The medium unit 10 is composed of a multi-layer can be grown on the top crops.

As shown in FIG. 2, the medium part 10 includes a medium 11 on which a cultivated crop is grown, a fixing part installed on the bottom, and a medium 11 stacked in multiple layers, and a bottom of the medium 11. It is formed on the side is made of a diffuse reflection film to reflect the light reflected from the upper medium 11 of the lower layer again diffused to the cultivated crop grown on the lower medium (11).

The medium 11 is formed with a plurality of through holes (not shown) on one side, the light collecting unit 20 is installed through.

That is, the light collecting unit 20 penetrates the roof of the cultivation greenhouse 1 and is installed vertically on the upper surface of the medium 11 to irradiate light onto the medium 11 of the upper layer, and the medium consisting of multiple layers through the fixing unit ( 11, the light collecting part 20 is penetrated through a through hole (not shown) formed at one side of the medium 11 to irradiate light to the lower medium 11.

Then, when the light irradiated to the medium 11 of the lower layer is reflected to the medium 11 of the upper layer by the cultivated crop and the medium 11, the diffuse reflection film is formed to diffuse the reflection back to the upper surface of the medium 11 of the lower layer.

Therefore, the amount of light similar to the medium 11 of the upper layer is also irradiated to the lower medium 11 so that the cultivation of the cultivated crops can be made uniform.

As shown in FIG. 3, the light collecting unit 20 is installed to penetrate the roof or the side surface of the cultivation room 1 so that external light is irradiated to the medium 11 inside the cultivation room 1.

The light collecting unit 20 is composed of a lens unit 21, an upper portion 22, a transmission portion 23, and a lower portion 24.

The lens unit 21 is configured as a convex lens to collect external light. The reason why the lens unit 21 is configured as a convex lens is that light is transmitted through the convex lens and is transmitted to the transmission unit 23 even when light is introduced at any angle.

The upper part 22 is formed in a funnel shape, the lens part 21 is coupled to the upper side, and the transmission part 23 is coupled to the lower side through the coupling protrusion 40. A coating layer 25 coated with a reflective material is formed on the inner circumference of the upper part 22 to transmit the light collected through the light collecting part 20 to the transmission part 23.

The transmission unit 23 is coupled through the upper portion 22 and the coupling protrusion 40, the coating layer 25 is formed in a cylindrical shape and coated with a reflective material on the inner circumference is formed to transmit the light transmitted from the upper portion 22 Is transmitted to the lower part 24.

The lower part 24 is formed in a reverse funnel shape to form a coating layer 25 coated with a reflective material on an inner circumference thereof, and is coupled to the transmission part 23 through the coupling protrusion 40.

A gasket 41 is interposed between the upper part 22 and the transmitting part 23 and between the connecting part 40 formed between the transmitting part 23 and the lower part 24 to seal the connecting part 40.

The coupling protrusion 40 is inserted into insertion grooves formed on both sides of the gasket 41 to form an insertion protrusion for preventing the gasket 41 from being separated between the coupling protrusions 40.

Outlet 26 is formed on the outer circumference of the transmission unit 23, the outlet 26 is connected to an external vacuum pump (not shown), the lens unit 21, the upper portion 22, the transmission unit 23 The lower part 24 discharges the air inside the light collecting part 20 coupled to the outside. As a result, the interior of the light collecting unit 20 is in a vacuum state, and is installed in the cultivation greenhouse 1. The reason for making the interior of the light collecting unit 20 in a vacuum state is to prevent dust contained in the air inside the light collecting unit 20 from scattering light collected through the lens unit 21. This is to prevent a phenomenon in which moisture is agglomerated inside the miner 20.

As shown in FIG. 4, the light collecting unit 20 may adjust the length by connecting a plurality of transmitting units 23 coupled thereto.

As shown in FIG. 5, the transmission unit 23 may be formed to be bent.

Even if the transmission part 23 is bent in this way, the light may be irradiated into the cultivation greenhouse 1 due to the coating layer 25 formed on the inner circumference.

The light collecting part 20 may be made of any one of metal, glass, or plastic material, and preferably, plastic material.

The reason why the light collecting part 20 is made of a plastic material is because the manufacturing cost is low, the weight is light, and the durability is good.

As shown in FIGS. 1 and 2 and 5, a side of the cultivation greenhouse 1 is provided with a light metering portion 30 for reflecting the light of the side in the longitudinal direction into the cultivation greenhouse 1.

As shown in FIG. 6, the light metering portion 30 is formed in a side tube 31 formed in a tubular shape, a first reflective layer 32 formed in an inner circumference of the side tube 31, and an inner center of the side tube 31. The heating tube 33 provided and the 2nd reflective layer 34 formed in the outer periphery of the side pipe 31 are comprised.

The side pipe 31 is made of a transparent material, is formed in a cylindrical tube shape. The side pipe 31 may be made of glass or transparent plastic material.

The first reflective layer 32 is made of a reflective material and is formed at a predetermined angle on the inner circumference of the side pipe 31. The first reflective layer is made of both the inner surface and the outer surface bonded to the side pipe is a reflective surface can reflect external light depending on the purpose.

The first reflective layer may collect light to heat the inner heating tube, and the outer surface may reflect light from the outside to irradiate light into the cultivation greenhouse.

The angle at which the first reflective layer 32 is formed on the side surface of the side pipe 31 may be formed at 100 to 130 °.

When the angle of the first reflective layer 32 is less than 100 °, the irradiation amount of light for heating the heating tube 33 installed at the center of the side tube 31 is insufficient, so that the heating tube 33 may not be heated. When the angle of the first reflective layer 32 is greater than 130 °, the first reflective layer 32 blocks the light flowing into the side tube 31 to heat the heating tube 33. A problem may occur in which the dose is reduced.

A heating tube 33 is installed at the inner center of the side tube 31. The heating tube 33 may be configured as a general heating pipe.

The heating tube 33 is heated by the light reflected and collected through the first reflective layer 32 formed on the inner circumference of the side tube 31, the heat of the heated heating tube 33 is the interior of the cultivation room (1) It is used to heat it. The heating tube 33 may heat the inside of the cultivation chamber 1 by dissipating heat when heated, and connects a circulation pump (not shown) to both ends of the heating tube 33 to heat the heat of the heating tube 33. The inside of the cultivation greenhouse 1 may be heated by circulating.

A second reflective layer 34 made of a reflective material may be formed on the outer periphery of the side pipe, and is formed on the outer periphery of the side pipe 31 on which the first reflective layer 32 is formed, and light is directed into the side pipe 31. The second reflective layer 34 is not formed in a portion where the first reflective layer 32 is not formed so as to flow in. The reason for this is to prevent the second reflective layer 34 from blocking the entrance of light into the side pipe 31.

When increasing the irradiation amount of light in the cultivation greenhouse (1) to rotate the side pipe 31 so that the second reflective layer 34 is located upwards so that the external light is reflected into the cultivation greenhouse (1) to be introduced. Can be.

The method of installing the above invention is as follows.

A coating layer 25 coated with a reflective material is formed on the inner circumference of the light collecting unit 20, and the light collecting unit 20 is installed through the roof or side surface of the cultivation greenhouse 1.

In this case, the light collecting part 20 is installed in a plurality so that light is irradiated to the lower discharge part 10 through a through hole (not shown) of the discharge part 10 formed in a multilayer. The length of the light collecting part 20 is adjusted by combining a plurality of transmitting parts 23.

When the condenser 20 is installed, the condenser 26 is connected to the outlet 26 formed at the outer circumference of the transmission part 23 of the condenser 20 and a vacuum pump (not shown) to collect the condenser through a vacuum pump (not shown). 20) Exhaust the air inside. As a result, the inside of the light collecting unit 20 is in a vacuum state.

When the light is irradiated to the cultivated crops on the medium unit 10 through the light collecting unit 20, the light is reflected from the medium 11 and the cultivated crop due to the diffuse reflection film formed on the bottom surface of the medium 11 of the medium 11. Light is diffusely reflected and irradiated to the cultivated crop side of the lower layer medium 11 again.

If the amount of light irradiated through the light collecting unit 20 after forming the light collecting unit 20 and the discharge unit 10 is insufficient, the light metering unit 30 installed in both longitudinal directions of the cultivation greenhouse 1 is rotated. By making the outer side of the first reflective layer 32 face upward, the light of the side is reflected and irradiated into the cultivation greenhouse 1 through this.

When the internal temperature of the cultivation greenhouse 1 is low, the heating tube 33 is heated by light by rotating the light metering portion 30 so that the reflective surface formed on the inner surface of the first reflective layer 32 faces upward. It is to be able to heat the inside of the cultivation room (1) by the heat released.

The present invention configured as described above condenses the external light through the light collecting part and irradiates each layer of the medium part consisting of multilayers inside the cultivation greenhouse, and diffuses it with the diffuse reflection film formed on the lower side of the medium, thereby irradiating a large amount of light to the cultivated crop at night. There is an advantage that the cultivated crops can grow sufficiently without irradiating the cultivated crops, and heating the inside of the cultivation greenhouse by irradiating the side light into the cultivation greenhouse through the metering unit or by heating the heating tube. There is a declining advantage.
