Digital Addressable Lighting Interface (DALI) is a trademark for network-based systems that control lighting in building automation. The underlying technology was established by a consortium of lighting equipment manufacturers as a successor for 0-10 V lighting control systems, and as an open standard alternative to Digital Signal Interface (DSI), on which it is based.
A DALI network consists of a controller and one or more slave devices (e.g., electrical ballasts, LED drivers and dimmers) that have DALI interfaces. The controller can monitor and control each device by means of a bi-directional data exchange. The DALI protocol permits devices to be individually addressed and it also allows multiple devices to be addressed simultaneously via multicast and broadcast messages.
Dimmer is a controller that it can adjust brightness infinitely, its control mode is knob-operated control, you could adjust light to the appropriate lighting brightness in accordance with your actual need.
RF dimmer is a controller that can adjust brightness infinitely and change to flash, its control mode is wireless control, you could adjust light to the appropriate lighting brightness in accordance with your actual need.
LIGHTIFY control connects smart devices with LIGHTIFY lamps, luminaires and components, connects up to 50 LIGHTIFY products, intelligent wireless light control.
