Abstract
(DE)
Lichtleitermatte (1) für die Herstellung eines block- oder quaderförmigen Lichtleitkörpers (21), die in einer Gussform angeordnet und mit einer gießfähigen, aushärtbaren Gießmasse (24) ausgießbar ist, wobei die Lichtleitermatte (1) aus gitterartig miteinander verbundenen Längs- und Querstegen (2, 3) besteht, die mindestens teilweise aus einem lichtleitenden Kunststoff bestehen, wobei im Kreuzungspunkt der Längs- und Querstege (2, 3) profilierte Lichtleitelemente (4) aus einem mindestens teilweise lichtleitenden Kunststoff angeformt sind, deren eine Stirnseite (6) als lichtabgebende Flächen an der Oberseite (22) des Lichtleitkörpers (21) ausgebildet sind, wobei mindestens die Längsstege (2) der Lichtleitermatte (1) als Lichtkanäle (5) zur Aufnahme von punktförmigen, lichterzeugenden Elementen ausgebildet sind, und dass die Lichtkanäle (5) an der bodennahen Seite der Lichtleitelemente (4) angeformt sind.
(EN)
Disclosed is a light guide mat (1) for the production of a block- or cuboid-shaped light guide body (21), which mat is arranged in a casting mould and can be sealed in a pourable, curable casting compound (24), wherein the light guide mat (1) consists of longitudinal and transverse struts (2, 3) connected to one another in the form of a grid, which struts consist at least partially of a light-conducting plastic, wherein profiled light guide elements (4) consisting of an at least partially light-conducting plastic are integrally formed at the point of intersection of the longitudinal and transverse struts (2, 3), an end face (6) of which elements being formed as light-emitting surfaces on the upper face (22) of the light guide body (21), wherein at least the longitudinal struts (2) of the light guide mat (1) are formed as light channels (5) for receiving point-like, light-generating elements, and the light channels (5) are integrally formed on the face of the light guide elements (4) near to the bottom.
(FR)
L'invention concerne un tapis guidant la lumière (1) destiné à la fabrication d'un corps guidant la lumière (21) ayant la forme d'un bloc ou d'un parallélépipède. Ledit tapis (1) est disposé dans un moule et peut être moulé avec une masse de moulage (24) moulable et durcissable. Le tapis guidant la lumière (1) est composé de barres longitudinales et transversales (2, 3), reliées entre elles pour former une sorte de grille, qui sont composées au moins en partie d'une matière synthétique guidant la lumière, des éléments guidant la lumière (4) profilés dans le point de croisement des barres longitudinales et transversales (2, 3) étant formés à partir d'une matière synthétique guidant au moins en partie la lumière, un côté frontal (6) desdits éléments (4) est conçu en tant que surface émettrice de lumière sur la face supérieure (22) du corps guidant la lumière (21), au moins les barres longitudinales (2) du tapis guidant la lumière (1) sont formées en tant que canaux lumineux (5) pour recevoir des éléments générateurs de lumière de forme ponctuelle et les canaux lumineux (5) sont formés sur la face proche du fond des éléments lumineux (4).
