Rich document Discomfort Caused by Glare from Luminaires with a Non-Uniform Source Luminance
Glare and the resulting discomfort are a persistent issue in lighting that became even bigger with the introduction with LEDs as a light source. While the UGR method is well established, it is sometimes heavily discussed if it is appropriate for SSL. The limitations of the UGR method need to be understood. Peter Thorns BSc(Hons), CEng, FCIBSE, FSLL, explains these limitations and consequently describes the research and how to apply correction measures.
Rich document chemical/x-pdb Adopting an LED More Suited to Circadian Entrainment
Since the introduction of LED lights, a lot has been said about risks of blue light for ocular health on the one hand, and the opportunity of circadian entrainment, on the other hand. While a controversial discussion on the first topic is ongoing, the second topic is well accepted. To solve both issues, Bill Chan, President of LiteController Inc. proposes the application of 465-470nm pumped phosphor converted white LEDs with a content of 86% - 92% blue-turquoise light and 8% - 14% blue-violet light. In the article he concentrates on the second topic and proves the benefit of regulating the circadian entrainment more efficiently, maintaining a high typical efficacy of 150 lm/W and good color rendering of CRI 80+ ideally supporting the WELL Building Standard.
Rich document Energy Focus Launches Advanced UV-C Disinfection Product Portfolio Offering Airborne and Surface Disinfection Solutions
Energy Focus, a leader in sustainable LED lighting and human-centric lighting ("HCL") technologies, today launches a portfolio of germicidal UV-C Disinfection ("UVCD") products, with advanced, patent-pending technologies designed to destroy 99.9+ percent* of various pathogens, including influenza and coronaviruses such as SARS and SARS-CoV-2, in the air or on surfaces to improve indoor hygiene and sanitation. Three initial products – nUVo™, abUV™, and mUVe™ -- complement each other to meet the needs of air and surface disinfection for commercial, industrial and residential indoor environments. The products are available for pre-order on the Company's e-commerce website, through its internal salesforce and distribution channel partners, and deliveries are expected to start during the first quarter of 2021.
