More Design Capabilities and Less Installation Time with Tridonic’s TALEXXengine DC String

TALEXXengine DC StringTridonic has reached a milestone in lighting design with the introduction of its new DC String LED solution. The new TALEXXengine DC String system supports the trend towards the reduction in overall size size of LED luminaires, to increase design possibilities and make installation easier.

In current LED lighting solutions, each LED light source needs an LED driver which contains an AC/DC converter and a DC/DC component. The AC/DC converter takes up the most space in the LED driver, defining the component's minimum size at the same time and this structure is therefore an obstacle to further reduce LED luminaires and to increasing design freedom.

In Tridonic’s new DC String LED solution, the AC/DC converter, is separated from the conventional LED driver and is installed at a higher-ranking central location, from where it can supply LED light sources with a total output of up to 150W in an energy-efficient way and without taking up space.   If installed downstream, the lighting system works as a low-voltage DC LED system. The individual light sources, or luminaires, are now only equipped with a low-profile, compact DC/DC module, or if the module has already been integrated into the light source, this eliminates the limitations that AC/DC converters have created so far. Luminaire manufacturers have the opportunity of further reducing LED luminaires and developing even smaller lighting solutions, which will blend discreetly into the room and offer impressive high system efficiency.

DALI and emergency lighting components will also be centrally connected to the AC/DC converter, eliminating the need for connecting them to the individual LED light sources. DALI dimming commands are converted to digital power line signals for the DC/DC modules by the DALI converter although the system still remains DALI-compliant, with each light source appearing separately as a standalone address and working in an identical way. That way the lighting system only requires one DALI converter, and emergency lighting components can now also be upgraded from a central location without any additional wiring. The central system gives architects and lighting designers far more flexibility for placing luminaires in a room in an aesthetic way, meeting specific demands, whilst installers also benefit from easy installation at reduced cost, with maintenance decreasing too.

Upgrading existing lighting systems is equally simple, for example upgrading a non-dimmable lighting system to a dimmable lighting solution. It's enough to replace the existing light sources with light sources with a DC/DC module, and to connect a higher-ranking central AC/DC converter, as well as DALI and emergency lighting components, if required.

Zumtobel's Supersystem – a modular, multifunctional LED lighting system offering new angles for lighting design and for the flexibility of placing luminaires in a room – provides an insight into the potential of the new DC String LED lighting solution.
