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 »

An Industry at a Crossroads

An Industry at a Crossroads Commentary from LpR 70: We often hear grumbles about the lighting industry suffering under low margins and high costs. Primarily, this is true for most traditional luminaire manufacturers but not as much for innovative controls and driver manufacturers, and even less so for innovative newcomers who understand the semiconductor business that has taken over a share of the luminaire manufacturers' revenue.

UV-Light for Plant Development

UV-Light for Plant Development Commentary from LpR 68: Since the development of the incandescent lamp, greenhouse farmers have been using electric light sources as a supplement to natural sunlight. Initially, light intensity was the major concern. Later, growers learned to manipulate plant development by altering the power distribution of the light spectrum for added value such as taste and appearance. Read more »

Blue Light Hazard - How Dangerous Is SSL Lighting?

Blue Light Hazard - How Dangerous Is SSL Lighting? Modern Solid State Lighting (SSL) technology has long since found its way into our normal working and living environments. In the early phases, consumers were most concerned with lifetime, pricing and light quality of the new LED-based light sources. Now they have become almost ubiquitous, a focus has been placed on safety. At the recent Light+Building exhibition topics such as photobiological safety and blue light hazard (BLH) were highly ranked among both visitors and exhibitors. Read more »

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 »

Brave New World and the Dualism of Light(ing) The lighting business has been quite predictable over a long period of time. Technical changes were introduced slowly, dominated by a handful of leading companies, and mostly due to new, but not disruptive light sources. The life of engineers was mainly determined by a manageable number of parameters: Lighting requirements, light source parameters, costs, product dimensions, and the odd, required feature.

A Lighting Designers Relativity of Light Performance The LED will always be the superstar of light sources. Their precise and clear lighting possibilities have been targeted by lighting planners and architects for the past ten years. The coming years will see the performance of the LED getting progressively closer to the spectrum of daylight and that will, in turn, generate biologically effective LEDs that are even higher in contrast and promise a new kind of feel-good light.

Lighting Up Smart Cities, Dr. Wu Chou, Huawei Although streetlights have been associated with cities for more than a thousand years, they are rarely considered for functions other than luminary purposes. One of the distinct features of streetlights is their geographic location. In particular, streetlights follow the roads and streets that are the arteries of the city, and at night they outline the city so it can be seen from many miles away. Read more »

Lifetime and Reliability by Günther Sejkora

Lifetime and Reliability by Günther Sejkora Although questions regarding lifetime and reliability of Solid-State-Lighting (SSL) products are essential for customers, knowledge about it is still fragmentary. It was easy to give answers to these questions in the times of conventional lamps (incandescent, fluorescent, high pressure): light output degraded over time and end of life was reached when light output fell below a certain level or when the lamp “burned out”.
