케이싱(100)에 의해 전체적인 외관이 형성되며, 케이싱 내부에는 전장품이 마련된다. 케이싱(100)의 전면 상부에는 광투과형 스크린(600)이 설치되며, 내부에는 영상투영원(400)과, 이 영상투영원(400)에서의 투영광을 스크린(600)을 향하여 굴절반사시키는 투영미러(500), 케이싱(100) 내부의 소정의 위치에는 조명기기(900)가 배치된다. 여기서, 조명기기(900)는 스크린(600)의 배면 중 전장품이 위치되지 않는 소정의 위치에 배치되는 것이 바람직하다. 또한, 케이싱(100)의 외부에는 사용자가 조명기기(900)의 점멸동작을 스위칭하도록 스위치(800)가 마련된다. 케이싱(100)은 착탈 가능한 전,후방케이싱(100)(110) 및 베이스(120)로 분리 구성된다.The overall appearance is formed by the casing 100, and the electrical equipment is provided inside the casing. A light transmissive screen 600 is installed on an upper portion of the front surface of the casing 100, and an image for refractively reflecting the projection light from the image projection source 400 and the projection light from the image projection source 400 toward the screen 600. The lighting device 900 is disposed at a predetermined position inside the mirror 500 and the casing 100. Here, the lighting device 900 is preferably disposed at a predetermined position in which the electrical equipment is not located on the rear surface of the screen 600. In addition, the switch 800 is provided outside the casing 100 so that the user switches the flashing operation of the lighting device 900. The casing 100 is detachably configured to be detachable front and rear casings 100 and 110 and the base 120.

도 4는, 도 3에 도시된 조명기능을 갖는 프로젝션 텔레비젼의 동작을 설명하기 위한 블록도로서, 프로젝션 텔레비젼이 조명장치로 사용되는 경우에 동작되는 부분 블록도를 나타낸 것이다.Fig. 4 is a block diagram for explaining the operation of the projection television having the illumination function shown in Fig. 3, which shows a partial block diagram that is operated when the projection television is used as the lighting apparatus.

조명기능을 갖는 프로젝션 텔레비젼은, 전원공급부(500), 스위치(800), 조명기기(900), 광투과형 스크린(600), 제어부(700) 등을 가지고 있다.A projection television having an illumination function includes a power supply unit 500, a switch 800, an illuminator 900, a light transmissive screen 600, a control unit 700, and the like.

전원공급부(500)는 프로젝션 텔레비젼의 전체 시스템에 전원을 공급하며, 일반적으로 외부 DC전원(220V)을 공급받는다.The power supply unit 500 supplies power to the entire system of the projection television, and is generally supplied with an external DC power supply 220V.

스위치(800)는 케이싱(100)의 외부에 마련되며, 사용자가 조작하기 편리한 소정위치에 마련된다. 스위치(800)는 케이싱(100)내부에 마련된 조명기기(900)의 점멸동작을 스위칭한다.The switch 800 is provided outside the casing 100 and is provided at a predetermined position that is convenient for the user to operate. The switch 800 switches the flashing operation of the lighting device 900 provided in the casing 100.

조명기기(900)는 일반적인 조명장치에 사용되는 전구로, 백열전구 등이 사용된다.The lighting device 900 is a light bulb used for a general lighting device, and an incandescent lamp is used.

제어부(700)는 스위치(800)의 스위칭동작에 대응하여 조명기기(900)에 전원을 공급하도록 전원공급부(500)를 제어한다. 여기서, 제어부(700)는 프로젝션 텔레비젼이 턴 온상태에서는 조명기기(900)에 전원을 공급하지 않도록 전원공급부(500)를 제어한다.The control unit 700 controls the power supply unit 500 to supply power to the lighting device 900 in response to the switching operation of the switch 800. Here, the control unit 700 controls the power supply unit 500 so as not to supply power to the lighting device 900 when the projection television is turned on.

즉, 프로젝션 텔레비젼이 턴 온상태인 경우에 스위치(800)가 조명기기(900)를 점등시키도록 스위칭되어도 조명기기(900)로 전원을 공급하지 못하도록 제어부(700)는 전원공급부(500)를 차단시킨다. 따라서, 프로젝션 텔레비젼이 조명장치로 사용될 때는, 프로젝션 텔레비젼이 턴 오프상태일 경우에만 가능하게 된다.That is, when the projection television is turned on, the control unit 700 cuts off the power supply unit 500 such that the switch 800 does not supply power to the lighting device 900 even when the switch 800 is switched to turn on the lighting device 900. Let's do it. Therefore, when the projection television is used as the lighting device, it becomes possible only when the projection television is turned off.

조명기기(900)가 점등되면, 광투과형 스크린(600)을 통해서 빛이 투과됨에 따라 간접조명으로 사용가능하게 된다.When the lighting device 900 is turned on, as light is transmitted through the light transmissive screen 600, the lighting device 900 may be used as indirect lighting.

이와 같은 조명기기가 내장된 프로젝션 텔레비젼을 사용함으로써 별도의 조명장치를 마련하지 않아고, 조명장치의 효과를 얻을 수 있다.By using such a projection television with a built-in lighting device, it is possible to obtain an effect of the lighting device without providing a separate lighting device.

본 발명에 따르면, 프로젝션 텔레비젼에 별도의 조명기능을 추가하여, 프로젝션 텔레비젼이 턴-오프상태일때 조명장치로 사용한다.According to the present invention, a separate lighting function is added to the projection television to be used as an illumination device when the projection television is turned off.

따라서, 별도의 조명장치 없이 야간조명, 무드 조명 등의 조명장치의 효과를 얻을 수 있다.Therefore, it is possible to obtain the effect of a lighting device such as night lighting, mood lighting without a separate lighting device.

이상에서는 본 발명의 바람직한 실시예에 대해서 도시하고 설명하였으나, 본 발명은 상술한 특정의 실시예에 한정되지 아니하며, 청구범위에서 청구하는 본 발명의 요지를 벗어남이 없이 당해 발명이 속하는 기술분야에서 통상의 지식을 가진 자라면 누구든지 다양한 변형 실시가 가능한 것은 물론이고, 그와 같은 변경은 청구범위 기재의 범위 내에 있게 된다.Although the preferred embodiments of the present invention have been illustrated and described above, the present invention is not limited to the specific embodiments described above, and the present invention is not limited to the specific embodiments of the present invention without departing from the spirit of the present invention as claimed in the claims.
