Date Announced: 21 Mar 2013 The new MJT 4040 package is a high-brightness power LED utilizing Acrich Multi-Junction Technology (MJT) with high-voltage, high efficacy performanceSeoul, South Korea - March 20, 2013 Seoul Semiconductor, a global LED manufacturer (http://www.seoulsemicon.com), has announced the new MJT 4040 package which uses Multi Junction Technology to bring performance and size advantages to the LED outdoor and streetlight markets. The company also announced it recently won a retrofit project for streetlights using this new product in China. The MJT 4040 uses multi-junction technology that allows multiple LED junctions to be combined in a single chip thereby increasing the operating voltage and concentrating more light output within a given area. Operating at a nominal 64 Volts and 20 mA, the device can reach output levels of 200 lumens and efficacies as high as 140 lm/watt (5000K CCT). Streetlights using the MJT 4040 device combined with the companies Acrich2 technology allows operation on AC current without a driver, which usually weighs around 2~3kg, and allows Seoul Semiconductor's customers to make light-weight LED streetlights. This allows the end user to use the existing streetlight pole infrastructure as well as its functionality (such as existing wiring), which reduces the retrofitting cost drastically. Additionally, reliability is increased due to reduced component count and the elimination of electrolytic condensers commonly found in traditional ballasts and drivers. Marten Williams, the global marketing VP at Seoul Semiconductor, stated that the new MJT 4040 extends the Acrich family of LEDs into higher power applications and helps our sales team meet the demands of the $1B LED streetlight market. It is perfect for not only streetlights but parking lot lights, security lights, low-bays, high-bays and many other outdoor lighting fixtures. We are currently supplying this product to streetlight manufacturers in China, South America and other developing countries."The MJT 4040 LED was recently released to mass production and the company is accepting high volume orders.
