LED lighting, ultra-low-power lighting schemes for new lighting applications

Publication date: March–April 2018Source: Comptes Rendus Physique, Volume 19, Issue 3Author(s): Marc FontoynontAbstractIn 2018, Solid-State Lighting (SSL) can totally outperform, if properly designed, most of other lighting products used for general lighting applications. This concerns various attributes such as luminous efficacy, life, spectral qualities, dimming potential, and more and more total cost of ownership. SSL can also mimic a large variety of reference light sources from candlelight to sunlight. The absence of international standards concerning LED modules remains the major difficulty for luminaire manufacturers and their clients, since perfectly matching replacement of ever-changing LED modules is not guaranteed over time. But extraordinarily innovative lighting schemes can be developed, bridging the gap between the world of entertainment and the world of general lighting, and leading to new lighting schemes with more powerful emotional content. LED sources, mostly DC driven, also can benefit from progress in photovoltaics and batteries, as well as wireless control to offer integrated solutions. This could radically change the operation of lighting in the next 10 years.RésuméEn 2018, les dispositifs luminescents solides (SSL) peuvent surpasser, s'ils sont correctement conçus, la plupart des autres systèmes d'éclairage couramment utilisés. Ceci concerne différentes caractéristiques telles que l'efficacité lumineuse, la durée de vie, les qualités spect...
