Seoul Semi launches new family of mid-power LEDs

The company has introduced the Acrich MJT 2525 series with high lumen density in a small footprint
Seoul Semiconductor has released a new generation of LEDs, the Acrich MJT 2525 series, with lumen density in the mid-power class.

The new mid-power product family series symmetrical package has dimensions of 2.5mm x 2.5mm and wide beam angles making these LEDs ideal for applications that require uniform illumination.

This new package is claimed to optimise light extraction from the package resulting in high luminous efficacies.

The Acrich MJT 2525 series high voltage mid-power package with a typical forward voltage of 22V. At 3000 Kelvin (K) and a CRI of 80 it achieves a brightness of 95 lumens (lm) and an efficacy of 105 lumens per watt (lm/W) at an operating current of 40 milliamps (mA) at 25°C.

With a lumen density of 15lm/mm2 this midpower package is suited to space constrained lighting applications. The wide viewing angle on these LEDs also helps implement the omni-directionality in replacement lamp designs.

The high voltage Acrich MJT 2525 series incorporates the Acrich- Multi-junction Technology with multiple junctions on a single monolithic chip eliminating the usage of multiple wire bonds between several die's to create the high voltage architecture.

This construction is said to improve the reliability of the LED package since it reduces the potential number of failure modes associated with wire bonds within the LED package. The high voltage architecture also enables the use of simpler, more cost-efficient drivers, compared to conventional LEDs.

The improved efficiency of the driver electronics also results in less heat generated and fewer electronic components used in the driver design allowing more space for thermal management within the luminare. 

Seoul Semiconductor Executive Vice President of Lighting sales division, Jay Kim says that, "The new 2525 Series has unparalleled lumen density in the mid-power class of LEDs not only reducing the total system costs for designers but also enabling new possibilities in lighting design. To add to that the MJT 2525 series has higher cost efficiency than most mid-power packages and has already been adopted worldwide in a number of design by key customers".
