PhotoBio
A number of recent studies demonstrated that normal plants could
be grown under Light Emitting Diodes light sources very
efficiently. These Solid state lamps (SSL) are tiny
semiconductor chips that generate light when powered. The elements
that the diode is made from determine the light spectrum it emits,
these solid state devices have been improved over the years and now
have greatly increased light intensity and specific wavelengths.
These developments have resulted in SSL as self contained light
source for plant growth.
Applikon has chosen to develop light panel that are ad-on
modules for our standard stirred tank and single-use bioreactors.
This offer maximum flexibility and offer a very economical set-up
for cultivating photosynthesizing organisms . The volume range
covers 3 liter up to 20 liter autoclavable stirred tank
bioreactors and 10 up to 50 liter single use bioreactors.

Technology
SSL (Solid state lamps) plant light has very unique
characteristics which are useful for plant growth applications. An
important characteristic is the spectral distribution of light in
the wavelengths region of 450-500 NM and 630-700 NM, these
bands are critical for normal plant growth as they fall within the
Photo-synthetically Active Radiation, PAR, (400-700), which plants
primarily use for biological processes and are also favorable for
confined applications such as micro-propagation. Another
useful characteristic is long useful life of about 50,000 hours and
the high-energy conversion efficiency. This results in
substantially cooler systems than other light sources. Systems also
save energy by using less ventilation and cooling needs for growing
plants in culture room. Secondly this provides new opportunities
for enhancing growth of several hard to grow plants or plants that
require a specific range of lightspectrum.

Innovative solid state plant growth illumination with Full
spectrum imitates natural sunlight as closely as possible by
emitting light in every spectral range and having peaks at 470nm
and 630nm, without NDIR and ultraviolet spectrum components.

Features
- Long lifetime (50000 hrs) & good lumen maintenance
- Low voltage operation having more than 90% efficiency with no
EMI radiation.
- Directional light output & Even distribution of light over
the target application area
- Great performance in cold environments
- Environment friendly and Shock / vibration resistant
- Photo-synthetically Active Radiation, PAR, (400-700), and Ideal
for plant growth, to achieve better efficiency in the response of
plants
- Electrically isolated thermal path
- Excellent wavelength stability over time ,consistent,
high-reliability
- Usable wavelength blue (470nm) and red (630nm) for plant
growth
- Fully regulated form 0 to 100% light intensities (0 to 10000
lux) in real time
Science and Facts
Plants do not utilize all ranges of the spectrum equally. During
photosynthesis, pigments like chlorophyll and carotene absorb light
more efficiently at particular wavelengths. Using lights tuned to
these proper wavelengths provides an extremely efficient and
economical method of giving your plants an abundant light source in
its most active range.
Plants can use almost all of the light emitted from these SSL
lamps. This is not the case with metal halide lamps where only
about 10% of the power is used for light generation and about 35%
of the light generated by metal halide lamps is useful for growing
plants. In addition, less than 17% of the light output from metal
halide lamps is produced in the peak wavelength for optimum
absorption by chlorophyll. Other lights, like sodium vapor and
florescent have mixed, and somewhat lower results.
