D4i Standardizes Driver, Sensor, And Controller Connectivity

LCA Director of Education and LightNOW Founder, Craig DiLouie, recently authored an article explaining how D4i helps standardize luminaire level lighting control (LLLC) as one standardized approach to IoT lighting.

By standardizing control and power requirements, D4i makes it much easier to mount sensors and communication devices on luminaires. In addition, intelligent D4i LED drivers inside the luminaire have the capability to store and report a wide range of luminaire, energy and diagnostics data in a standardized format.

Smart D4i luminaires are ideal platforms for the IoT, capable of gathering information from on-board D4i sensors, and providing data for performance monitoring, asset management, predictive maintenance and many other tasks. Communication and data exchange with an external network can take place via a D4i control device with wireless communication capabilities.

D4i is an extension of the DALI-2 certification program. D4i LED drivers have a mandatory set of features related to power-supply requirements and smart-data capabilities. Read Craig’s article on the LCA website here.
