Abstract

Bei einer Elektrolumineszenz-Leuchtanordnung mit einem Trägersubstrat (1) aus einem elektrisch isolierenden Material, auf dem sich eine elektrisch leitende Schicht befindet, aus der wenigstens zwei elektrisch voneinander isolierte Leitbahnbereiche herausgearbeitet sind, die eine erste Elektrode (3) und eine zweite Elektrode (5) bilden und von einer Pigmentschicht (14) überdeckt werden, deren dotierte Pigmente beim Anlegen einer Wechselspannung an die beiden Elektroden leuchten, ist zur Steigerung der Leuchthelligkeit vorgesehen, daß die Pigmentschicht (14) zumindest in einem Teilbereich ihrer Fläche mit einer dünnen, transparenten, elektrisch leitenden Deckschicht (16) überdeckt ist, an welche im Betrieb von außen keine zusätzliche Spannung angelegt wird.

Figure 00000001
In an electroluminescent light-emitting arrangement with a carrier substrate (1) of an electrically insulating material on which there is an electrically conductive layer, from which at least two electrically insulated conductive track areas are worked out, which comprise a first electrode (3) and a second electrode (5 ) and covered by a pigment layer (14) whose doped pigments illuminate when applying an alternating voltage to the two electrodes, is provided to increase the luminous brightness that the pigment layer (14) at least in a portion of its surface with a thin, transparent, electrically conductive cover layer (16) is covered, to which during operation no additional voltage is applied from the outside.
