Die vorliegende Erfindung betrifft allgemein eine Leuchte und insbesondere eine Wand- und/oder Deckenleuchte mit zumindest einem Leuchtmittel vorzugsweise in Form einer LED, dem eine Reflektoranordnung mit zumindest einem Reflektor zum Umlenkung des vom Leuchtmittel abgegebenen Lichts zugeordnet ist.The present invention generally relates to a luminaire and in particular to a wall and / or ceiling luminaire with at least one luminous means, preferably in the form of an LED, which is assigned a reflector arrangement with at least one reflector for deflecting the light emitted by the luminous means.

Wand- und Deckenleuchten, die als Aufputzlampe montiert oder in Wand- und/oder Deckenpaneele integriert, beispielsweise in Paneelausnehmungen versenkt sein können oder auch als Bodenleuchte im Boden versenkt sein können, unterliegen regelmäßig einer Vielzahl verschiedener, oftmals gegenläufiger Anordnungen. Während einerseits immer kleinere Baugrößen gefordert werden, soll andererseits dennoch eine hohe Leuchtkraft mit gleichmäßiger Raumausleuchtung erreicht werden. Dabei ist nicht nur die geringe Baugröße an sich problematisch und mit der geforderten Raumausleuchtung schwer in Einklang zu bringen, sondern auch die damit einhergehenden thermischen Probleme sind schwierig zu lösen. Bei kleinen Abmessungen sitzt das Leuchtmittel in geringem Abstand sehr nahe an den angrenzenden Korpusflächen, zum anderen steht insgesamt wenig Korpusfläche zur Ableitung der entstehenden Wärme zur Verfügung. Zum anderen entstehen bei klein bauenden, punktförmigen Lichtquellen mit hoher Leuchtkraft oftmals eine Blendwirkung und eine als unangenehm empfundene Lichtverteilung.Wall and ceiling lights that are mounted as surface-mounted or integrated in wall and / or ceiling panels, for example, can be recessed in Paneelausnehmungen or sunk as floor light in the ground, are regularly subject to a variety of different, often opposing arrangements. While on the one hand ever smaller sizes are required, on the other hand, a high luminosity with uniform room illumination should still be achieved. Not only is the small size itself difficult to reconcile with the required room lighting, but also the associated thermal problems are difficult to solve. In the case of small dimensions, the illuminant sits very close to the adjoining corpus surfaces at a small distance; on the other hand, there is a small amount of body area available for dissipating the heat generated. On the other hand arise at small-sized, point-shaped light sources with high luminosity often a dazzling effect and perceived as unpleasant light distribution.

Hiervon ausgehend liegt der vorliegenden Erfindung die Aufgabe zugrunde, eine verbesserte Leuchte zu schaffen, die Nachteile des Standes der Technik vermeidet und Letzteren in vorteilhafter Weise weiterbildet. Insbesondere soll eine klein bauende, einfach zu fertigende Wand- und/oder Deckenleuchte geschaffen werden, die mit einem hohen Leuchtenbetriebswirkungsgrad an einem vorgesehenen Zielbereich eine hohe Lichtmenge erzeugen kann.Proceeding from this, the present invention seeks to provide an improved luminaire, which avoids the disadvantages of the prior art and the latter develops in an advantageous manner. In particular, a small-sized, easy-to-produce wall and / or ceiling light is to be created, which can generate a high amount of light with a high luminaire operating efficiency at a designated target area.

Erfindungsgemäß wird diese Aufgabe durch eine Leuchte gemäß Anspruch 1 gelöst. Bevorzugte Ausgestaltungen der Erfindung sind Gegenstand der abhängigen Ansprüche.According to the invention this object is achieved by a luminaire according to claim 1. Preferred embodiments of the invention are the subject of the dependent claims.

Um besonders klein bauen zu können, wird vorgeschlagen, das zumindest eine Leuchtmittel unmittelbar auf einer Leiterplatine anzuordnen, mittels derer das genannte Leuchtmittel angesteuert und/oder mit Energie versorgt wird. Hierdurch kann nicht nur besonders kompakt gebaut werden, sondern es wird auch eine gute Wärmeabführung erreicht, da ein Teil der vom Leuchtmittel erzeugten Wärme direkt über die Leiterplatine flächig abgeleitet werden kann.In order to be able to build very small, it is proposed to arrange the at least one light source directly on a printed circuit board, by means of which the said light source is driven and / or supplied with energy. As a result, not only can be built very compact, but it is also a good heat dissipation achieved because part of the heat generated by the lamp can be derived directly across the circuit board area.

Insbesondere von Vorteil ist die Verwendung einer Leiterplatine dann, wenn eine Mehrzahl von Leuchtmitteln vorgesehen sind. In diesem Fall ergeben sich besondere Vorteile hinsichtlich der Versorgung der Leuchtmittel auch dann, wenn die genannten Leuchtmittel nicht unmittelbar auf der Leiterplatine sitzen. Die sonst notwendigen, umfangreichen Anschlusskabel können entfallen bzw. sind diese in die Leiterplatine integriert, so dass auch bei einer Vielzahl von Leuchtmitteln eine kompakte Anordnung erreicht werden kann.Particularly advantageous is the use of a printed circuit board when a plurality of lighting means are provided. In this case, there are special advantages in terms of the supply of the lamps even if the aforementioned bulbs do not sit directly on the circuit board. The otherwise necessary, extensive connection cable can be omitted or they are integrated into the printed circuit board, so that even with a variety of bulbs, a compact arrangement can be achieved.

Sind eine Vielzahl von Leuchtmitteln vorgesehen, können grundsätzlich verschiedene Anordnungen der Leuchtmittel auf der Leiterplatte vorgesehen sein, beispielsweise eine gestaffelte, matritzenförmige Anordnung der Leuchtmittel. Eine besonders vorteilhafte Ausführung der Erfindung kann dabei darin bestehen, dass die Leuchtmittel voneinander beabstandet in Reihe nebeneinander angeordnet sind. Hierdurch lässt sich insbesondere eine klein bauende Wand- und/oder Deckenleuchte mit schlitzförmigem Lichtaustritt ausbilden. Hierbei kann es vorteilhaft sein, wenn die Leiterplatine eine lang gestreckte, insgesamt schlanke Kontur besitzt, beispielsweise in Form eines Rechtecks.If a multiplicity of illuminants are provided, fundamentally different arrangements of the illuminants can be provided on the circuit board, for example a staggered, matrix-shaped arrangement of the illuminants. A Particularly advantageous embodiment of the invention may be that the bulbs are spaced from each other in a row next to each other. This makes it possible in particular to form a small-wall and / or ceiling lamp with slit-shaped light exit. It may be advantageous if the circuit board has an elongated, generally slim contour, for example in the form of a rectangle.

Die einer gemeinsamen Leiterplatine zugeordneten Leuchtmittel können grundsätzlich unterschiedlich ausgebildet sein. Die verschiedene Ausbildung der Leuchtmittel kann dabei in verschiedenen Lichtfarben, verschiedenen Leistungen und/oder verschiedenen Leuchtmittelgeometrien bestehen, wobei vorzugsweise punktförmige, aber auch linienförmige Leuchtmittel Verwendung finden können. Insbesondere sind Leuchtdioden (LEDs) vorgesehen. In vorteilhafter Weiterbildung der Erfindung können jedoch auch mehrere gleichartig ausgebildete Leuchtmittel auf einer gemeinsamen Leiterplatine angeordnet sein.The light sources associated with a common printed circuit board can in principle be designed differently. The different design of the lighting means may consist of different light colors, different powers and / or different illuminant geometries, preferably punctiform, but also linear bulbs can be used. In particular, light-emitting diodes (LEDs) are provided. In an advantageous embodiment of the invention, however, a plurality of identically designed lighting means may be arranged on a common printed circuit board.

Um eine gute Wärmeabfuhr zu erreichen, insbesondere auch bei dichter Anordnung der Leuchtmittel, kann in vorteilhafter Weise eine Metallkernplatine als Leiterplatine Verwendung finden. Insbesondere in Verbindung mit der direkten Befestigung des Leuchtmittels auf der Leiterplatine kann deren Metallkern in besonders effizienter Weise die entstehende Wärme abführen, wobei dies einerseits die Wärme sein kann, die direkt von dem Leuchtmittel in die Leiterplatine gelangt, jedoch andererseits auch die Wärme umfassen kann, die in Form von Lichtstrahlen beispielsweise durch Streuung und/oder Reflexion auf die Leiterplatinenoberfläche einwirkt.In order to achieve a good heat dissipation, especially in dense arrangement of the bulbs, can advantageously be found as a printed circuit board using a metal core board. In particular, in connection with the direct attachment of the light source on the printed circuit board whose metal core can dissipate the heat generated in a particularly efficient manner, on the one hand can be the heat that passes directly from the light source in the circuit board, but on the other hand may include the heat, which acts in the form of light rays, for example by scattering and / or reflection on the printed circuit board surface.

Um die thermischen Belastungen noch besser abzufangen, kann in bevorzugter Weiterbildung der Erfindung zumindest ein Kühlkörper vorgesehen sein, der vorteilhafterweise Kühlrippen zur Vergrößerung der Konvektionsfläche aufweist und der Leiterplatine und/oder dem zumindest einen Reflektor der Reflektoranordnung zugeordnet ist. Insbesondere kann der genannte Kühlkörper mit der Rückseite der Leiterplatine und/oder der Rückseite des zumindest einen Reflektors verbunden sein, so dass ein Wärmeübergang von der Leiterplatine und/oder dem Reflektor auf den Kühlkörper erfolgen und von dessen Kühlrippen abgegeben werden kann.In order to better absorb the thermal loads, in a preferred embodiment of the invention, at least one heat sink may be provided, which advantageously has cooling ribs for enlarging the convection surface and is associated with the printed circuit board and / or the at least one reflector of the reflector arrangement. In particular, the said heat sink can be connected to the rear side of the printed circuit board and / or the rear side of the at least one reflector be, so that a heat transfer from the printed circuit board and / or the reflector made on the heat sink and can be discharged from the cooling fins.

Zur Erzielung eines guten Wärmeübergangs auf den genannten Kühlkörper sind in vorteilhafter Weiterbildung der Erfindung die Leiterplatine und der Kühlkörper bzw. der zumindest eine Reflektor und der Kühlkörper aneinander formangepasst, vorteilhafterweise derart, dass ein vollflächiges Anliegen des Kühlkörpers an der Leiterplatinenrückseite und/oder an der Reflektorrückseite vorgesehen ist. Der Kühlkörper kann hierzu entsprechende Anschlussflächen besitzen, die an die Rückseite der Leiterplatine und/oder die Rückseite des Reflektors formangepasst sind. Vorteilhafterweise ist der zumindest eine Kühlkörper dabei derart beschaffen, dass im Wesentlichen die gesamte Rückseite der Leiterplatine und die gesamte Rückseite des zumindest einen Reflektors von dem Kühlkörper abgedeckt ist. Der Kühlkörper und der Reflektor können hierbei als separate Bauteile ausgebildet und in der genannten Weisen aneinander formangepasst sein. Alternativ hierzu kann aber auch vorgesehen sein, dass der Reflektor in Form einer Beschichtung unmittelbar auf dem Kühlkörper aufgebracht wird, so dass sozusagen die entsprechende Kühlkörperoberfläche selbst als Reflektor arbeitet.To achieve a good heat transfer to said heat sink, the printed circuit board and the heat sink or the at least one reflector and the heat sink are adapted to one another in an advantageous development of the invention, advantageously such that a full-surface concerns of the heat sink on the printed circuit board back side and / or on the reflector back is provided. For this purpose, the heat sink may have corresponding connection surfaces which are adapted to the back side of the printed circuit board and / or the rear side of the reflector. Advantageously, the at least one heat sink is designed in such a way that essentially the entire rear side of the printed circuit board and the entire rear side of the at least one reflector are covered by the heat sink. The heat sink and the reflector can in this case be formed as separate components and be adapted to one another in the aforementioned ways. Alternatively, however, it can also be provided that the reflector in the form of a coating is applied directly to the heat sink, so that, so to speak, the corresponding heat sink surface itself operates as a reflector.

Die genannte Leiterplatine kann an dem Kühlkörper grundsätzlich in verschiedener Art und Weise befestigt sein. Um einen guten Wärmeübergang zu erzielen, wird die Leiterplatine vorteilhafterweise kraftschlüssig gegen die entsprechende Kühlkörperoberfläche gedrückt und/oder mit dieser formschlüssig verbunden. Eine bevorzugte Ausführung kann hierbei darin bestehen, dass die Leiterplatine in einer Kühltasche sitzt, in der die genannte Leiterplatine von ihrer Rückseite her an gegenüber liegenden Rändern vom Kühlkörper umgriffen ist, wobei vorteilhafterweise separate Kühlkörperteile vorgesehen sind, die gegeneinander und/oder auf die genannte Leiterplatine spannbar sind. Nach einer vorteilhaften Ausführung der Erfindung können dem zumindest einen Reflektor und der Leiterplatine separate Kühlkörperteile zugeordnet sein, die miteinander verbunden werden können, vorteilhafterweise derart, dass die Leiterplatine mit ihrer Rückseite an eine zwischen den Kühlkörperteilen gebildeten Kühltasche gespannt wird.Said printed circuit board can be attached to the heat sink in principle in various ways. In order to achieve a good heat transfer, the printed circuit board is advantageously pressed non-positively against the corresponding heat sink surface and / or connected to this form-fitting manner. A preferred embodiment may be that the printed circuit board is seated in a cooling pocket in which said printed circuit board is encompassed by the heat sink at its opposite rear edges, wherein advantageously separate cooling body parts are provided, which against each other and / or on said printed circuit board are tensionable. According to an advantageous embodiment of the invention may be associated with the at least one reflector and the printed circuit board separate heat sink parts that can be interconnected, advantageously such that the printed circuit board is stretched with its back to a cooling pocket formed between the cooling body parts.

Hinsichtlich Formgebung kann die Lampe natürlich grundsätzlich verschiedene Gestaltungen besitzen. Um jedoch eine einfache und kostengünstige Fertigung bei gleichzeitig hoher Variabilität hinsichtlich der Außenmaße der Lampe zu ermöglichen, kann in bevorzugter Weiterbildung der Erfindung vorgesehen sein, dass der Leuchtenkorpus einschießlich zumindest des Reflektors als Endlos-Strangprofil ausgebildet ist, so dass er auf eine gewünschte Länge abgelängt werden kann. Insbesondere können auch die Leiterplatine und der zumindest eine Kühlkörper jeweils als Endlos-Strangprofil ausgebildet sein, so dass auch diese Komponenten der Lampe auf die jeweils gewünschte Lampenlänge abgelängt werden können. Vorzugsweise besitzt dabei der Kühlkörper stegförmig ausgebildete Kühlrippen, die sich parallel zur Längsrichtung des Strangprofiles erstrecken. Hierdurch können insbesondere bei Herstellung mittel Strangprofilextrusion oder Strangguss sehr fein ausgebildete Rippen vorgesehen werden, die auch bei sehr kleiner Baugröße der gesamten Lampe eine große Wärmeübergangsfläche bereitstellen.Of course, with regard to shaping, the lamp can basically have different designs. However, in order to enable a simple and cost-effective production with high variability in terms of the external dimensions of the lamp, can be provided in a preferred embodiment of the invention that the lamp body einschießlich at least the reflector is designed as an endless extruded profile, so that it is cut to a desired length can be. In particular, the printed circuit board and the at least one heat sink can each be designed as an endless extruded profile, so that these components of the lamp can be cut to the respective desired lamp length. Preferably, the heat sink has web-shaped cooling ribs which extend parallel to the longitudinal direction of the extruded profile. As a result, very finely formed ribs can be provided, in particular when producing medium extruded profile extrusion or continuous casting, which provide a large heat transfer surface even with a very small overall size of the entire lamp.

Um eine vom menschlichen Auge als angenehm empfundene Raumausleuchtung zu erreichen und auch bei hohen Lichtstärken eine Blendwirkung zu vermeiden, ist in Weiterbildung der Erfindung vorgesehen, dass das zumindest eine Leuchtmittel abgeblendet angeordnet ist. Das Leuchtmittel wird dabei von Korpuskonturen derart verdeckt, dass eine direkte, gerade Sichtachse in das Leuchtmittel unterbunden ist. Insbesondere kann hierbei die Reflektoranordnung derart ausgebildet sein, dass die genannte Sichtachse auf das zumindest eine Leuchtmittel verdeckt ist. Das von dem Leuchtmittel erzeugte Licht tritt also nicht direkt in den auszuleuchtenden Raum aus, sondern wird zumindest einmal über eine der Reflektorflächen geleitet, so dass kein primäres Licht abgestrahlt wird, sondern von der Lampe nur sekundäres, terziäres oder mehrfach reflektiertes Licht in den Raum abgegeben wird. Neben der Blendfreiheit kann hierdurch eine gleichmäßige, atmosphärisch bevorzugte Lichtausbreitung erreicht werden. Vorteilhafterweise ist dabei die Reflektoranordnung derart ausgebildet und/oder derart auf die Ausbildung des Leuchtmittels abgestimmt, dass das von dem Leuchtmittel abgegebene Licht im Wesentlichen vollständig auf Reflektorflächen trifft und von diesen nahezu vollständig in den auszuleuchtenden Bereich gelenkt wird.In order to achieve a perceived by the human eye as pleasant room illumination and to avoid glare even at high light levels, is provided in a further development of the invention that the at least one light source is arranged dimmed. The light source is concealed by Korpuskonturen so that a direct, straight line of sight is prevented in the bulb. In particular, in this case, the reflector assembly may be formed such that said visual axis is concealed on the at least one light source. Thus, the light generated by the light source does not pass directly into the space to be illuminated, but is conducted at least once over one of the reflector surfaces, so that no primary light is emitted, but only secondary, terziäres or multiply reflected light emitted from the lamp into the room becomes. In addition to the glare-free a uniform, atmospheric preferred light propagation can be achieved. In this case, the reflector arrangement is advantageously designed and / or adapted to the design of the luminous means such that the light emitted by the luminous means is substantially complete meets reflector surfaces and is directed by these almost completely into the area to be illuminated.

Um einen hohen Leuchtenbetriebswirkungsgrad sowie eine hohe Lichtmenge am vorgegebenen Ziel zu erreichen, kann dabei vorgesehen sein, dass die Reflektoranordnung beidseitig des zumindest einen Leuchmittels an die Leiterplatine angrenzt und Reflektorflächenkanten einen schlitzförmigen Lichtaustrittsquerschnitt der Lampe begrenzen. Die sich beidseitig des Leuchtmittels erstreckende Reflektoranordnung fängt das vom Leuchtmittel abgegebene Licht nahezu vollständig ein und wirft dieses in der gewünschten Richtung mit einem gewünschten Strahlengang in den vorgegebenen Zielbereich. Vorteilhafterweise grenzt dabei die Reflektoranordnung im Wesentlichen unmittelbar an die das zumindest eine Leuchtmittel tragende Leiterplatinenvorderseite, so dass auch im Wesentlichen parallel zur Leiterplatine vom Leuchtmittel abgegebenes Licht vom Reflektor eingefangen wird. Das Leuchtmittel ist dabei sozusagen von der Reflektoranordnung und der Leiterplatine eingeschlossen.In order to achieve a high luminaire operating efficiency and a high amount of light at the predetermined target, it can be provided that the reflector arrangement adjoins the printed circuit board on both sides of the at least one luminous means and reflector surface edges delimit a slot-shaped light exit cross section of the lamp. The reflector arrangement extending on both sides of the luminous means almost completely intercepts the light emitted by the luminous means and throws it in the desired direction in the desired direction with a desired beam path. Advantageously, the reflector arrangement essentially adjoins directly the printed circuit board front side carrying the at least one luminous means, so that light emitted by the luminous means substantially parallel to the printed circuit board is captured by the reflector. The lamp is as it were enclosed by the reflector assembly and the circuit board.

Vorteilhafterweise umfasst die Reflektoranordnung einen ersten Reflektor, der vom auszuleuchtenden Raum aus betrachtet hinter dem zumindest einen Leuchtmittel angeordnet ist, sowie einen zweiten Reflektor, der von dem auszuleuchtenden Raum aus betrachtet vor dem zumindest einen Leuchtmittel angeordnet und vorteilhafterweise derart ausgebildet ist, dass von dem Leuchtmittel auf den zweiten Reflektor fallendes Licht von dem genannten zweiten Reflektor auf den ersten Reflektor gelenkt wird.Advantageously, the reflector arrangement comprises a first reflector which is arranged behind the at least one luminous means when viewed from the room to be illuminated, and a second reflector which, viewed from the space to be illuminated, is arranged in front of the at least one luminous means and is advantageously designed such that the luminous means incident on the second reflector light from the said second reflector is directed to the first reflector.

Die genannten beiden Reflektoren bzw. Reflektorteile oder Reflektorteilflächen können hierbei grundsätzlich verschieden ausgebildet sein, wobei vorteilhafterweise die genannten Reflektoren hinsichtlich Anordnung und Ausbildung voneinander unterschiedlich ausgebildet sind. Insbesondere kann der erste Reflektor von dem Leuchtmittel weiter beabstandet sein als der zweite Reflektor, wobei der entsprechende Abstand des ersten Reflektors ein Vielfaches des Abstandes des zweiten Reflektors betragen kann. Eine vorteilhafte Ausführung kann hierbei darin bestehen, dass der genannte zweite Reflektor, der das Leuchtmittel zum auszuleuchtenden Raum hin verdeckt bzw. abblendet, unmittelbar an das zumindest eine Leuchtmittel angrenzend vor dem genannten Leuchtmittel angeordnet ist. Hierdurch liegt der von dem genannten zweiten Reflektor reflektierte Bildpunkt des Leuchtmittels sehr nahe an dem entsprechenden unreflektierten Bildpunkt, so dass eine homogene, zielgerichtete Ausleuchtung des Zielbereiches erreicht wird.The said two reflectors or reflector parts or reflector partial surfaces can in principle be designed differently, wherein advantageously said reflectors with respect to arrangement and training are formed differently from each other. In particular, the first reflector may be spaced further from the luminous means than the second reflector, wherein the corresponding distance of the first reflector may be a multiple of the distance of the second reflector. An advantageous embodiment may consist in this, in that the said second reflector, which obscures or blocks off the illuminant for the space to be illuminated, is arranged directly adjacent to the at least one luminous means in front of said illuminant. As a result, the pixel of the luminous means reflected by the second reflector is very close to the corresponding unreflected pixel, so that a homogeneous, targeted illumination of the target area is achieved.

Der zweite Reflektor, der unmittelbar vor dem zumindest einen Leuchtmittel sitzt, ist dabei vorteilhafterweise höchstens schwach gekrümmt, wobei er vorteilhafterweise eben ausgebildet sein kann.The second reflector, which sits directly in front of the at least one light source, is advantageously at most slightly curved, wherein it may advantageously be flat.

Der vom auszuleuchtenden Raum aus betrachtet hintere, erste Reflektor kann hinsichtlich seiner Form verschieden ausgebildet sein. In bevorzugter Ausführung der Erfindung kann der erste Reflektor einen rinnenförmige, konkave Krümmung besitzen, wobei vorteilhafterweise der Krümmungsradius mit zunehmendem Abstand von der Leiterplatine und/oder dem Leuchtmittel zunehmen kann.The rear, first reflector, viewed from the room to be illuminated, may have different shapes with respect to its shape. In a preferred embodiment of the invention, the first reflector may have a groove-shaped, concave curvature, wherein advantageously the radius of curvature may increase with increasing distance from the printed circuit board and / or the lighting means.

Um ein Verschmutzen oder gar eine Beschädigung des Leuchtmittels und auch ein Verschmutzen des vor das zumindest eine Leuchtmittel geblendeten Reflektorteils zu verhindern, kann in Weiterbildung der Erfindung eine Schutzverglasung vorgesehen sein, die das zumindest eine Leuchmittel zum Lichtaustrittsquerschnitt hin abdeckt. Die Schutzverglasung kann hierbei zusammen mit der Leiterplatine einen staubdichten Hohlraum begrenzen, in dem das Leuchtmittel angeordnet ist. Da bei üblicher Ausrichtung der Wand- und/oder Deckenleuchte der vor das Leuchtmittel geblendete Reflektorteil einen Staub und/oder Schmutz einfangende Ausrichtung besitzt, kann es hierbei vorteilhaft sein, die Schutzverglasung auch über den genannten zweiten Reflektor zu ziehen, so dass die Schutzverglasung, die Leiterplatine und der genannte zweite Reflektor den zuvor genannten Hohlraum begrenzen. Die Schutzverglasung ist hierbei vorteilhafterweise staubdicht an die angrenzenden Teile angeschlossen, um den abgedeckten Hohlraum staub- und/oder schmutzdicht zu verschließen. Die Schutzverglasung ist hierbei vorteilhafterweise derart geformt, dass sie bei üblicher Ausrichtung der Lampe eine zum offenen Lichtaustrittsquerschnitt hin abfallende Ausrichtung einnimmt.In order to prevent fouling or even damage to the luminous means and also fouling of the reflector part which is blinded by the at least one luminous means, a protective glazing may be provided in the development of the invention which covers the at least one luminous means for the light exit cross section. The protective glazing can in this case limit together with the printed circuit board a dust-tight cavity in which the light source is arranged. Since, in the usual orientation of the wall and / or ceiling light, the reflector part blinded in front of the illuminant has a dust and / or dirt trapping orientation, it may be advantageous to pull the protective glazing over the said second reflector, so that the protective glazing, the PCB and said second reflector to limit the aforementioned cavity. The protective glazing is in this case advantageously dustproof connected to the adjacent parts to dustproof and / or dirt-tight to close the covered cavity. The protective glazing is advantageously shaped in this case, that it assumes a downward sloping to the open light exit cross-section with the usual orientation of the lamp.

Die Schutzverglasung ist hiebei vorteilhafterweise transparent ausgebildet, um den Leuchtenbetriebswirkungsgrad nicht zu beeinträchtigen. Da trotzdem durch das vorgeblendete Schutzglas eine gewisse Streuung und/oder Reflexion zurück zum Leuchtmittel bzw. zur Leiterplatine erfolgt, ist vorteilhafterweise vorgesehen, dass die Leiterplatine auf ihrer der Reflektoranordnung zugewandten Vorderseite mit einer zumindest teilweise reflektierenden Oberfläche vorzugsweise in Form einer weißen Oberflächenbeschichtung versehen ist. Hierdurch wird der von der Schutzverglasung zurück gelenkte Lichtteil von der Leiterplatinenoberfläche wiederum zurück reflektiert und auf die Reflektoranordnung gelenkt, die diesen Lichtteil dann in der gewünschten Richtung in den auszuleuchtenden Bereich wirft.The protective glazing is hiebei advantageously transparent designed so as not to affect the luminaire efficiency. Nevertheless, since some scattering and / or reflection takes place back to the luminous means or the printed circuit board due to the prefaced protective glass, it is advantageously provided that the printed circuit board is provided with an at least partially reflecting surface, preferably in the form of a white surface coating, on its front side facing the reflector arrangement. As a result, the part of the light directed back from the protective glazing is again reflected back from the printed circuit board surface and directed to the reflector arrangement, which then throws this light part in the desired direction into the area to be illuminated.

Die Schutzverglasung kann in Weiterbildung der Erfindung an ihren Rändern an den zuvor genannten zumindest einen Kühlkörper angeschlossen sein, so dass thermische Belastungen der Schutzverglasung reduziert werden, indem Wärme von der Schutzverglasung auf den Kühlkörper übertragen und von diesem abgeleitet wird.The protective glazing can be connected in a further development of the invention at its edges to the aforementioned at least one heat sink, so that thermal stresses on the protective glazing can be reduced by heat is transferred from the protective glazing on the heat sink and derived from this.

Die Erfindung wird nachfolgend anhand eines bevorzugten Ausführungsbeispiels und zugehöriger Zeichnungen näher erläutert. In den Zeichnungen zeigen:

eine Draufsicht auf die Leiterplatine aus Fig. 1, die die Anordnung der Leuchtmittel auf dieser Leiterplatine zeigt.
The invention will be explained in more detail below with reference to a preferred embodiment and associated drawings. In the drawings show:
Fig. 1:
a cross section through a ceiling and / or wall lamp according to an advantageous embodiment of the invention, which shows a seated on a printed circuit board illuminants, the reflector assembly associated therewith and the heat sink surrounding the circuit board and the reflector assembly, and
Fig. 2:
a plan view of the circuit board Fig. 1 showing the arrangement of the bulbs on this printed circuit board.

Die in den Figuren gezeichnete Wand- und/oder Deckenlampe 1 besitzt eine insgesamt längliche - grob gesprochen - barrenförmige Kontur, so dass sie in vorteilhafter Weise in schlitzförmige Ausnehmungen in Decken- und/oder Wandpaneele integriert werden kann, beispielsweise in entsprechende Paneelschlitze versenkt eingebaut werden kann. Auch wenn diese Einbaumöglichkeit aufgrund der geringen Baugröße der Lampe 1 deren Vorteile besonders deutlich zeigt, kann in alternativer Verwendung die Lampe allerdings auch in vorspringender Anordnung, sozusagen auf Putz und/oder freistehend an entsprechenden Befestigungsvorrichtungen und Halterungen befestigt sein.The drawn in the figures wall and / or ceiling lamp 1 has a total elongated - roughly speaking - bar-shaped contour, so that they can be advantageously integrated into slot-shaped recesses in ceiling and / or wall panels, for example, installed countersunk into corresponding panel slots can. Although this installation option shows its advantages particularly clearly due to the small size of the lamp 1, in alternative use, however, the lamp can also be mounted in a projecting arrangement, so to speak on plaster and / or freestanding on corresponding fastening devices and brackets.

In der gezeichneten Ausführung umfasst die Lampe 1 eine Vielzahl von Leuchtmitteln 2 in Form von knopfförmigen LEDs 3, die unmittelbar auf einer Leiterplatine 4 montiert und an Leiter angeschlossen sind, die im Inneren der Leiterplatine 4 integriert sind. Wie Fig. 2 zeigt, können die LEDs 3 dabei vorteilhafterweise voneinander beabstandet nebeneinander aufgereiht sein, wobei für eine Schlitzleuchte die in Fig. 2 gezeigte Aufreihung entlang einer geraden Linie besonders vorteilhaft sein kann. In der gezeichneten Ausführung sind dabei verschiedenfarbige LEDs 3 vorgesehen, deren Licht sich im Zielbereich vorteilhafterweise homogen durchmischen kann, so dass eine einfache Einstellung homogener Lichtfarben gegeben ist, die durch eine gute Farbüberlagerung im Zielbereich erreicht wird.In the illustrated embodiment, the lamp 1 comprises a plurality of light sources 2 in the form of button-shaped LEDs 3, which are mounted directly on a printed circuit board 4 and connected to conductors which are integrated in the interior of the printed circuit board 4. As Fig. 2 shows, the LEDs 3 can advantageously be spaced apart from each other side by side, with a slot lamp in the Fig. 2 shown alignment along a straight line can be particularly advantageous. In the illustrated embodiment, differently colored LEDs 3 are provided, the light of which can advantageously homogeneously mix in the target area, so that a simple adjustment of homogeneous light colors is achieved, which is achieved by a good color overlay in the target area.

Die Leiterplatine 4 besitzt in der gezeichneten Ausführungsform eine lang gestreckte, etwa rechteckförmige Kontur, wobei sie vorteilhafterweise eben ausgebildet ist. Die Leiterplatine 4 kann hierbei als sozusagen endloses Halbzeug gefertigt sein, das dann je nach gewünschter Lampengröße auf die benötigte Länge abgelängt wird. Über die im Korpus der Leiterplatine 4 integrierten und/oder auf der Oberfläche der Leiterplatine 4 aufgebrachten Leiterbahnen, vgl. Fig. 2, werden die auf der Leiterplatine 4 sitzenden LEDs 3 mit elektrischer Energie versorgt und angesteuert. Durch die Anordnung der LEDs 3 unmittelbar auf der Leiterplatine 4 lässt sich eine besonders kompakte Bauweise der Lampe 1 realisieren und eine gute Wärmeableitung bewerkstelligen. Die in den Figuren dargestellte Lampe 1 kann beispielsweise im Querschnitt betrachtet, wie dies Fig. 1 zeigt, Querschnittsmaße von weniger als 100 mm in der Breite und weniger als 50 mm in der Höhe besitzen. Die Länge der Lampe ist dabei vorteilhafterweise nahezu frei wählbar, da die als Endlos-Strangprofile ausgebildeten Bauteile auf die gewünschte Länge ablängbar und entlang der Leiterplatine 4 eine entsprechende beliebige Vielzahl von Leuchtmitteln 2 angeordnet werden kann.The printed circuit board 4 has in the illustrated embodiment an elongated, approximately rectangular contour, wherein it is advantageously formed flat. The printed circuit board 4 can be made as a semi-finished product, so to speak, which is then cut to the required length depending on the desired lamp size. About the integrated in the body of the printed circuit board 4 and / or applied to the surface of the printed circuit board 4 printed conductors, see. Fig. 2 , are seated on the printed circuit board 4 LEDs 3 are supplied with electrical energy and controlled. The arrangement of the LEDs 3 directly on the printed circuit board 4 can be a particularly compact design of the lamp 1 realize and bring about a good heat dissipation. The lamp 1 shown in the figures, for example, viewed in cross section, as this Fig. 1 shows, cross-sectional dimensions of less than 100 mm in width and less than 50 mm in height. The length of the lamp is advantageously almost arbitrary, since the formed as continuous extruded profiles components can be cut to the desired length and along the circuit board 4 a corresponding arbitrary plurality of bulbs 2 can be arranged.

Wie Fig. 1 zeigt, ist der Leiterplatine 4 und den darauf angeordneten LEDs 3 eine Reflektoranordnung 5 zugeordnet, die beidseitig der Leuchtdioden 3 an die Leiterplatine 4 angrenzt und die LEDs 3 zusammen mit der Leiterplatinenvorderseite sozusagen umschließt. Die genannte Reflektoranordnung 5, die unmittelbar an die Leiterplatine 4 angrenzt, definiert dabei mit Reflektorflächenrändern 6 und 7 einen schlitzförmigen Lichtaustrittsquerschnitt 8, der in einer Ebene liegt, welche sich im Wesentlichen - grob gesprochen - senkrecht zur Ebene der Leiterplatine 4 erstreckt, vgl. Fig. 1.As Fig. 1 shows, the printed circuit board 4 and the LEDs 3 disposed thereon is associated with a reflector assembly 5, which is adjacent to both sides of the light emitting diodes 3 to the printed circuit board 4 and the LEDs 3, so to speak encloses together with the printed circuit board front side. Said reflector arrangement 5, which directly adjoins the printed circuit board 4, defines with reflector surface edges 6 and 7 a slot-shaped light exit cross-section 8, which lies in a plane which essentially - roughly speaking - extends perpendicularly to the plane of the printed circuit board 4, cf. Fig. 1 ,

Die Reflektoranordnung 5 umfasst dabei in der gezeichneten Ausführung zwei Reflektoren 9 und 10, wobei ein erster Reflektor 9 vom auszuleuchtenden Raum aus betrachtet hinter den Leuchtdioden 3 angeordnet ist, während der zweite Reflektor 10 aus der genannten Richtung betrachtet vor den Leuchtdioden 3 angeordnet ist und diese sozusagen als Blende abdeckt, so dass von den Leuchtdioden 3 kein direktes Licht in den auszuleuchtenden Raum geworfen werden kann. Die Leuchtdioden 3 sind von der Reflektoranordnung 5 abgeblendet bzw. derart verdeckt, dass sie nicht direkt zu sehen sind.The reflector assembly 5 comprises in the illustrated embodiment, two reflectors 9 and 10, wherein a first reflector 9 is viewed from the illuminated space behind the light emitting diodes 3, while the second reflector 10 is viewed from the direction mentioned in front of the light emitting diodes 3 is arranged and this so to speak covers as a screen, so that no direct light can be thrown from the LEDs 3 in the space to be illuminated. The LEDs 3 are dimmed by the reflector assembly 5 or concealed so that they are not directly visible.

Der genannte zweite Reflektor 10 ist dabei, wie Fig. 1 zeigt, unmittelbar an den Leuchtdioden 3 angeordnet, d.h. der zweite Reflektor 10 sitzt bei der in Fig. 1 gezeichneten Ausrichtung unmittelbar unter den Leuchtdioden 3 an der Leiterplatine 4. Dieser äußerst geringe Abstand bzw. die unmittelbar angrenzenden Anordnung des zweiten Reflektors 10 bewirkt, dass der virtuelle Bildpunkt der Leuchtdioden 3, der von dem zweiten Reflektor 10 auf den ersten Reflektor 9 geworfen wird, dort in unmittelbarer Nähe des direkt von den Leuchtdioden 3 auf den ersten Reflektor 9 geworfenen Bildpunkt liegt, so dass eine zielgerichtete Leuchtdichteverteilung im auszuleuchtenden Zielbereich erreicht wird.The said second reflector 10 is, as Fig. 1 shows, arranged directly on the light-emitting diodes 3, that is, the second reflector 10 is seated in the in Fig. 1 drawn orientation directly below the LEDs 3 on the printed circuit board 4. This extremely small distance or the immediately adjacent arrangement of the second reflector 10 causes the virtual pixel of the LEDs 3, which is thrown from the second reflector 10 to the first reflector 9, there in the immediate vicinity of the directly from the LEDs 3 to the first reflector. 9 Thrown pixel is located so that a targeted luminance distribution is achieved in the target area to be illuminated.

Wie Fig. 1 zeigt, sind die beiden Reflektoren 9 und 10 dabei unterschiedlich ausgebildet. In der gezeichneten Ausführung ist der erste Reflektor 9 rinnenförmig konvex gekrümmt, während der zweite Reflektor 10 im Wesentlichen eben ausgebildet ist. In der gezeichneten Ausführungsform nimmt dabei der Krümmungsradius des ersten Reflektors 9 mit zunehmendem Abstand von der Leiterplatine 4 ab. Flächenmäßig sind die beiden Reflektoren 9 und 10 ebenfalls unterschiedlich ausgebildet. Der erste Reflektor 9 ist wesentlich größer ausgebildet als der zweite Reflektor 10. Letzterer besitzt - grob gesprochen - lediglich etwa ein Viertel bis ein Drittel der Fläche des ersten Reflektors 9, wobei sich dieses Verhältnis je nach Ausbildung der Reflektorgeometrie ggf. auch ändern kann.As Fig. 1 shows, the two reflectors 9 and 10 are formed differently. In the illustrated embodiment, the first reflector 9 is convexly curved in the shape of a channel, while the second reflector 10 is essentially planar. In the illustrated embodiment, the radius of curvature of the first reflector 9 decreases with increasing distance from the printed circuit board 4. Surface area, the two reflectors 9 and 10 are also formed differently. The first reflector 9 is formed substantially larger than the second reflector 10. The latter has - roughly speaking - only about a quarter to a third of the surface of the first reflector 9, wherein this ratio may also change depending on the design of the reflector geometry.

Wie Fig. 1 zeigt, ist der zweite Reflektor 9 zur Leiterplatte 4 und/oder zur Ebene des Lichtaustrittsquerschnitts 8 spitzwinklig geneigt angestellt, insbesondere zu dem ersten Reflektor 9 hin verkippt, wobei er eine gedachte Verbindungslinie zwischen den Leuchtdioden 3 und dem Reflektorflächenrand 6 des ersten Reflektors 9 durchschneidet bzw. überdeckt. Hierdurch wird die direkte Sichtachse auf die LEDs 3 und die damit einhergehende Blendwirkung beseitigt.As Fig. 1 shows, the second reflector 9 to the circuit board 4 and / or the plane of the light exit cross section 8 inclined at an angle, tilted in particular to the first reflector 9, wherein it cuts through an imaginary connecting line between the light emitting diodes 3 and the reflector surface edge 6 of the first reflector 9 or covered. As a result, the direct visual axis is eliminated on the LEDs 3 and the associated glare.

In der gezeichneten Ausführung erstreckt sich der erste Reflektor 9 dabei bogenförmig etwa - grob gesprochen - von dem den Leuchtdioden 3 abgewandten Rand der Leiterplatine 4 bis etwa herunter auf die Höhe der Leuchtdioden 3, vgl. Fig. 1.In the illustrated embodiment, the first reflector 9 extends arcuately about - roughly speaking - from the edge of the printed circuit board 4 facing away from the LEDs 3 to approximately down to the height of the light-emitting diodes 3, cf. Fig. 1 ,

In der gezeichneten Ausführungsform ist die Leiterplatine 4 sowie die darauf angeordneten Leuchtdioden 3 von einer Schutzverglasung 11 abgedeckt, das transparent, vorzugsweise klar ausgebildet ist und beispielsweise aus Acrylglas bestehen kann. Die Schutzverglasung 11 erstreckt sich dabei vorteilhafterweise auch über bzw. vor dem zweiten Reflektor 10, so dass die Schutzverglasung 11 zusammen mit der Leiterplatine 4 und dem zweiten Reflektor 10 einen Hohlraum 12 begrenzt, in dem die Leuchtdioden 3 angeordnet sind. Die Schutzverglasung 11 ist vorteilhafterweise staubdicht an die angrenzenden Bauteilkonturen angeschlossen.In the illustrated embodiment, the printed circuit board 4 and the light-emitting diodes 3 arranged thereon is covered by a protective glazing 11 which is transparent, preferably of a clear design and can be made of acrylic glass, for example. The protective glazing 11 advantageously also extends over or in front of the second reflector 10, so that the protective glazing 11, together with the printed circuit board 4 and the second reflector 10, delimits a cavity 12, in which the LEDs 3 are arranged. The protective glazing 11 is advantageously connected dust-tight to the adjacent component contours.

Um die durch die Leuchtdioden 3 erzeugte Wärme in ausreichendem Maße abzuführen und eine thermische Überlastung zu vermeiden, ist ein Kühlkörper 13 vorgesehen, der die Reflektoren 9 und 10 der Reflektoranordnung 5 sowie die Leiterplatine 4 jeweils rückseitig umgibt. In der gezeichneten Ausführungsform umfasst der Kühlkörper 13 dabei mehrere Kühlkörperteile, die formschlüssig miteinander verbunden werden können und jeweils eine Vielzahl von Kühlrippen 16 aufweisen. In der gezeichneten Ausführung ist dabei ein erster Kühlkörperteil 14 vorgesehen, der im Wesentlichen die Leiterplatine 4 und den zweiten Reflektor 10 kühlt, während ein zweiter Kühlkörperteil 15 den ersten Reflektor 9 kühlt.In order to dissipate the heat generated by the LEDs 3 sufficiently and to avoid thermal overload, a heat sink 13 is provided, which surrounds the reflectors 9 and 10 of the reflector assembly 5 and the printed circuit board 4 each back.

Insbesondere sitzt die genannte Leiterplatine 4 in einer schlitzförmigen Tasche in dem Kühlkörperteil 15, wobei ein gegenüber liegender Randbereich der Leiterplatine 4 von einem Absatz des anderen Kühlkörperteils 14 formschlüssig umgriffen wird, so dass die Leiterplatine 4 vollflächig und satt gegen die Anschlusskontur des zuvor genannten Kühlkörperteils 15 gedrückt werden kann. Die Anschlussflächen des Kühlkörpers 13 an die Leiterplatine 4 sowie an die Reflektoren 9 und 10 sind jeweils formangepasst, wobei vorteilhafterweise vorgesehen sein kann, dass die Reflektoren 9 und 10 unmittelbar in Form einer Auftragsschicht auf die Oberfläche der genannten Kühlkörper aufgebracht sein können. Mit anderen Worten können die Reflektoren 9 und 10 unmittelbar von entsprechenden Oberflächen der Kühlkörper bzw. von darauf aufgebrachten Beschichten gebildet sein.In order to achieve a good heat transfer from the printed circuit board 4 to the heat sink 13, the printed circuit board 4 sits in the illustrated embodiment in a cooling bag 17 which is bounded by the two heat sink parts 14 and 15, said cooling bag 17 to the contour of the printed circuit board 4th is conformed. In particular, the said printed circuit board 4 is seated in a slot-shaped pocket in the cooling body part 15, wherein an opposite edge region of the printed circuit board 4 is positively embraced by a shoulder of the other heat sink part 14, so that the printed circuit board 4 full and full against the connection contour of the aforementioned cooling body part 15th can be pressed. The connecting surfaces of the heat sink 13 to the printed circuit board 4 and to the reflectors 9 and 10 are each conformed to form, it may be advantageously provided that the reflectors 9 and 10 may be applied directly in the form of a coating layer on the surface of said heat sink. In other words, the reflectors 9 and 10 may be formed directly by corresponding surfaces of the heat sinks or of coatings applied thereon.

Wie Fig. 1 zeigt, sitzt auch die Schutzverglasung 11 mit ihren gegenüber liegenden Rändern in entsprechenden Taschen des Kühlkörpers 13, so dass auch die Schutzverglasung 11 Wärme an die entsprechenden Kühlkörperteile abgeben kann.As Fig. 1 also shows the protective glass 11 with its opposite edges in corresponding pockets of the heat sink 13, so that the Protective glazing 11 can deliver heat to the appropriate heat sink parts.

Um von der Schutzverglasung 11 zurückgeworfenes Licht nicht zu verlieren bzw. durch die Schutzverglasung 11 den Wirkungsgrad möglichst wenig zu beeinflussen, ist in vorteilhafter Weise der Erfindung auch die der Schutzverglasung 11 zugewandte Vorderseite der Leiterplatine 4 reflektierend ausgebildet, wobei nach einer vorteilhaften Ausführung der Erfindung die Vorderseite der Leiterplatine 4 weiß beschichtet bzw. lackiert sein kann.In order not to lose light reflected by the protective glazing 11 or to influence the efficiency as little as possible by the protective glazing 11, the protective glass 11 facing front side of the printed circuit board 4 is formed in an advantageous manner of the invention, wherein according to an advantageous embodiment of the invention Front side of the printed circuit board 4 can be white coated or painted.

Wie Fig. 1 zeigt, können vorteilhafterweise nicht nur die Leiterplatine 4, sondern auch die weiteren wesentlichen Baugruppen der Lampe 1 in Form von Endlos-Strangprofilen ausgebildet sein, so insbesondere die Kühlkörperteile 14 und 15, die Reflektoranordnung 5 sowie die Schutzverglasung 11, so dass in einfacher Art und Weise bei geringer Bauteilvielfalt verschiedene Lampengrößen gefertigt werden können. Die entsprechenden Endlos-Strangprofilteile brauchen lediglich auf die gewünschte Länge abgelängt zu werden.As Fig. 1 shows, advantageously, not only the circuit board 4, but also the other essential components of the lamp 1 can be formed in the form of endless extruded profiles, so in particular the heat sink parts 14 and 15, the reflector assembly 5 and the protective glass 11, so that in a simple way and Way with low component diversity different lamp sizes can be made.
