EMPIR 15SIB07 PhotoLED - Database of LED product spectra

This dataset consists of 1494 relative spectral power distributions (SPD) collected by the partners and collaborators of project EMPIR 15SIB07 PhotoLED - Future Photometry Based on Solid-State Lighting Products. The SPDs of LED products of different types were measured; including AC- and DC-operated bulbs, spots, tubes, street lamps, LED strips, downlight luminaires, prints and textures by a large number of manufacturers. The measurements of the products were carried out in various laboratories, including manufacturers of LED products, test laboratories, and National Metrology Institutes (NMI). The products included in the study were manufactured in the timespan of 2009–2016. Due to the sensitivity of the data, the individual sources of data have been anonymized, the authors retain this information as confidential. The SPDs are numbered S with n between 1 and 1495, sorted by the correlated color temperature (CCT) calculated using equation published by MacCamy in 1992. The data was used in the analysis of LED illuminants and reference spectra for photometer calibration that has been published as a scientific paper Alexander Kokka et al.
