Description

Die Erfindung betrifft eine Leuchte zur Erzeugung eines länglichen Lichtbildes mit einem liegenden Leuchtmittel und einem Kastenreflektor, der eine gewölbte Reflektorfläche und seitlich die gewölbte Reflektorfläche einfassende planare Reflektorflächen aufweist, wobei das liegende Leuchtmittel senkrecht zu den seitlichen planaren Reflektorflächen angeordnet ist.The invention relates to a luminaire for generating an elongated light image with a horizontal illuminant and a box reflector having a curved reflector surface and laterally the curved reflector surface enclosing planar reflector surfaces, wherein the luminous means lying is arranged perpendicular to the lateral planar reflector surfaces.

Warenpräsentationsflächen wie beispielsweise Kühltheken, Obstschütten, Verkaufsregale etc. werden in der Regel künstlich beleuchtet. Ziel ist es dabei, diese möglichst gleichmäßig auszuleuchten, was auf Grund der üblichen langgezogenen Rechteckform dieser Verkaufsmöbel nur bedingt möglich ist oder eine Vielzahl von Leuchten erfordert.Goods presentation areas such as refrigerated counters, fruit pots, shelves, etc. are usually artificially illuminated. The aim is to illuminate this as evenly as possible, which is due to the usual elongated rectangular shape of this sales furniture is only possible to a limited extent or requires a variety of lights.

In der DE 298 12 344 U1 ist eine Leuchte zur Erzeugung einer länglichen leuchtenden Fläche beschrieben, welche ein liegendes Leuchtmittel und einen Kastenreflektor aufweist. Der Kastenreflektor hat eine gewölbte Reflektorfläche und diese seitliche einfassende planare Reflektorflächen. Das liegende Leuchtmittel ist senkrecht zu den seitlichen planaren Reflektorflächen angeordnet. Beim Betrieb erzeugt die Leuchte eine längliche leuchtende Fläche, die längs zu dem liegenden Leuchtmittel angeordnet ist und deren Länge im wesentlichen von der des liegenden Leuchtmittels bestimmt wird.In the DE 298 12 344 U1 a luminaire for generating an elongated luminous surface is described, which has a horizontal illuminant and a box reflector. The box reflector has a curved reflector surface and these lateral enclosing planar reflector surfaces. The lying light source is arranged perpendicular to the lateral planar reflector surfaces. In operation, the luminaire generates an elongated luminous surface which is arranged longitudinally to the lying luminous means and whose length is essentially determined by that of the luminous means lying.

Nachteil dieser Leuchte ist, dass, wenn sie in einem großen Abstand von den Warenpräsentationsflächen positioniert ist, der Nutzbeleuchtungs-Wirkungsgrad gering werden kann.Disadvantage of this lamp is that when it is positioned at a great distance from the goods display surfaces, the Nutzbeleuchtungs efficiency can be low.

Es ist daher Aufgabe der vorliegenden Erfindung, eine Leuchte der eingangs genannten Art so auszubilden, dass längliche Warenpräsentationsflächen, die insbesondere weiter als 3,5 m von der Leuchte entfernt sind, örtlich gleichmäßig ausgeleuchtet werden können, wobei ein hoher Nutzbeleuchtungswirkungsgrad erzielt wird.It is therefore an object of the present invention, a lamp of the type mentioned in such a way that elongated goods presentation areas, which are more than 3.5 m away from the lamp in particular, can be locally uniformly illuminated, with a high Nutzbeleuchtungswirkungsgrad is achieved.

Diese Aufgabe wird erfindungsgemäß bei einer Leuchte der eingangs genannten Art dadurch gelöst, dass die gewölbte Reflektorfläche ausgebildet ist, die längliche leuchtende Fläche quer zu dem liegenden Leuchtmittel zu erzeugen, und die seitlichen, planaren Reflektorflächen ausgebildet sind, die Längsseiten der länglichen leuchtenden Fläche scharf zu begrenzen.This object is achieved in a lamp of the type mentioned above in that the curved reflector surface is formed to produce the elongated luminous surface transversely to the lying light source, and the lateral, planar reflector surfaces are formed, the long sides of the elongated luminous surface sharp limit.

Grundgedanke der Erfindung ist es also, dass ein Reflektionsraum von einer gewölbten Reflektorfläche, die beispielsweise ellipsen- oder parabelförmig ausgebildet sein kann, und diese seitlich einfassende planare Reflektorflächen gebildet wird. Die gewölbte Reflektorfläche reflektiert das von dem liegenden Leuchtmittel abgestrahlte Licht derart, dass die längliche leuchtende Fläche quer zu dem liegenden Leuchtmittel erzeugt wird, wobei die seitlichen planaren Reflektorflächen dafür sorgen, dass die längliche leuchtende Fläche an ihren Längsseiten scharf begrenzt ist.The basic idea of the invention is therefore that a reflection space is formed by a curved reflector surface, which can be elliptical or parabolic, for example, and these laterally enclosing planar reflector surfaces. The domed reflector surface reflects the light emitted by the underlying illuminant such that the elongated luminous surface is generated transversely to the illuminant lying, the lateral planar reflector surfaces ensuring that the elongated luminous surface is sharply delimited at its longitudinal sides.

Vorteil der erfindungsgemäßen Leuchte ist, dass mit ihrer Hilfe längliche Warenpräsentationsflächen auch aus einer Höhe von mehr als 3,5 m gleichmäßig ausgeleuchtet werden können, wobei ein hoher Nutzbeleuchtungswirkungsgrad erzielt wird.Advantage of the lamp according to the invention is that with their help elongated goods presentation areas can be evenly illuminated from a height of more than 3.5 m, with a high Nutzbeleuchtungswirkungsgrad is achieved.

Gemäß einer Ausführungsform der Erfindung ist vorgesehen, dass in den seitlichen planaren Reflektorflächen Aussparungen vorhanden sind, die von weiteren planar ausgebldeten Reflektorflächen eingefasst werden. Die Aussparungen können insbesondere rechteckig ausgebildet und quer zu der Erstreckung der gewölbten Reflektorfläche angeordnet sein. In diesem Fall weist der Kastenreflektor eine insgesamt kreuzförmige Lichtaustrittsöffnung an seiner Unterseite auf. Ein Vorteil ist herbei, dass noch ein höherer Reflektionsgrad der von dem Leuchtmittel abgegebenen Strahlung erzielt werden kann, wodurch der Beleuchtungsnutzwirkungsgrad weiter erhöht wird.According to one embodiment of the invention it is provided that in the lateral planar reflector surfaces recesses are present, which are bordered by further planar bleached reflector surfaces. The recesses may be formed in particular rectangular and arranged transversely to the extension of the curved reflector surface. In this case, the box reflector on an overall cross-shaped light exit opening on its underside. An advantage of this is that even a higher degree of reflection emitted by the bulb Radiation can be achieved, whereby the lighting efficiency is further increased.

Es ist ebenfalls möglich, als liegendes Leuchtmittel eine Hochdruck-Gasentladungslampe zu verwenden.It is also possible to use a high-pressure gas discharge lamp as lying light source.

In den Figuren 1 bis 3 ist eine erfindungsgemäße Leuchte gezeigt. Die Leuchte weist ein liegendes Leuchtmittel 1 und einen Kastenreflektor 2 auf. Das liegende Leuchtmittel 1 ist hier als Hochdruck-Gasentladungslampe ausgebildet.In the figures 1 to 3, a lamp according to the invention is shown. The luminaire has a horizontal illuminant 1 and a box reflector 2. The lying light source 1 is designed here as a high-pressure gas discharge lamp.

Der Kastenreflektor 2 umfasst eine gewölbte Reflektorfläche 3, die hier parabelförmig ausgebildet ist und seitlich die gewölbte Reflektorfläche 3 einfassende planare Reflektorflächen 4, 5. In den seitlichen planaren Reflektorflächen 4, 5 ist jeweils eine rechteckige Aussparung 6, 7 ausgebildet, die von weiteren planar ausgebildeten Reflektorflächen 8, 9, 10, 11, 12, 13 eingefasst sind. Die Gesamtheit der Reflektorflächen 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13 bildet einen Reflektionsraum 14, der das liegende Leuchtmittel 1 umgibt, und der eine kreuzförmig ausgebildete Lichtaustrittsöffnung 15 an der Unterseite aufweist.The box reflector 2 comprises a curved reflector surface 3, which is parabolic in shape here and laterally the curved reflector surface 3 enclosing planar reflector surfaces 4, 5. In the lateral planar reflector surfaces 4, 5 each have a rectangular recess 6, 7 is formed, formed of further planar Reflector surfaces 8, 9, 10, 11, 12, 13 are bordered. The entirety of the reflector surfaces 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13 forms a reflection space 14, which surrounds the lying light source 1, and which has a cruciform light exit opening 15 at the bottom.

Der Kastenreflektor 2 kann ganz oder teilweise aus Metall mit einer Licht reflektierenden Oberfläche ausgebildet sein.The box reflector 2 may be wholly or partly made of metal with a light-reflecting surface.

Während des Betriebs der Leuchte wird ein Teil der von dem liegenden Leuchtmittel 1 erzeugten Strahlung direkt durch die Lichtaustrittsöffnung 15 in Richtung der erzeugten länglichen leuchtenden Fläche abgegeben. Dabei werden die Längsseiten der länglichen leuchtenden Fläche durch die Anordnung der Reflektorflächen 4, 5, 8, 9, 10, 11, 12, 13 scharf begrenzt.During operation of the luminaire, part of the radiation generated by the lying luminous means 1 is emitted directly through the light exit opening 15 in the direction of the generated elongated luminous surface. The longitudinal sides of the elongated luminous surface are sharply delimited by the arrangement of the reflector surfaces 4, 5, 8, 9, 10, 11, 12, 13.

Ein weiterer Teil der erzeugten Strahlung wird von den Reflektorflächen 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13 des Reflektionsraums 14 in Richtung der länglichen leuchtenden Fläche reflektiert, wodurch ein hoher Nutzbeleuchtungswirkungsgrad erzielt wird. Dabei begrenzen die Reflektionsflächen 4, 5, 6, 7, 8, 9, 10, 11, 12, 13 den Austritt von Streusterahlung so, dass die erzeugte längliche leuchtende Fläche an ihren Längsseiten scharf begrenzt ist. Insgesamt betrachtet ist die längliche leuchtende Fläche quer zu dem liegenden Leuchtmittel 1 ausgerichtet.Another part of the generated radiation is reflected by the reflector surfaces 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13 of the reflection space 14 in the direction of the elongated luminous surface, whereby a high luminous efficiency is achieved. In this case, the reflection surfaces 4, 5, 6, 7, 8, 9, 10, 11, 12, 13 limit the exit of scattered scattering so that the generated elongated luminous surface is sharply delimited on its longitudinal sides. Overall, the elongated luminous surface is aligned transversely to the lying light source 1.

In Figur 4 ist die Lichtverteilung der Leuchte gezeigt. Figur 5 illustriert eine Lichtplanung für drei erfindungsgemäße Leuchten, die mit einem Abstand von 2,5 m zueinander angeordnet sind. Der Abstand zwischen den Leuchten und der zu beleuchtenden länglichen Warenpräsentation beträgt hier 4 m. Deutlich erkennbar ist das längliche scharf begrenze Lichtbild der Leuchte.FIG. 4 shows the light distribution of the luminaire. Figure 5 illustrates a lighting design for three lights according to the invention, which are arranged at a distance of 2.5 m from each other.
