Good Light is as Important as Good Food and Good Air

Scientific studies make very clear that good light is crucial for our health and well-being. Good light does more than enable us to see. It is the most important “zeitgeber” for our brain and body and synchronizes our internal circadian clock. Why are the scientific findings so often not being applied in practice and must we all spend our lives in biological darkness? Read more »

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.

Tech-Talks BREGENZ - Wilfried Kramb, Interior & Lighting Designer, a∙g Licht

TTB from LpR 75: The value of lighting design and light planning has always been underestimated, despite it becoming more important with the rise of Solid-State-Lighting. This is a fact that the public doesn't realize, even though the industry does. Digitalization, compared with the special properties of LED lighting and the aim of the lighting industry to establish their IoT hubs, is a new challenge. This is even more apparent when trying to integrate light sources directly in building structures. Responsibilities and tasks are no longer clearly separated between the different disciplines of architect, lighting designer, IT planner and electro planner. Guenther Sejkora and Arno Grabher-Meyer talked with Wilfried Kramb, owner and CEO of a·g Licht, about these tendencies and topic. Read more »

Well-Being, Light and Exhibition Lighting

Commentary from LpR 71: Well-being is the state of feeling healthy and happy, a good or satisfactory condition of existence, including the emotional and psychological sphere. In 1810, Goethe published a theory based on a human-based approach, combining visual appearance with harmony, culture, sensations and psychology. His color wheel was entitled "allegorical, symbolic, mystic use of color" and was composed of six hues, i.e. red (the beautiful), orange (the noble), yellow (the good), green (the useful), blue (the common) and violet (the unnecessary). The position on the wheel was harmonically relevant and in particular the colors in opposite position generated a strong psychological contrast and were called "opposite colors". Primary colors were yellow, blue and red, and the opposites were green, violet and orange, respectively. Goethe's wheel and the particular matching of opposites soon became popular and was used by the Impressionism movement, especially by Vincent van Gogh and Claude Monet. In this artistic movement, the special impact given by the combination of opposite colors were deliberately aimed to create special psychological effects and sensations. Read more »

Tech-Talks BREGENZ - Dr. Maja Grubisic, Researcher, Free University Berlin & Leibniz-Institute

Awareness of the ecological impact of technologies is becoming more important since climate change due to industrialization cannot be denied. LED lighting is one of the technologies that is deemed as a contributor in helping to reduce the impact caused by wasted energy. Unfortunately, light pollution, due to inefficient energy usage, is not the only problem. Besides the more recognized pollution from pesticides and chemical pollutants, light pollution also disturbs ecology and wildlife. Dr. Grubisic, Researcher at the Free University Berlin & Leibniz-Institute, has been working on this problem for more than five years now. She has written an article, also in this issue, concerning this. At the LED professional Symposium she was also good enough to grant this interview, providing some background information, explaining why light pollution is such an issue in biology and why this topic should be of concern to all of us.
