Healthy Light - LED Technology for Health and Care Applications
Healthy Light - LED Technology for Health and Care Applications The right light, at any time during the day or night, is absolutely essential for health and well-being especially in health and care applications. Peter Haumer, Head of Technical Sales at Lumitech/Kiteo reveals why, besides full spectrum and high color rendering, mimicking real daylight conditions with extended daylight curves, a direct and an indirect component (CCT 1.800–16.000 K), are essential. The article discusses the benefits that can be derived from special colors for medical staff, patients and residents. 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 »

PerfectWhite: Luminus’ Latest Spectrally Tuned COB
PerfectWhite: Luminus’ Latest Spectrally Tuned COB Spectrally tuned sources are the essential components of human-centric lighting and Luminus PerfectWhite is it’s newest source, joining the Sensus and AccuWhite products, that has been purpose-designed and improves upon the light from conventional sources. PerfectWhite™, which closely replicates the visual characteristics of halogen lamps (3000 K) was preferred by lighting designers in testing at both Light + Building and Lightfair. Though the spectrums are a virtual match – Luminus filled the cyan gap – PerfectWhite’s color point is slightly below the black body locus and as a result, there’s no green/yellow tint that is common to halogen. A better halogen has long been a wish of the lighting design community and PerfectWhite delivers without infra-red, without green/yellow tint, and without ultraviolet radiation. Read more »

A Near Infrared Enhanced LED Lighting Approach
A Near Infrared Enhanced LED Lighting Approach With the evolution of LED lighting, one topic has come more and more in the focus of the lighting industry: Human Centric Lighting (HCL). While HCL is not clearly defined, a common understanding is that this is light and lighting that supports health and the well-being of humans. Some new proposals are going beyond the approach of providing just visible light in adequate quality, but also to providing invisible radiation, UV and/or NIR that support health and well-being. Some research and the evolution of humans show clear evidence for positive effects of this kind of illumination. Scott Zimmerman, CEO at Silas, presents a new approach that adds NIR radiation to LED illumination. He explains the background of this idea, how it also improves the quality of visible light and discusses the health benefits. Read more »

Tech-Talks BREGENZ - Fred Maxik, Founder & CTO, Lighting Science Group LED light in combination with advanced controls, and here especially IoT capabilities, opened several new options in lighting. In this context, the term Human Centric Lighting, and more recently, the term Biologically Active Light have become trendy. Fred Maxik, founder and CTO of the Lighting Science Group, who held the keynote speech at LpS 2017, recognized these opportunities in a very early stage when most other manufacturers were still struggling with the challenges of the new technology. In the interview he explains what his perception of light is and its importance in our lives. He gives insights into his philosophy and ideas on which criteria artificial lighting has to fulfill in order to live up to the promising terms „Human Centric Lighting“ and „Biologically Active Light“.

New LRC Study Tests the Impact of Circadian Light on Alertness in Office Workers
New LRC Study Tests the Impact of Circadian Light on Alertness in Office Workers In 2017 the Lighting Research Center (LRC) at Rensselaer Polytechnic Institute published a groundbreaking study showing that office workers who receive a robust dose of circadian-effective light experience better sleep, and lower levels of depression and stress, than those who spend their days in dim or low light levels. The team of LRC researchers, led by Dr. Mariana Figueiro and sponsored by the U.S. General Services Administration, measured existing light levels for 109 participants at five federal office buildings designed to maximize daylight availability indoors. The research team found that even in open offices with many, large windows, office workers were not receiving enough light to stimulate their circadian system during the day, due to factors such as season, cloud cover, desk orientation, and window shade position.
