3. 1. Company Introduction
Company Background
Maxlux Co.,Ltd has been a frontier company by introducing the industrial
“Metal Halide Discharge Lamp” for the first time in its industry since its
establishment in 2002. On the basis of its successful introduction of HID
system into automobiles on the same year together with its strong human
resource basement, it has obtained various industrial certificates and patents in
the nation and overseas. Therefore, the fundamental technologies of Maxlus
are widely recognized and accepted worldwide.
Maxlux has become the world top 3 professional HID manufacturer together
with Philips and Osram and it has acquired E-Mark and DOT certificates for
bulbs first among HID Lamp manufacturers in Korea. In addition, Maxlux
possesses the most cutting-edge designing technology for stabilizers through
its own R&D institute. Its year-by-year growth is driven by the development of
LED, the source of light for automobiles and the export of HID manufacturing
facilities and plants in relation to the manufacturing of the industrial HID.
Moreover, to keep up with the worldwide momentum for the energy saving
system and demand for eco friendly lightening devices, it has developed the
most optimized system, QSD(Quick Start Saving Energy Discharge), to satisfy
the economic efficiency for customers and the public interests toward saving
environment trend by developing and introducing new concept high quality
products with the superior quality.
We, Maxlux Co.,Ltd, will contribute to the green environment movement as
best as we can.

Replacing 1st generation light that were weak at light efficiency with high electric
Lamp
power, currently 2nd and 2rd generation lights are widely used. However, these
lights contain serious anti-environment friendly matters such as resource waste
2nd Generation due to low light efficiency and containing heavy metals.
Mercury Lamp, Most recently, due to the policy of decreasing CO2 and energy saving system
Fluorescent Lamp construction by Eco-project, the industries are developing the next generation
light system such as LED and QSD.
Especially, the QSD lamp with the approval and the background of trusting HID
technology, is newly self-developed high static pressure electric discharge lamp.
It has been demanded for both indoor and outdoor due to it’s high efficiency and
energy saving.

Fluorescent Lamp Moreover, QSD lamp has semi permanent stabilizer which allows to replace
lamps easily and maintain the high quality light source. It also produces more
than 120Lumen per 1W light efficiency with energy resource saving. It is
perfectly suitable for the national benefit such as CER Increase.
Also, as QSD light source shows similar light source to the natural light, it
enables the natural environment friendly high quality light to human and

Overall Opinion about QSD
Considering light distribution, street light installation simulation and actual electricity decrease effect, the light that can satisfy public interest, convenience and
economic efficiency is QSD lamp. Also, it can prevent national wealth leakage for technology expenses and main components as QSD is of pure national
development technology. In the future, it is possible to compete with companies such as Phillips or Osram resulting national competition power and support
national benefit improvement.
