D4i is the DALI standard for intelligent, IoT-ready luminaires. It includes new commands and functions, controllers and control devices are standardized. D4i provides better compatibility between devices from different manufacturers. In addition, intelligent D4i LED drivers inside the luminaire, as well as additional peripheral devices installed both in luminaires and on the pole, can store and transmit a wide range of intelligent data, which allows the standard to be used as a base for smart pole solutions.
