LCD 후광장치용 램프 어셈블리 구조Lamp assembly structure for LCD backlight device

본 발명은 액정표시소자(liquid crystal display:이하, LCD라 한다) 후광장치용 램프 어셈블리(lamp assembly) 구조에 관한 것으로, 좀더 상세하게는 램프 카바 및 도광판 어셈블리간의 마찰면을 최소화함으로써, 램프 어셈블리의 조립성을 향상시킬 수 있도록 하는 LCD 후광장치용 램프 어셈블리 구조에 관한 것이다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a lamp assembly structure for a liquid crystal display (hereinafter referred to as LCD) backlight device, and more particularly, by minimizing the friction surface between the lamp cover and the light guide plate assembly. It relates to a lamp assembly structure for an LCD backlight device that can improve the assembly.

최근 현대사회가 정보사회화되어감에 따라 정보표시장치의 하나인 LCD 장치의 중요성은 점차 증대되는 추세에 있다.Recently, as the modern society becomes information socialized, the importance of the LCD device, which is one of the information display devices, is gradually increasing.

이러한 LCD 장치에서 특히, LCD 후광장치용 램프 어셈블리의 역할과 기능은 갈수록 중요한 과제로 대두되고 있는 바, 이는 램프 어셈블리의 구조에 따라서 LCD모듈(module)의 크기 및 광랑 등이 달라져, LCD 모듈의 기계적.광학적 특성이 많은 영향을 받기 때문이다.In such an LCD device, in particular, the role and function of the lamp assembly for the LCD backlight device has become an important task. The size and gloss of the LCD module are changed according to the structure of the lamp assembly. Because optical properties are much affected.

도 1은 이러한 기능을 수행하는 종래의 LCD 후광장치의 구조를 개략적으로 도시한 사시도이다.1 is a perspective view schematically showing the structure of a conventional LCD backlight device that performs this function.

도시된 바와 같이, 종래의 LCD 후광장치는 램프 홀더(3)에 의해 고정된 램프(4)와, 램프 홀더(3) 위에 탑재되어 램프를 보호하는 램프 카바(2)로 구성된 램프 어셈블리를 포함한다.As shown, a conventional LCD backlight device comprises a lamp assembly composed of a lamp 4 fixed by a lamp holder 3 and a lamp cover 2 mounted on the lamp holder 3 to protect the lamp. .

이때, 참조번호 1b는 도광판을, 참조번호 1a는 도광판에 적층된 시트(Sheet)를, 참조번호 5는 램프 어셈블리에 연결된 와이어를 나타낸다.In this case, reference numeral 1b denotes a light guide plate, reference numeral 1a denotes a sheet stacked on the light guide plate, and reference numeral 5 denotes a wire connected to the lamp assembly.

이러한 LCD 후광장치를 조립할 경우, 작업자는 램프 카바(2)의 양측부(2b,2c)가 도광판 어셈블리(1)의 입광부쪽 상· 하부면을 지지하도록 한 후, 손잡이(2a)를 통해 램프 어셈블리를 화살표 방향으로 슬라이딩시킴으로써, 도광판 어셈블리(1)의 일측면에 램프 어셈블리가 장착되도록 한다.When assembling such an LCD backlight device, an operator causes both side portions 2b and 2c of the lamp cover 2 to support the upper and lower surfaces of the light guide portion of the light guide plate assembly 1, and then the lamp through the handle 2a. By sliding the assembly in the direction of the arrow, the lamp assembly is mounted on one side of the light guide plate assembly 1.

이때, 도광판 어셈블리(1)의 상· 하부면은 램프 카바(2)의 양측부(2b,2c)에 끼워져 견고히 고정되고 이에 따라, LCD 후광장치는 소기의 발광기능을 적절히 수행할 수 있다.In this case, the upper and lower surfaces of the light guide plate assembly 1 are fitted to both side portions 2b and 2c of the lamp cover 2 and are firmly fixed. Accordingly, the LCD backlight device can properly perform a desired light emitting function.

그러나, 이러한 기능을 수행하는 종래의 LCD 후광장치에는 몇가지 중대한 문제점이 있다.However, there are some serious problems with conventional LCD backlight devices that perform this function.

첫째, 램프(4)의 수명이 끝나거나 또는 기타 다른 요인들로 인해 램프 어셈블리를 교체해 주어야 할 경우, 상술한 바와 같이, 램프 어셈블리를 슬라이딩 방식으로 도광판 어셈블리(1)에 조립하는 바, 이때, 램브 카바(2)와 도광판 어셈블리(1)간의 슬라이딩 마찰에 따른 반발력으로 인해 용이한 교체작업을 수행할 수 없는 문제점이 있다.First, when the lamp assembly needs to be replaced due to the end of the life of the lamp 4 or other factors, the lamp assembly is assembled to the light guide plate assembly 1 in a sliding manner, as described above. Due to the repulsive force due to sliding friction between the cover 2 and the light guide plate assembly 1, there is a problem in that the replacement operation cannot be easily performed.

둘째, 상술한 슬라이딩 마찰에 의해 램프 카바(2)가 시트(1a)의 표면에 소정의 손상을 입힘으로써, 빛샘(Light leakage)현상 등의 불량을 발생시키는 문제점이 있다.Second, there is a problem in that the lamp cover 2 causes a predetermined damage to the surface of the sheet 1a by the above-described sliding friction, thereby causing a defect such as a light leakage phenomenon.

따라서, 본 발명의 목적은 도광판 어셈블리를 지지하던 램프 카바의 일부를 제거하여, 도광판 어셈블리의 단면과 맞닿게 하고, 이를 통해 램프 카바 및 도광판 어셈블리간의 마찰면을 최소화함으로써, 램프 어셈블리의 조립성을 향상시킬 수 있도록 하는 LCD 후광장치용 램프 어셈블리 구조를 제공함에 있다.Accordingly, an object of the present invention is to remove a part of the lamp cover that was supporting the light guide plate assembly to abut the end face of the light guide plate assembly, thereby minimizing the friction surface between the lamp cover and the light guide plate assembly, thereby improving the assembly of the lamp assembly. The present invention provides a lamp assembly structure for an LCD backlight device.

상기와 같은 목적을 달성하기 위한 본 발명은 도광판에 적층된 시트를 갖는 도광판 어셈블리와, 상기 도광판 어셈블리에 결합되는 램프 카바와, 상기 램프 카바에 수납되어 램프를 고정시키는 램프 홀더를 포함하는 LCD 후광장치에 있어서, 상기 램프 카바의 일측부는 상기 도광판 어셈블리의 입광부쪽 하부면을 지지하고, 타측부는 상기 도광판 어셈블리의 입광부쪽 상부면에 접하도록 형성되는 것을 특징으로 한다.The present invention for achieving the above object is an LCD backlight device comprising a light guide plate assembly having a sheet laminated to the light guide plate, a lamp cover coupled to the light guide plate assembly, and a lamp holder accommodated in the lamp cover to secure the lamp In one embodiment, the one side of the lamp cover is characterized in that the lower surface of the light guide plate assembly of the light guide plate assembly, the other side is formed to be in contact with the upper surface of the light guide plate side of the light guide plate assembly.

이에 따라, 본 발명에서는 램프 어셈블리의 교체가 용이해진다.Accordingly, in the present invention, the lamp assembly is easily replaced.

이하, 첨부된 도면을 참조하여 본 발명에 따른 LCD 후광장치용 램프 어셈블리 구조를 좀더 상세히 설명하면 다음과 같다.Hereinafter, the lamp assembly structure for an LCD backlight device according to the present invention will be described in detail with reference to the accompanying drawings.

도 2는 본 발명에 따른 LCD 후광장치용 램프 어셈블리 구조를 개략적으로 도시한 사시도이고, 도 3은 이를 개략적으로 도시한 단면도이다.Figure 2 is a perspective view schematically showing a lamp assembly structure for an LCD backlight device according to the present invention, Figure 3 is a schematic cross-sectional view.

도시된 바와 같이, 램프 카바(10)의 일측부(10c)는 상기 도광판 어셈블리(1)의 입광부쪽 하부면을 지지하고, 타측부(10b)는 상기 도광판 어셈블리(1)의 입광부쪽 상부면에 접하도록 형성된다.As shown, one side portion 10c of the lamp cover 10 supports the bottom surface of the light incident portion of the light guide plate assembly 1, and the other side portion 10b is the upper side of the light incident portion of the light guide plate assembly 1. It is formed to be in contact with the surface.

이러한 본 발명을 좀더 상세히 설명한다.This invention is described in more detail.

먼저, 도 2를 참조하면, 본 발명의 램프 어셈블리는 램프 홀더(3)에 의해 고정된 램프(4)와, 램프 홀더(3) 위에 탑재되어 램프(4)를 보호하는 램프 카바(10)로 구성된다.First, referring to FIG. 2, the lamp assembly of the present invention includes a lamp 4 fixed by the lamp holder 3 and a lamp cover 10 mounted on the lamp holder 3 to protect the lamp 4. It is composed.

이때, 본 발명에 따른 램프 카바(10)의 일측부(10c)는 종래의 구조와 마찬가지로 도광판 어셈블리(1)의 하부면을 지지한다. 그러나, 본 발명에 따른 램프 카바(10)의 다른 일측부(10b)는 도광판 어셈블리(1)의 상부면을 지지하던 종래의 구조와 달리, 소정의 길이만큼 제거된 상태로 형성된다.At this time, one side portion 10c of the lamp cover 10 according to the present invention supports the lower surface of the light guide plate assembly 1 as in the conventional structure. However, unlike the conventional structure in which the other side portion 10b of the lamp cover 10 according to the present invention supports the upper surface of the light guide plate assembly 1, it is formed with a predetermined length removed.

이에 따라, 도 3에 도시된 바와 같이, 도광판 어셈블리(1)의 입광부쪽 하부면은 램프 카바(10)의 일측부(10c)에 의해 지지되는 반면에, 도광판 어셈블리(1)의 입광부쪽 상부면은 램프 카바(10)의 일측부(10b)에 지지되지 않고 단지 연접된다.Accordingly, as shown in FIG. 3, the bottom surface of the light guide plate assembly 1 is supported by one side portion 10c of the lamp cover 10, while the light incident plate side of the light guide plate assembly 1 is supported. The upper surface is not supported by the one side portion 10b of the lamp cover 10 but is merely connected.

그 결과, 도광판 어셈블리(1)의 상· 하단부가 램프 카바(2)의 양측부에 전체적으로 물려있던 종래와 달리, 본 발명의 램프 어셈블리가 구비된 후광장치에서는 도광판 어셈블리(1)의 하단부만 램프 카바(10)의 일측부(10c)에 지지되고 상단부는 램프 카바(10)로부터 이탈된다.As a result, unlike the prior art in which the upper and lower ends of the light guide plate assembly 1 are entirely bitten by both sides of the lamp cover 2, in the backlight device with the lamp assembly of the present invention, only the lower end of the light guide plate assembly 1 is attached to the lamp cover. It is supported by one side 10c of 10 and the upper end is separated from the lamp cover 10.

이에 따라, 램프 카바(10) 및 도광판 어셈블리(1)간의 마찰면은 적절히 감소된다.Accordingly, the friction surface between the lamp cover 10 and the light guide plate assembly 1 is appropriately reduced.

이러한 본 발명에 따른 램프 어셈블리가 도광판 어셈블리(1)에 장착되는 과정을 좀더 상세히 설명한다.The process of mounting the lamp assembly according to the present invention on the light guide plate assembly 1 will be described in more detail.

먼저, 작업자는 램프 어셈블리를 해체하여, 노후된 램프(4)를 새로운 램프로 교환한 후에, 램프를 장착한 램프 홀더(3)를 램프 카바(10)에 수납시킨다.First, the operator disassembles the lamp assembly, replaces the old lamp 4 with a new lamp, and then stores the lamp holder 3 with the lamp in the lamp cover 10.

이어서, 도광판 어셈블리(1)의 입광부쪽 하단부가 램프 카바(10)의 일측부(10c)에 의해 지지되도록 배열하고, 이에 대응되는 도광판 어셈블리(1)의 입광부쪽 상단부가 램프 카바(10)의 다른 일측부(10b)에 접하도록 배열한다.Subsequently, the light incident plate lower end portion of the light guide plate assembly 1 is arranged to be supported by one side portion 10c of the lamp cover 10, and the light incident portion upper end portion of the light guide plate assembly 1 corresponds to the lamp cover 10. Arranged to contact the other side of the portion (10b).

이 후, 램프 카바(10)를 도광판 어셈블리(1)에 슬라이딩시켜 램프 어셈블리를 도광판 어셈블리(1)에 장착한다.Thereafter, the lamp cover 10 is slid to the light guide plate assembly 1 to mount the lamp assembly to the light guide plate assembly 1.

이러한 슬라이딩 작용이 이루어질 경우, 본 발명에서는 상술한 구조에 따라 램프 카바(10) 및 도광판 어셈블리(1)간의 마찰이 도광판 어셈블리(1)의 입광부쪽 하단부에서만 제한적으로 발생됨으로써, 마찰에 의한 반발력이 저감될 수 있고, 이에 따라 작업자는 용이한 램프(4) 교환을 달성할 수 있다.When the sliding action is made, according to the present invention, the friction between the lamp cover 10 and the light guide plate assembly 1 is generated only at the lower end of the light incident part side of the light guide plate assembly 1, so that the repulsive force due to friction is increased. Can be reduced, and thus the operator can achieve easy lamp 4 replacement.

한편, 도광판 어셈블리(1)의 하단부를 지지하는 램프 카바(10)의 일측부는 도 3에 도시된 바텀 샤시(Bottom Chassis:7)에 의해 보강된다.Meanwhile, one side of the lamp cover 10 supporting the lower end of the light guide plate assembly 1 is reinforced by a bottom chassis 7 illustrated in FIG. 3.

통상, 램프 카바(10) 및 바텀 샤시(7)간의 갭(Gap)은 매우 극미한 값, 예컨대, 2mm 정도로 유지되는 것이 일반적이므로 이에 따라, 바텀 샤시(7)는 도광판 어셈블리(1)로부터 본 발명의 램프 카바(10)가 이탈되는 것을 적절히 방지한다.Normally, the gap Gap between the lamp cover 10 and the bottom chassis 7 is generally kept at a very small value, for example, about 2 mm, so that the bottom chassis 7 is the present invention from the light guide plate assembly 1. To prevent the lamp cover 10 from being detached.

또한, 본 발명의 램프 카바(10) 인접부에 형성된 몰드 프레임(6)은 램프 어셈블리를 전체적으로 커버링함으로써, 소정의 충격에 의해 램프 카바(10)가 도광판 어셈블리(1)로부터 이탈되는 것을 적절히 방지한다.In addition, the mold frame 6 formed in the vicinity of the lamp cover 10 of the present invention covers the lamp assembly as a whole, thereby appropriately preventing the lamp cover 10 from being separated from the light guide plate assembly 1 by a predetermined impact. .

이와 같이, 본 발명에서는 상술한 구조를 통해 램프 카바(10) 및 도광판 어셈블리(1)간의 마찰면을 최소화시킴과 아울러 바텀 샤시(7) 및 몰드 프레임(6)을 통한 보강에 의해 램프 카바(10)의 장착상태를 적절히 유지시킴으로써, 램프 교환이 쉽고, 빠르게 이루어질 수 있도록 한다.As described above, in the present invention, the friction cover between the lamp cover 10 and the light guide plate assembly 1 is minimized through the above-described structure, and the lamp cover 10 is reinforced by the bottom chassis 7 and the mold frame 6. By properly maintaining the mounting state of the lamp), the lamp can be replaced easily and quickly.

또한, 본 발명에서는 상술한 구조를 통해 램프 커버(10) 및 시트(1a)간의 마찰현상을 미연에 제거함으로써, 빛샘현상 등의 불량발생을 적절히 억제시킬 수 있다.Further, in the present invention, by removing the friction phenomenon between the lamp cover 10 and the sheet 1a through the above-described structure, it is possible to appropriately suppress the occurrence of defects such as light leakage.

이러한 본 발명은 생산라인에서 제조되어지는 전 기종의 LCD 장치에서 두루 유용하다.The present invention is useful in all types of LCD devices that are manufactured in production lines.

그리고, 본 발명의 특정한 실시예가 설명 및 도시되었지만 본 발명이 당업자에 의해 다양하게 변형되어 실시될 가능성이 있는 것은 자명한 일이다.And while certain embodiments of the invention have been described and illustrated, it will be apparent that the invention may be embodied in various modifications by those skilled in the art.

이상에서, 상세히 설명한 바와 같이, 본 발명에 따른 LCD 후광장치용 램프 어셈블리 구조에서는 도광판 어셈블리를 지지하던 램프 카바의 일부를 제거하여, 도광판 어셈블리의 단면과 맞닿게 하고, 이를 통해 램프 카바 및 도광판 어셈블리간의 마찰면을 최소화함으로써, 램프 어셈블리의 조립성을 향상시킬 수 있다.As described above, in the lamp assembly structure for the LCD backlight device according to the present invention, a part of the lamp cover supporting the light guide plate assembly is removed to be brought into contact with the end face of the light guide plate assembly, and thus, between the lamp cover and the light guide plate assembly.
