Light at your fingertips: Biorhythmic lighting control was never so easy

Lorem ipsum dolor sit amet, consectetur adipisicing elit


At this year’s Light & Building, being staged from 30 March – 4 April 2014, LUMITECH is presenting trend-setting complete systems for “Human Centric Lighting” together with BAG electronics: for instance, the world's first human centric lighting system for professional applications and with wireless control via ZigBee. Apart from this, the focus will be on the introduction of the DALI Standard DT8 and on innovative PI-LED technology, which combines a change of colour temperatures along Planck’s curves, thus simulating daylight, with fascinating RGB arrangements, all using one and the same lighting technology.

LUMITECH LED technology has always been fully focussed on the relationship between light and humans: both with regard to the effects of lighting on health and well-being and to ease of installation and operation. This is why LUMITECH will be showing new ideas for entire human centric lighting systems at this year's Light and Building, including PI-LED modules in various designs such as Zhaga Spots, linear and area systems, with combined control of a change of colour temperature along the Planck’s curve and a colour-changing light in one single illumination system, as well as converters, control technology and a wide variety of human/media interfaces (HMIs). All components harmonise perfectly, can be installed and applied flexibly, can be operated intuitively and are of superior quality.


Supreme discipline: lighting control – DALI DT8 and ZigBee

Beyond the applicable industrial standards 1-10V, DALI DT6 and DMX, Human Centric Lighting systems by LUMITECH now also offer two more trend-setting control options: an advanced version of the cable-based DALI standard, upgraded to Device Type 8, and entirely wireless control with Zigbee. Stefan Tasch, CEO of LUMITECH Holding explains the advantages of the new control variants: “The enhancement of control options was the next logical step in further PI-LED development. Ease of integration and intuitive operation are extremely important when it comes to establishing LED-based human centric lighting solutions on the market. This is also demonstrated by the response of luminaire manufacturers. At Light + Building, some well-known companies are already showing systems that integrate PI-LEDs with ZigBee or DALI DT8. Especially the wireless ZigBee radio-control standard is a very promising solution. This system not only permits extremely easy implementation of human centric lighting solutions in new buildings, above all it makes conversion in existing buildings much easier. Introduction of the DT8 Dali standard is also a milestone in the development of biorhythmic lighting solutions, as this makes it even possible to control colour temperatures using complex facility management systems. By the way, both systems are operated using easy-to-understand apps which we specially developed while designing a complete system.”


ZigBee: the world’s first control system for Human Centric Lighting

By making it possible to control the system remotely via ZigBee, LUMITECH has again underpinned its role as technological pioneer in the LED industry. ZigBee was originally developed in 2002 as an additional radio-control standard for industrial applications, smart homes and building control systems and is currently gaining in importance. Many devices and control modules, for example for home and office use, will increasingly integrate ZigBee. LUMITECH is therefore now presenting the first-ever Human Centric Lighting System that can also be controlled via the new radio control standard. By means of the “NeoLink Wall Switch” or the NeoLink App“”, the data required for operating the lighting solution can be transmitted over even greater distances (up to 100m), while the system itself consumes very little energy. This makes installation and application easier than ever, which is of particular benefit to anyone wishing to retrofit or convert their existing lighting system into a modern biorhythmic lighting solution.


DALI DT8: Tunable White in complex building structures

As an alternative to ZigBee, LUMITECH has also introduced the cable-based DALI Standard Device Type 8 for all PI-LED solutions. This allows easy integration of Human Centric Lighting into more complex building management systems. For example “adjustable white light” had not been possible up to now with DALI. This deficit has not been eliminated with DALI DT8. DALI DT8 allows you to select and control all the features of a lighting system such as changing the colour temperature, RGB sequences and dimming; both for the complete system and at specific points. Users have the choice of either a touch panel or a 7” display for operating the system.


Human Centric Lighting: Partnership with a future

In the context of ongoing discourse in the lighting industry, “Human Centric Lighting” returns the focus of the discussion to an as yet underestimated potential: humans and their well-being. The focus is no longer just on lighting and energy-efficiency but also on the effect of light on human fitness and health. The spectral composition, colour temperatures and intensity of the light are modelled on the course of natural daylight and simulate it exactly. The transition from a stimulating light spectrum with a higher fraction of blue to a warm light that helps people to relax is particularly important in sustainably supporting human fitness, well-being and health. LUMITECH and the German electronics specialist BAG electronics started their cooperation on the future-oriented topic of Human Centric Lighting at the beginning of 2014 already – with the aim of developing complete, user-friendly LED lighting systems and assuming a leading role in this new market segment. With the presentation of LUMITECH’s new LED and control technologies at the BAG electronics stand, both companies are now underlining their close partnership-based cooperation.
