Seoul Semiconductor, Launching New Acrich 2

Seoul Semiconductor, Korean LED packaging company (, announced the launch of its ‘Acrich 2,’ providing long life time, low energy consumption and design convenience. The Acrich 2, introduced in 4W, 8W, 12W and 16W boards, will provide a replacement LED solution to replace not only 40W, 60W and 100W incandescent bulbs, but also MR16 halogen lamps and down lights.

The newly introduced ‘Acrich 2’ provides more than a 90% increase in power efficiency by improving the power factor by up to 97% as compared to Seoul Semiconductor’s predecessor  ‘Acriche’ version, and the THD is lower than 25% to comply with the requirements of different countries, including DOE and others. Through cutting edge IC technology, lighting manufacturers can directly plug Acrich 2-based products into the wall without consideration of electrical conditions.

Conventional LED bulbs use electrolytic condensers resulting in temperatures of over 70℃.  These temperatures shorten product lifetime to less than 10,000 hours. Other well known brand products have power factors in the range of 0.5, resulting in two times less efficiency for the same 100lm/W efficiency at the LED level.

John Bae, Vice President of Seoul Semiconductor, states that “high cost, low efficiency and short lifetime which have been critical problems for conventional LED bulbs, can now be resolved through the Acrich 2.”  He also exclaimed that “Seoul Semiconductor will diligently continue focusing on technology and product development to facilitate customer’s LED product development and provide full support in a variety of applications. Seoul Semiconductor, as a worldwide brand company, is licensing Acrich to world-famous companies and has additional licensing deals under negotiation.” commenting that the company’s mission is to “enrich better life through Acrich”.
