Abstract
Description
Die Erfindung betrifft eine Außenleuchte zur Beleuchtung von Geländen, insbesondere von Straßen, Plätzen usw.The invention relates to an outdoor lamp for lighting terrain, in particular streets, squares, etc.
Die Beleuchtung von Straßen, Plätzen usw. erfolgt im Allgemeinen mit Leuchten, die in einer Höhe (Lichtpunkthöhe) zwischen 4 Meter und 20 Metern über der zu beleuchtenden Fläche an Masten, Abspannseilen oder Häuserfassaden angebracht sind.The lighting of streets, squares, etc. is generally carried out with luminaires mounted on poles, guy ropes or house facades at a height (point height) between 4 meters and 20 meters above the surface to be illuminated.
Die unterschiedlichen Lichtpunkthöhen ergeben sich aus den unterschiedlichen Anwendungsfällen, z. B. der Größe der zu beleuchtenden Fläche oder des Abstandes der Leuchten zueinander. Wesentliches Ziel ist es, dass diese Leuchten möglichst einen großen Bereich gleichmäßig ausleuchten. Das wird u. a. dadurch erreicht, dass die Höhe der Lichtpunkte nach oben hin optimiert wird.The different light heights result from the different applications, eg. As the size of the surface to be illuminated or the distance of the lights to each other. The essential goal is that these lights illuminate a large area as evenly as possible. This will u. a. achieved in that the height of the light points is optimized upwards.
Üblicherweise kommen Natriumdampf-Hochdrucklampen und Quecksilberdampflampen im Bereich der erforderlichen Leistung von 50 W bis 1000 W zum Einsatz. Diese Leuchtmittel verlangen auf Grund ihrer Strahlenmodell-Charakteristik einen dreidimensional ausgeformten Reflektor, der für die Lichtstärkeverteilung optimiert wird.Usually, high-pressure sodium vapor lamps and mercury-vapor lamps are used in the range of the required power of 50 W to 1000 W. Due to their radiation pattern characteristics, these lamps require a three-dimensionally shaped reflector which is optimized for the distribution of light intensity.
Ein Beispiel für derartige Leuchten ist in dem deutschen Gebrauchsmuster
Natriumdampf-Hochdruck- und Quecksilberdampflampen haben jedoch eine relativ begrenzte Lebensdauer, so dass sie des Öfteren ersetzt werden müssen, wodurch hohe Kosten entstehen. Auch ist der Energiebedarf der in diesen bekannten Leuchten verwendeten Lampen relativ hoch.However, high-pressure sodium and mercury vapor lamps have a relatively limited life, so they must be replaced frequently, which high costs arise. Also, the energy consumption of the lamps used in these known lights is relatively high.
Um die Lebensdauer zu verlängern und den Energiebedarf zu senken, wurde eine mit Hochleistungs-Leuchtdioden (LED's) bestückte Außenleuchte entwickelt, die im deutschen Gebrauchsmuster
Eine Weiterentwicklung vorgenannter Außenleuchte auf LED-Basis wird in dem deutschen Gebrauchsmuster
Außerdem bleibt das beschriebene Prinzip der Leuchten an Masten oder Abspannseilen oder an Häuserfassaden mit einer auffällig hohen Lichtpunkthöhe auch bei einer Substitution der genannten Leuchtmittel durch LED's bestehen.In addition, the principle described remains the lights on poles or guy ropes or house facades with a conspicuous high light height even with a substitution of the aforementioned bulbs by LEDs.
Das vorstehend beschriebene, bisher zur Anwendung gekommene Beleuchtungsprinzip hat folgende Nachteile:The above-described, previously used lighting principle has the following disadvantages:
Die Energieeffizienz ist durch die genannten großen Lichtpunkthöhen mangelhaft. Die Beleuchtungsstärke nimmt im Quadrat der Entfernung von der zu beleuchtenden Fläche immer weiter ab. Der bisherige Trend, immer höhere Lichtpunkthöhen zu wählen, steht der Forderung nach einer höheren Energieeffizienz konträr entgegen. Durch die großen Lichtpunkthöhen entsteht ein erheblicher uneffizienter Anteil an der gesamten Strahlleistung einer Leuchte, der nicht für die eigentliche Sehaufgabe genutzt wird. Es werden z. B. ungewollt Hausfassaden oder rückwärtige Grundstücke oder andere Flächen mit beleuchtet. Nach eingehenden messtechnischen Untersuchungen gibt es Anwendungsfälle, bei denen nur 5 % der eigentlichen Strahlleistung für die eigentliche Sehaufgabe verwendet wird, d. h., es entsteht ein erheblicher Anteil an ungewollter Lichtimmission.Energy efficiency is inadequate due to the above-mentioned high light heights. The illuminance decreases in the square of the distance from the surface to be illuminated more and more. The previous trend of choosing ever higher light heights is contrary to the demand for higher energy efficiency. Due to the large light heights, a significant inefficient portion of the total beam power of a luminaire, which is not for the actual visual task is being used. There are z. B. unintentionally illuminated house facades or backward plots or other surfaces. After detailed metrological investigations, there are applications in which only 5% of the actual beam power is used for the actual visual task, ie, there is a significant proportion of unwanted light immission.
Der Erfindung liegt deshalb die Aufgabe zugrunde, eine für die Beleuchtung eines Geländes, insbesondere von Straßen und Plätzen geeignete Außenleuchte zu schaffen, bei der die Lichtquelle näher an das zu beleuchtende Gelände herangeführt ist und das zu beleuchtende Gelände dennoch gleichmäßig ausgeleuchtet wird.The invention is therefore an object of the invention to provide a suitable for the lighting of a terrain, especially streets and squares outdoor lamp in which the light source is brought closer to the terrain to be lit and the area to be illuminated is still illuminated uniformly.
Die Aufgabe wird durch das kennzeichnende Merkmal des Schutzanspruches 1 gelöst. Vorteilhafte Ausführungsformen der Erfindung bilden die Kennzeichen der Unteransprüche 2 bis 5.The problem is solved by the characterizing feature of the protection claim 1.

In
Die lichtlenkende Einheit 6 besitzt eine zirkulare und/oder lineare Fresnelllinsen- und/oder Mikroprismenstruktur, und durch deren gezielte optische Gestaltung wird das Licht ausschließlich auf die zu beleuchtenden Flächen geleitet und eine Abstrahlung in Richtungen, die kein Licht benötigen, z. B. nach oben verhindert. Die nahe Heranführung der Leuchte 1 an die zu beleuchtenden Flächen sowie die gezielte Abstrahlung des Lichtes ausschließlich in Richtungen, in denen das Licht auch tatsächlich erforderlich ist, erhöhen die Energieeffizienz der erfindungsgemäßen Leuchten im Vergleich zu Leuchten des Standes der Technik beträchtlich. Obwohl auch bei den Leuchten des Standes der Technik bereits energiesparende Hochleistungs-LED's zum Einsatz kamen, wurden durch die zur Ausleuchtung der Flächen für notwendig gehaltenen großen Lichtpunkthöhen die durch die LED's erzielten Energieeinsparungen zum großen Teil wieder zunichte gemacht, weil die Beleuchtungsstärke sich im Quadrat der Entfernung der Lichtquelle von der zu beleuchtenden Fläche verringert.The light-directing
Mit den erfindungsgemäßen Leuchten spielt die bei den Leuchten des Standes der Technik als Minimum angegebene Lichtpunkthöhe von 4 Metern keine Rolle mehr, d. h. die Lichtpunkthöhen der erfindungsgemäßen Leuchten liegen in der Regel weit unter 4 Metern.With the luminaires according to the invention, the minimum height of 4 meters indicated in the luminaires of the state of the art plays no role, d. H. the light spot heights of the lights according to the invention are usually far below 4 meters.

Die lichtlenkende Einheit 6 ist bei dieser Ausführungsform eine ebene Platte mit einer zirkularen und/oder linearen Fresnelllinsen- und/oder Mikroprismenstruktur. Die Fresnelllinsen- und/oder Mikroprismenstruktur ist dem konkreten Anwendungsfall der Leuchte in der Weise angepasst, dass die Lichtstrahlen optisch ausschließlich zu den zu beleuchtenden Flächen, z. B. bis zur Grenze der Ausleuchtung durch die benachbarten Leuchten gelenkt werden.The light-directing
Die lichtlenkende Einrichtung 6 ist in dem hier beschriebenen Ausführungsbeispiel eine ebene Platte. Sie kann aber ebenso eine gewölbte Platte sein, wenn dementsprechend die Fresnelllinsen- und/oder Mikroprismenstruktur mit der Wölbung abgestimmt wird.The light-directing
Diese an den Straßenecken angeordneten säulenartigen Leuchten können z. B. auch mit einer Verkehrsampelanlage kombiniert werden.These arranged on the street corners columnar lights can z. B. also be combined with a traffic signal system.
Durch die erfindungsgemäßen Außenleuchten lassen sich im Vergleich zu den bekannten Außenleuchten beträchtliche Energieeinsparungen erzielen.By the outdoor lights according to the invention can be achieved in comparison to the known outdoor lights considerable energy savings.
