Abstract

본 발명은 투사형 화상표시장치에 관한 것으로서, 더욱 상세하게는 투사형 화상표시 장치의 램프에 발생된 열을 방출시키는 팬이 구동할 수 있는 전원을 선택적으로 공급하는 투사형 화상표시장치의 팬 구동용 전원 공급장치에 관한 것이다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a projection image display device, and more particularly, to supply a fan driving power supply of a projection image display device selectively supplying power that can be driven by a fan that emits heat generated by a lamp of a projection image display device. Relates to a device.

이를 위하여 본 발명은, 입력되는 전원을 공급하는 전원 공급부(10)와, 작동중에 발생하는 열에 의한 기기 내부의 온도를 감지한 온도 감지신호를 출력하는 온도 감지부(22)와, 상기 온도 감지부(22)에서 출력되는 온도 감지 신호에 대응하도록 팬의 구동을 제어하는 팬 구동부(l8)로 구성되는 팬 구동 제어장치로서, 축전지(210)와; 정전 여부에 따라 전원 공급을 일정 시간동안 선택적으로 공급하도록 제어하는 정정 판단부(200)와; 정전판단부(200)의 제어에 따라 선택적으로 구동되어 상기 전윈 공급부(10)의 전윈과 상기 축전지(210)의 전원을 선택적으로 상기 팬 구동부(18)에 공급하는 제2 스위칭부(220)를 더 포함하로써, 전원 오프되는 경우에도 팬을 구동시킬 수 있는 효과가 있다.To this end, the present invention, the power supply unit 10 for supplying the input power, a temperature sensor 22 for outputting a temperature detection signal for detecting the temperature inside the device by the heat generated during operation, and the temperature sensor A fan drive control device comprising a fan drive unit (8) for controlling the drive of a fan so as to correspond to a temperature sensing signal output from the (22), comprising: a storage battery (210); A correction determination unit 200 which controls to selectively supply power supply for a predetermined time depending on whether there is a power failure; A second switching unit 220 selectively driven under the control of the electrostatic determination unit 200 to selectively supply the electric power of the electric power supply unit 10 and the power of the storage battery 210 to the fan driving unit 18. In addition, there is an effect that can drive the fan even when the power off.
