IES Standard format including Spectral Data

Post by kikeblackberry » Sun Jul 05, 2020 5:26 pm


Taking into account the implementation of LED light sources for illumination has extended the discussions about color quality, lighting for health, the biological effects of lights, horticultural lighting, and beyond, lighting designers have started to request more information for light source spectral power distribution (SPD) in addition to all the chromaticity related information such as chromaticity values (x,y or u',v'), correlated color temperature (CCT), and color rendering index (CRI). The SPD is an intrinsic physical characteristic of a light source.

For these reasons, the IES has established a new document, TM-27-14, titled "IES Standard Format for the Electronic Transfer of Spectral Data" in order to include within the fotometric file information about spectral data of the source. The data is formatted in accordance with the W3C Extensible Markup Language (XML).

Considering the major goal of TM-27 is to create a unified, industry-standard format for the electronic transfer of spectral data, is it in your road map or in the upcoming evo versions implementing a feature that allow use IES XML format file?

Thank you

Best regards,
