LED LIGHTING - The Trend of Future…. By Quella Way.
By Quella Way
The whole world is in crisis and moving towards…
L E D
consumes only 20~ 30% of incandescent lamps, 50% of halogen lamps.
50000 ~ 100000 hours (10-12 years)
A well managed LED light has less than 5% light decay after thousands of hours operation.
No filament – No Gas - No Mercury - No UV rays - No Pb - No hazardous substance
LED lighting is free from strobe flash lighting that incandescent lamps and other lamps have.
A more vivid color of lighting, giving clearer images than low brightness lamps
Warm white, Cool White, RGB, Ranging from 2700K – 7000K
Wind power, Solar power – 100% Green technology to save earth
Stability in static current driving
Maintenance of brightness at a longer period
Maintaining LED junction temperature at low to increase its lifespan
To be economical in mass application
doesn’t need a short-lifespan fan for extra ventilation
Power supply design:
Auto cut off when lamp gets overheated, Maintains safe temperature range for long life.
Setting a time period for lighting, Saving more energy
with a light sensor ,Dusk-Dawn operation.
Use of superior quality electronic components, ensures lifespan up to 5 years or even longer.
LED Chips and Packages
CREE , SHARP , Nichia, OSRAM, Seoul Semi LEDs are, each LED 1W/3W/4W/ and 8W, 80-100lm/W or 85-110lm/W
LED chips wattages are 0.06W, 100 ~ 110lm/W, Less than 0.3% light decay in 5000 hours
