| Abstract | This is a time of revolutionary change in the lighting industry. Solid-state lighting (SSL) systems are on track to achieve lighting efficiencies for general lighting in excess of 150 lumens per watt (lm/W) in the not-too-distant future (see http://www1.eere.energy.gov/buildings/ssl/). This is double the typical performance of the ubiquitous linear fluorescent systems in use today. The total system performance could be further improved by the addition of smart controls, which include occupancy sensing and daylight harvesting, among other features. These controls are easier to implement with SSL systems because of SSL’s digital nature. Interestingly, SSL systems also offer other new functions for interior lighting that have yet to be fully explored. Having started in 2008 to consider what these new functions might be, and how they might be used, our team at the National Research Council of Canada is convinced that further development of these concepts will lead to greater energy savings for lighting, faster adoption of SSL lighting technologies, and improved lighting quality. This summary shows what we think in 2012 that the future will hold |
