Providing Individual Illuminance and Color Temperature in an Intelligent Lighting System Without Using a Chroma Meter

The authors have conducted a research on an Intelligent Lighting System with low power consumption, that achieves an appropriate illuminance and color temperature for individual offi ce workers by using a chroma meter as a sensor. However, as these chroma meters are expensive, it is not easy to introduce them into offi ces. For this reason, we have proposed a new method for an Intelligent Lighting System that achieves individual illuminance and color temperature without using a chroma meter. To verify the effectiveness of the proposed method, we have performed a comparative experiment between the method using a chroma meter and the proposed method. From the experiment, it was possible to achive an appropriate illuminance and color temperature for individual offi ce worker, when the sensors were separated.
