According to the invention, the housing is divided into at least two sections (A1, A2), the first section (A2) having space for operating devices and a second section (A1, A3), to the side, containing at least one LED cluster and each LED cluster being coupled to means for dissipating the heat that arises during operation.

Description

Fassadenleuchte mit Leuchtdioden  Facade luminaire with LEDs
Die Erfindung betrifft eine Fassadenleuchte mit einem Gehäuse zur Aufnahme von The invention relates to a facade light with a housing for receiving
Leuchtmitteln und Betriebsgeräten. Insbesondere dann, wenn mit Fassadeleuchten Farbspiele auf einer Fassade dargestellt werden sollen, kommen heutzutage meist Leuchtdioden (LED) als Leuchtmittel zum Einsatz. Bulbs and control gear. In particular, when with facade lights color games are to be displayed on a facade, nowadays most light-emitting diodes (LED) are used as bulbs.
Aus der WO 2005/024291 A2 ist eine Fassadenleuchte bekannt, bei der Leuchtdioden unterschiedlicher Farben in einer Reihe hintereinander angeordnet sind. Jeder einzelnen Leuchtdiode ist eine Optik zugeordnet. Das Gehäuse ist so ausgebildet, dass es auch zur Kühlung der Leuchtdioden geeignet ist. From WO 2005/024291 A2 a facade light is known, are arranged in the light emitting diodes of different colors in a row one behind the other. Each individual LED is assigned an optic. The housing is designed so that it is also suitable for cooling the light-emitting diodes.
Nachteilig bei der vorbekannten Fassadenleuchte ist, dass deren Bauhöhe verhältnismäßig hoch ist. Aufgabe der vorliegenden Erfindung ist es, eine Fassadenleuchte der eingangs genannten Art so weiterzubilden, dass diese möglichst kleinbauend ausgeführt werden kann. Hierzu ist eine Reihe von Maßnahmen erforderlich, die in den kennzeichnenden Merkmalen des Anspruchs 1 angeführt sind. Erfindungsgemäß werden die Leuchtdioden in LED-Clustern angeordnet, wobei jedem LED- Cluster eine Optik zugeordnet ist, durch die das von den Leuchtdioden des LED-Clusters abgegebene Licht hindurch tritt. Hierbei ist die Optik derart angeordnet und ausgestaltet, dass das von den Leuchtdioden des LED-Clusters abgegebene Licht durch die Optik hindurch tritt, wobei die Optik derart ausgelegt ist, dass diese eine elliptische Lichtverteilung erzeugt. A disadvantage of the known facade light that their height is relatively high. Object of the present invention is to develop a facade lamp of the type mentioned so that it can be performed as small as possible. For this purpose, a number of measures are required, which are given in the characterizing features of claim 1. According to the light emitting diodes are arranged in LED clusters, each LED cluster is associated with an optics through which passes the light emitted by the LEDs of the LED cluster light. In this case, the optics are arranged and configured such that the light emitted by the light-emitting diodes of the LED cluster passes through the optics, the optics being designed such that it generates an elliptical light distribution.
Hierdurch wird erreicht, dass ein weiter Bereich einer Fassade von einem zentralen Punkt, nämlich einer in etwa punktförmigen Lichtquelle, aus gleichmäßig beleuchtet werden kann. Werden mehrere Fassadenleuchten beanstandet zueinander und nebeneinander angeordnet, so kann durch Überlagerung der einzelnen elliptischen Lichtverteilungen zumindest angenährt ein breiter Streifen einer Fassade beleuchtet werden. This ensures that a wide area of a façade can be uniformly illuminated from a central point, namely an approximately punctiform light source. If several façade luminaires are objected to one another and arranged next to one another, then by overlaying the individual elliptical light distributions, a broad strip of a façade can be illuminated at least approximately.
Ferner ist wesentlich, dass das Gehäuse in wenigstens zwei Abschnitte unterteilt ist, wobei in einem ersten Abschnitt Raum für Betriebsgeräte ist und in einem zweiten seitlich neben dem ersten Abschnitt angeordneten Abschnitt wenigstens ein LED-Cluster angeordnet ist. Ferner ist jeder der LED-Cluster gekühlt und hierzu mit entsprechenden Mitteln zum Abführen der während des Betriebs der Leuchtdioden entstehenden Wärme gekoppelt. In Summe ermöglichen alle diese Merkmale, dass die Fassadenleuchte mit sehr geringen Abmessungen, insbesondere mit sehr geringer Bauhöhe ausgeführt werden kann. Eine schmale Furthermore, it is essential that the housing is subdivided into at least two sections, wherein in a first section there is room for operating devices and in a second section arranged laterally next to the first section at least one LED cluster is arranged. Further, each of the LED clusters is cooled and coupled thereto by appropriate means for dissipating the heat generated during operation of the light emitting diodes. In total allow all these features that the facade light can be made with very small dimensions, especially with very low height. A narrow one
Ausführungsform für die Leuchte wird hierbei vorzugsweise dadurch erzielt, dass die LED- Cluster nebeneinander, im Wesentlichen entlang einer Geraden angeordnet sind. Embodiment for the luminaire is preferably achieved in that the LED clusters are arranged side by side, substantially along a straight line.
Bei Fassadenleuchten ist die geringe Bauhöhe unter anderem deshalb von großer Bedeutung, weil Fassadenleuchten in der Regel auf Fensterbrüstungen oder Fassadenelementen montiert werden, man aber aus architektonischen Gründe bestrebt ist, die Fassadenleuchte so zu platzieren, dass sie von einem Betrachter des Gebäudes nicht oder zumindest kaum gesehen wird. Weist die Fassadenleuchte eine ausreichend geringe Bauhöhe auf, so kann sie ab einem bestimmten Betrachtungswinkel nicht mehr gesehen werden, weil sie von Fensterbrüstungen oder Fassadenelementen verdeckt ist. Among façade luminaires, the low overall height is of great importance, among other things, because façade luminaires are usually mounted on window parapets or façade elements, but for architectural reasons, it is endeavored to place the façade luminaire in such a way that it is not or at least barely visible to a viewer of the building is seen. If the façade luminaire has a sufficiently low overall height, then it can no longer be seen from a certain viewing angle, because it is covered by window parapets or façade elements.
In einer bevorzugten Ausführungsform weist die Fassadenleuchte ein Gehäuse auf, welches in drei Abschnitte unterteilt ist, wobei im mittleren Abschnitt Raum für Betriebsgeräte ist und in den seitlichen Abschnitten jeweils wenigstens ein LED-Cluster angeordnet ist. In dieser Anordnung ist es in besonders vorteilhafter Weise möglich die Überlagerung der elliptischen Lichtverteilung und damit die streifenförmige Beleuchtung einer Fassade zu realisieren. Dies gilt umso mehr bei einer Ausführungsform der Erfindung bei der in den seitlichen In a preferred embodiment, the façade luminaire has a housing which is subdivided into three sections, wherein in the middle section there is space for operating devices and in each case at least one LED cluster is arranged in the lateral sections. In this arrangement, it is possible in a particularly advantageous manner to realize the superposition of the elliptical light distribution and thus the strip-like illumination of a facade. This is even more true in an embodiment of the invention in the case of the lateral
Abschnitten jeweils zwei LED-Cluster angeordnet sind. Sections each two LED clusters are arranged.
Die Mittel zum Abführen der Wärme können gemäß einer bevorzugten Ausführungsform Luftspalte aufweisen, welche im Gehäuse, insbesondere zwischen einem Aufnahmebereich für die LED-Cluster und einer umlaufenden Gehäusewand ausgebildet sind. Es hat sich gezeigt, dass durch diese Maßnahme trotz kompakter Bauweise der Leuchte ein sehr effektives Abführen der Wärme erzielt werden kann, was für einen zuverlässigen Betrieb der Leuchte unerlässlich ist. The means for dissipating the heat may according to a preferred embodiment have air gaps, which are formed in the housing, in particular between a receiving area for the LED cluster and a circumferential housing wall. It has been shown that a very effective dissipation of heat can be achieved by this measure despite compact design of the lamp, which is essential for reliable operation of the lamp.
Alternativ oder ergänzend zur Verwendung der Luftspalte können die LED-Cluster allerdings auch mittels eines oder mehrerer Kühlkörper gekühlt werden, wobei diese ebenfalls in den seitlichen Abschnitten des Gehäuses platziert bzw. ausgebildet sind. Ein LED-Cluster besteht aus wenigstens zwei Leuchtdioden, bevorzugt drei Leuchtdioden unterschiedlicher Farbe und oder Farbtemperatur. Die Leuchtdioden werden bevorzugt auf einer ersten Seite von Platinen, insbesondere Metallkernplatinen, angeordnet. Die Platinen stehen hierbei auf der der ersten Seite gegenüberliegenden Seite in wärmeleitender Verbindung mit dem Kühlkörper. Alternatively or in addition to the use of the air gaps, however, the LED clusters can also be cooled by means of one or more heat sinks, wherein these are also placed or formed in the lateral sections of the housing. An LED cluster consists of at least two light emitting diodes, preferably three light emitting diodes of different color and or color temperature. The light-emitting diodes are preferably arranged on a first side of circuit boards, in particular metal core boards. The boards are in this case on the opposite side of the first side in heat-conducting connection with the heat sink.
Vorzugsweise kann der Kühlkörper einstückig ausgebildet sein und ist dementsprechend bei einer Unterteilung des Gehäuses in drei Abschnitte ebenfalls in drei Abschnitte unterteilt. Im ersten Abschnitt ist der Kühlkörper mit der im ersten seitlichen Abschnitt des Gehäuses angeordneten Platine wärmeleitend verbunden, im zweiten bzw. mittleren Abschnitt überbrückt der Kühlkörper den Raum für die Betriebsgeräte und im zweiten seitlichen Abschnitt ist der Kühlkörper mit der im dritten Abschnitt des Gehäuses angeordneten Platine wärmeleitend verbunden. Preferably, the heat sink may be integrally formed and is accordingly also divided into three sections when dividing the housing into three sections. In the first section is the heat sink with the first side section of the housing arranged board thermally conductively connected in the second or middle section of the heat sink bridges the space for the operating devices and in the second lateral portion of the heat sink is thermally conductively connected to the arranged in the third portion of the housing board.
Beim Gehäuse kann, sofern es durch ein Gehäuseunterteil und durch ein Gehäuseoberteil gebildet ist, das Gehäuseunterteil als Kühlkörper ausgeführt sein. In diesem Fall ist für die Fertigung des Gehäuseunterteils als Aludruckguss eine bevorzugte Möglichkeit. Bevorzugt weist der Kühlkörper im Bereich der seitlichen Abschnitte Kühlrippen auf, die sich ausgehend von einer Seite einer Basis erheben, wobei die Höhe der Kühlrippen in etwa der Tiefe des Raumes entspricht, der zur Aufnahme von Betriebsgeräten vorgesehen ist. When the housing can, if it is formed by a lower housing part and by an upper housing part, the lower housing part be designed as a heat sink. In this case, a preferred option is for the production of the housing lower part as aluminum die cast. Preferably, the heat sink in the region of the lateral sections on cooling fins, which rise from one side of a base, wherein the height of the cooling fins corresponds approximately to the depth of the space which is provided for receiving operating devices.
Hierdurch entsteht ein Körper, dessen Außenkontur einem Quader angenähert ist. This creates a body whose outer contour is approximated to a cuboid.
Vorzugsweise kann die der zuvor genannten Seite gegenüberliegende Seite der Basis als Kontaktfläche zwischen Platine und Kühlkörper dienen. Preferably, the opposite side of the base from the aforementioned side can serve as a contact surface between the printed circuit board and the heat sink.
Der Kühlkörper kann im mittleren Abschnitt einen mit Ausnahme der Oberseite allseitig geschlossenen Raum zur Aufnahme von Betriebsgeräten bilden. Das Gehäuseoberteil ist vorzugsweise aus Kunststoff gefertigt, wobei lichtdichte Bereiche aus Polycarbonat und lichtdurchlässige Bereiche aus Polymethylmethacrylat gefertigt sind und das Gehäuseoberteil mittels 2-Komponenten Spritzgießverfahren hergestellt ist. Diese Kombination ist insbesondere bei der erfindungsgemäßen Fassadenleuchte von Vorteil, weil klares, lichtdurchlässiges Polycarbonat unter Sonneneinstrahlung vergilbt, während The heat sink can form in the middle section a space except for the topside all around closed space for receiving control gear. The upper housing part is preferably made of plastic, wherein light-tight areas of polycarbonate and translucent areas of polymethyl methacrylate are made and the upper housing part is made by means of 2-component injection molding. This combination is particularly advantageous in the façade luminaire according to the invention, because clear, translucent polycarbonate yellowing under sunlight, while
Polymethylmethacrylat hier kaum anfällig ist. Andererseits ist Polymethylmethacrylat nicht gut geeignet, um die nachfolgend beschriebenen Schnappverschlüsse zu realisieren, weil Polymethylmethacrylat spröder und empfindlicher gegen Spannungsrisse als Polycarbonat ist. Polymethyl methacrylate is hardly susceptible here. On the other hand, polymethyl methacrylate is not well suited to realize the snap closures described below because polymethyl methacrylate is more brittle and more susceptible to stress cracking than polycarbonate.
Eine Fassadenleuchte muss in der Regel wetterfest ausgeführt sein, d.h. die Schnittstelle zwischen Gehäuseoberteil und Gehäuseunterteil muss gegen Eindringen von Schmutz und Feuchtigkeit abgedichtet sein. Dazu kann das Gehäuseunterteil einen umlaufenden Steg aufweisen, auf dem eine umlaufende Dichtung angeordnet wird. Wird dann das A façade luminaire must normally be made weatherproof, i. the interface between the upper part of the housing and the lower part of the housing must be sealed against the ingress of dirt and moisture. For this purpose, the lower housing part may have a peripheral web on which a circumferential seal is arranged. Will that be
Gehäuseoberteil mittels einer Schnappverbindung am Gehäuseunterteil befestigt ist, kann das das Gehäuseoberteil gegen die Dichtung gepresst werden, wodurch diese zwischen Housing upper part is fastened by means of a snap connection to the lower housing part, the upper housing part can be pressed against the seal, whereby this between
Gehäuseoberteil und Gehäuseunterteil eingeklemmt ist und so die Dichtheit gewährleistet. Housing upper part and lower housing part is clamped, thus ensuring the tightness.
Bevorzugt kann die Schnappverbindung dadurch realisiert sein, dass das Gehäuseoberteil das Gehäuseunterteil seitlich übergreift oder - im Falle der Verwendung der Luftspalte - in die am Innenumfang des Gehäuseunterteils verlaufenden Luftspalte eingreift, wobei in den seitlichen Bereichen des Gehäuseoberteils, welche beispielsweise laschenartig oder als Seitenwände ausgeführt sein können, Ausnehmungen vorgesehen sind, in die Schnappnasen eingreifen, wenn das Gehäuseunterteil mit dem Gehäuseoberteil verschlossen ist, wobei die Schnappnasen am Gehäuseunterteil angeformt sind. Preferably, the snap connection can be realized in that the upper housing part laterally engages over the lower housing part or - in the case of using the air gaps - engages in the running on the inner circumference of the housing lower part air gaps, wherein in the Recesses are provided in the snap-in lugs engage when the lower housing part is closed with the upper housing part, wherein the snap lugs are integrally formed on the lower housing part.
Es sei darauf hingewiesen, dass diese Art des Verschließens von Gehäuseoberteil mit Gehäuseunterteil nicht beschränkt ist auf den Einsatz bei einer erfindungsgemäßen It should be noted that this type of closing of the upper housing part with lower housing part is not limited to the use in an inventive
Fassadenleuchte, sondern dass dieser Verschluss bei jeder Leuchte eingesetzt werden kann, die gegen Eindringen von Staub, Schmutz und Feuchtigkeit geschützt werden muss. Dieser Verschluss zeichnet sich insbesondere dadurch aus, dass die Leuchte werkzeuglos und rasch verschlossen werden kann, wobei die Dichtheit gewährleistet ist. Beispielsweise kommen bei Fassaden oftmals eine sehr große Anzahl solcher Leuchten zum Einsatz. Somit ist Facade lamp, but that this closure can be used with any luminaire, which must be protected against ingress of dust, dirt and moisture. This closure is characterized in particular by the fact that the lamp can be closed without tools and quickly, the tightness is guaranteed. For example, facades often use a very large number of such luminaires. Thus is
Montagfreundlichkeit für Fassadenbauer bzw. Elektriker bei der Auswahl solcher Leuchten ein wichtiges Kriterium. Insofern betrifft die Erfindung auch eine Leuchte höherer Schutzart mit einem derartigen Verschluss. Easy installation for facade builders or electricians in the selection of such lights an important criterion. In this respect, the invention also relates to a luminaire of higher protection with such a closure.
Nachfolgend soll die Erfindung anhand der beiliegenden Zeichnung näher erläutert werden. Es zeigen: The invention will be explained in more detail with reference to the accompanying drawings. Show it:

Fig. 8 die Unterseite der Fassadenleuchte gemäß Figur 5. In Figur 1 ist eine Explosionsdarstellung eines ersten Ausführungsbeispiels einer erfindungsgemäßen Fassadenleuchte gezeigt. Die Fassadenleuchte weist ein Gehäuse auf, welches aus einem Gehäuseunterteil 3 und einem Gehäuseoberteil 4 besteht. Das 8 shows the underside of the facade light according to FIG. 5. 1 shows an exploded view of a first embodiment of a facade lamp according to the invention is shown. The facade lamp has a housing which consists of a housing lower part 3 and a housing upper part 4. The
Gehäuseunterteil ist in drei Abschnitte AI, A2, A3 unterteilt. In den seitlichen Abschnitten AI und A3 sind jeweils zwei LED-Cluster 1 angeordnet. Ein LED-Cluster 1 wird aus mindestens zwei Leuchtdioden gebildet. Vorzugsweise werden drei Leuchtdioden pro LED- Cluster 1 verwendet und zwar mit den Farben Rot, Grün und Blau; ebenso ist es möglich, zwei vorzugsweise drei weiße Leuchtdioden pro LED-Cluster 1 zu verwenden. In Lichtaustrittsrichtung gesehen vor jedem LED-Cluster 1 ist eine Optik 2 angeordnet. Diese Optik 2 erzeugt eine elliptische Lichtverteilung auf der angestrahlten Fläche. Durch die entsprechende räumliche Platzierung innerhalb der Fassadenleuchte erzeugen die vier LED- Cluster 1 zusammen mit den insgesamt vier Optiken 2 eine Lichtverteilung, die einen breiten Streifen an der zu beleuchtenden Fläche, also in der Regel an einer Fassade oder Wand, erhellt. Eine schmale Bauweise der Fassadenleuchte ist hierbei dadurch gewährleistet, dass die LED-Cluster nebeneinander, insbesondere im Wesentlichen entlang einer Geraden angeordnet sind. Diese Gerade verläuft parallel zur Längserstreckung der elliptischen Lichtverteilung, vorzugsweise mittig durch die Leuchte. Die Leuchtdioden der LED-Cluster 1 sind auf Platinen 5 angebracht bzw. verlötet. Wie in Figur 2 ersichtlich liegen die Platinen 5 mit ihren Rückseiten auf einer Kontaktfläche 8 der Basis 7 des Kühlkörpers auf. Im Ausführungsbeispiel gemäß Figur 1 ist das Gehäuseunterteil 3 gleichzeitig als Kühlkörper ausgeführt. Derart als Kühlkörper ausgeführt, weist das Gehäuseunterteil 3 im Bereich der seitlichen Abschnitte AI und A3 Kühlrippen 6 auf, die an die Basis 7 angeformt sind. Die Kühlrippen 6 verlaufen in Längsrichtung des Housing base is divided into three sections AI, A2, A3. In the lateral sections AI and A3, two LED clusters 1 are arranged in each case. An LED cluster 1 is formed from at least two light-emitting diodes. Preferably, three LEDs per LED cluster 1 are used, namely with the colors red, green and blue; It is also possible to use two preferably three white LEDs per LED cluster 1. Seen in the light exit direction in front of each LED cluster 1, an optical system 2 is arranged. This optic 2 generates an elliptical light distribution on the illuminated surface. Through the corresponding spatial placement within the façade luminaire, the four LED clusters 1, together with the total of four optics 2, produce a light distribution which illuminates a broad strip on the surface to be illuminated, ie as a rule on a facade or wall. A narrow construction of the façade luminaire is ensured by the fact that the LED clusters are arranged side by side, in particular substantially along a straight line. This straight line runs parallel to the longitudinal extension of the elliptical light distribution, preferably centrally through the luminaire. The LEDs of the LED cluster 1 are mounted on boards 5 or soldered. As can be seen in Figure 2, the boards are 5 with their backs on a contact surface 8 of the base 7 of the heat sink. In the embodiment of Figure 1, the lower housing part 3 is simultaneously designed as a heat sink. Thus embodied as a heat sink, the lower housing part 3 in the region of the lateral sections AI and A3 on cooling fins 6, which are integrally formed on the base 7. The cooling fins 6 extend in the longitudinal direction of
Gehäuseunterteils 3. Aus ästhetischen Gründen ist das Gehäuseunterteil von im Wesentlichen geraden und glatten Außenwänden umschlossen. Diese Formgestaltung ist möglich, weil das Gehäuseunterteil 3 als Aludruckgussteil ausgeführt ist. Aber insbesondere dann, wenn eine höhere Kühlleistung bei gleicher Oberfläche gefordert ist, können die stirnseitigen  Housing base 3. For aesthetic reasons, the lower housing part is enclosed by substantially straight and smooth outer walls. This shape design is possible because the lower housing part 3 is designed as an aluminum die cast part. But especially when a higher cooling capacity is required for the same surface, the front-side
Außenwände entfallen, um eine verbesserte Luftzirkulation zu ermöglichen. Gemäß Figur 4 entspricht die Bauhöhe der Kühlrippen 6 mit Basis 7 in etwa der Tiefe des Aufnahmeraums 15. Somit entsteht ein Körper, dessen Außenkonturen einem Quader angenährt sind, bei dem der Innenraum optimal aufgeteilt ist für die unterschiedlichen Nutzungen, nämlich als Raum zur Aufnahme von Platinen 5, LED-Clustern 1 und Optik 2, die alle eine verhältnismäßig geringe Einbautiefe benötigen - vergleiche hierzu Figur 2 - und von Betriebsgeräten und Anschlussklemmen, die eine verhältnismäßig großen Raumbedarf haben. Outer walls omitted to allow for improved air circulation. According to Figure 4 corresponds to the height of the cooling fins 6 with base 7 in about the depth of the receiving space 15. Thus, a body, the outer contours of which are approximated a cuboid, in which the interior is optimally divided for the different uses, namely as a space for receiving Boards 5, LED clusters 1 and 2 optics, all of which require a relatively small installation depth - see Figure 2 - and of operating devices and terminals, which have a relatively large amount of space.
Dementsprechend können im mittleren Abschnitt A2 (nicht dargestellte) Betriebsgeräte, wie beispielsweise LED-Treiber oder Steuereinheiten, wie beispielsweise DMX-Controller sowie (nicht dargestellte) elektrische Anschlussklemmen untergebracht werden. Die elektrische Versorgung erfolgt über handelsübliche Kabelverschraubungen durch die ein (nicht dargestelltes) Kabel hindurchgeführt werden kann und die Gehäuse und Kabel gegeneinander abdichten. Vorzugsweise wird die erfindungsgemäße Fassadenleuchte über eine Accordingly, in the middle section A2 (not shown) operating devices, such as LED drivers or control units, such as DMX controllers and (not shown) electrical terminals are housed. The electrical supply is via standard cable glands through which a (not shown) cable can be passed and the housing and cable seal against each other. Preferably, the facade lamp according to the invention via a
Niederspannungsversorgung mit 24 V oder 48 V versorgt, wobei die Versorgungseinheit, d.h. der LED-Treiber meist außerhalb der Leuchte platziert wird und im dafür vorgesehenen Raum meist nur die Steuereinheit samt (nicht dargestellten) Anschlussklemmen angeordnet wird. Supplied with 24 V or 48 V low voltage supply, the supply unit, i. the LED driver is usually placed outside the luminaire and in the designated space usually only the control unit together with (not shown) terminals is arranged.
Der Aufnahmeraum 15 sowie die beiden seitlichen Abschnitte AI und A3 sind zur Oberseite hin mit einem umlaufenden Steg 10 abgeschlossen. Dieser Steg 10 nimmt eine umlaufende Dichtung 11 auf, wobei das Profil dieser Dichtung - wie in Figur 2 ersichtlich - der Kontur des Steges 11 angepasst ist. Ebenfalls in Figur 2 ist ersichtlich, dass die Dichtung 11 in eine umlaufende Nut 16 des Gehäuseoberteils 4 eingreift. Im zusammengebauten Zustand von Gehäuseoberteil 4 und Gehäuseunterteil 3 pressen diese beiden Gehäuseteile die Dichtung gegeneinander, um so eine sichere Abdichtung gegen Staub, Schmutz, und Feuchtigkeit zu gewährleisten. The receiving space 15 and the two lateral sections AI and A3 are closed to the top with a circumferential ridge 10. This web 10 receives a circumferential seal 11, wherein the profile of this seal - as shown in Figure 2 - the contour of the web 11 is adjusted. It can also be seen in FIG. 2 that the seal 11 engages in a circumferential groove 16 of the housing upper part 4. In the assembled state of the upper housing part 4 and the lower housing part 3, these two housing parts press the seal against each other, so as to ensure a secure seal against dust, dirt, and moisture.
Das Gehäuseoberteil 4 ist gebildet aus einem lichtundurchlässigen Teil, das bevorzugt aus Polycarbonat hergestellt ist und im vorliegenden Ausführungsbeispiel aus vier kreisrund ausgeführten lichtdurchlässigen, glasklaren Abdeckelementen 9, die bevorzugt aus The upper housing part 4 is formed from an opaque part, which is preferably made of polycarbonate and in the present embodiment of four circular translucent, glass-clear cover elements 9, preferably made of
Polymethylmethacrylat gefertigt sind. Die Herstellung des Gehäuseoberteils 4 kann mittels 2K-Spritzgießen erfolgen. In Figur 3 ist eine Frontansicht des Ausführungsbeispiels gemäß Figur 1 gezeigt. Das Polymethyl methacrylate are made. The production of the upper housing part 4 can be done by means of 2K injection molding. FIG. 3 shows a front view of the exemplary embodiment according to FIG. The
Gehäuseoberteil 4 übergreift das Gehäuseunterteil 3 mit laschenartig ausgebildeten Upper housing part 4 engages over the lower housing part 3 with tab-like design
Seitenwänden 14, wobei in den Seitenwänden Ausnehmungen 17 vorgesehen sind, die mit Schnappnasen 12 zusammenwirken und den Schnappverschluss zwischen Gehäuseoberteil 4 und Gehäuseunterteil 3 bilden. Konkret sind auf einer Seite des Gehäuseunterteils 3 insgesamt neun Schnappnasen 12 über die laschenartige Seitenwand verteilt angeordnet. Side walls 14, wherein recesses 17 are provided in the side walls, which cooperate with snap lugs 12 and the snap lock between the upper housing part 4 and lower housing part 3 form. Specifically, a total of nine snap tabs 12 are distributed over the tab-like side wall on one side of the housing base 3.
Ein zweites Ausführungsbeispiel einer erfindungsgemäßen Fassadenleuchte ist in den Figuren 5 bis 8 dargestellt, wobei gleiche Elemente mit den gleichen Bezugszeichen versehen sind. Hinsichtlich der Aufteilung des Gehäuses in seitliche Abschnitte AI und A3 zur Anordnung der LED-Cluster 1 sowie einem Abschnitt A2 zur Aufnahme der Betriebsgeräte und weiteren Komponenten gleich dieses zweite Ausführungsbeispiel dem Beispiel der Figuren 1 bis 4. Auch die Mittel zur Beeinflussung der Lichtabgabe sind hier identisch, weshalb nachfolgend in erster Linie die Unterschiede erläutert werden sollen. Ein wesentlicher Unterschied bei diesem zweiten Ausführungsbeispiel besteht dabei darin, dass das Abführen der während des LED-Betriebs auftreten Wärme in erster Linie mit Hilfe von Luftschlitzen 20 erfolgt, welche in der Umgebung der LED-Cluster 1 im Gehäuse ausgebildet sind. Insbesondere sind diese Luftschlitze 20 am Innenumfang der Wand des Gehäuseunterteils 3 ausgebildet, was durch eine entsprechende - zumindest teilweise - doppelwandige Ausführung der Gehäusewand erzielt wird. In diesem Fall übergreift dann das Gehäuseoberteil 4 das Gehäuseunterteil 3 nicht mehr vollständig sondern ist stattdessen derart ausgebildet, dass die Seitenwand 14 mit den Laschen in den bzw. die Luftschlitze 20 eingreift und mit hier befindlichen Schnappnasen zusammenwirkt. Lediglich im mittleren Bereich A2 im Bereich der Kabelverschraubungen 13 ist das Gehäuseunterteil 3 nicht doppelwandig ausgebildet, so dass hier eine Lasche das Gehäuseunterteil 3 übergreift. Die Breite der Luftschlitze 20 ist dabei derart bemessen, dass trotz Eingreifen der Seitenwand 14 genügend Freiraum verbleibt, der ein Durchströmen mit Luft und dementsprechend eine effektives Abführen der Wärme ermöglicht. Der am Gehäuseunterteil 3 befindliche Steg 10 zur A second embodiment of a facade light according to the invention is shown in Figures 5 to 8, wherein like elements are provided with the same reference numerals. With regard to the division of the housing into lateral sections AI and A3 for the arrangement of the LED cluster 1 and a section A2 for receiving the operating devices and other components same this second embodiment of the example of Figures 1 to 4. The means for influencing the light output are here identical, which is why primarily the differences should be explained below. An essential difference in this second embodiment consists in the fact that the removal of the heat occurring during the LED operation takes place primarily with the aid of air slots 20, which are formed in the environment of the LED cluster 1 in the housing. In particular, these louvers 20 are formed on the inner circumference of the wall of the lower housing part 3, which is achieved by a corresponding - at least partially - double-walled design of the housing wall. In this case, the upper housing part 4 then no longer completely overlaps the housing lower part 3, but instead is configured such that the side wall 14 engages with the tabs in the air slot (s) 20 and interacts with snap-action lugs located here. Only in the central region A2 in the region of the cable glands 13, the lower housing part 3 is not double-walled, so that here a tab engages over the lower housing part 3. The width of the louvers 20 is dimensioned such that, despite engagement of the side wall 14 remains sufficient clearance, which allows a passage of air and accordingly an effective dissipation of heat. The located on the lower housing part 3 web 10 for
Aufnahme der Dichtung 11 ist in diesem Fall leicht nach innen versetzt an der Innenseite der Luftschlitze 20 ausgebildet, so dass nach wie vor die erforderliche zuverlässige Abdichtung der Leuchte erzielt wird. Receiving the seal 11 is in this case slightly offset inwardly formed on the inside of the louvers 20, so that still the required reliable sealing of the lamp is achieved.
Wie dementsprechend insbesondere der Aufsicht von Figur 7 entnommen werden kann, sind jeweils an den beiden Längsseiten des Gehäuses im Bereich der seitlichen Abschnitte AI und A3 zur Aufnahme der LED-Cluster 1 Luftschlitze 20 ausgebildet, durch welche ein sehr effektives Abführen der Wärme erzielt wird. Es hat sich gezeigt, dass die Wirkung dieser Luftschlitze 20 sogar derart effektiv ist, dass keine weiteren Maßnahmen zur Kühlung erforderlich wären. Dementsprechend kann bei diesem Ausführungsbeispiel auch auf die unterhalb der LED-Cluster 1 angeordneten Kühlrippen 6, wie sie bei dem Beispiel der Figuren 1 bis 4 vorgesehen sind, verzichtet werden. Stattdessen ist bei dieser Variante lediglich vorgesehen, dass in diesen Bereichen an der Unterseite des Gehäuseunterteils 3 im Wesentlichen quadratische Vertiefungen 21 ausgebildet sind. Die Herstellung des wiederum vorzugsweise als Aluminiumdruckgußteil ausgebildeten Gehäuseunterteils 3 wird hierdurch vereinfacht. Selbstverständlich wäre es allerdings zur Erhöhung der Kühlleistung denkbar, auch bei diesem zweiten Ausführungsbeispiel zusätzliche Kühlrippen auszubilden, sofern dies aufgrund der Umgebungseinflüsse sinnvoll erscheint. Bezugszeichenliste:Accordingly, as can be seen in particular from the plan view of FIG. 7, louvers 20 are respectively formed on the two longitudinal sides of the housing in the region of the lateral sections AI and A3 for receiving the LED cluster 1, by means of which a very effective dissipation of the heat is achieved. It has been found that the effect of these louvers 20 is even so effective that no further measures for cooling would be required. Accordingly, in this embodiment, on the below the LED cluster 1 arranged cooling fins 6, as provided in the example of Figures 1 to 4, are dispensed with. Instead, it is merely provided in this variant that substantially square depressions 21 are formed in these areas on the underside of the housing lower part 3. The preparation of the turn, preferably designed as Aluminiumdruckgußteil housing lower part 3 is thereby simplified. Of course, it would be conceivable, however, to increase the cooling capacity, even in this second embodiment form additional cooling fins, if this seems reasonable due to the environmental influences.
