Description
본 발명은 외부전극 형광램프에 관한 것으로서, 더욱 상세하게는 형광램프의 양단부에 리드와이어를 결합하고 그 리드와이어를 통하여 전원을 공급받을 수 있도록 형광램프의 양단부 외측 둘레면에 전극을 형성하여 형광램프를 간편하게 고정시킴과 함께 복수개의 형광램프가 설치되는 멀티램프를 균일하게 점등시킬 수 있는 외부전극 형광램프에 관한 것이다.The present invention relates to an external electrode fluorescent lamp, and more particularly to a fluorescent lamp by coupling the lead wires to both ends of the fluorescent lamp and forming electrodes on the outer peripheral surface of both ends of the fluorescent lamp so that power can be supplied through the lead wires. The present invention relates to an external electrode fluorescent lamp that can lightly fix and uniformly light a multi-lamp in which a plurality of fluorescent lamps are installed.
액정표시장치(이하 'LCD'라 함)는 저전력을 이용하여 구동이 가능하고 선명한 색 재현 능력을 가지는 장점이 있는 반면에, 문자 또는 도형 등이 표시되는 LCD 패널 자체가 직접 빛을 내지 못하는 비발광성 소자이다. 따라서 표시장치로서의 역할을 하도록 LCD 패널의 후위 또는 저부에서 빛을 LCD 패널로 조사(照射)하는 백라이드장치(backlight unit)가 요구된다. Liquid crystal displays (hereinafter referred to as "LCDs") have the advantage of being able to be driven using low power and having vivid color reproduction, while the LCD panel itself, which displays characters or figures, does not emit light directly. Element. Therefore, there is a need for a backlight unit for irradiating light to the LCD panel at the rear or bottom of the LCD panel to serve as a display device.
상기 백라이트장치에는 형광램프가 사용되고 그 형광램프는 유리관내에 수은과 불활성 가스가 충입되고, 상기 유리관 내벽에는 형광체가 도포되어 있으며 유리관의 양측에는 전극이 설치되어 있는 것으로서, 상기 전극에 전계를 가하면 전자가 생성되고, 더욱 높은 전계를 가할수록 전자는 유리관내에서 가속하게 되며, 가속된 전자가 유리관내의 수은원자를 이온화시키고 이온화된 수은 원자는 약 254nm의 자외선을 방출하게 되므로 빛이 발생되는 것이다.Fluorescent lamps are used in the backlight device, and the fluorescent lamps are filled with mercury and an inert gas in the glass tube, phosphors are coated on the inner wall of the glass tube, and electrodes are provided on both sides of the glass tube. Is generated and electrons accelerate in the glass tube as the higher electric field is applied, and light is generated because the accelerated electrons ionize the mercury atoms in the glass tube and the ionized mercury atoms emit ultraviolet rays of about 254 nm.
상기 백라이트장치는 빛을 제공하는 형광램프의 설치 위치에 따라서 크게 2종류로 구분된다. 첫 째는 LCD의 측면에서 빛을 제공하는 에지방식(또는 측면형) 백라이트로서, 이는 소형 LCD장치(휴대폰, PDA 등)에 사용되고 있다. 둘 째는 LCD의 저면에서 빛을 직접 제공하는 직하방식 백라이트로서, 이는 에지방식 백라이트에 비하여 휘도가 높고 중대형 LCD장치(노트북, TV 등)에 사용되고 있다.The backlight device is classified into two types according to the installation position of the fluorescent lamp for providing light. The first is an edge type (or side) backlight that provides light at the side of the LCD, which is used in small LCD devices (such as mobile phones and PDAs). Second, the direct backlight provides light directly from the bottom of the LCD, which is higher in brightness than the edge backlight and is used in medium and large LCD devices (laptops, TVs, etc.).
이러한 백라이트 장치에 설치되는 형광램프는 전극의 위치에 따라서 크게 2종류로 구분된다. 첫 째는 형광램프의 내부에 전극이 내장되어 있는 내부전극 형광램프(CCFL : Cold Cathode Fluorescent Lamp)이고, 둘 째는 형광램프의 외부에 전극이 설치되어 있는 외부전극 형광램프(EEFL : External Electrode Florescent Lamp)로서, 이들은 구조상의 차이점을 보이고 있으며 이를 첨부도면을 참조하여 상세히 설명하면 다음과 같다.Fluorescent lamps installed in such a backlight device are classified into two types according to the position of the electrode. The first is the Cold Cathode Fluorescent Lamp (CCFL) with the built-in electrode inside the fluorescent lamp. The second is the External Electrode Florescent Lamp (EEFL) with the electrode installed outside the fluorescent lamp. As lamps, they show structural differences, which will be described in detail with reference to the accompanying drawings.
도 1은 종래 내부전극 형광램프를 나타낸 사시도이고, 도 2는 종래 내부전극 형광램프의 단부를 나타낸 단면도이다.1 is a perspective view showing a conventional internal electrode fluorescent lamp, Figure 2 is a cross-sectional view showing the end of the conventional internal electrode fluorescent lamp.
여기에서 참조되는 바와 같이 유리관(1)의 양단부에는 유리관(1)의 내부와 외부를 차단하여 유리관(1)을 밀봉하는 비드(3)가 부착되어 있고, 그 비드(3)의 내부에는 리드와이어(2)가 관통 삽입되어 있으며, 상기 리드와이어(2)의 일단은 유리관(1)의 외부로 돌출되고 타단은 유리관(1)의 내부로 돌출되게 삽입되어 있다. 그리고 상기 유리관(1)의 내부로 돌출된 리드와이어(2)에는 전자 방출을 위한 내부전극(5)이 설치되어 있다.As referred to herein, a bead 3 is attached to both ends of the glass tube 1 to block the inside and the outside of the glass tube 1 to seal the glass tube 1, and the lead wire inside the bead 3. (2) is inserted through, and one end of the lead wire (2) protrudes out of the glass tube (1) and the other end is inserted to protrude into the glass tube (1). In addition, the lead wire 2 protruding into the glass tube 1 is provided with an internal electrode 5 for electron emission.
이러한 내부전극 형광램프는 양측 선단부에 돌출 형성된 리드와이어(2)를 이용하여 형광램프를 고정시킨 후 상기 리드와이어(2)를 통하여 전원(6)을 공급하여 형광램프를 점등시키는 것으로서, 간편하게 고정시킬 수는 있지만 복수개를 설치할 경우에는 형광램프를 점등시킬 때 형광램프 내부의 임피던스 차이로 인하여 복수개의 형광램프 중 어느 하나가 점등되면 전압강하가 크게 발생하게 되어 복수개의 형광램프를 균일하게 점등시키지 못하게 되므로 멀티 램프를 구동하는 직하방식 백라이트 장치에는 적당하지 못하게 되는 문제점이 있었다.The internal electrode fluorescent lamp is fixed by fixing the fluorescent lamp using the lead wires 2 protruding at both ends, and then supplying a power supply 6 through the lead wires 2 to light the fluorescent lamps. Although it is possible to install a plurality of fluorescent lamps, when one of the fluorescent lamps is turned on due to the impedance difference inside the fluorescent lamp when the fluorescent lamps are turned on, a large voltage drop will occur and thus the plurality of fluorescent lamps cannot be uniformly lit. There is a problem that the direct type backlight device for driving the multi-lamp is not suitable.
따라서 멀티 램프의 균일한 점등을 위하여 직하방식 백라이트 장치에는 외부전극 형광램프가 사용되고 있으며 그 외부전극 형광램프의 구조를 상세히 설명하면 다음과 같다.Therefore, the external electrode fluorescent lamp is used in the direct type backlight device for uniform lighting of the multi lamp, and the structure of the external electrode fluorescent lamp will be described in detail as follows.
도 3은 종래 외부전극 형광램프를 나타낸 사시도이고, 도 4는 종래 외부전극 형광램프의 단부를 나타낸 단면도이다.3 is a perspective view showing a conventional external electrode fluorescent lamp, Figure 4 is a cross-sectional view showing the end of the conventional external electrode fluorescent lamp.
여기에서 참조되는 바와 같이 유리관(1)의 양단부는 밀봉되어 있고 상기 유리관(1)이 외측 둘레면 양단부에는 접착제(7)를 매개로 외부전극(4)이 부착되어 있으며 상기 외부전극(4)에는 전원(6)을 공급하기 위한 배선이 연결되어 있다.As referred to herein, both ends of the glass tube 1 are sealed, and the external electrode 4 is attached to both ends of the outer circumferential surface of the glass tube 1 via the adhesive 7, and the external electrode 4 Wiring for supplying the power supply 6 is connected.
이와 같은 외부전극 형광램프는 별도의 지지수단(도면 미도시)을 이용하여 고정시킨 상태에서 복수개를 동시에 점등시키는 것으로서, 복수개의 형광램프를 동시에 사용하는 멀티램프에서 균일한 점등은 가능하지만 외부전극 형광램프를 고정시키기 위해서는 별도의 지지수단이 반드시 필요하게 되므로 구조가 복잡하고 유리관(1)의 외부에 외부전극(4)을 부착하는 과정 및 그 외부전극(4)에 배선을 연결하는 작업을 반드시 하여야 하는 등의 문제점이 있었다. Such external electrode fluorescent lamps illuminate a plurality of lights simultaneously in a fixed state by using a separate support means (not shown), and uniform lighting is possible in a multilamp using a plurality of fluorescent lamps simultaneously. In order to fix the lamp, since a separate supporting means is necessary, the structure is complicated, and the process of attaching the external electrode 4 to the outside of the glass tube 1 and connecting the wires to the external electrode 4 must be performed. There was a problem such as.
또한 상기 외부전극 형광램프에는 유리관(1)의 외측 둘레면에 접착제(7)를 매개로 외부전극(4)이 부착되므로 유리관(1)과 외부전극(4) 사이에 공기층이 형성되어 고전압이 요구되는 형광램프에서 오존이 발생하고 그 오존으로 인한 냄새가 발생하게되는 문제점이 있었다.In addition, since the external electrode 4 is attached to the external electrode fluorescent lamp via the adhesive 7 on the outer circumferential surface of the glass tube 1, an air layer is formed between the glass tube 1 and the external electrode 4 so that a high voltage is required. There is a problem that ozone is generated in the fluorescent lamp that is and the smell caused by the ozone is generated.
본 발명은 상기한 문제점 해결하기 위하여 발명한 것으로서, 그 목적은 복수개를 동시에 점등시키는 멀티 램프로 사용할 때 균일한 점등이 가능하고 별도의 지지수단을 이용하지 않고도 형광램프를 PCB기판에 간단하게 부착시킬 수 있는 외부전극 형광램프를 제공함에 있다. The present invention has been invented to solve the above problems, the object of which is to uniformly light when used as a multi-lamp to turn on a plurality of at the same time and to easily attach a fluorescent lamp to the PCB substrate without using a separate support means To provide an external electrode fluorescent lamp that can be.
상기 목적을 달성하기 위한 본 발명의 특징적인 구성을 설명하면 다음과 같다.Referring to the characteristic configuration of the present invention for achieving the above object is as follows.
본 발명은 유리관의 내부가 밀봉되도록 유리관의 양단부에 부착되는 비드와, 상기 비드의 중앙에 삽입되고 일측은 외부로 돌출된 리드와이어와, 상기 리드와이어와 전기적으로 연결되도록 유리관의 양단부 외측 둘레면에 코팅된 외부전극이 포함된 것이다.The present invention is a bead attached to both ends of the glass tube so as to seal the inside of the glass tube, the lead wire is inserted into the center of the bead and one side protrudes outward, and the outer peripheral surface of both ends of the glass tube to be electrically connected to the lead wire Coated external electrode is included.
이와 같은 특징을 갖는 본 발명을 상세하게 설명하면 다음과 같다.Referring to the present invention having such characteristics in detail as follows.
도 5는 본 발명에 따른 외부전극 형광램프를 나타낸 단면도이다.5 is a cross-sectional view showing an external electrode fluorescent lamp according to the present invention.
여기에서 참조되는 바와 같이 유리관(1)의 내부를 밀봉시키도록 상기 유리관(1)의 양 단부에는 비드(3)가 부착되어 있고, 그 비드(3)에는 전원(6)을 공급하기 위한 리드와이어(2)가 삽입되어 있되, 상기 리드와이어(2)의 일단은 외부로 돌출되어 있다.As referred to herein, beads 3 are attached to both ends of the glass tube 1 to seal the inside of the glass tube 1, and the lead wires for supplying power 6 to the beads 3. (2) is inserted, but one end of the lead wire (2) protrudes outward.
그리고 상기 유리관(1)의 양측 단부에는 외부전극(4)이 코팅되어 있되, 그 외부전극(4)은 리드와이어(2)에 인가된 전원을 공급받을 수 있도록 상기 리드와이어(2)와 전기적으로 연결되어 있다.In addition, external electrodes 4 are coated at both ends of the glass tube 1, and the external electrodes 4 are electrically connected to the lead wires 2 so as to receive power applied to the lead wires 2. It is connected.
또는 도 6에 나타낸 바와 같이 리드와이어(2)의 외측 둘레면을 감싸도록 외부전극(4)을 코팅하여도 무방하다.Alternatively, as illustrated in FIG. 6, the external electrode 4 may be coated to surround the outer circumferential surface of the lead wire 2.
이와 같이 구성된 본 발명의 사용상태를 나타낸 첨부도면 도 7을 참조하여 상세히 설명하면 다음과 같다.Referring to the accompanying drawings showing the use of the present invention configured as described above in detail with reference to FIG.
여기에서 참조되는 바와 같이 형광램프를 설치하기 위한 간격에 따라서 PCB기판(8)의 상면에 솔더링패드(9)를 형성하고 그 솔더링패드(9)에 형광램프의 리드와이어(2)를 솔더링하면 형광램프의 고정이 되는 것으로서, 이는 별도의 지지수단을 사용하지 않고도 외부전극 형광램프를 간단하게 고정시킬 수 있게되는 것이다. 그리고 복수개의 외부전극 형광램프를 이용하여 멀티램프를 형성하게 되므로 균일한 점등이 가능하게 되는 것이다.As described herein, the soldering pad 9 is formed on the upper surface of the PCB substrate 8 according to the interval for installing the fluorescent lamp, and the lead wire 2 of the fluorescent lamp is soldered to the soldering pad 9 for fluorescence. As the lamp is fixed, it is possible to simply fix the external electrode fluorescent lamp without using a separate support means. In addition, since a plurality of external electrode fluorescent lamps are used to form a multilamp, uniform lighting is possible.
