Description

Method for development for plant grow light technology with variation of a specific wave length driven by light emitting diodes}

The present invention is applied to plant growth lamps by utilizing LEDs, and specifically, uses 450 nm and 650 nm lights essential for photosynthesis of plants, as well as targets light that emits green and yellow reinforced emitters in the visible region. It is a technology related to the growth of each crop. First, it is an integrated artificial photosynthesis technology for the correlation between light and growth of plant growth according to the combination of wavelengths. Second, the growth of crops is a plant cultivation technique in which 450 nm of light reacts very sensitively to the total color fraction, and thus growth factors are determined. It is a customized plant growth technology according to the wavelength of the light source.

Securing sunlight essential for photosynthesis is important for developing eco-friendly agricultural technologies. Sunlight at a specific wavelength is directly involved in plant growth and agricultural production. An example is the “Emerson” principle. This principle is known to be an important factor in increasing the photosynthetic yield of light at wavelengths of 680nm and 700nm, which correspond to “red” light. The photosynthesis yield increases even if only light of each wavelength is separately split. The effect of photosynthesis based on this principle is evident when dividing two wavelengths of light at the same time, and it is known that the photosynthesis yield is several times higher than the sum of photosynthetic yields by light of each wavelength. However, even after this effect is known, quantitative research results related to the increase in photosynthetic efficiency by light of a specific wavelength have not been reported.

Recently, it has been observed that the photosynthetic efficiency is increased not only by the light of “red” wavelength showing an emerson effect in a specific plant, but also by the light of a specific wavelength in the “visible ray” region. Although there is a need to develop plant growth, etc. based on quantitative data of photosynthetic effect by this specific wavelength, in reality, it is not only easy to obtain plant growth, etc. that combines specific wavelengths to support these research results. However, there was a limit to finding a large supply.

On the other hand, apart from the demand for the development of plant lamps, the nationwide nation has promoted agricultural productivity and has supplied energy-efficient blue LEDs to farmhouses as a part of plant growth lamp supply. However, it was a situation that had to be satisfied to fill the shortage of sunlight with only the existing blue LED, not a plant-specific plant growth lamp. Accordingly, some domestic and foreign LED companies have focused on photosynthesis and released two-wavelength growth lamps complementing the wavelengths of 450 nm and 650 nm, which are mainly absorbed by chlorophyll (FIG. 1).

In addition, LEDs having reinforced long wavelength 650 nm regions such as plant growth based on chlorophyll absorption have also been released. Recently, an LED lamp reproducing the solar spectrum has been released, and large-scale publicity is underway with high color rendering, and it is marketed as a judgment that it can be applied as a plant lamp (Fig. 1). However, in the case of a high color rendering LED, only the similar solar spectrum is reproduced, and the light-growth correlation of plant growth is not considered at all. In fact, the basic requirement of plant growth lamps used for artificial photosynthesis is that the plant's sensitivity to light is a top priority research subject (FIG. 1).

In the artificial solar design, the absorption spectrum of chlorophyll that responds to light corresponding to the light reaction during photosynthesis of plants is a standard (FIG. 5). In the case of the plant growth luminaire of Fig. 1, which is currently commercially available, it is not possible to generate light under an actual light reaction condition. In addition, in order to promote effective artificial photosynthesis, it is necessary to establish a scientific correlation between sunlight and plant growth. However, in reality, there is a large gap between LED producers and farmers who are growing crops due to insufficient growth results and experiments.

In addition, when the light of the LED is dissociated, it is classified as high-end lighting in the conventional LED lighting as it evolves (FIG. 1). This classification is determined considering the color rendering index and shows a gradual improvement with the addition of a 650 nm wavelength. However, in order to improve the color rendering index, high-cost LEDs have to be used, so economical cost must also be considered. The core of the problem is that even if such a high cost LED with high color rendering is used for plant growth, it is very difficult to expect the corresponding growth efficiency. In other words, the use of plant growth, etc. without identifying the correlation between artificial sunlight and growth conditions is an unacceptable proposal for agricultural production sites. In other words, it becomes a very unrealistic LED light source. In addition, since photosynthetic conditions vary depending on the type of plant, it is difficult to apply it to plant growth in a batch without careful wavelength analysis of the artificial sun.

Hereinafter, the present invention will be described in detail.

The present inventors designed the wavelength of the artificial sun based on the chlorophyll absorption spectrum of FIG. 2. First, in FIG. 1, the absorption of 550 nm and 600 nm is weak, but cannot be neglected unilaterally, and thus, if possible, LEDs showing full-color characteristics are used as a basis. In addition, the absorption of 450 nm is relatively small compared to that of 650 nm, but since it corresponds to high energy in terms of energy, the growth correlation of plants was investigated based on the change in wavelength of 450 nm.

< Example 5> Analysis of the effect on the growth of all beans according to the change of LED wavelength

The length and weight of the whole bean were measured according to the change in the LED wavelength. The length of the above ground was measured daily from 7 days after sowing, and the weight of the whole plant for each POT was measured 20 days after sowing.

Specifically, a total of four types of full-color LED plant lamps (PLED-1.0, PLED-0.75, PLED-0.5, PLED-0.25), commercial LED lamps, and Q2R lamps that tried to adjust the wavelength with quantum tape were used in the laboratory's experimental box. Installed on September 14, 2018 to October 17, 2018, the length of the whole bean was investigated.

As a result, in the case of planting and planting full-color LED plant lamps, the average plant height was much longer than that of commercial LED lamps or Q2R lamps. It was confirmed that the most excellent (Fig. 16).
