Towards “Lighting 4.0” era: from the LED technological revolution to the “Sustainable Smart Lighting” concept


During the last decade, SSLs-Solid-State Lighting based on components like LEDs, OLEDs and LDs, challenges conventional technologies. LED has turned into a game changer beating conventional technologies in all aspects. Today, SSLs proceed to replacing of all legacy technologies: a revolution in the lighting market. Artificial light production absorbs around 2 900 TWh corresponding to 13,7% of the world’s electricity annual production. The massive adoption of LED technology during the next years can contribute to harness electricity use for lighting, up to 4% by 2030. As LED technology matures, maximizing the energy savings from connected SSL systems will become increasingly dependent on successful integration into the built environment. Today, we are witnessing a transition from the conventional “analogue” lighting technologies to “digital” lighting. Intelligent lighting will become the backbone for smart homes and smart cities. Industry has coined a new term “integrative lighting” to draw renewed attention to its primary effort to be successful in meeting society’s needs. However, “rebound effect”, known also as “Jevons paradox”, can blur this march forward. One potential solution to avoid that negative effect consists in switching to smart integrative lighting driven by both “application efficiency” and quality of light. This technological revolution shall comply with the SSL2 concept, which consists of sustainable smart lighting systems based on solid-state lighting devices, might stop that harmful effect. Smart, and affordable integrative 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.
