A.C. Programme BT's Tower Logo with Olympic Colours for London 2012 Bid

19th January 2005

A.C. Lighting's Special Projects division recently programmed BT's Tower logo with Olympic colours for a London 2012 Olympic Bid event held in the tower on 30 th November last year.

BT is a premier partner of the London 2012 Bid and is playing an integral part in the campaign to promote the Bid to the UK public and International Olympic Committee. As part of this promotion, BT held the exclusive event for special guests in the restaurant on the 35th floor of the BT Tower.

The closing part of the event, which included a screening of the new 'Sport at Heart' film and interviews with Olympic champions James Cracknell and Shirley Robertson, saw the switching on of the BT/London 2012 lights at the top of the tower.

London creative agency Rufus Leonard designed the original BT "connected world" globe logo lighting concept last April and also provided the new Olympic colours scheme. Design and events company Imagination developed and implemented the original design of the lighting system. A key requirement of the system was that it be flexible to the point of a simple re-programme for special events lighting schemes, such as the 2012 Olympic Bid.

A.C. Lighting's Special Projects division had worked with Imagination's architectural lighting design team, on account of their specialist knowledge of exterior colour-changing systems, to supply and programme the lighting and control solution for the building's original logo. The company was approached again to oversee the programming and switch-over to the new light show based around the Olympic flag colours. The temporary show ran in place of BT's own corporate logo lighting from 30th November to New Year's Eve last year, and forms part of the overall preparations for the IOC's visit to London in 2005.

Having recently upgraded the tower lighting system's controller to provide more processing capacity in preparation for a new animated logo sequence, A.C. Project Manager Ceri Barraclough oversaw the installation of the new controller for the Olympic Show lighting.

The lighting system consists of 48 IP65 rated Martin Exterior 200 CMY luminaries controlled by a 1u. high, rack mount Pentium PC networked to an MA Lighting grandMA NSP Node.

The show was programmed by A.C.'s Neil Vann. The first look saw a white crown fade into the five Olympic ring colours (blue, yellow, black, green and red). The colours scrolled together around the crown for two revolutions, giving the appearance that the tower lighting itself was rotating. The colours then faded to static bands of the five colours to represent the united Olympic rings. After holding for four seconds, the colours then rotated once more and returned to white, whereupon the show started again.

A.C. also supplied a light show 'switch-on' button for the ceremony, which was linked through to the lighting control system on the floor above and activated at the end of the ceremony by Olympic Champion James Cracknell.

As the event's media conference was also held inside the tower, A.C. supplied 2 Solar M200 fixtures controlled by an 8 channel Replay unit and buffered by a Chroma-Q® 4Play DMX unit, to serve as floor lighting for the conference. The system was used to signal to the media when the tower lights had been switched on and then followed with a repeating sequence of the 5 Olympic flag colours.
