LED Grow Light Principle
led grow light , also called LED Grow Light , is one of many plant
species in one lamp . We know that the growth of all plants are
inseparable from sunlight ,
The LED grow light is artificial light source instead of the sun ,
making the normal growth and development of plants .
LED Grow Light Features
As a fourth generation light source , LED has many characteristics
different from other electric light , which makes energy-saving
light source of choice. Applied to the field of plant cultivation
LED also showed the following characteristics: rich wavelength type
, just light and plant morphogenesis synthesis and optical spectral
range consistent ; spectral -width half width , pure monochromatic
light can be obtained in accordance with the needs of complex
spectral combinations ; can concentrate specific wavelengths of
light evenly illuminated crops ; not only can regulate flowering
and seed crops , but also to control plant height and plant
nutrients ; less heating systems , small footprint , can be used
for a combination of multi- dimensional culture system , to achieve
a low heat load miniaturization and production space ; addition, it
is also particularly strong durability reduces operating costs.
Because of these significant features , LED is suitable for a
controlled environment plant cultivation facilities , such as plant
tissue culture, horticulture and nursery and aerospace factory
ecological life support systems.
LED Grow Light plant lights relative has many advantages over
traditional , traditional artificial light sources generate too
much heat, such as the use of LED supplemental lighting and
hydroponic systems , air can be recycled, excessive heat and
moisture can be removed , the power can be is efficiently converted
to photosynthetically active radiation , the final conversion of
plant material . Research shows that : the use of LED lighting, the
growth rate of lettuce , photosynthetic rate have increased by more
than 20 %. Mixed wavelength LED light source can significantly
promote the growth of spinach, radishes and lettuce , improve
morphological indicators ; able to make beet bioaccumulation
largest hair roots beet pigment accumulation of the most
significant and produce the highest sugar and starch accumulation
in the hair roots .
LED Grow Light can affect plant growth cycle , a specific
wavelength LED can affect flowering time of plants, the quality and
duration of flowering . Certain wavelengths of LED can increase the
number of flower buds and flowering plants ; certain wavelengths of
LED can reduce flowering response , regulating the flowering stalk
length and is conducive to the production of cut flowers and
listing . Thus the regulation can be modulated by the LED and the
subsequent growth of flowering plants.
