TECHNOLOGY / LED CASE STUDY WEDDING BELLES
Situated on 28 acres of rustic farmland in central New Jersey is a wedding venue called Ashford Estate. The ballroom, reminiscent of a barn with peaked ceilings and dual slopes found in its gambrel-style roof, is lit with 90 luminaires from Ilumi- narc that are strategically built into the alcoves, archways and column bases. They wash the entire space with coloured light while additional pin spots light the tables’ centrepieces and moving head fixtures light the dancefloor and project patterns on the ceiling.
Lighting Designers, James Fennelli and Ray Cerwinski of Fennelli Design Group, an event production company located in Allentown, N.J., specified 33 Ilumipod LOGIC TRI-1, 31 Ilumipod LOGIC TRI-4 and 29 Ilumiline LOGIC 12 wash lights for the ballroom’s interior.
Fennelli flanked each column with Ilumipod LOGIC TRI-1. They are recessed into the base of the columns for uplighting. The flat area directly above the window, which serves as the base of the alcove, features
two Ilumiline LOGIC 12 linear wash lights. The space where the ceiling beams meet the joints of the archways features Ilumipod LOGIC TRI-4 in each corner. The complete left side with all three fixtures makes one channel. Thus the right side comprises another. This facet in the lighting design allows for the same column, alcove and archway to be lit by two different colours at the same time.
“During the reception’s first two hours the ballroom is lit by the same colour through- out,” said Fennelli. “Later on guests experi- ence a big colour change and people are amazed.”
Fennelli was awarded the project after meeting with the estate’s owner, sharing his vision of what lighting can do and shaving a considerable portion off of the overall bud- get by using Iluminarc - and adding twice as many lights to the project in the process. “Lighting makes a big difference,” said Fennelli. “It changes the whole look of the room.”

TUNNEL VISION
The Elbe Tunnel, which connects Germany’s Autobahn 7 on either side of the Elbe River in Hamburg, is 3.2km long and has eight lanes running through four bores. Up to 150,000 vehicles use the tunnel each day. To ease congestion, the tunnel features reversible lanes that switch direction to ac- commodate traffic flow.
For many years, tunnel operators relied on a mechanical system of red-and-white marker beacons to guide drivers to the cor- rect lanes. When traffic conditions changed and the lanes needed to be reversed, main- tenance crews moved the markers by hand. The process was time-consuming and costly, not to mention dangerous. Working with WHO Ingenieurgesellschaft mbH as a subcontractor of SIEMENS AG-Traf- fic Solutions, Hamburg implemented an au- tomated traffic-guidance system based on Echelon’s LonWorks technology - an open, extensible architecture that lets control devices from multiple manufacturers inter- act with each other. The tunnel now guides vehicles using yellow LED lights, similar to those used by aircraft while taxiing to or from airport terminals. LonWorks technol-

ogy gives tunnel operators a safe, efficient way to optimise traffic flow, resulting in fewer slow-downs and, as a result, less air pollution. LonWorks technology also reduced the project’s cabling requirements. As a result, the network had less impact on the existing infrastructure and was less expensive to install.
The new network involves over 650 elec- tronically controlled LED lights leading up to the tunnel. The lights are sunk into the road surface at five-metre intervals and connected by cables 100 to 450 metres long. To ensure safety, the lights must work prop- erly day and night, be visible in all kinds of light conditions, and be able to withstand freezing temperatures, heavy rain, and the extreme vibration of constant traffic. “Our engineers ended up creating custom lights for the project,” says Detlef Thon, a managing partner at WHO. “We used special mechanics, optics, and sealants to ensure the lights would be rugged enough.” The brightness of each LED can be varied according to time of day or weather condi- tions. Since LEDs work more efficiently at
lower temperatures, the system reduces the current following a drop in tempera- ture, thus reducing energy use. To ensure consistency within the lighting network, the system monitors 39 values and operating conditions in each light. Values from nearly 40,000 separate data points are stored in a central database for 60 months, giving tunnel operators plenty of data to draw on when evaluating reliability and efficiency.
