Connected and Smart LED Lighting for IoT

Connected and smart lighting is a topic that has been getting high momentum during the past few years within the Lighting Industry. Key elements to realize energy savings, as well as new use cases that go beyond lighting controls, are sensors and connectivity.

For energy saving passive infrared sensors – in short, PIR sensors – are used. Novel sensors like radar can overcome weaknesses of PIR sensors like poor design, limited detection of micro-movements, and limited area coverage just to name a few. Radar sensors can be seamlessly integrated into the luminaires enabling nice design as well as platform design of luminaires since there is no need for drilling holes as in the case of PIR sensors.

Advanced use cases like people counting and people tracking can be also ensured with radar technology. In order to add more intelligence into the entire system, connectivity is a key element. Implementation of connectivity provides the following benefits: 

• Cost reduction by implementation of sensor hubs only at very few luminaires that serve as a master for the other luminaires – that serve as slaves
• High computation power of a central control unit can be leveraged that again can serve as a master over all the luminaires
• A central control unit potentially part of the Building Management System (BMS) or cloud can address advanced use cases that go beyond pure lighting control
• Those use cases include asset management, i.e. via people counting the usage of meeting rooms, desks, etc can be analyzed and optimized

Bluetooth® Mesh has become one of the key technologies for Connected and Smart Lighting due to its numerous benefits. One of the key benefits is that Bluetooth® devices that can be deployed as local control elements are ubiquitous. Further benefits are the availability of standardized mature BT mesh stacks and interoperability.
