Human Centric Lighting: PI-LED maintains the lead

Lorem ipsum dolor sit amet, consectetur adipisicing elit

From 13 – 18 March 2016, “light + building”, the leading international trade fair for lighting and building services technology, was opening its gates again to visitors in Frankfurt am Main. One topic which cannot be ignored this year is Human Centric Lighting. In Hall 4.2/D51, LUMITECH, as innovation leader in this field, will be demonstrating innovative advancements of its cutting-edge PI-LED technology in the form of a biorhythmic lighting installation created by illumination artist, Friedrich Biedermann.

Simulation of the spectral characteristics and variation of natural light during the course of the day – so-called Human Centric Lighting – is one of the key topics of the lighting industry and of this year’s light + building show. LUMITECH’s PI-LED technology plays a special role among the various solutions and system approaches that will be presented. As the first-ever LED technology for biorhythmic lighting, it has been on the market for almost 10 years now and has proved its reliability and success many times over in various types of luminaire and applications during this time. Thanks to continuous and systematic advancements based in particular on practical experience gained by luminaire manufacturers and users, PI-LED now presents itself as a comprehensive system covering almost all design types and control options.

The main USP of LED technology, especially in comparison with white/white systems, is its ability to unite high-quality tunable white light with RGB colours in one and the same light source. Visitors will be able to experience this technological advantage at the impressive presentation of a light installation by Austrian illumination artist, Friedrich Biedermann. Simulated sunrises and sunsets alternate with motivating midday light and inspiring accent colours, using both automated and manually-controlled sequences.

The technology behind it all is revealed on the PI-LED product wall showing several innovative highlights:

  •  “WALLY” a NeoLink wireless control unit based on ZigBee, and which can be operated using a normal pushbutton/rotary switch;
  •  the compact “PI-LED MINI SPOT SMD” opening up new integration options for spotlights and downlights;
  •  the “PI-LED LINEAR SYSTEM M – ZHAGA” which can be used to connect up to eight linear modules in series without power losses, and
  •  the “PI-LED AREA SYSTEM Pro – ALL IN ONE 9x9” which fits perfectly into any kind of grid ceiling luminaire thanks to its adapted dimensions and integrated LMU.

Stefan Tasch, LUMITECH’s CEO, explains the background to these new PI-LED developments and the return to physical light switches as follows: PI-LEDs have come of age. At present, it is the only holistic system on the market that integrates all components – from individual modules right up to converters – into a high-class Human Centric Lighting solution, while at the same time offering an extensive range of different designs and control options. For us, the main aim in any advancement of our PI-LED technology is to achieve perfect interaction of all system components and to enhance user benefits. For instance, lighting systems that can be controlled from a smart phone or tablet app are an absolute must nowadays, but in everyday use an ordinary light switch simply cannot be replaced. We have therefore extended our portfolio by new, yet familiar components: Our “WALLY” can be used to control all illumination options such as automated daylight variation sequences, changes in colour temperatures and RGB light colours via a wireless signal using a normal rotary pushbutton switch. In this way, we have merged high-tech and familiar operations perfectly.
