Implementation to Provide Individual Illuminance and Color Temperature in an Intelligent Lighting System by Estimating the Color Temperature

摘要

We are conducting research and development of the Intelligent Lighting System providing illuminance and color temperature individually to workers at an office. Under the Intelligent Lighting System, a chroma meter is placed on the desktop of each worker in order to measure illuminance and color temperature. It is not easy to introduce the system to a real office, however, as a chroma meter is expensive. This study thus proposes a new method for providing illuminance and color temperature individually to each worker by estimating instead of measuring color temperature. It eliminates the need to use a chroma meter and contributes to enhancing the ease in introducing the Intelligent Lighting System. A verification experiment was conducted to show that illuminance and color temperature can be individually realized at the same precision as when a chroma meter is used.
