A New Approach to Lighting System Control

In recent years, the number of switches for lighting system control has been reduced to save initial installation costs. In commercial buildings, large areas or even whole floors may have only one or two switches for the entire general lighting system. The author examines the development of a practical low cost lighting control system that can vary the illumination within an exterior or interior space. The system is designed to suit the changing needs of the lighting user, conserve energy, and lower lighting costs.
