LED Technology Shines the Light on Ovarian Cancer Treatment
Scientists estimate that nearly 60% of all cancer patients do not respond effectively to chemotherapy treatments. Even worse – many of those same patients experience toxic and sometimes deadly side effects. Now, a Purdue University scientist and entrepreneur is working to use simple LED light to help determine if certain chemotherapy options will work for specific patients.

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.

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.

LiFi Communication Interview
For over a decade, research in LiFi has been intensified with amazing results. When Musa Unmehopa, an authority in the lighting industry, took on the position of Head of Ecosystems and Strategic Alliances for LiFi at Signify, it was clear that LED professional would have to report what he has to say about the status of LiFi and his future plans. We have known him since he was appointed Secretary General at Zhaga at the beginning of 2014. Since then he was always in charge at Philips Lighting, now Signify, in some capacity, also representing the company in the Connected Lighting Alliance. In addition, his resumé marks him as a specialist in standardization and a technology advisor.
