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 station’s creating ecological imbalance……
Automobiles and industrial gases polluting the air with CO2……
The whole world is in crisis and moving towards…
•
Saving of energy
•
Lowering of CO2 content
•
Protection of environment
•
Save EARTH mission…
What is…. The Solution?
• Fewer automobiles…..
• Pollution control…..
• Renewable energy…..
………And
LED
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
•
•
•
•
•
