Construction of Intelligent Lighting System Using In-office Frames

We focus on office lighting environment and conduct a study of Intelligent Lighting System that provides light brightness in accordance to an individual office workers’ needs. For purpose of commercialization of this system, Intelligent Lighting System using in-office frame was introduced at Kokuyo Co., Ltd. This place is a special work area used for meetings and discussions, etc. Intelligent Lighting System of LED lighting system that consists of 3 types of colors, such as daylight, warm white and umber was used so that illuminance and color temperature could be controlled. Software for illuminance acquisition, user interface software and software for light control were used as control software. The user interface is web-specified, and illuminance, luminance and color temperature can be designated thereon. In system verification of operability of illuminance and color temperature, illuminance was converged in approximately 100 seconds and color temperature of which difference from target color temperature was within 40Kelvin was provided in areas with little impact of outer light.
