well-designed lighting decreases accidents and diseases of eyes and can increase productivity and concentration. increase of energy price and a high proportion of electric lighting energy consumption in buildings due to defects in designing and maintenance led to desirable lighting to be reduced. one of our challenges in providing health and quality of lighting is lack of economic justification...

With the exponential increase of connected products and cheap digital data storage capabilities, applying data analysis and machine learning techniques on commercial datasets has been playing an important role to understand customer behavior. This understanding helps commercial decision-making in various aspects such as suitable time for product promoting or products placement in supermarkets. ...

This paper presents a design for intelligent control system of scene adaptive semiconductor lighting. The new design contains the host computer and the terminal in a control network. The lighting effect patterns are edited by the software on the host computer, then the lighting scene data is transported to the terminal through network. The terminal is a sub-controller based on the embedded syst...

In order to solve the problems of large energy consumption existing in tunnel lighting control system, an automatic control system of tunnel lighting is designed based on stepless control method. The tunnel lighting control model is established based on “Specifications for Design of Ventilation and Lighting of Highway Tunnel (China)”. Simulation of tunnel lighting control based on the establish...

General illumination using LEDs has enabled designers to have precise control of the intensity and color of an illuminated area. In this work, I investigate how these systems can dynamically adjust to create optimal lighting conditions in the built environment. By incorporating environmental feedback into a system control loop, i.e., illuminance or luminance measurements, the precise intensity ...
