| Abstract |
Measurement of daylight is important for evaluation of the lighting conditions in workplaces and for studies of ways to save energy. After a review of theoretical considerations, principles of measurement and characteristics of existing measuring devices, this report presents a new type of apparatus with 2 photometric sensors and describes its application. Schematic diagrams of the various types of apparatus are appended. |
