Update on Status of Solid-State Lighting & Smart Lighting Systems
Assessment of latest energy efficiency progresses and world market in solid state and smart lighting
Today, lighting is responsible for 5% of worldwide CO2 emissions. Electricity demand for lighting attained 2900 TWh for a global light production of 134 Plmh. It is foreseen that in 2040 the needs for artificial lighting will increase by 50%. The challenge for the next decade will be to harness the increase of electricity demand. The only light source technology evolutions are not sufficient to stem uncontrollable growth. Today the best commercialised LED lamps are almost 2 times more efficient than fluorescent tubes. This is not sufficient to inhibit the well-known rebound effect. Only a transition from the conventional analogue lighting technologies to digital lighting can help. Smart lighting will become the heart of the Internet of Things in smart cities and buildings. However, only the Sustainable Smart Lighting SSL2 concept introduced in this report solve the above-mentioned issues. Global lighting market revenue reached €130 billion and it is growing steadily with a 10% CAGR till 2025. Today, LED technology share is higher that 50% and it expected to reach 85% by 2035. Smart Lighting is on the way to become the 4th revolution in the domain. It can achieve more than 40% additional energy savings and the market size can exceed €90 billion by 2030. Finally, the report illustrates the effect of some regulations and policies have as objective to harness uncontrollable increase of lighting and protect the ecosystem from some collateral damages.
