Sustainable Smart Lighting systems for buildings, latest achievements and future challenges

Résumé

During the last decade, SSLs-Solid-State Lighting based on components like LEDs, OLEDs and LDs, have challenged conventional technologies. In particular, LED has turned into a game changer beating the conventional technologies in all aspects. It is therefore anticipated that within a short time, all electric lighting will be based on SSLs. Today, SSLs are poised to replace all legacy technologies. This is a major change in the lighting market that is considered a revolution.Artificial light absorbs 13-14% of the world’s electricity annual production. Today, we are witnessing a transition from the conventional “analogue” lighting technologies towards “digital” lighting. Smart lighting will become the backbone for smart cities and homes. Smart lighting concept leads towards the heart of the “Internet of Things”. Further, to serve society as effectively as we can, Industry has coined a new term “Integrative lighting” to direct its primary efforts towards meeting human needs. The objective is switching to smart human-centric lighting driven by both “efficiency” and “quality of light”. But this forecast could be severely affected by the “rebound effect” described by Jevons in mid-19th century. Switching to the SSL2 concept, which consists of sustainable smart lighting systems based on solid-state lighting devices, might be one way to stop that harmful effect. Smart, human-centred lighting that incorporates light quality is driven by “appliance efficiency.” This merely suggests that the “Right Light” should be provided by next-generation lighting systems with the best levels of quality and efficiency when and where it is needed. This keynote will highlight all the above-mentioned issues and will focus on the future of the lighting systems and their contributions to the sustainable development of smart cities. The IEEE Smart Lighting Initiative will also be highlighted.
