ABSTRACT:
An electroluminescent light source has a core member and a pair of transparent band structures between which the core member is sandwiched and which in an assembled state form a transparent sheath. The core is formed by a plurality of elongated electrodes spaced from each other and interconnected by means of connecting bodies of a dielectric material. Spaces between the electrodes are filled with an electroluminescent material which is applied in the form of a film onto the connecting bodies. The entire system of electrodes is placed between a pair of electroconductive buses to which the electrodes are connected electrically and which support the system of electrodes through dielectric separating blocks. In order to provide dynamic light effects (e. g., "traveling light") the electrodes may be combined into separate isolated groups arranged lengthwise or widthwise with electrical connection of each group to a respective electroconductive bus via a switching device. A method of manufacturing of the light source of the invention includes two stages: forming a core and transparent band structures in two separate but simultaneous processes, and assembling the premanufactured units by sandwiching the core between a pair of band structures.
