OSRAM Opto Semiconductors’ LEDs are in the spotlight again. When the advertising light-boxes in Singapore’s Changi Airport were to switch away from fluorescent T8 tubes under REVOLITE’s energy saving program, OSRAM’s Golden DRAGON Plus LEDs were chosen to be the light source by REVOLITE, the renowned LED back-light application expertise. It was found that over the last five years, after replacing the old tubes and installing REVOLITE’s Dio™ back-lit lightbox system with these LEDs, maintenance costs were reduced by as much as 90%. These environment-friendly light-boxes also brought about 73% energy savings.

The Changi Airport is a busy hub, with over 98 airlines flying to 205 cities around the world. It is currently handling 5,000 arrivals and departures every week and servicing over 37 million passengers a year. The low maintenance requirement of the LED light-boxes is a must for Changi in order to minimize disruption caused to the Airport’s operations.

“REVOLITE has installed and maintained over 200 LED advertising light-boxes in the Airport for over 5 years to date. With OSRAM’s LED technology and our experiences in LED back-light applications, we are able to provide back-light LED modules which can fit into any size configuration, allowing customization of the lighting requirement in a variety of light-box sizes. Furthermore, the thickness of the light-box can be reduced from 30cm to 12cm, which is a lot more aesthetic. We are extremely excited as the great leaps in LED technology in recent years has allowed us to provide an ROI as quick as 1 to 2 years for our clients today,” said Calvin Lim, Director of REVOLITE.

“These advertising light-boxes in Changi Airport, equipped with OSRAM’s Golden DRAGON Plus LEDs, prove that the LEDs have exceptionally good quality, high reliability and superior lighting performance. In addition, the LED’s uniform brightness and colour meet the requirements of the demanding advertising industry,” said Kai-Chong Cheng, Marketing Director of OSRAM Opto Semiconductors Asia Ltd.

The retail digital signage market is growing rapidly as public spaces are dotted with advertising and communication billboards. According to iSuppli, this market will grow at a CAGR of 26.8% by 2013. With low energy consumption and low maintenance, the trend is for LEDs to replace traditional light sources. As such, a much higher growth rate for LED retail signage market is expected.

REVOLITE’s LED back-light application with OSRAM’s Golden DRAGON Plus LEDs proven an energy saving advertising light-box solution.
