摘要

It is necessary to include consideration of the subjective interaction of people with the lit environment into the development of equipment and design strategies for achieving high quality lighting. This requires the development of a theoretical framework that has an equivalent rigour to that which supports research and development in objective, quantifiable aspects of lighting. Cybernetic theory can provide a shared theoretical basis for both objective and subjective aspects of quality lighting. The concept of variety can be used to identify the fundamental differences between the responses to the lit environment of people and of lighting control equipment. It is argued that a quality lit environment is necessarily a high variety one. The law of requisite variety indicates that conventional lighting controls are incapable of maintaining a high quality, high variety lit environment. To develop automatic controls that incorporate high variety responses and control actions, two principal strategies are explored: hierarchical control systems in which the occupants of a building contribute to lighting control and fuzzy logic control systems that simulate the control actions of expert human controllers. The latter type of control would be able to incorporate algorithms reflecting regional and cultural differences in human preferences for what constitutes quality in lighting. To demonstrate the wider application of this theoretical approach, the implications of quality lighting for developments in lamp technology and advanced glazing systems will be briefly explored.
