Description

Die Erfindung betrifft eine Not- und/oder Sicherheitsbeleuchtungsanlage mit mindestens einer Leuchte, insbesondere Not- und/oder Sicherheitsleuchte, die mindestens ein Leuchtmittel zur Abgabe eines optisch, insbesondere visuell, erfassbaren Blinkmusters aufweist, und mit einem Gerät zur optischen Erfassung des Blinkmusters, wobei das Gerät eine optoelektronische Einrichtungmit einem Photodetektor und mit einem Objektiv aufweist.The invention relates to an emergency and / or safety lighting system with at least one light, in particular emergency and / or safety light, which has at least one light source for emitting an optically, in particular visually, detectable blinking pattern, and with a device for optically detecting the blinking pattern, wherein the device has an optoelectronic device with a photodetector and with an objective.

Bei einer Not- und/oder Sicherheitsbeleuchtungsanlage ist bekannt, eine Datenkommunikation zwischen deren Leuchten und einem Gerät zur optischen Erfassung des Blinkmusters, nämlich einem Mobiltelefon, herzustellen ( WO2017/138029A1 ). Hierzu gibt die Leuchte ein Blinkmuster ab, das von der Kamera des Mobiltelefons erfasst wird. Solch eine Kamera weist als optoelektronische Einrichtung meist CCD-Sensoren oder CMOS-Sensoren als Photodetektor auf, die jedoch nachteilig beim optischen Erfassen eines Blinkmusters von einer vergleichsweise weit entfernten Leuchte in Sättigung durch Umgebungslicht geraten können. Zudem sind derartige Sensoren mit einer vergleichsweise hohen Bildauflösung versehen, was zwar für eine Schärfentiefe vorteilhaft ist, die Isolation einer Blinkmuster abgebenden Lampe vor einem Hintergrund aber erschwert.In the case of an emergency and / or safety lighting system, it is known to establish data communication between its lights and a device for optical detection of the blinking pattern, namely a mobile phone ( WO2017 / 138029A1 ). To do this, the light emits a flashing pattern that is recorded by the cell phone's camera. Such a camera usually has CCD sensors or CMOS sensors as photodetectors as optoelectronic devices, which can, however, disadvantageously become saturated by ambient light when optically detecting a blinking pattern from a comparatively distant lamp. In addition, such sensors are provided with a comparatively high image resolution, which is advantageous for a depth of field, but makes it difficult to isolate a lamp emitting blinking patterns from a background.

Die Erfindung hat sich daher die Aufgabe gestellt, ein Gerät zur optischen Erfassung eines Blinkmusters derart zu verändern, dass mit diesem - unabhängig von der Position einer Leuchte einer Not- und/oder Sicherheitsbeleuchtungsanlage - das Blinkmuster der Leuchte standfest erfasst werden kann. Zudem soll das Gerät besonders handhabungsfreundlich sein.The invention has therefore set itself the task of modifying a device for optically detecting a blinking pattern in such a way that the blinking pattern of the luminaire can be steadily detected with it - regardless of the position of a light of an emergency and / or safety lighting system. In addition, the device should be particularly easy to use.

Die Erfindung löst die gestellte Aufgabe durch die Merkmale des Anspruchs 1.The invention solves the problem posed by the features of claim 1.

Indem eine Photodiode, insbesondere PIN-Photodiode, den Photodetektor ausbildet, kann das Gerät besonders robust gegenüber Umgebungslicht ausgebildet werden, wenn ein Blinkmuster von einer Leuchte optisch zu erfassen ist. Gegenüber Bildsensoren kann sich die Photodiode als Lichtsensor aber auch durch ein vergleichsweise günstiges Zeitverhalten auszeichnen - was einer Sensor-Sättigung durch Flickern und/oder Flimmern anderer Beleuchtungsmittel entgegenwirkt. Dies ist insbesondere bei der Erfassung von räumlich weiter entfernten Leuchten von Vorteil, bei denen bei der optischen Erfassung ihrer Blinkmuster mit mehr Umgebungslicht zu rechnen ist. Durch die Verwendung einer Photodiode als Bauteil der optoelektronische Einrichtung des Geräts kann ein Blinkmuster einer Leuchte einer Not- und/oder Sicherheitsbeleuchtungsanlage also zuverlässig optisch erfasst werden, dies insbesondere auch unabhängig von deren Position, was auch die Handhabung des Geräts erleichtern kann.Since a photodiode, in particular a PIN photodiode, forms the photodetector, the device can be made particularly robust with respect to ambient light when a blinking pattern is to be optically detected by a lamp. Compared to image sensors, the photodiode as a light sensor can also be distinguished by a comparatively favorable time behavior - which counteracts sensor saturation due to flicker and / or flicker of other lighting means. This is particularly advantageous when detecting luminaires that are spatially further away, where more ambient light is to be expected when their blinking patterns are optically detected. By using a photodiode as a component of the optoelectronic device of the device, a flashing pattern of a lamp of an emergency and / or safety lighting system can thus be reliably optically detected, in particular regardless of its position, which can also facilitate the handling of the device.

Die Standfestigkeit in der optischen Erfassung des Blinkmusters kann erhöht werden, wenn die Photodiode eine Sensorfläche von 4 bis 9 mm2, insbesondere von 2,73 x 2,73 mm, aufweist.The stability in the optical detection of the blink pattern can be increased if the photodiode has a sensor area of 4 to 9 mm 2 , in particular 2.73 × 2.73 mm.

Vorzugsweise ist das Objektiv als Teleobjektiv ausgebildet, um die optische Erfassung von Umgebungslicht einzuschränken - was insbesondere bei vergleichsweise weit entfernten Leuchten verstärkt der Fall sein kann.The lens is preferably designed as a telephoto lens in order to restrict the optical detection of ambient light - which can be the case in particular with lamps that are comparatively far away.

Die optoelektronische Einrichtung weist einen Bildwinkel im Bereich von 0,6 bis 28 Grad auf, um damit Blinkmuster unterschiedlich angeordneter Leuchten einer Not- und/oder Sicherheitsbeleuchtungsanlage robust erfassten zu können. Insbesondere ein Bildwinkel im Bereich von 4 bis 7 Grad, vorzugsweise 5,7 Grad, führt zu einem hinsichtlich der Handhabungsfreundlichket verbesserten Gerät für ein entfernungsunabhängiges Erfassen eines Blinkmusters.The optoelectronic device has an angle of view in the range from 0.6 to 28 degrees in order to be able to robustly detect flashing patterns of differently arranged lights of an emergency and / or safety lighting system. In particular, an angle of view in the range from 4 to 7 degrees, preferably 5.7 degrees, leads to a device that is improved in terms of ease of use for a distance-independent detection of a blinking pattern.

Der Eintrag von Umgebungslicht ist weiter reduzierbar, wenn die optoelektronische Einrichtung eine dem Objektiv vorgeschaltete Streulichtblende aufweist. Damit ist die Standfestigkeit des Geräts weiter zu erhöhen.The entry of ambient light can be further reduced if the optoelectronic device has a lens hood upstream of the lens. This further increases the stability of the device.

Die Erfassung eines Blinkmusters - auch bei vergleichsweise weit entfernten Leuchten - kann weiter erleichtert werden, wenn das Gerät eine Laserstrahlquelle aufweist, deren Laserstrahl zur optischen Achse des Objektivs hin geneigt verläuft.The detection of a flashing pattern - even with lights that are comparatively far away - can be further facilitated if the device has a laser beam source whose laser beam is inclined towards the optical axis of the lens.

Konstruktive Einfachheit kann erreicht werden, wenn das Gerät ein Rohr aufweist, das den Photodetektor und das Objektiv aufnimmt und die Streulichtblende ausbildet. Des Weiteren ist damit die Robustheit des Geräts weiter erhöhbar.Constructive simplicity can be achieved if the device has a tube that receives the photodetector and the lens and forms the lens hood. Furthermore, the robustness of the device can thus be further increased.

Vorzugsweise ist die Innenseite des Rohrs schwarz gefärbt, um Reflexionen an der optoelektronischen Einrichtung zu reduzieren und die Standfestigkeit des Geräts weiter zu erhöhen.The inside of the tube is preferably colored black in order to reduce reflections on the optoelectronic device and to further increase the stability of the device.

Weist das Gerät ein Griffteil auf, an welches das Rohr gegenüber der Längsachse des Griffteils abgewinkelt anschließt, ist der Handhabung des Geräts weiter zu erleichtern.If the device has a handle part to which the tube is connected at an angle with respect to the longitudinal axis of the handle part, the handling of the device is further facilitated.

Vorzugsweise weist das Griffteil eine Batterie zur elektrischen Versorgung des Geräts auf, um damit beispielsweise hohe Standzeiten bei der Erfassung von Blinkmustern sicherzustellen.The handle part preferably has a battery for the electrical supply of the device in order, for example, to ensure a long service life when detecting blinking patterns.

Das Objektiv kann eine, insbesondere im Rohr gehaltene, Sammellinse aufweisen, deren Brennpunkt auf der Sensorfläche des Photodetektors liegt, um damit eine vergleichsweise hohe Empfindlichkeit des Geräts bei der Erfassung eines Blinkmusters sicherzustellen.The objective can have a converging lens, in particular held in the tube, the focal point of which lies on the sensor surface of the photodetector, in order to ensure a comparatively high sensitivity of the device when detecting a blinking pattern.

Vorzugsweise weist das Gerät ein Vibrationselement zur haptischen Bestätigung des vom Gerät erfassten Blinkmusters auf, um die Handhabung des Geräts weiter zu verbessern.The device preferably has a vibration element for haptic confirmation of the blinking pattern detected by the device in order to further improve the handling of the device.

Vorzugsweise unterscheiden sich die Blinkmuster der mindestens zwei Leuchten der Not- und/oder Sicherheitsbeleuchtungsanlage voneinander. Damit ist das Blinkmuster der jeweiligen Leuchte eindeutig, was die optische Erfassung durch das Gerät erleichtern kann.The flashing patterns of the at least two lights of the emergency and / or safety lighting system preferably differ from one another. This means that the flashing pattern of the respective lamp is clear, which can facilitate optical detection by the device.

Vorzugsweise weist die Not- und/oder Sicherheitsbeleuchtungsanlage eine Zentrale auf, wobei die Leuchte und/oder das Gerät mit der Zentrale verbunden ist. Hierzu kann sich eine drahtlose und/oder drahtgebundene Datenverbindung besonders eignen.The emergency and / or safety lighting system preferably has a control center, the lamp and / or the device being connected to the control center. A wireless and / or wired data connection can be particularly suitable for this purpose.

In den Figuren ist beispielsweise der Erfindungsgegenstand anhand einer Ausführungsvariante näher dargestellt. Es zeigen

a schematic view of an emergency and safety lighting system and
Fig. 2
a detailed view of the Fig. 1 .

Nach Fig. 1 ist eine Not- und Sicherheitsbeleuchtungsanlage 1 (bzw. Notbeleuchtungs- und Sicherheitsbeleuchtungsanlage) mit mehreren, im Ausführungsbeispiel zwei, Leuchten 2a, 2b, nämlich Not- und Sicherheitsleuchten, und mit einem Gerät 3 zur optischen, visuellen Erfassung eines Blinkmusters 4a, 4b dargestellt.To Fig. 1 shows an emergency and safety lighting system 1 (or emergency lighting and safety lighting system) with several, in the exemplary embodiment two, lights 2a, 2b, namely emergency and safety lights, and with a device 3 for optical, visual detection of a flashing pattern 4a, 4b.

Dieses Blinkmuster 4a, 4b wird von den Not- und Sicherheitsleuchten 2a, 2b abgegeben. Die jeweiligen Blinkmuster 4a, 4b der Leuchten 2a, 2b können sich voneinander unterscheiden. Somit liegt eine Eindeutigkeit vor, was eine gleichzeitige Abgabe der Blinkmuster 4a, 4b beispielsweise bei der Initialisierung einer Not- und/oder Sicherheitsbeleuchtungsanlage 1 ermöglichen kann. Die Leuchten 2a, 2b sind beispielsweise über eine drahtgebundene Datenverbindung 6 mit eine Zentrale 7 der Not- und/oder Sicherheitsbeleuchtungsanlage 1 verbunden.This flashing pattern 4a, 4b is emitted by the emergency and safety lights 2a, 2b. The respective flashing patterns 4a, 4b of the lights 2a, 2b can differ from one another. It is therefore clear what a simultaneous output of the flashing patterns 4a, 4b can enable, for example during the initialization of an emergency and / or safety lighting system 1. The lights 2a, 2b are for example connected to a control center 7 of the emergency and / or safety lighting system 1 via a wired data connection 6.

Zur Abgabe des Blinkmusters 4a, 4b weisen die Leuchten 2a, 2b Leuchtmittel 5a, 5b, beispielsweise in Form wenigstens eines LED, auf. Vorzugsweise finden diese Leuchtmittel 5a, 5b Verwendung zur Beleuchtung oder Hinterleuchtung einer Anzeige 8a, 8b der Leuchten 2a, 2b und/oder zur Beleuchtung von Rettungswegen.To emit the blink pattern 4a, 4b, the lights 2a, 2b have lighting means 5a, 5b, for example in the form of at least one LED. These illuminants 5a, 5b are preferably used to illuminate or backlight a display 8a, 8b of the lamps 2a, 2b and / or to illuminate escape routes.

Das Gerät 3 zur optischen Erfassung eines Blinkmusters 4a der Blinkmuster 4a, 4b weist eine optoelektronische Einrichtung 9 mit einem Photodetektor 10 und mit einem Objektiv 11 auf.The device 3 for optically detecting a blinking pattern 4a of the blinking patterns 4a, 4b has an optoelectronic device 9 with a photodetector 10 and with an objective 11.

Jenes bei der optischen Erfassung des Blinkmusters 4a der Leuchte 2a einstreuende Umgebungslicht, was auch ein Blinkmuster 4b einer anderen Leuchte 2b, natürliches Sonnenlicht, Flickern und/oder Flackern und/oder Flimmern anderer, nicht dargestellter Leuchten, etc. umfassen kann, kann das Gerät 3 in der Funktion nicht beeinträchtigen, weil dieses erfindungsgemäß eine in Form eines Bauteils ausgebildete Photodiode 10a, nämlich eine PIN-Photodiode ("positive intrinsic negative diode"), als Photodetektor 10 aufweist - wie in Fig. 2 insbesondere zu erkennen.The ambient light scattering during the optical detection of the flashing pattern 4a of the lamp 2a, which can also include a flashing pattern 4b of another lamp 2b, natural sunlight, flickering and / or flickering and / or flickering of other lamps, not shown, etc., can be made by the device 3 does not impair its function, because according to the invention it has a photodiode 10a in the form of a component, namely a PIN photodiode ("positive intrinsic negative diode"), as photodetector 10 - as in FIG Fig. 2 in particular to recognize.

Die Sensorfläche weist von 4 bis 9 mm2 (Quadratmillimeter), nämlich von 2,73 x 2,73 mm (Millimeter), auf, was für eine ausreichende Sensitivität bei der Erfassung des Blinkmusters 4a der Leuchte 2a sorgt.The sensor area is 4 to 9 mm 2 (square millimeters), namely 2.73 x 2.73 mm (millimeters), which ensures sufficient sensitivity when detecting the blinking pattern 4a of the lamp 2a.

Zudem ist das Objektiv 11 als Teleobjektiv mit einer Sammellinse 11b ausgebildet, wobei die optoelektronische Einrichtung 9 einen Bildwinkel α im speziellen Bereich von 4 bis 7 Grad, nämlich exakt 5,7 Grad, aufweist, wie in Fig. 2 zu erkennen. Damit kann auch ein Blinkmuster 4b einer vergleichsweise hoch bzw. weit entfernten Leuchten 2b vom Gerät 3 ohne weiteres optisch erfasst werden.In addition, the lens 11 is designed as a telephoto lens with a converging lens 11b, the optoelectronic device 9 having an image angle α in the special range of 4 to 7 degrees, namely exactly 5.7 degrees, as in FIG Fig. 2 to recognize. In this way, a blink pattern 4b of a lamp 2b that is comparatively high or far away can easily be optically detected by the device 3.

Die optoelektronische Einrichtung 9 weist zudem eine dem Objektiv 11 vorgeschaltete Streulichtblende 12 auf, um den Anteil an unerwünschten Umgebungslicht weiter zu reduzieren.The optoelectronic device 9 also has a lens hood 12 connected upstream of the lens 11 in order to further reduce the proportion of undesired ambient light.

Um die jeweilige Leuchte 2a, 2b handhabungsfreundlich vom Gerät 3 anvisieren zu können, ist das Gerät 3 mit einer Laserstrahlquelle 13 versehen, derer Laserstrahl 13a zur optischen Achse 11b des Objektivs 11 hin geneigt verläuft - wie in Fig. 1 und Fig. 2 zu erkennen.In order to be able to aim at the respective lamp 2a, 2b in a manageable manner from the device 3, the device 3 is provided with a laser beam source 13, the laser beam 13a of which is inclined towards the optical axis 11b of the objective 11 - as in FIG Fig. 1 and Fig. 2 to recognize.

Konstruktiv weist das Gerät 3 ein Rohr 14 auf, das den Photodetektor 10 und das Objektiv 11 aufnimmt und zudem auch die Streulichtblende 12 ausbildet, in dem das Rohr 14 dem Objektiv 11 weiter vorragt. Die Innenseite 14a des Rohrs 14 ist schwarz gefärbt, was von der optoelektronischen Einrichtung 9 eingefangenes, unerwünschtes Umgebungslicht weiter reduziert.In terms of construction, the device 3 has a tube 14 which receives the photodetector 10 and the objective 11 and also forms the lens hood 12, in which the tube 14 protrudes further from the objective 11. The inside 14a of the tube 14 is colored black, which further reduces unwanted ambient light captured by the optoelectronic device 9.

Das Gerät 3 weist auch ein Griffteil 15 auf, an dem das Rohr 14 gegenüber der Längsachse 15a des Griffteils 15 abgewinkelt anschließt. Im Griffteil 15 ist eine Batterie 16 zur elektrischen Versorgung des Geräts 3 und auch eine Recheneinrichtung 17 zumindest zur Auswertung der Sensordaten der Photodiode 10a vorgesehen.The device 3 also has a handle part 15 to which the tube 14 is connected at an angle with respect to the longitudinal axis 15a of the handle part 15. A battery 16 for the electrical supply of the device 3 and also a computing device 17 at least for evaluating the sensor data of the photodiode 10a are provided in the handle part 15.
