Case StudyAl Rafaa Wedding Hall Complex Doha _ Qatar

BACKGROUNDRecently built in Doha’s outskirts, Al Rafaa Wedding Hall Complex is a multipurpose structure that young Qatari couples marrying for the first time can use free of charge to celebrate their wedding in a magnificent way.

Boasting a traditional Arabian architectural style enriched by many narrow, arched windows and main entrance porches, the low, squared building of Al Rafaa Wedding Hall Complex consists of five halls that can accommodate up to 500 guests each or a total of 2500, when used as a huge, single hall.

PROJECT REQUIREMENTSThe perimeter walls, partially covered by tridimensional panels decorated with repeating geometric patterns with a strong Arabic characterization, needed to be enlightened by an alternation of warm white parts and soft coloured accents.

Al Rafaa Wedding Hall Complex

LIGHTING CONCEPTAccording to the required lighting design, the exterior illumination of the Wedding Hall Complex was divided into fixed warm white parts, alternating with dynamic colour changing areas. GRIVEN was charged with the illumination in dynamically changing pastel tones of specific parts of the compound.

An alternation of soft pastel shades was delivered to beautifully enhance with a dynamic colour changing effect the arabesque patterned walls, the cornice of the roof and the higher palm trees of the gardens through the usage of a DMX manageable colour changing system.

Soft colours, like light blue, warm white, purple, pink or different shades of green, was required to alternate with a smooth colour transition backlighting the arabesques with a colour that should match the roof and the palms illumination scheme.

PRODUCT INSTALLATIONOwing to the demanding project needs, a custom modular linear PARADE-X bar had to be developed by GRIVEN’s engineers specifically for this project in a record time. Equipped with custom fixing yokes as requested by the project specifications, these modular linear bars fitted with 36 or 18 RGB LEDs in succession and with a specifically developed wall wash optics have been located right inside the decorative boxes in order to enhance their Arabic design from within. These sophisticated patterns result now strikingly enhanced by a retrofitted illumination system, that let them shine as beautiful as ever.

168 units of Dune MC RGBW with narrow optics have been embedded close to every palm tree of the garden in order to light them up with the same colour shade of the walls.

1729 custom modules have been installed either on the roof glass cornice or within these decorative boxes - both at their top and bottom sides - in order to deliver a new colour consistence to the whole compound.

PRODUCT COMPARISONGRIVEN’s engineers had to fulfil the hard task to develop a new product that could comply with the demanding requirements of the project specifications in order to overcome the high quality competitor’s offer. With the help of a newly conceived dedicated elliptical optics, a well diffused and powerful elliptical light output was obtained from a custom version of a Parade X unit, which could reach an improved performance exceeding the competitor’s results.
