The document introduces SAEBIT Tech's LED lighting products and their heat dissipation technology. [1] SAEBIT has developed a high vacuum heat pipe system using NASA technology to efficiently transfer heat away from LEDs. [2] This allows their products to use higher-power LEDs at maximum efficiency while controlling temperatures. [3] As a result, SAEBIT LED lights offer the highest performance in brightness, weight, and price compared to previous products.

4. PERFECT LED LIGHTING WITH POWER LED
SAEBIT’s LED products overcame the limit of previous LED lighting !
1. High vacuum heat pipe was developed by NASA in order to
dissipate high temperature inner heat of spacecraft. It consists of
a sealed pipe made of stainless steel and filled with working fluid.
It can quickly transfer heat from one point to another without
any additional mechanical device. This heat pipe technology
makes our LED products outstanding.
2. Applying this special technology of heat dissipation, the
temperature of heat sink can be controlled not to rise high, so
that Power LED can be used at its highest performance in the
products.
d t
Most previous LED Street Lights using Power LED have been used
at only 200~300mA because they could not properly dissipate
the higher heat generated at the higher electric currents. Saebit
Tech solved this issue with Ultra vacuum technology and enabled
the Power LED to be used at 600 800mA which maximize the
600~800mA,
efficiency of Power LED.
3. Those products using higher power LED than 3W produce much
higher performance in luminance and light intensity at the given
power consumption.
4. Lifetime of LED is guaranteed under optimum conditions which
LED makers describe.

The special technology of heat dissipation with high vacuum heat pipe maximized the light intensity
and brightness of LED lighting. This technology can be separated into Ultra vacuum technology,
Heat sink technology, Pipe expansion technology, Heat pipe technology, Heat pipe working fluid Technology.

High vacuum technology enables the heat conductor to
produce remarkable heat conduction performance by
setting the inside pressure less than 1/1,000mmHg

Combining aluminum heat sink and stainless steel heat
conductor without any leakage of inner heat transferring
medium, the technology of expanding stainless steel pipe
y
from 16mm to 17.5mm diameter in a very short time is
essential. Welding or glue had to be avoided because these
can decrease heat conduction efficiency. The equipment
creating 700 kg/ ㎠ of water pressure for pipe expanding
made this job done.

16. LED VS METAL HALIDE FOR STREET LIGHTS
• Illumination intensity over the street
Metal halide street lights provide good illumination intensity directly under the light, but not in
the area between the lights (approx. 30m).
SAEBIT LED lights provide no dark area over the street by the well planned optimized
arrangement of LED bulbs.
• Sights of drivers
Metal halide lights often obstruct sights of drivers and some recent products now in the form of
plane shape.
l h
SAEBIT LED light fixtures were originally developed to have plane shaped to secure the sight
of drivers.
• Rated Life
While the most efficient pulse-start metal halide lamps are rated for 9,000 hours, LEDs are rated
for more than 50,000~100,000 hours of useful life.
16

17. CHARACTERISTICS OF LED LIGHTS
Low power consumption
Basically LED has no filaments, that results in energy saving up to 60~80%. A 250 watt metal halide fixture would typically be
replaced by a 125 to 150 watt LED fixture.
Long Rated Life
While the most efficient pulse-start metal halide lamps are rated for 9,000 hours, LEDs are rated for more than 50,000~100,000
hours of useful life.
Lumen Maintenance
Normally the light's brightness become worse as time goes on, but there is almost no changes in the LED light's brightness over
time.
For example, at the beginning of a metal halide lamp's operation, it puts out a high quantity of useful light. By the end of its rated
life, the lamp is down to about 60 percent of its original light output.
Not only do LEDs last longer, but at the end of their rated life they are still producing more than 90 percent of their original light
output. In addition to that no filament produces no chance of failure.
Variety of Colors
LED lights uses RGB(Red, Green, Blue) colors, therefore LED lights can produce all colors that can be made with the
g ( , , ) , g p
combination of those.
Eco-friendly
LED fixtures contain no mercury or lead, and are restriction of hazardous substances (RoHS) compliant.
Low power consumption itself is eco-friendly as it reduces the consumption of CO2.

Quick Start/Re-strike Time. Variety of size available for fixtures. Much less cost for maintenance, therefore the longer used, the
