Description
The light-emitting diode is one of the semiconductor diodes, which can turn electrical energy into
luminous energy and emit visible light in various colors, such as yellow, green, blue, etc, as well
as invisible light, such as infrared and ultraviolet light. Compared with small incandescent bulb
and the neon lamp, light-emitting diodes are specially characterized with low operating voltage
and electric current, high reliability and long performance.
The entry barriers of the light-emitting diode industry from the upstream to the downstream are
cut down gradually. The upstream industry includes mono-crystalline chip and the epitaxial wafer
while the middle stream industry is mainly engaged in chip processing and the downstream
industry handles packaging, testing and application. The upstream and middle stream industries,
most competitive and risky fields on world market, have higher technical contents and require
more investments.. In the industrial chain of light-emitting diode, epitaxial wafer and chip account
for about 70% of profits and the packaging accounts for 10 to 20 percent of profits, with 10 to 20
percent held by application field.
Under international energy crisis and the gradual improvement of the environmental protection
requirements, the semiconductor light-emitting diode lighting, long performance, energy saving,
safe, green and environmental protection, abundant colors and microminiaturization, has been
recognized as the only one manner of energy saving and environmental protection in the world.
The semiconductor lights, adopting light-emitting diode as the new lighting source, only run up
one tenth of the electricity compared with the ordinary white light lamps and the performance can
be postponed ten folds at the same
