　　As charted by Brussels-based industry association LightingEurope, HCL will emerge as the top business force in a few years' time, and will continue to gain prominence after that (Fig. 1).

　　Human-centric lighting represents a big part of a necessary sea change in the lighting industry business model, and one that could help ensure a future for the 1000+ companies, 100,000+ jobs, and €20 billion of yearly revenue of LightingEurope member companies, including 33 manufacturers.
