Seoul Semiconductor Has Announced The New MJT 4040 Package

South Korean LED maker Seoul Semiconductor 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 firm also announced that 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, increasing the operating voltage and concentrating more light output within a given area. Operating at a nominal 64V and 20mA, the device can reach output levels of 200 lumens and efficacies as high as 140lm/Watt (5000K CCT).

Streetlights using the MJT 4040 device, combined with the firm's Acrich2 technology, allows operation on AC current without a driver, which usually weighs 2-3kg, and allows Seoul Semiconductor's customers to make light-weight LED streetlights. This allows the end-user to employ the existing streetlight pole infrastructure as well as its functionality (such as existing wiring), drastically reducing retrofitting cost. In additional, due to the reduced component count and the elimination of electrolytic condensers commonly found in traditional ballasts and drivers, reliability is increased, claims the firm.

"The new MJT 4040 extends the Acrich family of LEDs into higher-power applications," says global marketing VP Marten Williams, adding that it is suitable for not only streetlights but also parking-lot lights, security lights, low-bays, high-bays, and 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 firm is accepting high-volume orders.
