Abstract
(DE)
Die Erfindung betrifft eine Flächenleuchte (100) mit zumindest einer Lichtquelle (110) zur Erzeugung zumindest eines gebündelten Lichtstrahls (S) und zumindest einem für den Lichtstrahl (S) transluzenten, scheibenförmigen Leuchtkörper (120) mit einer Vorderfläche(121) zum Austritt von Licht aus dem Leuchtkörper (120), einer der Vorderfläche (121) gegenüberliegenden Rückfläche (122) und einer Anzahl von die Vorderfläche (121) mit der Rückfläche (122) verbindenden Seitenflächen (123). Die zumindest eine Lichtquelle (110) ist zur Einkopplung des zumindest einen Lichtstrahls (S) durch zumindest einen als Eintrittsfläche (131) ausgebildeten Teilabschnitt zumindest einer der Seitenflächen (123) in den Leuchtkörper (120) angeordnet. Der Leuchtkörper (120) besteht aus einem Mischmaterial mit einer Vielzahl von Streuzentren (141) zur elastischen Streuung des zumindest einen Lichtstrahls (S) in einem für den zumindest einen Lichtstrahl (S) transparenten Grundmaterial (142). Jede der Seitenflächen (123) umfasst zumindest eine Reflektionsschicht (132) zur Reflektion des Lichtstrahls (S) in den Leuchtkörper (120). Die zumindest eine Eintrittsfläche (131) umfasst eine Aussparung in der zumindest einen Reflektionsschicht (132). Die Erfindung betrifft außerdem ein Verfahren zur Herstellung der Flächenleuchte (100).
(EN)
The invention relates to a surface light (100) comprising at least one light source (110) for generating at least one focused light beam (S) and at least one panel-like lighting body (120) which is translucent to the light beam (S) and has a front face (121) for light to emanate from the lighting body (120), a rear face (122) opposite the front face (121) and a plurality of lateral faces (123) connecting the front face (121) to the rear face (122). The at least one light source (110) is arranged for coupling the at least one light beam (S) into the lighting body (120) through at least one portion of at least one of the lateral faces (123) that is designed as an entry surface (131). The lighting body (120) consists of a mixed material having a plurality of scattering centres (141) for elastic scattering of the at least one light beam (S) in a base material (142) which is transparent to the at least one light beam (S). Each of the lateral faces (123) comprises at least one reflective layer (132) for reflecting the light beam (S) into the lighting body (120). The at least one entry surface (131) comprises a recess in the at least one reflective layer (132). The invention further relates to a method for producing the surface light (100).

La présente invention concerne un appareil d’éclairage plan (100) pourvu de : au moins une source de lumière (110) pour générer au moins un rayon lumineux (S) en faisceau ; et d’au moins un corps d’éclairage (120) en forme de vitre, translucide pour le rayon lumineux (S) pourvu d’une surface avant (121) pour l’émission de lumière depuis le corps d’éclairage (120), d’une surface arrière (122) opposée à la surface avant (121) et d’un certain nombre de surfaces latérales (123) reliant la surface avant (121) à la surface arrière (122). La ou les sources de lumière (110) sont disposées dans le corps d’éclairage (120) pour coupler le ou les rayons lumineux (S) par au moins un sous-secteur, conçu en tant que surface d’entrée (131), d’au moins une des surfaces latérales (123). Le corps d’éclairage (120) se compose d’un matériau composite pourvu d'une multitude de centres de dispersion (141) pour disperser de manière élastique le ou les rayons lumineux (S) dans un matériau de base (142) transparent pour le ou les rayons lumineux (S). Chacune des surfaces latérales (123) comporte au moins une couche de réflexion (132) pour réfléchir le rayon lumineux (S) dans le corps d’éclairage (120). La ou les surfaces d’entrée (131) comportent un évidement dans la ou les couches de réflexion (132). La présente invention concerne en outre un procédé de fabrication de l'appareil d’éclairage plan (100).
