Description

엘이디 형광램프를 이용한 광촉매 살균램프{photocatalyst sterilization lamp that use LED phosphor lamp}Photocatalyst sterilization lamp that use LED phosphor lamp

본 발명은 엘이디 형광램프의 표면을 광촉매 유리섬유필터로 감싸 구성함에 따라, 조명으로서의 기능뿐만 아니라, 실내외 공기의 살균 및 소독이 동시에 이루어지고, 특히 유해가스 제거 및 탈취의 효과를 기대할 수 있는 엘이디 형광램프를 이용한 광촉매 살균램프에 관한 것이다.The present invention is configured by wrapping the surface of the LED fluorescent lamp with a photocatalyst glass fiber filter, not only functions as lighting, but also sterilization and disinfection of indoor and outdoor air at the same time, in particular LED fluorescent lamps that can be expected to remove harmful gases and deodorization It relates to a photocatalyst sterilizing lamp using a lamp.

일반적으로 엘이디(LED)는 반도체의 p-n 접합구조를 이용하여 주입된 소수 캐리어(전자)를 만들어내고, 이들의 재결합에 의하여 발광시키는 것인데 이러한 엘이디로부터 발산되는 빛은 직진성이 강하여 일반 조명으로 사용하기에는 적합하지 않았다. 그러나, 근래에는 엘이디가 갖는 장점이 있기 때문에 그 단점(빛의 직진성)을 극복하여 일반 조명으로 사용하기 위한 램프가 소개되었다.In general, LEDs generate a minority carrier (electrons) injected by using a pn junction structure of a semiconductor, and emit light by recombination of them. Light emitted from these LEDs is strong and suitable for general lighting. Did not do it. However, in recent years, because of the advantages of the LED has been introduced to overcome the disadvantages (the straightness of the light) for use as a general lighting lamp.

대표적으로 엘이디와, 이 엘이디를 고정하기 위한 베이스 프레임과, 그 위에서 빛의 난반사를 유도하는 불투명 아크릴소재의 커버를 조립하여 하나의 모듈로 구성하고, 이 모듈을 여러 개 배열하여 하나의 램프를 만드는 것이었다. 그러나 이러한 종류의 엘이디 램프는 기존의 일반 램프들과 그 모양 및 치수가 확연히 달라 서 항상 새로운 금형으로 새롭게 제작해야 할 뿐만 아니라 제조가 어렵고, 수명이 짧으며 가격이 높아지는 단점이 있다. 특히 빛이 투과량 감소가 심하고 부드럽지 못하기 때문에 널리 사용되지 못하였다. 이러한 문제점을 해결하기 위해 엘이디 광원으로부터 나오는 빛을 램프 초자관 내부의 형광물질에 의해 난반사가 이루어지고 나서 발산되도록 함으로써 빛의 투과량을 높이고, 더 부드러운 빛으로 발산될 수 있도록 하는 엘이디 형광램프가 제공된 바 있다.Representatively, the LED, the base frame for fixing the LED, and the cover of opaque acrylic material that induces diffuse reflection of light thereon are assembled into one module, and the modules are arranged to make one lamp. Was. However, this type of LED lamp is different from the conventional lamps, the shape and dimensions are so different that it is not only to manufacture a new mold always, but also difficult to manufacture, short life and high price. In particular, the light has not been widely used because the decrease in the amount of transmission is severe and soft. In order to solve this problem, LED fluorescent lamps are provided to increase light transmission and to emit softer light by causing light emitted from the LED light source to be diffused after being diffused by the fluorescent material inside the lamp tube. have.

또한, 광촉매란 광(光)을 받으면 촉매 반응을 일으키는 물질이다. 광촉매 중 이산화티타늄이 가장 많이 사용되고 있다. 이는 이산화티타늄이 내산성, 내알카리성 등이 좋으며 인체에 무해하기 때문이다. 각종 오염물질을 무해한 물질로 변화시켜 주는 친환경적 소재이다.In addition, a photocatalyst is a substance which causes a catalytic reaction when it receives light. Titanium dioxide is the most used photocatalyst. This is because titanium dioxide has good acid resistance and alkali resistance and is harmless to the human body. It is an environmentally friendly material that transforms various pollutants into harmless materials.

이산화티타늄 광촉매는 n형 반도체로서 자외선(400mm)을 받으면 전자(Electron) 전공대(Electron Hole)가 형성되어 강한 산화력을 가진 하이드록시 라티칼(-OH)과 슈퍼 옥사이드을 생성한다. 이 하드드록시 라디칼과 슈퍼 옥사이드가 유기 화합물을 산화 분해시켜 물과 탄산가스로 변화시킨다.Titanium dioxide photocatalysts are n-type semiconductors, and when subjected to ultraviolet rays (400 mm), electrons (electrons) are formed to produce hydroxy radicals (-OH) and super oxides with strong oxidizing power. These hard hydroxy radicals and super oxides oxidize and decompose organic compounds into water and carbon dioxide.

이런 원리로 공기 중의 오염물질을 산화, 분해시켜 무해한 물과 탄산가스로 변화시키고 수중의 오염 물질인 유기화합물을 분해시켜 물과 탄산가스로 변화시키게 된다. 또한 세균도 유기 화합물이므로 광촉매의 강한 산화작용에 의해 산화분해되어 살균된다.In this way, air pollutants are oxidized and decomposed into harmless water and carbon dioxide, and organic compounds, which are pollutants in water, are decomposed into water and carbon dioxide. Since bacteria are also organic compounds, they are oxidatively decomposed and sterilized by the strong oxidation of the photocatalyst.

따라서, 현재 이슈화 되고있는 엘이디 형광램프는 단순히 빛을 발산하는 조명으로서의 기능뿐만 아니라, 광촉매와 접목하여 전시장 및 일반 가정 등의 실내외 공기의 살균 및 소독이 동시에 이루어지도록 하고, 특히 공장 및 각종 산업 현장에서 필요한 유해가스 제거 및 탈취 능력을 구비한 엘이디 형광램프의 제공이 시급히 이루어져야 할 것이다.Therefore, LED fluorescent lamps, which are currently being issued, not only function as light emitting light but also combine with photocatalyst to simultaneously disinfect and disinfect indoor and outdoor air in exhibition halls and general homes, and especially in factories and various industrial sites. There should be an urgent need to provide LED fluorescent lamps with the ability to remove and deodorize harmful gases.

먼저, 본 발명에 따른 엘이디 형광램프를 이용한 광촉매 살균램프(10)는 30-60㎚크기의 이산화티탄(TiO2)을 다공성 무기산화물로 코팅처리하여 광촉매액을 구비 하고; 상기 광촉매액을 무기바인더와 혼합하여 광촉매코팅액을 구비하며; 유리섬유를 격자형으로 직조하여 구성된 유리섬유망체를 30 ~ 50℃의 온도로 가열하여 열처리하고; 상기 광촉매코팅액을 15 ~ 40℃의 온도로 가열한 뒤, 열처리된 유리섬유망체를 가열된 광촉매코팅액에 30 ~ 60분 동안 침지하며; 상기 침지된 유리섬유망체를 탈수처리한 뒤 200 ~ 300℃의 온도에서 5 ~ 30분간 열풍건조하여 광촉매 유리섬유필터(100)를 형성하고; 상기 광촉매 유리섬유필터(100)를 엘이디(LED) 형광램프(200)의 외측표면을 감싸도록 커버하여 구성된 것을 기술상의 요점으로 한다.First, the photocatalyst sterilizing lamp 10 using the LED fluorescent lamp according to the present invention comprises a photocatalyst liquid by coating a titanium dioxide (TiO 2 ) having a size of 30-60 nm with a porous inorganic oxide; Mixing the photocatalyst liquid with an inorganic binder to provide a photocatalyst coating liquid; Heat-treating the glass fiber network constructed by weaving the glass fiber in a lattice shape to a temperature of 30 to 50 ° C .; After heating the photocatalyst coating solution to a temperature of 15 ~ 40 ℃, the heat-treated glass fiber network is immersed in the heated photocatalyst coating solution for 30 to 60 minutes; Dehydrating the immersed glass fiber network and hot-air-dried at a temperature of 200 to 300 ° C. for 5 to 30 minutes to form a photocatalyst glass fiber filter 100; The photocatalyst glass fiber filter 100 is configured to cover the outer surface of the LED (LED) fluorescent lamp 200 to the technical point.

상기 광촉매 유리섬유필터(100)는 30-60㎚크기의 이산화티탄(TiO2)을 다공성 무기산화물로 코팅처리하여 광촉매액을 구비하고, 상기 광촉매액을 무기바인더와 혼합하여 광촉매코팅액을 구비한 뒤, 유리섬유를 격자형으로 직조하여 구성된 유리섬유망체를 30 ~ 50℃의 온도로 가열하여 열처리하고, 상기 광촉매코팅액을 15 ~ 40℃의 온도로 가열한 뒤, 열처리된 유리섬유망체를 가열된 광촉매코팅액에 30 ~ 60분 동안 침지하고, 상기 침지된 유리섬유망체를 탈수처리한 뒤 200 ~ 300℃의 온도에서 5 ~ 30분간 열풍건조하여 구성된다.The photocatalyst glass fiber filter 100 has a photocatalyst liquid by coating a titanium dioxide (TiO 2 ) having a size of 30-60 nm with a porous inorganic oxide, and a photocatalyst coating liquid by mixing the photocatalyst liquid with an inorganic binder. After heating the glass fiber mesh formed by weaving the glass fibers in a lattice shape to a temperature of 30 ~ 50 ℃, and heating the photocatalyst coating solution to a temperature of 15 ~ 40 ℃, the heat-treated glass fiber network photocatalyst It is immersed in the coating solution for 30 to 60 minutes, dehydrated glass fiber network and then dried by hot air for 5 to 30 minutes at a temperature of 200 ~ 300 ℃.

이산화티탄(TiO2)의 크기가 30-60㎚로 형성될 경우, 미립화된 이산화티탄(TiO2)의 구조에 따라 전체적인 이산화티탄(TiO2)의 표면적이 증가하여 광촉매의 살균효율을 증가시킬 수 있으며, 다공성 무기산화물에 의해 마련된 기공 사이로 이산화티탄(TiO2)이 침투하여 고정될 수 있는 것이다. When the size of titanium dioxide (TiO 2 ) is formed to 30-60 nm, the surface area of the titanium dioxide (TiO 2 ) may increase according to the structure of the atomized titanium dioxide (TiO 2 ) to increase the sterilization efficiency of the photocatalyst. In addition, titanium dioxide (TiO 2 ) may penetrate and be fixed between pores provided by a porous inorganic oxide.

또한, 유리섬유는 용융한 유리를 섬유 모양으로 한 광물섬유를 의미하는 것 으로, 고온에 견디며, 불에 타지 않고, 화학적 내구성이 있기 때문에 부식하지 않는 성질을 구비하므로 엘이디 형광램프를 감싸더라고 변형이 발생하지 않기 때문에 상기와 같은 유리섬유를 망체로 직조하여 유리섬유망체를 형성하는 것이다.In addition, glass fiber refers to a mineral fiber made of molten glass as a fiber shape, and because it is resistant to high temperature, does not burn, and does not corrode because it is chemically durable, the glass fiber is deformed even when it is wrapped around the LED fluorescent lamp.

또한, 광촉매코팅액에서 코팅이 완료된 유리섬유망체는 건조가 신속히 이루어지도록 탈수처리하게 되는데, 원심분리기를 이용한 회전식 탈수방식을 비롯하여 롤러사이를 통과하는 가압방식 등 공지된 다양한 방법으로 탈수처리할 수 있다.In addition, the glass fiber mesh is coated in the photocatalyst coating solution is subjected to a dehydration treatment so that the drying is carried out quickly, it can be dewatered by a variety of known methods such as a rotary dehydration method using a centrifuge, a pressure method passing between the rollers.

상기 탈수처리된 유리섬유망체는 표면에 광촉매코팅액이 흐르지않을 정도로 코팅되어져 있고, 수분을 증발하여 광촉매코팅액의 성분을 유리섬유망체에 고정하도록 200 ~300℃의 온도의 열풍을 5 ~ 30분간 처리하여 건조가 이루어지도록 하며, 건조가 완료되면 광촉매 유리섬유필터(100)가 완료되는 것이다.The dehydrated glass fiber mesh is coated so that the photocatalytic coating liquid does not flow on the surface, and the hot air at a temperature of 200 to 300 ° C. is treated for 5 to 30 minutes to evaporate moisture to fix the component of the photocatalyst coating liquid to the glass fiber mesh. Drying is made, and when the drying is completed, the photocatalyst glass fiber filter 100 is completed.

상기와 같이 구비된 광촉매 유리섬유필터(100)는 엘이디(LED) 형광램프(200)의 외측표면을 감싸도록 커버되어 본 발명 엘이디 형광램프를 이용한 광촉매 살균램프(10)가 완성되는 것이다.The photocatalyst glass fiber filter 100 provided as described above is covered to surround the outer surface of the LED fluorescent lamp 200 to complete the photocatalyst sterilization lamp 10 using the LED fluorescent lamp of the present invention.
