PR Lighting’s new generation LED architectural fixtures have been specified top rovide a colour-changing wash of the new PortCity Shopping Mall fa?ade in thecity of Mariupol (Ukraine).
CORTMILtd., the PR Lighting Ukrainian distributor, was able to meet the client’s lighting requirements. Explained CORTMI marketing manager, Stanislav Serbin, “The initial task was to offer an energy saving architectural lighting system for a certain part of the fa?ade that would provide minimal luminosity of 200 lux. LED-based fixtures were requested from the very beginning to minimize running costs.”
“The choice of the models and optical groups was predetermined by the possible points of installation on the general purpose lighting poles — and in terms of price and features the choice was an obvious one.”
The company therefore specified 12 x PR-8802 and 7 x PR-8800 for the outdoor architectural flood lighting, in addition to which CORTMI also provided indoor effect lighting for the children’s entertainment centre Funtura and bowling centre BomBay.
Housed in cast aluminum, with an IP67 rating, the entire PR Lighting architectural lighting system, used to create exterior colour mixing and colour-change patterns, is managed from Nicolaudie Stick and astronomic time control. The program created includes full colour fades and smooth colour change running from side to side.
The current sequence can be chosen by the local authorized staff at any time while the fixtures themselves have automatic environmental brightness adjustment.
The PR-8800 features 108 3W RGBW LEDs (27 each),linear colour temperature correction and 0-100% linear adjustable dimmer; 0-20fps strobe; field angle of 28° (with optional 26° and 56°) and beam angle of 14°(with optional 8° and 45°), with 16 recallable presets and 16 user memories. The PR-8802 resembles the PR-8800 but has two stacked‘heads,’ — doubling the power rating from a total of 216 3W LEDs, with a lensangle of 14° (field angle 32°).
Installedon nine separate lighting masts, either in pairs or individually, all the fixtures were programmed by CORTMI’s engineers, in accordance with the customer’s wishes.
The trade centre itself occupies a total of 78,800 sq. metres (with the shopping area itself utilising net 52,00 sq. metres of space.) Three zones of the fa?ade are lit – the curved fa?ade (measuring 125m x 14m high) and the right and left sides (which are each 30m wide and 20m high).
The installation was performed by the construction company under CORTMI’s supervision.
