LG Innotek of Seoul, Korea, announced that the company is beginning to
produce Alternating Current (AC) direct LED lighting packages and modules. On
the surface, these appear to be similar at least in function to the Acrich
modules from another Seoul-based company, Seoul Semiconductor.
The company points out that AC direct LEDs rely on alternating current, the
standard power format for lighting in homes, offices, hospitality, and retail.
Conventional LED lighting uses Direct Current (DC) with Switched Mode Power
Supply (SMPS) units. SMPS units reportedly add cost and complexity to the
The AC direct LED from LG Innotek embeds a micro-drive integrated chip in
the LED that controls the current. The company notes that this allows the LED
solution to occupy a smaller space than conventional LED solutions that require
SMPS units. LG Innotek contends that it can reduce costs by up to 30 percent
compared to conventional DC LED solutions.
LG Innotek is debuting a range of eight products. These products include
five types of AC direct LED packages and three types of lighting modules (a
packaged LED with an integrated circuit board). The company plans to market
three more AC LED modules and two more AC LED packages this year.
AC direct LED packages include the 5250HV(High Voltage), 3030HV and the 5630
HV. The 5630HV operates at about 136lm/W. The company claims that it achieves
the world’s highest efficacy for an AC LED. The company optimized the
3030 HV package for micro bulbs like G9 and G4. The 5630 HV and 5250 HV type
packages have received LM80 certification, the U.S. reliability test standard
for LED lighting.
The AC direct modules are ideal for down lighting. The company’s AC direct
LED modules provide light efficiency of 125lm/W, which the company claims is
the best performance in 23W category. The AC direct modules have a CRI above 80
with an optimized light pattern design for excellent light uniformity. AC
direct modules for down lighting avoid dark spots with a uniform light
distribution from a light source placed in the center. The modules also have
built-in connectors to the power source.
A surge protection circuit is embedded in the AC direct modules for bulbs.
The AC module for bulbs is ideal for lighting applications requiring size
optimization because it does not require auxiliary circuits and has a lower
cost than LED modules that do require one. The company plans to offer a 3030W
HV package optimized for omnidirectional bulbs as well as bulb modules and
surface modules later this year.
