Description

LED plant growth lamp and hydroponic cultivating apparatus equipped with LED plant growth lamp

The present invention relates to an LED plant growth lamp that can replace the lamp, and more specifically, it is possible to control the photosynthetic photon flux density by allowing the LED lamp to be replaced with a simple structure, as well as effective for the type and growth period of plants. It relates to an LED plant growth lamp that emits light of a wavelength to promote plant growth.

In general, plants grow through photosynthesis, and when vegetation is grown indoors where the amount of light for photosynthesis is absolutely insufficient, artificial light is used for most of the required light quantity by developing a complementary light cultivation technology that assists growth by irradiating artificial light. Therefore, the plant is growing.

Conventionally, as a light source, it was used as a light source having a wavelength similar to that of sunlight, such as an incandescent lamp. Recently, through many experiments and studies related to plant growth, light of a wavelength contributing to photosynthesis of plants is red and blue. It was found that the wavelength of is the most influential.

In other words, humans detect light in the range of 380nm to 780nm to distinguish between contrast and color, but plants react physiologically according to the wavelength of light, and blue light of 400nm to 500nm wavelength and wavelength of 640nm to 700nm to help plant photosynthesis By using the red light of the plant, it helps the plant growth, and if the light source is composed of wavelengths with high photosynthesis efficiency, the photosynthesis efficiency is high and the plants can grow faster and better.

Therefore, a light source having a wavelength similar to that of sunlight, such as a xenon lamp and an incandescent lamp, has been used in the prior art before a photosynthetic mechanism that greatly influences the photosynthetic action as described above was used. Since it is found that the greatest activation is possible, the use of a single-wavelength LED can reduce power use compared to examining the full-band spectrum of visible light, so the development of technology for agricultural LEDs using a single-wavelength LED lamp is actively progressing. have.

Photosynthetically active radiation Flux Density (PPFD) This represents the amount of photosynthetic photon emitted for 1 second per 1 square meter. It quantifies the amount of light required for plants, and because the required light environment for each plant is different, the LED is different. In the growth environment of plants using lamps, it is possible to further promote plant growth by appropriately controlling the ratio of the photosynthetic photon flux density emitted from each LED lamp and the wavelength of each color light, and it is possible to induce growth growth in various forms. have.

However, in the conventional plant growth lamp, since the intensity and light intensity (PPFD) values of the wavelength (nm) are already fixed at the time of shipment, it is impossible to supply the appropriate light to each cultivated plant when different types of plants are alternately grown. There is a problem that the growth promoting effect is weak.

In addition, when the plant growth lamp is mounted in a cultivation facility such as a hydroponic cultivation, there is a problem that the installation structure is complicated and the installation cost is very high.

In addition, if some of the LED lamps mounted on the growth lamp in the cultivation facility are broken, the entire LED bulb or the LED plate must be replaced, which is very cumbersome for the user to replace, and maintenance and repair costs due to parts replacement Too much occurs.

In addition, in the conventional cultivation facility, the mounting structure of the growth lamp is attached to the aluminum extruded material by attaching the LED-inserted PCB with adhesive tape, so that heat is released. As heat generated from the lamp is transferred to the upper layer, there is a problem that the plant roots are adversely affected, and the plant cannot grow or a growth disorder occurs.

The present invention is to solve the above problems, to provide an LED plant growth lamp made of a plate-shaped LED is equipped with two or more LED bars (bar) to emit light of an effective wavelength suitable for the type and growth period of the plant, grow This is to improve the mounting structure of the lamp so that the proportion of LED chips can be adjusted according to the type of plant and the time of growth to promote plant growth.

In addition, the installation of the LED plant growth lamp is facilitated, and the replacement of the LED bar is possible to facilitate maintenance, and heat generated from the growth lamp of the lower layer is transferred to the upper layer even when the cultivation facilities are formed in multiple layers. This is to prevent growth disorders by suppressing them.

The present invention as a technical idea for achieving the above object, the LED plant growth lamp is mounted on a cultivation facility where plants are planted to supply a light source to the plant, the base plate, a plurality of LED bars in parallel to the base plate In one state or both sides of the base plate in an arranged state, the LED bar is fixed to the base plate by a locking element so as not to be separated, and the LED bar is provided with a plurality of LED lamps. By separately separating the LED bar from the user, the user can replace the LED bar by themselves, and by selecting the wavelength required for plant growth, the ratio of the wavelength can be adjusted and the photosynthetic photon flux density can be adjusted according to the plant characteristics. will be.

In addition, by inserting the LED bar into the protective tube, the LED lamp is protected without being exposed to the outside, and the protective tube forms a fitting part on the inner surface of the through-hole so as to assemble the transparent light-transmitting part and the LED bar to allow the LED lamp to transmit light. By doing so, the LED bar can be easily separated and mounted, as well as being opened and closed by the locking element provided on the base plate, and the protective tube is made of a material having its own elasticity, so that the protective tube can be opened and opened. It was made easy to replace.

In addition, the base plate is embedded with a plate material to prevent heat generated from the growth lamp from being transferred to the upper layer, and the plate material is made of a lightweight material such as a composite plate composed of a synthetic resin material and an aluminum material superimposed.

According to the LED plant growth lamp of the present invention, in the case of a plant requiring more light of a red wavelength, the ratio of the red LED is a phone, and in the case of a plant requiring light of a red and blue wavelength evenly, the ratio of the two LEDs is similar. By properly adjusting the level, the user can directly adopt the combination ratio of red and blue to optimize plant growth.

In addition, by adjusting the luminous flux ratio, since it can provide a lighting device that is closest to the sunlight required for plant growth or has a better effect, the blue-based wavelength that helps to produce chlorophyll is grown in the seedling process after seed germination. In the process, it is possible to quickly grow into a healthy plant by using the red-based wavelength, so that even the general public who is not an expert can cultivate various kinds of plants according to the growth period. The nutrients can be further increased, and the growth stage and growth pattern of the root, stem, and leaves can be directly designed by the user.

In addition, the assembly structure of the frame can be simplified to easily install at a low cost, and if some LEDs have reached the end of their life, they can be replaced by directly replacing the LED of the corresponding part without the need for expert help. ,Management cost can be greatly reduced without the need for maintenance costs.

In addition, despite the simplified structure, there is almost no heat, so it can be used safely for a long time, and the life of the LED can be extended by suppressing heat generation. It does not occur and does not adversely affect plants, and even when the cultivation facilities are multi-layered, it is possible to contribute to promoting crop growth by maintaining the proper temperature without excessively increasing the temperature of the root portion of the upper plant.

Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

The LED plant growth lamp of the present invention is installed in a cultivation facility to promote plant growth, and a growth lamp is installed on the top of the cultivation box in which the plant is planted to supply a light source to the plant. 1 to 4 is composed of a base plate 100 and the LED bar 200 mounted to the base plate, as shown in Figure 4, the LED bar 200 is a plurality of LED on the base plate 100 In a state in which the bars are arranged in parallel, the LED bar 200 may be provided to be individually separated and replaced from the connector bar 150 provided in the base plate 100.

The LED bar 200 is a bar in a state in which a plurality of LED lamps 220 are arranged, and a fastening part 250 is formed at one end thereof and is separated from the connector bar 150 that is mounted on the base plate 100 and supplies power. It can be provided as possible.

At this time, the LED bar 200, even if several LED bars are connected or electrically connected in parallel by a connector bar 150, as shown in Figure 5, even if several LED bars are detached or replaced even when several LED bars are installed. It is possible to continuously supply light for plant growth without the need to power down.

In addition, in the case of a parallel structure, the connector bar 150 and the fastening part 250 are provided with inserting members 152 and 252 corresponding to each other so that the LED bar 200 can be easily separated individually. Can.

The LED bar 200 is a characteristic wavelength of a monochromatic light-emitting LED semiconductor required for photosynthesis and plant growth, and can be realized at an accurate wavelength effective for plant growth (blue: 450 nm / red: 660 nm), and the color purity is 100%. Can be.

The monochromatic light display through the LED lamp may be configured to display different monochromatic lights for each line of the LED bars 200 in which a plurality of lamps are arranged for each growth lamp unit, or to display a plurality of color lights selected from one LED bar 200. .

In addition, the LED bar 200 can adjust the ratio of the photosynthetic photon flux density emitted from each LED lamp and the wavelength of each color light by adjusting the ratio of monochromatic light having different wavelengths in order to realize the wavelength required for plant growth.

To this end, a plurality of LED bars 200 are arranged on the base plate 100, some of the LED bars are arranged with blue LED lamps, and some other LED bars are arranged with red LED lamps. The ratio can be adjusted by adjusting the mounting quantity and the mounting quantity of LED bars such as blue and red.

In addition, in order to finely control the quantity and light quantity of each LED lamp for each color, as shown in FIG. 6, some of the several LED lamps 220 provided in the LED bar 200 are blinded 222 or separately The resistor 224 may be mounted.

Therefore, because the required light environment is different for each plant, it is possible to provide a suitable light environment for each plant and further promote plant growth by adjusting the number of LED lamps and the ratio of the wavelength of light. By controlling the light environment, it is possible to induce the growth and growth of plants in various forms, such as allowing the leaves of a plant to grow small and thick, to grow large and thin, or to grow thick or thin and long stem diameters.

On the other hand, when the LED bar 200 is mounted on the base plate 100, the locking element 300 may be provided on one side or both sides of the base plate 100 so that the LED bar 200 is not separated. , LED bar 200 may be protected so that the LED lamp is not exposed to the outside by the protective tube 400.

The base plate 100 may be formed in a rectangular shape by assembling the frame bar 140 along the border of the plate 120, and the protective tube 400 is mounted on the plate 120 to the locking element 300. By doing so, it is possible to maintain a tightly mounted state without being separated.

The plate member 120 may be provided as a heat sink to prevent heat from being transferred to the upper layer portion, and even when used for a long time, the heat generation can be safely suppressed and the plant is not adversely affected.

To this end, the plate material 120 may be manufactured using a material that is lightweight and has a large heat insulation effect. Preferably, an aluminum composite board may be used to effectively block heat transmitted to the upper portion, and the structure has an insulating effect. A high synthetic resin material may be used that is formed by bonding aluminum plates to upper and lower surfaces.

The locking element 300 may be a cover plate 340 that is foldably provided on the frame bar 140 of the base plate 100, and the cover plate 340 is hinged while mounted on the frame bar 140. It can be mounted to open and close as a structure.

To this end, the frame bar 140 and the cover plate 340 are preferably formed with a hinge shaft and an axial groove corresponding to each other so as to be assembled by a simple fitting method by slide assembly. The cover plate is provided inside the cover plate 340. Elastic means, such as a leaf spring or a wire spring, may be provided so that the 340 has a transit force in an open or closed state.

At this time, the cover plate 340 is preferably to be disposed on both ends of the LED bar 200 is arranged, by placing the cover plate disposed on both sides to the front and rear of the hydroponic cultivation box is multi-layered In the arranged state, the user can open the cover plate 340 of the front or rear of the hydroponic cultivation device and easily replace the LED bar 200.

At this time, the protective tube 400 protecting the LED bar 200 is provided with an adhesive surface 410 on the back side for mounting to the base plate 100, and is transparent to allow light transmission of the LED lamp on the other side. It may be provided to have a light-transmitting portion 420, the through-hole 440 is formed so that the LED bar 200 can be accommodated on both sides of the protective tube, and the through-hole 440 can be assembled to slide the LED bar. A fitting portion 460 may be formed on the inner surface of the through hole.

The protective tube 400 is made of a polycarbonate (PC) material having high impact strength to prevent shock applied to the internal LED and block humidity.

The transparent portion 420 formed on the front surface of the protective tube 400 may allow a part of the protective tube to be formed transparently, or the entire protective tube 400 may be made of a transparent material, and the transparent portion 420 may be The surface is formed to be curved so as to have a constant curvature so that light emitted from the LED lamp 220 can be formed to diffuse in a wide range.

In addition, the protective tube 400 can be prevented from being randomly separated without flowing at all in a state mounted on the base plate 100 by being in close contact with the cover plate 340.

In addition, the protective tube 400 may be mounted by bonding the adhesive surface 410 on the back side to the plate material 120 of the base plate 100 by an adhesive element 450.

Here, the adhesive element 450 may be an adhesive, a double-sided tape, a removable Velcro tape, or the like.

In addition, the protective tube 400 is made of a synthetic resin material having its own elasticity, the protective tube 400 is mounted on the base plate 100, and the cover plate 340 is opened as shown in FIGS. When the end portion is pulled to the lower side, the LED bar 200 embedded in the protective tube 400 can be pulled out.

At this time, the length of the adhesive or the length of the adhesive element of the protective tube 400 and the plate member 120 is relatively shorter than the inner diameter of the base plate 100, so that one or both ends of the protective tube 400 are plated ( 120), the LED bar 200 can be withdrawn.

In addition, the end portion of the protective tube provided so as to be able to be separated from the plate member 120 is supported by the cover plate 340 as described above, and does not flow.

And when replacing the LED bar, the connector bar 150 formed on the base plate 100 and the fastening part 250 formed on the LED bar 200 are first separated, and then the LED bar is easily pulled out from the protective tube 400. On the contrary, when the LED bar 200 is to be reinserted, the LED bar 200 is first inserted into the protective tube 400, and then the fastener 250 is easily assembled to the connector bar 150. Replacement can be completed.

At this time, since the LED bar 200 cannot change the wavelength of light when the brightness changes, it cannot guarantee the desired growth effect. In order to prevent this, the LED bar 200 is not affected by changes in the surrounding environment and is constant. It is desirable that a constant current type design is performed so that light is emitted while current flows, and because the current of the LED lamp leads to heat generation due to the constant current type design, the current does not increase, so the luminance is kept constant and stable light is emitted to achieve the desired growth. The effect can be achieved.

At this time, the voltage for driving the LED may minimize heat generation by applying a voltage higher than the normal supply voltage.

In this case, since the blue LED has relatively more energy consumption than the red, the resistor can be properly inserted and configured to match the amount of power while using the same PCB as the red.

In addition, a blind 222 may be processed by soldering or the like to make some of the blue LEDs as a zero resistance, and a separate resistor 224 may be installed to finely adjust the power consumption in some of the blinded parts. Can.

Accordingly, for example, the power consumption of the LED bar 200 in which 16 blue LEDs and 24 red LEDs are mounted may have the same watt, so that LED bars of different colors can be replaced.

Therefore, by inserting the LED bar 200 having the power design as described above into the protective tube 400 as described above, it is possible to exchange and repair it without difficulty by using the elasticity of the two materials of the PCB and the protective tube constituting the LED bar. Since the LED bar 200 can be easily replaced, the proportion of the red LED and the more of the blue wavelength are required when more light of the red wavelength is required according to the characteristics of each planted plant or the development condition. Optimizing plant growth by increasing the ratio of blue LEDs when required, and when red and blue wavelengths are evenly required, by properly adjusting the ratio of the two LEDs to a similar level, by manually adopting the combination ratio of red and blue. Can be made.

In the cultivation box 10, a planting plate 12 may be formed to plant a plant on the upper side of the enclosure in which the inner space is formed, and in the inner space of the enclosure at the bottom of the planting plate, nutrient solution is used in the enclosure to supply nutrient solution to the plants. It can be configured to rise to a certain level so that it can be submerged to the root, or multiple nozzles can be installed in the space inside the enclosure to enable hydroponic cultivation by spraying nutrients to the roots to supply nutrients.

The cultivation box 10 may be composed of a single layer or a multi-layer, and multiple cultivation boxes may be arranged on the side, and for this purpose, the frame 20 may be manufactured according to its size.

The water tank 30 may be disposed at the bottom of the frame, and is connected to a cultivation box and a supply pipe to supply nutrient solution. The nutrient solution contained in the water tank 30 is supplied to the cultivation box 10 by a pump operation, The operation of the pump is controlled by a timer so that the nutrient solution can be supplied for a set time at regular intervals.

In addition, when the hydroponic cultivation 2 is made of a structure in which the cultivation box 10 is stacked in multiple layers, the growth lamp 1 is provided on the upper side of each cultivation box 10 to correspond to the stacked structure. In order to assemble (1) to the frame 20, a fixing holder 160 for fixing to the frame 20 may be further formed outside the rim of both sides of the base plate 100 constituting the growth lamp 1.

The fixed holder 160 is made of a structure corresponding to the outer shape of the pipe constituting the frame 20 to be installed on the upper end of the frame, or as shown in FIGS. 11 to 12, the fixed holder ( A fastening hole 164 is formed in the fastening plate 162 of 160, and a method of fixing with a cable tie or the like can be used.
