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.

National Lighting Bureau: AMA Lighting Recommendations are Based on Wrong Metric

National Lighting Bureau: AMA Lighting Recommendations are Based on Wrong Metric The American Medical Association’s (AMA’s) warnings about too much “blue light” at night are seriously flawed: The AMA developed them using a measuring tool that does not measure the specific kind of “blue light” the AMA is concerned about. Nonetheless, according to speakers at the National Lighting Bureau’s Annual Lighting Forum, some jurisdictions and public-transportation departments nationwide believe, mistakenly, that they will reduce human-health risks by adopting the AMA’s recommendations. Making matters worse, when applied to street and roadway lighting, the AMA recommendations could erode public safety by diminishing driver and pedestrian visibility, while also reducing energy efficiency or increasing energy costs.

Lighting-for-Seniors Study Hints that “Tunable” White LED Light Has Positive Effects

Lighting-for-Seniors Study Hints that “Tunable” White LED Light Has Positive Effects Disturbed sleep patterns are common among the residents of senior-care facilities, due to the aging process and diseases like Alzheimer’s. Could lighting make a difference? That’s the question that the Sacramento Municipal Utility District (SMUD); the ACC Care Center, also in Sacramento; and the U.S. Department of Energy (DOE) decided to answer, at least on a preliminary basis, by replacing some of the Care Center’s fluorescent lighting in one corridor, two resident rooms (including bathrooms), the nurse station, the common family room, and the administrator’s office.

DoE Releases OLED Market Report for 2016 The latest DoE market report for OLEDs sounds much more modest than some older market reports when DoE concludes in the management summary: With rapid advances in these areas, this technology could become the complementary solid-state counterpart to LEDs, a dynamic and softly luminous luminaire element and building material. On the positive side, DoE states that while OLEDs are struggling through a similar set of difficulties like LEDs did in the early years, OLED manufacturers have the advantage of having watched and learned from the LED industry’s working through these problems.

IEA Issues Final Report on Potential Health Issues Related to Solid-State Lighting

Not just the 8 displayed LEDs have emission spectra falling into the action spectrum of the "Blue Light Hazard" (black curve). A part of the emission spectrum of practically any natural or artificial light source falls in this range around 437nm Recently, the governments of ten countries announced the publication of a comprehensive review of the current literature relating to human health impacts of solid-state lighting (SSL). This review evaluates whether energy-efficient LED systems are a safe light source to illuminate our homes, buildings and outdoor areas. The review concluded that SSL technology is not expected to have more direct negative impacts on human health with respect to non-visual effects than other lighting technologies. For electromagnetic fields, human exposure emitted by SSL products does not appear to be a critical issue as their magnitude is generally much smaller than those corresponding to discharge lamps or certain household appliances. The report also provides advice on flicker and glare. Read more »

Lighting Research Center Authors National Academies Report on New Roadway Lighting Technologies

The rapid development of lighting technologies, particularly solid-state systems using light emitting diodes (LEDs), has opened a universe of new possibilities as well as new questions about roadway lighting in the U.S., which for decades has been dominated by the use of high pressure sodium (HPS) lamps. Other light source technologies have also been angling for roadway market share. There is a critical need for objective technical information about new types of roadway lighting among transportation agencies. In response, the Transportation Research Board (TRB), part of the National Academies, initiated a project to evaluate new lighting technologies and identify new metrics for comparison. Lighting Research Center (LRC) scientists John Bullough, who served as principal investigator, and Leora Radetsky co-authored the report, entitled "Analysis of New Highway Lighting Technologies." The LRC is part of Rensselaer Polytechnic Institute, the nation’s oldest technological research university. Read more »
