Abstract
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.
