Abstract: The application of light-emitting diode (LED) in agriculture and bio-industry has been
concerned
by
all
over
the
world
with
the
development
of
LED
technology.
LED
not
only
has
many advantages, such as small size, longer life, low energy consumption, particular wavelength
and low production of heat, but also can emit the exact spectrum based on the need of plant. LED
can actualize a lot of functions, such as energy-saving, environment-friendly and efficient space
utilization,
which
can
鈥?/p>
t
be
achieved
by
conventional
light
source.
The
application
of
LED
in
agriculture and bio-industry has been reviewed in this paper, which includes the characteristics of
LED
and
the
progress
of
LED
applied
in
plant
cultivation,
tissue
culture,
plant
factory
and
controlled
ecological
life
support
system(CELSS).
Trends
of
LED
applied
in
artificial
lighting,
plant factory, CELSS and combination with new energy are also outlined.
Key words: Artificial lighting, Light-Emitting Diode
