1. High vacuum heat pipe was developed by NASA in order to

SAEBIT’s LED products overcame the limit of previous LED lighting !

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

d tproducts. 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 thethe Power LED to be used at 600~800mA, which maximize the efficiency of Power LED.

3. Those products using higher power LED than 3W produce much higher performance in luminance and light intensity at the givenhigher performance in luminance and light intensity at the given power consumption.

4. Lifetime of LED is guaranteed under optimum conditions which LED makers describe.

TECHNOLOGY INTRODUCTIONTECHNOLOGY INTRODUCTION

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,

(1) High Vacuum TechnologyHigh vacuum technology enables the heat conductor to

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

(2) Heat Sink Technology( ) eat S ec o ogyAluminum heat sink was specially designed to have 12 pins and 39 holes to get the ratio of heat dissipation optimized.

(3) Pi E i T h l(3) Pipe Expansion TechnologyCombining aluminum heat sink and stainless steel heat conductor without any leakage of inner heat transferring medium, the technology of expanding stainless steel pipe from 16mm to 17.5mm diameter in a very short time is yessential. 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.

LED VS METAL HALIDE FOR STREET LIGHTS

• Illumination intensity over the streetMetal 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.arrangement of LED bulbs.

• Sights of driversMetal halide lights often obstruct sights of drivers and some recent products now in the form of l hplane shape. SAEBIT LED light fixtures were originally developed to have plane shaped to secure the sight

of drivers.

• Rated LifeWhile 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

CHARACTERISTICS OF LED LIGHTS

Low power consumptionBasically 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 LifeWhile 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 MaintenanceLumen MaintenanceNormally 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 ColorsLED lights uses RGB(Red, Green, Blue) colors, therefore LED lights can produce all colors that can be made with the g ( , , ) , g pcombination of those.

Eco-friendlyLED 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 COLow power consumption itself is eco-friendly as it reduces the consumption of CO2.

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