AC LED modules pass 4-kV surge testing

A 277-V ac lighting module using the NanoDriver Series LED driver complies with industry standard 4-kV 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 277-V ac module with high surge capability using Seoul Semiconductor’s NanoDriver Series LED driver.

“The NanoDriver Series devices are the industry’s smallest 24-W LED drivers available, enabling lighting engineers to develop luminaire designs with dramatically reduced size, weight and volume,” explained Keith Hopwood, executive vice president at Seoul Semiconductor. “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 a candidate 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 candidates 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 0-10-V 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 4-kV surge design, visit: http://seoulsemicon.com/upload/170707_150_lmW_Reference_guide.pdf
