The Research on Testing and Standardization of Circadian Rhythmic Spectrum Technology of Indoor Dimming Lighting Products

This paper introduces the standardization of Specification for evaluation circadian rhythm spectrum technology of indoor dimming lighting products. Melanopic efficacy of luminous radiation and melanopic daylight(D65) efficacy ration (MDER) are first specified in the new published China solid state lighting alliance (CSA) standard. It also researches on the testing and evaluation of some circadian rhythm spectrum parameters in different lighting products. Through the testing of circadian rhythm parameters and standardization of lighting products, some spectrum related requirements were also given of circadian rhythm parameters evaluation in the T/CSA 083–2024 group standard<sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">[1]</sup>.
