The new Acriche A7 is smaller and has higher reliability and discharge effects. Acriche is one of Seoul Semiconductor's flagship products. Whether accessing 110V/220V common AC or other high voltage or low voltage power supplies, Acriche can work without any converter. 
The Acriche A7 is a 305lm 3.2W LED chip designed for the current mainstream demand in the LED lighting market. It is particularly worth mentioning that the product is packaged in an ultra-small ceramic circuit (8mm x 8mm x 3.7mm). Compared to other similar LED lighting products, the Acriche A7 has a very low lumen/cost (cost/lm). This product is especially suitable for commercial lighting applications such as downlights, MR16, PAR30 and PAR38 with a service life of up to 40,000 hours without the need for any converters.
At present, DC LED lamps are usually required to add converters worth 3,000-5,000 won. After the DC LED is added to the converter, the power usually loses more than 20%. In addition, due to the life of the converter, the life of a DC LED lamp is usually only about 10,000 hours. However, the LED lighting system designed with the Acriche series does not require any converters, which not only reduces system cost, but also improves system performance and extends product life. 
On February 15, 2011, Seoul Semiconductor, the world's leading LED supplier, announced the launch of an AC LED chip called Acriche A7. Recently, Seoul Semiconductor has launched two new high-brightness white LED products. It is reported that Seoul Semiconductor plans to launch a new product every month in 2011. Samples of the A7 series are available, and volume shipments are expected to begin on February 15 this year.
