Description

Die vorliegende Erfindung betrifft eine Leuchte mit einer stabförmigen, insbesondere horizontal angeordneten Lichtquelle mit zu beiden Längsseiten der Lichtquelle sich von unterhalb bis oberhalb dieser erstreckenden, konkavgekrümmten Seitenreflektoren, zwischen denen unterhalb der Lichtquelle eine Lichtaustrittsöffnung im Gehäuse ausgebildet ist, wobei unterhalb der Lichtquelle ein Abblendkörper angeordnet ist.The present invention relates to a luminaire with a rod-shaped, in particular horizontally arranged light source with concave-curved side reflectors extending from below to above it on both longitudinal sides of the light source, between which a light outlet opening is formed in the housing below the light source, a dimming body being arranged below the light source is.

Eine derartige Leuchte ist bereits der deutschen Patentanmeldung 36 05 226.4 bekannt. Bei dieser bekannten Leuchte besteht der Abblendkörper aus einem streifenförmigen Flachmaterial, das in seiner Fläche eine Vielzahl von Lichtaustrittsöffnungen aufweist. Durch diesen Abblendkörper soll insbesondere eine Abblendung in Längsrichtung von von der Lichtquelle ausgesandtem Licht gewährleistet werden. Durch die siebartige Ausbildung des Abblendkörpers wird jedoch die Lichtausbeute der Leuchte negativ beeinflußt, auch treten Reflexionen in Längsrichtung nach wie vor auf.Such a lamp is already known from German patent application 36 05 226.4. In this known luminaire, the anti-glare body consists of a strip-shaped flat material which has a large number of light exit openings in its surface. This dimming body is intended in particular to ensure dimming in the longitudinal direction of light emitted by the light source. However, the light output of the luminaire is adversely affected by the screen-like design of the dimming body, and reflections in the longitudinal direction also continue to occur.

Der vorliegenden Erfindung liegt die Aufgabe zugrunde, ausgehend von einer Leuchte der eingangs beschriebenen Art, diese derart zu verbessern, daß sowohl eine optimale Ausblendung der austretenden Lichtstrahlen in Längsrichtung als auch in Querrichtung erreicht wird, und die Lichtausbeute der Leuchte nur geringfügig beeinflußt wird. Gleichzeitig soll eine kostengünstige Herstellung gewährleistet sein.The present invention has for its object, starting from a lamp of the type described above, to improve them in such a way that both an optimal suppression of the emerging light beams in the longitudinal direction and in the transverse direction is achieved, and the luminous efficacy of the luminaire is only slightly influenced. At the same time, cost-effective production should be guaranteed.

Erfindungsgemäß wird dies dadurch erreicht, daß der Abblendkörper aus stark lichtdurchlässigem Stoff besteht und die Lichtquelle zumindest teilweise umfangsgemäß umfaßt, sowie aus einem folienartigen oder dünnwandigen Material besteht, und an seiner der Lichtaustrittsöffnung zugekehrten Oberfläche eine Prismenstruktur aus parallel zur Gehäuselängsachse verlaufenden Prismen aufweist. Vorteilhafterweise ist der Umfassungswinkel des Abblendkörpers derart, daß kein Licht direkt in die Seitenreflektoren von der Lichtquelle eintreten kann.According to the invention, this is achieved in that the anti-glare body consists of highly translucent material and at least partially encompasses the light source circumferentially, and consists of a sheet-like or thin-walled material, and has a prism structure made of prisms running parallel to the longitudinal axis of the housing on its surface facing the light exit opening. Advantageously, the peripheral angle of the anti-glare body is such that no light can enter the side reflectors directly from the light source.

Durch die durch den erfindungsgemäßen Ausblendkörper erzielte Lichtlenkung wird sowohl eine Ausblendung in Querrichtung als auch eine Ausblendung in Längsrichtung der von der Lichtquelle austretenden Lichtstrahlen derart bewirkt, daß keine Blendwirkung durch Spiegelung der Lichtquelle in den Seitenreflektoren oder eventuell vorhandenen Stirnreflektoren erfolgen kann.The light deflection achieved by the masking body according to the invention causes both a masking in the transverse direction and a masking in the longitudinal direction of the light beams emerging from the light source in such a way that there is no glare by reflecting the light source in the side reflectors or any front reflectors that may be present.

Vorteilhafte Ausführungen sind in den Unteransprüchen enthalten. Anhand des in der beiliegenden Zeichnungen dargestellten Ausführungsbeispiels wird die Erfindung näher erläutert. Es zeigen:

Fig. 1
einen Querschnitt durch eine erfindungsgemäße Leuchte,
Fig. 2
eine Ansicht gemäß dem Schnitt II - II in Fig. 1

Advantageous designs are contained in the subclaims. The invention is explained in more detail with reference to the exemplary embodiment illustrated in the accompanying drawings. Show it:
Fig. 1
a cross section through a lamp according to the invention,
Fig. 2
a view according to section II - II in Fig. 1st
Fig. 3
2 shows a longitudinal section through an inventive lamp according to FIG. 1.

Wie sich aus Fig. 1 und 3 ergibt, weist eine erfindungsgemäße Leuchte eine stabförmige, horizontal angeordnete Lichtquelle 1 (Leuchtröhre) auf. Zu beiden Längsseiten der Lichtquelle 1 erstrecken sich von oberhalb bis unterhalb dieser konkav-, insbesondere parabolisch-gekrümmte Seitenreflektoren 2, 3 die zweiteilig oder aber einteilig ausgebildet sein können. In dem Fall, daß die Seitenreflektoren 2, 3 zweiteilig ausgebildet sind, können diese an ihren Oberkanten durch einen Dachreflektor 4 verbunden sein. Es liegt ebenfalls im Rahmen der Erfindung, wenn kein Dachreflektor 4 vorhanden ist, so daß die erfindungsgemäße Leuchte nach oben offen ist. Die Seitenreflektoren 2, 3 können bezüglich der längsverlaufenden, vertikalen Mittelebene 5 symmetrisch ausgebildet sein, es ist jedoch auch eine asymmetrische Ausbildung der Seitenreflektoren zur Mittelebene 5 möglich.1 and 3, a luminaire according to the invention has a rod-shaped, horizontally arranged light source 1 (fluorescent tube). Concave, in particular parabolic, curved side reflectors 2, 3, which can be formed in two parts or in one piece, extend from above to below on both longitudinal sides of the light source 1. In the event that the side reflectors 2, 3 are formed in two parts, they can be connected at their upper edges by a roof reflector 4. It is also within the scope of the invention if there is no roof reflector 4, so that the lamp according to the invention is open at the top. The side reflectors 2, 3 can be formed symmetrically with respect to the longitudinal vertical center plane 5, but an asymmetrical configuration of the side reflectors with respect to the center plane 5 is also possible.

Unterhalb der Lichtquelle 1 ist zwischen den Seitenreflektoren 2, 3 eine Austrittsöffnung 6 vorhanden. Wie Fig. 3 zu entnehmen ist, weist die erfindungsgemäße Leuchte weiterhin zwei Stirnreflektoren 7, 8 auf, die die Seitenreflektoren 2, 3 stirnseitig verbinden. Die Lichtquelle 1 wird in üblicher Weise in Fassungen 9, 9a gehalten.Below the light source 1 there is an outlet opening 6 between the side reflectors 2, 3. As can be seen in FIG. 3, the lamp according to the invention also has two end reflectors 7, 8 which connect the side reflectors 2, 3 on the end face. The light source 1 is held in the usual manner in sockets 9, 9a.

Um eine Ausblendung der von der Lichtquelle 1 austretenden Strahlen, sowohl in Querrichtung als auch in Längsrichtung der Leuchte zu erreichen, ist unterhalb der Lichtquelle 1 ein Abblendkörper 10 angeordnet. Dieser Abblendkörper 10 besteht erfindungsgemäß aus stark durchlässigem Stoff und kann als Folie oder als dünnwandiger, formstabiler Körper ausgebildet sein, wobei der Abblendkörper 10 an seiner der Austrittsöffnung zugekehrten Oberfläche eine Prismenstruktur aus parallel zur Gehäuselängsachse verlaufenden Prismen 11 besitzt, siehe Fig. 2. Diese Prismen 11 sind im dargestellten Ausführungsbeispiel als im Querschnitt gleichschenklige Dreiecke mit einem Spitzenwinkel von 90° ausgeführt. Im dargestellten Ausführungsbeispiel ist der Abblendkörper 10 als sogenannte Zahnfolie insbesondere aus Polyacrylglas hergestellt und ist innerhalb eines Rohres 12 aus einem stark lichtdurchlässigen Stoff, z.B. Polyacrylglas, das die Lichtquelle 1 umschließt, an der Innenseite des Rohres 12 angeordnet. Im dargestellten Ausführungsbeispiel ist der Abblendkörper 10 ebenfalls rohrförmig ausgebildet. Erfindungsgemäß wesentlich ist, daß der Umfassungswinkel des Abblendkörpers 10, mit dem dieser die Lichtquelle umfaßt, und zwar an der der Austrittsöffnung zugekehrten Seite der Lichtquelle, derart bemessen ist, daß kein Licht von der Lichtquelle direkt in die Seitenreflektoren 2, 3 eintreten kann. Im dargestellten Ausführungsbeispiel bedeutet d₁ den Durchmesser des Abblendkörpers 10 im Grund der Prismen 11 und d₂ den mittleren Durchmesser im Bereich der Prismen 11.In order to suppress the rays emerging from the light source 1, both in the transverse direction and in the longitudinal direction of the lamp, a shielding body 10 is arranged below the light source 1. This anti-dazzle device 10 consists according to the invention of highly permeable material and can be designed as a film or as a thin-walled, dimensionally stable body, the shielding body 10 having a prism structure on its surface facing the outlet opening made of prisms 11 running parallel to the longitudinal axis of the housing, see FIG. 2. These prisms 11 are shown in FIG illustrated embodiment executed as isosceles triangles in cross section with a tip angle of 90 °. In the illustrated embodiment, the anti-glare body 10 is made as a so-called toothed foil, in particular made of polyacrylic glass, and is arranged inside a tube 12 made of a highly translucent material, for example polyacrylic glass, which surrounds the light source 1, on the inside of the tube 12. In the illustrated embodiment, the anti-glare body 10 is also tubular. It is essential according to the invention that the circumferential angle of the shielding body 10 with which it surrounds the light source, namely on the side of the light source facing the outlet opening, is dimensioned such that no light can enter the side reflectors 2, 3 directly from the light source. In the illustrated embodiment, d 1 means the diameter of the anti-glare body 10 in the base of the prisms 11 and d 2 the average diameter in the area of the prisms 11.

An Stelle wie in Fig. 1 dargestellt, innerhalb des Rohres 12 eine den Abblendkörper 10 bildenden Folie anzuordnen, kann auch das Rohr selbst unmittelbar an seiner äußeren Oberfläche die erfindungsgemäße Prismenstruktur aufweisen. Auch ist es möglich, um die Lichtquelle 1 herum einen folienartigen Abblendkörper anzuordnen, der durch entsprechende Halterungen in der Leuchte befestigt ist. Im Falle eines geschlossenen, rohrförmigen Abblendkörpers oder einer Anordnung eines beispielsweise folienartigen Abblendkörpers innerhalb eines Rohres, wie in Fig. 1 dargestellt, ist es zweckmäßig, wenn an der der Austrittsöffnung 6 gegenüberliegenden Seite des Rohres Lüftungsöffnungen vorhanden sind, um eine bessere Wärmeabfuhr aus dem Rohr zu ermöglichen.Instead of, as shown in FIG. 1, arranging a film forming the anti-glare body 10 within the tube 12, the tube itself can also have the prism structure according to the invention directly on its outer surface. It is also possible to arrange a film-like shielding body around the light source 1, which is fastened in the luminaire by corresponding holders. In the case of a closed, tubular shielding body or an arrangement of a foil-like shielding body, for example Within a tube, as shown in FIG. 1, it is expedient if there are ventilation openings on the side of the tube opposite the outlet opening 6 in order to enable better heat dissipation from the tube.

Die erfindungsgemäße Lösung basiert darauf, daß durch eine vorausberechnete Kombination von Brechung und Totalreflexion erreicht wird, daß das Licht aus bestimmten Winkelbereichen abgelenkt wird, um auf diese Weise eine Blendgefahr zu vermeiden. Die erfindungsgemäße optische Struktur besteht aus klarem Material, d.h. es handelt sich um ein Material, das Licht stark durchläßt, so daß ein hoher Wirkungsgrad der erfindungsgemäßen Leuchte gegeben ist.The solution according to the invention is based on the fact that a pre-calculated combination of refraction and total reflection ensures that the light is deflected from certain angular ranges in order to avoid the risk of glare. The optical structure according to the invention consists of clear material, i.e. it is a material that allows light to pass through, so that the luminaire according to the invention is highly efficient.

Aus den Figuren sind die geltenden Winkelbeziehungen zu erkennen, hierbei sind

α₁ =
Einfallswinkel des Lichtstrahls von der Lichtquelle,
α₂ =
Grenzwinkel der Totalreflexion
α₃ =
halber Spitzenwinkel der Prismen
Da α₃ = 45° ist, ergibt sich α₂ = ½ α₁.The applicable angular relationships can be seen from the figures
α₁ =
Angle of incidence of the light beam from the light source,
α₂ =
Limit angle of total reflection
α₃ =
half prism angle of the prisms
Since α₃ = 45 °, there is α₂ = ½ α₁.
