Description

Die Erfindung betrifft eine Umlichtleuchte für die Flugfeldbeleuchtung umfassend wenigstens ein Leuchtelement zum Abstrahlen von Licht und wenigstens ein dem Leuchtelement zugeordnetes Optikelement zum Umlenken des Lichts in eine Lichtaustrittshauptebene.The invention relates to an ambient light for airfield lighting comprising at least one luminous element for emitting light and at least one optical element associated with the luminous element for deflecting the light into a light exit main plane.

Aus der WO 2001/14789 A1 ist eine Umlichtleuchte für die Flugfeldbeleuchtung bekannt mit einer Mehrzahl von Leuchtelementen, welche mantelseitig an einem im Querschnitt achteckigen Grundkörper befestigt sind. Die Leuchtmittel gewährleisten aufgrund ihrer verteilten Anordnung, dass eine sich in die Querrichtung erstreckende Lichtaustrittshauptebene homogen ausgestrahlt wird. Jedoch ist der Aufbau relativ komplex und bedarf einer Vielzahl von Leuchtmitteln.From the WO 2001/14789 A1 is an ambient light for airfield lighting known with a plurality of lighting elements, which are fixed on the shell side of a cross-sectionally octagonal basic body. Due to their distributed arrangement, the illuminants ensure that a main light exit main plane extending in the transverse direction is emitted homogeneously. However, the structure is relatively complex and requires a variety of bulbs.

Eine weitere Leuchte ist aus der US 2006/0050507 A1 bekannt. Hier wird zur homogenen Ausleuchtung einer Lichtaustrittshauptebene eine seitlich abstrahlende Leuchtdiode als Leuchtelement verwendet. Zur Formung der Lichtverteilung ist eine transparente Abdeckung der Leuchte mit einer Optik vorgesehen.Another light is from the US 2006/0050507 A1 known. Here, a laterally emitting LED is used as a luminous element for the homogeneous illumination of a light exit main plane. To form the light distribution, a transparent cover of the luminaire is provided with an optic.

Aus der US 2003/0193807 A1 ist eine gattungsgemäße Umlichtleuchte mit einer einzigen Leuchtdiode als Leuchtmittel bekannt. Von der Leuchtdiode abgestrahltes Licht trifft auf ein Optikelement und wird dort in Richtung einer Lichtaustrittshauptebene der Leuchte umgelenkt. Das Optikelement ist hierbei als Reflektorelement ausgebildet. Eine optische Achse der Leuchtdiode, welche eine Hauptabstrahlrichtung des von der Leuchtdiode abgestrahlten Lichts definiert, ist um 90° winkelversetzt zur Lichtaustrittshauptebene orientiert. Die US2012/0182730 A1 und FR 2936297 offenbaren weitere Umlichtleuchten des Stands der Technik.From the US 2003/0193807 A1 a generic ambient light with a single light emitting diode is known as a light source. Light emitted by the light-emitting diode strikes an optical element and is deflected there in the direction of a light exit main plane of the light. The optical element is designed here as a reflector element. An optical axis of the light-emitting diode, which defines a main emission direction of the light emitted by the light-emitting diode, is oriented at 90 ° at an angle to the light exit main plane. The US2012 / 0182730 A1 and FR 2936297 disclose further ambient light lamps of the prior art.

Aufgabe der Erfindung ist es, eine optisch hochwirksame Umfeldleuchte für die Flugfeldbeleuchtung anzugeben, welche eine homogene Ausleuchtung in Bezug auf eine Lichtaustrittshauptebene gewährleistet und dabei kostengünstig und einfach im Aufbau ist.The object of the invention is to provide an optically highly effective ambient light for airfield lighting, which ensures a homogeneous illumination with respect to a main light exit plane and is inexpensive and simple in construction.

Zur Lösung der Aufgabe ist die Erfindung in Verbindung mit dem Oberbegriff des Patentanspruchs 1 dadurch gekennzeichnet, dass auf einer dem Leuchtelement zugewandten Rückseite weist das Optikelement die Ausnehmung auf, wobei eine Mantelfläche der Ausnehmung ist als Lichteintrittsfläche des Optikelements ausgebildet ist, die Lichteintrittsfläche wird aus einer Mehrzahl von Teilflächen gebildet, von denen je ein zylindersegmentmantelförmig, kugelsegmentmantelförmig, kegelstumpfsegmentmantelförmig beziehungsweise eben ist, die Lichtaustrittsfläche wird von zwei konvex gekrümmte Teilflächen gebildet, wobei die konvex gekrümmte Teilflächen eine gemeinsame Verbindungskante aufweisen und die Verbindungskante sich in die Lichtaustrittshauptebene der Umlichtleuchte erstreckt und so dass die Lichteintrittsfläche des Optikelements und/oder die Lichtaustrittsfläche des Optikelements derart geformt und/oder positioniert sind und/oder dass das Leuchtelement dem Optikelement derart zugeordnet ist, dass von dem Leuchtelement abgestrahltes Licht und von dem Optikelement von der optischen Achse nach außen umgelenktes Licht in der Lichtaustrittshauptebene einen horizontalen Winkelbereich von -95° bis +95° in Bezug auf die Hauptabstrahlrichtung des Lichts homogen ausleuchtet.To solve the problem, the invention in conjunction with the preamble of claim 1, characterized in that on a light element facing the back, the optical element on the recess, wherein a lateral surface of the recess is formed as a light entrance surface of the optical element, the light entry surface is made of a The light exit surface is formed by two convexly curved partial surfaces, wherein the convexly curved partial surfaces have a common connecting edge and the connecting edge extends into the main light exit main plane of the ambient light and so that the light entry surface of the optical element and / or the light exit surface of the optical element are shaped and / or positioned in such a way and / or that the light element to the optical element so is ordered that radiated light from the luminous element and from the optical element from the optical axis to the outside deflected light in the light exit main plane a horizontal angle range of -95 ° to + 95 ° with respect to the main emission of the light homogeneously illuminated.

Der besondere Vorteil der Erfindung besteht darin, dass auf eine 90° Umlenkung des von dem Leuchtelement abgestrahlten Lichts durch das Optikelement verzichtet wird. Insofern ergibt sich eine besonders homogene Lichtverteilung in der Lichtaustrittshauptebene. Darüber hinaus kann ein guter optischer Wirkungsgrad realisiert und die Lichtverteilung durch die Verwendung des lichtbrechenden Optikelements fein justiert beziehungsweise eingestellt werden.The particular advantage of the invention is that it dispenses with a 90 ° deflection of the light emitted by the luminous element through the optical element. In this respect, a particularly homogeneous light distribution results in the light exit main plane. In addition, a good optical efficiency can be realized and the light distribution can be finely adjusted or adjusted by the use of the refractive optical element.

Nach einer bevorzugten Ausführungsform der Erfindung sind die Lichteintrittsflächen des Optikelements beziehungsweise die Lichtaustrittsflächen des Optikelements derart geformt beziehungsweise positioniert und das Leuchtelement dem Optikelement derart zugeordnet, dass von dem Leuchtelement abgestrahltes Licht und von dem Optikelement umgelenktes Licht in der Lichtaustrittshauptebene einen horizonalen Winkelbereich von -95° bis +95° in Bezug auf die Hauptabstrahlrichtung des Lichts homogen ausgeleuchtet wird und dass von dem Leuchtelement abgestrahltes Licht und von dem Optikelement umgelenktes Licht einen vertikalen Winkelbereich von -1° bis +16° zur Lichtaustrittshauptebene homogen ausleuchtet. Vorteilhaft ergibt sich in der Lichtaustrittshauptebene ein großer horizontaler Winkelbereich, welcher mehr als eine Halbebene umfasst und insofern eine vollständige Ausleuchtung der Lichtaustrittshauptebene mit einer sehr begrenzten Anzahl von Leuchtelementen ermöglicht. Auch quer zur Lichtaustrittshauptebene ist der funktional vorgegebene vertikale Winkelbereich von -1° bis +16° homogen ausgeleuchtet. Es ergibt sich insofern eine konstruktiv einfache, kostengünstige Leuchtenanordnung. Im Extremfall müssen lediglich zwei Leuchtelemente mit zugeordneten Optikelementen vorgesehen werden, um die Lichtaustrittshauptebene vollständig und entsprechend der gesetzlichen Vorgaben auszuleuchten.According to a preferred embodiment of the invention, the light entry surfaces of the optical element or the light exit surfaces of the optical element are shaped or positioned and the light element associated with the optical element such that light emitted by the light element and deflected by the optical element light in the light exit main plane a horizontal angle range of -95 ° to + 95 ° is homogeneously illuminated in relation to the main emission direction of the light and that light emitted by the luminous element and light deflected by the optical element homogeneously illuminates a vertical angle range of -1 ° to + 16 ° relative to the light exit main plane. Advantageously results in the light exit main plane is a large horizontal angle range, which comprises more than a half-plane and thus allows complete illumination of the light exit main plane with a very limited number of light elements. Also transversely to the light exit main plane of the functionally predetermined vertical angle range of -1 ° to + 16 ° is homogeneously illuminated. This results in a structurally simple, inexpensive lighting arrangement. In extreme cases, only two light elements with associated optical elements must be provided in order to illuminate the light exit main plane completely and in accordance with the legal requirements.

Grundgedanke der Erfindung ist es hierbei, das Optikelement mit der Lichteintrittsfläche und der Lichtaustrittsfläche derart zu formen und relativ zu dem Optikelement anzuordnen, dass Licht nach vorne, seitlich und teilweise auch nachhinten die durch die Leuchtelemente definierte Ebene umgelenkt beziehungsweise ausgekoppelt wird. Bei Verwendung einer Mehrzahl von Leuchtdioden werden insofern nicht ausgestrahlte Bereiche nahezu vollständig vermieden.The basic idea of the invention here is to form the optical element with the light entry surface and the light exit surface in such a way and to arrange it relative to the optical element such that light is deflected or coupled out to the front, laterally and partly also to the rear through the plane defined by the light elements. When using a plurality of light emitting diodes so far radiated areas are almost completely avoided.

Erfindungsgemäß weist das Optikelement auf einer dem Leuchtelement zugewandten Rückseite eine zur Aufnahme des Leuchtelements ausgebildete Ausnehmung auf. Eine Mantelfläche der Ausnehmung definiert hierbei die Lichteintrittsfläche des Optikelements. Vorteilhaft ergibt sich eine hohe optische Güte, wenn die Lichteintrittsfläche durch die Ausnehmung definiert ist und das Leuchtelement der Ausnehmung zugeordnet wird. Beispielsweise kann die Lichteintrittsfläche des Optikelements wenigstens abschnittsweise eben beziehungsweise konkav gekrümmt ausgebildet sein. Insbesondere kann vorgesehen sein, dass die Lichteintrittsfläche aus einer Mehrzahl von Teilflächen gebildet wird, welche aneinander anliegen und entsprechend der optischen Erfordernisse geformt sind. Eine erste Teilfläche kann beispielsweise nach Art einer Zylindermantelteilfläche im Querschnitt kreissegmentförmig gekrümmt sein. Eine zweite Teilfläche kann nach Art einer Kugelmantelfläche gänzlich gekrümmt sein. Eine dritte Teilmantelfläche kann etwa nach Art einer Kegelstumpfmantelfläche ausgebildet sein. Eine weitere Teilfläche der Lichteintrittsfläche kann beispielsweise nach Art einer Freiformfläche geometrisch beliebig gestaltet sein. Ebenso ist es möglich, eine Teilfläche der Lichteintrittsfläche eben auszubilden.According to the invention, the optical element has a recess formed on the rear side facing the luminous element for receiving the luminous element. A lateral surface of the recess defines the light entry surface of the optical element. Advantageously, a high optical quality results if the light entry surface is defined by the recess and the luminous element is assigned to the recess. For example, the light entry surface of the optical element may be designed to be flat or concave curved at least in sections. In particular, it may be provided that the light entry surface is formed from a plurality of partial surfaces, which abut each other and are shaped according to the optical requirements. A first partial surface may, for example, be curved in a circular segment shape in cross section in the manner of a cylinder jacket partial surface. A second partial surface can be completely curved in the manner of a spherical lateral surface. A third partial circumferential surface may be formed approximately in the manner of a truncated cone lateral surface. A further partial surface of the light entry surface can be designed to be geometrically arbitrary, for example, in the manner of a free-form surface. It is also possible to form a partial surface of the light entry surface flat.

Nach der Erfindung weist die Lichtaustrittsfläche wenigstens zwei optisch wirksame konvex gekrümmte Teilflächen auf. Erfindungsgemäß ist zwischen den zwei Teilflächen der Lichtaustrittsflächen eine gemeinsame Verbindungskante ausgebildet, welche sich in die Lichtaustrittshauptebene erstreckt. Vorteilhaft kann durch das Vorsehen der zwei Teilflächen eine besonders hohe Homogenität sowohl in der Lichtaustrittshauptebene als auch senkrecht dazu im Winkelbereich von -1° bis +16° erreicht werden.According to the invention, the light exit surface has at least two optically effective convexly curved partial surfaces. According to the invention, a common connecting edge is formed between the two partial surfaces of the light exit surfaces, which extends into the main light exit plane. Advantageously, by providing the two partial surfaces, a particularly high homogeneity can be achieved both in the main light exit plane and perpendicular to it in the angular range of -1 ° to + 16 °.

Um eine gleichmäßige Ausleuchtung der gesamten Lichtaustrittshauptebene zu bewirken, können erfindungsgemäß zwei gleiche Leuchtelemente und zwei den Leuchtelementen zugeordnete Optikelemente vorgesehen sein. Die Leuchtelemente und die Optikelemente sind einander derart zugeordnet, dass das Licht in zwei um 180° entgegengesetzt zueinander orientierte Hauptabstrahlrichtungen abgestrahlt wird.In order to effect a uniform illumination of the entire light exit main plane, two identical light elements and two optical elements associated with the light elements can be provided according to the invention. The light-emitting elements and the optical elements are assigned to one another in such a way that the light is emitted in two main emission directions oriented by 180 ° in opposite directions to one another.

The luminaire has two light elements 1 which are rotated by 180 ° relative to one another and two optical elements 2 assigned to the luminous elements 1. Furthermore, the lamp has two further lighting modules 3 for realizing a further light function.

Die Leuchtelemente 1 sind in dem Ausführungsbeispiel der Erfindung nach Art von Leuchtdioden ausgebildet. Die Optikelemente 2 sind als lichtbeugende Optikelemente 2 realisiert. Sie sind den Leuchtelementen 1 derart zugeordnet, dass von dem Leuchtelement 1 abgestrahltes Licht in das Optikelement 2 eingekoppelt, umgelenkt und in eine Lichtaustrittshauptebene 10 abgestrahlt wird.The light-emitting elements 1 are formed in the embodiment of the invention in the manner of light-emitting diodes. The optical elements 2 are realized as light-diffractive optical elements 2. They are associated with the lighting elements 1 in such a way that light emitted by the lighting element 1 is coupled into the optical element 2, deflected and emitted into a light exit main plane 10.

Den Aufbau des Optikelements 2 zeigt Fig. 2. Das Optikelement 2 besteht aus einem transparenten Optikkörper. Auf einer im montierten Zustand des Optikelements 2 dem Leuchtelement 1 zugewandten Rückseite 4 weist das Optikelement 2 eine Ausnehmung 5 auf. Eine Mantelfläche der Ausnehmung 5 ist als Lichteintrittsfläche 6 des Optikelements 2 ausgebildet. Die Lichteintrittsfläche 6 wird aus einer Mehrzahl von Teilflächen 6.1, 6.2, 6.3, 6.4 gebildet, welche zylindersegmentmantelförmig (Teilfläche 6.1), kugelsegmentmantelförmig (Teilfläche 6.2), kegelstumpfsegmentmantelförmig (Teilfläche 6.3) beziehungsweise eben (Teilfläche 6.4) ausgebildet sind.The structure of the optical element 2 shows Fig. 2 , The optical element 2 consists of a transparent optical body. On a in the assembled state of the optical element 2 the light-emitting element 1 facing back 4, the optical element 2 has a recess 5. A lateral surface of the recess 5 is formed as a light entry surface 6 of the optical element 2. The light entrance surface 6 is formed from a plurality of partial surfaces 6.1, 6.2, 6.3, 6.4, which are cylindrical segment jacket-shaped (partial surface 6.1), spherical segment jacket-shaped (partial surface 6.2), truncated cone-shaped jacket (partial surface 6.3) or flat (partial surface 6.4) are formed.

Als weitere lichttechnisch wirksame Fläche ist eine durch zwei konvex gekrümmte Teilflächen (7.1, 7.2) gebildete Lichtaustrittsfläche 7 vorgesehen. Die zwei optisch wirksamen Teilflächen (7.1, 7.2) der Lichtaustrittsfläche 7 weisen eine gemeinsame Verbindungskante 8 auf. Die Verbindungskante 8 erstreckt sich in die Lichtaustrittshauptebene 9 der Leuchte.As a further photometrically effective surface, a light exit surface 7 formed by two convexly curved partial surfaces (7.1, 7.2) is provided. The two optically effective partial surfaces (7.1, 7.2) of the light exit surface 7 have a common connecting edge 8. The connecting edge 8 extends into the light exit main plane 9 of the lamp.

Die Fig. 3 und 4 zeigen die horizontale beziehungsweise vertikale Lichtverteilung der Leuchte. Bezüglich der horizontalen Lichtverteilung wird deutlich, dass von dem Leuchtelement 1 abgestrahltes Licht in der Lichtaustrittshauptebene 9 beim Eintritt in das Optikelement 2 von der optischen Achse des Leuchtelements 1 beziehungsweise der Hauptabstrahlrichtung 10 weg nach außen gebrochen wird. Eine weitere Brechung nach außen erfolgt beim Austritt aus dem Optikelement 2 derart, dass in Bezug auf die Hauptabstrahlrichtung 10 des Lichts ein horizontaler Winkelbereich 11 von -95° bis +95° in der Lichtaustrittshauptebene 9 homogen ausgestrahlt wird.The Fig. 3 and 4 show the horizontal and vertical light distribution of the lamp. With regard to the horizontal light distribution, it is clear that light emitted by the luminous element 1 in the light exit main plane 9 is refracted outwards on entry into the optical element 2 away from the optical axis of the luminous element 1 or the main emission direction 10. A further refraction to the outside occurs at the exit from the optical element 2 such that with respect to the main emission direction 10 of the light, a horizontal angle range 11 of -95 ° to + 95 ° in the light exit main plane 9 is homogeneously emitted.

Bezüglich der vertikalen Lichtverteilung zeigt Fig. 4, dass das aus dem Optikelement 2 ausgekoppelte Licht im Wesentlichen in einem vertikalen Winkelbereich 12 von -1° bis +16° in Bezug auf die Hauptabstrahlrichtung 10 verteilt wird. Dieser Bereich ist entsprechend der gesetzlichen Vorgaben homogen ausgeleuchtet. Zusätzliches Licht wird insbesondere nach oben, das heißt nominell um 90° versetzt zur Lichtaustrittshauptebene 9 beziehungsweise zur Hauptabstrahlrichtung 10 des Lichts umgelenkt.Regarding the vertical light distribution shows Fig. 4 in that the light coupled out of the optical element 2 is distributed substantially in a vertical angle range 12 of -1 ° to + 16 ° with respect to the main emission direction 10.
