Description

Beleuchtung mit LED  Lighting with LED

Die Erfindung betrifft ein Leuchtmittel mit Leuchtdioden gemäß dem The invention relates to a light emitting diode with light-emitting diodes according to the

Oberbegriff des Patentanspruchs 1. Preamble of claim 1.

Technisches Gebiet Technical area

Derartige Leuchtmittel werden in Beleuchtungssystemen verwendet, um eine flächige Beleuchtung von Räumen, Wegen oder auch Fluchtwegen zu erreichen. Üblicherweise werden dabei die Leuchtmittel von Betriebsgeräten angesteuert und bei Bedarf aktiviert. Für eine derartige Beleuchtung werden Gasentladungslampen oder auch Leuchtdioden (LED) als Lichtquelle genutzt. Such lamps are used in lighting systems to achieve a flat lighting of rooms, paths or escape routes. Usually, the bulbs are driven by operating devices and activated as needed. For such lighting gas discharge lamps or light emitting diodes (LED) are used as the light source.

Stand der Technik State of the art

Zur Beleuchtung werden anstelle von Gasentladungslampen und Glühlampen immer häufiger auch Leuchtdioden als Lichtquelle eingesetzt. Die Effizienz und Lichtausbeute von Leuchtdioden wird immer stärker erhöht, so dass sie bei verschiedenen Anwendungen der Allgemeinbeleuchtung bereits zum Einsatz kommen. Allerdings sind Leuchtdioden Punktlichtquellen und strahlen stark gebündeltes Licht aus. In der Allgemeinbeleuchtung, beispielsweise von Büroräumen oder auch bei Wegbeleuchtungen oder der Beleuchtung von Treppenhäusern, wird vom Anwender jedoch eine möglichst flächige und gleichmäßige Beleuchtung gefordert. For lighting, instead of gas discharge lamps and incandescent lamps, light-emitting diodes are also increasingly being used as the light source. The efficiency and luminous efficacy of light-emitting diodes is being increased more and more so that they are already being used in various general lighting applications. However, light emitting diodes are point sources of light and emit highly concentrated light. In general lighting, for example, in offices or even with path lighting or the lighting of staircases, however, the user is required a surface as even and uniform lighting.

Heutige Leuchtmittel mit Leuchtdioden als Lichtquelle versuchen daher mit Hilfe einer sogenannten Sekundäroptik, d.h. einer Linse oder Streuscheibe, die über einer oder mehreren Leuchtdioden angebracht ist, eine möglichst großflächige Lichtabstrahlung zu erzielen. Today's light sources with light emitting diodes as the light source therefore try by means of a so-called secondary optics, i. a lens or diffuser, which is mounted over one or more light-emitting diodes, to achieve the widest possible light emission.

Eine Beleuchtung ohne Beeinträchtigung von Tieren als Lebewesen wie beispielsweise Insekten ist bei LED heutzutage noch nicht möglich. Darstellung der Erfindung Lighting without affecting animals as living things such as insects is not yet possible with LEDs today. Presentation of the invention

Es ist die Aufgabe der Erfindung, ein Leuchtmittel bereitzustellen, welches eine Beleuchtung ohne Beeinträchtigung von Tieren als Lebewesen wie beispielsweise Insekten und mit hoher Leuchtkraft durch ein Leuchtmittel mit einer LED ohne die oben genannten Nachteile bzw. unter einer deutlichen Reduzierung dieser Nachteile ermöglicht. Diese Aufgabe wird für eine gattungsgemäße Vorrichtung erfindungsgemäß durch die kennzeichnenden Merkmale des Patentanspruchs 1 gelöst. It is the object of the invention to provide a light source, which allows lighting without affecting animals as living beings such as insects and with high luminosity by a light source with an LED without the above-mentioned disadvantages or with a significant reduction of these disadvantages. This object is achieved according to the invention for a generic device by the characterizing features of claim 1.

Besonders vorteilhafte Ausführungen der Erfindung sind in den Particularly advantageous embodiments of the invention are in the

Unteransprüchen beschrieben. Die erfindungsgemäße Lösung für ein Leuchtmittel mit Leuchtdioden beruht auf dem Gedanken, dass das Subclaims described. The solution according to the invention for a light-emitting diode with light-emitting diodes is based on the idea that the

Leuchtmittel mit mindestens einer ersten Leuchtdiode, die Licht im blauen bis ultravioletten Bereich ausstrahlt,  Illuminant with at least one first light emitting diode that emits light in the blue to ultraviolet range,

einen ersten Farbkonversationsstoff aufweist, der zumindest einen Teil des von der Leuchtdiode ausgestrahlten Lichtes in ein licht mit höherer a first Farbkonversationsstoff having at least a portion of the light emitted by the light emitting diode in a light with higher

Wellenlänge umwandelt, wobei der erste Farbkonversationsstoff zumindest einen Teilbereich des im blauen bis ultravioletten Bereich ausstrahlten Lichts soweit in Licht einer anderen Wellenlänge umwandelt oder absorbiert, so dass Licht ohne eine Beeinträchtigung von Lebewesen ausgestrahlt wird.  Wavelength converts, wherein the first color conversion substance at least a portion of the light emitted in the blue to ultraviolet range light converted or absorbed so far in light of a different wavelength, so that light is emitted without impairment of living beings.

Auf diese Weise ist es möglich, eine Beleuchtung ohne eine Beeinträchtigung von Lebewesen zu erreichen. In this way it is possible to achieve illumination without affecting living beings.

Beschreibung der bevorzugten Ausführungsbeispiele Description of the preferred embodiments

Nachfolgend wird die Erfindung anhand eines Ausführungsbeispiels eines Leuchtmittels mit Leuchtdioden erklärt. Das Leuchtmittel weist folgende Elemente auf: The invention will be explained with reference to an embodiment of a light emitting diode with LEDs. The light source has the following elements:

mindestens eine ersten Leuchtdiode, die Licht im blauen bis ultravioletten Bereich ausstrahlt,  at least one first light emitting diode that emits light in the blue to ultraviolet range,

einen ersten Farbkonversationsstoff, der zumindest einen Teil des von der Leuchtdiode ausgestrahlten Lichtes in ein licht mit höherer Wellenlänge umwandelt, wobei der erste Farbkonversationsstoff zumindest einen a first color conversion material that converts at least a portion of the light emitted by the light emitting diode into a light having a higher wavelength, wherein the first color conversion material has at least one

Teilbereich des im blauen bis ultravioletten Bereich ausstrahlten Lichts soweit in Licht einer anderen Wellenlänge umwandelt oder absorbiert, so dass Licht ohne eine Beeinträchtigung von Lebewesen ausgestrahlt wird. Part of the light emitted in the blue to ultraviolet range converted or absorbed light of a different wavelength, so that light is emitted without affecting living beings.

Die Umwandlung des Lichts in dem Teilbereich des Lichtes im blauen bis ultravioletten Bereich kann selektiv erfolgen. Die selektive Wahl der Umwandlung kann beispielsweise über die Auswahl der chemischen Zusammensetzung des Farbkonversationsstoffs erfolgen The conversion of the light in the partial region of the light in the blue to ultraviolet range can be selective. The selective choice of the conversion can be made, for example, by selecting the chemical composition of the color conversion substance

(beispielsweise unterschiedliche Dotierung oder entsprechende Mischung verschiedener Farbkonversationsstoffe), es kann aber beispielsweise auch eine elektronische Beeinflussung des Farbkonversationsstoffs erfolgen, wodurch dieser in seiner Umwandlungscharakteristik beeinflusst werden kann. (For example, different doping or appropriate mixture of different color conversion materials), but it can also be done, for example, an electronic influence of the color conversion substance, whereby this can be influenced in its conversion characteristics.

Es erfolgt also gemäß der Erfindung eine selektive Unterdrückung einer Lichtabstrahlung in definierten Wellenlängenbereichen, wobei diese Thus, according to the invention, a selective suppression of light emission takes place in defined wavelength ranges, wherein these

Wellenlängenbereiche durch die Wahl eines oder mehrerer entsprechender Farbkonversationsstoffe gewählt werden können. Somit kann eine Wavelength ranges can be selected by the choice of one or more corresponding color conversion materials. Thus, a

Beeinträchtigung von Lebewesen wie beispielsweise Insekten verhindert oder zumindest stark eingeschränkt werden.  Impairment of living things such as insects are prevented or at least severely restricted.

Das Leuchtmittel kann weitere Leuchtdioden aufweisen, die Licht in einem Wellenlängenbereich ausstrahlen, wobei das Licht der weiteren Leuchtdioden nicht von dem ersten Farbkonversationsstoff umgewandelt oder absorbiert wird. Das Leuchtmittel kann einen weiteren Farbkonversationsstoff enthalten, der das Licht der weiteren Leuchtdioden in Licht einer anderen Wellenlänge umwandelt. Vorzugsweise unterscheidet sich dabei die Wellenlänge des Lichts, welches durch Umwandlung des Lichtes der weiteren Leuchtdioden mittels des weiteren Farbkonversationsstoffs abgestrahlt wird, von der The lighting means may comprise further light-emitting diodes which emit light in a wavelength range, wherein the light of the further light-emitting diodes is not converted or absorbed by the first color-conversing substance. The luminous means may contain a further color-conversing substance which converts the light of the further light-emitting diodes into light of a different wavelength. Preferably, the wavelength of the light, which is emitted by the conversion of the light of the further light-emitting diodes by means of the further color-conversing substance, differs from that of FIG

Wellenlänge des mittels der ersten Leuchtdioden und des ersten Wavelength of the means of the first light emitting diodes and the first

Farbkonversationsstoffs abgestrahlten Lichts.  Color Conversation Material of radiated light.

Die verschiedenen Leuchtdioden können selektiv und unabhängig voneinander ansteuerbar sein. The different LEDs can be selectively and independently controlled.

Somit kann beispielsweise eine Straßenbeleuchtung errichtet und betrieben werden, wobei das Licht ohne eine Beeinträchtigung von Insekten ausgestrahlt wird. Durch die Mischung des Lichts aus zumindest zwei verschiedenen Farben von Leuchtdioden und zusätzlich zwei verschiedene Thus, for example, a street lighting can be built and operated, the light being radiated without interference from insects. By mixing the light from at least two different colors of light emitting diodes and additionally two different ones

Farbkonversationsstoffe kann aber auch zusätzlich eine Beleuchtung mit Wellenlängenbereichen ermöglicht werden, die bestimmte Lebewesen gezielt entweder anziehen oder abschrecken. So kann beispielsweise durch die Beleuchtung mit dem erfindungsgemäßen Leuchtmittel bestimmte Tiere (beispielsweise Rehe) abgeschreckt und somit beispielsweise von einer However, color conversing materials can also be provided with illumination with wavelength ranges which selectively attract or deter certain living beings. Thus, for example, by the illumination with the illuminant according to the invention certain animals (for example deer) quenched and thus, for example, from a

Strasse ferngehalten werden, während andere Lebewesen wie Insekten oder Pflanzen nicht durch diese Beleuchtung beeinträchtigt oder irritiert werden. Somit kann beispielsweise für eine Strassenbeleuchtung der negative Einfluß der künstlichen Beleuchtung auf die Natur dahingehend verringert werden, dass die Lebewesen in ihrem Lebensraum möglichst wenig durch die künstliche Beleuchtung beeinträchtigt werden, wobei dabei sogar zusätzlich positive Effekte wie die Vermeidung von Wildunfällen genutzt werden können. Es kann aber auch eine Kombination genutzt werden, bei der beispielsweise bestimmte Lebewesen wie Nutzpflanzen in ihrem Wachstum gefördert werden, während Schädlinge durch die Beleuchtung abgeschreckt und somit ferngehalten werden. Für das Leuchtmittel können durch die selektive Ansteuerung der einzelnen Leuchtdioden verschiedene Beleuchtungsszenarien erreicht werden. Street are kept away, while other living things such as insects or plants are not affected or irritated by this lighting. Thus, for example, for a street lighting, the negative influence of artificial lighting on nature can be reduced to the extent that the living beings in their habitat are affected as little as possible by the artificial lighting, while even positive effects such as the prevention of wildlife accidents can be used. But it can also be used a combination in which, for example, certain organisms such as crops are promoted in their growth, while pests are quenched by the lighting and thus kept away. For the light source can be achieved by the selective control of the individual LEDs different lighting scenarios.

Die Leuchtdioden können als sogenannte SMD (surface mount device) oder COB (chip on board) Leuchtdioden gefertigt werden. Der The light-emitting diodes can be manufactured as so-called SMD (surface mount device) or COB (chip on board) light-emitting diodes. Of the

Farbkonversationsstoff kann direkt über dem Halbleiterchip aufgebracht werden oder auch als sekundäre Optik über einer Mehrzahl von Leuchtdioden angeordnet sein, beispielsweise in Form einer mit dem Farbkonversationsstoff beschichteten Scheibe, die im Lichtaustrittsbereich des Leuchtmittels (also über der Leuchtdiodenanordnung beispielsweise im Lichtaustrittsbereich der Leuchte) angeordnet ist. Es kann also beispielsweise eine gemeinsame Linse oder ähnliche Optik bzw. Abdeckung über den Leuchtdioden angebracht sein.  Color conversion material can be applied directly over the semiconductor chip or can also be arranged as secondary optics over a plurality of light-emitting diodes, for example in the form of a pane coated with the color conversion substance, which is arranged in the light exit region of the light source (ie above the light-emitting diode arrangement, for example in the light exit region of the light). It can therefore be mounted, for example, a common lens or similar optics or cover over the light emitting diodes.

Somit kann eine Effektbeleuchtung, beispielsweise eine Werbebeleuchtung oder beleuchtete Werbetafel, aufweisend ein erfindungsgemäßes Leuchtmittel gebildet werden. Thus, an effect lighting, such as an advertising lighting or illuminated billboard, comprising an inventive lighting means can be formed.
