Description

Die Erfindung betrifft eine Blendschutzeinrichtung mit mehreren mit Abstand voneinander übereinander angeordneten, länglichen Lichtumlenklamellen, die auf ihren Oberseiten verspiegelt und im Querschnitt vorzugsweise konkav nach oben gewölbt sind.The invention relates to a glare protection device with several at a distance elongated light deflection slats arranged one above the other, on their Mirrored tops and preferably curved concave upwards in cross section are.

Die insbesondere am Arbeitsplatz vor allem bei Verwendung von Bildschirmen störenden hohen Fensterleuchtdichten bzw. die daraus resultierenden Blendungen rühren im allgemeinen einerseits von der hohen Himmelsleuchtdichte her, die auch bei verdeckter Sonne auftreten kann, und andererseits von Reflexionen der Himmelsstrahlung, zu der natürlich auch das direkte Sonnenlicht zählt, an anderen Gebäuden oder am beispielsweise schneebedeckten Boden. Jedenfalls ist das in der Praxis auf eine Fensteröffnung auftreffende Licht im allgemeinen diffus (d.h. es trifft von allen möglichen Richtungen auf), wobei klarerweise aus bestimmten Richtungen (etwa der Sonne oder der einer weißen Wand gegenüber) höhere Leuchtdichten zu erwarten sind als aus anderen.The especially in the workplace especially when using screens annoying high window luminance or the resulting glare generally originate on the one hand from the high sky luminance, which also hidden sun, and reflections of sky radiation, which of course also includes direct sunlight on other buildings or on, for example, snow-covered ground. Anyway, that's up in practice light hitting a window opening is generally diffuse (i.e. it hits everyone possible directions), clearly from certain directions (e.g. the Sun or that of a white wall) higher luminance can be expected are than from others.

Zugezogene Vorhänge und übliche Lamellenstores mit geschlossenen Lamellen bringen zwar eine zufriedenstellende Reduzierung der Fensterleuchtdichte; dies jedoch nur auf Kosten einer wesentlichen Reduzierung der in den Raum gebrachten Lichtmenge, sodaß oft auch am Tag künstliche Beleuchtungen nötig sind.Drawn curtains and usual slat blinds with closed slats bring a satisfactory reduction in window luminance; this however only at the expense of a substantial reduction in the amount brought into the room Amount of light, so that artificial lighting is often necessary even during the day.

Gute Blendschutzeinrichtungen zeichnen sich dadurch aus, daß sie einerseits unterhalb eines Grenzwinkels, im allgemeinen der Horizontalen (in speziellen Anwendungen sind aber andere Grenzwinkel möglich), nur wenig Licht in den Raum eintreten lassen und damit Blendungen etwa am Arbeitsplatz verhindern (Abblendbedingungen), anderseits insgesamt aber möglichst viel Lichtmenge durchlassen, um am Tag ohne künstliche Beleuchtung auszukommen. Dies läßt sich beispielsweise durch eine Blendschutzeinrichtung in Form einer aufziehbaren Lamellenjalousie mit oben verspiegelten und konkav nach oben gewölbten Lichtumlenklamellen erzielen, wie sie aus der EP-A2-0303107 bekannt ist.Good anti-glare devices are characterized by the fact that on the one hand below a critical angle, generally the horizontal (in special applications other limit angles are possible), only a little light can enter the room and thus prevent glare at work, for example (dimming conditions), on the other hand, as much as possible let through as much light as possible in order to be without get along with artificial lighting. This can be done, for example, by a Anti-glare device in the form of an openable slatted blind with the top achieve mirrored and concave upward-deflecting light deflection slats, as they do is known from EP-A2-0303107.

Aufgabe der Erfindung ist es, eine verbesserte Blendschutzeinrichtung der eingangs genannten Gattung zu schaffen, die bei Einhaltung der Abblendbedingungen für bestimmte Raumbereiche insgesamt eine hohe Lichtmenge in den Raum bringt und die andererseits einen gewissen Ausblick vom Raum durch die Blendschutzeinrichtung hindurch nach außen erlaubt. The object of the invention is to provide an improved anti-glare device at the beginning to create the above-mentioned genus, provided that the stopping down conditions are met certain areas of the room bring a large amount of light into the room and which on the other hand has a certain view from the room through the anti-glare device allowed outside through.

Diese Aufgabe wird erfindungsgemäß durch die Merkmale des Patentanspruchs 1 gelöst.This object is achieved by the features of claim 1 solved.

Die gelochte Ausbildung der Umlenklamellen erlaubt eine gewisse Teildurchsichtigkeit und ermöglicht somit vom Raum aus ein zumindest schemenhaftes Durchsehen nach außen. Gleichzeitig bleibt aber die gewünschte Abblendwirkung der Blendschutzeinrichtung erhalten. Die Unterseiten der Lichtumlenklamellen sind matt beschichtet oder lackiert, um Blendungen durch an den Unterseiten reflektierten Lichtstrahlen, die unter einem Winkel unter der Horizontalen h nach unten in den Raum eintreten, zu vermeiden. Gelochte Verdunkelungslamellen sind aus der EP-A-0 483 994 bekannt. Diese arbeiten jedoch nicht als Blendschutzeinrichtungen mit verspiegelten Oberseiten und matten Unterseiten.The perforated design of the deflection slats allows a certain degree of transparency and thus enables an at least vague look through from the room Outside. At the same time, however, the desired dimming effect remains Anti-glare device received. The undersides of the light deflection slats are matt coated or painted to prevent glare from reflecting on the undersides Rays of light coming down at an angle below the horizontal h Avoid entering space. Perforated blackout slats are from EP-A-0 483,994. However, these do not work as anti-glare devices mirrored tops and matt undersides.

Um den Wirkungsgrad der Blendschutzeinrichtung zu erhöhen, also insgesamt möglichst viel Licht von außen in den Raum zu bringen, ist es günstig, wenn die Lichtumlenklamellen nur auf einem sich in Lamellenlängsrichtung erstreckenden Streifen, der lediglich einen Teil der Lamellenbreite einnimmt, perforiert sind, während der restliche Teil der Lamellenbreite eine durchgehende geschlossene Oberfläche aufweist. Die geschlossene, verspiegelte Oberfläche ermöglicht eine nahezu vollständige Reflexion der auf sie auftreffenden Lichtstrahlen, während der bzw. die gelochten (perforierten) Bereiche naturgemäß etwas Licht verschlucken. Durch die nur teilweise Lochung der Lamellen kann man also über die geschlossenen Oberflächen einen hohen Wirkungsgrad und über die gelochten Bereiche dennoch eine gewisse Durchsichtigkeit erreichen.In order to increase the efficiency of the anti-glare device, overall Bringing as much light as possible into the room from the outside is beneficial if the Light deflecting slats only on one extending in the longitudinal direction of the slats Stripes that take up only part of the slat width are perforated while the remaining part of the slat width is a continuous closed surface having. The closed, mirrored surface enables an almost complete Reflection of the light rays hitting them, during the perforated Areas naturally swallow some light. Through the you can only partially perforate the slats the closed surfaces are highly efficient and nevertheless a certain one about the perforated areas Achieve transparency.

Besonders bei bevorzugten Ausführungsformen, bei der die einem Raum zugewandte, obere innere Längskante jeder Lichtumlenklamelle in Betriebsstellung höher als die dem Raum abgewandte, dazu parallele, obere äußere Längskante liegt, ist es günstig, wenn sich der perforierte Streifen der Länge nach über die gesamte Lichtumlenklamelle und der Breite nach vom in Betriebsstellung etwa tiefsten Bereich bis im wesentlichen hinauf zur inneren Längskante erstreckt. Damit ist der äußere Bereich der Lichtumlenklamelle, der zunächst vom Licht getroffen wird, mit einer geschlossenen verspiegelten Oberfläche versehen, welche eine verlustarme Reflexion erlaubt. Lediglich der nach hinten ansteigende und eigentlich den Ausblick nach außen verhindernde Bereich der Lichtumlenklamellen ist gelocht und erlaubt somit die gewünschte Durchsichtigkeit durch die Blendschutzeinrichtung von innen nach außen.Especially in preferred embodiments in which the upper inner longitudinal edge of each facing a room Light deflection slat in operating position higher than the upper, facing away from the room, parallel to it Long edge, it is beneficial if the perforated Stripe lengthways across the entire Light deflection slat and the width from in the operating position about the deepest range up to essentially extends to the inner longitudinal edge. So that's the outer area of the light deflection slat, which is initially from Light is struck with a closed mirrored Provide surface, which a low loss reflection allowed. Only the one that climbs backwards and actually the outlook-preventing area the light deflection slats are perforated and allowed thus the desired transparency through the anti-glare device from the inside to the outside.

Die Erfindung wird nachstehend anhand von Ausführungsbeispielen durch die Zeichnung näher erläutert.The invention is described below using exemplary embodiments explained in more detail by the drawing.

Es zeigen die Fig. 1 einen Raum mit einem vor Blendungen durch ein Fenster zu schützenden Arbeitsplatz, wobei eine von vielen möglichen Anordnungen der erfindungsgemäßen Blendschutzeinrichtung schematisch gezeigt ist, die Fig. 2 eine schematische Darstellung eines Ausführungsbeispiels der erfindungsgemäßen Blendschutzeinrichtung, die Fig. 3 einen schematischen Querschnitt durch vier Lichtumlenklamellen eines weiteren Ausführungsbeispiels, die Fig. 4 ein Ausführungsbeispiel einer erfindungsgemäßen Lichtumlenklamelle in perspektivischer Darstellung und die Fig. 5 einen Querschnitt durch zwei Lichtumlenklamellen eines weiteren Ausführungsbeispiels.1 shows a room with a glare workplace to be protected by a window, being one of many possible arrangements of the invention Anti-glare device shown schematically 2 is a schematic illustration of a Embodiment of the anti-glare device according to the invention, 3 shows a schematic cross section by four light deflection slats of a further exemplary embodiment, 4 shows an embodiment a light deflection slat according to the invention in perspective Representation and Fig. 5 is a cross section by two light deflection slats of a further embodiment.

In Fig. 1 ist ein in einem Teilbereich des Raumes 1 angeordneter Arbeitsplatz 2 gezeigt. Über eine als Fenster 3 ausgebildete Lichteintrittsöffnung gelangt Licht von außen in den Raum 1. Die innerhalb des Fensters 3 angeordnete Blendschutzeinrichtung 4 verhindert, daß die vom Arbeitsplatz aus wahrnehmbare Leuchtdichte des Fensters zu hoch ist und damit Blendungen hervorruft. Die Blendschutzeinrichtung 4 lenkt dabei beim gezeigten Beispiel von außen auftreffendes Licht in einen im wesentlichen über dem horizontalen Grenzstrahl h liegenden Winkelbereich um. Ein typischer Lichtstrahlenverlauf ist mit 1 bezeichnet.In Fig. 1 is arranged in a partial area of the room 1 Workplace 2 shown. Over one as a window 3 trained light entry opening gets light from outside into room 1. The inside of window 3 arranged anti-glare device 4 prevents the luminance of the Window is too high and thus causes glare. The anti-glare device 4 steers when shown Example of incident light in an essentially lying above the horizontal limit ray h Angular range around. A typical light beam path is denoted by 1.

Beim gezeigten Ausführungsbeispiel besteht die Blendschutzeinrichtung aus einer in Fig. 2 schematisch dargestellten hochziehbaren Lamellenjalousie 4, deren Lichtumlenklamellen 5 an ihren Oberseiten verspiegelt sind und vorzugsweise über ihre gesamte Länge konkav nach oben gewölbt sein können. Außerdem liegt zur Erzielung einer Lichtumlenkung in den oberen Halbraum die dem Raum 1 zugewandte innere Längskante 5a vorteilhaft gleich hoch (vgl. Fig. 5) oder höher (vgl. Fig. 3 und 4) als die äußere Längskante 5b. Ist kein Blendschutz nötig, so kann die Jalousie in die in Fig. 2 mit 4' bezeichnete Stellung hochgezogen werden.In the exemplary embodiment shown there is the anti-glare device from a schematically shown in Fig. 2 pull-up venetian blind 4, whose Light deflection slats 5 mirrored on their tops are and preferably concave over their entire length can be arched upwards. Also lies to achieve a redirection of light into the upper half space the inner longitudinal edge 5a facing the space 1 is advantageous same height (see Fig. 5) or higher (see Fig. 3 and 4) as the outer longitudinal edge 5b. Is not anti-glare necessary, the blind can be designated as 4 'in FIG. 2 Position to be pulled up.

In Fig. 3 sind vier übereinanderliegende Lichtumlenklamellen einer erfindungsgemäßen Blendschutzeinrichtung dargestellt. Selbstverständlich wird in der Praxis die Blendschutzeinrichtung mehr als vier übereinanderliegende Lichtumlenklamellen, im allgemeinen über die volle Fensterhöhe aufweisen. Die Lichtumlenklamellen 5 können über nicht dargestellte Aufziehschnüre od.dgl. nach Art einer Lamellenjalousie hochziehbar sein.In Fig. 3 are four superimposed light deflection slats an anti-glare device according to the invention shown. In practice, of course Anti-glare device more than four superimposed Light deflecting slats, generally via the have full window height. The light deflection slats 5 can or the like via pull cords, not shown. be pulled up like a slatted blind.

Die Oberseiten der Lichtumlenklamellen 5 sind verspiegelt und beim bevorzugten Ausführungsbeispiel durch eine hochglänzende Aluminiumoberfläche der aus Aluminium bestehenden Lichtumlenklamellen 5 gebildet. An den verspiegelten Oberflächen der Lichtumlenklamellen erfolgt im wesentlichen gerichtete Reflexion nach dem bekannten Reflexionsgesetz, wobei die verspiegelten Oberseiten der Lichtumlenklamellen einen Reflexionsgrad von mehr als 85 % bei einem Diffusanteil von weniger als 20 % aufweisen. Der Glanz der verspiegelten Oberseiten der Lichtumlenklamellen bei einem Einstrahlungswinkel von 60° beträgt mehr als 80 %.The tops of the light deflection slats 5 are mirrored and in the preferred embodiment a high-gloss aluminum surface made of aluminum existing light deflection slats 5 formed. To the mirrored surfaces of the light deflection slats essentially directed reflection according to the known Law of reflection, with the mirrored tops the light deflection slats have a reflectance of more than 85% with a diffuse content of less than Have 20%. The sheen of the mirrored Tops of the light deflecting louvers on one Beam angle of 60 ° is more than 80%.

Die Unterseiten der Lichtumlenklamellen sind matt beschichtet oder lackiert, um Blendungen durch an den Unterseiten reflektierten Lichtstrahlen, die unter einem Winkel unter der Horizontalen h nach unten in den Raum eintreten, zu vermeiden. Dabei ist es günstig, wenn der Reflexionsgrad der diffus reflektierenden Unterseiten der Lichtumlenklamellen zwischen 30 und 50 % liegt. Eine solche Ausbildung der Unterseiten wirkt sich auch günstig auf die vom Betrachter wahrnehmbare Teildurchsichtigkeit der Blendschutzeinrichtung von innen nach außen aus, welche im folgenden noch näher beschrieben werden wird. Die obigen Reflexionsgrad-Angaben beziehen sich auf die Oberflächenbereiche zwischen bzw. außerhalb der Löcher. The undersides of the light deflection slats are matt coated or painted to glare through on the undersides reflected rays of light falling under a Angle below the horizontal h down into the room to avoid. It is beneficial if the Degree of reflection of the diffusely reflecting undersides the light deflection slats is between 30 and 50%. Such a design of the sub-pages also has an effect favorable to the partial transparency perceivable by the viewer the anti-glare device from the inside out outside, which is described in more detail below will be. Obtain the above reflectance information on the surface areas between or outside of the holes.

Um durch die Blendschutzeinrichtung nach außen sehen zu können, sind die Lichtumlenklamellen 5 in sich in Lamellenlängsrichtung erstreckenden Streifen der Breite b durch eine Lochung perforiert, wie dies beispielsweise aus der Fig. 4 ersichtlich ist, die nur einen Teil der Lamellenlänge darstellt.To look out through the anti-glare device can, the Lichtumlenklamellen 5 in itself in the longitudinal direction of the slats extending strips of width b perforated through a perforation, such as this 4, which is only a part of the Represents slat length.

Der perforierte Streifen erstreckt sich der Länge nach über die gesamte Lichtumlenklamelle und in der Breite vom etwa tiefsten Punkt A bis im wesentlichen hinauf zur inneren Längskante 5a, die höher als die äußere Längskante 5b und beim gezeigten Ausführungsbeispiel in etwa auf der Höhe des tiefsten Punktes der darüberliegenden Lichtumlenklamelle liegt.The perforated strip extends lengthways over the entire light deflection slat and in width from approximately the lowest point A to essentially up to the inner longitudinal edge 5a, which is higher than the outer Longitudinal edge 5b and in the embodiment shown in at about the lowest point of the one above Light deflection slat lies.

Die Außenseiten der Lamellen weisen eine durchgehende verspiegelte Oberfläche in dem Bereich a auf und erlauben somit einen hohen Wirkungsgrad der Blendschutzeinrichtung. Aus herstellungstechnischen und optischen Gründen kann es günstig sein, wenn der an die innere Längskante 5a der Lichtumlenklamelle 5 angrenzende Bereich c auf eine Breite von vorzugsweise einigen Millimetern eine durchgehende, also nicht perforierte Oberfläche aufweist.The outside of the slats have a continuous mirrored surface in area a and allow thus a high efficiency of the anti-glare device. From manufacturing and optical For reasons, it may be beneficial if the on the inside Longitudinal edge 5a of the light deflecting lamella 5 adjacent area c to a width of preferably a few millimeters a continuous, not perforated surface having.

Die Lochung kann vorteilhaft von einem regelmäßigen Muster von in Draufsicht kreisrunden Löchern durch die Lichtumlenklamellen gebildet sein, wie dies in Fig. 4 dargestellt ist. Dabei können die Löcher 6 vorteilhaft in Lamellenlängsrichtung verlaufenden Lochreihen angeordnet sein, die gegeneinander versetzt sind und somit eine möglichst gleichmäßige Lochung ergeben. Herstellungstechnisch können die Löcher 6 beispielsweise durch Ausstanzen oder Bohren ausgebildet werden. The punching can be advantageous from a regular one Pattern of circular holes through the top view Light deflection slats can be formed, as shown in FIG. 4 is shown. The holes 6 can be advantageous Arranged rows of holes running in the longitudinal direction of the slats be offset from each other and thus perforation should be as uniform as possible. Manufacturing technology can the holes 6 for example be formed by punching or drilling.

Zusammen mit dem Reflexionsgrad der Lamellenunterseite bestimmen die Lochgröße und der Lochanteil wesentlich die Durchsichtigkeit durch die Blendschutzeinrichtung. Durch einen höheren Lochanteil kann beispielsweise die Durchsichtigkeit von innen nach außen durch die Blendschutzeinrichtung hindurch erhöht werden. Allerdings sinkt damit auch der Wirkungsgrad, also die insgesamt in den Raum gebrachte Lichtmenge. Als günstiger Kompromiß hat sich ein Lochanteil der perforierten Bereiche der Lichtumlenklamellen zwischen 15 und 30 %, vorzugsweise zwischen 15 und 20 % herausgestellt. Der Lochanteil ist dabei als Verhältnis der gesamten Oberfläche der Löcher 6 in Draufsicht zu der zwischen den Löchern liegenden Oberfläche des Streifens der Breite b definiert. Herstellungstechnisch und optisch ist es günstig, wenn der maximale Lochdurchmesser weniger als 2 mm, vorzugsweise weniger als 1 mm beträgt.Together with the reflectivity of the underside of the slats determine the hole size and the proportion of holes significantly the transparency through the anti-glare device. With a higher percentage of holes, for example Transparency from the inside out through the anti-glare device be increased through. Indeed this also reduces the overall efficiency amount of light brought into the room. As a cheap compromise there is a hole portion of the perforated areas the light deflection slats between 15 and 30%, preferably between 15 and 20%. The percentage of holes is the ratio of the total surface of the holes 6 in plan view to that between the holes lying surface of the strip of width b defined. In terms of production technology and optics, it is favorable if the maximum hole diameter is less than 2 mm, preferably less than 1 mm.

In Fig. 5 sind zwei Lichtumlenklamellen 5 eines Ausführungsbeispiels schematisch im Querschnitt dargestellt. Die Lamellenbreite beträgt im konkret vorliegenden Fall 80 mm und der Lamellenabstand 11 mm. Die äußere Längskante 5b liegt gleich hoch wie die innere (raumseitige) Längskante 5a. Der am tiefsten unter der Horizontalen ohne Reflexion eintretende direkte Lichtstrahl l1 schließt einen nur kleinen negativen Grenzwinkel β mit der Horizontalen X ein. Die Lichtumlenklamellen 5 sind - im Querschnitt gesehen - Teile von Ellipsen der Brennpunkte F1, F2 auf den Längskanten 5a, b der jeweils darüberliegenden Lichtumlenklamelle. Damit treten nahezu alle von außen auf die verspiegelte Lamellenoberseite auftreffenden Strahlen mit nur einer Reflexion unter Einhaltung der Abblendbedingung in den Raum 1 ein. Vom tiefsten Punkt A bis etwa zur inneren Längskante 5a sind die Lichtumlenklamellen gelocht und erlauben somit auch von leicht schräg unten einen gewissen Durchblick nach außen.In Fig. 5, two light deflection slats 5 of an embodiment are shown schematically in cross section. The slat width in the present case is 80 mm and the slat distance 11 mm. The outer longitudinal edge 5b is the same height as the inner (room-side) longitudinal edge 5a. The direct light beam l 1 entering deepest below the horizontal without reflection includes only a small negative critical angle β with the horizontal X. Seen in cross section, the light deflection slats 5 are parts of ellipses of the focal points F 1 , F 2 on the longitudinal edges 5a, b of the light deflection slat lying above them. This means that almost all of the rays that strike the mirrored top of the slats from outside enter room 1 with only one reflection, while maintaining the dimming conditions. From the lowest point A to approximately the inner longitudinal edge 5a, the light deflection slats are perforated and thus also allow a certain view outwards from slightly obliquely below.

Die Lichtumlenklamellen können in einer unverschwenkbaren fixen Lage aufgehängt sein, die sie bei herabgelassener Lamellenjalousie automatisch einnehmen. Eine verschwenkbare Aufhängung der Lichtumlenklamellen ist jedoch auch durchaus denkbar und möglich.The light deflecting slats can be in a non-pivoting fixed position, which they are lowered Take the slatted blind automatically. A swiveling one Suspension of the light deflection slats is however also conceivable and possible.

Die Erfindung ist selbstverständlich nicht auf die dargestellten Ausführungsbeispiele beschränkt. Beispielsweise kann sich der gelochte Bereich über einen größeren Bereich der Lamellenbreite erstrecken, als dies in Fig. 4 dargestellt ist. Es sind auch mehrere gesonderte gelochte Lamellenbereiche denkbar und möglich. Die Lochung muß auch nicht in dem in Fig. 4 dargestellten Muster angeordnet sein. Auch brauchen die Löcher nicht notwendigerweise kreisrund zu sein. Vielmehr können beispielsweise auch in der Draufsicht quadratische Löcher vorgesehen sein, um die Lichtumlenklamellen zu perforieren.The invention is of course not limited to that shown Embodiments limited. For example the perforated area can spread over a larger area Range of slat widths than this in Fig. 4 is shown. There are also several separate ones perforated slat areas conceivable and possible. The Punching also need not be shown in FIG. 4 Pattern. The holes don't need either necessarily to be circular. Rather you can for example square holes in plan view be provided to the light deflection slats perforate.

Claims (16)

  1. Anti-glare fitment with a plurality of elongate light-deflecting slats (5) which are arranged one above another, at a distance from each other, and which are reflective on their upper surface and preferably have a cross section which is upwardly curved in a concave manner, characterised in that the light-deflecting slats (5) are, at least within an area (b), perforated, and that the undersides of the light-deflecting slats (5) are diffusely reflecting matt coated or matt painted.
  2. Anti-glare fitment according to claim 1, characterised in that the light-deflecting slats (5) are only perforated in a stripe, running along the longitudinal direction of the slats, which merely takes up part (b) of the width of the slat, while the remaining part (a, c) of the width of the slat has a continuously closed upper surface.
  3. Anti-glare fitment according to claims 1 or 2, characterised in that the upper, inner, longitudinal edge (5a) of each light-deflecting slat (5), which faces into a room (1), is higher in its operating position than the upper, outer longitudinal edge (5b) which is parallel thereto and faces away from the room (1).
  4. Anti-glare fitment according to claim 2 and claim 3, characterised in that the perforated stripe extends longitudinally along the entire light-deflecting slat (5) and widthwise in the area (b) from approximately the lowest point (A) in the operating position upwards substantially to the inner longitudinal edge (5a).
  5. Anti-glare fitment according to one of claims 1 to 4, characterised in that the area which borders the inner longitudinal edge (5a) of the light-deflecting slat (5) is provided with a continuous, unperforated surface, preferably a few millimetres in width (c).
  6. Anti-glare fitment according to one of claims 1 to 5, characterised in that the perforation is made through the light-deflecting slats (5) in a preferably regular pattern of perforations (6) which are circular viewed from above.
  7. Anti-glare fitment according to claim 6, characterised in that the perforations (6) are arranged in rows along the longitudinal direction of the slats.
  8. Anti-glare fitment according to one of claims 1 to 7, characterised in that the maximum diameter of the perforations (6) which form the perforation is less than 2 mm, and preferably less than 1 mm.
  9. Anti-glare fitment according to one of claims 1 to 8, characterised in that the percentage of perforation in the perforated areas (b) of the light-deflecting slats (5) is between 10% and 30%, and preferably between 15% and 20%.
  10. Anti-glare fitment according to one of claims 1 to 9, characterised in that the reflective upper surfaces of the light-deflecting slats (5) are in a manner known per se formed by a high-gloss metallic surface, preferably an aluminium surface.
  11. Anti-glare fitment according to one of claims 1 to 10, characterised in that the reflective upper surfaces of the light-deflecting slats (5) have a reflection factor of more than 85% with a diffusion component of less than 20%.
  12. Anti-glare fitment according to one of claims 1 to 11, characterised in that the brightness of the reflective upper surface of the light-deflecting slats (5) at an incident angle of 60° is more than 80%.
  13. Anti-glare fitment according to one of claims 1 to 12, characterised in that the reflection factor of the diffusely reflecting undersides of the light-deflecting slats (5) is between 30% and 50%.
  14. Anti-glare fitment according to one of claims 1 to 13, characterised in that the light-deflecting slats (5) are - in a manner known per se - hung in a non-tilting, fixed position, which they take up when the slatted blind (4) is in the lowered position.
  15. Anti-glare fitment according to one of claims 1 to 14, characterised in that at least a part of the light-deflecting slats (5) - viewed in cross-section - has a substantially elliptical profile, a focal point (F1) of the elliptical part lying in the region of the outer longitudinal edge (5b) of the light-deflecting slat lying on top thereof, preferably lying on this longitudinal edge (5b), and the second focal point (F2) lying in the area of the inner longitudinal edge (5a) of the light-deflecting slat lying on top thereof.
  16. Anti-glare fitment according to one of claims 1 to 15, characterised in that each light-deflecting slat (5) extends into the interior of the room (1), a horizontal plane which includes the inner, upper, longitudinal edge (5a) of a light-deflecting slat (5) just forming a tangential plane to the underside of the slat (5) lying on top thereof.
