Book 20:
Smart interface between indoor luminaires and sensing / communication modules

Book 20 defines a smart interface between an indoor LED luminaire and a sensing/communication node. The node connects to the LED driver and control system, and typically can provide sensory inputs or enable communication between network components. Nodes can be installed and replaced in the field.

 

Key benefits are provided for
- luminaire makers, as certified sensors from multiple suppliers are available with a range of different functions
- installers, as certification on interoperability of components exists
- end-users, as the luminaire can be adapted with nodes for different functions, like air quality, presence detection, light levels etc.
