An Intelligent Lighting System to Speed up Illuminance Convergence by Dynamically Classifying the Relationship between Illuminance Sensors and Lights

Intelligent Lighting Control Using Correlation Coefficient between Luminance and Illuminance

An intelligent lighting system which provides required illumiancne at an appropriate location is proposed. This system does not have the centralized control device and also it is controlled by each intelligent lighting’s autonomous operation. Also the intelligent lighting system can contribute to energy saving. In this research, a new algorithm is proposed. For rapid converges it uses the corre...

Distributed Control of Illuminance and Color Temperature in Intelligent Lighting System

This reserch proposes a method to provide an appropriate illuminance and color temperature in an office lighting environment for individual workers. For the control algorithm, based on the optimization method called Simulated Annealing (SA), a method including a neighborhood design mechanism for the design variables instead of a temperature parameter was used. In addition, for changes in the lu...

Construction of Intelligent Lighting System Providing Desired Illuminance Distributions in Actual Office Environment

An Intelligent Lighting System providing desired illuminance distributions at minimum electrical power was constructed in the actual o ce environment. The place of construction is the Area Planning O ce in the headquarters building of Mitsubishi Estate Co., Ltd. in Otemachi, Tokyo. The oor area is about 240 square meters, and 26 lighting xtures and 22 illuminance sensors are installed. One ligh...

Overall Illuminance Uniformity of IRED Lighting in Nighttime CCTV

LEDs (light-emitting diodes) are superior to the conventional light bulbs and florescent lights in terms of low power dissipation, high efficient and longer lifetime. Therefore, conventional light bulbs are gradually being replaced by LED light bulbs as the next generation lighting source. LEDs are also playing more important roles in industrial applications, such as backlighting in LCD display...
