LED LIGHTING - The Trend of Future…. By Quella Way
The 21st Century has pushed human beings into energy crisis… Exhaust of petroleum resources…… Mining of natural resources has become threat to environment…… Hydraulic stations creating ecological imbalance…… Automobiles and industrial gases polluting the air with CO 2 …… The whole world is in crisis and moving towards… Saving of energy Lowering of CO 2 content Protection of environment Save EARTH mission…
What is…. The Solution? Fewer automobiles….. Pollution control….. Renewable energy….. ………And L E D
Why LED ? Lower energy consumption consumes only 20~ 30% of incandescent lamps, 50% of halogen lamps. Longer life span 50000 ~ 100000 hours (10-12 years) Lower light decay A well managed LED light has less than 5% light decay after thousands of hours operation. Environmental friendly No filament – No Gas - No Mercury - No UV rays - No Pb - No hazardous substance
Why LED… Eye – protective LED lighting is free from strobe flash lighting that incandescent lamps and other lamps have. High brightness A more vivid color of lighting, giving clearer images than low brightness lamps Wide color Temperatures Warm white, Cool White, RGB, Ranging from 2700K – 7000K Combination with renewable energy Wind power, Solar power – 100% Green technology to save earth
Key Factors of LED Lighting Constant Current Driver Technology Power factor Efficiency Stability in static current driving Light Decay Maintenance of brightness at a longer period Heat Dissipation Maintaining LED junction temperature at low to increase its lifespan Cost To be economical in mass application
Why GPCON LED Street Light? Fixture design Broad area of heat dissipater ensuring excellent heat dissipation, doesnt need a short-lifespan fan for extra ventilation Streamline dissipater, helping air and rain flow. All integrated high pressure CRCA Steel Sheet Body with Powder Coated or Die-cast Aluminum alloy body, fog-free and Tempered glass, Water proof, Anti-electric strike, Firm protection of street lamp up to 20 years. Power supply box separated from LED heat dissipater Easier for installation and maintenance.
Why CESPE LED Street Light… Power supply design: Power factor up to 0.98 Power efficiency up to 85% Constant current driver Wide Voltage range from 85~265V AC Added features: Temperature monitoring: Auto cut off when lamp gets overheated, Maintains safe temperature range for long life. Time control : (Optional). Setting a time period for lighting, Saving more energy Light control : (Optional). with a light sensor,Dusk-Dawn operation. Longer lifespan : Use of superior quality electronic components, ensures lifespan up to 5 years or even longer.
LED Chips and Packages High Power LED chips : CREE, SHARP, Nichia, OSRAM, Seoul Semi LEDs are, each LED 1W/3W/4W/ and 8W, 80- 100lm/W or 85-110lm/W Low Power LED chips : LED chips wattages are 0.06W, 100 ~ 110lm/W, Less than 0.3% light decay in 5000 hours Why CESPE LED Street Light…
