  1. High Power LED Lighting Solutions Welcome to an overview of our company

  2. LEDrite Company • Patented Design & Technologies • High Precision Manufacturer & Assembler

  3. Our Patented Technology Background: Super Micro Computer, Inc. San Jose, California(NASDAQ: SMCI) - 3rd Largest Server Company in the world. Ablecom Corporation - Market leader in OEM server provider. Compuware Technology Inc. - Specialize in ODM server power supply.

  4. Patented Heat Dissipation Design • Why Fin Technology? • Our heat dissipation technology was originally derived from Supermicro’s “sunflower” heat fin design. • Supermicro specializes in computer server technology, which demands extremely stable and cool operation conditions. We adopted this proven method of heat dissipation to LED application, a relatively unheard of concept two years ago. Many of our competitors have been influenced by this concept since then.

  5. Largest Heat Dissipation Surface Area The larger the surface is, the better the heat dissipates Our Product Most Competitors’ • Efficient thermal expansion & heat conduction • The thinnest pure aluminum fins in the market • The aluminum heat sink penetrates to the chipset core . It will transfer heat faster with the help of the large surface area. • Die-cast heat sink design • Inefficient thermal conductivity. Bad heat dissipation Good heat dissipation

  6. Patented Driver and Power Supply • State of art design from Supermicro ,a military grade to ensure the stability and life span of 50,000 to 100,000 hours. • All major components inside the driver are tested under hazardous conditions to ensure the highest performance.

  7. Stable Driver and Power Supply LEDrite LEDrite • Why Our Driver is more Stable ? • - The state of art server technology from Super Micro. • The average output current is 700mA at 60Hz with only 10% variation from the average to give a very stable operation condition. • - Most competitor’s drivers we evaluated. The peak current could be as high as 900mA and as low as 500mA which means the LED electricity will fluctuate either too high or too low. Unstable electricity will be easy to damage the LED lighting system.

  8. Product Comparison – Street Light Our competitor’s LEDrite’s

  9. Product Comparison – T8 Light Our competitor’s LEDrite’s • Die-casting aluminum alloy heat sink leads to a poor thermal conductivity. • Result in a short life span • Proprietary heat fin design with largest surface area to efficiently dissipate heat. • Ensure long life operation.

  10. Accelerated Performance Test (APT) – Beyond LM-79 & LM-80 Requirements Why LM-79 & LM-80 test will not guarantee the long life of LED products ? • They are lab tests,under a controlled environment. • It tells the initial lighting criteria but can not predict the product life. • Many reputable LED street lights have impressive LM-79 & LM-80 reports but failed after one year life application . Why is Accelerated Performance Test (APT) important ? • It evaluates the LED product as an integrated technology -LED chips, heat dissipation, power supply and manufacturing process. • It simulates the real environment conditions. • It can help to predict the product reliability.

  11. Accelerated Performance Test (APT) Procedures • 2. Basic Characteristics: • Power factor, • Power Consumption, • color temperature • Current harmonic distortion 3. Optical Characteristics & luminous efficacy 4. Voltage variations 1. Safety 8. On/Off cycling at 93+/-2% relative humidity 7. Durability test 6. On/Off cycling 5. Temperature cycling 10. Light beam maintenance rate 12. Dust & Water proof 9. Surge protection 11. Electro-magnetic noise 13. Vibration * The test will start over from the step one if the product fails at any step of the test.
