Acriche LED Achieves Luminous Efficacy of 150 lm/w, Plans Q4 Introduction

Mass Production of 100 lm/W Began In The First Quarter

SEOUL - Seoul Semiconductor, a leading LED manufacturer, today announced that it would begin production in late 2010 on a new lamp capable of 150 lm/w. This astounding efficacy will surpass available DC LEDs.

The company also announced that Acriche has begun mass-production of its patented technology AC-powered lamp, which recently achieved a luminous efficacy of 100 lm/w.

Production of the Acriche LED has become more important since the European Union began enforcing a ban on the sale of incandescent light bulbs of more than 100 watts last September and legislated against the use of existing inefficient electric light bulbs in all countries in the future.

Acriche LEDs are more efficient than halogen lamps, incandescent light bulbs and fluorescent lamps and they are the only light source that can be driven by a common alternating current power source without the need of an AC-DC converter.

Two of the world's three largest lighting companies have already chosen the Acriche 100 lm/w for use in lighting applications. In addition, more than 100 companies are beginning to expand the applications.

"With the results of these developments, Seoul Semiconductor enhances its reputation as an environmentally friendly LED company by speeding up the development of Acriche products with high efficiency and high reliability required in the LED lighting market," said Mr. S.M. Lee, Sr. Vice President of Seoul Semiconductor.

About Acriche

Seoul Semiconductor's main product, Acriche, is an AC-driven semiconductor light source. Since the LED does not require a converter; it is more energy- and cost-efficient than DC LEDs. In addition, Acriche is recognized for its safety, having acquired CE and TÜV certifications as well as UL certification in the United States. Acriche is easy to install and highly configurable for many lighting applications from a single source to a tiled array. In addition, with a life span of more than 35,000 hours, Acriche LEDs outlast other LEDs, which can last less than 20,000 hours.

About Seoul Semiconductor

Seoul Semiconductor is the fourth largest LED company globally, according to IMS Research, a British electronics market research agency. The company, which has a large presence in North America, has more than 5,000 patents and owns internationally recognized technology such as Acriche, developed internally; Deep UV LED; and Non-Polar LEDs. The company runs 33 overseas operations, including three subsidiaries, and 150 worldwide distributor locations.

Seoul Semiconductor will be a major participant at Lightfair in Las Vegas from May 12 to 14. See for more information.
