식물성장용 인공태양광 장치{ A artificial sunlight system for plant growth}Artificial sunlight system for plant growth

인공 광원을 식물재배에 응용하는 기술은 국화꽃의 개화시기를 조절하는 등 시설원예 분야에서 많이 응용되고 있다. 1869년 러시아 과학자 K. A. Timiryazev 등은 광 스펙트럼이 시설하우스 내의 식물성장에 크게 영향을 미친다는 것을 발견하였다. 즉, 오렌지-레드(590-700nm) 또는 블루(420-470nm) 광이 식물의 수확량을 크게 증가시킨다는 것을 알아냈다. 식물성장 환경에 있어서 인공조명은 사계절의 변화나 비, 눈 등의 날씨 변화에 관계없이 일정한 수확량을 보장할 수 있는 장점이 있다. The application of artificial light sources to plant cultivation has been widely applied in the field of horticulture, such as controlling the flowering time of chrysanthemum flowers. In 1869, the Russian scientist K. A. Timiryazev et al. Found that the light spectrum greatly influenced the growth of plants in facility houses. That is, it was found that orange-red (590-700 nm) or blue (420-470 nm) light greatly increased the yield of the plant. Artificial lighting has the advantage of guaranteeing a constant yield regardless of changes in the four seasons or weather changes such as rain and snow.

자연의 태양광이 충분치 못할 때, 인공 광원을 식물의 성장에 이용하는데, 인공 광원으로서 백열전구는 수명과 전력 소모량이 크게 줄어든 할로겐등(3)으로 대체하고 있다. 특히, 할로겐등(3)은 황색의 스펙트럼이 강하게 나타나는 특성이 있어 식물의 성장에 유리한 광원이다. 메탈 할라이드등(2)은 형광등과 같이 방전에 따른 메탈 발광체에 의한 광으로 수명이나 전력 소모에 있어서 형광등보다 유리하며 청색 스텍트럼의 특성이 좋아 식물 성장에 유리한 광원이다. LED 광원(5)은 청 색 또는 적색의 다양한 광원이 존재하고, 전력소모 또한 적어 인공 광원으로서 가치가 있다. 단지, LED광원(5)은 아직 발광량에 비하여 다소 비싸다는 점이 지적되고 있다. 식물 성장을 위한 인공 태양광 장치로서는 소비전력이 작으면서 충분한 발광량 그리고 식물 성장에 유익하다는 광 스펙트럼 특성이 좋은 광원을 필요로 하고 있다.When natural sunlight is not enough, an artificial light source is used for plant growth. As an artificial light source, an incandescent lamp is replaced by a halogen lamp (3) which has greatly reduced its lifespan and power consumption. In particular, the halogen lamp 3 is a light source that is advantageous for plant growth because of its strong yellow spectrum. The metal halide lamp 2 is a light source that emits light by a metal light emitting body due to a discharge, such as a fluorescent lamp, which is advantageous over fluorescent lamps in terms of life and power consumption, and has a good blue spectrum, which is advantageous for plant growth. The LED light source 5 has various light sources of blue or red, and also has low power consumption, which is valuable as an artificial light source. However, it is pointed out that the LED light source 5 is still somewhat expensive compared to the light emission amount. As an artificial photovoltaic device for plant growth, there is a need for a light source having low power consumption and sufficient light emission characteristics and good light spectral characteristics that are beneficial for plant growth.

식물성장 환경에 있어서 사계절의 변화나 비, 눈, 구름 등의 날씨 변화에 따라 일정한 수확량을 보장할 수 없는 문제점이 있다. 식물의 성장을 위한 인공조명으로는 소비전력이 작고, 수명은 길면서 충분한 광량을 만들 수 있어야 한다. 최근 할로겐등(3)이나 메탈 램프와 같은 새로운 광원이 나타남에 따라 기존의 백열전구나 형광등을 수명이나 소비전력 면에서 투자비용이 높을 수밖에 없다. led 등(5)은 청색 및 적색 파장을 용이하게 만들 수는 있으나 광량이 충분치 못한 것이 투자비를 늘리는 원인이 된다. 적은 투자비와 유지 비용으로 충분한 광량을 만들 수 있는 광원을 선택하되, 식물의 성장을 제어할 수 있는 청색과 적색의 광량 비율 즉, B/R 값을 제어할 수 있는 조명 시스템이 필요한 것이다. [도 4]In the plant growth environment, there is a problem in that it is not possible to guarantee a constant yield due to changes in the four seasons or weather changes such as rain, snow, and clouds. Artificial lighting for plant growth requires low power consumption, long lifespan, and sufficient light output. As new light sources such as halogen lamps (3) and metal lamps appear recently, investment costs for incandescent lamps and fluorescent lamps are high in terms of lifespan and power consumption. The led lamp 5 can easily make the blue and red wavelengths, but the insufficient amount of light causes an increase in the investment cost. You need to choose a light source that can produce enough light at a low investment and maintenance cost, but you need a lighting system that can control the ratio of blue and red light, or B / R, to control plant growth. [Figure 4]

본 발명에서 인공조명등은 형광등이나 백열전구보다 수명이 길고 소비전력이 크지 않으면서 충분한 광량을 주는 메탈할라이드등(2)과 할로겐등(3)을 채택하였다. 특히, 메탈할라이드등(2)은 청색 파장이 발달한 광이고, 할로겐등(3)은 적색 파장이 발달한 광이어서 두 조명의 조화가 식물의 성장에 필요한 파장 대를 효과적으로 지원하게 된다. 식물에 따라서는 청색과 적색의 광량 비를 조절할 필요가 있는데, 이는 식물에 도달하기 전에 파장 선별 코팅렌즈를 통과하게 함으로서 일정부분 조절이 가능하며, 나아가 외부에 부착된 청색 및 적색 led 등(5)을 점멸함으로 서도 최종 조절이 가능하다.In the present invention, the artificial light is longer than the fluorescent lamps or incandescent bulbs, and adopts a metal halide lamp (2) and a halogen lamp (3) that give a sufficient amount of light without large power consumption. In particular, the metal halide lamp (2) is a light with a developed blue wavelength, the halogen lamp (3) is a light with a developed red wavelength, so that the harmony of the two lights to effectively support the wavelength band required for plant growth. Depending on the plant, it is necessary to adjust the ratio of light to blue and red, which can be partially adjusted by passing the wavelength selective coating lens before reaching the plant, and furthermore, blue and red led lamps attached to the outside (5). The final adjustment is also possible by blinking.

본 발명에서 청색 파장이 발달한 메탈할라이드광은 식물의 광합성에 유리하고, 적색 파장이 발달한 할로겐광은 식물의 개화에 영향을 주어서, 두 조명의 조화가 식물의 성장에 유리하다. 또한, 저렴한 전력소모에도 불구하고 광량이 충분하여 대면적의 식물 재배에 효과적으로 대응이 가능하다. 이들 광원이 파장 선별 코팅렌즈(6)를 통과함으로써 식물에 따른 적절한 청색 및 적색 파장의 광량을 조절할 수 있고, 외부의 led등(5)에 의하여 청색 및 적색 파장 대의 광량을 최종적으로 조율하게 된다. 광 케이블(1)로 들어오는 자연광은 식물의 건강한 성장에 도움이 된다. [도 1]In the present invention, the metal halide light having a developed blue wavelength is advantageous to photosynthesis of the plant, and the halogen light having a developed red wavelength affects the flowering of the plant, so that the harmony of the two illuminations is advantageous for the growth of the plant. In addition, despite the low power consumption, the amount of light is sufficient to effectively cope with the large-scale plant cultivation. By passing these light sources through the wavelength selective coating lens 6, the amount of light of appropriate blue and red wavelengths according to plants can be adjusted, and the amount of light in the blue and red wavelength bands is finally tuned by the external led lamp 5. Natural light entering the optical cable 1 helps the healthy growth of the plant. 1

본 발명의 장치에서 조명용 광원으로 광케이블의 자연 광원(4), 할로겐 광원(3), 메탈할라이드광원(2) 및 led 광원(5)을 사용하고, 광케이블의 자연 광원(4), 할로겐 광원(3), 메탈할라이드 광원(2)은 식물에 도달하기 전에 파장 선별 코팅 렌즈(6)를 통과하도록 하였다. 코팅 렌즈(6) 내부의 할로겐등(3)과 메탈할라이드등(2)은 전력소모에 비하여 충분한 광량을 생산할 수 있고, 외부의 청색 및 적색 led 등(5)은 광량은 적지만 청색과 적색의 파장의 스펙트럼 비율을 조절하기에 유리하다. [도 1, 도 2] 코팅 렌즈(6)를 통과하기 전의 광원들의 스펙트럼 분포를 보면 전체 파장에 대하여 연속적이며 고르게 분포하고 있다. [도 3] 코팅 렌즈(6)를 통과한 후 스펙트럼 분포를 보면 청색과 적색영역만 뚜렷하게 통과하고 있다. 또한, 청색과 적색의 광량도 일정하게 제어하게 된다. 식물에 따라서 청색 광과 적색 광의 비율 즉, B/R 값을 제어할 필요가 있을 경우 코팅 렌즈(6)에서 제어하거나 외부에 장착된 청색 및 적색 led등(5)의 점멸을 조절하여 그 비율을 만들 수 있도록 한다. [도 4] 자연광은 식물의 건강한 성장에 보이지 않는 영향을 미치고 있어, 태양이 떠 있는 일 중에는 광섬유 케이블(1)을 통하여 가져오게 한다. In the device of the present invention, a natural light source (4), a halogen light source (3), a metal halide light source (2) and a led light source (5) of an optical cable are used as a light source for illumination, and the natural light source (4) and a halogen light source (3) of an optical cable are used. ), The metal halide light source 2 was allowed to pass through the wavelength selective coating lens 6 before reaching the plant. The halogen lamp 3 and the metal halide lamp 2 inside the coating lens 6 can produce a sufficient amount of light compared to the power consumption. The external blue and red led lamps 5 have a small amount of light but are blue and red. It is advantageous to adjust the spectral ratio of the wavelength. 1 and 2 The spectral distribution of the light sources before passing through the coated lens 6 is continuously and evenly distributed over the entire wavelength. FIG. 3 shows the spectral distribution after passing through the coating lens 6, and clearly passes only the blue and red regions. In addition, the amount of blue and red light is also controlled constantly. Depending on the plant, if it is necessary to control the ratio of the blue light and the red light, that is, the B / R value, the ratio is controlled by controlling the coating lens 6 or controlling the blinking of the externally mounted blue and red led lamps 5. Make it work. Fig. 4 has invisible effects on the healthy growth of plants, which are brought in through the optical fiber cable 1 during the sun's floating day.
