Abstract: A promlsmg application of the emerging LED technology is traffic signalling, exploiting the norms evolution. The concept is practically illustrated in case of an authentic source for maritime signalling. The new sustainable lamp recombines multiple separated LEDs, realizing a quasi-punctual localized source. The lamp optical design is based on the practical features of the real device and on the relevant norms requirements. After the installation, specific photometric tests verified that the new LED-based source satisfied the illumination requirements. The obtained LED signalling device is more durable and reliable. In future the application of these sustainable sources could be extended to other traffic signalling systems. The aim is to substitute the typical high-consuming short-life lamps with power-saving long-life LED-based sources.
