Machine-readable data for measurements of total luminous flux using goniophotometer: a step toward digitalized metrology

Khaled M. Ahmed, Mohammad D. Almelfi
Abstract:
The transition to digital metrology requires structured and machine-readable data for traceable measurement systems. This article presents a methodology for developing machine-readable data formats IES/LDT for total luminous flux measurements from Type C goniophotometers. A proposed data model aligns with digital calibration certificate (DCC) projects, enabling improved traceability, automation, and interoperability. IES (Illuminating Engineering Society) files are ASCII text files that contain photometric data for lighting fixtures. They are machine-readable and contain detailed information about how light is distributed from a fixture, including luminous intensity, distribution angles, and other relevant information. Lighting design tools and rendering software can use this information to accurately simulate how a fixture would behave in a virtual environment. An actual case study from an SASO-NMCC (National Metrology Institute of Saudi Arabia) illustrates how these methods enhance calibration and function with smart lighting systems.
