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."



AngelTech Live III: Join us on 12 April 2021!

AngelTech Live III will be broadcast on 12 April 2021, 10am BST, rebroadcast on 14 April (10am CTT) and 16 April (10am PST) and will feature online versions of the market-leading physical events: CS International and PIC International PLUS a brand new Silicon Semiconductor International Track!

Thanks to the great diversity of the semiconductor industry, we are always chasing new markets and developing a range of exciting technologies.

2021 is no different. Over the last few months interest in deep-UV LEDs has rocketed, due to its capability to disinfect and sanitise areas and combat Covid-19. We shall consider a roadmap for this device, along with technologies for boosting its output.

We shall also look at microLEDs, a display with many wonderful attributes, identifying processes for handling the mass transfer of tiny emitters that hold the key to commercialisation of this technology.

We shall also discuss electrification of transportation, underpinned by wide bandgap power electronics and supported by blue lasers that are ideal for processing copper.

Additional areas we will cover include the development of GaN ICs, to improve the reach of power electronics; the great strides that have been made with gallium oxide; and a look at new materials, such as cubic GaN and AlScN.

Having attracted 1500 delegates over the last 2 online summits, the 3rd event promises to be even bigger and better – with 3 interactive sessions over 1 day and will once again prove to be a key event across the semiconductor and photonic integrated circuits calendar.

So make sure you sign up today and discover the latest cutting edge developments across the compound semiconductor and integrated photonics value chain.
