Redefinition of LED lighting in San Francisco new Bay Bridge

The new bay bridge built in San Francisco city in San Francisco city in the United States, is expected to open before the end of 2013, on Thursday night the new Bay Bridge basking in the radiant light, lighting system installed on the bridge thousands of LED different from any other place. Before the invention of the car, the street lights have made the road safer, the street lamp has a unique lampshade to reduce the light pollution, and the appearance of LED has improved the efficiency. Bleyco, an electrical contractor, is responsible for the lighting of the $7 billion bridge, and Musco, a joint sports lighting manufacturer, has adopted the most advanced system ever.

The idea is to start directional lighting using sophisticated solid white lighting carpet on the bridge lane, eliminate appearance zebra and driver window glare, 2008, when the Bleyco contact Musco when this technology does not yet exist, the solution is unknown. At the end of 2009, there was a feasible plan. But even in 2009, Musco still can not control so much by LED chip, and 25 to 50 Cree XM-L LED lamp test in Iowa on rural roads, although other bridges have also been carried out the transformation of LED lighting system, lighting system, but the bay bridge is very unique, each LED point to different places with different "peaked cap", different lens. The top of the lamp is provided with a plurality of layers of metal plates, and the middle part is provided with nylon to suppress vibration. Not only has the practical design, five angle shape design with seven lamps central tower, each bar on the bridge is to represent the seven pillars of the central tower. The system not only has the advantages of long service life, safety and beauty.

Bridge lighting costs $18 million, within a few years do not have to replace the lights and the closure of the driveway, the cost includes 10 years of components and manual warranty. The remote programming system means that engineers can change the brightness of each luminaire without having to climb up to the installation.

Driving along the westbound carriageway of the bridge, the lamps themselves will barely be found. The lamp is mounted on the opposite 20 meter high pole, so it won't glare from anyone's eyes or on the windshield. The whole road is covered by LED white sheets.

In contrast, the old bay bridge is seen to be heavy in the dark, with only scattered yellow spots on the bridge.
