PhotoBio Introduction

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.

3 liter photo bioreactor
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.

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.

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.
