A substantially flexible, electro-luminescent light source is presented. The light source comprises an electrodes' assembly, dielectric and electro-luminescent layers, and at least one outer, substantially flexible layer formed of insulating transparent material. The light source is provided with a heating element, and a power supply unit coupled to the electrodes' assembly and to the heating element. The power supply unit selectively operates the electrodes' assembly and the heating element, such as to heat the vicinity of the electrodes' assembly thereby maintaining desired temperature conditions in the vicinity of the light source and thereinside.

Flexible electro-luminescent light source with active protection from moisture

An illumination system for illuminating an underwater space is presented. The system comprises an elongated flexible electroluminescent light source located substantially inside the underwater space and a power supply unit located outside the underwater space. The power supply unit is connected to one end of the electroluminescent light source. At least this one end of the light source, which is connected to the power supply unit, is located outside the underwater space. The light source has at least one light-emitting element located inside an inner insulating sheath, and has an outer insulating sheaf. The inner insulating sheath and the outer insulating sheath are separated by a continuous air gap coupled to an air region outside the underwater space. This prevents the light source from being affected by water, and thereby from the reduction of its lifetime.

Aquarium lighting system

There is provided a light source consisting of at least one flexible, cable-like electroluminescent filament, each filament having a central electrode (2) surrounded by an electrically insulating dielectric layer (4), and a layer (6) consisting of a mixture of an electroluminophor powder and a binder. The mixture is applied to the dielectric layer (4). The light source also includes a transparent electrode (8) surrounding the mixture layer (6). Pores formed in the mixture layer (6) are filled in by a transparent filler substance. A method for preparing the light source is also provided.

A cable-like electroluminescent light source comprises at least two electrodes mutually disposed in such a way as to create between them an electric field when a voltage is applied to them; at least one type of pulverulent electroluminophor dispersed in a dielectric binder and disposed in such proximity to the electrodes as to be effectively excited by the electric fields when created and to emit light of a specific color, and a transparent polymer sheath encasing the electrodes and the electroluminophor.
