ZON LED RETROFITS BILLBOARD LIGHTING TO LED-BASED ILLUMINATION

Bridgelux Arrays Increasing Energy Efficiency And Visibility In Outdoor Lighting Module

Livermore, Calif., March 26, 2012 – Bridgelux, Inc., a leading developer and manufacturer of LED lighting technologies and solutions, announced today that its awarding-winning RS LED arrays have been selected by ZON LED as the LED-based light source for their billboard lighting retrofit solution permitting easy upgrades for the most common billboard lighting fixtures in North America. ZON LED’s proprietary retrofit technology directly benefits outdoor advertising customers by delivering much higher energy efficiency together with higher quantity and quality of light. The LED-based lighting technology produces higher quality 5000K light with higher color rendering making the sign graphics vividly standout with bright, realistic colors, appearing more desirable to the human eye. ZON LED is now retrofitting 6000 metal halide (MH) lighting systems for one of the largest outdoor advertisers in North America, with plans to retrofit another 4000 over the next 3 months with installations in Canada and the United States.

“ZON LED was pleased to work with Bridgelux to engineer a custom lighting retrofit system which resulted in dramatic improvements in illumination, increased light uniformity and color quality throughout the panel,” said Arnold Stoll of ZON LED. “Additionally, due to the use of the LED arrays, ZON’s Light Splitter™ technology and heat management features we achieved better beam control allowing us to tackle the persistent problem of light pollution. We believe that this LED retrofit solution will revolutionize lighting practices across the roadway sign industry.”

Current billboard lighting systems use 1 to 4, 400W lamp fixtures to provide sufficient billboard illumination. ZON LED developed a customized retrofit solution using Bridgelux RS LED arrays that accurately directs the light beam onto the billboard panel dramatically reducing the problem of light pollution caused by traditional MH lighting systems. A conventional billboard lighting system with 2 MH fixtures consumes about 4000 kW per year based on the 12 hour per day seven day per week operation. The ZON LED retrofit module by comparison, consumed only about 1200 kW per year for an annual savings of 72% in energy costs. In addition, the long life of LED-based lighting systems virtually eliminates the need of lighting maintenance.
