Description

엘씨디 백라이트용 램프 어셈블리{Lamp assembly for LCD backlight in a using}Lamp assembly for LCD backlight in a using}

본 발명은 LCD 백라이트용 램프 어셈블리에 관한 것으로, 더욱 상세하게는 램프 어셈블리의 핫 전극과 콜드 전극을 상호 연결시키는 솔더링 부위가 램프 커버와 접촉되어 단락되는 것을 방지한 엘씨디 백라이트용 램프 어셈블리에 관한 것이다.The present invention relates to a lamp assembly for an LCD backlight, and more particularly, to an LCD backlight lamp assembly that prevents a soldering portion interconnecting the hot and cold electrodes of the lamp assembly from contacting the lamp cover and short-circuiting.

일반적으로 LCD 는 액체와 고체의 중간상태의 물질인 액정이 전극으로 형성된 두 장의 유리기판 사이에 주입되어 전계를 가하여 숫자나 영상을 표시하는 기기로서 LCD 패널의 배면 또는 측면에는 LCD 패널로 빛을 조사하는 램프 어셈블리가 장착된다.In general, an LCD is a device in which a liquid crystal, which is an intermediate state between a liquid and a solid, is injected between two glass substrates formed by electrodes to display numbers or images by applying an electric field. The lamp assembly is mounted.

램프 어셈블리와, 도광판, 확산판 외 다수 시트류는 상호 조합되어 백라이트 어셈블리를 형성하는 바, 백라이트 어셈블리는 직하방식과 에지(edge) 방식으로 구분된다.The lamp assembly, the light guide plate, the diffusion plate, and other sheets are combined with each other to form a backlight assembly, and the backlight assembly is divided into a direct method and an edge method.

직하 방식은 LCD 패널의 밑면에 광원을 두어, 패널 전면을 직접 조광하는 방식으로 광원은 주로 일렉트로 루미네션스가 사용되며, 에지방식은 LCD 패널의 일측면 또는 양측면에 광원을 두어 도광판, 반사판에 광선을 반사, 확산하는 방식으로, 광원으로는 냉극음관이나 열음극관 또는 형광등 등이 사용된다.The direct method is to place the light source on the bottom of the LCD panel, and directly illuminate the front of the panel. The light source is mainly used by electroluminescence, and the edge method uses the light source on one side or both sides of the LCD panel to apply light to the light guide plate and reflector. As a reflection and diffusion method, a cold cathode tube, a hot cathode tube, a fluorescent lamp, or the like is used as the light source.

첨부된 도 1에는 앞서 언급한 램프 어셈블리가 도시되고 있다.The attached lamp assembly is shown in FIG. 1.

램프 어셈블리는 일정 휘도를 발생시키고 양단에 램프 전극(30)이 형성되어 있는 램프(20)와, 램프(20)를 반원형으로 감싸고 있으며 내부에 반사물질이 도포되어 램프(20)로부터 도달한 빛을 반사시키는 램프 커버(10)와, 램프 전극(30)과 결합되어 램프(20)를 점등시키는 전원을 공급하는 전극 와이어와, 전극 와이어(50)와 결합되는 커넥터(미도시)로 구성되어 있다. 여기서 전극 와이어는 핫 와이어(미도시)와 콜드 와이어(50)로 구성되어 있다.The lamp assembly generates a predetermined brightness and surrounds the lamp 20 having the lamp electrodes 30 formed at both ends, and the lamp 20 in a semicircular shape, and a reflective material is coated therein to receive the light reaching from the lamp 20. It is composed of a lamp cover 10 for reflecting, an electrode wire coupled with the lamp electrode 30 to supply power for lighting the lamp 20, and a connector (not shown) coupled with the electrode wire 50. Here, the electrode wire is composed of a hot wire (not shown) and a cold wire 50.

여기서, 램프 전극(30)과 콜드 와이어(50)가 결합될 때 결합 공간을 최대한 절감하기 위하여 램프 전극(30)은 램프 커버(10)의 상부로 올라가서 램프 커버(10)와 평행하도록 절곡되어 있고, 램프 전극(30)의 단부는 콜드 와이어(50)의 단부와 솔더링된다.Here, the lamp electrode 30 is bent to the upper portion of the lamp cover 10 to be parallel to the lamp cover 10 in order to reduce the coupling space when the lamp electrode 30 and the cold wire 50 is coupled to the maximum. The end of the lamp electrode 30 is soldered with the end of the cold wire 50.

이와 같이 콜드 와이어(50)의 단부와 솔더링된 램프 전극(30)이 도전성 램프 커버(10)에 접촉될 경우 단락이 발생하게 되므로 이와 같은 단락을 방지하기 위하여 램프 전극(30)에는 절연성 튜브(40)가 끼워져 있다.As described above, when the end of the cold wire 50 and the soldered lamp electrode 30 come into contact with the conductive lamp cover 10, a short circuit occurs, so that the lamp electrode 30 has an insulating tube 40 to prevent such a short circuit. ) Is inserted.

그러나, 종래 LCD 백라이트용 램프 어셈블리의 램프 전극과 램프 커버는 종종 단락되는 문제점이 있다. 문제점의 원인으로는 램프 전극과 콜드 와이어가 상호 솔더링하는 부분이 단락되는 도전성 램프 커버의 상부에 위치하기 때문에 조립과정에서 절연성 튜브가 벗겨지거나 장시간 사용에 의한 절연성 튜브의 수축에 의하여 램프 커버와 램프 전극이 상호 접촉하여 단락이 발생된다.However, there is a problem that the lamp electrode and the lamp cover of the conventional LCD backlight lamp assembly are often short-circuited. The cause of the problem is that the lamp cover and the lamp electrode are located on the upper part of the conductive lamp cover where the soldering part of the lamp electrode and the cold wire are short-circuited. This mutual contact causes a short circuit.

따라서, 본 발명은 이와 같은 종래의 문제점을 감안하여 안출된 것으로써 본 발명의 목적은 램프 어셈블리의 조립과정이나 장시간 사용하였을 경우라도 램프 어셈블리에 단락이 발생하지 않도록 함에 있다.Accordingly, the present invention has been made in view of such a conventional problem, and an object of the present invention is to prevent a short circuit in the lamp assembly even when the lamp assembly is assembled or used for a long time.

이와 같은 본 발명의 목적을 달성하기 위한 본 발명 LCD 백라이트용 램프 어셈블리는 램프 전극이 형성되어 있는 램프와, 램프를 감싸고 있는 도전성 램프 커버와, 램프가 점등되도록 램프의 램프 전극과 결합되어 있는 전극 와이어를 포함하며, 전극 와이어와 램프 전극은 램프 커버와 접촉되지 않는 영역에서 접합되어 램프 커버와 단락되지 않도록 한 것을 특징으로 한다.In order to achieve the object of the present invention, the LCD backlight lamp assembly of the present invention includes a lamp in which a lamp electrode is formed, a conductive lamp cover surrounding the lamp, and an electrode wire coupled to the lamp electrode of the lamp so that the lamp is turned on. The electrode wire and the lamp electrode are bonded in an area not in contact with the lamp cover, so that the lamp cover is not short-circuited.

이하, 본 발명 LCD 백라이트용 램프 어셈블리를 첨부된 도 2를 참조하여 설명하면 다음과 같다.Hereinafter, the present invention will be described with reference to FIG. 2 to which the lamp assembly for an LCD backlight is attached.

본 발명에 의한 LCD 백라이트용 램프 어샘블리는 전체적으로 보아 램프(120)와 램프(120)를 감싸고 단면이 반원 형상인 램프 커버(110)와, 램프(120)를 점등시키기 위한 전극와이어로 구성되어 있다. 여기서, 전극 와이어는 핫 와이어(미도시) 및 콜드 와이어(150)를 포함하고 있다.The lamp assembly for LCD backlight according to the present invention is composed of a lamp cover 110 having a semicircular cross-section covering the lamp 120 and the lamp 120 as a whole, and an electrode wire for turning on the lamp 120. . Here, the electrode wire includes a hot wire (not shown) and a cold wire 150.

이들 구성요소를 보다 상세하게 설명하면 다음과 같다.These components will be described in more detail as follows.

램프(120)는 일정 직경과 장축을 갖는 형광등 형상으로 램프(120)의 양단에는 앞서 언급한 핫 와이어(미도시) 및 콜드 와이어(150)와 결합하기 위한 램프 전극(130)이 형성되어 있다.The lamp 120 has a shape of a fluorescent lamp having a predetermined diameter and a long axis, and lamp electrodes 130 are formed at both ends of the lamp 120 to be coupled to the aforementioned hot wire (not shown) and the cold wire 150.

중요한 것은 램프 전극(130)중 콜드 와이어(150)와 결합하기 위한 램프 전극(130)은 램프(120)로부터 일정 길이 돌출된 부분에서 한번 절곡되어 램프(120)와 수직을 이루도록 형성되어 있다. 램프(120)의 타측 단부에는 핫 와이어(미도시)와 결합되기 위한 램프 전극(미도시)이 결합되어 있다.Importantly, the lamp electrode 130 for coupling with the cold wire 150 of the lamp electrode 130 is bent once at a portion protruding from the lamp 120 at a predetermined length so as to be perpendicular to the lamp 120. The other end of the lamp 120 is coupled to a lamp electrode (not shown) for coupling with a hot wire (not shown).

이와 같이 구성된 램프 전극에는 핫 와이어(미도시)와 콜드 와이어(150)가 결합되어 있다. 특히, 콜드 와이어(150)의 단부는 램프(120)와 수직으로 뻗어 있는 램프 전극(130)과 도 2에 도시된 바와 같이 솔더링(170)되는 바, 솔더링(170) 위치는 램프 커버(110)로부터 소정 간격 이격된 곳이 바람직하다.The hot wire (not shown) and the cold wire 150 are coupled to the lamp electrode configured as described above. In particular, the end of the cold wire 150 is soldered 170 as shown in Figure 2 and the lamp electrode 130 extending perpendicular to the lamp 120, the soldering 170 position is the lamp cover 110 It is preferable to be spaced apart from the predetermined interval.

한편, 램프 전극(130)은 전원이 인가된 상태로 노출되어 있음으로 인하여 또다른 단락의 위험이 있음으로 램프 전극(130)에는 절연성 튜브(140)가 솔더링(170)된 부분을 덮고 있게 된다.On the other hand, since the lamp electrode 130 is exposed to the power applied state, there is a risk of another short circuit, so that the lamp tube 130 covers the portion where the insulating tube 140 is soldered 170.

이상에서 상세하게 설명한 바와 같이 램프에 형성된 램프 전극과 콜드 와이어를 솔더링에 의하여 결합할 때 솔더링 부분이 램프 커버를 벗어난 부분에 형성되도록 하여 상기 솔더링된 부분과 램프 커버가 단락되어 램프의 휘도 저하, 단락에 의한 고열발생, 램프 수명저하를 예방하는 효과가 있다.As described in detail above, when the lamp electrode formed on the lamp and the cold wire are joined by soldering, the soldered portion is formed in a portion outside the lamp cover so that the soldered portion and the lamp cover are short-circuited to reduce the brightness of the lamp and the short-circuit. It is effective to prevent high heat generation and lamp life decrease.
