As the city hosting the 2005 Super Bowl, Jacksonville, Fla., spruced itself up. Part of the city's beautification effort included LED technology.

Light emitting diodes (LEDs) lit Jacksonville's 65-year-old Main Street Bridge, which spans 1,680 feet across the St. Johns River.

“We chose the OptiLED luminaires because they are line voltage and don't need remote power supplies, making the installation more contractor-friendly,” said Robert Daffin, president and CEO for Stone Mountain Lighting Group of Atlanta. “Since the bridge is a vintage structure, we had to be careful with the amount of extraneous hardware that would need to be attached to it. Plus the optics in the lights provided us with the ideal viewing angle and distribution.”

The lamps met additional objectives as well:

  • High brightness
  • Durability to withstand the outdoor elements
  • 85 percent less electricity than conventional lights

OptiLED's Linear Optical Array uses an LPI-tailored optical system for pure color mixing with improved uniformity, which results in higher brightness and sharper images. The lamp's micro-diffuser optic option allows different viewing angles with low loss of light while the UV coated lens covers resist UV damage and scratching. The built-in switched-mode power supply improves data transmission as it avoids the power fluctuations that interfere with data. If one unit goes out, the others in the serial data path will continue to function, making it easier to spot a faulty unit in a long segment.

OptiLED's corporate office is in Irvine, Calif.
