Description

태양조명시스템의 냉각장치{COLLING APPARATUS FOR SUN LIGHTING SYSTEM}Cooling system of solar lighting system {COLLING APPARATUS FOR SUN LIGHTING SYSTEM}

본 발명은 태양광 집광설비 시스템에 관한 것으로서, 특히 채광부의 후란넬 렌즈에서 집광된 고밀도의 태양광이 열선차단 IR 코팅 유리막대 렌즈를 통해 광섬유케이블에 전달됨으로서 광섬유케이블에 고온의 열이 발생되는 것을 방지하고, 상기 열선차단 IR 코팅 유리막대에서 발생되는 열을 냉각팬을 통해 냉각해주는 태양조명 시스템의 냉각장치에 관한 것이다.The present invention relates to a solar light collecting system, and particularly, that high-density solar light collected from a flannel lens of a mining part is transmitted to an optical fiber cable through a heat-shielding IR-coated glass rod lens to generate high temperature heat in the optical fiber cable. The present invention relates to a cooling device of a solar lighting system that prevents and cools heat generated by the heat shielding IR coated glass rod through a cooling fan.

일반적으로 태양광은 인간의 눈에 밝기를 느끼게 하는 약 0.38~0.78㎛의 파장을 갖는 가시광선과, 0.38㎛ 이하의 파장을 갖는 자외선과, 0.78㎛이상의 파장을 갖는 적외선으로 이루어져 있으며, 태양광이 자연스럽고 건강적인 조명효과, 온열효과, 건강효과 및 질환치료에 유용한 보건 효과등으로 인해 우리의 생활에 매우 유익하다는 것은 이미 잘 알려진 사실이다.In general, sunlight is composed of visible light having a wavelength of about 0.38 ~ 0.78㎛ to make the human eye feel the brightness, ultraviolet light having a wavelength of less than 0.38㎛, infrared light having a wavelength of more than 0.78㎛, sunlight is natural It is well-known that it is very beneficial to our lives because of the light and healthy lighting effects, the thermal effects, the health effects and the health effects useful for the treatment of diseases.

그러나 현대에는 산업화가 이루어져 실내에서 생활하거나 활동하는 시간이 상대적으로 많아지게 되고, 대부분의 건축물이 자연적이 아닌 인공적인 환경에서 생활하도록 건축되기 때문에 인공조명으로 필요한 밝기를 확보하고자 하는 경향이 현저한 실정이다. 그러므로 고층아파트나 빌딩의 사무실에서 일과 휴식을 위한 공간을 확보하고 필요에 따라 태양의 빛과 초목의 푸르름 같은 자연적인 것을 적극적으로 조화시켜 인간을 위주로 한 건강한 환경을 창출하고자 하는 움직임이 점차 강해지고 있다.In modern times, however, the industrialization has led to a relatively large amount of time for living and working indoors, and since most buildings are built to live in an artificial environment instead of a natural environment, there is a tendency to secure necessary brightness with artificial lighting. . Therefore, the movement to secure a space for work and rest in high-rise apartments or office buildings, and to actively create natural environments such as human beings by actively harmonizing natural things such as the sun's light and the greenery of vegetation, is becoming stronger. .

따라서 태양광 채광시스템과 일조 확보수단을 구비하여 실내나 지하에서 자연 그대로의 환경을 향유할 수 있으며, 실내공간에서도 사시사철 초목이 아름답게 꾸며져 있도록 하였다.Therefore, it is possible to enjoy the natural environment indoors or underground by providing solar light system and sunshine securing means.

즉, 태양광 추적장치로 태양광의 방향을 추적하여 경면제어장치로 태양광의 이동에 따라 반사경의 경면기울기를 변화시킨후 다수의 반사율이 높은 거울을 이용하여 상기의 반사경에 반사된 태양광을 원하는 위치에 까지 보내도록 한 반사경 방식을 이용하거나, 태양광 집광장치로 태양광을 수집하여 내부가 반사율이 높은 거울면으로 이루어진 스테레스 튜브나 금속제 덕트인 광덕트를 이용하여 밀폐된 공간으로 빛을 전달하도록 한 광 덕트 방식을 이용하였었다.That is, the solar tracking device tracks the direction of sunlight and changes the mirror slope of the reflector according to the movement of sunlight with a mirror control device, and then uses the mirrors having a high reflectance to position the sunlight reflected by the reflector. It uses a reflector method to send the light to a light source, or collects sunlight with a solar light concentrator and transmits the light to a confined space by using a stainless steel tube made of mirror surface with high reflectivity or a light duct that is a metal duct. One light duct system was used.

그러나 상기와 같은 종래의 반사경 방식은 구조가 간단하여 시공이 간편하고 제조원가가 저렴한 장점이 있는 반면에 사용범위가 좁은 단점이 있으며, 광 덕트 방식은 채광거리가 실내나 지하의 근거리에 제한되는 단점으로 인해 널리 이용되지못하였다.However, the conventional reflector method as described above has the advantage that the construction is simple and the manufacturing cost is low, while the use range is narrow, and the light duct method has a disadvantage that the mining distance is limited to the indoor or underground short distance. It was not widely used.

근래에 개발된 새로운 방법이 광섬유를 이용한 태양광 전송시스템이다. 상기광섬유를 이용한 태양광 전송시스템은 태양위치 검출센서로 검출한 태양의 위치에 따라 구동부의 수직, 수평용 모터로써 위치를 제어하는 다수의 채광부와, 태양광의 조도를 측정하여 일조상태를 인식하는 조도센서와, 상기의 채광부들과 조도센서로 부터 태양위치 및 일조상태에 따른 정보를 입력받아 태양광 추적과 채광의 동작을자체 제어하는 콘트롤러와, 상기 다수의 광부에서 수집된 태양광을 원하는 장소까지 광케이블에 의해 전달하는 전송부로 구성되어, 태양광을 집광하여 광섬유케이블로 전송함으로써 전송효율을 극대화하였다.A new method developed recently is a solar transmission system using optical fibers. The photovoltaic transmission system using the optical fiber is a plurality of mining unit for controlling the position by the vertical and horizontal motor of the driving unit according to the position of the sun detected by the solar position detection sensor, and to measure the illumination of the sunlight to recognize the sunlight condition Controller for controlling the operation of sunlight tracking and light by receiving information from the light sensor, the light units and the light sensor according to the sun position and sunlight conditions, and a place where the light collected from the plurality of light units is desired. Consists of a transmission unit to transmit by the optical cable to maximize the transmission efficiency by condensing the sunlight and transmitted to the optical fiber cable.

상기 광섬유는 빛의 전송을 목적으로 하는 섬유 모양의 도파관으로서, 광학섬유라고도 한다. 광섬유를 여러 가닥 묶어서 케이블로 만든 것을 광케이블이라고 하며, 그 사용이 점차 늘어나고 있다. 광섬유는 빛을 전송하는 코아(Core)와 코아를 둘러싸고 있는 크래드(Clad), 그리고 외부환경으로부터 광섬유를 보호하기 위한 피복층으로 구성되어 있다. 피복층을 제외한 전체 크기는 지름 백 ∼ 수백 ㎛정도 이고, 코어 부분의 굴절률이 크래드의 굴절률보다 높게 되어 있어서, 빛이 코어 부분에 집속되어 잘 빠져나가지 않고 진행할 수 있게 되어 있다. 코어의 지름이 수 ㎛인 것을 단일모드 광섬유, 수십 ㎛인 것을 다중모드 광섬유라고 하고, 코어의 굴절률 분표에 따라 계단형, 언덕형 광섬유 등으로 나눈다. 광섬유는 외부의 전자파에 의한 간섭이나 혼신이 없고 도청이 힘들며, 소형 경량으로서 굴곡에도 강하며, 하나의 광섬유에 많은 통신회선을 수용할 수 있고 외부환경의 변화에도 강하다.The optical fiber is a fibrous waveguide for the purpose of transmitting light and is also called an optical fiber. Fibers are made of a bundle of fibers that are bundled together to form a cable, and its use is growing. The fiber consists of a core that transmits light, a clad that surrounds the core, and a coating layer to protect the fiber from the external environment. The total size excluding the coating layer is about 100-hundreds of micrometers in diameter, and the refractive index of the core portion is higher than the refractive index of the clad, so that light can be focused on the core portion and proceed without exiting well. Cores having a diameter of several micrometers are called single-mode optical fibers, and those having tens of micrometers are called multimode optical fibers, and are divided into stepped and hill-shaped optical fibers according to the index of refraction of the core. Optical fiber has no interference or interference by external electromagnetic waves, it is hard to tap, small size, light weight, strong in bending, can accommodate many communication lines in one optical fiber, and strong in change of external environment.

그러나, 상기 광섬유를 이용한 태양광 전송시스템은 태양광이 후란넬 렌즈를 통해 집광되어 광섬유케이블에 전송되면 상기 광섬유케이블의 전송부위에 500℃ 이상 고온의 열이 발생되므로, 광섬유케이블 시공시 내열특성을 갖는 실리카 광섬유케이블을 사용할 수 밖에 없게되어 시설비용이 과다하게 소요되는 문제점이 있었다.However, in the solar transmission system using the optical fiber, when the sunlight is collected through the flannel lens and transmitted to the optical fiber cable, heat is generated at a high temperature of 500 ° C. or higher at the transmission part of the optical fiber cable. There was a problem in that the facility cost is excessive because the silica fiber cable has no choice but to use.

본 발명은 상기와 같은 문제점을 해결하기 위해 안출된 것으로서, 후란넬 렌즈에서 집광된 태양광을 일차적으로 열선차단 IR 코팅 유리막대 렌즈를 거쳐 광섬유케이블에 전송하고, 열선차단 IR 코팅 유리막대 렌즈의 일측 소정부위에 냉각팬을 설치하여 흡입구를 통해 흡입된 외부의 찬공기를 이용하여 유리막대 렌즈를 냉각시키고, 뜨거워진 공기를 배출구를 통해 외부로 배출시키는 태양조명 시스템의 냉각장치를 제공함에 그 목적이 있다.The present invention has been made to solve the above problems, and primarily transmits the solar light collected from the flannel lens to the optical fiber cable through the heat shield IR coating glass rod lens, one side of the heat shield IR coating glass rod lens The purpose of the present invention is to provide a cooling device of a solar lighting system in which a cooling fan is installed at a predetermined portion to cool the glass rod lens using external cold air sucked through the inlet, and exhaust the hot air to the outside through the outlet. have.

이하에서 첨부된 도면에 의해 본 발명을 상세히 설명한다.Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

도 1에 도시된 바와 같이 태양조명시스템은 다수의 태양광 집광렌즈로 구성되어 있으며 태양위치를 추적하면서 최대량의 태양광을 채집하는 채광부(10)와, 상기 채광부(10)의 근접위치에서 태양의 위치를 측정하는 태양이동감시 광센서(20)와, 상기 채광부(10) 및 태양이동감시 광센서(20)로 부터 태양의 위치에 따른 정보를 입력받아 태양광 추적과 집광의 동작을 자체 수행하는 마이크로 컴퓨터(30)와, 태양광의 궤도를 수직각 및 수평방위로 분석하며 마이크로 컴퓨터의 제어에 따라 채광부(10)의 위치를 자동적으로 조절하는 추적제어기구(40)와, 상기 채광부와 추적제어기구를 외부의 이물질로부터 보호해주는 아크릴 돔(50)과, 상기의 채광부(10)에서 수집된 태양광을 원하는 장소까지 광섬유케이블(61)에 의해 전달하는 전송부(60)와, 상기의 전송부(60)를 통하여 전달된 태양광을 임의의 방향으로 비추어 주는 산광부(70)로 구성되어 있다.As shown in FIG. 1, the solar lighting system is composed of a plurality of solar condenser lenses, and collects the maximum amount of sunlight while tracking the position of the sun, and at a position close to the miner 10. The solar tracking and light concentrating sensor 20 measures the position of the sun and receives the information according to the position of the sun from the mining unit 10 and the solar monitoring light sensor 20 and performs the operation of tracking and condensing the sun. The microcomputer 30 which performs the self, the tracking control mechanism 40 which analyzes the trajectory of sunlight by a vertical angle and a horizontal direction, and automatically adjusts the position of the mining part 10 according to the control of a microcomputer, and the said light Acrylic dome 50 to protect the part and the tracking control mechanism from external foreign matter, and the transmission unit 60 for transmitting the solar light collected by the mining unit 10 to the desired place by the optical fiber cable 61 and , Through the transmission unit 60 above The W passed sunlight is composed of a mountain portion 70 to the light in any direction.

도 2에 도시된 바와 같이 상기 채광부(10)는 태양광 집광렌즈로 사용되는 고순도 아크릴 재질의 후란넬 렌즈(11)가 다수개 구성되어 있으므로 태양광을 고밀도로 집광하며, 상기 태양이동감시 광센서(20)에서는 수직 또는 수평방향으로 태양의 이동에 따른 위치를 검출하는 4개의 광센서를 사용하고, 상기 마이크로컴퓨터(30)에서는 태양이동감시 광센서(20)에서 검출된 태양광의 위치를 전달받아 태양광 집광렌즈와 태양광의 조사방향이 수직을 유지하도록 추적제어기구(40)를 통해 구동모터(도시되지 않음)를 작동시키면서 채광부(10)의 후란넬 렌즈(11)에 최대량의 태양광이 채집되도록 한다.As shown in FIG. 2, since the skylight unit 10 includes a plurality of high-purity acrylic flannel lenses 11 used as a solar condenser lens, the light condenser condenses sunlight at a high density. The sensor 20 uses four optical sensors for detecting the position according to the movement of the sun in the vertical or horizontal direction, and the microcomputer 30 transmits the position of the sunlight detected by the solar motion monitoring optical sensor 20. The maximum amount of sunlight is directed to the flannel lens 11 of the mining section 10 while operating a driving motor (not shown) through the tracking control mechanism 40 so that the irradiation direction of the solar condenser lens and the sunlight is perpendicular to each other. Let this be collected.

또한, 도 3에 도시된 바와 같이 채광부(10)의 후란넬 렌즈(11)에서 고밀도화하여 채광된 태양광은 전송부(60)의 광섬유케이블(61) 전면부에 밀착되는 열선차단 IR 코팅 유리막대 렌즈(12)에 전달되는데, 상기 열선차단 IR 코팅 유리막대렌즈(12)는 인체에 해로운 자외선 및 적외선을 차단하고 가시광선만을 광섬유케이블(61)에 전달하며, 태양광이 직접 조사될 때 발생되는 고온의 열을 견딜 수 있는 내열특성을 가지고 있고, 빛이 전달되는 부위가 오목렌즈를 형성하고 있으므로 광의 입사각도가 중심축으로부터 작게 형성되어 상기 열선차단 IR 코팅 유리막대 렌즈(12)에 입사된 태양광은 전반사되어 광섬유케이블(61)로 전달되어 입사의 효율성이 증대되는 집광의 효과가 나타난다.In addition, as shown in FIG. 3, the solar light which has been densified by the high-density flannel lens 11 of the mining part 10 is in close contact with the front surface of the optical fiber cable 61 of the transmitting part 60. It is transmitted to the rod lens 12, the heat-blocking IR coated glass rod lens 12 blocks ultraviolet rays and infrared rays harmful to the human body and transmits only visible light to the optical fiber cable 61, and occurs when the sunlight is directly irradiated It has a heat-resistant property that can withstand the heat of high temperature, and since the portion to which light is transmitted forms a concave lens, the incident angle of light is made small from the central axis, which is incident on the heat-blocking IR-coated glass rod lens 12. The solar light is totally reflected and transferred to the optical fiber cable 61, so that the effect of condensation of the incident efficiency is increased.

한편, 도 2 및 도 3에 도시된 바와 같이 채광부(10)에 구비된 열선차단 IR 코팅 유리막대 렌즈(12)와 광섬유케이블(61)는 고온에 의해 광섬유케이블(61)이 손상되지 않도록 약간의 거리을 두고 이격되어 있으며, 상기 이격된 부위에는 냉각팬(13)이 설치되어 있으므로 흡입구(15)를 통해 흡입된 외부의 찬공기는 열선차단 IR 코팅 유리막대 렌즈(12)에 발생된 고온의 열을 냉각한 후 배출구(16)를 통해 배출되며, 상기 열선차단 IR 코팅 유리막대 렌즈(12)에 의해 태양광을 공급받는 광섬유케이블(61)에는 직접적인 고온이 전달되지 않는다.Meanwhile, as shown in FIGS. 2 and 3, the heat shielding IR coated glass rod lens 12 and the optical fiber cable 61 provided in the light mining part 10 are slightly damaged so that the optical fiber cable 61 is not damaged by high temperature. Spaced apart from each other, and the cooling fan 13 is installed at the spaced apart portion, so that the cold air sucked out through the inlet 15 is heated at a high temperature of the heat-blocking IR-coated glass rod lens 12. After cooling it is discharged through the outlet 16, a direct high temperature is not transmitted to the optical fiber cable 61 which is supplied with sunlight by the heat-shielding IR coated glass rod lens 12.

따라서, 본 발명에 의한 태양광 조명시스템은 광섬유케이블(61)로 내열특성을 갖는 고가의 실리카 광섬유를 사용하지 않고, 저가의 고순도 아크릴 재질의 광섬유케이블을 사용할 수 있도록 구성되어 있다.Therefore, the solar lighting system according to the present invention is configured to use a low-cost high-purity acrylic optical fiber cable without using an expensive silica optical fiber having heat resistance as the optical fiber cable 61.

한편, 상기 광섬유케이블(61)에 전달된 가시광선은 산광부(70)를 통해 확산조사되어 직접 태양광이 비추지 못하는 지하층이나 건물내부에 태양광을 공급하게 되는데, 태양조명 시스템의 외곽은 고순도의 아크릴 수지로 구성된 아크릴 돔(50)이 감싸고 있으며, 상기 아크릴 돔(50)은 바람, 먼지, 비 또는 눈 등의 외부 이물질로부터 태양광 집광렌즈와 다른 내부장치들을 보호한다.On the other hand, the visible light transmitted to the optical fiber cable 61 is diffusely irradiated through the diffuser 70 to supply sunlight to the basement or the building that the sunlight does not shine directly, the outside of the solar lighting system is high purity The acrylic dome 50 is formed of an acrylic resin, and the acrylic dome 50 protects the solar condenser lens and other internal devices from external debris such as wind, dust, rain or snow.
