Light + Building Post Show Report: The Six Most Noteworthy Observations by LED professional

Light + Building Post Show Report: The Six Most Noteworthy Observations by LED professional In the weeks and months before the show it was obvious that the major topics were going to be IoT and connectivity. There are many reasons for this. One is that LED lighting has become established but the big deals for smart lighting and human centric lighting are missing. IoT seems to be the way to improve communication and enable both smart lighting and HCL. Arno Grabher-Meyer from LED professional gives a summary of his impressions of the fair in regards to these topics, and beyond. Read more »

DoE: Solid-State Lighting R&D Plan

The solid-state lighting (SSL) revolution signals a profound shift in how we will use and consider lighting and represents a huge opportunity to generate significant energy savings. The energy being used for lighting represents a significant portion of global energy use. Rising electricity prices, mounting concerns about climate change, and desire for energy independence are causing the global lighting market to shift toward more energy-efficient light sources.

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 »

DOE Publishes CALiPER Snapshot Report on Indoor LED Luminaires

The U.S. Department of Energy's CALiPER program has released a Snapshot Report on indoor LED luminaires, which utilizes the LED Lighting Facts® program's extensive product database to help industry stakeholders understand the current state and trajectory of the market for that class of products. Based on data through the first quarter of 2014, the report focuses on five types of indoor luminaires: downlights, industrial ambient luminaires (e.g., high-bay and low-bay), track heads, troffers (e.g., 2×4, 2×2, 1×4), and linear fixtures (e.g., linear pendants, strip lights). Together, these five product types represent the bulk of all indoor luminaires listed by LED Lighting Facts, and about one-third of the total products listed. Read more »
