Define “Smart Lighting”Smart lighting is a lighting technology designed for energy efficiency.This may include high efficiency fixtures and automated controls thatmake adjustments based on conditions such as occupancy or daylightavailability.WikipediaSynthesizing Light for the Benefit of HumanityImagine a world where efficient, digital lighting makes us healthierand more productive, produces significant energy savings, andprovides wireless, optical access to the internet.
A more comprehensive definition What most people call smart lighting is "Smart Thinking aboutLighting Systems" while what the ERC is looking to do is create"Smart Lighting Systems that Think".By looking at lighting systems holistically (from the systemfunctionality down to the nanoscale details of light generation anddetection), we are looking at how to create efficient lighting systemsthat: (a) "see" where the light is going and what it is doing, (b)communicate using light to send information and enable lightinginformation processing, and (c) have novel control systems that"think" about what the light needs to be doing to meet theexpectations and requirements of people.Robert Karlicek
