Newly, Seoul Semiconductor Co Ltd has announced the release of another AC-powered LED solution in its second-generation Acrich2 family at the Strategies in Light 2012 conference in Santa Clara, CA, USA. The new product features the removal of the AC/DC converter and consequently the optimized form factor. The company claims that this type of solution increases reliability by removing many of the components that cause early lifetime failure of other fluorescent replacement solutions. In particular, 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. In generally, AC solutions have required a sacrifice in power line performance such as power factor and total harmonic distortion (THD). However, Acrich2 solves this issue and provides power factor increases to 97%, power efficiencies up to 90% and THD approaching 10%. It will be available with LM-80 and UL testing data. The module is available in 220V, 120V and 100V variants. Samples are available from the local sales force, manufacturer representatives, and distributors from this month. Source: www.ledinside.com
