The invention relates to a device for irradiation of plants in a growth chamber at hydroponic greenhouses and can be used in agriculture.

A device for irradiation of plants in a growth chamber containing associated with power radiation sources for placement under the growth chamber, the upper part of the inner surface of the bulb of each of the radiation sources is covered with a reflective layer (A. F. Garden, VP Tips from the Mouth of the Xia inefficient use of light emission due to getting a significant portion of it is not on plants, and on the surrounding objects and uneven irradiation of plants, which does not allow to increase the productivity of cultivated device of plants, to achieve simultaneous ripening of the products and of the same quality, requires greater energy consumption.

Object of the invention is a device that provides efficient use of light radiation for irradiation of plants in cultivation under uniform irradiation, the energy savings of energy.

This problem is solved by the present invention.

The solution of this problem is achieved in that the device for irradiation of plants in a growth chamber containing associated with power radiation sources for placement above the growth chamber, the upper part of the inner surface of the bulb of each of the radiation sources is covered with a reflective layer according to the invention, each point of the bottom edge of the reflective layer on the inner surface of the bulb of each source of radiation for placement over rastila, is located on the straight line connecting the optimal center of this radiation source and the corresponding points of the edges of the germinator.

The coating frequent is the focus, and the installation of the light sources on the growth chamber in such a way that each point of the bottom edge of the reflective layer on the inner surface of the bulb of each source of radiation for placement over rastila, is located on the straight line connecting the optical center of this radiation source and the corresponding points of the edges of the germinator, and gives the opportunity to highlight strictly specified by the size of the germinator, preventing the escape of light fluxes beyond its boundaries, or lack of lighting at the borders. In addition, overlap each other, the light fluxes of different intensity from each source of radiation makes it possible to achieve uniform irradiation of all plants.

Comparable analysis with the prototype shows that the proposed device differs from the prototype in that the radiation sources used sources in part of the surface of the flask is covered with a reflective layer. Each point of its lower edge on the inner surface is located on the straight line connecting the optical center of this radiation source and the corresponding points of the edges of the germinator.

Thus the proposed technical condition meets the criteria for patentability izobreteniya signs on the achievement of the technical result - effective use of light radiation for irradiation of plants in their growth process under uniform irradiation and savings in energy costs, which allows to make a conclusion on the conformity of the proposed technical solutions to the patentability criteria of "inventive step".

The invention is illustrated in the drawing. In Fig. 1 is a cross-section of the device and the layout of radiation sources over rastila, Fig. 2 depicts a fragment of the device with the direction of light beams, and Fig. 3 shows an example of installation of radiation sources over rastila (patch).

A device for irradiation of plants in the growth chamber is located in a greenhouse containing the roof 1 and the frame 2. Inside the frame 2 is placed in the germinator 3 installed on them by a set of 4 light sources (radiation) 5 (Fig. 1) associated with the power supply (not shown). In the growth chamber 3 mounted on the supports 6 are plants 7 (Fig. 2). The upper part of the inner surface of the bulb of each of the light source 5 is covered with a reflective layer 8, such as aluminum, deposited in vacuum, and is installed above the growth chamber 3 in such a way that each point of the lower edge svetootrazauschii direct, connecting the optical center of this radiation source 5 and the corresponding points of the edges a, b, C and D. the germinator 3 (Fig. 3). The location of the border 11 reflective layer 8 on the bulb depends on the location of the radiation source 5 over rastila 3, which are installed from its center in mirror image with respect to the axes of symmetry of the germinator 3 (Fig. 1 and 2).

As radiation sources 5 can be used lamp type DM 1000. The area of the inner surface of the lamp is coated with reflecting material, is formed so that the light rays emanating from the lamp was projected on the square (or rectangle), congruently rastila. To establish the boundary of this region can be estimated by the methods (solving the system of equations describing the surface of the bulb, and planes drawn through the center of the lamp and limits the germinator). The height of the lamp under rastila determined so that the boundary of the square (rectangle), would coincide with the boundary of the germinator, and based on the required optical characteristics of the irradiation plants.

A device for irradiation of plants in the growth chamber works as follows.

In the germinator 3 planted seedlings of plants 7. Periodically, through zhdannikov, reflected from the inner surface of the flask is covered with a reflective layer 8, have a specific direction defined by the boundaries of the 11 reflective layer 8, covering the germinator 3 strictly from edge to edge, irradiating plants 7. Thus, each plant 7, for example, located at point a (Fig. 1), is irradiated same total luminous flux emitted by the light sources 5, mounted on rastila 3, despite the fact that light emission from each light source 5 at this point And has a different intensity.

The proposed solution can be used in agriculture and in devices for irradiation of plants in their growth process.

The claimed invention disclosed in the application materials in sufficient detail to implement, and allows for the efficient use of light radiation for irradiation of plants with homogeneous irradiation and energy cost savings.

The use of the claimed technical solution can increase the yield of production by 15 to 20% while it is maturing and improving the quality, reduce energy costs for exposure to more than 50%

Thus, the LASS="ptx2">
