Smart Lighting Control Systems

Abstract

In this chapter , we turn our attention to another subsystem in an intelligent building, the illumination (or lighting) system. While traditional lighting systems were designed to provide illumination for the occupants of the building, with the advent of light-emitting diode (LED) technology, lighting systems are now far more sophisticated and responsive to the needs of the occupants. In this chapter, we first present a broad overview of modeling and control strategies for smart and autonomous lighting systems. One of the key challenges in development of lighting control strategies is the lack of standardized test scenarios, benchmarking, and the wide diversity of available hardware. To highlight this, we will describe and compare four lighting control algorithms that are applicable for different lighting scenarios and compare and contrast them. We also demonstrate and benchmark these algorithms on a full-scale testbed (a conference room). Finally, we present a decision tree to guide the reader on the choice of a suitable lighting control scheme.
