Optimization of the Height of Height-Adjustable Luminaire for Intelligent Lighting System

We are doing reseaching and development of an intelligent lighting system to provide desired brightness to a desired place. In this study, we consider how to satisfy target illuminance for each worker and minimize power consumption with not only luminous intensity for each light but also the height of luminaire as the design variables. Therefore, highly-accurate target illuminance as well as very high illuminance can be realized and further energy saving is achieved.
