Abstract

For known lighting fixtures, the illuminated area is defined insufficiently. The novel lighting fixture should illuminate a defined area, for example, a rectangular area. For this purpose, 3-dimensional convex reflectors (3), which are irradiated by light emitting diodes (2), are used. The radiating characteristic of this light reflector unit is determined by changing the position of the light with respect to the reflector unit. Because of the low energy required, the lighting fixture is suitable, for example, as a streetlight which, in case of need, is supplied with power by means of a battery (11) and which is regenerated during the day by means of a photovoltaic module (12).

Description

Leuchte lamp
Die Erfindung bezieht sich auf eine Leuchte mit Leuchtmitteln und mit Reflektoren.The invention relates to a luminaire with bulbs and reflectors.
Derartige Leuchten sind vielfach bekannt. Ausgehend vom Stand der Technik liegt der Erfindung die Aufgabe zugrunde, eine Leuchte mit den im Oberbegriff des Anspruchs 1 angegebenen Merkmalen derart weiterzubilden, dass ihre Nutzungsmöglichkeiten erweitert sind, die Effizienz gesteigert und sich insbesondere eine definierte Ausleuchtung der zu bestrahlenden Fläche ergibt.Such lights are widely known. Starting from the prior art, the invention has the object, a luminaire with the features specified in the preamble of claim 1 in such a way that their uses are expanded, increased efficiency and in particular results in a defined illumination of the surface to be irradiated.
Diese Aufgabe wird gemäß der Erfindung dadurch gelöst, dass ein Leuchtmittel (2) auf einen dreidimensional konvex gewölbten Reflektor (3) leuchtet und durch Änderung des Abstandes (7) sowie der horizontalen (9) und vertikalen (8) Parallaxe dessen Abstrahlgeometrie stufenlos und definiert verändert wird.This object is achieved according to the invention in that a lighting means (2) on a three-dimensional convex curved reflector (3) lights and by changing the distance (7) and the horizontal (9) and vertical (8) parallax whose Abstrahlgeometrie stepless and defined is changed.
Weitere vorteilhafte Ausgestaltungen der Erfindung ergeben sich aus den Unteransprüchen.Further advantageous embodiments of the invention will become apparent from the dependent claims.
Die Vorteile der Erfindung bestehen darin, dass eine definierte Fläche durch hoch- effiziente Leuchtmittel - vorzugsweise Leuchtdioden - mit geringem Energieverbrauch blendfrei beleuchtet werden kann. Insbesondere kann durch die besondere Formgebung des Reflektors (3) eine annähernd rechteckige Ausleuchtung (6) erreicht werden [Fig.1]. Durch Veränderung des Abstandes (7) LED / Reflektor wird die Größe der ausgeleuchteten Fläche (6, 6a) variiert, ohne die Geometrie der beleuchteten Fläche wesentlich zu beeinflussen [Fig.2]. Durch Verschiebung der Parallaxe LED / Reflektor in der Vertikalen (8) wird eine stufenlose Änderung des Abstrahlwinkels in der X-Achse eingestellt. Die Y-Achse wird hierbei nicht wesentlich beeinflusst [Fig.4]. Durch Verschiebung der Parallaxe LED / Reflektor in der Horizontalen (9) wird der Abstrahlwinkel der Leuchte in der Y-Achse eingestellt [Fig.3]. Durch die Umlenkung des Lichtstrahles per konvexen Spiegel (3) und einer Blende (4) unterhalb des Leuchtmittels wird die Blendfreiheit erzielt. Durch Kombination mehrerer Leuchtmittel und Reflektoreinheiten kann die Abstrahlcharakteristik weitergehend beeinflusst und die Leuchtstärke der Gesamteinheit den Erfordernissen angepasst werden [Fig.5, Fig.6]. Der geringe Energieverbrauch prädestiniert die Leuchte für den Einsatz im nicht netzgebundenem Betrieb per Batterie oder Akkumulator. Akkumulatoren können wiederum per Solar- oder Windenergie regeneriert werden und somit in Kombination mit der Leuchte eine autark arbeitende Einheit bilden [Fig.7]. Als Ersatz für bestehende, netzbetriebene Leuchten liegt der Vorteil im geringeren Stromverbrauch bei ähnlicher Lichtleistung auf die auszuleuchtende Fläche.The advantages of the invention are that a defined surface can be illuminated glare-free by means of highly efficient light sources, preferably light-emitting diodes, with low energy consumption. In particular, by the special shape of the reflector (3) an approximately rectangular illumination (6) can be achieved [Fig.1]. By changing the distance (7) LED / reflector, the size of the illuminated surface (6, 6a) is varied, without significantly affecting the geometry of the illuminated surface [Fig.2]. By shifting the parallax LED / reflector in the vertical (8) a stepless change of the beam angle in the X-axis is adjusted. The Y-axis is not significantly affected in this case [Fig.4]. By shifting the parallax LED / reflector in the horizontal (9), the beam angle of the luminaire in the Y-axis is set [Fig.3]. By the deflection of the light beam by convex mirror (3) and a diaphragm (4) below the bulb, the glare is achieved. By combining several lamps and reflector units, the radiation characteristics can be further influenced and the luminosity of the entire unit can be adapted to the requirements [Fig.5, Fig.6]. The low energy consumption predestines the luminaire for use in non-mains-powered operation via battery or accumulator. Rechargeable batteries can in turn be regenerated by solar or wind energy and thus form a self-sufficient unit in combination with the luminaire [Fig. 7]. As a replacement for existing, mains-powered luminaires, the advantage in lower power consumption with similar light output lies on the surface to be illuminated.

Die Fig. 6 zeigt eine Reihenanordnung der Leuchtdioden (2) und eine Reihenanordnung der zugehörigen konvexen Reflektoren (3) in der Draufsicht. Jede der einzelnen LED-Reflektoreinheiten beleuchtet annähernd die gleiche Fläche (6). Werden Leuchtdioden mit unterschiedlichen Leuchtfarben eingesetzt, so ergibt sich auf der bestrahlten Fläche eine gleichförmige Farbmischung; damit ist es möglich, eine Fläche z.B. mit der Lichtfarbe warm-weiß auszuleuchten, indem weiße und gelbe Leuchtdioden kombiniert werden.Fig. 7 exemplary representation of the components of a solar-powered and micro-controller controlled street lamp. Fig. 6 shows a series arrangement of the light emitting diodes (2) and a series arrangement of the associated convex reflectors (3) in plan view. Each of the individual LED reflector units illuminates approximately the same area (6). If light-emitting diodes with different luminous colors are used, a uniform color mixture results on the irradiated surface; This makes it possible to illuminate a surface, for example with the light color warm white, by combining white and yellow light-emitting diodes.
In Fig. 7 ist beispielhaft eine solarbetriebene Straßenlaterne als Blockschaltbild dargestellt. Sie besteht aus der Leuchte (1 ) einem Photovoltaik-Modul (12), einem Akku (11 ) und einer zentralen Mikrokontrollersteuerung (10). Am Tage wird der Akku (11 ) bei ausreichender Sonneneinstrahlung mittels dem Photovoltaik-Modul (12) und der Mikrokontrollersteuerung (10) mit elektrischer Energie aufgeladen. Nachts versorgt der Akku (11 ), geregelt per Mikrokontrollersteuerung (10), die Leuchte (1 ) mit Strom. Der Mikrocontroller (10) gewährleistet eine hohe Energieeffizienz, sowohl in Bezug auf optimierte Lade- und Entladevorgänge des Akkus (11), wie auch in Bezug auf die abgegebene Lichtleistung. Bei Akkumulatorladung wird zur Schonung des Akkus (11 ) und zur Erreichung einer möglichst ununterbrochenen Ersetzbarkeit die in den Akku (11 ) eingespeiste, wie auch die entnommene Energiemenge der zurückliegenden Lade- bzw. Entladezyklen gemessen und bewertet. Bei zu geringer Energieeinspeisung wird die abgegebene Lichtleistung beim nächsten Entladevorgang entsprechend reduziert. Durch diese Maßnahmen wird in Verbindung mit langlebigen und robusten Leuchtdioden (2) als Leuchtmittel eine lange Lebensdauer aller eingesetzten Komponenten einhergehend mit entsprechend langen Wartungsintervallen erzielt.FIG. 7 shows, by way of example, a solar-powered street lamp as a block diagram. It consists of the lamp (1) a photovoltaic module (12), a battery (11) and a central microcontroller controller (10). During the day, the battery (11) is charged with sufficient solar radiation by means of the photovoltaic module (12) and the microcontroller controller (10) with electrical energy. At night, the battery (11), regulated by microcontroller control (10), the lamp (1) supplied with power. The microcontroller (10) ensures high energy efficiency, both in terms of optimized charging and discharging the battery (11), as well as in terms of the output light output. When battery charge is to protect the battery (11) and to achieve the most continuous replaceability in the battery (11) fed, as measured and evaluated the amount of energy removed the past charge or discharge cycles. If the energy supply is too low, the emitted light output will be reduced accordingly during the next discharge process. These measures, in conjunction with long-lasting and robust light-emitting diodes (2) as a light source, achieve a long service life of all components used along with correspondingly long maintenance intervals.
In Gegenden mit generell geringer Sonneneinstrahlung kann alternativ oder zusätzlich zum Photovoltaik-Modul (12) ein Kleinwindgenerator zum Einsatz kommen.In areas with generally low solar radiation, alternatively or in addition to the photovoltaic module (12), a small wind generator can be used.
Per Sensoren und Aktoren (13) können Zusatzfunktionen ausgeführt werden. Beispielhaft sind Notruffunktionen, Messdatenerfassung, situationsabhängige Helligkeitsregelung und externe, zentrale Leuchtensteuerungen möglich. Eine Einheit nach diesen Vorgaben arbeitet vollkommen autark und ist nicht von einer energieversorgenden Topologie abhängig. BezugszeichenlisteBy means of sensors and actuators (13) additional functions can be performed. For example, emergency call functions, data acquisition, situation-dependent brightness control and external, central lighting control are possible. A unit according to these specifications works completely self-sufficient and does not depend on an energy-supplying topology. LIST OF REFERENCE NUMBERS
