Text Box: 4th Workshop on Lighting: From Energy Efficiency to Light Pollution Supported by CNRI (Romanian National Lighting Committee)   Aim The lighting field suffers a massive transformation. Mainly due to their increased efficiency, LEDs are replacing old lighting technology in practically all application domains. From the conservative skeptical attitudes and up to the aggressive commercial promotion, the specialists are invited to spread information and moderate polemics. But beyond the transition to a new technology, lighting has an increased social, environmental, commercial and cultural role. Different diverse implications of urban lighting have to be analyzed and discussed, like those related to the light pollution: health, ecology, anthropology and the need of a dark sky. Nevertheless, the traditional lighting industry is forced to move away from a product oriented industry, towards an industry providing full service lighting systems and solutions. As a result of the impact of information- and communication technology, new concept like “lighting on-demand” will become usual.   Call for Papers The submission of scientific papers is fully supported. Accepted papers complying with EPE 2020 conditions (http://www.epe.tuiasi.ro/2020/) will be included in the Conference Proceedings, distributed to the participants at the beginning of the Conference. The Proceedings will be submitted to different databases and indexing bodies, including IEEE Xplore and Thomson Reuters ISI Conference Proceedings Citation Index. Proceedings of the 2012, 2014, 2016 and 2018 editions are already available in IEEE Xplore database and are included in ISI Conference Proceedings Citation Index.
