Seoul Semiconductor releases the Acrich2 Linear Module, an AC-power LED solution for fluorescent replacements

Date Announced: 09 Feb 2012 Seoul, South Korea - Seoul Semiconductor, a global LED manufacturer, today announced the release of another AC-powered LED solution in the Acrich2 family. The Acrich2 Linear Module exhibits efficacies, light output levels, and power factors comparable to DC LED solutions while eliminating the AC to DC power supply. The solution is on exhibit at the Strategies in Light conference this week in Santa Clara, California. Compared with the existing linear modules driven by direct current, the main feature of the Acrich2 Linear Module is the removal of AC/DC converter and the consequent optimized form factor. This type of solution increases the reliability by removing many of the components which cause early lifetime failures of other fluorescent replacement solutions. The design also provides more flexibility and space to work inside the fixture since the large ballast (power supply) does not have to be accommodated. AC solutions of the past have required a sacrifice in power line performance such as power factor and total harmonic distortion (THD). Acrich2 solves this issue and provides power factor increases to 97%, power efficiencies up to 90% and THD approaching 10%. In addition, the Acrich2 Linear Module will be available with LM-80 and UL testing data. “Let’s plant two trees.” Sunghun Bae, vice president of Seoul Semiconductor, proposed the use of Acrich lamps. His argument is based upon the adoption of Acrich2 bringing similar effects of planting two trees compared with the use of the LEDs driven by a direct current. “Armed with optimized and simplistic system design,” says Mr. Bae, “the Acrich2 Linear Module is a state-of-the-art product that outperforms existing non-environmentally friendly fluorescent lamps and direct current LED fluorescent lamps.” He added, “With the doubly long life span and lower carbon dioxide emission, customers will be able to actualize eco-friendly lighting while paying lower electricity bills.” The Acrich2 Linear Module comes in 220V, 120V, 100V variants. Starting this month, samples are available from the local sales force, manufacturer representatives, and distributors. Earlier this year, the company announced a family of similar Acrich2 modules targeted at the replacement lamp market which allows easy bulb design of A19, PAR, MR16 and other form factors. Glossary • Acrich2 – The 2nd generation solution of the alternating semiconductor light source that can be directly plugged into home and office AC power developed first globally by Seoul Semiconductor. • Power Factor –The ratio of the real power flowing into the load over the apparent power in the circuit. • Electrolytic capacitor – A type of capacitor that uses an electrolytic, an ionic conducting liquid, as one of its plates, to achieve a larger capacitance per unit volume than other types. About Seoul Semiconductor According to the 2010 LED market reports issued by Strategies Unlimited in the U.S., SEOUL SEMICONDUCTOR is the world’s fourth largest LED supplier, holding more than 10,000 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 Acrich, the world’s first commercially-produced AC LED. At present, it provides high-quality LED products through 40 overseas branches (including three local corporations) and 150 domestic agencies and distributors. As the world’s leading LED maker, Seoul Semiconductor has engaged in various talent nurturing and development activities such as CR activities to attract talented manpower, scholarship program, industry-academia cooperation and educational program.
