일반적으로 투과형 박막 액정표시소자를 이용하여 화상을 전방의 스크린에 투사시키는 액정프로젝터는 백색광을 방출하는 램프(1)와, 이 백색광으로부터 청색광, 녹색광 및 적색광을 선별적으로 투과시키는 복수의 반투과형 미러(2)(3)와, 이들 선별된 광들을 전반사시키는 전반사 미러(4)(5)(6)와, 복수의 액정표시소자(7)(8)(9)와, 선별된 광들을 접속하여 투사시키는 렌즈조립체(10)가 소정배열로 배치된 구조를 가진다.In general, a liquid crystal projector for projecting an image onto a front screen by using a transmissive thin film liquid crystal display device includes a lamp (1) for emitting white light and a plurality of semi-transmissive mirrors for selectively transmitting blue light, green light and red light from the white light. (2) (3), a total reflection mirror (4) (5) (6) which totally reflects the selected lights, a plurality of liquid crystal display elements (7) (8) (9), and the selected lights The lens assembly 10 to be projected has a structure arranged in a predetermined arrangement.
그런데, 상기와 같은 종래의 액정프로젝터에서는 광을 방출하는 램프(1)가 후방측에 배치되고 방출된 광을 집속하는 렌즈조립체(10)가 전방측에 배치됨으로써, 램프(1)로부터 방출되는 열에너지를 시청자측으로 방출시켜야 한다. 이에 따라서 시청 환경이 저하되고 따라서 시청범위가 축소되고, 제품이 대형화된다는 문제점이 있다.However, in the conventional liquid crystal projector as described above, the lamp 1 for emitting light is disposed at the rear side and the lens assembly 10 for focusing the emitted light is disposed at the front side, whereby the heat energy emitted from the lamp 1 is emitted. Should be emitted to the viewer. Accordingly, there is a problem that the viewing environment is lowered, thus the viewing range is reduced, and the product is enlarged.
이러한 문제점에 따라 제안된 것이 제2도 및 제3도에 도시된 바와 같은 액정프로젝터이다. 이는 램프(30)를 렌즈조립체(20)에 인접시켜서 구성된 것으로서, 램프(30)로부터 방출되는 열에너지를 팬(35)으로 전방측으로 방출시키고 장치를 소형화하여 상기와 같은 문제점을 해결한다. 참조번호 45는 램프(30)를 내부에 수용하는 램프 하우징이다.Proposed in accordance with this problem is a liquid crystal projector as shown in FIG. 2 and FIG.

Here, the coupling member 60 is coupled to the chassis member 50, the pin 52, the other end is fixed to the chassis member 50, the screws (53, 53 '). At the time of disassembly of the screws 53 and 53 ', the screw 52 is rotated by the self-weight of the coupling member 60 about the pin 52.
그리고 상기 램프 하우징(70)에는 결합부재(60)로부터 취출이 용이하도록 그 전면부에 손잡이부(71)를 형성하였다.And the lamp housing 70 has a handle portion 71 formed on the front portion to facilitate taking out from the coupling member (60).
한편, 상기 결합부재(60)의 회전범위를 제한시키는 제한수단을 더 구비하였는 바, 이 제한수단은 상기 새시부재(50)의 내측면에 소정각도로 경사진 경사턱(55)(56)을 형성하여서, 상기 결합부재(60)의 하면이 경사턱(55)(56)에 접촉시 회전정지되도록 하였다. 미설명 부호 100은 커넥터로서, 램프 하우징(70)을 결합부재(60)에 결합함과 동시에 새시부재(50) 내측에 설치된 단자(미도시)에 직접적으로 연결된다.On the other hand, it further provided with a limiting means for limiting the rotation range of the coupling member 60, the limiting means is inclined jaw (55) 56 inclined at a predetermined angle on the inner surface of the chassis member (50) By forming, the lower surface of the coupling member 60 is stopped rotationally in contact with the inclined jaw (55, 56). Reference numeral 100 is a connector, which is coupled directly to the terminal (not shown) installed inside the chassis member 50 while coupling the lamp housing 70 to the coupling member 60.
이와 같이 소형화를 위해서 렌즈 조립체(90)와 램프(80)가 인접설치된 액정프로젝터에 있어서는, 먼저 램프(80)를 램프 하우징(70)에 수용시키고 이 램프 하우징(70)을 결합부재(60)에 결합하여 나사(72)(72')고정시킨다. 이어서 이 결합부재(60)를 새시부재(50)에 핀(52)결합 및 나사(53)(53')고정시킨 후 렌즈 조립체(90)를 조립한다. 이는 제5도 및 제6도에 도시된 바와 같이 결합부재(60)와 렌즈 조립체(90)가 상호 간섭되기 때문이다. 즉, 렌즈 조립체(90)의 선단부가 제6도에 도시된 바와 같이 결합부재(60)의 진입로 상에 위치되기 때문이다.In this case, in the liquid crystal projector in which the lens assembly 90 and the lamp 80 are adjacent to each other for miniaturization, the lamp 80 is first accommodated in the lamp housing 70 and the lamp housing 70 is coupled to the coupling member 60.

램프(80)의 청소 및 교환을 위하여 램프(80)를 분리시키고자 할시에는 먼저, 액정프로젝터의 프론트 캐비넷(110)을 해체시키고, 나사(53)(53')를 해체하여서 결합부재(60)를 핀(52)을 중심으로 제6도에 점선으로 도시된 바와 같이(점선으로 표시) 하방으로 회전시킨다. 이때 결합부재(60)는 자중에 의해서 회전될 수 있으며, 상기 렌즈 조립체(90)와 간섭되지 않고 회전될 수 있으며, 경사턱(55)(56)에 결합부재(60)의 하면이 접촉되면서 회전이 정지되게 된다. 이어서 나사(72)(72')를 해체하고 손잡이부(71)를 잡아 당겨 램프 하우징(70)을 결합부재(60)로부터 취출시킨다. 최종으로 램프(80)를 램프 하우징(70)으로부터 꺼내어 청소 및 교환한다.When the lamp 80 is to be separated for cleaning and replacing the lamp 80, first, the front cabinet 110 of the liquid crystal projector is dismantled, and the coupling member 60 is dismantled by disassembling the screws 53 and 53 '. Rotate downward about pin 52 as shown by the dotted line in FIG. 6 (indicated by dashed lines). In this case, the coupling member 60 may be rotated by its own weight, and may be rotated without interfering with the lens assembly 90. The coupling member 60 may rotate while the lower surface of the coupling member 60 contacts the inclined jaws 55 and 56. Will be stopped. Subsequently, the screws 72 and 72 'are disassembled and the handle 71 is pulled out to take out the lamp housing 70 from the coupling member 60. Finally, the lamp 80 is taken out of the lamp housing 70 and cleaned and replaced.
이상에서 설명한 바와 같이 본 고안은 렌즈 조립체(90)를 해체하지 않고도 램프(80)의 분리작업을 간편하게 하는 이점을 가진다. 즉, 결합부재(60)를 회전가능하게 하여서 회전시 렌즈 조립체(90)와 간섭되지 않고 회전되게 함으로써 렌즈 조립체(90)를 분리하지 않고도 램프(80)를 분리할 수 있게 한다.As described above, the present invention has an advantage of simplifying the detaching operation of the lamp 80 without disassembling the lens assembly 90. That is, the coupling member 60 can be rotated so that the lamp 80 can be detached without removing the lens assembly 90 by rotating without causing interference with the lens assembly 90.
상술한 바와 같이 본 고안은 램프의 교환작업 공수를 대폭 감소시키는 액정프로젝터의 램프 결합장치를 제공한다.As described above, the present invention provides a lamp coupling device of a liquid crystal projector which greatly reduces the number of replacement work of a lamp.
