Description
Die vorliegende Erfindung betrifft eine Optikeinheit für eine Leuchte sowie eine Leuchte mit zumindest einer solchen Optikeinheit.The present invention relates to an optical unit for a lamp and a lamp with at least one such optical unit.
Zum Beleuchten von Räumen und Gegenständen kommen gewöhnlich Leuchtmittel zum Einsatz, die im Betrieb Licht erzeugen. Derartige Leuchtmittel können in einer Optikeinheit aufgenommen sein, die ein Gehäuse oder ein Rahmenteil und/oder eine Aufnahme für das Leuchtmittel zur Verfügung stellt. Denkbar ist es auch, eine solche Optikeinheit mit einem Reflektor auszustatten, um das von dem Leuchtmittel erzeugte Licht zu reflektieren. Problematisch bei derartigen Optikeinheiten ist insbesondere eine ungleichmäßige Ausleuchtung einer größeren Fläche bzw. eines größeren Raums und/oder dass die Reflektoren zu einem Blenden von sich in der Umgebung der Optikeinheit befindenden Personen führen können. Leuchten und Optikeinheiten des Stands der Technik sind in
Die vorliegende Erfindung beschäftigt sich daher mit der Aufgabe, für eine Optikeinheit der eingangs genannten Art sowie für eine Leuchte mit zumindest einer solchen Optikeinheit eine verbesserte oder zumindest andere Ausführungsformen anzugeben, die sich insbesondere durch eine großflächige und/oder gleichmäßige und/oder blendfreie Beleuchtung und/oder einfache Herstellung auszeichnen.The present invention is therefore concerned with the task of providing for an optical unit of the type mentioned and for a luminaire with at least one such optical unit an improved or at least other embodiments, in particular by a large and / or uniform and / or glare-free lighting and / or simply manufacture.
Diese Aufgabe wird erfindungsgemäß durch die Gegenstände der unabhängigen Ansprüche gelöst. Vorteilhafte Ausführungsformen sind Gegenstand der abhängigen Ansprüche.This object is achieved by the subjects of the independent claims. Advantageous embodiments are the subject of the dependent claims.
Die vorliegende Erfindung beruht auf dem allgemeinen Gedanken, eine Optikeinheit für eine Leuchte mit zumindest zwei Optikreihen zu versehen, die jeweils benachbarte optische Linsen aufweisen, wobei die Linsen jeweils das von einem zugehörigen Leuchtmittel erzeugte Licht umlenken und/oder brechen, so dass das vom Leuchtmittel erzeugte Licht gezielt aus der Optikeinheit austreten lassen. Somit ist es möglich, mit der Optikeinheit eine größere Fläche bzw. einen größeren Raum gleichmäßig zu beleuchten. Darüber hinaus kann das Beleuchten mittels der Optikeinheit insbesondere blendfrei, das heißt ohne Blenden von sich in der Umgebung befindenden Personen oder zumindest mit einem verringerten Blenden der Personen, erfolgen.The present invention is based on the general idea to provide an optical unit for a luminaire with at least two rows of optics, the each have adjacent optical lenses, wherein the lenses each redirect the light generated by an associated light source and / or break, so that let the light generated by the light bulbs selectively exit from the optical unit. Thus, it is possible to evenly illuminate a larger area or a larger room with the optical unit. In addition, the illumination by means of the optical unit can in particular be glare-free, that is to say without diaphragms of persons located in the surroundings or at least with a reduced aperture of the persons.
Dem Erfindungsgedanken entsprechend weist die Optikeinheit für eine Leuchte mehrere gerade Optikreihen auf, die jeweils mehrere in Längsrichtung der Optikeinheit benachbarte Linsen aufweisen und die in einer Querrichtung der Optikeinheit nebeneinander angeordnet sind. Ferner ist ein Rahmen vorgesehen, der sich von einer Oberseite der Optikeinheit in einer Höhenrichtung der Optikeinheit bis zu einer Unterseite der Optikeinheit erstreckt und der die Linsen der Optikreihen in einer Umlaufrichtung geschlossen einfasst, wobei die Linsen und der Rahmen in einem einstückig hergestellten, rechteckigen, plattenförmigen und transparenten Kunststoffkörper integral ausgeformt sind. Die Höhenrichtung, die Längsrichtung und die Querrichtung verlaufen senkrecht zueinander. Die Umlaufrichtung läuft um die Höhenrichtung um. Der Kunststoffblock ist in einer Ebene, die sich in der Längsrichtung und in der Querrichtung erstreckt, rechteckig. Die Integralbauweise führt zu sehr engen Lagetoleranzen der einzelnen Linsen zueinander, wodurch eine gleichmäßige Lichtabstrahlung realisierbar ist.According to the idea of the invention, the optical unit for a luminaire has a plurality of straight rows of optics each having a plurality of lenses adjacent in the longitudinal direction of the optical unit and arranged side by side in a transverse direction of the optical unit. Furthermore, a frame is provided, which extends from an upper side of the optical unit in a height direction of the optical unit to a lower side of the optical unit and which encloses the lenses of the optical rows closed in a circumferential direction, wherein the lenses and the frame in an integrally manufactured, rectangular, plate-shaped and transparent plastic body are integrally formed. The height direction, the longitudinal direction and the transverse direction are perpendicular to each other. The direction of rotation runs around the height direction. The plastic block is rectangular in a plane extending in the longitudinal direction and in the transverse direction. The integral design leads to very close tolerances of the individual lenses to each other, whereby a uniform light emission can be realized.
Vorzugsweise kann der Rahmen eine in Höhenrichtung verlaufende, äußere Rahmenwand aufweisen, die in der Umlaufrichtung umläuft. Hierdurch ergibt sich ein hochwertig anmutender seitlicher Abschluss für die Optikeinheit.Preferably, the frame may have a heightwise extending outer frame wall which revolves in the direction of rotation. This results in a high-quality lateral conclusion for the optical unit.
Optional kann vorgesehen sein, dass die Linsen von zumindest zwei der Optikreihen in einer quer zur Längsrichtung und quer zur Höhenrichtung verlaufenden Querrichtung miteinander fluchten. Hierdurch ergibt sich ein geometrisch einfacher, symmetrischer Aufbau, der einerseits relativ preiswert herstellbar ist und andererseits die gewünschte homogene Abstrahlungsleistung begünstigt.Optionally, it can be provided that the lenses of at least two of the optical rows are aligned with one another in a transverse direction running transversely to the longitudinal direction and transversely to the vertical direction. This results in a geometrically simple, symmetrical structure, on the one hand relatively inexpensive to produce and on the other hand favors the desired homogeneous radiation performance.
Ferner ist vorgesehen, dass der Kunststoffkörper zumindest eine zwischen zwei solchen Optikreihen angeordnete und in Höhenrichtung in Richtung der Oberseite abstehende Strebe aufweist. Diese Strebe kann zum Befestigen des Kunststoffkörpers und somit der gesamten Optikeinheit an anderen Komponenten genutzt werden.It is further provided that the plastic body has at least one strut arranged between two such rows of optics and projecting in the height direction in the direction of the upper side. This strut can be used to attach the plastic body and thus the entire optical unit to other components.
Eine erfindungsgemäße Leuchte umfasst zumindest eine Optikeinheit der vorstehend beschriebenen Art sowie zumindest einen Tragrahmen, der an der Oberseite der Optikeinheit so in die Optikeinheit eingesetzt ist, dass der Rahmen auch den Tragrahmen in der Umlaufrichtung geschlossen einfasst. Ferner sind LED-Leuchtmittel vorgesehen, die so angeordnet sind, dass jeder Linse genau ein LED-Leuchtmittel zugeordnet ist, wobei der Kunststoffkörper am Tragrahmen befestigt ist. Der Tragrahmen kann bevorzugt ein Metallbauteil sein und z.B. aus einem Leichtmetall bzw. aus einer Leichtmetalllegierung bestehen. Insbesondere kann es sich hierbei um einen Profilkörper handeln. Dieser vorzugsweise metallische Tragrahmen kann zur Aussteifung des Kunststoffkörpers genutzt werden. Außerdem lassen sich weitere Funktionen der Leuchte an diesem Tragrahmen realisieren. Gleichzeitig kann die hochwertige Optik der Optikeinheit erhalten bleiben, da der Tragrahmen in der Optikeinheit versenkt angeordnet ist. Und zwar an deren von Betrachter abgewandten Rückseite, also an deren Oberseite.A lamp according to the invention comprises at least one optical unit of the type described above and at least one support frame, which is inserted into the optical unit on the upper side of the optical unit such that the frame also encloses the support frame closed in the circumferential direction. Further, LED bulbs are provided, which are arranged so that each lens is associated with exactly one LED bulb, wherein the plastic body is attached to the support frame. The support frame may preferably be a metal component and, for example, consist of a light metal or of a light metal alloy. In particular, this may be a profile body. This preferably metallic support frame can be used to stiffen the plastic body. In addition, other functions of the lamp can be realized on this support frame. At the same time, the high-quality optics of the optical unit can be maintained because the support frame is recessed in the optical unit. Namely, at their back facing away from the viewer, so at the top.
Die Erfindung charakterisiert sich dadurch dass der Kunststoffkörper mehrere zwischen zwei solchen Optikreihen angeordnete und in Höhenrichtung in Richtung der Oberseite abstehende Streben aufweist, die in der Längsrichtung voneinander beabstandet sind. Ferner ist vorgesehen, dass der Tragrahmen für jede dieser Streben eine Durchtrittsöffnung aufweist, durch die die jeweilige Strebe in der Höhenrichtung hindurchtritt. Hierdurch kann die jeweilige Strebe zum Befestigen der Optikeinheit am Tragrahmen verwendet werden.The invention is characterized in that the plastic body has a plurality of struts arranged between two such rows of optics and projecting in the height direction in the direction of the upper side, which struts are spaced apart in the longitudinal direction. It is further provided that the support frame for each of these struts has a passage opening through which the respective strut passes in the height direction. As a result, the respective strut for attaching the optical unit can be used on the support frame.
Gemäß der Erfindung ist ferner vorgesehen, dass die jeweilige Strebe an einer von den Linsen abgewandten Seite des Tragrahmens durch plastische Verformung einen gegenüber der übrigen Strebe in der Querrichtung verbreiterten Kopf aufweist, der in der Höhenrichtung nicht mehr durch die Durchtrittsöffnung herausziehbar ist. Hierdurch vereinfacht sich die Herstellung der Leuchte.According to the invention, it is further provided that the respective strut has on a side facing away from the lenses of the support frame by plastic deformation opposite the other strut in the transverse direction widened head, which is no longer in the height direction can be pulled out through the passage opening. This simplifies the manufacture of the lamp.
Zweckmäßig können die LED-Leuchtmittel an wenigstens einer Platine befestigt sein, die innerhalb des Kunststoffkörpers zwischen dem Tragrahmen und den Optikreihen in der Höhenrichtung eingeklemmt ist. Mit anderen Worten, die jeweilige Platine ist durch Klemmung fixiert, was die Montage vereinfacht. Außerdem kann eine Steuerungselektronik vorgesehen sein, die zur elektrischen Steuerung der Leuchtmittel dient und die am Tragrahmen angeordnet ist. Auch dies vereinfacht den Zusammenbau der jeweiligen Leuchte.Suitably, the LED lighting means may be attached to at least one board, which is clamped within the plastic body between the support frame and the optical rows in the height direction. In other words, the respective board is fixed by clamping, which simplifies the assembly. In addition, an electronic control system can be provided which serves for electrical control of the lamps and which is arranged on the support frame. This also simplifies the assembly of the respective lamp.
Gemäß einer Weiterbildung kann die Steuerungselektronik an einer von der jeweiligen Platine abgewandten Seite des Tragrahmens angeordnet sein.According to a development, the control electronics can be arranged on a side facing away from the respective board side of the support frame.
Dadurch kann die Elektronik unabhängig von der jeweiligen Platine montiert werden.This allows the electronics to be mounted independently of the respective board.
Vorteilhaft kann die Leuchte zumindest zwei solche Optikeinheiten aufweisen, die im einfachsten Fall unmittelbar aneinander stoßen. Bei einer anderen Bauform kann zusätzlich ein Zwischenstück vorgesehen sein, das zwischen den Optikeinheiten angeordnet ist und diese miteinander verbindet. Die beiden Optikeinheiten können in der Längsrichtung oder in der Querrichtung benachbart sein. Dementsprechend kann das gegebenenfalls vorhandene Zwischenstück in der Längsrichtung oder in der Querrichtung zwischen den beiden Optikeinheiten angeordnet sein.Advantageously, the luminaire can have at least two such optical units which in the simplest case abut one another directly. In another design, an intermediate piece may additionally be provided, which is arranged between the optical units and connects them together. The two optical units may be adjacent in the longitudinal direction or in the transverse direction. Accordingly, the optional intermediate piece can be arranged in the longitudinal direction or in the transverse direction between the two optical units.
Eine vorteilhafte Ausführungsform sieht daher vor, dass das Zwischenstück in der Längsrichtung zwischen den beiden Optikeinheiten angeordnet ist und in der Querrichtung bündig mit den Rahmen der beiden Optikeinheiten abschließt. Alternativ kann vorgesehen sein, dass das Zwischenstück in der Querrichtung zwischen den beiden Optikeinheiten angeordnet ist und in der Längsrichtung bündig mit den Rahmen der beiden Optikeinheiten abschließt. In der Folge geht das Zwischenstück stufenlos in die beiden benachbarten Optikeinheiten über.An advantageous embodiment therefore provides that the intermediate piece is arranged in the longitudinal direction between the two optical units and terminates flush in the transverse direction with the frame of the two optical units. Alternatively it can be provided that the intermediate piece is arranged in the transverse direction between the two optical units and terminates flush in the longitudinal direction with the frame of the two optical units. As a result, the intermediate piece passes continuously into the two adjacent optical units.
Vorteilhaft kann die Leuchte einen Sensor aufweisen, der am Zwischenstück angeordnet ist. Ein derartiger Sensor kann beispielsweise ein Bewegungsmelder sein oder die Helligkeit der Umgebung ermitteln, so dass die Steuerung gegebenenfalls die Leuchtstärke der Leuchte abhängig von der Helligkeit der Umgebung nachregeln kann. Auch kann ein solcher Sensor eine Kamera, ein Aktor, ein elektrisches Erfassungssystem oder ähnliches sein.Advantageously, the lamp may have a sensor which is arranged on the intermediate piece. Such a sensor can be, for example, a motion detector or determine the brightness of the environment, so that the controller can optionally adjust the luminous intensity of the luminaire depending on the brightness of the environment. Also, such a sensor may be a camera, an actuator, an electrical detection system or the like.
Eine weitere Ausführungsform sieht vor, dass die Leuchte als eine Pendelleuchte mit einem auf einer Oberseite der Leuchte angeordneten Befestigungselement zum Befestigen der Pendelleuchte an einer an einer Decke befestigbaren Abhängung, z.B. in Form eines Seils oder einer Kette oder dergleichen, ausgebildet ist.A further embodiment provides that the lamp as a pendant lamp with a arranged on an upper side of the lamp fastener for attaching the pendant lamp to a suspension attachable to a ceiling, for example in the form of a rope or a chain or the like, is formed.
Alternativ kann die Leuchte als eine Deckenleuchte mit einem auf einer Oberseite der Leuchte angeordneten und an einer Decke befestigbaren Befestigungselement ausgebildet ist. Alternativ kann die Leuchte als eine Standleuchte mit einem Standfuß zum Abstellen der Leuchte, einer vom Standfuß abstehenden Halterung und einem von der Halterung gehaltenen Leuchtschirm ausgebildet ist, wobei zumindest eine solche Optikeinheit im Leuchtschirm angeordnet ist.Alternatively, the lamp can be configured as a ceiling light with a fastening element arranged on an upper side of the luminaire and attachable to a ceiling. Alternatively, the luminaire can be configured as a floor lamp with a base for shutting off the luminaire, a holder projecting from the base and a luminescent screen held by the holder, at least one such optical unit being arranged in the luminescent screen.
Die jeweilige Linse kann prinzipiell beliebig ausgestaltet sein. Insbesondere kann die jeweilige Linse eine beliebige Form aufweisen. Bevorzugt weist die jeweilige Linse eine halbsphärische Form auf. Besonders bevorzugt ist die jeweilige Linse hin zur Unterseite konkav ausgebildet.The respective lens can in principle be configured as desired. In particular, the respective lens may have any shape. Preferably, the respective lens has a hemispherical shape. Particularly preferably, the respective lens is concave toward the bottom.
Ein Lichtaustrittsabschnitt der Optikeinheit kann derart ausgestaltet sein, dass sämtlichen Linsen bzw. den zugehörigen Leuchtmitteln ein gemeinsamer Lichtaustrittsabschnitt zugeordnet ist. Vorstellbar ist es auch, dass der jeweiligen Optikreihe ein solcher Lichtaustrittsabschnitt zugeordnet ist, so dass die Optikeinheit zumindest zwei solche Lichtaustrittsabschnitte aufweist. Denkbar sind auch Ausführungsformen, bei denen der jeweiligen Linse ein solcher Lichtaustrittsabschnitt zugeordnet ist.A light exit section of the optical unit can be designed in such a way that a common light exit section is assigned to all the lenses or the associated light sources. It is also conceivable that the respective optical line is associated with such a light exit section, so that the optical unit has at least two such light exit sections. Also conceivable are embodiments in which the respective lens is assigned such a light exit section.
Als vorteilhaft erweisen sich Varianten, bei denen die Leuchte ein Linearmodul zum Linearisieren von Licht auf der von der Unterseite abgewandten Seite zumindest einer solchen Linse einer solchen Optikreihe angeordnet ist. Mit dem Linearmodul wird also das über den Lichtaustritt der Linse austretende Licht linearisiert und kann somit homogener bzw. gleichmäßiger abgestrahlt werden. Bevorzugt sind Ausführungsformen, bei denen die Optikeinheit derart ausgestaltet ist, dass das von den Leuchtmitteln erzeugte Licht zu 70 % über die Unterseite und zu 30 % über die Oberseite austritt. Somit wird ein besonders homogenes, gleichmäßiges Beleuchten erreicht. Das nach unten abgestrahlte Licht erzeugt eine direkte Beleuchtung. Das nach oben abgestrahlte Licht sorgt für eine indirekte Beleuchtung. Zweckmäßig sind zum Erzeugen der direkten und der indirekten Beleuchtung separate Leuchtmittel vorgesehen, die separate angesteuert werden können.Variants in which the luminaire is arranged as a linear module for linearizing light on the side of at least one such lens of such a series of optics facing away from the underside are advantageous. With the Linear module is therefore linearized over the light exit of the lens emerging light and thus can be emitted more uniformly or evenly. Preferred are embodiments in which the optical unit is designed such that the light generated by the bulbs emerges 70% over the bottom and 30% over the top. Thus, a particularly homogeneous, uniform illumination is achieved. The light emitted downwards creates a direct illumination. The light emitted upwards ensures indirect lighting. Appropriately, separate light sources are provided for generating the direct and indirect lighting, which can be controlled separately.
Eine zumindest ein solches Leuchtmittel steuernde Steuerungselektronik einer zugehörigen Leuchte ist bevorzugt innerhalb des Rahmens angeordnet. Somit kann die Leuchte insbesondere kompakt ausfallen und/oder benötigt keine äußere elektrische Steuerung, sondern lediglich eine elektrische Versorgung, um betrieben zu werden. Dies vereinfacht den Einsatz der Optikeinheit, insbesondere in der zugehörigen Leuchte, erheblich.A control electronics of an associated luminaire controlling at least one such luminous means is preferably arranged within the frame. Thus, the lamp can be particularly compact and / or requires no external electrical control, but only an electrical supply to be operated. This considerably simplifies the use of the optical unit, in particular in the associated lamp.
Die Linsen der jeweiligen Optikreihe können relativ zueinander beliebig angeordnet sein. Vorstellbar ist es, die Linsen von zwei der Optikreihen relativ zueinander versetzt anzuordnen. Denkbar sind auch Ausführungsformen, bei denen die Linsen von zumindest zwei der Optikreihen in einer quer zur Längsrichtung und quer zur Höhenrichtung verlaufenden Querrichtung miteinander fluchten.The lenses of the respective optical series can be arranged arbitrarily relative to one another. It is conceivable to arrange the lenses of two of the optical rows offset relative to each other. Also conceivable are embodiments in which the lenses of at least two of the optical rows are aligned with one another in a transverse direction running transversely to the longitudinal direction and transversely to the vertical direction.
Die Optikeinheit weist, wie vorstehend erläutert, zumindest zwei solche Optikreihen auf. Bevorzugt sind Ausführungsformen, bei denen die Optikeinheit zumindest drei, insbesondere vier, Optikreihen aufweist. Dies erlaubt insbesondere eine gleichmäßigere Beleuchtung und/oder eine ausreichende Beleuchtung einer zu beleuchtenden Fläche bzw. eines zu beleuchtenden Raums.As explained above, the optical unit has at least two such rows of optics. Embodiments in which the optical unit has at least three, in particular four, rows of optics are preferred. This allows in particular a more uniform illumination and / or sufficient Illumination of a surface to be illuminated or of a room to be illuminated.
Der Kunststoffkörper kann prinzipiell aus einem beliebigen transparenten Kunststoff hergestellt sein. Bevorzugt sind Varianten, bei denen das Rahmenteil aus einem Hartkunststoff hergestellt ist. Dies führt insbesondere zu einer Stabilisierung der Optikeinheit. Der Kunststoffkörper kann dabei aus Polymethylmethacrylat (PMMA), insbesondere aus Acrylglas, hergestellt sein.The plastic body can in principle be made of any transparent plastic. Preferred are variants in which the frame part is made of a hard plastic. This leads in particular to a stabilization of the optical unit. The plastic body can be made of polymethylmethacrylate (PMMA), in particular of acrylic glass.
Der Rahmen kann zumindest eine in Höhenrichtung verlaufende, äußere Rahmenwand aufweisen, welche die Linsen seitlich einfasst und so einen seitlichen Abschluss der Optikeinheit bildet. Bevorzugt ist es dabei, wenn die zumindest eine Rahmenwand umlaufend, insbesondere geschlossen umlaufend verläuft und somit das Innere des Kunststoffkörpers umlaufend, insbesondere geschlossen umlaufend umgibt.The frame may have at least one extending in the vertical direction, outer frame wall which laterally surrounds the lenses and so forms a lateral termination of the optical unit. In this case, it is preferable for the at least one frame wall to run circumferentially, in particular closed circumferentially, and thus surround the interior of the plastic body circumferentially, in particular closed circumferentially.
Bei bevorzugten Ausführungsformen sind der Rahmen und die Linsen der Optikeinheit einstückig, insbesondere materialeinheitlich, ausgebildet. Das heißt, dass der Rahmen und die Linsen sind aus Kunststoff, insbesondere aus PMMA, hergestellt. Insbesondere ist es vorstellbar, den Rahmen und die Linsen durch ein Gussverfahren gemeinsam herzustellen.In preferred embodiments, the frame and the lenses of the optical unit are integrally formed, in particular of the same material. That is, the frame and lenses are made of plastic, especially PMMA. In particular, it is conceivable to manufacture the frame and the lenses together by a casting process.
Die Optikeinheit kommt, wie vorstehend erwähnt, in einer Leuchte zum Einsatz. Dementsprechend gehört eine Leuchte mit einer solchen Optikeinheit ebenfalls zum Umfang dieser Erfindung. Die Leuchte kann dabei insbesondere zwei solche Optikeinheiten aufweisen. Dabei weist die Leuchte neben der Leuchteinheit auch zumindest ein Leuchtmittel auf, vorzugsweise ein LED-Leuchtmittel. Ein LED-Leuchtmittel zeichnet sich durch eine Vielzahl parallel ansteuerbarer LEDs aus. Das jeweilige Leuchtmittel kann jedoch prinzipiell beliebig ausgebildet sein.The optical unit is, as mentioned above, used in a lamp. Accordingly, a luminaire incorporating such an optical unit is also within the scope of this invention. The luminaire may in particular have two such optical units. In this case, the lamp next to the light unit and at least one light source, preferably an LED bulb. An LED illuminant is characterized by a large number of parallel controllable LEDs. However, the respective lighting means can in principle be designed as desired.
Vorstellbar ist es, dass zumindest zwei unterschiedliche Leuchtmittel zum Einsatz kommen. Das jeweilige Leuchtmittel kann hierbei insbesondere eine lichtemittierende Diode (LED), eine Glühbirne und dergleichen sein.It is conceivable that at least two different lamps are used. In this case, the respective lighting means may in particular be a light-emitting diode (LED), a light bulb and the like.
Als vorteilhaft erweisen sich Varianten, bei denen die Leuchte einen, insbesondere als Metallprofil ausgestalteten, Tragrahmen aufweist, der im Rahmen der Optikeinheit angeordnet ist. Bevorzugt liegt der Tragrahmen an zumindest einer solchen Rahmenwand des Rahmens an. Der Tragrahmen aus Metall stabilisiert die Optikeinheit. Zudem kann über den metallischen Tragrahmen Wärme abgeführt werden.Variants in which the luminaire has a supporting frame, in particular a metal profile, which is arranged in the frame of the optical unit prove to be advantageous. Preferably, the support frame bears against at least one such frame wall of the frame. The metal support frame stabilizes the optical unit. In addition, heat can be dissipated via the metallic support frame.
Bevorzugt ist es, wenn zumindest eine Strebe des Kunststoffkörpers durch das den Tragrahmen geführt und am Tragrahmen befestigt ist. Hierzu kann der Tragrahmen Öffnungen, insbesondere Langlöcher aufweisen, durch welche die Streben geführt sind. Bevorzugt sind die Streben nur im Bereich von Vorsprüngen durch die jeweilige Öffnung des Tragrahmens hindurchgeführt, die von der übrigen Strebe in der Höhenrichtung abstehen. Sofern zwei oder mehr Optikeinheiten vorgesehen sind, kann ein gemeinsamer Tragrahmen vorgesehen sein, an dem beide Optikeinheiten befestigt sind.It is preferred if at least one strut of the plastic body is guided through the support frame and secured to the support frame. For this purpose, the support frame openings, in particular slots have, through which the struts are guided. Preferably, the struts are guided only in the region of projections through the respective opening of the support frame, which protrude from the rest of the strut in the height direction. If two or more optical units are provided, a common support frame may be provided to which both optical units are attached.
Vorstellbar ist es, die Leuchte mit zumindest zwei solchen Optikeinheiten zu versehen und wenigstens zwei der Optikeinheiten alternativ oder zusätzlich zum Metallprofil über ein Zwischenstück miteinander zu verbinden. Das Vorsehen des Zwischenstücks ermöglicht es, die Optikeinheiten auf einfache Weise miteinander elektrisch und/oder mechanisch zu verbinden. Insbesondere müssen die Optikeinheiten hierdurch keine Bestandteile und/oder Strukturen aufweisen, um sie unmittelbar mit einer anderen Optikeinheit zu verbinden. Ein solches Zwischenstück ermöglicht es zudem, die Optikeinheiten in einer prinzipiell beliebigen Anordnung relativ zueinander miteinander zu verbinden. Zweckmäßig kann auch das jeweilige Zwischenstück am gemeinsamen Tragrahmen befestigt sein.It is conceivable to provide the lamp with at least two such optical units and to connect at least two of the optical units alternatively or in addition to the metal profile via an intermediate piece with each other. The provision of the intermediate piece makes it possible to easily connect the optical units with each other electrically and / or mechanically. In particular, the optical units thereby have no components and / or structures in order to connect them directly to another optical unit. Such an intermediate piece also makes it possible to connect the optical units in a basically arbitrary arrangement relative to each other. expedient can also be the respective spacer attached to the common support frame.
In der Leuchte können zumindest zwei Optikeinheiten in der Längsrichtung benachbart angeordnet sein. Somit ist es möglich, die Optikreihen der jeweiligen Optikeinheit entlang der Längsrichtung fluchtend, insbesondere durch das Zwischenstück unterbrochen, anzuordnen.In the luminaire, at least two optical units may be arranged adjacent in the longitudinal direction. Thus, it is possible, the optical lines of the respective optical unit along the longitudinal direction aligned, in particular interrupted by the intermediate piece to arrange.
Denkbar sind auch Ausführungsformen, bei denen zumindest zwei der Optikeinheiten in der Querrichtung benachbart angeordnet sind. Hierdurch ist eine breitere Ausbildung der Leuchte möglich.Also conceivable are embodiments in which at least two of the optical units are arranged adjacent in the transverse direction. As a result, a broader design of the lamp is possible.
Die Leuchte kann außer den Optikeinheiten beliebige andere Bestandteile aufweisen, die insbesondere der Halterung, dem Steuern, der elektrischen Versorgung und dergleichen dienen.The lamp may have any other components besides the optical units, which serve in particular the holder, the control, the electrical supply and the like.
Denkbar sind Ausführungsformen, bei denen die Leuchte einen Sensor aufweist, der dem Steuern und/oder dem Betreiben der Leuchte dient. Ein derartiger Sensor kann beispielsweise ein Bewegungsmelder sein oder die Helligkeit der Umgebung ermitteln. Auch kann ein solcher Sensor eine Kamera, ein Aktor, ein elektrisches Erfassungssystem oder ähnliches sein. Mit Hilfe des Sensors ist es beispielsweise möglich, die Leuchtmittel der Leuchte zumindest teilweise zu aktivieren, wenn äußere Umstände eintreten, beispielsweise wenn sich eine Person in der Umgebung der Leuchte befindet. Bevorzugt ist es dabei, wenn ein solcher Sensor im Zwischenstück der Leuchte vorgesehen, insbesondere integriert ist. Somit wird der Aufbau der Leuchte vereinfacht.Conceivable are embodiments in which the luminaire has a sensor which serves to control and / or operate the luminaire. Such a sensor may for example be a motion detector or determine the brightness of the environment. Also, such a sensor may be a camera, an actuator, an electrical detection system or the like. With the aid of the sensor, it is possible, for example, to at least partially activate the luminous means of the luminaire when external circumstances occur, for example when a person is in the vicinity of the luminaire. It is preferred if such a sensor is provided in the intermediate piece of the luminaire, in particular integrated. Thus, the structure of the lamp is simplified.
Die erfindungsgemäße Leuchte sowie die erfindungsgemäße Optikeinheit erlauben eine einfache Ausbildung der Leuchte z.B. durch ein modulares Baukastensystem. Dieses modulare Baukastensystem stellt solche Optikeinheiten zur Verfügung, die zum Ausbilden der Leuchte miteinander verbunden werden können. Die jeweilige Optikeinheit ist also ein Optikmodul, das mit anderen Optikeinheiten, also Optikmodulen, verbunden wird, um die Leuchte herzustellen bzw. auszubilden.The lamp according to the invention and the optical unit according to the invention allow a simple design of the lamp, for example by a modular Modular system. This modular modular system provides such optical units that can be interconnected to form the luminaire. The respective optical unit is thus an optical module, which is connected to other optical units, so optical modules, to produce or form the lamp.
Das Baukastensystem kann dabei neben den Optikeinheiten bzw. Optikmodulen auch solche Zwischenstücke und/oder Metallprofile aufweisen, um die Optikeinheiten auf einfache Weise miteinander zu verbinden. Die Zwischenstücke und/oder die Metallprofile können also als Verbindungsmodule bezeichnet werden, die zum Verbinden der Optikeinheiten bzw. Optikmodule zum Einsatz kommen.The modular system can in addition to the optical units or optical modules and such intermediate pieces and / or metal profiles have to connect the optical units in a simple manner with each other. The intermediate pieces and / or the metal profiles can therefore be referred to as connection modules, which are used for connecting the optical units or optical modules.
Vorstellbar ist es dabei, dass zumindest zwei der Optikeinheiten, insbesondere zwei der Optikmodule, unterschiedlich ausgebildet sind, insbesondere unterschiedliche Dimensionierungen aufweisen. Vorstellbar ist es, dass zumindest zwei der Optikeinheiten bzw. Optikmodule unterschiedliche, in Längsrichtung verlaufende Längen aufweisen. Somit kann insbesondere eine größere Variabilität der mittels der Optikeinheiten, insbesondere der Optikmodule des modularen Baukastensystems, hergestellten Leuchten erreicht werden.It is conceivable that at least two of the optical units, in particular two of the optical modules, are designed differently, in particular have different dimensions. It is conceivable that at least two of the optical units or optical modules have different longitudinally extending lengths. Thus, in particular, a greater variability of the luminaires produced by means of the optical units, in particular the optical modules of the modular modular system, can be achieved.
Prinzipiell können mit den Optikeinheiten bzw. den Optikmodulen beliebige Arten von Leuchten hergestellt werden.In principle, any type of luminaire can be produced with the optical units or the optical modules.
Vorstellbar ist es, eine solche Leuchte als eine Pendelleuchte auszubilden, wobei die Pendelleuchte auf der Oberseite mit einem Befestigungselement versehen ist, das dem Befestigen der Pendelleuchte an einer Abhängung, wie z.B. einem Seil, einer Kette oder dergleichen, die an einer Decke befestigt oder befestigbar ist, dient. Auch ist es vorstellbar, dass die Pendelleuchte auf der Oberseite zumindest zwei solcher Befestigungselemente aufweist.It is conceivable to form such a lamp as a pendant lamp, wherein the pendant lamp is provided on the upper side with a fastening element, which attaches the pendant lamp to a suspension, such as a rope, a chain or the like, which is attached to a ceiling or fastened is serves. It is also conceivable that the pendant lamp has at least two such fastening elements on the upper side.
Denkbar ist es, die Leuchte als eine Deckenleuchte auszubilden, die an einer Decke befestigt ist, wobei die Deckenleuchte auf der Oberseite zumindest ein Befestigungsmittel aufweist, mit dem sie an einer Decke befestigbar ist. Die Deckenleuchte kann dabei als eine Einbauleuchte oder als eine Anbauleuchte ausgebildet sein.It is conceivable to design the lamp as a ceiling lamp, which is fastened to a ceiling, wherein the ceiling lamp has on the upper side at least one fastening means with which it can be fastened to a ceiling. The ceiling light can be designed as a recessed luminaire or as a surface-mounted luminaire.
Zu denken ist auch an Ausführungsformen, bei denen die Leuchte als eine Standleuchte ausgebildet ist, die einen Standfuß zum Abstellen der Standleuchte und einen Leuchtschirm aufweist, wobei zumindest eine solche Optikeinheit im Leuchtschirm angeordnet ist. Der Leuchtschirm ist von einer Halterung der Standleuchte gehalten, der vom Standfuß absteht.It is also to be considered in embodiments in which the lamp is designed as a floor lamp, which has a base for parking the floor lamp and a fluorescent screen, wherein at least one such optical unit is arranged in the phosphor screen. The screen is held by a holder of the floor lamp, which protrudes from the stand.
Dementsprechend kann das modulare Baukastensystem mit solchen Befestigungselementen und/oder mit solchen Standfüßen, Halterungen und Leuchtschirmen versehen sein, um das modulare Herstellen der jeweiligen Leuchte zu ermöglichen.Accordingly, the modular modular system can be provided with such fasteners and / or with such feet, brackets and luminescent screens to allow the modular manufacture of the respective lamp.
Es versteht sich, dass neben einer solchen Optikeinheit und einer solchen Leuchte auch ein modulares Baukastensystem der beschriebenen Art zum Herstellen einer solchen Leuchte zum Umfang dieser Erfindung gehört.It is understood that, in addition to such an optical unit and such a luminaire, a modular system of the type described for producing such a luminaire belongs to the scope of this invention.
Das modulare Baukastensystem umfasst hierbei zumindest zwei solche Optikmodule, die zum Herstellen der Leuchte dem Baukastensystem entnommen und miteinander verbunden werden. Dabei kann das Baukastensystem zumindest zwei unterschiedliche Arten von Optikmodulen aufweisen, wobei das Baukastensystem von der jeweiligen Art mehrere Optikmodule umfassen kann.The modular system here comprises at least two such optical modules, which are taken from the modular system and connected to each other for the manufacture of the lamp. In this case, the modular system may have at least two different types of optical modules, wherein the modular system of the respective type may comprise a plurality of optical modules.
