CIE TN 012:2021 CIE Technical Note“Guidance on the Measurement of Temporal Light Modulation of Light Sources and Lighting Systems”Full DescriptionCIE Technical Notes (TN) are concise technical papers summarizing information of fundamental importance to CIE Members and other stakeholders, which either have been prepared by a TC, in which case they will usually form only a part of the outputs from that TC, or through the auspices of a Reportership established for the purpose in response to a need identified by a Division or Divisions. This Technical Note has been prepared by CIE TC 2-89 of Division 2“Physical Measurement of Light and Radiation". It has been approved by the Board of Administration and Division 2 of CIE. The document reports on current knowledge and experience within the specific field of light and lighting described, and is intended to be used by the CIE membership and other interested parties. It should be noted, however, that the status of this document is advisory and not mandatory. Any mention of organizations or products does not imply endorsement by the CIE. Whilst every care has been taken in the compilation of any lists, up to the time of going to press, these may not be comprehensive.

ROOT
The topic of CIE 243:2020 is discomfort glare in the context of road and vehicle lighting. It provides an overview of the research methods, mathematical models and the variables which are considered to influence discomfort glare. The report describes the difficulties associated with the evaluation and measurement of discomfort glare and the variance in the models.
One aim of the report is to encourage further research on discomfort glare using methods informed by the proposals raised in this report. Such research will generate a greater body of credible data, thus enabling the development of a more robust model. It is intended to update this report in due course with these additional data and a revised discomfort glare model. [more]
