LED Basics
2008-10-17 LED – Light Emitting Diode
Semi-conductor illumination is also named solid state lighting or LED lighting. Semi-conductor illuminant as one
of the new solid cold light sources, possesses the obvious advantages of lifetime, energy-saving, environmental-friendly, and substantial improvement in the overall human visual experience . In effect , LEDs have revolutionized
the "world of luminance".
LEDs have several attributes compared to traditional lighting sources
Luminous efficiency：80%-90% efficient light output compared to 10-15% for incandescent and fluorescent lamps.
Light quality ：No infrared or ultraviolet radiation, very little heat produced.
Input power ：Uses between ¼ & 1/10 of power consumed by traditional light sources.
Lifetime：Over 50,000 hours whilst retaining at least 70% average lumen output.
Eco-friendly：LEDs sources are recyclable, with no mercury pollution. |
