Implementation to Provide Individual Illuminance and Color Temperature in an Intelligent Lighting System without Chroma Meter

摘要

The authors have conducted research into an Intelligent Lighting System in order to achieve the illuminance and color temperature levels required by each office worker with low power consumption through the use of a chroma meter. However, as these chroma meters are very expensive, it is not easy to introduce them into offices. For this reason, we have proposed a new method for an Intelligent Lighting System that achieves separate color illuminance and color temperature for the specified location, without using a chroma meter. In verification experiments demonstrating the effectiveness of the proposed method, we have performed comparative experiments between methods using chroma meters and the proposed method. It was possible to achieve the illuminance/color temperature required by each office worker, when the illuminance sensors are separated by more than twice the lighting placement interval.
