Luminaires for daylight

M. Knoop

Research output: Contribution to journalArticleProfessional


Daylight and artificial light are two fundamentally different light sources. Daylight is constantly changing. It is dynamic in colour temperature, quantity, direction, ratio of diffuse and direct components, and intensity. These variations are determined by the position of the sun and the weather conditions. Being a point source, the sun produces direct accent lighting with an ever-changing direction, intensity and colour temperature because its position changes throughout the day.
