Performance of visible light communications with dimming controls [PDF]
2014 IEEE Wireless Communications and Networking Conference (WCNC), 2014 Visible light communications (VLC) have gained popularity as an alternative to RF. Understanding the underlying communications is key to the design of MAC protocols for arbitrating access across lights in multiple rooms. We consider the interference across two rooms from VLC emitters.

Advanced Dimming Control Algorithm for Sustainable Buildings by Daylight Responsive Dimming System [PDF]
Sustainability, 2018 This study aims to evaluate the accuracy and energy savings of a daylight responsive dimming system (DRDS) when considering the influence of indirect illuminance. In the case of the existing DRDS, during the calibration process of each luminaire, the other luminaires were turned off to detect the illuminance of both the luminaire and the incoming ...
