Abstract
A lighting device comprising: an elongated laminar substrate having opposed front and back surfaces, one or more electrically-powered light radiation sources, e.g. LED sources, at the front surface of the substrate, a protective encapsulation sealingly encapsulating the substrate and the light radiation source(s), the encapsulation being light-permeable to facilitate propagation of light radiation from the device. The encapsulation includes thermally-conductive material at the back surface of the substrate.
