DALI-2 Data

DALI-2 Luminaire, Energy & Diagnostic Data

DALI-2 has standarized the storage and reporting of a rich set of data for enhanced asset tracking and real-time performance monitoring.

Data relates to the light source, the LED driver and the luminaire. The data is stored in DALI memory banks in the driver, with standardized formatting and locations.

The availability of DALI-2 Data enables smart luminaires that can participate in the IoT.

DALI-2 Luminaire Data

Includes luminaire data such as:

  • luminaire supply power & voltage
  • light output,
  • CCT & CRI,
  • light distribution
  • luminaire colour, and more.

Usage example: A manufacturer can encode data about the luminaire in the factory. When the luminaire is installed, the data is readily available to the lighting-control network. A utility company or lighting-installation owner could use this capability for automated commissioning, and to monitor and manage their lighting assets accurately and efficiently.

DALI-2 Energy Data
  • Active energy/power
  • Apparent energy/power
  • Load-side energy/power
DALI-2 Diagnostics Data
  • Failure conditions for control gear and lamps, including counters.
  • Control gear information: Operating time, start counter, supply voltage and frequency, power factor, temperature and output current.
  • Light source information: Operating voltage, current, temperature, light source start counter, light source on time.
