dargestellt ist. Erst wenn beide Module 30, 40 vollständig in den Kühlkörper 10 und dessen Ausnehmungen 10d und 10f, 10f' eingeschoben sind, ist das LED-Modul über die elektrischen Kontakte 30c und 40e miteinander elektrisch verbunden. Aufgrund der Ausgestaltung der Module 30, 40 sowie der entsprechenden Ausnehmungen 10d, 10f, 10f' ist die oder sind die LEDs 40d relativ zu dem Kühlkörper 10 bzw. der Leuchte eindeutig positioniert. Die Ausnehmungen 10f und 10f' können identisch ausgebildet sein, so dass die beiden Module 30, 40 auch zueinander vertauscht in die Ausnehmungen des Kühlkörpers 10 einschiebbar sind.the Figures 1a to 1c show the insertion of the two modules 30, 40 into the lamp, consisting of the heat sink 10 and the upper part 20. The heat sink 10 has a recess 10d, which is formed by a dovetail groove. Of course, it is just as possible to use a different type of undercut groove, such as a T-groove. The dovetail groove 10d forms undercuts 10s with its lateral inclined walls 10e, which interact with the inclined side wall sections 30f, 40f of the modules 30, 40. In the area of the insertion openings E, E', larger recesses 10f, 10f' are worked into the surface of the heat sink, in which the head regions 30a, 40a of the two modules 30, 40 are inserted, as is shown in FIG Figure 1b and 1c, respectively. Only when both modules 30, 40 are fully inserted into the heat sink 10 and its recesses 10d and 10f, 10f' is the LED module electrically connected to one another via the electrical contacts 30c and 40e. Due to the design of the modules 30, 40 and the corresponding recesses 10d, 10f, 10f', the LED or LEDs 40d is/are clearly positioned relative to the heat sink 10 or the lamp. The recesses 10f and 10f' can be of identical design, so that the two modules 30, 40 can also be inserted into the recesses of the heat sink 10 in reversed relation to one another.

Die Figur 2 zeigt eine Seitenansicht der Leuchte, bestehend aus Kühlkörper 10 und oberem Teil 20. Die fensterartige Öffnung E ist vor der hinterschnittenen Nut 10d, welche insbesondere bevorzugt als Schwalbenschwanzführung ausgeführt sein kann, angeordnet und von ihren Abmessungen derart gehalten, dass die Kopfbereiche 30a, 40a in die Öffnung E, E' hineingeschoben werden können.the figure 2 shows a side view of the lamp, consisting of heat sink 10 and upper part 20. The window-like opening E is arranged in front of the undercut groove 10d, which can particularly preferably be designed as a dovetail guide, and its dimensions are held in such a way that the head areas 30a, 40a in the opening E, E' can be pushed in.

Die Figur 3 zeigt die perspektivische Darstellung der beiden Module 30, 40. Das Versorgungsmodul 30 weist einen Kopfbereich 30a auf, der eine abgerundete Stirnseite 30g aufweist. An den Kopfbereich 30a schließt sich der vom Querschnitt kleinere Bereich 30b an, dessen Seitenwandlungen 30f schräg zur Oberfläche 10b des Kühlkörpers 10 angeordnet sind. An der Stirnseite des Bereichs 30b stehen 2 elektrische Kontakte 30c vor, die mit Buchsen 40e des LED-Moduls 40 zusammenwirken und in diese zur elektrischen Kontaktierung eingreifen. Aufgrund des kleineren Querschnitts des Bereichs 30b gelangt die Fläche 30h beim Einschieben in den Kühlkörper 10 gegen die Stirnwandung 10f (siehe Figur 2), wodurch das Versorgungsmodul 30 nicht weiter in den Kühlkörper 10 einschiebbar ist. Das LED-Modul weist ebenfalls einen Kopfbereich 40a auf, an den sich der Bereich 40b anschließt. Der Bereich 40b hat ebenso wie der Bereich 30b des Versorgungsmoduls 30 schräg ausgebildete Längsseiten 40f, die mit der Schwalbenschwanznut 10d des Kühlkörpers 10 zusammenwirken und durch die Module 30, 40 nicht zur Vorderseite (Stirnseite 20a) hin herausfallen können. Auf der Oberseite des Bereichs 40b ist das Leuchtmittel in Form einer oder mehrerer LEDs 40c angeordnet. Der Kopfbereich 40a bildet mit seiner überstehenden Wandung 40h einen Anschlag, mit dem das Modul 40 an der Stirnwandung 10f des Kühlkörpers 10 zur Anlage gelangt. Das Versorgungsmodul 30 kann über ein Kabel K an eine Versorgungsleitung oder eine vorgeschaltete Elektronik angeschlossen werden bzw. sein. Die Figur 3 zeigt ein Schubloch S, welches der einfachen Extraktion des LED-Moduls 40 mittels eines spitzen Gegenstandes (z.B. Büroklammer) dient. Die Figur 4 zeigt eine alternative Ausführungsform der Module 30' und 40', wobei die Module sich dadurch unterscheiden, dass sie sich im eingeschobenen Zustand entsprechend der Figur 1c bereichsweise mit ihren Bereichen 30b' und 40b' überlappen, sodass die Kontakte 30c' und 40e' miteinander in elektrischer Verbindung gelangen. Die Bereiche 30b' und 40b' sind hierfür im Querschnitt kleiner als der Querschnitt 40b' des LED-Moduls 40 ausgebildet. Das Versorgungsmodul 30' kann über ein Kabel K an eine Versorgungsleitung oder eine vorgeschaltete Elektronik angeschlossen werden bzw. sein. Wie in Figur 3 sieht man in Figur 4 ein Schubloch S' für die Extraktion des LED-Moduls 40. Zudem sind beispielhaft Kontaktfedern am Versorgungsmodul angeordnet, welche auf Kontaktflächen des LED-Moduls drücken und somit eine elektrische Verbindung sicherstellen.the figure 3 shows the perspective view of the two modules 30, 40. The supply module 30 has a head area 30a, which has a rounded end face 30g. The head area 30a is adjoined by the area 30b with a smaller cross section, the side walls 30f of which are arranged obliquely to the surface 10b of the heat sink 10 . At the front of the area 30b there are 2 electrical contacts 30c which interact with sockets 40e of the LED module 40 and engage in them for electrical contacting. Due to the smaller cross section of the area 30b, the surface 30h comes up against the end wall 10f when it is pushed into the heat sink 10 (see figure 2 ), As a result of which the supply module 30 cannot be pushed any further into the heat sink 10. The LED module also has a head area 40a, which is adjoined by area 40b. The area 40b, like the area 30b of the supply module 30, has sloping longitudinal sides 40f, which interact with the dovetail groove 10d of the heat sink 10 and cannot fall out through the modules 30, 40 to the front (end face 20a). The illuminant in the form of one or more LEDs 40c is arranged on the upper side of the region 40b. With its protruding wall 40h, the head region 40a forms a stop with which the module 40 comes to rest on the end wall 10f of the heat sink 10 . The supply module 30 can be connected via a cable K to a supply line or upstream electronics. the figure 3 shows a sliding hole S, which is used for easy extraction of the LED module 40 using a pointed object (eg a paper clip). the figure 4 shows an alternative embodiment of the modules 30 'and 40', the modules differ in that they are in the inserted state according to the Figure 1c partially overlap with their regions 30b 'and 40b', so that the contacts 30c 'and 40e' come into electrical contact with each other. For this purpose, the regions 30b′ and 40b′ have a smaller cross section than the cross section 40b′ of the LED module 40 . The supply module 30' can be connected via a cable K to a supply line or upstream electronics. As in figure 3 see in figure 4 a sliding hole S′ for the extraction of the LED module 40. In addition, contact springs are arranged on the supply module, for example, which press on the contact surfaces of the LED module and thus ensure an electrical connection.

Die Figur 5 zeigt eine erfindungsgemäße Ausführungsform der Leuchte, einen Kühlkörper 100 sowie ein oberes Teil 200 aufweisend. Das obere Teil 200 wird mit seinem Innengewinde 200g auf das Gewinde 100g des Kühlkörpers 100 aufgeschraubt, wobei die Gewinde 100g und 200g derartig ausgebildet sind, dass die Aussparung 200h mit der Nut 100p, 100m fluchtet, welche in die Oberfläche 100n des Kühlkörpers 100 eingearbeitet ist. An der Unterseite weist der Kühlkörper wiederum Kühlrippen 100a auf. Die Höhe des LED Moduls 400 ist an die Tiefe der Nut 100p angepasst, in der Art und Weise, dass die Oberseite des LED Moduls 400 leicht über die Oberseite 100n des Kühlkörpers ragt. Wie Figur 6 zu entnehmen ist, weist das obere Teil 200 eine horizontale Wandung 200c auf, die eine zentrische Ausnehmung 200d aufweist. Mit der Unterseite der Wandung 200c drückt das Oberteil 200 im vollständig aufgeschraubten Zustand das LED-Modul 400 gegen die Bodenfläche der Nut 100p, sodass ein guter Wärmeübergang zwischen LED-Modul 400 und Kühlkörper 100 gegeben ist. Die zentrische Ausnehmung 200d ist oberhalb der LED 400c angeordnet, sodass die LED durch die fensterartige Ausnehmung 200d hindurchscheinen kann. Das obere Teil 200 weist eine seitliche Ausnehmung 200h auf, welche durch das Lösen der Verschraubung (Verdrehen des oberen Teils 200 gegen den Uhrzeigersinn) vor die Nut 100p gedreht werden kann. Durch das teilweise Lösen der Verschraubung wird der Anpressdruck aufgehoben, so dass das LED-Modul 400 und ein evtl. Versorgungsmodul seitlich aus der Leuchte entnommen werden kann. Das Oberteil 200 kann mit seiner zylindrischen Wandung 200b als Reflektor dienen. Es ist jedoch auch möglich, dass ein zusätzlicher, insbesondere konisch ausgebildeter, Reflektor und/oder eine Optik in das Oberteil 200 eingesetzt wird.the figure 5 shows an embodiment of the lamp according to the invention, having a heat sink 100 and an upper part 200 . The upper part 200 is screwed with its internal thread 200g onto the thread 100g of the heat sink 100, the threads 100g and 200g being formed in such a way that the recess 200h is aligned with the groove 100p, 100m which is machined into the surface 100n of the heat sink 100. The heat sink again has cooling ribs 100a on the underside. The height of the LED module 400 is adapted to the depth of the groove 100p in such a way that the top of the LED module 400 protrudes slightly over the top 100n of the heat sink. As figure 6 can be seen, the upper part 200 has a horizontal wall 200c, which has a central recess 200d. With the underside of the wall 200c, the upper part 200 presses the LED module 400 against the bottom surface of the groove 100p when it is completely screwed on, so that there is good heat transfer between the LED module 400 and the heat sink 100. The central recess 200d is arranged above the LED 400c, so that the LED can shine through the window-like recess 200d. The upper part 200 has a lateral recess 200h, which can be turned in front of the groove 100p by loosening the screw connection (turning the upper part 200 counterclockwise). By partially loosening the screw connection, the contact pressure is released so that the LED module 400 and any power supply module can be removed from the side of the light. The upper part 200 can serve as a reflector with its cylindrical wall 200b. However, it is also possible that an additional, in particular conical, reflector and/or an optical system is inserted into the upper part 200 .

Die Figur 6 zeigt die beiden Teile 100, 200 getrennt voneinander. In der Bodenwandung der Nut 100p ist an ihrem einen Ende eine Ausnehmung 100r eingearbeitet, die dazu, dass das Kabel K, K' des Versorgungsmoduls herausgeführt werden kann. Das LED- und das Versorgungsmodul für die in den Figuren 4-6 dargestellten Leuchten können im Gegensatz zu den in den Figuren 3 und 4 dargestellten Modulen 30, 40, einen im Querschnitt anders ausgebildete Kopfbereiche 30a, 40a aufweisen. Sie können über ihre Längserstreckung hin eine konstante Breite aufweisen, welche unwesentlich kleiner als die Breite der Nut 100p ist.the figure 6 shows the two parts 100, 200 separately from each other. In the bottom wall of the groove 100p, a recess 100r is incorporated at one end, which allows the cable K, K' of the supply module to be led out. The LED and the supply module for the lights shown in Figures 4-6 can, in contrast to the Figures 3 and 4 modules 30, 40 shown, have a head region 30a, 40a of different design in cross section. They can have a constant width over their longitudinal extent, which is insignificantly smaller than the width of the groove 100p.

Es ist zudem möglich, dass der Kopfbereich 30a des Versorgungsmoduls 30, insbesondere von seiner Querschnittsform, anders ausgebildet ist als der Kopfbereich 40a des LED-Moduls 40. Bei dieser Ausführungsform müssen auch die Ausnehmungen 10f, 10f' an die verschiedenen Querschnittsformen der beiden Kopfbereiche 30a, 40a angepasst werden, so dass die beiden Module 30, 40 nicht vertauscht und auch nicht zwei LED-Module gleichzeitig eingeschoben werden können.It is also possible that the head area 30a of the supply module 30, in particular in terms of its cross-sectional shape, is designed differently than that Head area 40a of the LED module 40. In this embodiment, the recesses 10f, 10f' must also be adapted to the different cross-sectional shapes of the two head areas 30a, 40a, so that the two modules 30, 40 are not interchanged and neither are two LED modules at the same time can be inserted.

Die Figur 7 zeigt die perspektivische Ansicht einer weiteren möglichen erfindungsgemäßen Leuchte, die aus dem in Figur 8b dargestellten Kühlkörper 100 und dem in Figur 8a dargestellten oberen Teil 200 besteht. Das obere Teil 200 wird auf das Gewinde 100g des Kühlkörpers 100 aufgeschraubt, wonach dann der Bolzen 100t durch die Nut 200e des oberen Teils 200 hindurch in eine in der Kühlkörperoberfläche 100n vorgesehene Bohrung, welche optional ein Innengewinde aufweist, eingesetzt und dort verliersicher, insbesondere mittels Kleben oder Verschraubung, befestigt wird. Der Bolzen 100t dient als Sicherung, so dass das obere Teil 200 nicht mehr vollständig vom Kühlkörper 100 abgeschraubt werden kann. Durch den Bolzen 100t kann das obere Teil 200 nur noch um einen Teil einer Umdrehung relativ zum Kühlkörper 100 verdreht werden, wodurch das obere Teil 200 die in der Nut 100v befindlichen Module in Form des LED-Moduls und des Versorgungsmoduls nicht mehr mittels der Bodenwandung 200c gegen den Nutgrund 100m drückt und diese dadurch aus dem Kühlkörper herausgenommen und somit ersetzt werden können.the figure 7 shows the perspective view of another possible lamp according to the invention, which is from in Figure 8b shown heat sink 100 and in Figure 8a illustrated upper part 200 consists. The upper part 200 is screwed onto the thread 100g of the heat sink 100, after which the bolt 100t is then inserted through the groove 200e of the upper part 200 into a bore provided in the heat sink surface 100n, which optionally has an internal thread, and secured there, in particular by means of Gluing or screwing, is attached. The bolt 100t serves as a safeguard so that the upper part 200 can no longer be completely unscrewed from the heat sink 100. Due to the bolt 100t, the upper part 200 can only be rotated by part of a revolution relative to the heat sink 100, as a result of which the upper part 200 no longer connects the modules located in the groove 100v in the form of the LED module and the supply module by means of the bottom wall 200c presses against the bottom of the slot 100m and these can be removed from the heat sink and thus replaced.

Die Figuren 9a und 9b zeigen eine weitere alternative Ausführungsform, bei der der Verdrehwinkel begrenzende Bolzen 100t' in einer fensterartige Nut 200e' des oberen Teils 200 eingreift. Auch dieser Bolzen zu 100t' kann erst nach dem vollständigen Schrauben vom oberen Teil 200 mit dem Kühlkörper 100 eingeschraubt bzw. eingeklebt oder eingepresst werden. Ansonsten sind die in den Figuren 8a, 8b, 9a und 9b dargestellten Ausführungsformen funktionsidentisch zu der in den Figuren 5 und 6 dargestellten Ausführungsform.the Figures 9a and 9b show a further alternative embodiment, in which the twist angle limiting bolt 100t' engages in a window-like groove 200e' of the upper part 200. This bolt of 100t' can only be screwed in or glued in or pressed in after the upper part 200 has been completely screwed to the heat sink 100 . Otherwise they are in the Figures 8a, 8b, 9a and 9b illustrated embodiments functionally identical to that in the figures 5 and 6 illustrated embodiment.

Die Figuren 10 bis 12 zeigen ein weiteres mögliches Beleuchtungssystem, bestehend aus einem Kühlkörper 510, einem auf den Kühlkörper 510 aufschraubbaren oberen Teil 520, in welches ein Reflektor 560 einsetzbar. Der Reflektor 560 ist mittels eines an dem oberen Teil 520 befestigbarem hülsenförmigen Teils 570 verliersicher gehalten ist. Hierzu weist das Teil 570 einen radial nach innen weisenden Kragen 570k auf, so dass die fensterartige Öffnung 570f des Teils 570 kleiner als der Reflektor 560 ist, so dass der Reflektor beim Befestigen des Teils 570 am oberen Teil 520 mittels des Kragens 570k im oberen Teil 520 verliersicher gehalten ist. Es ist jedoch auch möglich, dass zusätzlich auch der Reflektor 560 gegen das obere Teil 520, insbesondere dessen Wandung 520c, andrückbar ist, so dass der Reflektor 560 fest in dem Beleuchtungssystem fixiert ist. Der Kühlkörper 510 ist grundsätzlich ähnlich aufgebaut bzw. ausgebildet wie die Kühlkörper der zuvor beschriebenen Ausführungsformen. So können die Seitenwandungen 510s der Ausnehmung 510p mit und ohne Hinterschnitt ausgebildet sein. Sofern sie ohne Hinterschnitt, d.h. senkrecht zur Bodenwandung 510v ausgebildet sind, so kann das LED-Modul 540 auch von oben in die Ausnehmung eingesetzt werden, sofern das obere Teil 520 vom Kühlkörper ganz abgeschraubt bzw. entfernt ist. In einer bevorzugten Variante weist jedoch das obere Teil 520 eine seitliche Ausnehmung 520h auf. Durch Verdrehen des auf den Kühlkörper 510 aufgeschraubten oberen Teils 520 ist es möglich, die Ausnehmung 520h fluchtend zur Ausnehmung bzw. Nut 510p auszurichten, dass das LED-Modul 540 von der Seite her durch die Ausnehmung 520h in die Nut 510p bzw. das Beleuchtungssystem einschiebbar ist. Eine Verdrehsicherung 510t, wie sie in den Ausführungsbeispielen gemäß der Figuren 7, 8a bis 9b dargestellt und beschrieben ist, ist ebenfalls vorgesehen, wobei der Stift 510t den möglichen Verdrehwinkelbereich von Kühlkörper 510 gegenüber dem oberen Teil 520, z.B. auf eine Viertelumdrehung begrenzt. Nachdem das LED-Modul 540 vollständig in die Ausnehmung 510p des Kühlkörpers 510 eingeschoben bzw. eingesetzt ist, und dessen elektrische Kontakte 540e mit den Kontakten 530c des in eine an die Ausnehmung 510p angrenzende Ausnehmung 510w einliegenden Versorgungsmoduls 530 in elektrischer Verbindung sind, kann das obere Teil 520 wieder am Kühlkörper 510 festgeschraubt werden, wodurch das LED-Modul 540 gegen die Bodenwandung 510v der Ausnehmung 510p druckbeaufschlagt ist.the Figures 10 to 12 show another possible lighting system, consisting of a heat sink 510, an upper part 520 that can be screwed onto the heat sink 510 and into which a reflector 560 can be inserted. The reflector 560 is held captively by means of a sleeve-shaped part 570 that can be fastened to the upper part 520 . For this purpose, the part 570 has a collar 570k pointing radially inwards, so that the window-like opening 570f of the part 570 is smaller than the reflector 560, so that the reflector is captively held in the upper part 520 when the part 570 is fastened to the upper part 520 by means of the collar 570k. However, it is also possible that the reflector 560 can also be pressed against the upper part 520, in particular its wall 520c, so that the reflector 560 is firmly fixed in the lighting system. The heat sink 510 is basically constructed or designed similarly to the heat sinks of the previously described embodiments. Thus, the side walls 510s of the recess 510p can be formed with and without an undercut. If they are designed without an undercut, ie perpendicular to the bottom wall 510v, the LED module 540 can also be inserted into the recess from above, provided that the upper part 520 is completely unscrewed or removed from the heat sink. In a preferred variant, however, the upper part 520 has a lateral recess 520h. By rotating the upper part 520 screwed onto the heat sink 510, it is possible to align the recess 520h with the recess or groove 510p, so that the LED module 540 can be inserted from the side through the recess 520h into the groove 510p or the lighting system is. An anti-rotation device 510t, as in the exemplary embodiments according to FIG figures 7 , 8a to 9b shown and described is also provided, wherein the pin 510t limits the possible angle of rotation of the heat sink 510 relative to the upper part 520, for example to a quarter of a turn. After the LED module 540 has been pushed or inserted completely into the recess 510p of the heat sink 510 and its electrical contacts 540e are electrically connected to the contacts 530c of the supply module 530 lying in a recess 510w adjoining the recess 510p, the upper Part 520 are again screwed to the heat sink 510, whereby the LED module 540 is pressurized against the bottom wall 510v of the recess 510p.

Die Ausnehmung 510w für das Versorgungsmodul 530 ist von seiner Tiefe und Länge her anders ausgebildet als die Ausnehmung 510p für das LED-Modul 540, so dass die Module 530, 540 nur in einer Richtung und Anordnung in das Beleuchtungssystem einsetzbar sind. Es ist jedoch ebenso möglich, dass die Tiefe der beiden Ausnehmungen gleich ausgebildet ist.The recess 510w for the supply module 530 is designed differently in terms of its depth and length than the recess 510p for the LED module 540, so that the modules 530, 540 can only be arranged in one direction and in the Lighting system can be used. However, it is also possible for the depth of the two recesses to be the same.

Das LED-Modul 540 hat an seiner einen den Kontakten 540e abgewandten Seite eine insbesondere fensterartige Ausnehmung, in die ein Werkzeug, z.B. in Form des dünnen Drahtes einer Büroklammer B, eingeführt werden kann, um das LED-Modul 540 aus der Ausnehmung 510p herauszuziehen.On its side facing away from the contacts 540e, the LED module 540 has, in particular, a window-like recess into which a tool, e.g. in the form of the thin wire of a paper clip B, can be inserted in order to pull the LED module 540 out of the recess 510p.
