Introduction of Groundbreaking Industrial/Home Lighting Product from Korea
Seoul Semiconductor's Acriche Family Exceeds DC LED efficiency
(CEO Chung Hoon Lee, www.acriche.com), a world-leading LED (light-emitting diodes) manufacturer, announced the introduction of the Acriche 4, a breakthrough alternating current LED product, in major markets around the world today.
The A4, which will be mass produced and available this quarter, has a world's best luminous efficiency of 75lm/W, and is capable of replacing warm white incandescent and compact fluorescent light sources in many consumer and commercial applications.
Currently, white LEDs are divided into two major markets: products with a high Color Rendering Index (CRI) greater than 85, which is close to natural light, and products with a normal CRI of 70 to 80. High CRI products will often be significantly less bright than their lower CRI counterparts, but due to their similarity to natural light, high CRI sources are excellent for high quality light applications. LEDs with normal CRI achieve a greater brightness but have the disadvantage of being quite different from natural light.
The new and highly innovative Acriche A4 product, however, achieves both a high CRI and superior brightness. The A4 devices have a color temperature of 3000K and include multiple new technologies that provide excellent efficiency of 75 lumens per watt (lm/W) with a High CRI of 85.
It is the first time that Alternating Current (AC) LEDs have achieved better luminous efficiency than LEDs with Direct Current (DC). Seoul Semiconductor stated that "with the mass production of the Acriche A4 series, we will be able to provide both high quality and normal use markets with light sources that have exceptional performance and lower prices. With the A4 series, we want to spread the name "Acriche" far and wide as the world's best LED brand".
Significant advantages of the Acriche A4 series include:
CRI (Color Rendering Index):
Color Rendering Index (Ra) indicates how much a light resembles a natural light source with the influence of the light on various colors of objects. It is measured in units from 0 to 100, where 100 indicates the most similar to natural light.
