Definitions

  • the invention which is the subject of our research, is the problem of illumination in the agriculture, more precisely we are talking about the appliance based on the LED-technology, which is utilized for improvement of the Plant-Production in the specially protected environment.
  • the rate of illumination (depending on spectrum radiation emmission, and the most appropriate for vegetables arel500-20001x, for flowers 4000-50001x and laboratory research 20.000-30.000Ix)
  • the chosen width of the spectrum (it is widely acknowledged that the visible sun-light is within the 400-700nm, and for the plant-production the most appropriate segment of the spectrum is red between 640-680nm, and blue-violet segment of the spectrum between 400-450nm respectively.)
  • the regime of illumination must be compatible with the demands of the user and can be continuous and impulsive.
  • LED DRIVER-UNIT controlled by certain appliance suitable for achieving basiclly alternating RGB spectrum,equipped with plate in terms of size and shape adequate for using in green-houses, consisting (the plate) of LED elements and coolers, fixed horizontally and vertically along the mobile prop, conceived with the goal of achieving the best possible conditions to secure intensive and good quality photosynthetic activity with, at the same time significant saves of energy.
  • This invention is based on usage of LED bulbs which means that some important benefits of that technology has been applied.
  • LED emits approximately the same or even more light in comparison to widely known and classic means of illumination.
  • LED light can be directly led towards the certain spot.
  • LED is able to pulsate (so called impulse operating regime)and enables better energy-consuming, approximately 30% and with specific operating regime 10-100 times higher.
  • UV LED elements of precise wave-longitude could be installed.
  • the complete range of UV-A spectrum is primarily positive regarding its influence on the plants.
  • LED elements consist of LED diodes or LED modules characterised by possibility of emitting coloured mono or polychromatic light, with RGB in its basics. It is important to emphasize, that LED bulb according to determined results, is conceived to create possibility of better utilization of artificial illumination, and thanks to precisely specif ⁇ ced photosynthetic parameters and careful planning, it does influence the plants and certain inner mechanisms within the leaves of the plant, and the consequence is positive changes in growth and fruitfulness of the plants.
  • Pathogens-neutralization could be conducted by exposing of the air-mixture for bulb-cooling, to high flux of the emitted light.
  • IR LED elements could be used, reciprocal to sun-irradiation, but with impulses of defined energies, which are corresponding to chemical aspect of the photosynthesis. Selective emission of IR, is performing direct energetic transfer on the plant,almost without any waste. In accordance to neccesities, the regulation of relation among photosynthetic, preventive and termical operating regime is being conducted, in other words the regulation of the presence of the specific spectra.
  • the primal ventilator whose number of rotations is in accordance with the intensity momentarily engaged, so that it is possible to refrigerate the bulb with the optimal quantity of air CO2 and nitrogen compound. Because of the fact that air-mixture within the refrigerating system is streaming directly along the electrical lines, which in turn transmit electro-magnetic energy, and making it fit for assimilation and temperature from -25 to +35 degrees. Also during the absence of illumination, the ventilator is operating with the minimal number of rotations, providing the environment with cool and warm air-mixture,which does not have to originate from the protected area. That operating regime is capable of securing air-circulation, and protection from insects, humidity and alikes.
  • Benefit of this invention is also the well-costructed plate, efficacious in protection from humidity, small in size and easy to operate.
  • the bulb is capable of operating in three separate ways- manually, half- automatically or automatically.
  • This appliance is mobile,light for installation and adequate to meet the plants needs for illumination.
  • control framework 3 is comprised of substructure 9 assigned for creation of determined signals, then substructure 10 for regulation of the parameters of signals: duration of the impulse, relation signal-pause and frequencies, interactive time-positions of impulse for installed colours and substructure 11 for uniform selection and data-entry.
  • Taster 26 assigned for operating-regime choice is capable of taking two positions 1-2 and l"-2", what consequently means that in the position l-2,exists the possibility of choosing only white light of low intensity,for the purpose of creating favourable operating - conditions, within the specially protected environment, while in the position l"-2" an appliance is operating within limits of programmed spectral and impulsive regime.
  • Umnax invention 40-50V
  • the quantity of output-power is depending on number of installed LED elements, which number defines intensity of the emitted light and determines the intensity of the power unit, in other words power- limit (protection of the appliance).
  • LED elements are emitting light of considerable energy, maximums within red and blue segment of the spectrum. For instance, it is possible to use 6-18 LED elements within the bulb, which are connected serially, in order to create one colour of the spectrum, as it is shown on pictures number 2 and 3.
  • the intended spectrum could be created by combination of colours, in other words by combination of spectra, composed of two,three or more different elements. All elements of the same colour-spectrum can work in unity with the simultaneous start of RGB impulse and out of unity, when the beginnings of RGB impulse are different in time. Operating regime is being managed by control framework 3.
  • the spectrum could be created by parameters- entry (using software or manually) and during the process, the intensity of the specific colours-spectra and to them adequate frequencies, are connected interactively within random whole -numbered quantity (for instance, for three elements, colours or spectra, the relation fa:fb:fc is 1:2: 1,1:3:5.4:3:2 etc.).
  • the complete number of installed elements is defining the maximum of illumination-intensity, and it could be increased by putting one or more bulbs on the first one 7, paying attention to intended height. This could be achieved by linking the prop of the second bulb 7 and connector of the first bulb 7.
  • the instrument of connection is juncture 29.
  • Ventilator 5 is preventing the penetration of humidity and insects,generally present in the plastic and green-houses.
  • Maximal output intensity in other words the intensity of the emitted light is limited only by capacity of the power supply unit 4, but it could be increased by parallel connecting of more power supply units 4, if the electrical installations are adequate.
  • Plate 14 of the LED bulb is pear-shaped, or as it could be seen, it bears the form of rounded, regular, multi-lateral prism or cope. That plate is comprised of adequate refrigerating-appliances, made at the same time, of durable plastic or material of the similar kind. Plate 14 is closed, so that to protect LED elements (LE diodes and LED modules) from various mechanical defects.
  • LE diodes do not generate heat in the front area where they emit light (the exception being use of IR LED elements) but in the rear, at the back of the appliance, depending on the characteristics of elements, operating current and regime, there is a need to cool lamps. Temperatures released by conventional lamps are incomparably higher than operating temperatures of LED elements. For example, metal-halogen lamps emit from 200 - 450° C whereas LE diodes, depending on their type, can have a maximum operating temperature of 40 - 50 0 C. The maximum short- time temperature is higher than 100 0 C.
  • cooling of LED elements is performed by the circulation of the air and CO 2 /N mixture through the primary 8 and coaxial pipes in carriers 17 (PE -Al - PE) through which electrical and signal installations go though.
  • This cooling method has been selected for its simultaneous supply of plants with CO 2 and the same is done when there is no need for cooling.
  • the air mixture with CO 2 or N emerges under small pressure (that is regulated by opening the exit valve 28 in the tank 6 or by fan speed 5).
  • the mixture emerges through openings 19 in the lamp 7 near the plants and as the lamp 7 is 1 meter high and CO 2 is heavier than air, a good supply of required CO 2 has been provided. It is necessary to note that if there is a need for an emission of higher intensity light, additional cooling fans of smaller power are built in the lamp.
  • T 25 0 C.
  • substantial quantities of CO are required and its concentration is regulated in the described manner.
  • Temperature protection if needed, can also be achieved automatically with thermosensors connected to the control unit 3 that by reducing the operating current balances parameters and unloads LED elements by lowering their temperature. This, in fact, is the second protection level. This ensures long and safe appliance work
  • Picture 8 shows a lamp with improved characteristics for plant production in the protected environment that uses the same method of control, feeding and air supply for cooling through the primary 8, as well as the lamp 7.
  • the lamp shown in picture 8 is different from the lamp 7 by its design. It has a different housing shape 30 and a built-in cooling deflector 35 that allows a considerably greater stability of desired operating temperature.
