Description

Die Erfindung betrifft eine Vorrichtung mit lichtemittierenden Dioden für die Markierung von Flächen, vorzugsweise wichtigen öffentlichen Bereichen, wie das beispielsweise bei Markierungen auf Strassen und Autobahnen, auf Flugplätzen, in Schwimmbädern, auf Fassaden und dergleichen erwünscht und/oder notwendig ist.The invention relates to a device with light-emitting diodes for the marking of areas, preferably important public areas, as desired and / or necessary for example in markings on roads and highways, on airfields, in swimming pools, on facades and the like.

Besteht das Bedürfnis, erleuchtbare Markierungen in Bauwerksteile mit geringem kostenseitigen Aufwand und grösserer Helligkeit zu integrieren, werden sehr häufig fertige Leuchten mit integrierten lichtemittierenden Dioden eingebaut, wie sie beispielsweise in der Internetpräsentation einer Firma We-ef enthalten sind und beispielhaft unter der Typenbezeichnung ETR 159 angeboten werden. Diese Leuchten bestehen aus einem wasserdichten, im wesentlichen rechteckigen oder runden Gehäuse, das je nach Abmessungen zusätzliche bauseitige Aufwendungen bis hin zu Gründungsmassnahmen erfordert. Die Ausführung derartiger Leuchten ist endlich und bei grösseren Längen erleuchteter Markierungen ist eine hinreichende Vielzahl von Leuchten entsprechend dem gewünschten Verlauf derartiger Markierungen auszubilden. Bei Reparaturen oder gar Zerstörungen ist die Leuchte unter Umständen komplett zu wechseln. Die Aufwendungen für die Installation derartiger Leuchten sind erheblich.If there is a need to integrate illuminable markings in building parts with low cost outlay and greater brightness, very often finished luminaires with integrated light-emitting diodes are incorporated, as are for example included in the Internet presentation of a company We-ef and offered by way of example under the type designation ETR 159 become. These luminaires consist of a watertight, essentially rectangular or round housing which, depending on the dimensions, requires additional on-site expenditures up to foundation measures. The execution of such lights is finite and with longer lengths of illuminated markers is a sufficient variety of lights according to the desired course of such markers form. In the case of repairs or even destruction, the luminaire may need to be completely replaced. The expenses for the installation of such lights are significant.

Als Bodenmarkierung wurde bereits vorgeschlagen, ziegelförmige Bausteine aus Kunststoff auszuführen, die zum Zweck einer elektrischen Installation hohl ausgeführt sind und bei denen eine Seitenfläche lichtdurchlässig und demontagefähig ausgebildet ist. Als Beleuchtung werden herkömmliche Leuchtmittel mit üblicher Netzspannung betrieben eingesetzt.As a floor marking has already been proposed to perform brick-shaped blocks made of plastic, which are designed to be hollow for the purpose of electrical installation and in which a side surface translucent and disassembled is trained. As lighting conventional bulbs operated with usual mains voltage are used.

Hierbei handelt es sich um Baueinheiten, die für geringere beleuchtungstechnische Ansprüche und vorzugsweise im Hausgebrauch nachrüstbar sind. Problematisch ist der Schutz gegen eindringende Nässe.These are building units that can be retrofitted for lower lighting requirements and preferably in domestic use. The problem is the protection against penetrating moisture.

Nach einer Firmenschrift der Fa. Kiss, D 58455 Witten, wird vorgeschlagen, zu Markierungszwecken lichtdurchlässige, aus Kunststoff gefertigte Bausteine, in die lichtmettierende Dioden eingegossen sind, in Bauwerksflächen einzulegen, wobei die Dimension der Bausteine dem umgebenden Sortiment angepasst ist und bei einem Defekt des Systems der Baustein gewechselt werden muss.According to a company publication of the company Kiss, D 58455 Witten, it is proposed for marking purposes translucent, made of plastic components, are cast in the light-emitting diodes in building areas, the dimension of the blocks is adapted to the surrounding range and a defect of Systems of the block must be changed.

Bei allen bisher benannten Bauweisen bedingt die vorhandene Ausgestaltung der Leuchteneinheit die Anpassung der Bauausführung und bei grösseren Ausführungslängen eine Multiplizierung des Aufwandes für den Einbau einer Leuchte.In all previously named constructions, the existing design of the lighting unit requires the adaptation of the construction and, for larger execution lengths, a multiplication of the effort for the installation of a lamp.

Nach der DE-OS 10 2004 005 371 A1 wird deshalb vorgeschlagen, einen Bahnsteig so auszurüsten, dass in die Betonfertigteile, aus denen der Bahnsteig besteht, Aussparungen eingebracht sind oder vor Ort eingebracht werden. In diese Aussparungen werden handelsübliche Leuchten, bei denen als Leuchtmittel LEDs verwendet sind, oder Leuchtdiodenbänder in U-förmige aus Kunststoff gefertigte Wannen eingebracht und diese eingeklebt und anderweitig ortsfest verlegt. Die Leuchteneinheiten sind in ihrer Baulänge an den Abmessungen der Betonteile orientiert und zur Erreichung grösserer Längen durch Verbindungselemente untereinander gekoppelt. Das kann ebenfalls eine Vielzahl von Punktleuchten sein. Eine Abdeckung erfolgt durch nicht näher beschriebene und verklebte Laufplatten.After DE-OS 10 2004 005 371 A1 It is therefore proposed to equip a platform so that in the precast concrete parts that make up the platform, recesses are introduced or introduced on site. In these recesses are commercially available lights, which are used as bulbs LEDs, or LED strips in U-shaped plastic-made trays introduced and glued and otherwise laid stationary. The luminaire units are oriented in their length to the dimensions of the concrete parts and coupled to achieve greater lengths by connecting elements with each other. This can also be a variety of point lights. A cover is made by unspecified and glued Laufplatten.

In der Schrift WO 03/024188 A2 sind lichtemittierende Dioden in einem Kanalteil fest installiert. Während eine Seite des Kanalteiles notwendige Steuer- und Kontrolleinheiten und dergleichen aufnimmt, ist das andere als Endverschluss ausgebildet oder weist Steckkontakte dergestalt auf, dass es mit einem weiteren Bauteil gleicher Art zum Zweck der Verlängerung koppelbar ist. Die lichtemittierenden Dioden sind von einem lichtdurchlässigen Material bedeckt, das Schutz vor der Witterung und anderen schädigenden physikalischen Einflüssen bietet.In Scripture WO 03/024188 A2 Light emitting diodes are permanently installed in a duct part. While one side of the channel part receives necessary control and monitoring units and the like, the other is designed as an end closure or has plug contacts in such a way that it can be coupled with another component of the same type for the purpose of extension. The light-emitting diodes are covered by a translucent material that provides protection from weathering and other damaging physical influences.

Gemäss der Schrift 202 09 472 U1 sind in ein Profilrohr Leuchteinheiten eingeschoben. Das Profilrohr ist im oberen Bereich lichtdurchlässig ausgeführt.According to the publication 202 09 472 U1 light units are inserted into a profile tube. The profile tube is designed to be translucent in the upper area.

Beide Einrichtungen weisen seitlich oder nach unten gerichtete Verankerungen auf.Both devices have laterally or downwardly directed anchorages.

Aufgabe der Erfindung ist es deshalb, einen Leuchtenaufbau unter Verwendung von lichtemittierenden Dioden zu schaffen, der zum einen reparaturfreundlich ist und bei dem eine Anpassung der Leuchteneinheit an die Einbauverhältnisse gegeben ist, sodass sich neue Einsatzmöglichkeiten durch einfache Veränderung der Form und/oder einer nahezu unendlichen Ausführungslänge für derartige Leuchten ergeben.The object of the invention is therefore to provide a light assembly using light-emitting diodes, which is repair-friendly and in which an adaptation of the lamp unit is given to the installation conditions, so that new applications by simply changing the shape and / or an almost infinite Execution lead length for such lights.

Die Aufgabe wird gelöst durch eine Vorrichtung gemäss Patentanspruch 1, wobei auf die Lichtaustrittsfläche eine Verschleissschutzschicht aufgebracht werden kann.The object is achieved by a device according to claim 1, wherein a wear protection layer can be applied to the light exit surface.

Als Kunststoffprofil wird vorzugsweise Polyäthylenschlauch verwendet, der lichtdurchlässig ausgeführt ist und der ebenso vorzugsweise eine Verstärkungseinlage zur Erhöhung seiner statischen Stabilität aufweisen kann. Das ist üblicherweise eine spiralartig ausgeführte und in die Wandung integrierte Stahleinlage.As a plastic profile preferably polyethylene tube is used, which is made translucent and may also preferably have a reinforcing insert to increase its static stability. This is usually a spiral-shaped and integrated into the wall steel insert.

Das verwendete lichtdurchlässige Kunststoffprofil ist regelmässig klar lichtdurchlässig ausgeführt, kann aber ebenso in Fällen, wo eine bestimmte Lichtfarbe vorbestimmt ist, bereits eingefärbt sein.The translucent plastic profile used is regularly made clear translucent, but may also be colored in cases where a specific light color is predetermined.

Die vorgesehene reflektierende Beschichtung mit der Wirkung eines Hohlspiegels kann auf der dem vorgesehenen Lichtaustritt gegenüberliegenden unteren Aussenseite oder der unteren Innenseite angebracht sein. Dabei kann es sich beispielhaft um eine reflektierende Folie oder eine hochglänzende Aluminiumschale handeln. Es kann aber ebenso ein Anstrich verwendet sein, der nach seinem Trocknen reflektierende Eigenschaften aufweist.The proposed reflective coating with the effect of a concave mirror can be mounted on the lower outer side or the lower inner side opposite the intended light exit. This may be, for example, a reflective foil or a high-gloss aluminum shell. But it can also be used as a paint, which has reflective properties after drying.

Eine weitere vorgeschlagene Variation sieht vor, den statisch stabilen lichtdurchlässigen Körper aus einem ausgehärteten, im Verarbeitungszustand giessfähigen Polyesterharz bestehend auszuführen. Der Vorteil besteht darin, dass bei eingefrästen Aussparungen in die zu verändernden Bauwerksteile alle Toleranzen ausgeglichen werden und ein Verkleben mit diesen gegeben ist.A further proposed variation provides to carry out the statically stable translucent body consisting of a cured polyester resin pourable in the processing state. The advantage is that when milled recesses in the parts of the building to be changed all tolerances are compensated and gluing is given with these.

Werden vorbestimmte Aussparungen oder solche Aussparungen, die sich Bodenunebenheiten anpassen müssen oder die sich gar in Fassaden befinden, ausgerüstet, kann es vorteilhaft sein, den statisch stabilen lichtdurchlässigen Körper aus einem vorgefertigten flexiblen Kunststoff bestehend auszuführen. Dabei handelt es sich in den meisten Fällen um einen flexibel eingestellten Kunststoff auf PUR-Basis.If predetermined recesses or recesses which have to adapt to unevenness in the floor or are even located in facades are equipped, it may be advantageous to carry out the statically stable translucent body consisting of a prefabricated flexible plastic. These are in most cases a flexibly adjusted plastic based on PUR.

Wird ein vorgefertigter statisch stabiler mindestens zur Lichtaustrittsseite hin lichtdurchlässiger Körper verwendet, kann dieser ebenfalls in seiner Längsrichtung verlaufend und quer zu seiner Breite mehrteilig ausgeführt sein. Wird hierbei eine Ober- und eine getrennte Unterschale verwendet, kann die Unterschale ebenfalls aus einem untergeordnetem Material, beispielsweise aus Ortbeton, gefertigt worden sein.If a prefabricated, statically stable body which is translucent at least to the light exit side is used, this body can likewise be embodied in several parts running in its longitudinal direction and transversely to its width. If an upper and a separate lower shell are used, the lower shell can also be used be made of a subordinate material, such as in-situ concrete.

Damit sich die Diodenplatinen im Kunststoffprofil nicht verdrehen können und die lichtabgebende Seite stets zur Lichtaustrittsseite hin zeigt, können diese fixiert sein. Die Erfindung sieht zur Verwirklichung dieser Zielstellung vor, dass das Kunststoffprofil deshalb in Längsrichtung verlaufend auf seiner Innenseite Nuten aufweist, zwischen die die Diodenplatinen eingeschoben werden. Es ist ebenso möglich, ein auf einer Spitze fixiertes quadratisches Kunststoffprofil einzusetzen und die Diodenplatinen masslich so auszuführen, dass diese in ihrer Breite nahezu dem inneren Diagonalmass entsprechend ausgeführt sind. Damit wird ebenso ein Verdrehen der Diodenplatinen im Kunststoffprofil verhindert.Thus, the diode boards can not rotate in the plastic profile and the light-emitting side always points to the light exit side, they can be fixed. To achieve this objective, the invention provides that the plastic profile therefore has grooves extending in the longitudinal direction on its inner side, between which slots the diode boards are inserted. It is also possible to use a fixed on a tip square plastic profile and dimensionally execute the diode boards so that they are designed in width almost equal to the inner Diagonalmass. This also prevents twisting of the diode boards in the plastic profile.

Eine Abnutzung auf der Lichtaustrittsseite des mindestens zur Lichtaustrittsseite hin lichtdurchlässigen Körpers könnte statische Probleme verursachen. Ebenso würden sich Kratzer zu Lasten der Beleuchtungsstärke auswirken. Die Erfindung sieht deshalb vor, dass die Lichtaustrittsseite des lichtdurchlässigen Körpers eine Verschleissschutzschicht trägt. Diese besteht vorzugsweise aus einem Gemisch von Glaskugeln und einem, beispielsweise mittels eines Heissluftgebläses, aufschmelzbaren Kohlenwasserstoff-Harz. Damit wird die Oberfläche des lichtdurchlässigen Körpers festigkeitsmässig stabilisiert, ohne dass eine Beeinträchtigung der Lichtstärke eintritt. Es ist ebenso möglich, der Grundmischung vor deren Verarbeitung weitere die Rauhigkeit erhöhende Streuelemente zuzumischen, damit beispielsweise bei starkem Personenverkehr für diesen eine Gefährdung durch Rutschgefahr nicht gegeben ist.Wear on the light exit side of at least the light exit side translucent body could cause static problems. Similarly, scratches would be detrimental to illuminance. The invention therefore provides that the light exit side of the light-transmissive body carries a wear protection layer. This preferably consists of a mixture of glass beads and a, for example by means of a hot air blower, fusible hydrocarbon resin. Thus, the surface of the translucent body is stabilized strength, without affecting the light intensity occurs. It is also possible to mix in the base mixture before processing further roughness-increasing scattering elements, so that, for example, in heavy passenger traffic for this hazard due to slipping is not given.

Die Glaskugeln werden vorzugsweise in Durchmesserbereichen zwischen 1 und 2,5 mm Durchmesser eingesetzt, wobei sich eine Mischung von 8 Teilen Glaskugeln sowie 2 Teilen Harz als zweckmässig erwiesen hat.The glass beads are preferably used in diameter ranges between 1 and 2.5 mm in diameter, with a mixture of 8 parts of glass beads and 2 parts of resin has proven to be expedient.

Es ist des weiteren möglich, die Diodenplatinen so auszuführen, dass diese mit farbig unterschiedlichen einzeln ansteuerbaren Dioden ausgeführt sind. Ebenso können solche Varianten zweckmässig sein, bei denen die Dioden einer Diodenplatine in einer Farbe und die Diodenplatinen farbig unterschiedlich ansteuerbar sortiert eingebaut sind.It is also possible to design the diode boards in such a way that they are designed with differently colored, individually controllable diodes. Likewise, such variants may be expedient in which the diodes of a diode board in a color and the diode boards are mounted differently colored controllable assorted.

Da der Stromverbrauch durch die verwendeten Dioden gering ist, bietet es sich an, ebenso fernab einer durch Kabel möglichen hinreichenden autarken Stromzuführung die Vorrichtung stromversorgungsseitig mit einer Speichereinheit zu verbinden, die mindestens zeitweilig von photovoltaischen Elementen gespeist ausgeführt ist.Since the power consumption by the diodes used is low, it makes sense, as far away from a possible cable by sufficient self-sufficient power supply to connect the device power supply side with a memory unit that is running at least temporarily powered by photovoltaic elements.

Es ist zweckmässig, wenigstens die mit Lichtaustritt versehenen Elemente UV-resistent auszuführen.It is expedient to perform at least the light-emitting elements UV-resistant.

Mit Hilfe der erfindungsgemässen Lösung ist es möglich, in allen Flächen, vorzugsweise Bauwerksflächen hinreichender Festigkeit nachträglich nach Einbringen entsprechender Aussparungen Beleuchtungseinrichtungen mit hohem energetischem Wirkungsgrad zu integrieren. Dabei ist es unerheblich, ob die Aussparungen nachträglich, beispielsweise durch Trennschleifen oder Ausfräsen, oder von vornherein eingebracht sind. Die erfindungsgemässe Vorrichtung kann bezogen auf ihre Längsausdehnung im wesentlichen planparallel und nahezu unendlich ausgeführt sein, also in Form eines gleichmässig breiten unendlichen Lichtbandes. Es ist ebenso möglich, beispielsweise in eine Strasse, andere Formen einer beleuchteten Markierung, beispielsweise in Form eines Pfeiles, einzubringen, ohne dass die Notwendigkeit zu grundsätzlichen technologischen Veränderungen besteht. Ebenso ist das Einbringen einer derartigen Vorrichtung beispielsweise in einem Schwimmbecken über dessen gesamte Breite möglich, indem die erfindungsgemässe Vorrichtung in eine Nut im Boden eingelassen ist und das für die Dioden notwendige Vorschaltgerät ausserhalb des Beckens angeordnet ist. Abgesehen davon, dass ein Wechsel der Farbe des erzeugten Lichtes ohne weiteres möglich ist, ist die erfindungsgemässe Vorrichtung gleichermassen für die Ausrüstung von Flugplätzen, Bahnhöfen, Verkehrshöfen und dergleichen öffentlichen Bauten bedeutsam, weil sie nicht nur wasserdicht, sondern ebenso befahr- und begehbar ist. Durch das Einschieben der miteinander verbundenen Diodenplatinen in ein Kunststoffprofil ist in den meisten Fällen einer Längsausdehnung ebenfalls die Reparatur einer Diodenplatine, wenn erforderlich, bei Verringerung bisher bekannter Aufwendungen möglich. Das Verwenden von im Verarbeitungszustand giessfähigen Kunststoffen führt dazu, dass eine innige Bindung beispielsweise zum umgebenden Asphalt entsteht. Das nachträgliche Aufbringen einer Verschleissschutzschicht, wie erwähnt, führt zum Versiegeln der Oberfläche. Ist eine hinreichende Überdeckung des Kunststoffprofils gegeben, ist selbst schwerer Fahrverkehr ohne Beeinträchtigung der Anordnung möglich. Das Aufbringen einer insbesondere aus Glaskugeln bestehenden Verschleissschutzschicht hat sich ebenfalls als beleuchtungstechnisch vorteilhaft erwiesen. Ebenso kann durch den erfindungsgemässen Aufbau der vorgeschlagenen Vorrichtung bei einem Untergrund mit unterschiedlichem Höhenniveau reagiert werden, ohne dass sich negative Auswirkungen für die Ausbildung und/oder die Funktion ergeben.With the aid of the inventive solution, it is possible in all areas, preferably building areas of sufficient strength subsequently to integrate after the introduction of corresponding recesses lighting devices with high energy efficiency. It is irrelevant whether the recesses are subsequently introduced, for example by cutting or milling, or from the outset. With regard to its longitudinal extension, the device according to the invention can be designed substantially plane-parallel and almost infinitely, that is to say in the form of a uniformly wide, infinite light band. It is also possible, for example in a street, to introduce other forms of illuminated marking, for example in the form of an arrow, without the need for fundamental technological changes. Likewise, the introduction of such a device, for example, in a swimming pool over its entire width is possible by the Inventive device is embedded in a groove in the ground and the ballast necessary for the diodes is arranged outside the basin. Apart from the fact that a change in the color of the light generated is readily possible, the device according to the invention is equally important for the equipment of airfields, railway stations, public roads and the like public buildings because it is not only waterproof, but also passable and accessible. By inserting the interconnected diode boards in a plastic profile in most cases a longitudinal extent is also the repair of a diode board, if necessary, possible in reducing previously known expenses. The use of plastics which can be cast in the processing state results in intimate bonding, for example with respect to the surrounding asphalt. The subsequent application of a wear protection layer, as mentioned, leads to the sealing of the surface. If there is sufficient coverage of the plastic profile, even heavy traffic is possible without affecting the arrangement. The application of an existing in particular of glass beads wear protection layer has also proved to be advantageous in terms of lighting technology. Likewise, by the inventive structure of the proposed device can be reacted to a background with different height level, without resulting in negative effects on the training and / or the function.

Die Erfindung soll nachstehend an zwei Ausführungsbeispielen näher erläutert werden.The invention will be explained in more detail below with reference to two embodiments.

I.I.

Aufgabe war es, in die Oberfläche der Zuwegung zu einem stark befahrenen Hotelparkplatz einen erleuchteten Pfeil von 1 m Länge und über die Enden der Pfeilung gemessen von 0,4 m Breite zu integrieren, damit insbesondere den Hotelgästen, die erstmalig das Hotel mit ihrem Fahrzeug besuchen, der zutreffende Weg zum Abstellen ihres Fahrzeuges richtig gewiesen wird.Task was to integrate into the surface of the access to a busy hotel parking lot an illuminated arrow of 1 m in length and over the ends of the sweep measured by 0.4 m width, so that in particular the hotel guests, the first time the hotel with their vehicle visit the correct way to park your vehicle is proven.

Zu diesem Zweck werden mit einer Diamanttrennscheibe die Umrisse des gewünschten Pfeiles in die vorhandene asphaltierte Strasse als Fläche 1 geschnitten. Der Innenteil wird auf eine Tiefe von 10 cm ausgehoben.For this purpose, the outlines of the desired arrow in the existing paved road as a surface 1 are cut with a diamond blade. The inner part is dug to a depth of 10 cm.

Anschliessend wird das mit Diodenplatinen 2 besetzte und sie verbindende Stromzuführungskabel 3 in ein als glasklarer Polyäthylenschlauch ausgeführtes zur Lichtaustrittsfläche hin durchlässiges Kunststoffprofil 4 hineingezogen. Das Kunststoffprofil 4 weist als Verstärkungseinlage eine spiralförmige Armierung auf, besitzt mittig auf seiner Innenseite Nuten 8 zur horizontalen Sicherung der Diodenplatinen 2 und weist ein als reflektierende Beschichtung auf die vorgesehene Unterseite des Kunststoffprofils 4 aufgebrachtes hochglänzendes Aluminiumband auf. Im weiteren wird es mittig in der in der Bauwerksfläche 1 hergestellten Aussparung arretiert. Dieses Arretieren kann über kleine Kunststoffbeilagen erfolgen.Subsequently, the power supply cable 3, which is occupied by diode boards 2 and connects them, is drawn into a plastic profile 4 which is transparent to the light exit surface and is designed as a glass-clear polyethylene hose. The plastic profile 4 has as a reinforcing insert on a spiral reinforcement, has centrally on its inside grooves 8 for horizontal securing of the diode boards 2 and has a high-gloss aluminum tape applied as a reflective coating on the intended bottom of the plastic profile 4. In addition, it is locked in the middle in the recess made in the building surface 1. This locking can be done on small plastic inserts.

Nach Herstellen des elektrischen Anschlusses für die Diodenplatinen 2 wird die Aussparung in der Bauwerksfläche 1 mittels eines als lichtdurchlässiger Körper 6 wirkenden aushärtbaren giessfähigen Polyesterharzes bis etwa 5 mm unter das Niveau des Strassenbelages reichend vergossen. Nach Erreichen einer hinreichenden Stabilität der Oberfläche wird auf diese mittels eines Heissluftgebläses als Verschleissschutzschicht 7 eine Schicht eines Gemisches aus Glaskugeln mit 2 mm Durchmesser und eines aufschmelzbaren Kohlenwasserstoffharzes aufgebracht, dem Niveau der Zuwegung angeglichen und die Oberfläche geglättet.After making the electrical connection for the diode boards 2, the recess in the building surface 1 by means of acting as a translucent body 6 curable castable polyester resin to about 5 mm below the Pouring the level of the road surface. After reaching a sufficient stability of the surface is applied to this by means of a hot air blower as a wear protection layer 7, a layer of a mixture of glass beads with 2 mm diameter and a fusible hydrocarbon resin, adjusted the level of access and smoothed the surface.

Nach Eintreten der endgültigen Stabilität des aushärtbaren giessfähigen Polyesterharzes einschliesslich der Verschleissschutzschicht ist die hergestellte Orientierungseinrichtung gebrauchsfertig.After the final stability of the curable moldable polyester resin, including the wear protection layer, the orientation device produced is ready for use.

II.II.

Es ist vorgesehen, als Leiteinrichtung in einer Garagenzufahrt ein Lichtband in die Zuwegung zu integrieren. Deshalb wird ein möglichst gleichmässiger Kanal von 10 cm Breite in die als Fläche 1 dienende Zuwegung eingebracht..It is intended to integrate as a guide in a garage entrance a light strip in the Zuwegung. For this reason, a channel of 10 cm width, which is as even as possible, is inserted in the area serving as area 1.

Im weiteren wird eine Einlage vorbereitet, die aus Diodenplatinen 2, Stromzuführungskabel 3, einem als reflektierende Beschichtung 5 wirkenden Folienband sowie als zur Lichtaustrittsfläche hin lichtdurchlässigem Kunststoffprofil 4 dienendes klares Vierkantprofil vorbereitet. Die Breite der Diodenplatinen 2 ist geringfügig kleiner als die Länge der inneren Diagonale des Vierkantprofils. Auf den Grund der Aussparung und deren gesamte Länge wird eine Schicht eines fliessfähigen Betons 9 eingebracht und die Einlage so eingedrückt, dass sich die Kante des Vierkantprofils, die der vorgesehenen Lichtaustrittsfläche gegenüber liegt, im Beton 9 befindet. Die Lichtaustrittsfläche zeigt dabei nach oben. Es wurde weiterhin darauf geachtet, dass der Beton 9 höhenmässig bis zur Mitte der Einlage reicht. Im weiteren wird als lichtdurchlässiger Körper 6 ein flexibles klares Kunststoffprofil aufgelegt, das auf seiner Unterseite eine auf die äussere Gestaltung abgestimmte Aussparung aufweist.In addition, an insert is prepared prepared from diode boards 2, power supply cable 3, acting as a reflective coating 5 foil strip and as the light exit surface translucent plastic profile 4 serving clear square profile. The width of the diode boards 2 is slightly smaller than the length of the inner diagonal of the square profile. At the bottom of the recess and the entire length of a layer of a flowable concrete 9 is introduced and the insert is pressed so that the edge of the square profile, which is the intended light exit surface is located in the concrete 9. The light exit surface points upwards. Care was also taken to ensure that the concrete 9 extends in height to the middle of the insert. Furthermore, a translucent flexible body 6 is placed on a flexible clear plastic profile, which has on its underside a matched to the outer design recess.
