Description
<Desc/Clms Page number 1>
Die vorliegende Erfindung betrifft ein Leuchtenfeld zur Beleuchtung von Räumen mit einer Vielzahl von LEDs, wobei mehrere, insbesondere glaskörperfreie, LEDs auf mindestens einer gemeinsamen Trägerplatine angeordnet sind und mindestens ein Reflektorkörper vor mindestens einer gemeinsamen Trägerplatine angeordnet ist.
Gattungsgemässe Leuchtenfelder sind z. B. aus der EP 0762515 A2 bekannt. Nachteil beim Stand der Technik ist hierbei, dass der Reflektorkörper aus Einzelreflektoren aufgebaut ist, welche in aufwendiger Arbeit an einem gemeinsamen Träger angeordnet, z. B. aufgeklebt werden müssen.
Aufgabe der Erfindung ist es somit, ein Leuchtenfeld zu schaffen, bei dem die oben angeführten Nachteile des Standes der Technik beseitigt sind Dies wird erfindungsgemäss dadurch erreicht, dass der Reflektorkörper als mindestens ein, vorzugsweise einstückiges, Spritzgussteil ausgebildet ist.
Diese Art der Herstellung der Reflektorkörper ist besonders bei grossen Stückzahlen ganz besonders einfach und günstig durchführbar. Gleichzeitig ist eine erhebliche Gestaitungsfreiheit für verschiedene erfindungsgemässe Refiektorkörper beim heutigen Stand der Spritzgusstechnik gegeben.
Besonders günstig ist es, dass der Reflektorkörper für jede LED einen vorzugsweise paraboloidförmigen Einzelreflektor aufweist. Darüber hinaus ist es in einer weiteren Ausführungsform vorgesehen, dass der Reflektorkörper für jede LED mindestens einen asymmetrischen Einzelreflektor aufweist. Eine weitere Ausbildungsform sieht vor, dass der Reflektorkörper mindestens zwei verschieden ausgebildete Einzelreflektoren aufweist. Durch diese verschiedenen günstigen Ausführungsformen kann eine Vielzahl von Lichteffekten durch die entsprechende Formgebung der jeweiligen Einzelreflektoren herbeigeführt werden.
Diese Lichteffekte können z. B. zur gezielten Ausleuchtung von speziellen Raumbereichen, aber auch zur gezielten Ausbildung von optischen Beleuchtungseffekten genutzt werden.
Eine besonders günstige Ausführungsform sieht darüber hinaus vor, dass verschiedene LEDs auf mindestens einer gemeinsamen Trägerplatine verschieden farbiges Licht abstrahlen.
Neben der reinen Beeinflussung der Abstrahlrichtung kann die Lichtwirkung des Leuchtenfeldes somit auch durch die Beeinflussung und Mischung des Farbinhalts des abgestrahlten Lichts beeinflusst werden.
<Desc/Clms Page number 2>
Günstige Ausführungsformen sehen hierbei vor, dass mindestens eine gemeinsame Trägerplatine und/oder mindestens zwei Einzelreflektoren bereichsweise verschiedenfarbig ausgebildet ist (sind) und/oder verschiedene Trägerplatinen und/oder LED's verschiedene Farben aufweisen.
Neben dieser zunächst zeitlich konstanten Mischung von verschiedenfarbigem Licht zur Erzielung gewünschter Beleuchtungseffekte sieht eine besonders günstige Ausführungsform darüber hinaus vor, dass verschiedene LEDs und/oder LED-Gruppen - vorzugsweise zur Mischung verschiedener Farbtemperaturen von weissem Licht und/oder zur Mischung von verschiedenfarbigem Licht - einzeln dimmbar ausgebildet sind. Durch diese Ausbildungsform ist auch eine zeitliche Variation sowohl der Licht- und Farbeffekte als auch der Stärke des abgestrahlten Lichts für einzelne Raumbereiche möglich. Es können dadurch sowohl bestimmte Raumbereiche stärker oder schwächer beleuchtet werden, als auch verschiedene Farbtemperaturen des abgestrahlten Lichts selektiv oder im ganzen Raum erzeugt und zeitlich variiert werden.
Es entsteht somit eine grosse gestalterische Freiheit bei der Beleuchtung von Räumen durch die verschiedenen Ausbildungsformen des erfindungsgemässen Leuchtenfeldes.
Ein besonders günstiger Vorteil derartiger Leuchtenfelder ist, dass sie bei Bedarf mit einer sehr geringen Bauhöhe gefertigt werden können, wobei die Bauhöhe die Gesamtdicke des Leuchtenfeldes normal zu seiner Trägerplatine bezeichnet. So sehen günstige Varianten vor, dass das Leuchtenfeld eine Bauhöhe kleiner 3 bis 4 cm, vorzugsweise kleiner 2 bis 3 cm, aufweist.
Weitere Merkmale und Einzelheiten der vorliegenden Erfindung ergeben sich aus der nachfolgenden Figurenbeschreibung. Dabei zeigt: Fig. 1 ein Leuchtenfeld mit einem erfindungsgemässen Reflektorkörper, Fig. 2 einen Reflektorkörper mit asymmetrischen Einzelreflektoren und Fig. 3 einen Reflektorkörper mit asymmetrischen Einzelreflektoren sowie verschiedenartigen Einzelreflektoren Fig. 1 zeigt einen Ausschnitt eines erfindungsgemässen Leuchtenfeldes. Hier sind auf einer Trägerplatine 3 verschiedene LEDs 4 aufgebracht und in der Trägerplatine entsprechend gemäss dem Stand der Technik verdrahtet. Die Verteilung der LEDs 4 auf der Trägerplatine 3
<Desc/Clms Page number 3>
kann hierbei wie dargestellt gleichmässig aber auch beliebig ungleichmässig vorgenommen sein. Die Ansteuerung und Dimmung der einzelnen LEDs wird durch eine geeignete Steuereinrichtung 5 vorgenommen.
Erfindungsgemäss ist vor der Trägerplatine 3 ein Reflektorkörper 1 angeordnet. Der Reflektorkörper 1 ist hierbei erfindungsgemäss vorzugsweise einstückig als Spritzgussteil ausgeführt. Der Reflektorkörper 1 weist vorzugsweise für jede einzelne LED einen entsprechenden für paraboloidförmigen Einzelreflektor 2 auf. In Fig. 1 sind der Übersichtlichkeit halber die Trägerplatine 3 und der Reflektorkörper 1 getrennt dargestellt. Bei dem erfindungsgemässen Leuchtenfeld ist der Reflektorkörper 1 jedoch vorzugsweise direkt auf der Trägerplatine 3 befestigt, sodass die LEDs 4 in die ihnen zugeordneten Ausnehmungen 6 der Einzelreflektoren hineinreichen.
Dabei ist es besonders günstig, wenn die LEDs 4 glaskörperfrei ausgebildet sind, es können jedoch auch LEDs mit Glaskörpern z. B. zur Erzeugung von Farbeffekten verwendet werden In einer günstigen Ausbildungsform ist vorgesehen, dass die LEDs 4 und/oder die Trägerplatine 3 und/oder die Einzelreflektoren 2 verschiedenfarbig und/oder bereichsweise verschiedenfarbig ausgebildet sind. Dies ermöglicht eine Ausbildung von verschiedenen Farbtemperaturen in verschiedenen Bereichen des durch das Leuchtenfeld ausgeleuchteten Raumes. Durch die Dimmeinrichtung 5 ist hierbei auch eine zeitliche Veränderung der verschiedenen Beleuchtungsstärken bzw. Farbtemperaturen oder Farbmischungen neben der Generierung von weissem Licht möglich. Das Leuchtenfeld kann darüber hinaus sowohl an Deckenund Wändenals auch z.B. unter Glas in Fussbödenangebracht sein.
Fig. 2 zeigt eine von vielen möglichen Ausbildungsformen des erfindungsgemässen Leuchtenfeldes mit asymmetrischen und verschieden ausgebildeten Einzelreflektoren 2.
Fig. 3 zeigt eine Ausführungsvariante mit asymmetrischen, symmetrischen und verschiedene Formen aufweisenden Einzelreflektoren 2 Darüber hinaus ist auch die Variation anderer geometrischer Abmessungen des Reflektorkörpers 1, wie zum Beispiel die Variation seiner Dicke bzw. die Ausbildung einer Krümmung seiner Oberflächen möglich (hier nicht dargestellt).

The present invention relates to a luminaire field for illuminating rooms with a large number of LEDs, several, in particular vitreous-free, LEDs being arranged on at least one common carrier board and at least one reflector body being arranged in front of at least one common carrier board.
Generic lighting fields are e.g. B. known from EP 0762515 A2. A disadvantage of the prior art is that the reflector body is made up of individual reflectors, which are arranged on a common support in a laborious process, e.g. B. must be glued on.
The object of the invention is therefore to create a luminaire field in which the above-mentioned disadvantages of the prior art are eliminated. This is achieved according to the invention in that the reflector body is designed as at least one, preferably one-piece, injection-molded part.
This type of manufacture of the reflector bodies is particularly easy and inexpensive to carry out, particularly in the case of large quantities. At the same time, there is considerable freedom of movement for various reflector bodies according to the invention in the current state of injection molding technology.
It is particularly favorable that the reflector body has a preferably paraboloidal individual reflector for each LED. In addition, it is provided in a further embodiment that the reflector body has at least one asymmetrical individual reflector for each LED. Another embodiment provides that the reflector body has at least two differently designed individual reflectors. Through these various favorable embodiments, a large number of light effects can be brought about by the corresponding shaping of the respective individual reflectors.
These lighting effects can e.g. B. for the targeted illumination of special room areas, but also for the targeted training of optical lighting effects.
A particularly favorable embodiment also provides that different LEDs emit differently colored light on at least one common carrier board.
In addition to simply influencing the direction of radiation, the lighting effect of the luminaire field can also be influenced by influencing and mixing the color content of the emitted light.
<Desc / Clms Page number 2>
Favorable embodiments provide that at least one common carrier board and / or at least two individual reflectors is (are) of different colors in some areas and / or different carrier boards and / or LEDs have different colors.
In addition to this mixture of differently colored light, which is initially constant over time, in order to achieve desired lighting effects, a particularly favorable embodiment also provides that different LEDs and / or LED groups - preferably for mixing different color temperatures of white light and / or for mixing differently colored light - individually are dimmable. This form of training also enables a temporal variation of both the light and color effects and the intensity of the emitted light for individual areas of the room. As a result, certain areas of the room can be illuminated more or less, and different color temperatures of the emitted light can be generated selectively or throughout the room and varied in time.
There is thus great freedom of design in the lighting of rooms through the various forms of training of the luminaire field according to the invention.
A particularly advantageous advantage of such luminaire fields is that, if required, they can be manufactured with a very low overall height, the overall height denoting the total thickness of the luminaire field normal to its carrier board. Favorable variants provide for the luminaire field to have an overall height of less than 3 to 4 cm, preferably less than 2 to 3 cm.
Further features and details of the present invention result from the following description of the figures. 1 shows a luminaire field with a reflector body according to the invention, FIG. 2 shows a reflector body with asymmetrical individual reflectors and FIG. 3 shows a reflector body with asymmetrical individual reflectors and different types of individual reflectors. FIG. 1 shows a section of a luminaire field according to the invention. Here 3 different LEDs 4 are applied to a carrier board and wired accordingly in the carrier board according to the prior art. The distribution of the LEDs 4 on the carrier board 3
<Desc / Clms Page number 3>
can be made uniformly as shown, but also arbitrarily non-uniformly. The control and dimming of the individual LEDs is carried out by a suitable control device 5.
According to the invention, a reflector body 1 is arranged in front of the carrier board 3. According to the invention, the reflector body 1 is preferably designed in one piece as an injection molded part. The reflector body 1 preferably has a corresponding one for paraboloidal individual reflectors 2 for each individual LED. For the sake of clarity, the carrier board 3 and the reflector body 1 are shown separately in FIG. 1. In the luminaire field according to the invention, however, the reflector body 1 is preferably fastened directly on the carrier board 3, so that the LEDs 4 extend into the recesses 6 of the individual reflectors assigned to them.
It is particularly expedient if the LEDs 4 are designed without vitreous bodies, but LEDs with vitreous bodies can also be used, for. B. can be used to produce color effects. In a favorable embodiment, it is provided that the LEDs 4 and / or the carrier board 3 and / or the individual reflectors 2 are of different colors and / or regions of different colors. This enables different color temperatures to be formed in different areas of the room illuminated by the light field. The dimming device 5 also makes it possible to change the various illuminance levels or color temperatures or color mixtures in addition to generating white light. The luminaire field can also be used on ceilings and walls as well as e.g. installed under glass in floors.
FIG. 2 shows one of many possible designs for the luminaire field according to the invention with asymmetrical and differently designed individual reflectors 2.
3 shows an embodiment variant with asymmetrical, symmetrical and various shapes having individual reflectors 2. In addition, it is also possible to vary other geometrical dimensions of the reflector body 1, such as, for example, varying its thickness or forming a curvature of its surfaces (not shown here) ,
