CCT TUNING DAYLIGHTING SYSTEM AND METHOD BASED ON LUMINOSITY MEASUREMENTS

摘要

System and method of adjusting a correlated color temperature CCT, of a color-tunable light source (102) based on one or more luminosity (lux) sensors (8a), and without a CCT sensor, comprise receiving, at a controller (104), one or more signals from one or more lux sensors (8a), the one or more signals representative of a luminous flux of natural light (3); determining, with the controller (104), a CCT of the natural light (3) based on, at least in part, the luminous flux of the natural light; and transmitting an output signal from the controller (104) based, at least in part, on the determined CCT of the natural light, the output signal configured to control the CCT of the color-tunable light source (102).
