Measurement device for light pipe evaluation

Abstract

Two types of light pipes of comparable dimensions were tested. The evaluation of light guides was based on data of long-term measurements of daylight illuminance. A set of illuminance meters distributed on the reference plane under the light pipes were used. The illuminance measurements were processed using a data collecting system. The system collected data for one-year continual measurements. The measured data analysis shows differences in the tested light pipes daylighting which is relevant to their practical applications.Two types of light pipes of comparable dimensions were tested.
