Comparison of lighting simulation outcomes for electric lights with real reference

Abstract

In recent years, there has been considerable progress in the area of building lighting [1]. Especially in terms of efficiency, durability, and internal lights control possibilities offered by the system. Besides these affairs were conducted further studies focusing on the visual comfort in the indoor environment. The fact is that a considerable number of issues causing some visual discomfort can be solved by appropriately modifying the control logic of the system. For these reasons, a suitable way to control the lighting in this field is crucial. The design of control algorithms can be done in various ways, however, in recent years, very useful tools for performing complex lighting assessments are simulation tools [2]. This article deals with a comparison of the results of simulation tools and real measurements and further discusses the possibilities of using these tools to design lighting control algorithms. This article also describes a newly built lighting laboratory at Tomas Bata University in Zlin whose control system is based on the KNX bus and its components. The primary purpose of this laboratory was to study the interaction of natural and artificial lighting in the view of uniform illumination on the workplace and chromatic distribution through the room. However, as the lab control system is conceived, it is a prerequisite to using the laboratory to verify the various control algorithms based on both direct and feedback control. © 2018, World Scientific and Engineering Academy and Society.
