Ansan, South Korea, (May 8, 2018) – Seoul Semiconductor, a global innovator of LED products and technology, has demonstrated a 277V AC lighting module using its NanoDriver Series LED driver that complies with the industry standard 4kV surge testing. Prior to this, AC LED modules have been mainly used only in residential lighting applications due to the technology’s limited capability to meet the surge requirements for industrial and commercial applications. This demonstration module proves that it is possible to achieve a 277VAC module with high surge capability using Seoul Semiconductor’s NanoDriver Series LED driver.

Prior to Seoul Semiconductor’s recent product introduction, many LED fixture designers perceived AC LED technology as a low performance, low cost solution, assuming that AC LED technology had compromised performance which restricted its applicability. This demonstration module from Seoul Semiconductor proves that it is possible to get a high efficacy, low flicker solution using AC LED technology.

“This demonstration module proves that AC LED and driver technology can be successfully integrated for industrial and commercial lighting, expanding the market for these smaller, simpler, lower cost fixture designs,” explained Keith Hopwood, executive vice president at Seoul Semiconductor.

“The NanoDriver Series devices are the industry’s smallest 24W LED drivers available, enabling lighting engineers to develop luminaire designs with dramatically reduced size, weight and volume,” explained Hopwood. “Expanding the NanoDriver’s applications to include commercial and residential lighting brings to customers in those markets the benefits of Seoul Semiconductor’s AC LED technology – efficacy, low flicker, simpler topologies, and reduced size.”

The NanoDriver Series LED drivers are ideal for a variety of commercial and industrial applications such as bollards, wall sconces, downlights, and flush-mount fixtures. Their small size enables ultra-thin and novel fixture designs, making conventional lamp replacement possible without the need for a large volume recess for the driver, or a reduction in the light output. The NanoDriver Series LED drivers make it possible to convert many conventional fixture designs to LEDs because the driver’s small size makes it possible to integrate it into the fixture housing.

The NanoDriver Series devices are ideal for luminaire designs up to 3,000 lumens, making possible the integration of the control circuitry with the external converter. This facilitates the capability to add commercial lighting 0-10V controls, motion and daylight sensors, as well as integrating wireless control. The NanoDriver Series devices are small and lightweight enough to make airfreight economical, which reduces lead time and streamlines the supply chain.

The NanoDriver Series LED drivers are available immediately from Seoul Semiconductor. For more information about the 4kV surge design, please visit:
