Trying to create a light close to sunlight, we have come a long way. Initially, they began experiments with their own two-spectral luminaires (blue and red), but their application did not give the desired result, because, contrary to the existing opinion, plants need the average component of the spectrum, too. The lack of natural light causes various disorders in plants. Plants need sunlight to grow in quantitative and qualitative terms. It is not so much in northern latitudes, and traditional lamps in greenhouses cannot replace it.
Relative spectral efficiency of photosynthesys
Spectrum of agricultural light
As a result of traditional methods of growing plants in greenhouses, we have a high production cost and low organoleptic and chemical indicators of production.
Plants grow, bloom and bear fruit through the process of photosynthesis. Two main components are involved in this process - chlorophyll groups A and B and carotenoids. They perceive the colors of the full spectrum, and not the trimmed area.
Spectrum of 2 LEDs emitting light
Such radiation is easily obtained by mixing the light of 2 LEDs emitting light in two bands with peaks at 460 and 660 nm. but this is not enough. It is the yellow-green part that activates the photoreceptors in the plant, allowing more complete use of the extreme spectral components.
Spectrum of our light
Therefore, we began to conduct experiments on the creation of a full spectrum of RGB LEDs, later, a spectrum of luminaires, was created using 12 groups of monochrome LEDs. The latter option produced more or less acceptable results, but the power consumption began to approach the consumption of electricity by lamps of sodium and mercury lamps, and the cost of such luminaires was quite high, which made their application not cost-effective. Therefore, we have come a long way towards creating polymers that allowed us to lift the middle part of the spectrum without large losses of light flux.
Plants grow during 22 days period in our laboratory without any fertilisers and without acces to natural sun light
Extension of the LED service life
Unique composite thermally conductive materials have been created, which make it possible to remove heat from the heated surface of the LEDs as much as possible, which has a positive effect on its durability. The service life of LEDs, without the degradation of crystals, can be increased from 100,000 hours to 200,000 hours, which corresponds to 22 years of continuous operation.
