Abstract

The present invention relates to a light emitting diode lighting tool to grow a stem plant. More specifically, an air feeding and ventilating guide is installed in the center in the lighting tool equipped with a ventilating fan to radiate heat generated from LEDs, such that indoor air can easily be suctioned or heat in the tool can be diffused to the side of a growing plant. Also, specific temperature sensors are respectively installed inside and outside of the lighting tool. Accordingly, if an indoor temperature around the growing plant is higher than 37±2°C in a state wherein the temperature in the lighting tool is 45-60°C due to the heating of the LEDs, the ventilating fan is operated in order to feed indoor air to be discharged to the outside through an air exhausting mode (upward), such that heat in the lighting tool is radiated. When the indoor temperature around the growing plant is less than 37±2°C in a state wherein the temperature in the lighting tool is 45-60°C, heat in the lighting tool is discharged in a form of a warm air towards the growing plant. When the temperature in the lighting tool is less than 45-60°C, the operation of the ventilating fan is blocked. Consequently, the radiating function of the lighting tool can actively be performed, and a small quantity of heat is generated, such that the lighting tool can access the plant, has high optical efficiency, and can actively irradiate light to grow the plant (photosynthesis). Warm air heating is possible using waste heat generated in the lighting tool, such that unnecessary heating costs can remarkably be reduced.

Description

Horticulture emitting diode lighting device [0002]

The present invention relates to a light emitting diode lighting apparatus for cultivating a stem plant, and more particularly, to an LED lighting module composed of a plurality of light emitting diodes (hereinafter referred to as "LEDs"), It is possible to grow light and heating warm air. It can access plants with low heat of generation, has high light efficiency, and has an intangible (radiance; Shadowless lens and LED lighting modules employing the lens are arranged in a radial manner so that light radiated vertically or obliquely to the crop growing area can be radiated uniformly without shading, (Heating) required for photosynthesis in the cultivation of crops is performed by using the waste heat generated during the heat dissipation of the LED lighting module, The amount may contribute to the reduction cultivation efficiency increases and expensive to control (Dimming), and the invention will allow the water-proof and moisture-proof can be freely used regardless of location.

Generally, techniques using artificial light sources in cultivating various plants have been widely studied such as application of plant plant system in recent years.

In addition, along with the emergence of LEDs, the current agriculture sector is in the process of turning a further point. In contrast to conventional lighting, which has a wide wavelength range and is adapted to human vision, LEDs are capable of adjusting the emission wavelength ratio and intensity It is possible to provide a wavelength and a light amount necessary for photosynthesis, thereby facilitating plant cultivation illumination.

If such an artificial lighting device using LED is used, it is possible to control the growth of the plant by using no or little chemical fertilizer, effectively irradiating the light, and by applying LED light technology to control pests, low pesticide cultivation is possible , And can save over 80% of energy compared to incandescent bulbs that are in use. It is an eco-friendly product that does not use mercury or heavy metals. It can produce 365 days a year, regardless of climate change.

On the other hand, the intensity of light is closely related to the intensity of photosynthesis, which affects the plant growth and plant morphology, and the visible light has the greatest influence on the growth of crops such as light, infrared, visible and ultraviolet.

In other words, it is a well-known fact that the optical wavelength of a specific band influences plant cultivation.

For example, in the case of blue light, stem and roots are grown to make it thicker, especially roots are thicker and roots are enlarged (root roots). Red light (660 nm) promotes the growth of leaves and stems to produce chlorophyll and acts on photosynthesis In addition, it is known that yellow or primary colors are effective for insect pests. Especially, according to the study on the distribution of spectral radiant energy of sunlight and the wavelength range effective for plant cultivation, the graph shown in FIG. 1 and the following Table 1 >.

The term "photosynthesis" refers to the use of light energy in the chloroplasts of plant cells to produce organic matter from minerals and organic matter from water and carbon dioxide, and to produce oxygen necessary for glucose and respiration. It absorbs light energy from the chlorophyll, which has a green pigment in the chloroplast, which causes photosynthesis.

Water, carbon dioxide and light energy are required for such photosynthesis. Water is absorbed through the roots and then the water pipe is used as the leaves. The carbon dioxide absorbs the carbon dioxide in the air through the pores of the leaves. Energy is an energy source (chlorophyll absorbs light energy) that supplies the energy needed for photosynthesis.

In addition, there are carbohydrates (organic nutrients) produced through photosynthesis, and starch as a form in which glucose and glucose are stored as organic nutrients originally made through photosynthesis. These starches are stored temporarily in the leaves, It breaks down into glucose, and there is also oxygen that is released through the pore, which is used for its own breathing.

In addition, the photosynthetic products are expressed in the form of glucose -> starch (temporarily stored in the leaves) -> glucose (moving to each tissue through night) -> starch (nutrient storage) Is used as a "source of energy" for living, and as a constituent of plants, and is stored in storage facilities such as "root, stem, fruit".

The intensity of light is increased as the intensity of light is strong as shown in the graph of FIG. 2, but the amount of photosynthesis increases as shown in FIG. 3 (a) and (b) , The photosynthetic rate increases as the carbon dioxide concentration increases. However, as the concentration increases, the photosynthetic rate increases from 0.1%. The higher the temperature, the more photosynthetic amount increases, but the most active at 35 ~ 38 ℃ However, at 40 ° C and below 10 ° C, photosensitivity is abruptly decreased. At this time, photosynthesis is caused by the main component enzyme of the protein. If the temperature is too high, the activity is lost and the reaction does not occur well.

In addition, the phenomenon that the water in the plant leaves the plant through the pore in the form of water vapor is called the hypercapnicism. Such regulation of the hyperproliferation is controlled by opening and closing the pores by the cocoon cells.

In other words, when the pore is opened, the concentration of the guanosine is increased by the photosynthetic activity of the guinea cell -> glucose production -> the water absorption from the surrounding cells (osmotic phenomenon) -> the cell absorbs water, When the pore is closed, the concentration of the cells in the cell is lowered due to the interruption of photosynthesis at night. -> The water of the guinea cell is released into the surrounding cells. -> Decreases the pressure of the proximal cells and then closes the pores.

 At this time, the significance of the vaporizing action acts as a "driving force for raising water" absorbed in the root, controlling the "body temperature" of the plant, controlling the "water content" in the plant, and accumulating "inorganic nutrients" .

In addition, the driving force of water rising from the plant is the pressure (root pressure) of the root, which is the "power pushing up" the water absorbed by the root of the plant by the absorption or attracting power (the greatest driving force) The cohesive force of water "pulling each other" and the phenomenon of capillary phenomenon, in which water rises along a "thin tube" like a water tube.

In addition, if we look at the gas exchange of plants, we see that photosynthesis is more absorbed than respiration during the day, so it absorbs carbon dioxide and releases oxygen. In the morning and evening, photosynthesis and respiration are the same so that the gas circulates inside, It does not emit, it does not have light at night, it only breathes, it absorbs oxygen and releases carbon dioxide.

In addition, all plants exhibit a bulging phenomenon that curves in the direction in which light is irradiated. This is due to the fact that the dioxin present in the plant hates the light, so that much of the light is generated on the opposite side of the light, Therefore, the phenomenon of baking appears.

In other words, the plants respond to the direction in which the light is irradiated to the plant and the flexion reaction occurs in the plant. This phenomenon can be explained by the physiological relationship between light and ozone.

When the light was irradiated to only one side of the leaf, and the tip of the leaf was cut to measure the distribution of the dioxins in the irradiated and non-irradiated regions, it was found that the amount of the dioxins in the irradiated areas was larger.

Therefore, the dioxin shifts more toward the dark side of the early lobe and promotes the growth of the dark side, so that it is bent toward the direction in which the light is irradiated, and such a luminescence phenomenon is effective in the wavelength range of 440 to 480 [nm].

Conventionally, most of the luminaires for plant cultivation use incandescent lamps, fluorescent lamps, sodium lamps, etc. in order to supplement the insufficient amount of light or to provide appropriate growth conditions for controlling flowering, coloring, etc. However, And the wavelength of a specific band is required, unnecessary wavelengths are also irradiated.

Conventionally, in some cases, a light source such as a light emitter diode (LED) capable of intensively irradiating light of a specific wavelength range for promoting photosynthesis may be used instead of a lighting apparatus such as an incandescent lamp or a fluorescent lamp for irradiating light of all wavelength ranges Techniques have been proposed for use in plant cultivation.

Such a conventional illuminator having an LED light source is disclosed in Korean Patent Registration No. 10-0902071 entitled " Method and Apparatus for Cultivating Plants Using LED Lamp ", and Patent Publication No. 10-2004-0010426 " Quot ;, Patent Registration No. 10-0879711 "Lighting apparatus for plant cultivation with LED ", and Korean Patent Laid-open Publication No. 10-2009-0124155 entitled " Plant cultivation luminaire using LED and intelligent optical environment control system" .

Conventionally, most conventional plant lighting apparatuses using LED as a light source mix blue light and red light at a fixed ratio, and repeatedly turn on and off while having a pulse cycle in which the rate of photosynthesis is maximized Consists of.

However, depending on the plant species, or depending on the growth period of various plants such as seedlings, differentiation, fruiting, and deletion, not only promoting photosynthesis but also controlling the wavelength range of the light source in various ways such as promoting morphogenesis and flower bud differentiation .

Since the wavelength ranges necessary for each plant growth period are different, there is a problem in that the optimal plant cultivation can not be achieved with only the conventional lighting apparatus having a fixed mixing ratio. Therefore, in order to effectively cultivate plants, In the construction of the lighting device, not only the promotion of photosynthesis but also the promotion of photosynthesis can be achieved by controlling the light of the wavelength band optimized for the growth period of various kinds of plants, which are classified into plant type, sowing machine, flower blossomizer, , Morphogenesis promotion, control of flower bud differentiation, prevention of pests and diseases, and improvement of sugar content.

On the other hand, in order to grow plants in houses or indoors, in addition to the above-mentioned artificial lighting apparatuses, hot wind or heating apparatuses that maintain the temperature required for the growth of plants are required. In addition, It is necessary to transfer the light evenly to the stem to make it grow well. In particular, in the case of the stem plant, which stores the nutrients in the stem such as the tubule, the straight stem and the winding stem, the stem grows uniformly in the vertical direction or the inclined direction If it is radiated, it will be radiated without shading, and stem plants will grow evenly.

Conventionally, in a plant cultivating luminaire using most LEDs, heat generated from a plurality of LEDs is merely dissipated as waste heat by using various kinds of heat radiating openings or blowing fans, and heat generated from each LED Is not used as the heat required for the growth of the plant, and the heating cost is unnecessarily increased.

In addition, although most of the conventional LED lighting apparatuses can regulate the light intensity and control a part of the wavelength, they can not be applied to stem plants having relatively long stems and many leaves, that is, And an intangible function that can transmit light evenly to the stem, so that it can not radiate light vertically or obliquely to the whole crop, and thus the lightening action of the dioxin can not be blocked, so that the crop can not grow evenly.
