More particularly, the present invention is applied to notebooks, LCD monitors, LCD TVs, car navigation, and the like, as well as lamp assembly for small size, light weight, and thinness. The present invention relates to a soldering structure of a fluorescent lamp for a backlight of a liquid crystal display device applicable to an advertising panel including a field, an indoor / outdoor display, and the like.
일반적으로, TFT-LCD의 백라이트로 사용하는 냉음극 형광램프의 리드선과 커넥터 와이어를 연결하는 방법으로 납땜방법을 사용한다.In general, the soldering method is used as a method of connecting the lead wire and the connector wire of the cold cathode fluorescent lamp used as the backlight of the TFT-LCD.
이러한 납땜방법을 사용하여 리드선과 커넥터와이어를 연결하는 종래기술에 따른 백라이트용 형광램프의 납땜구조를 도 1를 참조하여 설명하면 다음과 같다.The soldering structure of the fluorescent lamp for backlight according to the prior art for connecting the lead wire and the connector wire using this soldering method will be described with reference to FIG.
도 1은 종래기술에 따른 백라이트용 형광램프의 납땜구조를 설명하기 위한 단면도이다.1 is a cross-sectional view illustrating a soldering structure of a fluorescent lamp for a backlight according to the prior art.
종래기술에 따른 백라이트용 형광램프의 납땜구조는, 도 1에 도시된 바와같이, 형광램프(10)내부에 장착된 니켈전극(13)에 텅스텐(15)이 연결되고, 상기 텅스텐(25)의 일단은 외부의 램프리드선(27)과 연결된 구조로 되어 있다.In the soldering structure of the fluorescent lamp for backlight according to the prior art, as shown in Figure 1, tungsten 15 is connected to the nickel electrode 13 mounted inside the fluorescent lamp 10, the tungsten 25 of One end has a structure connected to the external lamp lead wire (27).
또한, 상기 램프리드선(17)은 외부의 커넥터와이어(19)의 일단(19a)과 접촉한 상태에서 납땜(soldering)에 의해 연결된다.In addition, the lamp lead wire 17 is connected by soldering in contact with one end 19a of the external connector wire 19.
따라서, 상기 종래기술에 의하면, 상기 램프리드선과 커넥터 와이어를 겹친후 납땜을 진행할때 연결부분에 냉땜 현상등으로 인하여 접촉이 불량하여 떨어지므로써 스파크 현상과 함께 탄화, 발연 등의 현상으로 진전이 될 가능성이 있기때문에 고압부분의 납땜시에 커넥터 와이어를 고리모양으로 꼬아서 조립하는 방법이 적용되었다.Therefore, according to the prior art, when the soldering proceeds after overlapping the lamp lead wire and the connector wire, the contact part is poor due to the cold soldering phenomenon, etc., and thus the possibility of progression in the phenomenon of carbonization, smoke, etc. together with the spark phenomenon. Because of this, the method of assembling the connector wire by twisting the connector wire in the high pressure part is applied.
그러나, 이러한 방법은 조건에 따라 치수 불량 등의 현상이 발생하여 휘도의 균일도 및 램프 전극부분에서 어두운 부분이 발생하는 문제점이 대두된다.However, this method has a problem in that a phenomenon such as a dimensional defect occurs depending on the condition, so that uniformity of luminance and dark portions in the lamp electrode portion arise.
또한, 종래기술에 있어서는, 와이어를 일치시키는 부분의 틈새치수 및 납땜시에 필요한 납의 양에 따라 큰 치수 공차가 필요하고, 와이어를 일치시키는데 약 1초 이상의 시간이 필요하다.Further, in the prior art, a large dimensional tolerance is required depending on the gap size of the portion to which the wire is matched and the amount of lead required for soldering, and a time of about 1 second or more is required to match the wire.
그리고, 종래기술에 있어서는, 납땜부분의 치수공차가 1 mm 이상 커짐으로써 램프의 발광영역이 좁아지는 현상을 피할 수 없었다.In the prior art, the phenomenon that the light emitting area of the lamp is narrowed is not avoided because the dimensional tolerance of the soldered portion is increased by 1 mm or more.
더우기, 종래기술에 있어서는, 램프 글라스에 열충격이 가해져 램프내의 가스방출(leakage) 가능성이 있었다.Moreover, in the prior art, thermal shock was applied to the lamp glass, and there was a possibility of gas leakage in the lamp.
이에 본 발명은 상기 종래기술의 제반 문제점을 해결하기 위하여 안출한 것으로서, 백라이트용 형광램프의 리드선과 커넥터 와이어의 연결부분을 개선하여 유효발광길이를 넓히고, 휘도균일도를 높이며, 램프 조립시에 발생하는 불량율을 줄일 수 있는 액정표시장치의 백라이트용 형광램프의 납땜구조를 제공함에 그 목적이 있다.Accordingly, the present invention has been made to solve the above problems of the prior art, by improving the connection portion of the lead wire and connector wire of the fluorescent lamp for backlight to extend the effective light emission length, to increase the luminance uniformity, It is an object of the present invention to provide a soldering structure of a fluorescent lamp for backlight of a liquid crystal display device which can reduce a defective rate.

본 발명의 제1실시예에 따른 액정표시장치의 백라이트용 형광램프의 납땜 개선구조는, 도 2에 도시된 바와같이, 형광램프(20)내부에 장착된 니켈전극(23)에 텅스텐(25)이 연결되고, 상기 텅스텐(25)의 일단은 한쪽이 막힌 원통형의 니켈슬리브(27)와 결합되어 있다. 여기서, 상기 한쪽이 막힌 니켈슬리브(27)의 외면은 원통형 대신에 경우에 따라서는 여러 형태로 형성할 수도 있다.As shown in FIG. 2, the improved soldering structure of the fluorescent lamp for backlight of the liquid crystal display according to the first embodiment of the present invention is tungsten 25 in the nickel electrode 23 mounted inside the fluorescent lamp 20. This connection is made, and one end of the tungsten 25 is coupled to a cylindrical nickel sleeve 27, one of which is blocked. Here, the outer surface of the nickel sleeve 27 blocked one side may be formed in various forms in some cases instead of a cylindrical shape.
상기 구성으로된 형광램프(20)의 외벽에 연결되어 있는 상기 니켈슬리브(27)의 내부에 외부의 커넥터와이어(29)의 일단(29a)이 삽입된 상태에서 상기 니켈슬리브(27)와 커넥터와이어(29)는 솔더링(soldering)된다.The nickel sleeve 27 and the connector wire while the one end 29a of the external connector wire 29 is inserted into the nickel sleeve 27 connected to the outer wall of the fluorescent lamp 20 having the above configuration. 29 is soldered.
한편, 본 발명의 제2실시예로서, 형광램프(30)의 외벽에 측면이 결합되어 있는 니켈슬리브(37)내부에 커넥터와이어(39)의 일단(39a)을 삽입한후 니켈슬리브 (37)와 커넥터와이어(39)의 일단(39a)의 접촉부분을 솔더링하므로써 상기 형광램프 (30)와 커넥터와이어(39)가 직각방향을 이루게 된다. 즉, 커넥터와이어(39)가 삽입되는 니켈슬리브(37)의 방향을 변경하므로써 다양한 형태로 커넥터와이어(39)와 연결시킬 수가 있다.On the other hand, as a second embodiment of the present invention, the nickel sleeve 37 after inserting one end 39a of the connector wire 39 into the nickel sleeve 37 having side surfaces coupled to the outer wall of the fluorescent lamp 30. The fluorescent lamp 30 and the connector wire 39 are perpendicular to each other by soldering the contact portion of the one end 39a of the connector wire 39. That is, by changing the direction of the nickel sleeve 37 into which the connector wire 39 is inserted, the connector wire 39 can be connected to the connector wire 39 in various forms.
그리고, 본 발명의 제3실시예로서, 형광램프(40)의 외벽에 결합되어 있는 램프리드선(47)의 외면에 일단(49a)이 고리형태로 된 커넥터와이어(49)를 끼운후 솔더링에 의해 연결할 수도 있다.Then, as a third embodiment of the present invention, by inserting the connector wire 49 of one end 49a in a ring shape on the outer surface of the lamp lead wire 47 coupled to the outer wall of the fluorescent lamp 40 by soldering You can also connect.
상기에서 설명한 바와같이, 본 발명에 따른 액정표시장치의 백라이트용 형광램프의 납땜 개선방법에 있어서는 다음과 같은 효과가 있다.As described above, the soldering improvement method of the fluorescent lamp for backlight of the liquid crystal display device according to the present invention has the following effects.
종래의 경우 와이어를 일치시키는 부분의 틈새치수 및 납땜시 필요한 납의 양에 따라 큰 치수공차가 필요했으나, 본 발명에 있어서의 납땜방법을 사용하는 경우에 납땜시 발생하는 길이공차를 약 0.5 μm 이하로 줄일 수가 있어 백라이트 조립시 효율을 높일 수가 있다In the conventional case, a large dimensional tolerance was required depending on the gap size of the portion where wires were matched and the amount of lead required for soldering. However, when the soldering method of the present invention is used, the length tolerance generated during soldering is about 0.5 μm or less. It can reduce the efficiency of backlight assembly
또한, 종래의 경우 와이어를 일치시키는데 약 1초 이상의 시간이 필요했으나, 본 발명에서의 납땜방법을 사용하는 경우 와이어를 삽입부분에만 넣어 납땜하면 되므로 납땜시간 및 불량 발생을 최대한 줄일 수가 있다.In addition, in the conventional case, a time of about 1 second or more was required to match the wires. However, in the case of using the soldering method of the present invention, only the wire is inserted into the insertion part and soldered, thereby reducing the soldering time and the occurrence of defects as much as possible.
그리고, 종래의 경우 납땜부분의 치수가 커짐으로 램프의 발광영역이 좁아지는 현상을 필할 수 없었으나, 본 발명에서의 납땜방법을 사용하는 경우 치수가 1 mm 이상의 치수가 줄어 들어 램프의 발광영역을 넓히고, 발광영역이 넓어짐으로써 휘도균일도를 높일 수가 있다.In the related art, the size of the soldered portion is increased so that the light emitting area of the lamp may not be narrowed. However, when the soldering method of the present invention is used, the size of the lamp is reduced by 1 mm or more, thereby reducing the light emitting area of the lamp. The luminance uniformity can be increased by widening the light emitting area.
더우기, 종래의 경우 램프 글라스에 열충격이 가해져 램프내의 가스방출이 발생할 가능성이 있었으나, 본 발명에서의 납땜구조를 사용할 경우 램프에는 최소한의 열전달만이 가능하여 램프내의 가스방출 현상이 없어진다.Furthermore, in the related art, thermal shock is applied to the lamp glass, so that gas emission in the lamp may occur. However, when the soldering structure of the present invention is used, only a minimum heat transfer is possible in the lamp, so that the gas discharge phenomenon in the lamp is eliminated.
한편, 본 발명은 상술한 특정의 바람직한 실시예에 한정되지 아니하며, 청구범위에서 청구하는 본 발명의 요지를 벗어남이 없이 당해 발명이 속하는 분야에서 통상의 지식을 가진 자라면 누구든지 다양한 변경 실시가 가능할 것이다.On the other hand, the present invention is not limited to the above-described specific preferred embodiments, and various changes can be made by those skilled in the art without departing from the gist of the invention claimed in the claims. will be.
