The number of LED holes 414a disposed in the fourth area 415g may be smaller than the number of LED holes 414a disposed in the second area 415e or the third area 415f. For example, two LED holes 414a may be disposed in the fourth region 415g.

In addition, the distance between both sides of the LED holes 414a on the fourth area 415g may be narrower than the distance between both sides of the LED holes 414a on the second area 415e or the third area 415f. Accordingly, the number of LED holes 414a on the fourth area 415g may be smaller than the number of LED holes 414a on the second and third areas 415e and 415f, and the distance between both sides may be narrower.

As such, the number of LED holes 414a provided in the front module mounting portion 415 is greater than the number of LED holes 414a disposed in the first half 415a than the number of LED holes 414a disposed in the second half 415c. Many can be placed.

In addition, the distance between both sides of the LED holes 414a may be narrower from the center to both sides (from the first area to the fourth area). Also, the LED hole 414a may not be disposed at the center of the front module mounting portion 415, and the LED hole 414a may be disposed only at the center of the front half 415a.

In addition, the distance between the LED holes 414a may be narrowed overall as the center of the front module mounting portion 415 approaches the corner.

Meanwhile, the arrangement of the LED holes 414a disposed in the rear module mounting part 416 may be formed differently from the arrangement form of the LED holes 414a disposed in the front module mounting part 415 .

The rear module mounting portion 416 is partitioned in the front and rear directions and can be divided into a front half 416a, a middle section 416b, and a second half 416c.

The fifth area 416d is the first area 415d, the sixth area 416e is the second area 415e, and the seventh area 416f is the third area 415f. The eighth area 416g may be partitioned so that the location and size of the fourth area 415g correspond to each other.

In the rear module mounting portion 416, the number of LED holes 414a disposed in the first half 416a may be greater than the number of LED holes 414a disposed in the second half 416c. Further, in the rear module mounting portion 416, a distance between both sides of the adjacent LED holes 414a may be narrower toward both sides from the center.

Looking in more detail with reference to the drawings, the LED hole 414a may not be disposed in the fifth region 416d of the first half of the rear module mounting portion 416 .

In addition, a plurality of LED holes 414a may be disposed in the sixth area 416e of the first half at regular intervals. The LED holes 414a disposed in the second area 415e of the front module mounting part 415 ) can be arranged less than the number of For example, two LED holes 414a may be disposed on the sixth area 416e of the first half, and the distance between the LED holes 414a may be disposed in the second area 415e on the front module mounting part 415. It may be disposed wider than the interval between the LED holes 414a.

Also, the LED holes 414a disposed in the seventh region 416f of the first half may be disposed corresponding to the arrangement of the LED holes 414a on the third region 415f. Accordingly, the distance between the LED holes 414a on the seventh area 416f may be narrower than the distance between the LED holes 414a on the sixth area 416e.

In addition, the LED holes 414a disposed in the seventh area 416f of the first half may be spaced apart in plurality corresponding to the arrangement of the LED holes 414a on the fourth area 415g of the front module mounting part 415. can

In this way, the LED holes 414a disposed in the front half 416a of the rear module mounting portion 416 may be formed such that a distance between the LED holes 414a becomes narrower toward both sides with respect to the center. In other words, the distance between the LED holes 414a disposed in the front half 416a of the rear module mounting portion 416 is greater than that in the order of the sixth area 416e, the seventh area 416f, and the eighth area 416g. can be narrowed

Also, the number of LED holes 414a disposed on the seventh region 416f may be greater than the number of LED holes 414a disposed on the sixth region 416e.

In addition, the LED holes 414a disposed in the central portion 416b of the rear module mounting portion 416 correspond to or have the same arrangement as the arrangement of the LED holes 414a disposed in the front half 416a of the rear module mounting portion 416. can Accordingly, the central portion of the rear module mounting portion 416 may be formed so that the distance between the LED holes 414a becomes narrower from the center toward both sides. In other words, the gap between the adjacent LED holes 414a may be narrower from the fifth area 416d to the eighth area 416g. The total number of LED holes 414a disposed in the seventh region 416f is greater than the total number of LED holes 414a disposed in the fifth region 416d and the sixth region 416e. There can be many.

The total number of LED holes 414a disposed in the front half 416a and the central part 416b of the rear module mounting part 416 is the number of LEDs disposed in the front part 415a and the central part 415b of the front module mounting part 415. Fewer than the total number of holes 414a may be disposed. Therefore, the interval between the LED holes 414a may be formed wider than that. In particular, the distance between the LED holes 414a disposed on the sixth area 416e of the rear module mounting part 416 is larger than the distance between the LED holes 414a disposed on the second area 415e. The total number of LED holes 414a on the sixth area 416e may be less than the total number of LED holes 414a on the second area 415e.

In addition, the LED hole 414a disposed in the rear part 416 of the rear module mounting part 416 is not provided on the fifth area 416d, and the LED hole 414a on the sixth area 416e is the rear part. The arrangement of the LED holes 414a of the front half 416a or the center 416b of the module mounting part 416 may correspond to or be the same as the arrangement.

Also, the arrangement of the LED holes 414a disposed on the seventh area 416f of the rear part 416 of the rear part 416 is the third area 415f of the rear part 415c of the front module mounting part 415. It may be formed corresponding to or identical to the arrangement of the LED holes 414a disposed thereon. In other words, the LED holes 414a on the seventh area 416f are wider than the distance between the LED holes 414a disposed on the central portion 416b of the rear module mounting part 416 and the seventh area 416f. and may be arranged narrower than the interval between the LED holes 414a disposed on the second half sixth region 416e. In this structure, the total number of LED holes 414a disposed on the rear part 416c of the rear module mounting part 416 is smaller than that of the front part 416a or the central part 416b. In addition, the difference between the distance between the LED holes 414a on the sixth region 416e and the distance between the LED holes 414a on the seventh region 416f of the second half 416c compared to the first half 416a or the middle 416b is can be smaller

And, the LED hole 414a disposed on the eighth area 416g of the rear part 416 of the rear module mounting part 416 is the LED hole 414a disposed on the eighth area 416g of the first half or the central part. It can be arranged to correspond to the arrangement of.

As such, the total number of LED holes 414a disposed on the rear module mounting portion 416 may be less than the total number of LED holes 414a disposed on the front module mounting portion 415. .

In addition, the distance between the LED holes 414a disposed on the rear module mounting part 416 may be wider than the distance between the LED holes 414a disposed on the front module mounting part 415 as a whole.

An LED module 42 configured by mounting a plurality of LEDs 422 on a substrate 421 may be mounted on the module mounting portion 413 . Also, the LED 422 may be disposed at a position corresponding to the LED hole 414a to irradiate light capable of promoting photosynthesis of plants.

Also, the LEDs 422 may be arranged to correspond to the arrangement of the LED holes 414a. Accordingly, the LEDs 422 may be arranged such that the total number of the LEDs 422 decreases from the front to the rear, and the interval between the LEDs 422 widens from both sides to the center. With this arrangement, there is an advantage in that light irradiated from the LED 422 can be uniformly provided within the cultivation space 100 .

17 is a view showing the amount of light provided to the cultivation shelf according to the change in the arrangement of the LEDs. As shown, when the LED holes 414a are arranged on the module mounting portion 413 according to an embodiment of the present invention, the effect of evenly irradiating light to the entire area of the cultivation shelf 30 there is.

In detail, when the same number of LEDs 422 are arranged in the front-back direction and the spacing between the LEDs 422 is uniformly arranged as a whole, the amount of light provided to the upper and lower cultivation shelves 30 is greater than that of the rear part. There is a problem in that the light is not concentrated and uniformly irradiated.

A door 13 made of a glass material is provided in front of the lighting device 40, and an inner case 12 made of a metal material is provided at the side and rear of the lighting device 40. That is, the light reflectance may be different depending on the position where the light is irradiated from the lighting device 40 .

In detail, a door 13 made of a glass material is provided in front of the cabinet 10, and a portion of the light passes through the door 13 and is emitted to the outside of the cabinet 10, and a portion of the light is transmitted through the door 13. ) and can be irradiated to the cultivation shelf 30. That is, the light irradiated from the lighting device 40 can be transmitted through the door, so that the amount of light reaching the first half of the cultivation shelf 30 is relatively smaller than the amount of light reaching the second half of the cultivation shelf 30. .

In addition, the inner case 12 forming the side surface and rear surface of the cabinet 10 is made of a metal material so that the degree of reflection or scattering of light is higher than that of the door 13 . That is, the amount of light reaching both sides and the rear half of the cultivation shelf 30 is relatively greater than the amount of light reaching the first half of the cultivation shelf 30.

That is, the inner case 12 made of a material having high light reflectivity is located behind the lighting device 40, so that the amount of light irradiated to the rear of the cultivation shelf 30 is equal to the amount of light irradiated to the front of the cultivation shelf 30. relatively more than the amount.

Therefore, the degree of reflection or scattering of light is different from the front, side, and rear surfaces of the cabinet 10, making it difficult to provide uniform light to the cultivation shelf 30.

In the lighting device 40 according to an embodiment of the present invention, the number of LEDs disposed in the rear half is smaller than the number of LEDs disposed in the first half of the arrangement of the LEDs 422, so that the inner case ( 12) and the amount of light reflected from the front door 13 were made uniform. That is, more LEDs 422 are disposed in the first half of the lighting device 40 than in the second half, so that a uniform amount of light can be provided to the entire cultivation shelf 3.

In addition, when the arrangement of the LEDs 422 is arranged with a constant distance between the center and both sides, the light irradiated from each of the LEDs 422 overlaps and is concentrated in the center. Therefore, considering the overlapping range where the light is irradiated, the distance between the LEDs is arranged on both sides of the light case 41 to be narrower than the central portion, so that the light is concentrated in the center and irradiated.

Therefore, regardless of where the seed package 90 is placed on the cultivation shelf 30, it is possible to provide uniform light. If the amount of light reached is different depending on the location of the cultivation shelf 30, there is a problem in that the growth rate of cultivated plants varies depending on the location of the cultivation shelf 30 in which they are seated, so that they do not grow uniformly. As a result, the harvesting time of the plants is different from each other, causing inconvenience to the user.

According to the lighting device 40 according to an embodiment of the present invention, the amount of light irradiated is uniform throughout the cultivation shelf 30, so there is an advantage in that the growth rate of cultivated plants can be equally matched.

Meanwhile, in the light groove 414 formed in the module mounting portion 413, both sides of the light groove 414 are inclined around the LED hole 414a, so that the light emitted from the LED 422 It is reflected through the light groove 414 so that it can be irradiated downward.

FIG. 10 is a XX-X' cross-sectional view of FIG. 7 .

The upper end of the light groove 414 is opened to form an LED hole 414a, and the LED 422 is formed in the LED hole 414a. can be inserted. Further, the light groove 414 is formed with both sides inclined around the LED hole 414a, and the opened lower end of the light groove 414 may be shielded by the light cover 43.

As a whole, an inner surface of the light groove 414 may be inclined in a direction away from the center of the LED hole 414a from top to bottom. In addition, the inner surface of the light groove 414 may include two stages of inclination by varying the inclination angle.

In detail, the light groove 414 includes a first inclined portion 414b extending downward from the LED hole 414a into which the LED 422 is inserted, and the first inclined portion 414b. A second inclined portion 414c extending to a lower end of the light groove 414 may be formed. In addition, the first inclined portion 414b and the second inclined portion 414c may be formed with different degrees of inclination.

For example, the second inclined portion 414c may be formed to have a relatively gentler slope than the slope of the first inclined portion 414b.

In other words, the light groove 414 has an inclination in a direction away from the center of the LED hole 414a as it goes downward with respect to the LED hole 414a. It may include a first inclined portion 414b and a second inclined portion 414c. That is, the first inclined portion 414b and the second inclined portion 414c may be connected by a stepped portion 414d. The stepped portion 414d connects the lower end of the first inclined portion 414b and the upper end of the second inclined portion 414c in a horizontal direction.

As such, the light groove 414 according to an embodiment of the present invention is characterized in that the inner surface has two or more inclined surfaces. Accordingly, the light emitted from the LED 422 is provided to the cultivation space 100 via the first inclined portion 414b and the second inclined portion 414c.

If the inner surface of the light groove 414 is formed as a single inclined surface, when the lighting device 40 is viewed from the outside, the LED 422 appears relatively prominent in the light case 41. do. In addition, when the light groove 414 is formed as a single inclined surface, a line in the form of a dot (spot) is illuminated in the cultivation space 100 by the degree of spread of the light irradiated from the LED 422. there is.

The light groove 414 of one embodiment of the present invention forms a first inclined portion 414b and a second inclined portion 414c having different inclinations, thereby minimizing exposure of the LED 422 when viewed from the outside. While doing so, the light was allowed to be irradiated to the surface of the cultivation shelf 30. Accordingly, there is an advantage in preventing a spot-shaped line from being generated due to concentration of light irradiated within the cultivation space 100 .

That is, as shown in FIG. 4 , the air inside the cultivation space 100 is circulated by the blower 50 . In addition, the air circulated by the blower 50 flows while passing through the upper surface of the cultivation shelf 30 and the lower surface of the lighting device 40 .

At this time, the temperature sensor 476 is accommodated in the temperature sensor mounting portion 47 protruding downward from the lower surface of the light case 41, and is affected by the temperature of the lighting device 40 as little as possible. The temperature of the air passing through the lower surface of (40) can be more effectively sensed.

In addition, the temperature sensor mounting portion 47 protrudes downward from the bottom surface 411 of the light case 41 to form a temperature sensor rim portion 472 . If the temperature sensor 476 comes into direct contact with the air passing through the lower surface of the lighting device 40, the temperature sensor 476 is directly affected by this air flow, and thus the cultivation space 100 Errors may occur when measuring the average temperature of The present invention has an advantage in that the temperature sensor 476 can measure the average temperature of the entire cultivation space 100 by forming the temperature sensor edge portion 472 .

To mount the temperature sensor 476 on the temperature sensor mounting portion 47, a plurality of protrusions protruding upward from the bottom surface of the temperature sensor mounting portion 47 may be formed. In detail, the temperature sensor mounting part 47 may include a first protrusion 473 formed to fix the center of the temperature sensor 476 .

It can be judged as the lowest water level. In this state, when the set time condition is satisfied, water supply to the cultivation shelf 30 is possible.

And, when water is supplied to the cultivation shelf 30, the water level sensing member 34 moves upward according to the water level of the cultivation shelf 30, and gradually contacts the bottom surface of the water level detection unit 317f. it gets farther away In addition, the water level detecting device 493 detects that the strength of the magnetic field gradually weakens as the water level detecting member 34 moves away.

At this time, when an amount of water exceeding the full water level H2 is supplied to the cultivation shelf 30, the water level detecting device 493 may detect this. In general, the amount of water supplied to the cultivation shelf 30 is controlled by the operation time of the pump 83, but the water level of the cultivation shelf 30 is caused by other factors such as abnormality of the pump 83 or poor drainage. may be above the full water level.

When the water level detecting device 493 detects that the water level of the cultivation shelf 30 becomes an abnormal water level (H3) equal to or higher than the full water level (H2), the water supply to the cultivation shelf 30 is stopped. That is, when the water level of the cultivation shelf 30 is higher than necessary, the water overflows to the outside of the cultivation shelf 30 or subsequent drainage and water supply operations may not be performed smoothly, so the driving of the pump 83 may be stopped or the driving device 86 may be driven to forcibly drain the water from the cultivation shelf 30.
