A light-emitting diode (LED)
emits light when its semiconductor draws electric
current. The LED converts electric energy
directly into optical energy, responding quickly
and making possible pulsed lighting. The size
of LED' is generally approx. 3 - 5 mm. An
LED light comprises several individual LED,
allowing for more flexibility in the development
of lights with more varied shapes and sizes
than conventional lights. |

Flexibility |
| |
The emitted color (wavelength)
can be selected because each light is a combination
of multiple individual LED, |
|
High Efficiency |
| |
The wavelengths of some LED
are compatible with the absorption peak of
the pigments involved in photosynthesis and
photomorphogenesis. Only necessary light for
those physiological functions can be irradiated. |
|
Low Thermal Irradiation |
| |
LED in the visible light
area contain little heat rays, allowing for
short-distance irradiation. |
|
Pulsed Emission: |
| |
Pulsed emission would elongate
its service life rather than contagiously
emitting. In addition, pulsed irradiation
improves the efficiency of photosynthesis. |
|
Reduced Energy Consumption
and Long Life |
| |
LED substantially reduce
power consumption. Depending on the operating
environment, an LED can provide thousands
of hours of light. |

|
|
|
Since an LED emits light through
a semiconductor device, its life is many times longer
than that of other light sources (however, it can
be affected by the operating environment). Pulsed
emission and heat radiation measures can extend
the life of an LED light. |

|
|
|
LED is developed to emit a specific
color efficiently by adjusting the materials used
in the semiconductor compounds. The wavelength of
an LED is relatively fixed, but not as much as that
of a laser beam. Another distinction, LED in the
visible range contain little heat rays. Therefore,
they radiate almost no heat in the direction of
emission. |
