The invention relates to agriculture, particularly to luminaires intended for the cultivation of various plant products, herbs, vegetables or flowers in the home or industrial environment, and can be used in other areas of the economy where individual illumination, such as when breeding different biological creatures.

The known method and device for lighting plants, in which the luminous flux is formed from three spectra - blue (C) in the range of 400-500 nm, red (K) in the range of 600-700 nm and yellow-green (C) in the range of 500-600 nm, in the ratio: /3 (20%±5%)/(40%±5%)/(40%±5%). There is a method of lighting is accomplished using a metal halide lamp (IPF), in a flask which introduce additives halides and other elements such as aluminum, silicon, etc. While the bulb is filled with inert gases with high pressure. See, for example, patent RF №2040828, IPC 01G 9/26 "a device for irradiation of plants", publ. 27.07.1995,, bull. No. 21.

The disadvantages of this method for lighting plants are as follows:

1) Light range picoprojector made in the form of IPF, consists of three broadband spectra and is not optimal photosynthetic activity of plants (PAA). Therefore, the illuminator consumes unnecessary energy on the I generate a light output.

2) In the process of the IPF spectral composition of their unpredictable changes that worsens the conditions of plant growth.

3) Modify the spectral composition of the radiation with the aid of the known lamp is impossible, and in practice crop for cultivation of various plant species, the spectral composition of the illumination, it is desirable to change as they grow and Mature.

The disadvantages of the known devices picoprojector are that:

1) IPF has a high body temperature and under certain conditions can burn plants or to increase the temperature of the greenhouse to an unacceptable level.

2) IPF lamp explosive and can scatter into fragments accidental exposure to spray arising in the process of watering plants.

3) To turn on the lamp requires a special start-control devices (PRA), consisting of an incendiary device and the ballast resistor, which lost part of its power.

4) the lamp does not exceed 5000 hours, which increases operating costs for lighting.

5) the lamp supply Voltage reaching with the inclusion of several kV is dangerous for staff.

There is also known a method for the artificial lighting of plants described in the patent of Russian Federation №2053644, IPC 01G 9/24, 31/02 "Method of artificial irradiation plants in% the CoE growing", publ. 10.02.1996,, bull. No. 4.

In the known method it is proposed to use the sources of optical radiation with minimum variance spectral composition from normative.

The disadvantage of this method is that it generates some averaged spectral composition of light, but you can't regulate it so as to provide the plant with maximum photosynthetic productivity in accordance with the specific characteristics and stage of plant ontogenesis.

Closer and adopted for the prototype is the method and apparatus of artificial plant lighting using led picoprojector depending on the intensity and spectral composition of the ambient light according to the mode of exposure (see, for example, patent RF №2278408, IPC G05D 25/00 "Universal polychromatic irradiation", publ. 20.06.2006,, bull. No. 17).

There is a method allows a wide range to create modes of illumination in accordance with the type of plants, similar to any time of the year, and provides a simulation of illumination of any zone of the globe. It can also be used to simulate different weather conditions, light conditions, for example, "sun", "mostly cloudy", etc. it has a sensor scan of the spectral composition of the optical range of the irradiation and corrector is done on the basis of the feedback of the resulting spectral composition by connecting the respective groups of LEDs.

The disadvantage of this method is that if the coverage does not include the stages of plant ontogenesis. In addition, the method is not possible pulse enable picoprojector adjustable exposure time and duration of the dark pauses.

The drawback of the known picoprojector is that its body has a complex structure, and when exposed to moisture entering the housing, for example, from above, the floodlight can be damaged. In addition, a part of the light is lost due to the fact that the case itself is known picoprojector prevents the passage of light flux going to the lighted object from an external light source.

Currently, agriculture is becoming increasingly widespread greenhouse cultivation of various plant products. In greenhouses it is possible to provide the most favorable for plant conditions for growth and maturation. Productivity space is many times greater than in the cultivation of the same plants in the open ground. To grow plants in greenhouses with artificial lighting all year round.

In the flowering period can be productive adding yellow or orange light. At the stage of fruiting and ripening for some plant species, the role of, for example, green light (cucumbers, tomatoes). Studies on the effect of the spectral composition of radiation of different plant species continue, but currently the results of these studies can be accepted for practical use.

The purpose of this invention is to improve the efficiency of the light flux by providing a more complete process of photosynthesis in plants and the best use of light coming from an external light source with the adult stage of development and species of plants and allow you to change the composition of radiation and to generate bright light pulses of a certain length with the regulation of the duration of the dark pauses.

Simultaneously solves the problem of reducing energy consumption, improving germination and reduced growing period plant products, and to increase its nutritional and taste qualities, improve appearance by providing a more rational use of the light flux, the selection of the optimum spectrum lighting and ignition mode light sources.

The objective is achieved due to the fact that in the known method of artificial lighting of plants in accordance with the specified mode and their specific features using led picoprojector by controlling the spectral composition depending on the magnitude and spectral composition of the ambient light according to the invention set mode lighting control based on the intensity of photosynthesis and in accordance with the stage of plant ontogenesis.

In the embodiment, the technical solution set mode, the lighting is controlled by the pulse enable light elements, altering the time of exposure and the duration of the dark pauses.

Control set mode of illumination on the basis of data on the rate of photosynthesis in accordance with the specific characteristics and stage of ontogenesis plants will allow to intensify the process of growing vegetable products, improve its taste and nutritional t the VA and to improve appearance.

The Central axis of the light flux of the LEDs 3 is directed in the same direction to the front surface of the ceiling 5 and perpendicular to the plane of the housing. The number of LEDs on the boards depends on the power of LEDs, the required total quantity of the light flux and spectrum of radiation. The LEDs 3 are divided into groups with different emission spectrum. The emission spectrum of the LEDs 3 is selected in such a way that its composition corresponded to the needs of the plants of one kind or another for optimum photosynthesis. For example, many varieties of plants, this spectrum consists of red (K) with a range of 660-680 nm, blue (C) with a range of 430-450 nm and blue-violet (f) with a range of 450-480 nm. The ratio of the light flux is chosen in advance and then can be adjusted within wide limits, for example To/f/S from 1/0,3/0,3 to 1/1/1. This ratio is adjusted according to the type and stage of development of the illuminated object research, shifting, for example, aside from the red spectrum at the beginning of growth to blue-violet during maturation.

The ceiling with the end surfaces of the sealed side plates (not shown). Wires (not shown) are located inside the ceiling at the top of their field on the boards 4 or part of the boards. All the shades have a lead wire (not shown)running from one end side of the ceiling. These wires are on the edge of the inside of a U-shaped channel of the housing 1 and is output to the power supply unit (not shown).

In the embodiment, the technical solution Board 4, on which the LEDs 3, made of a transparent material.

In the embodiment, the technical solution of the frame is provided with a transparent top cover 10 (Fig). In the center of the cover top mounted fan 11 with the pipes 12 and slotted cavity 13. The nozzles 12 direct the air flow from the fan under the cover 10 along the ceiling 5. Some of the air flow blows the Central part of the ceiling through the slit cavity 13. When this ceiling 5 are located mainly along the long side of the frame.

In the embodiment, the technical solution of the fan 11 is mounted on frame 1 (Fig.9). Air flow fan 11 is held inside the ceiling 5 (Fig.9) through the nozzles 14. While the shades are also located mainly along the long side of the frame. The flow of air from the fan 11 can go from the center to the ends of the pipes. For this purpose in the Central parts of the ceiling made the CTE is participation (not shown), associated with fan with fittings 14. With face sides of the shades are open. Possible that the fan is operating in the suction mode. In this case, the open end edges of the ceiling is equipped with fencing nets (not shown).

The electrical circuit connections of LEDs consists of a power supply unit 15 (figure 10) and microprocessor control systems, embedded computer block job mode enable (BSRV) 16. BSRV has several independent channels. In turn, the LEDs are divided into groups with different emission spectrum, and each group is connected to a separate channel BSRV.

Groups contain, for example, blue 3withred 3toyellow 3Worange 3aboutgreen (not labeled), etc. as well as ultraviolet and infrared radiation spectra 3tou. In each group of LEDs connected in a series-parallel circuit. Each group of LEDs has an individual current regulator and switch, respectively, 17, 18, 19, 20, 21, etc. located on the panel (not labeled) BSRV.

To BSRV connected programmable controller (RA) 22 for translation scheme from manual mode to automatic, the ambient light sensor (DVO) 23, the spectrometer 24, a timer 25, and a programmable controller species (PTS) 26 display. This is t controller affects BSRV 16, has a set of symbols indicating the type of plants, and provides coverage with regard to this species (tropical and subtropical, semi-arid, sun-loving and so on). To the programmable controller 26 PTS given a few applications with stacks of protocols. In applications there is a more detailed list of plant species (parsley, dill, onion and so on) indicating the algorithm enable LEDs depending on the stage of plant development. Lighting programme detailed on time, for example, germination, emergence of sprouts, rising stem, the emergence of inflorescence, flowering, etc. and can be performed with any stage of plant development since the beginning of the lighting procedure. In addition, the control system introduced programmable controller set modes 27 (PZR), consisting of a set of touch buttons with indication. This controller is required to switch on the automatic mode to maintain the daily cycle of change of the spectrum of light and amount of light in accordance with the selected program, such as time on and off the state system.

The circuit can be entered programmable controller (PC) 28, which represents a set of touch buttons with type pointer to an external source of light (LT, FL, IPF etc). The PC controller 28 also affects BSRV 16. In the food chain has about the speaker switch 29.

In the embodiment, the technical solution in the control scheme introduced programmable controller (IRP) 30 providing a given pulse mode enable light elements with a controller 31, a managing duration light pulses, with the regulator 31' light and the controller 32 of the duration of the dark pauses.

Led picoprojector operates as follows.

In the wiring diagram (figure 10) unit 15 converts the AC voltage into a DC voltage required to power the LEDs 3, and provides stabilization of the current flowing through the diodes.

Depending on conditions and availability of these accessories picoprojector can work both in manual and in automatic mode. To obtain the manual mode requires the RA controller 22 (figure 10) set to the appropriate position. In this case the consumer, using the switches and controls 17, 18, 19, 20, 21, etc. forms the amount of light a particular spectral composition of radiation. Lighting time and the duration of the dark period is provided by the inclusion of a General switch 29.

Picoprojector can work both individually and in conjunction with other types of lighting devices. Programmable controller PC 28 is used when no system spectrometer 24. In this case, set the source type of external lighting (FL, LN, IPF etc) and clicking the appropriate button, you can add to the light flux of the external light source the missing spectral component required for optimal lighting of this type of plant.

For forming the automatic mode, it is necessary to switch RA 22. The controller set modes PZR 27 on the sensor signals, Feb 23 and timer 25 and on the basis of its program changes the value of the current in the LEDs as long as the illumination of an object will not be at the specified level. The program will form a set of commands that affect BWSR 16. Additive dosage of ultraviolet radiation with the spectrum in the range of 320-340 nm and below and infrared range above 800 nm from the LEDs 3touwill eliminate the deficit of this type of exposure and contribute to the suppression of harmful microorganisms.

If the user produces a certain type of plant, picoprojector will provide automatic lighting taking into account the spectral composition of the light flux with respect to danneau. Quite a programmable controller 26 PTS set in the desired position and enter the appropriate program. This process also involved, Feb 23, spectrometer 24 and the timer 25. Picoprojector automatically adds one or the other costal the expansion of the spectrum, which is necessary for the best growth of any species of plants, promotes the accumulation of plant proteins, starches and vitamins, helps to slow down or speed up ripening. It may be necessary to get ready for consumption or sale of plant products to a specific date.

Selected the program will automatically optimize the lighting required at different stages of plant development. This will significantly decrease the integral power consumption.

In many greenhouses roof is made of transparent material that can be used for plant lighting external, natural light source. In addition, for General lighting is often used and also high-intensity light sources (vis). Generally, as the vis used doorsnede sodium lamps or IPF. It is not excluded the possibility of using LL or LN. The case of the proposed picoprojector transparent and allows you to skip through the external luminous flux with little absorption, which contributes to a better illumination of the plants and reduce the total energy consumption of the greenhouse.

Each light source is characterized by a certain range of radiation, which, as practice shows crop, sometimes poorly perceived by plants. The process of photosynthesis and other biological processes, which stems in plants, selective to different wavelengths of radiation. The spectrometer 24, scanning the spectral composition of the optical radiation band, will automate the process of correction spectrum lighting picoprojector considering the source of external lighting. The system gives the possibility to adjust the total spectrum lighting, complementing the total spectrum with regard to HEADLAMP plants and reducing energy consumption.

The proposed device allows the pulsed light from light sources that are provided through the inclusion of BEERS 30. With it you can control the duration of light pulses in a wide range and to adjust the duration of the dark pauses, i.e. to change the off time of the LEDs. The plants receive portions of the light flux with certain selected spectral composition and amplitude, which excite in plants photoactive molecules that form the process of photosynthesis. Is an anabolic process that causes the growth of plants with oxygen. During the dark breaks is the biological activities of plants with carbon dioxide. This process to some extent can be compared with the respiration of living organisms. In practice, the integration mode is determined empirically and is fixed in the program 25 BEERS and BSRV 11. Optim the AUX mode led light will accelerate the growth of plants. Growing plants in flash mode light can be produced around the clock, and the power consumption is reduced in hundreds of times.

The different configurations of the LEDs 3 (3, 4, 5, 6 and 7), the configuration of the heat sinks is determined by the power of lighting devices, the degree of heat dissipation, the presence of elemental basis, ambient temperature, etc. These options extend the capabilities of both consumer and designer to cover all possible applications of the proposed device.

Currently the lighting industry produces LEDs, the spectral composition of which covers almost the entire visible spectrum (red, orange, yellow, green, blue, Indigo, violet)that allows you to create any set light range from full solar spectrum to color. In addition, existing light sources LEDs allow you to get the pulse mode enable with virtually any frequency. Use as light sources LEDs reduce energy consumption, multiple increase of the service life of the system as a whole. They have a low heating body with a temperature not exceeding 45°C, high mechanical strength. The life of modern LEDs reaches 100 you the ball hours (11 years) of continuous illumination. In addition, LEDs have a small size and weight and have a higher light yield per unit of luminous surface than, for example, LN. Plants with light from picoprojector will not suffer from overheating. The minimum time included the status of the LEDs is measured in microseconds.

The arrangement of LEDs in the ceiling will provide them with protection against hit of moisture on them. The presence of the water-repellent plate made of thermally conductive material, prevents the ingress of moisture on the front surface of the ceiling and contributes additional heat.

The luminous flux of LEDs has a one-way distribution in a solid angle. Therefore, picoprojector needs no reflector. The spotlight can be positioned at any height at an angle to the illuminated surface, and the desired maximum illumination produced by pre-selecting LEDs with an appropriate angle distribution of the light flow.

The presence of the fan 11 mounted on the top cover 10 of the frame 1, the guide air flow under the cover along the ceiling (Fig)allows you to install more powerful LEDs needing immediate heat sink.

The use of forced ventilation of internal cavities ceiling 5 (Fig.9) limits the power of applied LEDs only the envelope is time sizes picoprojector.

The construction of the claimed picoprojector is very simple, is easy, relatively cheap materials. It is easy to assemble and designed for repeated long-term use.

Thus, the proposed picoprojector this unique and versatile tool, able to generate an optimal ALIGNMENT. For the consumer it is a complex lighting system for plants with ample opportunities for the cultivation of various plant agricultural products around the clock and at any time of the year.

It should be noted that many questions photosynthesis of plants not yet fully studied. This picoprojector allows you to experiment with lighting. Accumulated with its statistical data can be the basis for adjustments to the program in the programmable controllers PTS 26 and 30 BEERS. Thus, you can easily change the ratio of the light fluxes of the emission spectrum, and duration of exposure of one or another component of the spectrum, and the amount of light.

High functional properties, and a variety of design solutions before the consumer opens wide possibilities for the use of the proposed led emitter and for cultivation of different kinds of living creatures. So, based on it you can, for example, to grow m ladniak birds, to breed rabbits and breed insects or bacteria colonies that are required for different kinds of scientific research.

SUBSTANCE: invention relates to the field of lighting technology and may be used to grow crops under artificial lighting. In method intensities of light flow and spectral composition of light source are periodically changed. Illumination of plants in sheltered ground structures is realised on the basis of principle of doubling natural daily rhythm due to smooth changeover of illumination level from night to day and back. Changeover takes place twice a day, with account of change in moon and sun spectra of radiation. Besides peaks of maximum daily illumination correspond to moments of upper, daily, and lower, night, culminations of sun. Ratio of light and dark periods duration depends on extent of vegetative ripeness and type of grown crops.

EFFECT: method makes it possible to increase crop capacity by optimisation of light mode, to increase speed of plants growth, to reduce consumption of electric energy, as well as to expand range of application.
