클리브랜드의 브로드웨이, 플레이하우스스퀘어(Playhouse Square)에는 세계에서 가장 큰 실외 샹들리에가 설치되었다. GE LED 전구는 런던의 타워브릿지, 뉴욕의 자유의 여신상 등의 명소와 브라질월드컵경기장을 밝히고 있다. 이곳에 사용되는 LED 전구는 GE 연구소에서 제작한 것으로 수천시간의 수명, 적은 전력 소모량, 그리고 기존의 전구보다 강력한 내구성을 자랑한다.
Cleveland’s historic Playhouse Square turned on the world’s largest permanent outdoor chandelier on Friday. The 20-foot tall stainless steel light piece shimmers with 4,200 crystal pendants and LEDs fixtures drawing just 1,700 watts (the equivalent of 17 standard 100-watt light bulbs.)
The GE Chandelier, as it is called, was designed by Montreal’s Lumid and uses LEDs and light modules built by GE.
Playhouse Square is America’s largest performing arts district outside New York’s Broadway. Many of the area’s theaters were saved from demolition in the 1970s and the chandelier marks the culmination of the area’s revival.
The chandelier hangs some 44 feet above the street from a special steel frame designed by a roller-coaster company. The structure can support five times the weight of the 8,500-pound fixture.
The builders exposed the chandelier and the crystals to freeze and thaw tests (see GIFs up top and below) because of Ohio’s harsh winters. Rather than using glass, they made the crystals from light acrylic resin, which is “practically indestructible,” says Tom Einhouse, vice president for facilities and capital at PlayhouseSquare.
Dominique Alary, president of Lumid – the Montreal company that built the chandelier, said that the design can handle two inches of ice surrounding the crystals. This extreme icing brings the weight of the fixture to 32,000 pounds.
The LED, or light emitting diode, was invented in GE labs by Nick Holonyak. LEDs can last thousands of hours and use a fraction of the power required by standard light bulbs.
GE LED lights also illuminate London’s Tower Bridge, the Statue of Liberty, famous sports arenas and other venues and landmarks. The Tower Bridge system, for example, can cut the landmark’s energy demands by 40 percent and stay in place for 25 years.
LED fixtures are also getting connected to the Industrial Internet. One such system will soon allow cities to harvest data from street lights, manage maintenance, monitor usage, and identify and eventually anticipate power outages. GE’s next-generation Roadway “intelligent” lighting, for example, will allow communities to remotely adjust their street lighting and alert utilities to power outages.
Cleveland is the birthplace of GE’s lighting business. Last April, the company celebrated a centenary of its Nela Park labs, where GE founder and Ohio native Thomas Edison experimented with early light bulbs.
