Description
Summary:A Correlated Color Temperature (CCT) measurement and adjustment system based on a microcontroller, an RGBC sensor and a commercially available programmable lighting section was designed as a building block for developing a more complex intelligent lighting system. Because measurement of the CCT can be affected by different errors, in this paper the main sources of error are identified and discussed. CCT calculation relationships based on the RGBC components given by the RGBC sensor, the influence of the illumination level, the influence of the sensor position and the influence of distance between sensor and lighting elements are identified as the main error sources and considerations regarding their decreasing are given.
