CA 2599457

The invention relates to a flat illuminating device (10, 10') which comprises light-emitting illuminating elements (1) which are arranged on a carrier and which are connected to the current supply lines and current discharge lines (4') for supplying current.Said support is shaped as a metallic film (2) which is covered with an insulating layer (3), whereon series circuits consisting of an illuminating element (1) and a series resistor surface (5) are arranged, respectively between the current supply lines and the current discharge lines (4'). An illuminating element (1) and a series resistor surface (5) of a series circuit and series circuits and current supply lines and current discharge lines (4') are connected together via conductor paths (4). The invention also relates to a method for producing said type of illuminating devices.

Dispositif d'éclairage plat (10, 10') pourvu d'éléments d'éclairage (1) émetteurs de lumière placés sur un support et connectés à des lignes d'alimentation et de sortie électriques (4') destinées à l'alimentation en électricité. Le support possède la forme d'une feuille métallique (2) couverte d'une couche isolante (3) sur laquelle des couplages en série constitués chacun d'un élément d'éclairage (1) et d'une surface de résistance série (5) sont placés entre les lignes d'alimentation et de sortie électriques (4'). Un élément d'éclairage (1) et une surface de résistance série (5) d'un couplage en série, ainsi que les couplages en série et les lignes d'alimentation et de sortie électriques (4') sont connectés les uns aux autres par des pistes conductrices (4). La présente invention concerne en outre un procédé de fabrication de dispositifs d'éclairage de ce type.
