    Tunable white lighting in the classroom: The new ROI is ROO

    Throughout the past few years, we at LEDs Magazine have seen more solid-state lighting (SSL) product development targeted at educational environments. School officials, especially in the public-school arena, must manage strict budgets and plan strategically to obtain the best return on investment (ROI) possible, so the potential financial implications are important factors — first, the cost of premium equipment and installation, but then balanced against the possible payback due to energy efficiency initiatives and less maintenance. One consideration beyond the established cost reductions of SSL in institutional buildings such as schools is the possible impact of tunable white lighting in the classroom. Naturally, dimmability and other controls features such as granularity of color temperature can be customized to various classroom tasks and increase visual acuity. But what’s becoming even more appealing to educational administrators is the ability to influence less “visible” factors in the classroom, such as mood, behavior, and concentration. Strategies in Light, co-located with The LED Show and Lightspace California, will draw more attention to so-called human-centric lighting applications as this, also known as lighting for health and wellbeing. One such presentation, “Lighting for pupils…Tunable white lighting in the classroom and the new ROI,” by Tricia Foster of Acuity Brands Lighting and Catherine Hollenshead of Estes, McClure & Associates (EMA), will feature a case study on a Texas school district’s first-hand experience using tunable white lighting in several classrooms. Here the speakers give a glimpse into the new classroom experience. They will offer up additional details during SIL on how ROI has evolved into “return on objective” (ROO) in such installations. — Carrie Meadows

    China CDC publishes multilingual epidemic control manuals for COVID-19

    To allow timely sharing with other countries of the most up-to-date COVID-19 control and prevention information, particularly as developing countries often have weaker healthcare systems and resources, a critical multilingual manual has been published in both English and French by the Chinese Center for Disease Control and Prevention. To comprehensively disseminate education on control and prevention of COVID-19 globally, based on the latest authoritative materials from China CDC, the World Health Organization and related periodicals -- with first-hand information from China, China CDC has organized experts and translators to develop the set of color publicity manuals containing FAQs regarding control and prevention of the epidemic(www.chinacdc.cn/en/COVID19). The compilation consists of such chapters as General Questions, Maternal and Child Health, Personal and Other Types of Protection, Diagnosis and Treatment. The manual, in a Q&A format, clarifies principal concerns of the general public in a systematic and focused manner, and has different color sketches tailored to African, ASEAN and South Asian countries, and is applicable for use by medical professionals and the general public alike. It can also be downloaded from the website to be circulated, or printed for distribution by Chinese embassies and consulates abroad, public health institutions of countries in Africa and other continents, foreign counterparts and the general public. At the same time, the manuals can also serve as materials to be used by Chinese experts when they go abroad for exchanges and training programs.

    Hybrid Quantum Dot Light Emitting Electrochemical Cells

    Several new light generation technologies that are overshadowed by LEDs and OLEDs are investigated. Most of these technologies are in a very early stage of research. One such technology, the LEC technology, was presented at LpS 2017. Light emitting electrochemical cells can be compared to OLEDs, but they are based on a much simpler inorganic architecture. The innovation in the presented approach lies in the combination with quantum dots, resulting in a hybrid solution. This novel attempt with all its consequences and future prospects was the reason that the LpS Scientific Award jury voted to bestow the award on Dr. Ekaterina Nannen, Group Leader of the Research Group „Solid State Lighting“ at the Nano-Energie-Technik- Zentrum (NETZ) of the University Duisburg-Essen and her research team, Julia Frohleiks and Svenja Wepfer.
