Description

Beleuchtungseinrichtung Lighting device
Die Erfindung betrifft eine Beleuchtungseinrichtung, welche ei- nen eine Nut aufweisenden Teil, eine in der Nut angeordnete Lichtquelle, und eine lichtdurchlässige Abdeckung umfasst. Die Erfindung liegt vor allem in der Ausbildung der lichtdurchlässi- gen Abdeckung, und die Beleuchtungseinrichtung ist besonders vorteilhaft mit einer Möbelplatte kombinierbar. The invention relates to a lighting device which comprises a part having a groove, a light source arranged in the groove, and a translucent cover. The invention lies primarily in the design of the translucent cover, and the lighting device can be particularly advantageously combined with a furniture panel.
Beispielsweise an Möbeln wird eine Beleuchtung durch eine bevor- zugt streifenförmige Lichtquelle verwirklicht, welche in eineFor example, on furniture, lighting is achieved by a preferably strip-shaped light source, which is in a
Nut eingelegt ist, und durch die offene Querschnittsflächenseite der Nut aus dieser heraus leuchtet. Typischerweise aber nicht notwendigerweise ist dabei die streifenförmige Lichtquelle durch ein sogenanntes LED-Lichtband realisiert. Bei einem solchen sind Leuchtdioden in kurzen Abständen zueinander entlang eines fle- xiblen Bandes angeordnet und gemeinsam mit elektrischer Energie versorgt. Üblicherweise ist die streifenförmige Lichtquelle zur offenen Querschnittsflächenseite der besagten Nut hin durch eine lichtdurchlässige Abdeckung abgedeckt. Die lichtdurchlässige Ab- deckung hat optische Funktionen sowie diverse Schutzfunktionen inne. Groove is inserted and shines out through the open cross-sectional surface side of the groove. Typically, but not necessarily, the strip-shaped light source is implemented by a so-called LED light strip. In such a system, light-emitting diodes are arranged at short distances from one another along a flexible band and are jointly supplied with electrical energy. Typically, the strip-shaped light source is covered by a translucent cover towards the open cross-sectional surface side of said groove. The translucent cover has optical functions as well as various protective functions.
Neben der Lichtdurchlässigkeit können durch die Abdeckung weite- re optische Funktionen wie beispielsweise eine Art Linsenwirkung (geordnetes Verengen oder Verbreitern des durchtretenden Licht- bündels), eine farbliche Veränderung des durchgeleiteten Lich- tes, oder eine diffuse Streuung des durchgeleiteten Lichtes er- füllt werden. In addition to light transmission, the cover can fulfill other optical functions such as a type of lens effect (orderly narrowing or widening of the light beam passing through), a color change of the transmitted light, or a diffuse scattering of the transmitted light.
Die DE 10 2011 008 560 Al zeigt eine Möbelplatte, welche auch Beleuchtungseinrichtung ist. Entlang einer Stirnseite der Möbel- platte verläuft eine Nut, in welche als eine Art Auskleidung ein metallisches Nutprofil eingesetzt ist, aann dessen Nutgrund ein LED-Lichtband verläuft. Die offene Profilseite Nutprofils ist durch ein weiteres Profil abgedeckt, welches die Querschnitts- form eines flachen Rechteckes hat, und aus transparentem oder transluzentem Glas oder polymerem Material besteht. Das abde- ckende Profil überbrückt die beiden Flanken des Nutprofils. An der einen Nutprofilflanke iisstt es gehalten, indem eess in eine kleine Nut an der Profilflanke hineinragt. An der zweiten Nut- profilflanke ist das abdeckende Profil durch ein sog. Klemmele- ment gehalten, welches ein elastisch verformbares, annähernd fa- denförmig schlankes separates Profil aus einem elastomeren Mate- rial sein dürfte, und unter elastischer Verformung seiner selbst in einen schmalen Spalt zwischen besagter zweiter Nutprofilflan- ke und einer langen Stirnfläche des abdeckenden Profils hinein- gequetscht ist. DE 10 2011 008 560 Al shows a furniture panel, which is also a lighting device. A groove runs along one end face of the furniture panel, into which a metallic groove profile is inserted as a kind of lining, along the bottom of which an LED light strip runs. The open profile side is the groove profile covered by another profile, which has the cross-sectional shape of a flat rectangle and consists of transparent or translucent glass or polymeric material. The covering profile bridges the two flanks of the groove profile. It is held on one groove profile flank by protruding into a small groove on the profile flank. On the second groove profile flank, the covering profile is held by a so-called clamping element, which is likely to be an elastically deformable, approximately thread-like, slim separate profile made of an elastomeric material, and elastically deforms itself into a narrow gap is squeezed between said second groove profile flank and a long end face of the covering profile.

Flanken der Nut anliegt und dadurch in der Nut gehalten wird. Flanks of the groove rests and is thereby held in the groove.
Die der Erfindung zu Grunde liegende Aufgabenstellung besteht darin, eine Beleuchtungseinrichtung, welche einen eine Nut auf- weisenden Teil, eine entlang des Nutgrundes der Nut verlaufende Lichtquelle und eine Abdeckung für die Lichtquelle umfasst, ge- genüber der aus der CN 212029216 U bekannten Bauweise dahinge- hend zu verbessern, dass sie noch bei der Montage eine Wählbar- keit von optischen Eigenschaften zulässt. The object on which the invention is based is to provide a lighting device which comprises a part having a groove, a light source running along the bottom of the groove and a cover for the light source, compared to the design known from CN 212029216 U - to be improved so that it allows for a selection of optical properties during assembly.
Für das Lösen der Aufgabenstellung wird von der bekannten Merk- malskombination ausgegangen, wonach die Beleuchtungseinrichtung einen Gegenstand umfasst, entlang dessen Oberfläche eine Nut verläuft, entlang deren Nutgrund eine langgestreckte Lichtquelle verläuft und wonach die Lichtquelle durch eine langgestreckte transparente oder transluzente Abdeckung aus einem elastomeren Material abgedeckt ist, welche in der Nut in einem Abstand zum Nutgrund entlang verläuft, den Raum zwischen den beiden Nutflan- ken überbrückt, wobei die Elastizität des Materials und die Ab- messungen der (zur Längsrichtung normal liegenden) Querschnitts- fläche dazu bemessen sind, dass die Abdeckung in einer normal zu ihrer Längsrichtung liegenden Richtung durch elastische Kompres- sion zerstörungsfrei ssoo weit komprimierbar ist, dass sie zwi- schen den Flanken der Nut Platz ffiinnddeett,. und an den Flanken derTo solve the problem, the known combination of features is assumed, according to which the lighting device comprises an object, along the surface of which a groove runs, along the bottom of the groove an elongated light source runs and after which the light source passes through an elongated transparent or translucent cover made of an elastomeric material is covered, which is in the groove at a distance from the runs along the bottom of the groove, bridging the space between the two groove flanks, whereby the elasticity of the material and the dimensions of the cross-sectional area (normal to the longitudinal direction) are dimensioned so that the cover passes through in a direction normal to its longitudinal direction elastic compression can be compressed non-destructively to such an extent that there is space between the flanks of the groove. and on the flanks of the
Nut unter elastischer DruckvorSpannung anliegt, und ihre Längs- richtung dabei parallel zur Längsrichtung der Nut liegt. Groove rests under elastic compressive preload, and its longitudinal direction is parallel to the longitudinal direction of the groove.
Als erfindungsgemäße Weiterentwicklung dazu wird vorgeschlagen, die Abdeckung weiters mit der Kombination der folgenden beiden Merkmale auszubilden: As a further development according to the invention, it is proposed to further design the cover with the combination of the following two features:
Merkmal 1: Feature 1:
Die Abdeckung weist mindestens zwei Paare von gegenüberliegenden Mantelflächenseiten auf, welche bei elastisch entspannter Abde- ckung voneinander weiter entfernt liegen, als die Flanken der Nut voneinander beanstandet sind, welche aber durch elastische Verformung so weit aneinander angenähert werden können, dass ihrThe cover has at least two pairs of opposite lateral surface sides, which, when the cover is elastically relaxed, are further apart from one another than the flanks of the groove are spaced apart from one another, but which can be brought so close to one another by elastic deformation that they
Abstand gleich oder kleiner dem Abstand zwischen den Flanken der Nut ist. Distance is equal to or smaller than the distance between the flanks of the groove.
Durch dieses erste Merkmal ist erreichbar, dass die Abdeckung in mindestens zwei voneinander verschiedenen Lagen, die durch Dre- hung um eine zur Längsrichtung der Abdeckung parallel liegende Achse uumm einen anderen Winkel als 180° ineinander überführbar sind, in die Nut einbringbar ist und in dieser zufolge Druck zu- folge elastischer Vorspannung hält. This first feature makes it possible for the cover to be inserted into the groove in at least two different positions, which can be moved into one another by rotation about an axis parallel to the longitudinal direction of the cover and at an angle other than 180° due to pressure due to elastic prestress.
Merkmal 2: Feature 2:
Jene Parameter der Abdeckung, welche die optisch wahrnehmbaren Eigenschaften des von der Lichtquelle stammenden und normal, zu deren Längsrichtung durch die Abdeckung hindurchtretenden Lich- tes beeinflussen, werden so eingestellt, dass sie davon abhängig sind, in welcher jeweils zur Längsrichtung der Abdeckung normal liegenden Richtung sie die Abdeckung durchfluten. Those parameters of the cover which determine the optically perceptible properties of the light coming from the light source and normal to the longitudinal direction of the light passing through the cover tes are adjusted so that they depend on the direction in which they flow through the cover, which is normal to the longitudinal direction of the cover.
In Kombination mit dem Merkmal 1 wird damit die Möglichkeit ge- boten zwischen unterschiedlichen optischen Wirkungen der Abde- ckung wählen zu können, indem die Abdeckung in einer von mehre- ren möglichen Lagen in der Nut positioniert wird. In combination with feature 1, this offers the possibility of being able to choose between different optical effects of the cover by positioning the cover in one of several possible positions in the groove.
Die langgestreckte transparente oder transluzente Abdeckung be- steht also aus einem elastomeren Material, wobei zumindest zweiThe elongated transparent or translucent cover therefore consists of an elastomeric material, with at least two
Außenabmessungen der Querschnittsfläche ssoo bemessen sind, dass sie dann, wenn die Abdeckung nicht elastisch verformt ist, grö- ßer sind als der Abstand der Flanken der Nut und dass sie aber durch elastische Verformung so weit verkleinerbar sind, dass sie kleiner sind als der Abstand zwischen den Flanken der Nut. External dimensions of the cross-sectional area ssoo are dimensioned so that they are larger than the distance between the flanks of the groove when the cover is not elastically deformed and that they can be reduced by elastic deformation to such an extent that they are smaller than the distance between the flanks of the groove.
Es wird damit erreicht, dass die Abdeckung in der Nut montiert werden kann, indem sie einfach in den Zwischenraum zwischen den beiden Flanken der Nutz hineingequetscht wird. Nach der Montage ist die Querschnittsfläche der Abdeckung gegenüber der elastisch entspannten Form derart elastisch verformt, dass die zur Rich- tung des Abstandes der beiden Nutflanken parallel liegende Quer- schnittsabmessung verringert ist. AAnn den Berührungsflächen zu den Nutflanken liegt die Abdeckung dann zufolge elastischer Vor- spannung unter Druck an und hält damit in der Nut kraftschlüs- sig. This ensures that the cover can be mounted in the groove by simply squeezing it into the space between the two flanks of the utility. After assembly, the cross-sectional area of the cover is elastically deformed relative to the elastically relaxed shape in such a way that the cross-sectional dimension lying parallel to the direction of the distance between the two groove flanks is reduced. At the contact surfaces with the groove flanks, the cover is then under pressure due to elastic pre-stress and thus holds in the groove in a force-fitting manner.
Typischerweise ist das elastomere Material, aus welchem die Ab- deckung im Wesentlichen besteht, Silikon. Damit ist es sehr ein- fach möglich die Querschnittsabmessungen der Abdeckung so zu be- messen, dass die Abdeckung einfach von Hand aus, ohne Erforder- nis irgendwelcher Werkzeuge, bestimmungsgemäß in die Nut einge- bracht werden kann, und dann sicher und stabil auf Jahrzehnte darinnen hält. Das für den Montagevorgang erforderliche elasti- sehe Komprimieren der Querschnittsfläche geht recht einfach, in- dem die Abdeckung in ihrer Längsrichtung von Hand aus gedehnt wird. Ein Mensch gewinnt die für das Montieren erforderliche Fingerfertigkeit innerhalb weniger Übungsminuten, sodass die weitere Montage mühelos rasch und genau erfolgen kann. Typically, the elastomeric material of which the cover essentially consists is silicone. This makes it very easy to measure the cross-sectional dimensions of the cover in such a way that the cover can simply be inserted into the groove as intended by hand, without the need for any tools, and then safely and stably for decades holds inside. The elastic required for the assembly process Compressing the cross-sectional area is quite easy by stretching the cover in its longitudinal direction by hand. A person gains the dexterity required for assembly within just a few minutes of practice, so that further assembly can be carried out quickly and accurately without any effort.
Fig. 2: zeigt in gleicher Ansicht wie Fig. 1 eine erfindungsge- mäße Beleuchtungseinrichtung, welche sich gegenüber jener von Fig. 1 nur durch die Lage der Abdeckung in der Nut un- terscheidet. Fig. 2: shows, in the same view as Fig. 1, a lighting device according to the invention, which differs from that of Fig. 1 only in the position of the cover in the groove.
Fig. 3: zeigt - mit übertrieben dargestellten besonderen Merk- malen - in Querschnittsansicht eine weitere mögliche Abde- ckung in elastisch entspanntem Zustand. Fig. 3: shows - with special features exaggerated - in a cross-sectional view another possible cover in an elastically relaxed state.
Die in Fig. 1 und Fig. 2 dargestellten Beleuchtungseinrichtungen umfassen jeweils einen eine Nut 1 aufweisenden Teil 2, eine Lichtquelle 3 und eine Abdeckung 4. The lighting devices shown in Fig. 1 and Fig. 2 each include a part 2 having a groove 1, a light source 3 and a cover 4.
Die Lichtquelle 3, welche typischerweise ein LED-Lichtband sein kann, ist tief in die Nut 1 eingelegt und ist dort verankert, beispielsweise durch eine leichte Verklebung. The light source 3, which can typically be an LED light strip, is inserted deep into the groove 1 and is anchored there, for example by light gluing.
Die Abdeckung 4 besteht aus einem transparenten oder transluzen- ten elastomeren Material und ist profilartig oder bandartig langgestreckt. Sie ist näher an der offenen Mantelflächenseite der Nut 1 in dieser angeordnet als die Lichtquelle 3, sodass sie eine Abdeckung der Lichtquelle 3 darstellt. Die Längsrichtung der Abdeckung 4 liegt parallel zur Längsrichtung der Nut 1, und sie hält in der Nut 1, indem sie elastisch etwas komprimiert ist und durch elastische Vorspannung zwischen den Flanken der Nut 1 eingeklemmt ist. In einem vorteilhaften und typischen Fall besteht die Abdeckung 4 aus transparentem Silikon, ist also im Wesentlichen ein Profil aus Silikon, welches etwa wie ein Band aufwickelbar ist. Silikon hat verglichen mit Konstruktionsmaterialien wie Holz oder Metal- len eine sehr weite elastische Verformbarkeit und einen sehr niedrigen Elastizitätsmodul. Zum Einbringen in die Nut 1 kann die Abdeckung 4 einfach per Hand in ihrer Längsrichtung gedehnt werden, sodass ihre Querschnittsabmessungen (die zur Längsrich- tung normal zu messenden Abmessungen) verringern und die Abmes- sung in die Nut 1 eindrückt oder eingelegt werden kann. Nach dem Loslassen der Abdeckung 4 bildet sich ihre elastische Dehnung zurück, und ihre Querschnittsabmessungen vergrößern sich, bis die Abdeckung 4 unter sattem elastischem Druck mit zwei einander gegenüberliegenden Mantelflächenseiten an den Flanken der Nut 1 anliegt und durch Reibung kraftschlüssig in der Nut hält. DieThe cover 4 consists of a transparent or translucent elastomeric material and is elongated like a profile or band. It is arranged closer to the open lateral surface side of the groove 1 than the light source 3, so that it represents a cover for the light source 3. The longitudinal direction of the cover 4 is parallel to the longitudinal direction of the groove 1, and it holds in the groove 1 by being somewhat elastically compressed and clamped between the flanks of the groove 1 by elastic prestress. In an advantageous and typical case, the cover 4 consists of transparent silicone, i.e. is essentially a profile made of silicone, which can be wound up like a band. Compared to construction materials such as wood or metals, silicone has a very wide elastic deformability and a very low modulus of elasticity. To insert it into the groove 1, the cover 4 can simply be stretched by hand in its longitudinal direction, so that its cross-sectional dimensions (the dimensions to be measured normally in the longitudinal direction) are reduced and the dimension can be pressed or inserted into the groove 1. After the cover 4 is released, its elastic expansion returns and its cross-sectional dimensions increase until the cover 4 rests against the flanks of the groove 1 under full elastic pressure with two opposite lateral surface sides and is held in the groove by friction. The
Abdeckung 4 schützt dann die Lichtquelle 3 in mehrerlei Hin- sicht, und sie bildet einen sauberen Verschluss der Nut 1. Cover 4 then protects the light source 3 in several respects, and it forms a clean closure of the groove 1.
Bevorzugt sind die beiden Flankenflächen der Nut 1 - wie darge- stellt - rreecchhttwwiinnkkeelliigg zzuu jener Oberfläche des Gegenstandes 2 ausgebildet, in welcher die Nut 1 verläuft. Die diesbezüglichePreferably, the two flank surfaces of the groove 1 - as shown - are designed to be parallel to that surface of the object 2 in which the groove 1 runs. The relevant one
Form der Querschnittsfläche der Nut ist besonders einfach durchThe shape of the cross-sectional area of the groove is particularly simple
Fräsen oder sogar durch Schneiden mittels eines Kreissägeblattes herstellbar, und die Abdeckung 4 hält zuverlässig in der gewähl- ten Tiefe der Nut 1. Milling or even cutting using a circular saw blade, and the cover 4 holds reliably in the selected depth of the groove 1.
Indem die Abdeckung 4 aauuss einem elastomeren Material besteht, ist sie nicht nur in ihrer Querschnittsfläche elastisch verform- bar, sondern auch wie ein Faden oder Band weich und zerstörungs- frei biegsam. Dadurch kann die Abdeckung 4 problemlos nicht nur in gerade verlaufende Längenbereiche der Nut 1 eingebracht wer- den, sondern auch in gekrümmt verlaufende Längenbereiche der NutBecause the cover 4 is made of an elastomeric material, it is not only elastically deformable in its cross-sectional area, but also soft and non-destructively flexible like a thread or ribbon. As a result, the cover 4 can be easily inserted not only into straight length regions of the groove 1, but also into curved length regions of the groove
1. Es führt daher zu keinerlei Schwierigkeiten, wenn die Nut 1 entlang der Oberfläche des Gegenstandes 2 beispielsweise kreis- ringförmig oder entlang irgendwelcher ornamentartiger Linienzüge verläuft. 1. It therefore does not lead to any difficulties if the groove 1 is circular along the surface of the object 2, for example in a ring or along any ornamental lines.
In den in Fig. 1 und Fig. 2 dargestellten Beispielen ist die Querschnittsflächenform der Abdeckung 4 in elastisch nicht ver- formtem Zustand eine quadratische Fläche. Dadurch kann die Abde- ckung 4 besonders gut definiert in mehreren unterschiedlichen Drehlagen, die zur jeweils nächsten Drehlage um jeweils 90 ° ver- dreht sind, in der Nut 1 angeordnet werden. In the examples shown in FIGS. 1 and 2, the cross-sectional surface shape of the cover 4 in the elastically undeformed state is a square surface. As a result, the cover 4 can be arranged in the groove 1 in a particularly well-defined manner in several different rotational positions, which are each rotated by 90° to the next rotational position.
Die Abdeckung 4 besteht in dem in Fig. 1 und Fig. 2 gezeigten Beispiel überwiegend aus transparentem Material, typischerweise Silikon, welches sichtbares Licht ohne wesentliche Streuung oder Ablenkung durchtreten lässt. Nur an zwei einander gegenüberlie- gende Mantelflächenseiten ist die Abdeckung 4 mit jeweils einer oberflächlichen Schicht 5 versehen, welche zwar auch transparent ist, durchgehendes Licht aber diffus streut, oder verfärbt. Eine derartige Schicht 5 kann beispielsweise aus transparentem Sili- kon und darin eingebetteten Fremdkörperpartikeln gebildet sein. In the example shown in FIGS. 1 and 2, the cover 4 consists predominantly of transparent material, typically silicone, which allows visible light to pass through without significant scattering or deflection. Only on two opposite lateral surface sides is the cover 4 provided with a superficial layer 5, which is also transparent, but diffusely scatters or discolors transmitted light. Such a layer 5 can be formed, for example, from transparent silicone and foreign body particles embedded therein.
Gemäß Fig. 11 ist die Abdeckung 4 ddeerraarrtt in die Nut 1 einge- bracht, dass die Schichten 5 die Breite der Nut 1 überbrücken, und Licht, welches durch die Lichtquelle 3 ausgesandt wird und durch die Abdeckung 4 durchdringt, zwangsweise die Schichten 5 durchflutet, und damit diffus gestreut oder verfärbt wird. Gemäß Fig. 2 hingegen ist die Abdeckung 4 derart in die Nut 1 einge- bracht, dass die Schichten 5 parallel zzuu den Flanken der Nut 1 liegen und damit die Nutbreite nicht überbrücken, sodass der überwiegende Teil jenes Lichtes, welches durch die Lichtquelle 3 ausgesandt wird und durch die Abdeckung 4 hindurch flutet, an den Schichten 5 vorbei flutet, und damit nicht diffus gestreut bzw. verfärbt wird. Jedoch kann in diesem Fall eine optische Verbesserung der an der Abdeckung 4 anliegenden Nutflanken er- reicht werden, da das Erscheinungsbild der Nutflanken diffus ge- streut oder verfärbt wird. Durch die Wahl des Winkels um ihre Längsachse in welchem die Ab- deckung 4 in der Nut 1 verankert wird, ist also einstellbar, ob die Beleuchtungseinrichtung stärker oder weniger stark diffus gestreutes Licht abgibt. 11, the cover 4 is inserted into the groove 1 so that the layers 5 bridge the width of the groove 1, and light, which is emitted by the light source 3 and penetrates through the cover 4, forcibly floods the layers 5 , and thus diffusely scattered or discolored. 2, however, the cover 4 is inserted into the groove 1 in such a way that the layers 5 lie parallel to the flanks of the groove 1 and thus do not bridge the groove width, so that the majority of the light that is emitted by the light source 3 is and floods through the cover 4, floods past the layers 5, and is therefore not diffusely scattered or discolored. However, in this case, an optical improvement of the groove flanks resting on the cover 4 can be achieved since the appearance of the groove flanks is diffusely scattered or discolored. By choosing the angle around its longitudinal axis at which the cover 4 is anchored in the groove 1, it is possible to set whether the lighting device emits more or less diffusely scattered light.
Zu den beispielhaften Darstellungen und der Erklärung dazu gibt es innerhalb des Erfindungsgedankens einige Verallgemeinerungen und Variationen. Ohne Anspruch auf Vollständigkeit seien mehrere davon kurz erwähnt: In addition to the exemplary representations and the explanation therefor, there are some generalizations and variations within the inventive concept. Without claiming to be complete, several of them should be briefly mentioned:
Die Querschnittsfläche der Abdeckung 4 kann auch anders als quadratisch sein. Im Prinzip gibt es dafür kaum andere Ein- Schränkungen als jene, dass die Abdeckung 4 in mindestens zwei verschiedenen Drehpositionen in der Nut 1 durch elastische Klem- mung fixierbar sein muss. Besonders vorteilhaft sind neben der quadratischen Querschnittsflächenformen wohl rechteckige Formen bei denen Länge und Breite nur wenig unterschiedlich sind, sowie ganz allgemein Querschnittsflächenformen deren Umfangslinie ein geschlossener Polygonzug ist, bei welchem mehrere Paare von je- weils zwei Teilstücken vorkommen, welche parallel zueinander ausgerichtet sind. Eine besonders vorteilhafte Querschnittsflä- chenform ist neben dem Quadrat wohl auch das regelmäßige Sechs- eck; es lässt die Wahl von drei Lagen zzuu,, die sich untereinander bezüglich der optischen Effekte unterscheiden können. The cross-sectional area of the cover 4 can also be other than square. In principle, there are hardly any restrictions other than the fact that the cover 4 must be able to be fixed in at least two different rotational positions in the groove 1 by elastic clamping. In addition to the square cross-sectional surface shapes, particularly advantageous are rectangular shapes in which the length and width differ only slightly, and more generally cross-sectional surface shapes whose circumferential line is a closed polygon, in which several pairs of two sections each occur, which are aligned parallel to one another. In addition to the square, a particularly advantageous cross-sectional surface shape is also the regular hexagon; It allows the choice of three layers, which can differ from each other in terms of optical effects.
Optische Eigenschaften die bei entsprechender Einstellung von Parametern der Abdeckung 4 als vom Einlegewinkel der Abdeckung 4 wählbar beinflussbar ausgebildet werden können, sind unter ande- rem: Streuung, Ausmaß der Transparenz, Farbe, Fokussierung,Optical properties that can be designed to be influenced by the insertion angle of the cover 4 when the parameters of the cover 4 are set accordingly include: scattering, extent of transparency, color, focusing,
Farbtemperatur (wärmeres oder kühleres Weiß) des durchflutenden Lichtes. Color temperature (warmer or cooler white) of the light flowing through.
Die Schichten 5 der Abdeckung 4, welche die optischen Eigen- schäften beeinflussen, können unter anderem gebildet werden durch Co-Extrusion mit dem Kernmaterial, Bearbeiten von Oberflä- chenbereichen (aufrauen, ätzen, thermisches behandeln, definiert strukturiert abtragen), Beschichten von Oberflächenbereichen, Verkleben mit Materialschichten. The layers 5 of the cover 4, which influence the optical properties, can be formed, among other things, by co-extrusion with the core material, processing of surfaces areas (roughening, etching, thermal treatment, removal in a defined structured manner), coating surface areas, bonding with layers of material.
Es können mehr als zwei gegenüberliegende Mantelflächenpaare der Abdeckung für die Anlage an den Nutflanken vorgesehen sein, und dementsprechend unterschiedliche optische Parameter aufweisen. Es ist auch möglich die beiden Mantelflächenseiten eines Paares von für das Halten in der Nut zusammenwirkenden Mantelflächen- selten der Abdeckung mit unterschiedlichen optisch wirksamen Pa- rametern auszubilden. More than two opposing pairs of lateral surfaces of the cover can be provided for contact with the groove flanks, and accordingly have different optical parameters. It is also possible to design the two lateral surface sides of a pair of lateral surfaces - rarely the cover - which cooperate for holding in the groove with different optically effective parameters.
Fig. 3 zeigt in gegenüber Fig. 1 und Fig. 2 vergrößertem Maßstab eine weitere mögliche erfindungsgemäße Abdeckung 6 in Quer- schnittsansicht. Die einen zwei einander gegenüberliegende Man- telflächenseiten sind konvex gewölbt, und die anderen zwei ei- nander gegenüberliegende Mantelflächenseiten ssiinndd konkav ge- wölbt. Je nach Einbaulage flutet das Licht durch die konvex oder durch die konkav gewölbten Mantelflächenseiten der Abdeckung 6 hindurch, womit die Abdeckung auf das durchflutende Licht (in einer Dimension) entweder nach Art einer Sammellinse oder nach3 shows, on an enlarged scale compared to FIGS. 1 and 2, a further possible cover 6 according to the invention in a cross-sectional view. The one two opposing lateral surface sides are convexly curved, and the other two opposing lateral surface sides are concavely curved. Depending on the installation position, the light floods through the convex or concave lateral surface sides of the cover 6, which means that the cover responds to the flooding light (in one dimension) either in the manner of a converging lens or after
Art einer Zerstreuungslinse wirkt. Kind of a diverging lens works.
Da die Wölbung der in Einbausituation nicht an den Flankenflä- chen der Nut anliegenden Mantelflächenseiten gegenüber dem dar- gestellten elastisch entspannten Zustand stark vergrößert ist, ist es bei der tatsächlichen Ausführung einer Abdeckung gemäß dem in Fig. 3 gezeigten Prinzip ratsam die Krümmung der Mantel- flächenseiten in elastisch entspanntem Zustand deutlich geringer als in Fig. 3 dargestellt auszubilden. Since the curvature of the lateral surface sides that do not rest on the flank surfaces of the groove in the installation situation is greatly increased compared to the elastically relaxed state shown, when actually designing a cover according to the principle shown in FIG. 3, it is advisable to curvature the lateral surface. The surface sides in the elastically relaxed state should be significantly smaller than those shown in FIG.
