Our eldoled dali dimming driver option dims down to 0 1 at minimum light level. Rather several must be linked together to create a. Jiaqi chen general manager moons japan. Usai lighting dali dimming solutions.

Led drivers and ballasts are connected using class 1 inside the conduit or class 2 outside the conduit wiring to make up a loop of no more than 64 led drivers or ballasts. One individual network isn t enough to cover an entire building. However the architecture lighting system in a real project is more complicated than this basic system. A typical dali wiring diagram is shown below.

Today i will introduce the basic construction of the dali lighting system. The system consists of led drivers lighting fixtures controllers dimmers and computers. Dali communication is not polarity sensitive and a variety of connection configurations are possible with this protocol. Originally designed as a successor to 0 10v lighting control dali builds on tridonic s digital serial interface dsi protocol to offer more sophisticated and flexible control where traditional 0 10v control provided messaging in one direction only dali systems can communicate instructions both ways between the control system and each led driver and led ballast device group.
