Bridgelux Develops a New Metric to Quantify the Naturalness of Light

Bridgelux today announced development of a new metric to enable objective comparisons of light sources to natural light. With the growing market interest in human-centric lighting, the question of “naturalness” of light source spectra is becoming a frequently asked question. Standard lighting quality metrics such as CRI and TM-30 do not fully address the naturalness question. The Average Spectral Difference (ASD) metric has been developed by Bridgelux to address this shortcoming in available light quality metrics. Read more »

University of Manchester Scientists Suggest Blue Light Not So Disruptive to Sleep as Thought

Contrary to common belief, blue light may not be as disruptive to our sleep patterns as originally thought. According to the team, using dim, cooler, lights in the evening and bright warmer lights in the day may be more beneficial to our health. Twilight is both dimmer and bluer than daylight, they say, and the body clock uses both of those features to determine the appropriate times to be asleep and awake. Read more »

Tailored Light Improves Sleep Quality, Depression, Agitation in Older Adults with Alzheimer's Disease

Most people associate Alzheimer's disease with profound memory loss, but it is often the symptoms - sleep disturbances, depression, and agitation - that are a challenge to treat, and can significantly reduce the quality of life for both the affected individual and their family members and caregivers. In a research project funded by the National Institute on Aging (NIA), Dr. Mariana Figueiro, Professor and Director at the Lighting Research Center (LRC) at Rensselaer Polytechnic Institute, is investigating whether a tailored lighting intervention can lessen the impact of these symptoms in older adults living with Alzheimer's disease and related dementias (ADRD).

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

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 »
