Seoul Semiconductor of Korea has released the Acriche 2W single-emitter octagon-type, a brighter new design of the semiconductor lighting source that runs directly from AC power without converters.

The Acriche 2W single-emitter octagon-type has a luminous efficacy of 48lm/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 57lm/W but experience a 20% loss in conversion. The company plans to increase the product's luminous efficacy to 80lm/W in the fourth quarter of 2007, and to 120lm/W in 2008.

The Acriche's new packaging as a single emitter with a diameter of 25mm 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 Do Hyung Kim, head of the Acriche unit at Seoul Semiconductor. "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 product 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 48lm/W is also higher than halogen at 20lm/W and incandescent at 15lm/W. The product'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 others.
