DALI (Digital Addressable Lighting Interface) is a digital communication protocol designed to control lighting systems intelligently. It enables a controller to communicate individually with each luminaire or connected device via a single two-wire bus. <\/p>\n

DALI is an open, bidirectional protocol; it is a digital language used worldwide to control lighting components such as LED drivers. It enables the transfer of information and dimming commands, fault data and diagnostics between different devices.  <\/p>

DALI-2 is the latest version of DALI. It offers improved interoperability between products from different suppliers thanks to mandatory certification and provides additional features, such as energy consumption data; but, above all, it now includes control devices that were not included in the original DALI. <\/p>\n

What is it for?<\/h2>\n

With DALI, you can:<\/p>\n

    \n
  • Switch lights on and off.<\/li>\n
  • Adjust the light intensity (dimming).<\/li>\n
  • Create groups of lights.<\/li>\n
  • Save and activate lighting scenes.<\/li>\n
  • Control the RGB colour and colour temperature (on compatible lights).<\/li>\n
  • Monitor the condition of each piece of equipment and detect faults.<\/li>\n
  • Reconfigure the installation without having to alter the wiring.<\/li>\n<\/ul>\n

    How does it work?<\/h2>\n
      \n
    • It uses a 2-wire communication bus, independent of the mains power supply.<\/li>\n
    • Each device has a unique address (up to 64 devices per DALI line).<\/li>\n
    • A DALI controller sends digital commands to the connected devices (LED drivers, sensors, push-button switches, touchscreens, etc.).<\/li>\n<\/ul>\n

      Components of a DALI system<\/h2>\n
        \n
      • DALI controller (the system\u2019s brain).<\/li>\n
      • DALI-compatible LED drivers.<\/li>\n
      • Presence or light sensors.<\/li>\n
      • DALI push-buttons or touchscreens.<\/li>\n
      • DALI bus power supply (already built into many controllers).<\/li>\n<\/ul>\n

        Advantages<\/h2>\n
          \n
        • Individual control of each light fitting.<\/li>\n
        • Flexible installation that is easy to expand.<\/li>\n
        • Energy savings through automation.<\/li>\n
        • Integration with presence and natural light sensors.<\/li>\n
        • Option to create scenes and schedules.<\/li>\n
        • DALI bus power supply (already built into many controllers).<\/li>\n<\/ul>\n

          Applications<\/h2>\n
            \n
          • Offices.<\/li>\n
          • Hotels.<\/li>\n
          • Hospitals.<\/li>\n
          • Shopping centres.<\/li>\n
          • Industrial buildings.<\/li>\n
          • High-end smart homes.<\/li>\n
          • Vial.<\/li>\n<\/ul>\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t
