Description

Die Erfindung betrifft eine Leuchte mit einer Lampe, mit einem dieser zugeordneten Reflektor zum Erzeugen eines um eine Hauptstrahlungsrichtung verteilten Lichtbündels und mit einer transparenten Linsenanordnung zum Verteilen eines Teiles des von der Lampe ausgehenden Lichts.The invention relates to a lamp with a lamp, with one associated with it Reflector for generating a light beam distributed around a main radiation direction and with a transparent lens arrangement for distributing a portion of the Lamp outgoing light.

Grundsätzlich ist es bereits bekannt, unterhalb von sogenannten Downlights, das sind in der Decke integrierte Deckenleuchten, meist mit Halogenlampen, Reflektoren bzw. eine Linsenanordnung anzuordnen.Basically, it is already known below what are known as downlights ceiling lights integrated in the ceiling, mostly with halogen lamps, reflectors or to arrange a lens arrangement.

Downlights erzeugen im Normalfall eine sehr steil nach unten gehende Lichtverteilung, wobei die Hauptstrahlungsrichtung im wesentlichen vertikal ist. Um nicht nur hohe Horizontal- sondern auch Vertikalbeleuchtungsstärken zu erreichen (günstig wäre ein Verhältnis von mindestens 3:1, besser 3:2), sollte die Leuchte auch sehr flach bzw. horizontal austretende Lichtstrahlen aufweisen. Diese Lichtstrahlen verursachen aber im allgemeinen eine starke Blendung, welche unerwünscht ist.Downlights normally produce a very steep downward light distribution, the main radiation direction being substantially vertical. To not only high To achieve horizontal but also vertical illuminance levels (one would be cheap Ratio of at least 3: 1, better 3: 2), the lamp should also be very flat or have horizontally emerging light beams. But these light rays cause generally severe glare, which is undesirable.

Erfindungsgemäß wird nun vorgesehen, daß die Linsenanordnung mehrere um die Hauptstrahlungrichtung herum, vorzugsweise ringförmig verteilte Linsen aufweist.According to the invention it is now provided that the lens arrangement several by Main radiation direction around, preferably annularly distributed lenses.

Durch diese Maßnahme ist es möglich, die Blendung stark zu reduzieren bzw. aufzuheben, weil das Abbild der Lichtquelle (Lampe) über die einzelnen Linsen in viele kleine Lichtpunkte über die gesamte sichtbare Fläche zerlegt wird (Lichtpunktzerlegung). In der Praxis sollte die Linsenzahl größer als 30, vorzugsweise sogar größer als 100 sein.This measure makes it possible to greatly reduce glare or cancel because the image of the light source (lamp) over the individual lenses in many small points of light are broken down over the entire visible area (Light point decomposition). In practice, the number of lenses should be greater than 30, preferably be even larger than 100.

Die Lichtstärke geht somit nicht von einer Stelle der sichtbaren Lichtaustrittsfläche aus, sondern von sehr vielen und sehr kleinen in Abständen zueinander angeordneten Lichtpunkten (vorzugsweise kleiner als 2 x 2 mm) der einzelnen Linsen. Damit ist es möglich, auch flach austretende Lichtstrahlen mit einer hohen vertikalen Beleuchtungsstärke zu haben und gleichzeitig die Blendwirkung zu vermeiden. Man erzielt somit auch bei Downlights eine Decken- und Wandaufhellung. The light intensity therefore does not start from a point on the visible light exit surface, but from very many and very small ones spaced apart Light spots (preferably smaller than 2 x 2 mm) of the individual lenses. So that's it possible, even flat emerging light rays with a high vertical To have illuminance while avoiding glare. Man achieves ceiling and wall illumination even with downlights.

Besonders günstig ist eine Ausführungsform bei der die um die Hauptstrahlungsrichtung herum verteilten Linsen nicht einzelne gesonderte Linsen sind, sondern diese Linsen an einem einstückigen, vorzugsweise ringförmigen Linsenkörper ausgebildet sind. Die Linsenwirkung kann dabei beim ringförmigen Linsenkörper dadurch zustande kommen, daß dieser an seiner Innenseite mehrere konkave Einbuchtungen aufweist, wobei jede dieser Einbuchtungen eine eigene Linsenfläche bildet.An embodiment in which the order is particularly favorable Lenses distributed around the main radiation direction did not separate individual lenses are, but these lenses on a one-piece, preferably ring-shaped Lens body are formed. The lens effect can be ring-shaped Lens body come about by the fact that there are several on its inside has concave indentations, each of these indentations having its own Lens surface forms.

Außerdem ist es günstig, wenn nicht nur ein ringförmiger Linsenkörper vorgesehen ist, sondern die Linsen auch im wesentlichen entlang der Hauptstrahlungsrichtung verteilt sind. Bei der bevorzugten Deckenleuchte sind also dann mehrere mit Abstand zueinander angeordnete Linsenkörper, insbesondere ringförmige Linsenkörper untereinander gestapelt vorgesehen. Damit läßt sich eine noch feingliedrigere Lichtpunktzerlegung vornehmen. Die Blendwirkung wird weiter reduziert bzw. die Vertikalbeleuchtungsstärke erhöht.In addition, it is advantageous if not only an annular lens body is provided, but also the lenses are essentially distributed along the main radiation direction are. In the preferred ceiling lamp, there are several at a distance lens bodies arranged with respect to one another, in particular annular lens bodies provided stacked one below the other. This allows an even more delicate one Carry out light point decomposition. The glare is further reduced or the Vertical illuminance increased.

Durch den Stapel von übereinander liegenden Linsenkörpern wird außerdem der direkte Einblick in die Lampe nur unter sehr steilem Winkel möglich. Die Linsen bzw. Linsenkörper können so angeordnet und dimensioniert sein, daß der der Lampe zugeordnete (Haupt) Reflektor um einen großen Teil des Lampenlichtstroms mit Hilfe eines konvergenten Strahlungsprinzips entsprechend der Beleuchtungsaufgabe in einem definierten Raumwinkel nach unten verteilt, und zwar so, daß er am Linsenmaterial vorbei durch das Innere der ringförmigen Linsenkörper frei austritt. Die restliche Strahlung der Lampe, die durch diesen (Haupt) Reflektor nicht mehr aufgefangen wird, nämlich der sogenannte Direktstrahlungsanteil, trifft auf die im bevorzugten Ausführungsbeispiel übereinander liegenden ringförmigen Linsenkörper, die das Licht durch Brechung so zerlegen und umlenken, daß die gewünschte Lichtpunktzerlegung mit hohen Vertikalbeleuchtungsstärken erzielt wird.Through the stack of superimposed lens bodies, the direct view of the lamp is only possible at a very steep angle. The lenses or Lens bodies can be arranged and dimensioned so that the lamp assigned (main) reflector using a large part of the lamp luminous flux of a convergent radiation principle according to the lighting task in a defined solid angle downwards, so that it is on Lens material passes freely through the interior of the annular lens body. The residual radiation from the lamp, no longer through this (main) reflector is caught, namely the so-called direct radiation component, meets the im preferred embodiment superimposed annular lens body, which break up and deflect the light by refraction in such a way that the desired light point decomposition is achieved with high vertical illuminance.

    • Further advantages and details of the invention are explained in more detail with reference to the following description of the figures.
  • 1 shows a vertical section through an embodiment of a lamp according to the invention,
  • 2 shows the (main) reflector and the lens arrangement of a lamp according to the invention,
  • 3 shows a top view of a single annular lens body of the lens arrangement,
  • 4 shows a schematic beam path of a lamp according to the invention.

    • Bei der in Fig. 1 dargestellten Leuchte handelt es sich um ein sogenanntes Downlight, das in einer Decke 11 eingebaut ist. Die Leuchte weist in einem Leuchtengehäuse 1 einen Reflektor 2 und eine Lampe 3 auf. Der Reflektor 2 erzeugt als Reflexionsstrahlungsanteil der Leuchte ein Lichtbündel, das um die hier vertikal nach unten gerichtete Hauptstrahlungsrichtung 4 verteilt ist (vgl. auch Fig. 4).The lamp shown in FIG. 1 is a so-called downlight, that is installed in a ceiling 11. The lamp has a lamp housing 1 a reflector 2 and a lamp 3. The reflector 2 generated as Reflecting radiation portion of the luminaire is a beam of light that is vertically oriented around the here main radiation direction 4 directed below is distributed (cf. also FIG. 4).

    Unterhalb der Decke 11 ist eine Linsenanordnung 5 vorgesehen, die erfindungsgemäß mehrere um die Hauptstrahlungsrichtung verteilte Linsen 6 aufweist.Below the ceiling 11, a lens arrangement 5 is provided, which according to the invention has a plurality of lenses 6 distributed around the main radiation direction.

    Diese Linsen sind an jeweils einstückigen Linsenkörpern 7 ausgebildet, wobei beim dargestellten Ausführungsbeispiel 6 mit Abstand übereinander angeordnete Linsenkörper vorgesehen sind. Dies ist insbesondere aus den Figuren 1 und 2 ersichtlich.These lenses are each formed on one-piece lens bodies 7, with the Embodiment 6 shown spaced one above the other Lens bodies are provided. This is particularly evident from FIGS. 1 and 2 evident.

    Jeder dieser einstückigen Linsenkörper, der beispielsweise aus Glas oder durchsichtigem Kunststoff bestehen kann, ist um die Hauptstrahlungsrichtung 4 herum ringförmig ausgebildet.Each of these one-piece lens bodies, for example made of glass or transparent plastic can exist around the main radiation direction 4 ring-shaped.

    Die einzelnen Linsen 6 werden dadurch gebildet, daß der Linsenkörper an seiner, der Hauptstrahlungsrichtung 4 zugewandten Innenseite mehrere konkave Einbuchtungen 6a aufweist, wobei jede dieser Einbuchtungen eine eigene Linsenfläche einer Zerstreulinse bildet (vgl. Fig. 3).The individual lenses 6 are formed in that the lens body on its, the Main radiation direction 4 facing inside several concave indentations 6a, each of these indentations having its own lens surface Dispersion lens forms (see. Fig. 3).

    An seiner Außenseite ist der Linsenkörper 7 jeweils zylindrisch ausgebildet, was es erlaubt, einen Glaszylinder 8 als Staubschutz knapp herumzuführen, wobei dieser vorzugsweise an den Stellen 9 mit dem untersten Linsenkörper 7 staubdicht verklebt ist. Zum selben Zweck dient eine horizontale Glasplatte 10, die ebenfalls mit dem untersten Ring verklebt ist. On the outside, the lens body 7 is cylindrical, whichever it is allows a glass cylinder 8 as dust protection to run around, this preferably glued dust-tight at the points 9 to the lowermost lens body 7 is. For the same purpose serves a horizontal glass plate 10, which also with the bottom ring is glued.

    Im übrigen ist zu erwähnen, daß die mechanischen Halteelemente für die Linsenkörper in den Figuren nicht dargestellt sind. Es kann sich dabei beispielsweise um dünne Stäbe oder Seile handeln. Es können aber auch durchsichtige Halteelemente vorgesehen werden.It should also be mentioned that the mechanical holding elements for the lens body are not shown in the figures. For example, it can be thin Trade rods or ropes. But it can also be transparent holding elements be provided.

    Was die Form der einzelnen Linsenkörper betrifft, so sind die Deckflächen 7a und Grundflächen 7b jedes Linsenkörpers jeweils Teile einer Kegelfläche, wobei der gedachte Kegel mit seiner Spitze nach oben zur Lampen-Reflektor-Kombination 2, 3 hinweist.
    Mit einer derartigen Anordnung läßt sich insgesamt eine Lichtverteilung erzielen, wie sie im wesentlichen in der Fig. 4 dargestellt ist. Der vom Reflektor 2 reflektierte Reflexionsstrahlungsanteil tritt als zunächst konvergentes und dann divergentes Lichtstrahlungsbündel 12 (Reflexionsstrahlungsanteil) aus der Leuchte aus, und zwar im wesentlichen ungehindert durch die Linsenanordnung 5, also einfach zwischen den rinförmigen Linsenkörpern 7 hindurch. Ein Teil des Direktstrahlungsanteils der Lampe 3, der nicht auf den Reflektor 2 fällt, gelangt auf die Linsen des Linsenkörpers und wird von diesen flach nach außen umgelenkt. Ein Teil des so umgelenkten Strahlenganges ist in der Fig. 4 mit 13 bezeichnet. Wesentlich ist dabei der erfindungsgemäße Effekt der Zerlegung der Lampe in einzelne Lichtpunkte durch die vielen zirkumverial verteilten Linsen 6, die es ermöglichen, flache Lichtstrahlen zu haben, ohne dabei eine Blendwirkung in Kauf nehmen zu müssen.    As far as the shape of the individual lens bodies is concerned, the top surfaces 7a and base surfaces 7b of each lens body are each parts of a conical surface, the imaginary cone pointing upwards to the lamp-reflector combination 2, 3.
    With such an arrangement, overall a light distribution can be achieved, as is shown essentially in FIG. 4. The reflection radiation component reflected by the reflector 2 emerges from the lamp as an initially convergent and then divergent light radiation beam 12 (reflection radiation component), essentially unimpeded through the lens arrangement 5, i.e. simply between the ring-shaped lens bodies 7. A part of the direct radiation portion of the lamp 3, which does not fall on the reflector 2, reaches the lenses of the lens body and is deflected flatly outwards by them. A part of the beam path deflected in this way is designated by 13 in FIG. 4. What is essential here is the effect according to the invention of breaking down the lamp into individual light points through the many circumferentially distributed lenses 6, which make it possible to have flat light rays without having to put up with a glare effect.

    Die Erfindung ist selbstverständlich nicht auf das dargestellte Ausführungsbeispiel beschränkt, beispielsweise kann der Aufbau und die Zahl der Linsenkörper variieren. Insbesondere sind auch einzelne gesonderte Linsen möglich. Wesentlich ist - wie bereits erwähnt - die Lichtpunktzerlegungswirkung der vielen Linsen, die es erlaubt, flache horizontale Strahlen ohne Blendwirkung zu haben.The invention is of course not limited to the exemplary embodiment shown, for example, the structure and number of lens bodies can vary. In particular, individual separate lenses are also possible. It is essential - how already mentioned - the light point decomposition effect of the many lenses, which allows flat horizontal rays without glare.
