Using its recently introduced NanoDriver Series LED driver, South Korean LED maker Seoul Semiconductor Co Ltd has demonstrated a 277VAC lighting module that complies with the industry-standard 4kV surge testing.

Previously, AC LED modules have mainly been used only in residential lighting applications due to the technology’s limited capability to meet the surge requirements for industrial and commercial applications. The demonstration module proves that it is possible to achieve a 277VAC module with high surge capability using the firm’s NanoDriver Series LED driver.

Seoul Semiconductor says that, prior to its 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. The firm says the demonstration module proves that it is possible to achieve 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,” says executive VP Keith Hopwood.

“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,” claims 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.”

NanoDriver Series LED drivers are suitable for 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, says the firm. 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, adds the firm.

The NanoDriver Series devices are suitable for luminaire designs up to 3000lm, making possible the integration of the control circuitry with the external converter. This allows the addition of commercial lighting 0-10V controls, motion and daylight sensors, as well as the integration of wireless control. The drivers are also small and lightweight enough to make airfreight economical, reducing lead time and streamlining the supply chain.
