DALI Lighting Control System

The new method involves using open system of DALI-protocol-based technology (i.e. digital control signals) to control electronic ballasts, controllers and sensors belonging to the system. Each system component has its own device-specific address, and this makes it possible to implement individual device control.

It brings the benefits of a new industry standard to lighting-control systems and has been developed specifically with optimum lighting control in mind, both in local room control applications and when interfacing with building management systems. The DALI protocol, based are a draft amendment to IEC 929, has been adopted as a new standard by major ballast manufacturers such as Helvar, Hüco, Philips, Osram, Tridonic, Trilux and Vossloh-Schwabe. As a dedicated communication interface for the control of lighting systems, DALI enables sophisticated lighting control while greatly increasing flexibility and reducing installation costs.
