As a part of this newly conceived metropolitan illumination concept, the Bunyodkor stadium - now the biggest sports facility in Uzbekistan giving home to the local football team - demanded a well-framed lighting plan that would be able to overcome the many structural obstacles this pioneering arena involved.
Supported by 64 columns, the three-dimensional sail-like canopies that embellish the entire exterior perimeter of this bowl-shaped stadium, were identified as a core element and therefore chosen as main lighting attractive of the whole structure. According to the appointed lighting designers, sails and columns had to be enhanced by perfectly even colour shades, smoothly cross-fading in a faultless alternation of soft pastel hues and matching tones.
They also had to stand out from the background walls of the stadium thus offering a further element of optical contrast. Prerequisite for a sustainable perceived layout was the use of cutting edge LED lighting fixtures, dimmable and individually manageable via W-DMX wireless DMX control system. Consequently, the final result had to be reached by a remarkable number of lightweight, compact fittings capable of reproducing dynamic lighting patterns in perfect synchrony and displaying individual or combined colour sequences.
Being able to deliver the specified material in a record time, Griven was chosen as official lighting provider for this challenging project by the installation company winner of the tender, the Uzbek company FV Asia Denkriser. Almost 500 LED lighting fixtures by Griven were installed at the Tashkent stadium in order to achieve the desired result.
Sixty-four units of DUNE MK2 were embedded at the base of each column in order to light them up till the junction point with the protruding canopies. DUNE MK2 is a highly performing LED colour changer specifically designed for exterior recessed applications.
Owing to their three-dimensional shape, the 64 sail-like canopies needed to be lit up by differently located fixtures, in order to reach the required uniformity of tones and light output., ZAPHIR RGBW was successfully employed to enhance this core part of the stadium.
Powershine's RGBW units were distributed all around the top edge of the bowl to illuminate its partial roofing. Sixty-four W-DMX receivers and 4 W-DMX transmitters were specified to obtain an optimal wireless digital control of the whole lighting equipment.
