Description

고정수단을 갖는 백라이트유닛{Back Light Unit Having a Fixing Means}Back light unit having a fixing means

본 고안은 고정수단을 갖는 백라이트유닛에 관한 것으로써, 보다 상세하게는 백라이트유닛 조립시 그 내부에 설치되는 램프유닛을 동시에 밀착 고정할 수 있도록 한 고정수단을 갖는 백라이트유닛에 관한 것이다.The present invention relates to a backlight unit having a fixing means, and more particularly to a backlight unit having a fixing means that can be fixed at the same time close to the lamp unit installed in the backlight unit assembly.

일반적으로 액정표시장치(LCD; Liquid Crystal Display)는 자가적으로 광을 발산하는 장치가 아니므로 액정표시패널(Panel)의 배면에 백라이트유닛(Back Light Unit)을 설치한다.In general, since a liquid crystal display (LCD) is not a device that emits light by itself, a backlight unit is installed on a rear surface of a liquid crystal display panel.

도 1을 참조로 하면, 액정표시장치(190)는 백라이트유닛(70) 상부에 액정표시패널(40)과 탑섀시(30, Top Chassis)를 이용하여 이들을 결합함으로써 구성된다.Referring to FIG. 1, the liquid crystal display device 190 is configured by using a liquid crystal display panel 40 and a top chassis 30 on the backlight unit 70 to combine them.

이때, 백라이트유닛(70)은 하부프레임(120)상에 액정표시패널(30)로 광을 공급하기 위한 램프를 포함하는 램프유닛(130)과, 반사판(미도시)과 도광판(60) 및 다수매의 광학시트(50)가 차례로 설치되고, 그 상부에 상부프레임(100)이 결합된다.In this case, the backlight unit 70 includes a lamp unit 130 including a lamp for supplying light to the liquid crystal display panel 30 on the lower frame 120, a reflector (not shown), a light guide plate 60, and a plurality of lamps. The sheet optical sheet 50 is installed in sequence, the upper frame 100 is coupled to the upper.

그리고, 상부프레임(100)상에 액정표시패널(40)이 적층되고, 탑섀시(30)로 커버함으로써 조립이 완료된다.Then, the liquid crystal display panel 40 is stacked on the upper frame 100 and covered with the top chassis 30 to complete the assembly.

여기서, 도 2a 및 도 2b를 참조로 하여, 종래의 고정수단을 이용한 백라이트유닛의 상부프레임과 하부프레임의 조립방법을 구체적으로 설명하도록 한다.2A and 2B, a method of assembling the upper frame and the lower frame of the backlight unit using the conventional fixing means will be described in detail.

The assembly is completed by coupling through a coupling means (not shown).

여기서, 램프유닛(130)은 하부프레임(120) 양측부를 통해 슬라이딩 삽입되고, 그 상태에서 유동이 발생하는 것을 방지하기 위해 고정나사(10)를 이용해 램프유닛(130)의 관통홀(132)을 통과시켜 상부프레임(100)의 나사홀(110)에 끼워 고정한다.Here, the lamp unit 130 is slidingly inserted through both sides of the lower frame 120, the through-hole 132 of the lamp unit 130 using the fixing screw 10 to prevent the flow from occurring in that state. Passed through and screwed into the screw hole 110 of the upper frame (100).

따라서, 상기와 같이 램프유닛(130)을 고정하기 위해 스크류볼트등이 고정나사(10)를 이용하여 고정하는 경우, 작업자가 수작업으로 수행해야하므로 작업공정이 증가되는 것은 물론이고, 그로인해 조립비용이 상승되는 문제점이 있었다.Therefore, when fixing the screw bolt, etc. using the fixing screw 10 to fix the lamp unit 130 as described above, since the worker must be performed manually, the work process is increased, and thereby the assembly cost There was this rising issue.

또한, 상기와 같이 작업공정이 증가함으로써 작업시간의 증대, 불필요한 노동력 투입으로 인한 생산비용이 증가되는 문제점이 있었다.In addition, as the work process increases as described above, there is a problem that the production cost is increased due to the increase of working time and unnecessary labor input.

따라서, 본 고안은 상기와 같은 문제점을 해결하기 위하여 안출된 것으로써, 본 발명의 목적은 상부프레임과 하부프레임 결합시, 그 내부에 설치되는 램프유닛을 동시에 지지할 수 있도록 후크등의 고정수단을 통해 결합함으로써, 작업시간 단축 및 조립비용을 절감시키도록 한 고정수단을 갖는 백라이트유닛을 제공하는데 있다.Therefore, the present invention is devised to solve the above problems, an object of the present invention is to provide a fixing means such as a hook so as to simultaneously support the lamp unit installed therein when the upper frame and the lower frame is combined; By combining through, to provide a backlight unit having a fixing means to reduce the working time and assembly cost.
