DALI-2 Smart Data

DALI-2 Smart Data

DiiA has standardized the storage and reporting of data in control gear (e.g. LED drivers). Data is used for enhanced asset tracking and performance monitoring. The DALI-2 Smart Data specifications for control gear are listed below:

DALI Part 251 – Memory Bank 1 Extension (luminaire data) Version 1.1, October 2019 Download specifications here
DALI Part 252 – Energy Reporting Version 1.1, October 2019
DALI Part 253 – Diagnostics & Maintenance Version 1.1, October 2019

Data relates to the light source, the driver and the luminaire. The data is stored in DALI memory banks, with a standardized format and locations. The availability of DALI-2 Smart Data enables smart luminaires that are able to participate in the IoT.

DiiA Part 251 – Memory Bank 1 Extension (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.
DiiA Part 252 – Energy Reporting
  • Active energy/power
  • Apparent energy/power
  • Load-side energy/power
DiiA Part 253 – Diagnostics & Maintenance
  • 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.
