Rfsemi (CEO Lee Jin-Hyo), has attended "The 15^th International LED & OLED EXPO 2017" which is being held from June 27^th(Tue) to 29^th(Thu) at hall 3 and 4 of exhibition hall 1, Ilsan KINTEX and introduced LED lighting applied to the AC direct drive device (AC Direct LED IC).

This company is possessing specialized technology in semiconductor class device fields such as ECM (Electret Capacitor Microphone) Chip, TVS (Transient Voltage Suppressor) Diode and AC direct drive device (AC Direct LED IC). In particular, it is developing and producing LED lighting equipment`s for multi-purpose use, applied to AC Direct LED IC.

The LED lighting introduced in this exhibition is able to sufficiently guarantee the LED lifespan (about 50,000 hours) by adopting the AC direct LED IC and has improved the structural weakness that the driving device of the SMPS does not exceed the lifetspan of the LED.

Deputy of general manager Kim Hyun-Jong, of the sales team said, "Although the SMPS is relatively expensive as the circuit is complicated basically, the AC direct drive system developed by our researchers has replaced it with an IC, resulting manufacturing cost reduction as well as low defect rate" and explained, "As these advantages enable miniaturization and weight reduction, it can be applied to various lightings".

Meanwhile, International LED & OLED EXPO 2017 is the largest LED & OLED specialized trade show in Korea with over 350 domestic and foreign companies participating. Also, during the exhibition, `Laser EXPO 2017` and `LED Industry forum 2017`, which invited the leading authorities of LED industries to explore the current status and development direction of LED industry, were held simultaneously.
