Seoul Semiconductor Launches the World’s Smallest LED Driver Developed for Japan Lighting Market

ANSAN, South Korea–(BUSINESS WIRE)–Seoul Semiconductor, a leading global innovator of LED products and
technology, has developed the industry’s smallest 100V / 24W LED driver
for Japan lighting market. The NanoDriver Series LED drivers employ
Seoul’s patented Acrich technology to produce an ultra-miniature device
to drive LED circuits from 8 – 24W with 100V input designs with low
flicker requirements.

“The NanoDriver Series LED drivers will have an significant impact on
lighting fixture design, enabling the smallest size luminaires while
still delivering high efficacy and low flicker using our patented AC
technology” explained Keith Hopwood, executive vice president at Seoul

“Fixture manufacturers can significantly reduce the size, weight and
volume of their luminaire designs, thus providing their end customers
with a highly efficient, less bulky light fixture”, Hopwood continued.
“The NanoDriver Series’ superior efficacy, low flicker, and small size
is the result of Seoul Semiconductor’s continued research and
development in AC LED technology, which delivers a unique power topology
that results in smaller size, increased efficiency and lower costs”

The NanoDriver Series devices are ideal for applications such as flush
mount, wall sconce, vanity and downlight fixture applications. The
NanoDriver Series overcomes the problem of the limited space in lighting
fixtures for the electronic controls, it had previously been difficult
to convert these applications to LEDs, as there was no space for
conventional driver components and circuitry.

The NanoDriver Series LED drivers are designed for controlling
luminaires up to 3,000 lumens, making possible the integration of the
external converter with the control circuitry. The reduction in size for
control circuits made possible by the NanoDriver Series facilitates
mounting more light sources on the PC board or reducing the overall size
of the fixture and its mounting plate. The NanoDriver Series devices are
also small and lightweight enough to make airfreight practical and
economical, reducing lead times and streamlining the supply chain.

The NanoDriver Series is available in two models rated for output power
of 16W and 24W, for LED assemblies operating at input voltages of 100V
(50 – 60Hz). The drivers have typical efficiencies of 85% and up to
150lm/W fixture efficiency, depending on the LEDs and configuration
used. They feature power factor correction (PFC) of <0.9, with an
over-temperature protection feature that limits the LED current at
temperatures above 160°C. Operating temperature range is -40° to +70°C
(ambient) and -40° to +140°C (case temperature).
