STUDY ON THE ILLUMINANCE BALANCE FOR TASK AND AMBIENT LIGHTING (PART 2): THE INFLUENCE OF LIGHTING CONTROL METHODS ON THE ACCEPTANCE RATES IN A STEADY STATE

This study reports the influence of lighting control methods on the acceptance rates in the relation between the task illuminance T and the ambient illuminance A in a steady state. Additionally, the visual performance and impression are analyzed. The acceptable A in a steady state under each T is predicted with considering illuminance preference by using a prediction method from the previous report which analyzes the acceptable T in a steady state under each T/A. The commonalities and the differences with the previous report, as well as their causes, are discussed.
