CIE Position Statement on Non-Visual Effects of Light - 2nd Edition

CIE Position Statement on Non-Visual Effects of Light - 2nd Edition On October 3rd, CIE released their new position statement on non-visual effects of light, entitled "Recommending Proper Light at the Proper Time" 2nd edition. As non-visual effects are becoming more attention nowadays, confusion and uncertainties on this topic are still high in the lighting community. Much research has been done but even more research is necessary. CIE has recognized this relevant topic and already initiated an independent workshop of leading scientists in the field of quantifying light for non-visual effects in Manchester in 2013 (CIE TN 003:2015 (CIE 2015)). The CIE issued an international standard, CIE S 026:2018 (2018), that defines a system for metrology of optical radiation for light-induced responses that can be elicited by ipRGCs (ipRGC-influenced light (IIL) responses).

Circadian-Friendly Light Emitters: From CCT-Tuning to Blue-Free Technology

Circadian-Friendly Light Emitters: From CCT-Tuning to Blue-Free Technology Common levels of blue radiation are sufficient to disrupt the circadian cycle, calling for blue-depleted emitters in the evening. Most current solutions employ low-CCT and suffer from poor light quality. Aurelien David, chief scientist at Soraa explains the melanopic lumen and its possible sources of inaccuracy related to the uncertainty in assessing the circadian action spectrum. In addition, he also discusses the concept of a blue-free emitter with minimal melanopic lumen at very low CCT and how such a spectrum providing a good light quality can be optimized. Read more »

Melanopic Green - The Other Side of Blue

Melanopic Green - The Other Side of Blue LpR 71 Article - page 74: For years now, there has been a controversial discussion about the amount of blue light in LEDs. Medical studies have shown that, depending on the amount, blue light at night disrupts the circadian rhythm. As a result, warm white (<3000 K) light sources are often touted as a solution for street lighting as well. Ian Ashdown, P. Eng. (Ret.), FIES Senior Scientist at SunTracker Technologies discusses whether or not it is sufficient to only look at the CDT or if other wavelengths and aspects should be considered. Numerous medical studies have shown that exposure to blue light at night suppresses the production of melatonin by the pineal gland in our brains and so disrupts our circadian rhythms. As a result, we may have difficulty sleeping. It is therefore only common sense that we should specify warm white (3000 K) light sources wherever possible, especially for street lighting. - True or false? Read more »
