Seoul Semi launches LEDs reaching 140 lumens/Watt

The firm's III-nitride based AC-driven Acrich2 LED modules reach the equivalent luminance efficiency of DC LEDs
Seoul Semiconductor has announced that Acrich2 LED modules powered by AC are now achieving luminous efficacies of 140lm/W, nearly a 20 percent upgrade from previous versions.

The technology has been incorporated into lighting fixtures already being sold in major North American lighting retailers and has become the world’s best luminance efficacy AC LED module in the global solid state lighting market.

The latest product being released is 10W and can achieve 1,400 lumen in cool white and 1,250 lumen in warm white. Accordingly, it achieves the same level of luminance efficacy that DC LED module with 180lm/W LEDs would offer.

This increased efficacy saves an additional 20 percent of power compared to the older versions. In addition, new arrangements of the LEDs on the board optimise the light pattern for specialised solutions such as flush-mount ceiling lights for living rooms, kitchens and porches.

Seoul Semi says its Acrich2 is the world’s first module with an on-board IC and multi-junction technology (MJT) LED that can be directly plugged into the wall without a ballast, driver, or converter.

Newer variations of the Acrich2 family include smart functions such as dimming inputs and surge suppression circuits which create exceptional added value for lighting designers.

Marten Willemsen, Vice President of Marketing for Seoul Semiconductor, says, “Efficiency and design flexibility have been dramatically improved with the latest Acrich2 modules giving 140lm/W.”

He adds, “Acrich2 modules have already been adopted by well-known lighting manufacturers and are selling in major retail stores. We believe the success of the Acrich2 LED modules will increase our market share in both the indoor and outdoor LED lighting markets.”
