- Patented intellectual property produces innovative performance of 140 lm and 120 lm/W at 20mA. - Can be operated from a diverse range of power sources (AC or DC power for home & industry)

Seoul Semiconductor a global leader in LED manufacturing announced the latest extension of its innovative and acclaimed Acriche product family. Unlike other devices in the family, the new DC-driven Acriche will be optimized for DC operation and still be able to operate on AC power like the traditional Acriche products. The company will reach up to 140 lumens and 120 lm/watt when the part is released to mass production in the June time frame. By the end of the year, performance is expected to reach to 170lm and 150lm/W .

The new product is classified as a 1 Watt part but will run on only 20mA DC current at 55V in order to improve overall system efficacy at the fixture level. Higher voltage operation allows the fixture designer to choose more efficient AC to DC power supply options to hold the fixture efficacy higher than could be used for traditional low voltage LEDs. The product can still operate from an AC supply giving the designer flexibility to use the same product in a variety of applications or situations especially in space-conscious applications where a converter may not fit.

In making this new product, Seoul Semiconductor takes advantage of its patented Acriche intellectual proprietary. This particular technology is but one of over 300 patents held by Seoul Semiconductor and its subsidiary Seoul Opto Device in the AC LED marketplace. Optimizing for DC operation makes the array desirable for applications where AC power may not be available such as renewable energy sources like solar power which produces DC current.

About Seoul Semiconductor
According to the 2011 LED market reports issued by IMS Research in the U.K. and Strategies Unlimited in the U.S., SEOUL SEMICONDUCTOR is the world’s fourth largest LED supplier, holding more than 6,000 patents. In particular, it owns a wide range of LED technology and production capacity in areas such as deep UV LEDs and non-polar LEDs, as well as Acriche, the worlds first commercially-produced AC LED. Based in Seoul, South Korea but with a large global presence, the manufacturer builds high-quality LED products and sells them through 40 overseas branches (including three local corporations) and 150 domestic agencies and distributors.
