SEOUL, KOREA--(MARKET WIRE)--Mar 7, 2007 -- Seoul Semiconductor (KOSDAQ:046890.KQ - News), the country s leading LED producer and one of the ten largest in the world, released today Acriche 2W single emitter of octagon type, a brighter and new design of the innovative semiconductor lighting source that runs directly from AC power without converters. Acriche 2W single emitter of octagon type has a luminous efficacy of 48 lm/W, which is 20% brighter than the version the company began mass producing last November. This level of brightness is comparable to conventional LEDs which report 57 lm/W but experience a 20% loss in conversion. Seoul Semiconductor plans to increase Acriche s luminous efficacy to 80 lm/W in the fourth quarter of 2007, and to 120 lm/W in 2008.

"Our team of engineers has been working around the clock, and we are very proud that in just three months we have been able to deliver this kind of improvement," said Do Hyung Kim, head of the Acriche unit at Seoul Semiconductor.

Acriche s new packaging as a single emitter with a diameter of 25 mm also enhances its use for various applications. "You can apply second optics (collimators) to Acriche 2W octagon type to adjust for various lighting applications," said Mr. Kim. "For instance, the lens with narrow viewing angles can be used for lighting fixtures that focus on a certain area such as reading lamps, while the lens with wide viewing angles can be used to illuminate a wider space like a living room in a home or an office."

The company is planning to release Acriche single emitter without a PCB soon. "This will broaden the range of application for Acriche even more as our customers will be able to make the PCB type they need and array emitters on the PCB," said Mr. Kim.

Acriche is a more efficient and brighter lighting source. With its new architecture, Acriche reduces electricity costs by 85% compared to incandescent lamps; and by 50% compared to general fluorescent lamps. Its luminous efficacy of 48 lm/W is also higher than halogen at 20 lm/W and incandescent at 15 lm/W. Acriche s ability to focus lighting also makes it more efficient than incandescent and fluorescent which emits 360 degrees of light.

Acriche has been designed for conventional lighting applications including architectural lighting, scenery lighting (such as park lighting), stand lighting, exit lighting, street lamps, industrial lighting and many others.
