Combination of Preferred Illuminance and Preferred Color Temperature for Work

Abstract

We have been conducting research on an IntelligentLighting System which is able to provides required illuminance for each worker. In the Intelligent Lighting System, it is possible to provide illuminance and color temperature in an arbitrary location by incorporating chroma sensor into the system. By simply setting a target illuminance and target color temperature, the worker can create the optimal illuminance and color temperature environment for work. However, when setting the target illuminance and target color temperature, selecting the illuminance as well as a color temperature suitable for that illuminance may be difficult for users because it may be unclear which color temperature should be set for the selected illuminance. Thus, in this research we conduct experiments related to illuminance and color temperature, and investigate the combination of preferred illuminance and preferred color temperature for work. By applying the experiment results to the Intelligent Lighting System and simplifying the operations of setting the target illuminance and target color temperature, we aim to improve the level of comfort for worker in the office equipped with LED lighting.

Distributed Intelligent Lighting System by Performing New Model for Illuminance and Color Temperature in the Workplace

“…Therefore, it is common practice in the lighting control system to provide the level of illuminance and color temperature based on the health condition of the user and choosing the time for the system overall [9] [10]. As well as in contribution [11], another approach has been used to measure the color temperature for multiple lights cases.…”
