Hi Dear colleagues, dear development team!

The DiaLux calculation surfaces described "Vertical illuminance" in wrong manner!

My statement is based on the CIE publications CIE S 017/E:2020 ILV: International Lighting Vocabulary, 2nd Edition STANDARD by Commission Internationale de L'Eclairage, 12/01/2020

The short tsitation with help AI: The International Lighting Vocabulary (ILV) is a standard published by the International Commission on Illumination (CIE) that provides definitions and essential information necessary for the understanding and correct usage of terms related to light and lighting, color and vision, photobiology, and image technology 1. The term “perpendicular illuminance” is defined in the ILV as “the illuminance on a surface when the normal to the surface is perpendicular to the direction of incidence of the luminous flux”

It means: there is nothing do deal with DiaLux definition in Parameters of a calculation object : Knowledge Base DIALux evo

The same time I continue to wait for the development team to correct errors or eliminate misleading information. Üllar Võrno🥸
