Well-Being, Light and Exhibition Lighting

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

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.

On Smart Luminaires

On Smart Luminaires In the time up to 2010, conventional luminaires with low or high-pressure discharge lamps with a luminous efficacy of about 80 lm/W were developed. The electrical power was dependent on the electrical power of the lamps built in the luminaire. From 2008 and likely until around 2020, luminaires with phosphorconverted white LEDs with one fixed color temperature, a constant luminous intensity distribution and a maximal luminous efficacy of about 140-160 lm/W are developed with an electrical power between 10 W and 300 W for different applications and dependent on the manufacturer. Therefore, a relative increase in luminous efficacy of 80 -100% in the context of the discussions on “energy efficiency” is being achieved. Read more »

Can You Show Me the Next S-Curve, Please?

Can You Show Me the Next S-Curve, Please? The evolution of technologies is often described using the “S-curve” model. In the early stage, in the first phase of its life cycle, technology is mainly driven by fundamental research. Only a few players are active at that time and innovation steps are quite large. In the second phase, early adopters start to develop products and bring them to market. This phase is characterized by huge investments. In the third phase, more and more players enter the technology field, competition becomes important and development speed of the technology decreases. In the last phase, the technology is mature, (nearly) everybody can use it, there are fewer margins and the technology should be replaced by a new one. Many of the SSL technologies have meanwhile reached maturity. Where are the upcoming technologies, what will be the next S-curve? Looking at technology discussions and lectures at LpS 2017 I tried to find answers to these questions. Read more »
