최근 들어 식물, 농작물 등을 계절에 관계없이 연중 안정적으로 생산하기 위하여 일정한 시설 내에 빛, 온도와 습도, 이산화탄소 농도, 배양액 등의 환경 조건을 인공적으로 제어하여 계절과 장소에 관계없이 자동적으로 연속 생산하는 시설이 증가하고 있으며, 이를 이른바 식물 공장이라 한다. In recent years, in order to produce plants, crops, etc. regardless of season, year-round, artificially control environmental conditions such as light, temperature and humidity, carbon dioxide concentration, and culture solution in a certain facility to continuously produce regardless of season and place. Increasing facilities are called plant plants.
이와 같은 식물 공장은 인공광원의 제공, 온도와 습도의 조절 등을 위하여 필수적으로 에너지를 사용하여야 하며, 이를 위해 다양한 형태의 에너지원을 사용하고 있다. Such plant factories must use energy for the provision of artificial light sources, for the control of temperature and humidity, and for this purpose, various types of energy sources are used.
일반적으로 사용되는 에너지원은 석탄, 석유, 천연가스 등과 같은 화석 연료 및 핵연료를 이용하는 경우가 대부분이나, 이러한 화석연료는 연소과정에서 발생하는 각종 공해물질로 인하여 환경을 오염시키고, 핵연료는 수질오염 및 방사능과 같은 유해물질을 발생시키는 단점과 함께 이들 에너지원은 매장량의 한계로 인하여 근래에는 이를 대체할 수 있는 신재생 에너지의 개발이 활발하게 진행되고 있다. 신재생 에너지는 풍력, 태양열, 지열, 공기 등 자연에서 무한하게 얻을 수 있으며, 공장에서 버려지는 폐수로부터도 얻을 수 있다. Most commonly used energy sources are fossil fuels such as coal, petroleum, and natural gas, and nuclear fuels. However, these fossil fuels pollute the environment due to various pollutants generated during combustion, and nuclear fuel is used for water pollution and In addition to the disadvantages of generating harmful substances such as radioactivity, due to the limited reserves of these energy sources, in recent years, the development of renewable energy that can replace it is being actively developed. Renewable energy can be infinitely obtained from nature, such as wind, solar, geothermal and air, and from wastewaters that are discarded in factories.
따라서, 식물 재배를 위한 식물 공장 시스템 등에 있어서도 아래 특허문헌과 같은 태양광을 이용한 조명장치를 이용하여 자연광을 제공하거나, 지열을 이용하여 온도의 조절이 가능하도록 하고 있다. 그러나 태양광을 이용하여 식물 공장 내에 일정한 조도를 유지하도록 하는 경우에는 태양광의 입사량이 충분치 않은 흐린 날이 계속되거나 장마철 등의 경우에 충분한 조도를 얻을 수 없으며, 이에 따라 엘이디(LED) 등의 조명장치를 함께 설치하여 조도를 유지할 수 있도록 하고 있다. 그러나 흐린 날이 계속되는 경우에는 엘이디 조명을 지속적으로 사용하여야만 하고, 이를 통한 발열이 매우 심각하였으며, 발명이 계속될 경우 엘이디 등의 조명장치가 쉽게 고장나는 문제가 있었다. Therefore, even in a plant factory system for plant cultivation, it is possible to provide natural light by using an illumination device using solar light as described in the following patent document, or to control temperature using geothermal heat. However, when using sunlight to maintain a constant illuminance in a plant factory, it is impossible to obtain sufficient illuminance in the case of a cloudy day when the amount of incident sunlight is insufficient or in the rainy season, and thus, an illumination device such as an LED. It is installed together to maintain the illuminance. However, if the cloudy day is continued, the LED lighting must be used continuously, and the heat generated through this is very serious, and if the invention continues, there was a problem that the lighting device such as the LED is easily broken.
또한, 지열을 이용하여 냉, 난방을 실시하는 다양한 장치들이 개발되어 출원된바 있으나, 실제로 열손실 등의 문제로 인해 기타 다른 에너지원을 통한 온도의 조절보다 좋은 효율을 보이지 못하고 있다. In addition, various devices for cooling and heating using geothermal heat have been developed and filed, but due to problems such as heat loss, they do not show better efficiency than temperature control through other energy sources.

상기 집광부(11)는 도 1에 도시된 바와 같이 태양으로 방출되는 광이 입사되어, 입사된 광을 집광하는 구성으로, 렌즈, 반사판 등으로 구성되며, 상기 집광부(11)에 의하여 모아진 태양광은 상기 광전송부(12)를 통해 식물재배공간(S) 내의 조명부(13)로 전달된다. 상기 집광부(11)는 기공지된 다양한 방식이 적용될 수 있으며, 이에 관한 상세한 설명은 생략한다. As shown in FIG. 1, the light collecting unit 11 is configured to collect light incident upon the light emitted by the sun, and to collect the incident light. The light collecting unit 11 includes a lens, a reflector, and the like, and is collected by the light collecting unit 11. Light is transmitted to the lighting unit 13 in the plant cultivation space S through the light transmission unit 12. The light collecting part 11 may be applied in various ways, and the detailed description thereof will be omitted.
상기 광전송부(12)는 상기 집광부(11)에 의하여 모아진 태양광을 상기 조명부(13)로 전달하도록 하는 구성으로, 광덕트, 광케이블 등 다양한 방식이 적용될 수 있으며, 광섬유가 다발 형태로 이루어진 광케이블이 적용되어 광손실 없이 다양한 위치로의 광 전달이 가능하도록 하는 것이 바람직하다. The optical transmission unit 12 is configured to transfer the solar light collected by the condensing unit 11 to the lighting unit 13, various methods such as optical ducts, optical cables can be applied, and the optical fiber is made of a bundle of optical fibers It is desirable to apply this to enable light transmission to various locations without light loss.
상기 조명부(13)는 상기 식물재배공간(S)의 상부에 설치되며, 상기 광전송부(12)와 연결되어 상기 광전송부(12)로부터 태양광을 전달받고, 이를 식물재배공간(S) 내부에 발산하도록 한다. 따라서, 상기 광전송부(12)와 연결되는 광섬유가 삽입되는 광파이프(131)를 포함하여 태양광의 발산이 이루어지도록 하고, 태양광에 의한 조도의 제공을 보충하기 위하여 엘이디조명(132) 또한 포함한다. The lighting unit 13 is installed above the plant cultivation space (S), is connected to the light transmission unit 12 receives the sunlight from the light transmission unit 12, this inside the plant cultivation space (S) To diverge. Therefore, including an optical pipe 131 into which the optical fiber connected to the optical transmission unit 12 is inserted, the solar light is diverted, and LED lighting 132 is also included to compensate for the illumination of the sunlight. .
상기 광파이프(131)는 상기 광전송부(12)와 연결되어 내부로 광섬유가 삽입되도록 할 수 있으며, 광섬유의 상부에 구멍을 뚫어 태양광이 상기 광파이프(131) 내부로 발산되도록 하고, 상기 광파이프(131)의 내부에서 태양광을 다시 밑으로 반사시켜 상기 광파이프(131)의 하측으로 태양광이 발산될 수 있도록 한다. 예를 들어 상기 광섬유가 플라스틱 광섬유로 형성되는 경우에는 코어의 표면에 코팅된 클래드를 제거함으로써 코어에서 직접 빛의 외부로 누설되도록 할 수 있고, 클래드가 제거된 광섬유 상부에 반사갓을 씌워 형광등과 같은 태양광 조명을 형성하도록 할 수 있다. 다만 이에 한정되지는 않으며 다양한 태양광 발산 방식이 적용될 수 있다. 그러나 태양광은 환경오염을 일으키지 않으며 자원고갈의 문제가 없으므로, 식물에게 친환경적인 조도(빛)를 제공할 수 있으나, 태양은 흐린 날의 경우에는 충분한 조도를 제공할 수 없고, 특히 장마철 등 흐린 날이 계속되는 경우에는 식물에게 충분한 빛을 제공하지 못하여 식물이 정상적으로 생장하지 못하는 문제가 발생할 수 있다. 따라서, 이를 보충하기 위해 태양광에 의한 조도의 제공이 충분하지 않은 경우 엘이디조명(132)에 의해 조도를 제공하도록 한다. The optical pipe 131 may be connected to the optical transmission unit 12 to allow the optical fiber to be inserted into the optical pipe 131. The optical pipe 131 penetrates an upper portion of the optical fiber to allow sunlight to be emitted into the optical pipe 131. Sunlight is reflected downward again inside the pipe 131 so that the sun light can be emitted to the lower side of the light pipe 131. For example, when the optical fiber is formed of a plastic optical fiber, the clad coated on the surface of the core can be removed so that the core can leak directly to the outside of the light. Light illumination can be formed. However, the present invention is not limited thereto, and various solar light emitting methods may be applied. However, since sunlight does not cause environmental pollution and there is no problem of depletion of resources, it can provide environmentally friendly illumination (light) to plants, but the sun cannot provide sufficient illumination in cloudy days, especially on cloudy days in rainy seasons. In this case, there may be a problem that plants do not grow normally because they do not provide enough light to the plants. Therefore, to compensate for this, if the illumination by the sunlight is not sufficient to provide the illumination by the LED lighting (132).

Therefore, the illumination intensity by sunlight by the light quantity measurement module 151 to be described later of the control unit 15, LED lighting 132 by the operation module 152 to be described later only when the illumination intensity does not reach the set value This should work. However, in case of rainy season in which the cloudy day continues, since the illumination of sunlight is not smoothly provided, the LED lighting 132 needs to operate for a long time, and heat is generated accordingly. Therefore, when the cloudy day continues or the illumination is not provided by the solar light due to other causes, the risk of failure or fire of the lighting unit 13 due to the heat generated by the long time operation of the LED lighting 132.
