Seoul Semi launches linear AC-power LED modules
Seoul Semiconductor is releasing a new AC-powered LED product in its 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,” proposed Sunghun Bae, vice president of Seoul Semiconductor. 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 optimised and simplistic system design,” says 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 actualise eco-friendly lighting while paying lower electricity bills.” The Acrich2 Linear Module comes in 220V, 120V, 100V variants. Samples will be 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.
