Osram Opto Semiconductors' Golden Dragon LEDs Produce Fascinating Display Of Colors

u

San Jose, CA - OSRAM Opto Semiconductors' light-emitting diodes (LEDs) now illuminate the façade of the newly remodeled German shopping center, KÖWE. Captivating shoppers with a myriad of harmonized color changing patterns, this unique lightshow is achieved through the use of 2,448 Golden DRAGON LEDs backlighting the glass façade of the entrance and providing all who enter with a warm and intriguing welcome.

"The long life of the LEDs and the resulting low maintenance costs were crucial factors in the decision to use light-emitting diodes in this project," Marco Friedrich, manager of LI-EX, the company responsible for the lighting design and technical implementation of the façade, said. "In addition, we were able to use these LEDs to produce a dynamic color progression across the entire façade," Friedrich added. Friedrich is a certified partner in OSRAM's LED Light for you network – a platform at www.ledlightforyou.com providing information and expertise on the subject of LEDs.

The KÖWE shopping center in Regensburg, Germany was recently modernized. During the course of the renovations, the entrance was updated with a glass façade and an advertising banner was integrated into the upper third of the building's exterior. The top and bottom sides of the banner house 816 RGB modules fitted with a total of 2,448 red, green and blue high-power LEDs from OSRAM Opto Semiconductors.

OSRAM's Golden DRAGONs are positioned to direct light both up and down; parallel to the wall. Special secondary lenses on the LEDs featuring ThinFilm technology and an intelligent color control system ensure a homogeneous and dynamic color progression. This allows individual patterns with over 16 million colors to be projected onto the building's outer surface.

Golden DRAGONs have a life of up to 100,000 hours, are small in size and require minimal energy consumption. In color-change mode, the 2,448 LEDs at the KÖWE façade consume a mere 1,800 watts (W).
