18 August 2010 Solid state lighting in buildings: status and future
Author Affiliations +
In recent years, there has been considerable press coverage about the promise of Solid State Lighting (SSL). Despite this or perhaps because of the coverage, it can be difficult to separate hype from reality and set expectations for the near to medium term. The short answer is there are good SSL products on the market now and some poor ones. The good ones are getting better, more common, and more affordable. This paper will cover the basics of the key components that make up a luminaire which are LEDs (light emitting diode), power supply, optics, and thermo/mechanical subsystems. Each component will be reviewed with highlights as to what is important. These subsystems will then be considered as a system. Several methodologies for designing both spot and area luminaires will be discussed focusing on non-residential buildings. The topic of SSL lifetime will be discussed. Finally, trends will be explored to provide an understanding of the kinds of improvements one can expect and the timeframe over which they may occur.
