TECHNOLOGY / CASE STUDIES LED PIPING


Northern Europe’s largest concert organ is given a fresh look by Martin Professional.


In the autumn of 2010, Denmark’s Aarhus Symphony Orchestra was the proud recipient of a beautiful, new concert organ that now graces the Symphonic Hall of the Concert Hall in Aarhus. The pipe organ is a stunning piece of craftsmanship and was built by one of Europe’s notable organ masters, Orgelbau Klais of Bonn, who have provided pipe organs for famous concert halls all over the world.


The Orchestra naturally wished to highlight the unique instrument and chose to light its façade using an LED colour changing lighting system from Martin Professional. Over 100 metres of Martin LED strips mounted on the back of the wooden slats light the organ pipes (from a distance of only 15cm) while mounted vertically at the bottom of the slats and lighting the lower conical part of the pipes are Martin Tripix 1200 and Tripix 300 LED linear luminaires. “With the help of the Martin lighting, the


organ can stand out visually, depending on the organ’s role in the concert,” Aarhus Symphony Orchestra Music Director Palle Kjeldgaard says. “An organ of this size can play all the notes and the light complements this perfectly. With the possibility to make any shade of colour, we can create an expression that fits the music.” www.martin.com


FLAME EFFECTS


Durability and flexibility were key in the selection of the Griven LEDs that animate Azerbaijan’s newest landmark.


Officially opened at the end of 2011, Baku Flame Fountain has already become a landmark of the Azerbaijani capital. Standing in the middle of a large fountain pool, this triple helix flame sculpture is manufactured in high grade stainless steel. over 1,500 banks of LED lights are fixed directly onto the tower body, concealed behind specially manufactured glass rod cladding rails that produce an even diffusion of the light.


The LED lighting fixtures required for this extraordinary project needed to be highly flexible, modular and fully reliable, being installed onto a 30 metre high structure sited in a harsh weather-beaten location. Moreover, a full digital control over all functions was a vital requirement in order to seamlessly manage the complex lighting scheme of the flame sculpture, which was also required to harmonise with the water


jets choreography of the three surrounding fountains. Griven rose to this challenge, delivering a tailored version of its new Graph-i-Code.


Mounted on large surfaces, this high impact IP65 full colour LED module can be used to screen low resolution video- footage, or display a boundless layout of graphic patterns. 1,572 Graph-i-Code banks were used - a total of 8,688 single pixels corresponding to 26,064 DMX channels. This is managed by a software and hardware lighting control system, made up of 30 DMX Output interface units (AL2026) and a Lighting Media Server (AL2025). Each DMX line has been insulated by 60 DMX insulators (AL2085). Along with the lighting and control system, Griven also delivered a dedicated control board for the management of both electrical connections and lighting effects. www.griven.com
