Seoul Semiconductor's claims record efficiency of 210lm/W for Acrich MJT 5630 LED package

South Korean LED maker Seoul Semiconductor Co Ltd says that its Acrich MJT 5630D package has achieved record luminous efficiency of 210lm/W for a single LED package, and the package's mass production has begun.

Seoul Semiconductor has provided 5630 LED packages (5.6mm wide x 3.0mm long) for application to the lighting and IT fields. The new MJT 5630D+ LED package's most distinctive characteristic is the upgrade of its luminous efficiency to 210lm/W by using LED chips that incorporate Seoul Semiconductor's multi-junction technology (MJT).

According to the Solid-State-Lighting R&D Plan released in May 2015 by the US Department of Energy (DoE), the LED is likely to comprise 40% of the US lighting market (which includes fluorescent lamps and halogen lamps) by 2020. In addition, it forecasted that by 2030, more than 88% of lighting equipment will be replaced by LEDs.

The plan projects that, to reach its goals, the luminous efficiency of the lighting appliance needs to achieve at least 200lm/W and the luminous efficiency of LED packages needs to be at least 220lm/W. In addition, it suggested a strategy for improving the performance of converters that has lowered the efficiency and life of existing LED lamps and a strategy for extending AC LEDs and high-voltage LEDs as a way to improve the efficiency of LED lighting applications. Seoul Semiconductor says that its Acrich driving technology and Acrich MJT technology are in compliance with the AC and high-voltage technologies described in the report released by the US DOE and are also recognized as the best solution for correcting the current problems of high defect rate and short life of converters. The firm plans to expand Acrich MJT supply.

Seoul Semiconductor's chief technology officer Ki-bum Nam says that the firm aims to further prove its technology by achieving LED package efficiency of 220lm/W (the DOE's target by 2020) within a year.
