DALI (Digital Addressable Lightning Interface) is a protocol that allows communication between the end elements of an installation (in this case, luminaires) and the control system, regardless of the technological solutions used. Created as an alternative to traditional control systems based on 1-10V, it allows control of individual luminaires, or a specific group, using peripheral devices or a PC using a single two-wire cable. The digital addressing protocol (DALI) is a modern way to control lighting. In cooperation with dedicated devices, it becomes ideal for use in intelligent installations in all kinds of buildings. The construction, features and capabilities bring to mind that it is a universal system with very high potential for expansion and designed to work with any type of lighting, which makes more and more companies reach for solutions in this field.
