Definitions
- the present invention relates to a luminaire for illuminating a usable area, in particular a merchandise display area, with an adaptive lighting unit having a plurality of colored light emitting diodes which emit light in the primary colors of a color system, a directed to the effective area sensor, the one of the floor space and / or detected on the useful surface objects reflected light spectrum, and a control unit which is coupled to the sensor and configured to determine at least one dominant color from the sensed by the sensor reflected light spectrum and the LEDs to emphasize the at least one dominant color to control such that they emit a spectrum of light of predetermined color temperature and / or intensity in which the proportion of the at least one dominant color is enhanced.
- a lamp of this kind is from the US 2008/0258590 A1 known.
- the color of an object to be exhibited is recorded in a cube by means of a camera.
- the image is analyzed to capture the dominant color of the object, and based on this analysis, LEDs are driven so that the interior surfaces of the cube shine in the dominant color of the object.
- the prior art luminaire includes an adaptive illumination unit that emits light in the primary colors of a given color space or color system and can be individually driven by a control unit to emit a desired spectrum of light. Furthermore, a color light sensor is provided to detect a light spectrum of the ambient light, so that varying environmental conditions can be taken into account when driving the LED.
- an optical detection unit comprises a sensor system for producing a color image of an object located in a detection area, and an adaptive illumination unit which has a plurality of light color light sources controllable in the primary colors of a color system and is provided to introduce light with a predetermined color temperature and / or intensity into the detection area of the color system To radiate sensor technology.
- the control of the color light sources is carried out such that fluctuations in the color temperature and / or intensity of the scattered light in the vicinity of the detection range can be compensated.
- the light mood can be influenced with the familiar, light-colored and white-light-changeable LED lights. However, this has only a small influence on the change in the color saturation of product surfaces in order to achieve a sales-promoting effect of the lighting. Light color or light color changes are primarily visible on white surfaces and are perceived as a room climate, but they have little or no impact on product-related buying behavior.
- Retrofit LED luminaires are therefore used to illuminate goods and presentation surfaces, which, by combining colored and white LEDs, in part combined with phosphors, generate special spectra for food fresh product groups, such as meat and meat products, bakery products and fruit and vegetable products ( DE 20 2008 005 509 U1 ). All described solutions for the promotion of food fresh products are static solutions for individual product groups.

Die vorliegende Erfindung betrifft eine Leuchte zur Beleuchtung einer Nutzfläche, insbesondere einer Warenpräsentationsfläche, mit einer adaptiven Beleuchtungseinheit, die mehrere farbige Leuchtdioden aufweist, welche Licht in den Grundfarben eines Farbensystems emittieren, einer auf die Nutzfläche gerichteten Sensorik, die ein von der Nutzfläche und/oder auf der Nutzfläche liegenden Objekten reflektiertes Lichtspektrum erfasst, und einer Steuerungseinheit, die mit der Sensorik gekoppelt und ausgebildet ist, wenigstens eine dominierende Farbe aus dem von der Sensorik erfassten reflektierten Lichtspektrum zu bestimmen und die Leuchtdioden zur Betonung der wenigstens einen dominierenden Farbe derart anzusteuern, dass sie ein Lichtspektrum vorgegebener Farbtemperatur und/oder Intensität emittieren, in welchem der Anteil der wenigstens einen dominierenden Farbe verstärkt ist.The present invention relates to a luminaire for illuminating a usable area, in particular a merchandise display area, with an adaptive lighting unit having a plurality of colored light emitting diodes which emit light in the primary colors of a color system, a directed to the effective area sensor, the one of the floor space and / or detected on the useful surface objects reflected light spectrum, and a control unit which is coupled to the sensor and configured to determine at least one dominant color from the sensed by the sensor reflected light spectrum and the LEDs to emphasize the at least one dominant color to control such that they emit a spectrum of light of predetermined color temperature and / or intensity in which the proportion of the at least one dominant color is enhanced.

Mit den vorbekannten, lichtfarben und weißlichtfarben-veränderlichen LED-Leuchten lässt sich die Lichtstimmung beeinflussen. Diese hat aber nur einen geringen Einfluss auf die Veränderung der Farbsättigung von Produktoberflächen, um eine verkaufsfördernde Wirkung der Beleuchtung zu erzielen. Lichtfarben- bzw. Lichtfarbenveränderungen sind primär auf weißen Oberflächen sichtbar und werden als Raumklima wahrgenommen, sie beeinflussen das produktbezogene Kaufverhalten jedoch wenig oder gar nicht.The light mood can be influenced with the familiar, light-colored and white-light-changeable LED lights. However, this has only a small influence on the change in the color saturation of product surfaces in order to achieve a sales-promoting effect of the lighting. Light color or light color changes are primarily visible on white surfaces and are perceived as a room climate, but they have little or no impact on product-related buying behavior.
Zur Beleuchtung von Waren und Präsentationsflächen werden daher Retrofit-LED-Leuchten eingesetzt, die durch Kombination von farbigen und weißen LED zum Teil kombiniert mit Leuchtstoffen spezielle Spektren für Lebensmittelfrischeproduktgruppen wie beispielsweise Fleisch- und Fleischererzeugnisse, Backwaren sowie Obst- und Gemüsewaren erzeugen (
Aufgabe der vorliegenden Erfindung ist es, eine Leuchte der eingangs genannten Art so auszugestalten, dass sie universell zur Beleuchtung von Warenpräsentationsflächen unabhängig von der Art der darauf ausgestellten Produkte einsetzbar sind.Object of the present invention is to provide a lamp of the type mentioned in such a way that they can be used universally for the illumination of goods display areas regardless of the type of products issued thereon.
Diese Aufgabe wird erfindungsgemäß bei einer Leuchte der eingangs genannten Art dadurch gelöst, dass wenigstens ein Weißlichtspektrum als ein Standardlichtspektrum vorgegebener Farbtemperatur und/oder Intensität in der Steuerungseinheit gespeichert oder speicherbar ist, die Beleuchtungseinheit wenigstens eine Weißlicht-Leuchtiode aufweist, um Licht im weißen Spektralbereich zu emittieren, und die Steuerungseinheit die Weißlicht-Leuchtiode ansteuert, um das Weißlichtspektrum als Standardlichtspektrum zu emittieren, und zusätzlich die farbigen Leuchtioden ansteuert, um den Anteil der wenigstens einen dominierenden Farbe zu verstärken, wobei die Leuchtdioden derart angesteuert werden, dass das modifizierte Lichtspektrum ein maximales Intensitäts-Peak im roten Spektralbereich bei etwa 635 bis 650 nm und ein weiteres, minimales Intensitäts-Peak im grün/gelben Wellenlängenbereich bei 490 bis 560 nm, und schließlich ein mittleres Intensitäts-Peak im blauen Wellenlängenbereich bei etwa 440 bis 450 nm besitzt, wenn Rot die dominierende Farbe ist und entsprechend ein Weißlichtspektrum mit einem erhöhten Rotlichtanteil ermittelt werden soll, und/oder die Leuchtdioden derart angesteuert werden, dass das modifizierte Lichtspektrum ein maximales Intensitäts-Peak im roten Spektralbereich bei etwa 635 bis 650 nm, ein weiteres, mittleres Intensitäts-Peak im grün/gelben Wellenlängenbereich bei 495 bis 566 nm, und schließlich ein minimales Intensitäts-Peak im blauen Wellenlängenbereich bei etwa 440 bis 450 nm besitzt, wenn Gelb die dominierende Farbe ist und entsprechend ein Weißlichtspektrum mit einem erhöhten Grün/Gelb-Lichtanteil emittiert werden soll.This object is achieved in a luminaire of the type mentioned in that at least one white light spectrum is stored as a standard light spectrum predetermined color temperature and / or intensity in the control unit or storable, the lighting unit has at least one white light emitting diode to light in the white spectral range and the control unit drives the white light emitting diode to emit the white light spectrum as the standard light spectrum, and additionally drives the colored light emitting diodes to control the proportion of the at least one dominant light source Color, wherein the light emitting diodes are driven so that the modified light spectrum, a maximum intensity peak in the red spectral range at about 635 to 650 nm and another, minimum intensity peak in the green / yellow wavelength range at 490 to 560 nm, and finally has an average intensity peak in the blue wavelength range at about 440 to 450 nm, if red is the dominant color and a white light spectrum with an increased red light component is to be determined correspondingly, and / or the light-emitting diodes are controlled in such a way that the modified light spectrum has a maximum intensity Peak in the red spectral region at about 635-650 nm, another mid-intensity peak in the green / yellow wavelength region at 495-566 nm, and finally has a minimum intensity peak in the blue wavelength region at about 440-450 nm when yellow the dominant color is and correspondingly a white light spectrum m it is to be emitted with an increased green / yellow light component.
In der erfindungsgemäßen Leuchte ist somit ein Standard-lichtspektrum mit einer vorgegebenen Farbtemperatur und/oder -intensität in der Steuerungseinheit gespeichert oder speicherbar, mit welchem eine Warenpräsentationsfläche beleuchtet, d.h. erhellt werden soll. Bei diesem Standardlichtspektrum handelt es sich um ein Weißlichtspektrum.Thus, in the luminaire according to the invention, a standard light spectrum having a predetermined color temperature and / or intensity is stored or storable in the control unit with which a merchandise display surface is illuminated, i. should be illuminated. This standard light spectrum is a white light spectrum.
Über die Sensorik wird das Lichtspektrum erfasst, welches von der zu beleuchtenden Warenpräsentationsfläche und den darauf befindlichen Produkten reflektiert wird, und die dominierende Farbe in dem reflektierten Lichtspektrum bestimmt.The sensor system detects the light spectrum which is reflected by the product presentation surface to be illuminated and the products located thereon, and determines the dominant color in the reflected light spectrum.
Zur Betonung der wenigstens einen dominierenden Farbe wird dann das Standardlichtspektrum in der Weise modifiziert, dass der Anteil der wenigstens einen dominierenden Farbe in dem Standardlichtspektrum verstärkt und/oder der Anteil einer zu der wenigstens einen dominierenden Farbe entsprechenden Komplementärfarbe reduziert wird. Mit anderen Worten wird ein Lichtspektrum abgestrahlt, das einem gewünschten Standardlichtspektrum entspricht, aber in dem der Anteil der dominierenden Farbe verstärkt ist, um die Körperfarbe der auf der Warenpräsentationsfläche liegenden Produkte zu betonen.In order to emphasize the at least one dominant color, the standard light spectrum is then modified in such a way that the proportion of the at least one dominant color in the standard light spectrum is increased and / or the proportion of a complementary color corresponding to the at least one dominant color is reduced. In other words, a spectrum of light corresponding to a desired standard spectrum of light is emitted, but in which the dominant color portion is enhanced to emphasize the body color of the products placed on the merchandise display area.
Wenn beispielsweise Fleischwaren auf der Warenpräsentationsfläche positioniert sind, wird die Farbe Rot dominierend in dem reflektierten Lichtspektrum sein. In diesem Fall wird das Standardlichtspektrum durch Erhöhung des Rotlichtanteils modifiziert. Da es relativ häufig erforderlich ist, Fleischwaren zu beleuchten, ist gemäß einer Ausführungsform der Erfindung vorgesehen, dass ein Weißlichtspektrum mit einem erhöhten Rotlichtanteil in der Steuerungseinheit als modifiziertes Standardlichtspektrum gespeichert oder speicherbar ist und die Steuerungseinheit die Beleuchtungseinheit ansteuert, um dieses Lichtspektrum zu emittieren, wenn Rot als die dominierende Farbe in dem von der Sensorik erfassten reflektierten Lichtspektrum erkannt wird. Wird also ein erhöhter Rotlichtanteil in dem reflektierten Lichtspektrum festgestellt, wird automatisch dieses bereits vorgewählte Lichtspektrum ausgewählt und emittiert.For example, if meat products are positioned on the merchandise presentation surface, the color red will be dominant in the reflected light spectrum. In this case, the standard light spectrum is modified by increasing the proportion of red light. Since it is relatively often necessary to illuminate meat products, it is provided according to an embodiment of the invention that a white light spectrum with an increased proportion of red light in the control unit is stored or storable as a modified standard light spectrum and the control unit controls the lighting unit to emit this light spectrum, if Red as the dominant color is detected in the reflected light spectrum detected by the sensor. If, therefore, an increased proportion of red light is detected in the reflected light spectrum, this already preselected light spectrum is automatically selected and emitted.
Alternativ und/oder zusätzlich kann ein Weißlichtspektrum mit einem erhöhten Grün/Gelb-Lichtanteil in der Steuerungseinheit gespeichert oder speicherbar sein, wobei dann die Steuerungseinheit die Belichtungseinheit ansteuert, um dieses Lichtspektrum zu emittieren, wenn Gelb als die dominierende Farbe aus dem von der Sensorik erfassten reflektierten Lichtspektrums bestimmt wird. Dies ist beispielsweise der Fall, wenn Backwaren beleuchtet werden.Alternatively and / or additionally, a white light spectrum with an increased green / yellow light component can be stored or storable in the control unit, in which case the control unit controls the exposure unit to emit this light spectrum, if yellow is the dominant color from that detected by the sensor system reflected light spectrum is determined. This is the case, for example, when baked goods are illuminated.
Gemäß der vorliegenden Erfindung weist die Beleuchtungseinheit wenigstens eine Weißlicht-Leuchtdiode auf, um Licht im weißen Spektralbereich zu emittieren, und ist ein Weißlichtspektrum als Standardlichtspektrum in der Steuerungseinheit gespeichert. Die Steuerungseinheit steuert dann die Weißlicht-Leuchtdiode an, um das Weißlichtspektrum als Standardlichtspektrum zu emittieren, und zusätzlich die farbigen Leuchtdioden an, um den Anteil der wenigstens einen dominierenden Farbe zu verstärken. Mit anderen Worten wird dem Weißlichtspektrum, welches der Weißlicht-Leuchtdiode emittiert, von einem Lichtspektrum, welches durch die farbigen Leuchtdioden erzeugt wird, überlagert. Wenn beispielsweise die Farbe Rot betont werden soll, wird die Steuerungseinheit die Weißlicht-Leuchtdiode ansteuern, um das Weißlichtspektrum als Standardlichtspektrum zu emittieren. Zusätzlich werden die roten, grünen und blauen LED des sogenannten RGB-Farbraums derart angesteuert, dass das modifizierte Lichtspektrum, welches sich durch Überlagerung der von den farbigen Leuchtdioden und der Weißlicht-Leuchtdiode emittierten Lichtspektren ergibt, ein Weißlichtspektrum mit erhöhtem Rotlichtanteil ist. Erfindungsgemäß werden die Leuchtdioden derart angesteuert, dass das modifizierte Lichtspektrum ein maximales Intensitäts-Peak im roten Spektralbereich bei etwa 635 bis 650 nm, ein weiteres, minimales Intensitäts-Peak im grün/gelben Wellenlängenbereich bei 495 bis 566 nm, und schließlich ein mittleres Intensitäts-Peak im blauen Wellenlängenbereich bei etwa 440 bis 450 nm besitzt. Insbesondere erfolgt die Ansteuerung der Leuchtdioden derart, dass unter der Annahme, dass die maximale normierte Intensität im roten Spektralbereich 100% beträgt, das Intensitäts-Peak im grünen/gelben Wellenlängenbereich bei 15 bis 20% und insbesondere 17% liegt und das Intensitäts-Peak im blauen Wellenlängenbereich bei etwa 20 bis 25%, insbesondere bei etwa 22% liegt.According to the present invention, the illumination unit has at least one white light emitting diode to emit light in the white spectral range, and a white light spectrum is stored as a standard light spectrum in the control unit. The control unit then drives the white light emitting diode to emit the white light spectrum as the standard light spectrum, and additionally the colored light emitting diodes to enhance the proportion of the at least one dominant color. In other words, the white light spectrum emitted by the white light emitting diode is superposed by a light spectrum generated by the colored light emitting diodes. For example, if the color red is to be emphasized, the control unit will drive the white light emitting diode to emit the white light spectrum as the standard light spectrum. In addition, the red, green and blue LEDs of the so-called RGB color space are controlled in such a way that the modified light spectrum, which results from the superposition of the light spectra emitted by the colored light-emitting diodes and the white-light LED, is a white-light spectrum with an increased proportion of red light. According to the invention, the light-emitting diodes are driven in such a way that that the modified light spectrum is a maximum intensity peak in the red spectral range at about 635 to 650 nm, another minimum intensity peak in the green / yellow wavelength range at 495 to 566 nm, and finally an average intensity peak in the blue wavelength range at about 440 up to 450 nm. In particular, the activation of the light-emitting diodes takes place such that, assuming that the maximum normalized intensity in the red spectral region is 100%, the intensity peak in the green / yellow wavelength range is 15 to 20% and in particular 17%, and the intensity peak is blue wavelength range is about 20 to 25%, in particular about 22%.
Wenn Backwaren beleuchtet werden und damit der grün/gelbe Wellenlängenbereich zu betonen ist, wird die Steuerungseinheit die Weißlicht-Leuchtdioden und die farbigen LED derart ansteuern, dass ein Weißlichtspektrum mit einem erhöhen grün/gelben Lichtanteil emittiert wird. In diesem Fall werden die Leuchtdioden derart angesteuert, dass , dass das modifizierte Lichtspektrum ein maximales Intensitäts-Peak im roten Spektralbereich bei etwa 635 bis 650 nm, ein weiteres, mittleres Intensitäts-Peak im grün/gelben Wellenlängenbereich bei 495 bis 566 nm, und schließlich ein minimales Intensitäts-Peak im blauen Wellenlängenbereich bei etwa 440 bis 450 nm besitzt. Insbesondere werden die Leuchtdioden derart angesteuert, dass die Leuchtdioden derart angesteuert werden, dass unter der Annahme, dass die maximale normierte Intensität im roten Spektralbereich 100% beträgt, das Intensitäts-Peak im grün/gelben Wellenlängenbereich bei 35 bis 45% und insbesondere 40% liegt und das Intensitäts-Peak im blauen Wellenlängenbereich bei etwa 20 bis 25%, insbesondere bei etwa 22% liegt.If baked goods are illuminated and the green / yellow wavelength range is to be emphasized, the control unit will control the white light LEDs and the colored LEDs in such a way that a white light spectrum with an increased green / yellow light component is emitted. In this case, the light-emitting diodes are driven so that the modified light spectrum is a maximum intensity peak in the red spectral range at about 635 to 650 nm, another, average intensity peak in the green / yellow wavelength range at 495 to 566 nm, and finally has a minimum intensity peak in the blue wavelength range at about 440 to 450 nm. In particular, the light-emitting diodes are controlled in such a way that the light-emitting diodes are controlled such that, assuming that the maximum normalized intensity in the red spectral range is 100%, the intensity peak in the green / yellow wavelength range is 35 to 45% and in particular 40% and the Intensity peak in the blue wavelength range is about 20 to 25%, in particular about 22%.

Mit anderen Worten wird zur Bestimmung der dominierenden Farbe ein Erfassungsmodus angewählt, in dem die Beleuchtungseinheit ein Erfassungs-Lichtspektrum emittiert. Bei diesem Erfassungs-Lichtspektrum kann es sich um das gespeicherte Standard-Lichtspektrum handeln. Der Erfassungsmodus wird vorzugsweise automatisch zu vorgegebenen Zeitpunkten, insbesondere nach dem Einschalten der Leuchte und/oder während des Betriebes in vorgegebenen Zeitintervallen angewählt. Eine manuelle Aktivierung kann ebenfalls möglich sein.In a further embodiment of the present invention, it is provided that the control unit has a detection mode in which the illumination unit and the sensor system are controlled such that the illumination unit emits a detection light spectrum and the sensors emit the objects lying on the usable area and / or on the usable area reflected light spectrum detected to determine the dominant color in the reflected light spectrum.

This detection light spectrum may be the stored standard light spectrum. The detection mode is preferably selected automatically at predetermined times, in particular after switching on the lamp and / or during operation at predetermined time intervals. Manual activation may also be possible.
