USE OF A COMPACT CCD CAMERA FOR CONTINUOUS MEASUREMENT OF SKY LUMINANCE DISTRIBUTION AND THE CLASSIFICATION OF THE CIE SKY TYPE

摘要

Energy saving is very popular in all areas. In the field of lighting is especially important since power LEDs appeared on the market. LEDs promise almost miraculous savings. Unfortunately, it is seldom aware that you can save energy with proper building design and their good window openings design to ensure minimum dependence on artificial lighting. This means the proper layout, orientation and design of window openings. If we would like to correctly simulate daylight already in the planning stage, we also need relevant information about the sky and the spatial distribution of the luminance of the sky. For this purpose, we developed a new device that enables a stable and continuous measurement of the sky luminance distribution and the classification of the CIE sky type. The article presents the use of a compact CCD camera as a sky scanner and the conclusions.
