Seoul Semiconductor Reports Strong Interest for World's First Semiconductor Lighting for AC Power Outlets

Lawmakers' Call to Ban Incandescents Spurs Demand for Energy Efficient Lighting

SEOUL, KOREA -- (MARKET WIRE) -- February 28, 2007 -- Seoul Semiconductor (KOSDAQ: 046890), the country's leading LED producer, announced today that it has stepped up production of Acriche, the world's only semiconductor lighting source that can be driven directly from a household's AC power outlet. The company expects manufacturers to begin introducing Acriche-powered LED light bulbs for wide commercial and household use as early as this year.

"We have been experiencing strong demand for Acriche, which we began producing in mass quantities last November," said Jung Hoon Lee, CEO of Seoul Semiconductor. "Until Acriche, LED products only worked efficiently with DC power systems like in cars, cells phones and computers. Acriche connects directly into AC outlets, eliminating the need for a DC converter, and enabling LED technology to be expanded to general lighting applications."

Energy efficient lighting technology like Acriche has attracted increased attention as US lawmakers discuss the negative impact of incandescent lighting. On January 30, Assembly member Lloyd Levine of California proposed legislation to ban the sale of incandescent light bulbs in the state by 2012, stating that it "would significantly decrease the electricity the country now uses." This was followed by proposed legislation in Connecticut, introduced by Representatives Jim O'Rourke and Mary Mushinsky, to place inefficient incandescent lamps on a "do not sell list."

The distribution of Acriche in North America will be handled by global electronics distributor Avnet Electronics Marketing and catalogue distributor Mouser. In January, Seoul Semiconductor signed a distribution agreement with LightSpeed, a business unit of Avnet whose team of illumination-focused engineers work closely with customers in the areas of thermal, drive stage and optics design. Seoul Semiconductors signed its agreement with Mouser, a fast-growing distributor well known for its quarterly 1,800-page catalogue of electronics components, last November. These distribution agreements will ensure that Seoul Semiconductor's LED applications are readily available to North American manufacturers.

About Acriche

Acriche offers improved power efficiency compared to incandescent and halogen lamps, and outpaces fluorescent lamps in terms of life span, power usage, and convenience. Acriche lasts 30,000 hours compared to 1,000 hours for incandescent lamps, 3,000 hours for halogen lamps, and 8,000 hours for fluorescent lamps. Using Acriche, a consumer will pay 75% less in electricity costs compared to incandescent lamps; and 40% less compared to general fluorescent lamps. In addition, Acriche does not contain environmentally harmful substances such as mercury, nitrogen or lead like other conventional lights.
