Description

광섬유를 이용한 태양 집광 시스템{Lightning System Using optical Fiber and Solar Reflector}BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to an optical fiber,

광섬유, 조명, 오목거울.Optical fiber, lighting, concave mirror.

태양빛은 인간과 동식물에게 있어서 성장 및 생활을 유지하는데 중요한 요소이다. Solar light is an important factor in maintaining growth and life for humans, plants and animals.

태양광을 이용한 자연채광 방식은 주로 천장이나 건물 외부창 근처에서 루버, 반사판, 광덕트, 광섬유 등을 이용하여 실내로 태양광을 전송하는 방식이다. The natural daylighting method using sunlight is a method of transmitting sunlight to the room by using louvers, reflectors, optical ducts, optical fibers, etc. in the vicinity of a ceiling or a building exterior window.

전송된 태양빛에 의한 조명은 전기에너지의 절약 뿐 아니라, 인간의 건강을 활성화하거나, 동식물의 생육 및 성장에 적당한 환경을 조성한다.Illumination by transmitted sunlight not only saves electrical energy, but also promotes human health and creates an environment suitable for the growth and growth of plants and animals.

광섬유는 광섬유를 여러 가닥 묶어서 케이블로 만든 것을 광케이블이라고 하며, 그 사용이 늘어나고 있다. 광섬유는 합성수지를 재료로 하는 것도 있으나, 주로 투명도가 좋은 유리로 만들어진다. 구조는 보통 중앙의 코어(core)라고 하는 부분을 주변에서 클래딩(cladding)이라고 하는 부분이 감싸고 있는 이중원기둥 모양을 하고 있다. 그 외부에는 충격으로부터 보호하기 위해 합성수지 피복을 1～2차례 입힌다.Fiber optic cable is made by bundling several strands of optical fiber, called optical cable, and its use is increasing. Optical fibers are made of synthetic resin, but they are mainly made of glass with good transparency. The structure usually has a double cylindrical shape in which a portion called a core is surrounded by a portion called a cladding. The outside is covered with synthetic resin cloth one or two times to protect it from impact.

보호피복을 제외한 전체 크기는 지름 백～수백마이크로 미터로 되고, 코어 부분의 굴절률이 클래딩의 굴절률보다 높게 되어 있어서, 빛이 코어 부분에 집속되어 잘 빠져나가지 않고 진행할 수 있게 되어 있다.The total size of the protective layer is 100 to 100 micrometers in diameter. The refractive index of the core portion is higher than the refractive index of the cladding, so that the light is focused on the core portion and can proceed without escape.

코어의 지름이 수 마이크로 미터인 것을 단일모드 광섬유, 수십 마이크로미터 인 것을 다중모드 광섬유라 하고, 코어의 굴절률 분포에 따라 계단형 언덕형 광섬유 등으로 나눈다. 광섬유는 외부의 전자파에 의한 간섭이나 혼선이 없고 도청이 힘들며, 소형 경량으로서 굴곡에도 강하며, 하나의 광섬유에 많은 통신회선을 수용할 수 있고 외부환경의 변화에도 강하다. 더구나 재료인 유리의 원료는 대단히 풍부하므로 효용도가 높다. 빛의 손실을 최소화하여 멀리 보내기 위해 사용되는 것이다.A multimode optical fiber having a diameter of several micrometers is called a single mode optical fiber and a multimode optical fiber having a diameter of several tens of micrometers is divided into a stepped hill type optical fiber according to the refractive index distribution of the core. The optical fiber has no interference or confusion by external electromagnetic waves, is difficult to tear, is light in weight and strong in bending, accommodates a large number of communication lines in one optical fiber, and is resistant to changes in the external environment. Moreover, the raw material of the glass, which is a material, is very abundant, and thus the utility is high. It is used to minimize the loss of light and to send it away.

빛은 직진성 때문에 직선으로 나가는데 직진하다가 앞에 장애물(건물이나 수증기 등등)이 있으면 흡수되거나 반사, 산란되어 원하는 방향으로 멀리 보내기가 힘들다. 광섬유를 이용하면 빛이 광섬유 안에 갇혀서 광섬유가 휘어져 있으면 휘어져 있는 대로 빛이 광섬유를 따라 이동하게 된다. 즉 빛을 원하는 곳으로 멀리 보낼 수 있다. 이를 전반사라고 볼 수 있는데 정확한 설명은 입사각이 임계각에 도달하는 순간 100% 굴절 없이 반사가 일어나는 현상을 말한다. 이 원리는 스넬의 굴절법칙에 의하여 n(air)*sinx= n(유리)* sinx유리 (n은 굴절율) 여기서 유리의 sin90 을 대입해서 풀면 임계각을 계산할 수 있다. 이 경우 x는 41.8도 일반적으로 굴절률이 높을 수 록 임계각은 낮으므로 굴절률이 높은 물질과 쉽게 구부러질 수 있는 성질을 가진 액체를 플라스틱관에 담아 사용하면 좋은 광섬유 대용 재료로 활용할 수 있다.Light travels in a straight line because of its straightness, and if there are obstacles (buildings, water vapor, etc.) in front of it, it is absorbed, reflected and scattered and it is difficult to send away in a desired direction. Using optical fiber, light is trapped in an optical fiber, and if the optical fiber is bent, the light travels along the optical fiber as it is bent. In other words, you can send the light away to where you want. This can be regarded as a total reflection. The exact explanation is a phenomenon where reflection occurs without refraction at 100% when the incident angle reaches the critical angle. This principle is based on Snell's law of refraction n (air) * sinx = n (free) * sinx glass (where n is the refractive index) In this case, x is 41.8 degrees. Generally, the higher the refractive index, the lower the critical angle. Therefore, a material having a high refractive index and a property capable of bending easily can be used as a substitute material for a good optical fiber in a plastic tube.

본 발명은 분산되어 지구에 도달하는 태양광을 광섬유를 통해 저비용 고효율로 집광할 수 있는 장치를 만든다.The present invention provides an apparatus that can disperse sunlight reaching the earth at a low cost and high efficiency through an optical fiber.

본 발명을 구현하기 위해서는 포물선과 쌍곡선의 원리를 이용하여 반사경을 만든 다음 이렇게 집광된 센빛을 광섬유나 구부러지기 쉬운 파이프에 굴절율이 큰 액체를 채워서 빛이 채광이 않되는 장소에 도달하도록 한다. .In order to realize the present invention, a reflector is made using the parabolic and hyperbolic principles, and then the condensed green light is filled in the optical fiber or the pipe which is liable to bend, so that the light reaches the place where the light is not refracted. .

태양광을 직접 이용함으로써 비용없이 조명으로 이용할 수 있어 에너지를 절감하고 에너지 사용료를 절약할 수 있고 집광하여 사용함으로써 효율을 극대화할 수 있다. By directly using sunlight, it can be used as lighting without cost, saving energy, saving energy cost, and maximizing efficiency by using condensed light.

도 1은 본 발명의 태양광 집광을 위한 포물 반사경 1 is a schematic view of a parabolic reflector

본 발명의 구조는 모든 방향에서의 단면이 포물선으로 이루어진 포물반사경(1-1, 2-1)과 쌍곡선면 반사경(1-4, 2-4)을 쌍곡선면 반사경 지지대(1-5, 2-5)로 그 포물선의 촛점에 위치하게 하였고 포물반사경(1-1, 2-1)의 중심에는 광섬유(1-3, 2-3)로 이어진 집광렌즈(1-2, 2-2)를 둔다. 태양과 집광의 원리는 다음과 같다. 태양광이 포물반사경(1-1, 2-1)에 도달하면 태양광은 포물선의 촛점인 쌍곡선면 반사경(1-4, 2-4)에 모아진다. 모아진 태양광은 다시 쌍곡선면 반사경(1-4, 2-4)에서 반사되어 원점인 포물반사경(1-1, 2-1)의 중심으로 향하여 집광렌즈(1-2, 2-2)에 모아지고 광섬유(1-3, 2-3)를 통하여 원하는 곳으로 이동시킬 수 있다. The structure of the present invention is characterized in that the parabolic reflectors 1-1 and 2-1 and the hyperbolic plane reflectors 1-4 and 2-4 each having a parabolic cross section in all directions are placed on the hyperbolic reflector supports 1-5, 5, and the condenser lenses 1-2 and 2-2 connected to the optical fibers 1-3 and 2-3 are placed at the center of the parabolic reflectors 1-1 and 2-1 . The principle of the sun and condensation is as follows. When the sunlight reaches the parabolic reflectors 1-1 and 2-1, the sunlight is collected in the hyperbolic surface reflectors 1-4 and 2-4, which are the focus of the parabola. The collected sunlight is again reflected by the hyperboloidal surface reflectors 1-4 and 2-4 and collected in the condenser lenses 1-2 and 2-2 toward the centers of the parabolic reflectors 1-1 and 2-1 as the origin And can be moved to a desired position through the optical fibers (1-3, 2-3).
