A connected lighting system designed for use in a smart building refers to a networked, intelligent light fixture that is managed in a centralized or distributed way by a building automation system (BAS), building management system (BMS), light management system (LMS), and/or IP-enabled control devices. Commercial, institutional, educational, hospitality and healthcare facilities such as office buildings, hospitals, hotels, malls, warehouses, school and college buildings leverage the growing digitalization and interconnection of physical objects brought about by the Internet of Things (IoT) to deliver new ways of facility management. The accelerating adoption of smart building technology drives the development of innovative lighting products and solutions that can utilize the network infrastructure in the building to contribute to the optimization of building operations. A connected lighting system such as ceiling light, troffer, shop light or recessed downlight is no longer just about sensor-driven and remotely controllable fixture. It participates in IoT transformation of commercial buildings to create an environment of improved engagement, productivity and sustainability.
