March 6, 2007... Semiconductor Lighting source Running Direct from AC Supplies Without Converters

Seoul, Korea--Seoul Semiconductor, which is no. 1 LED manufacturer in Korea and stands within 10 in the world LED market, released “the Acriche 2W single emitter of octagon type”, a new type of package, of which brightness has improved by 20% than the previous ones in only 3 months after that SSC announced the mass producing availability of Acriche, last November, 2006. Acriche is an innovative semiconductor lighting source, which can be running direct from AC supplies without converters. SSC is planning to improve Acriche’s brightness from current 48 lm/W (It is assumed that this level of brightness is almost same as 57 lm/W, considering the loss by 20% due to conversion of conventional LEDs) up to 80 lm/w in the fourth quarter of 2007, and 120 lm/W in 2008.

Seoul Semiconductor has been devoting all its strength to improving the brightness and package design so that customers can conveniently use more improved products, since last November’s announcement of Acrich’s mass production, economical and environment-friendly semiconductor lighting. In result, in only 3 months, the maximum brightness of Acriche reached 96 lumens for two watts, and the luminous efficacy became 48 lumens per watt, which is more improved by 20% than before. Also, the new package type of “the Acriche 2W octagon type” is a single emitter and its diameter is 25 mm. It was designed to make it easier for customers to apply to various kinds of applications. Do Hyung Kim, a chief of SSC’s Acriche department said “Numerous customers has been requesting us to provide single emitter without PCBs so that they can freely make the PCB type of what they need and array emitters on the PCB. Meeting the customer needs, SSC is planning to sell Acriche single emitter without PCB soon. We first introduce “2W octagon type of single emitter” with PCB.”

“It is easy to apply second optics (collimators) to “Acriche 2W octagon type ”, which adjust the viewing angle of Acriche so that customers can create various moods by applications. For instance, the lens with narrow viewing angles can be used for the lighting fixtures focusing on a certain areas such as reading lamps, while the lens with wide viewing angles for those shining on wider spaces like living rooms at home or offices.
Acriche can be applied to architectural lighting, scenery lighting (such as park lighting), stand lighting, exit lighting, street lamps, industrial lighting, and many others.

Acriche offers improved power efficiency, brightness, and lifespan compared to incandescent and halogen lamps, and outpaces fluorescent lamps in terms of lifespan, power consumption, convenience, and actual lighting fixture efficacy. It is the efficacy when applied to actual lighting fixtures: fluorescent and incandescent lamps loose lots of light on the back side, since they emit light by 360 degree, while Acriche emit only to the downside so it looses less light than other light sources. Therefore Acriche can substitute for conventional light sources like incandescent lamps. 1)
Acriche lasts 35,000 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 approximately 85% less in electricity costs compared to incandescent lamps; and 50% less compared to general fluorescent lamps.
