본 고안은 컬러 TV의 전원구동 표시회로에 관한 것으로 특히, 리모콘 컬러 TV에서 TV가 대기(stand-by)전원상태에 있는 것을 표시하기 위한 컬러 TV의 전원구동 표시회로에 관한 것이다.The present invention relates to a power drive display circuit of a color TV, and more particularly, to a power drive display circuit of a color TV for displaying that the TV is in a stand-by power state in a remote control color TV.

종래에는 제2도에 도시한 바와같이 리모콘 대기전원(5V) 라인단자(212)에서 공급되는 전압에 의해 다이오드(D22)와 저항(R21)(R22)을 통해 발광다이오드(D25)가 동작하여 리모콘 대기전원을 표시하였고, 또한 메인전원 동작시 전원(12V) 라인단자(211)를 통해서 공급되는 전원이 다이오드(D23)와 저항(R23)을 거쳐 발광다이오드(D24)를 동작시켜 메인전원 공급을 표시하였다.Conventionally, the light emitting diode through the diode (D 22) and a resistor (R 21) (R 22) by the second diagram the voltage supplied from the remote control to the standby power supply (5V) line terminal 212, as shown in (D 25) The remote control standby power is displayed, and when the main power is operated, the power supplied through the power supply (12V) line terminal 211 passes through the diode D 23 and the resistor R 23 to operate the light emitting diode D 24 . The operation was performed to indicate the main power supply.

그러나 상기와 같은 리모콘 대기전원과 메인전원 표시가 분리되어 있어 발광다이오드가 2개 필요하고 매인보드에서 12V의 전원공급라인이 별도로 연결되어야 하는 불편함이 있었다.However, since the remote controller standby power and the main power display are separated, two light emitting diodes are required and a 12V power supply line is separately connected to the main board.

본 고안은 상기와 같은 문제점을 해결하기 위하여 안출한 것인바, 리모콘 대기전원과 메인전원이 공급되는 것을 스위칭하는 릴레이에 트랜지스터와 저항을 연결하여 전원의 온/오프신호에 의해 전원공급표시 발광다이오드의 밝기를 조정하여 상기 두가지 전원공급상태를 표시하도록 한 것으로 이하 첨부된 도면에 의하여 본고안을 상세히 설명하면 다음과 같다.The present invention has been made to solve the above problems, by connecting a transistor and a resistor to a relay for switching the standby power supply and the main power supply to the remote control of the power supply display light emitting diode by the on / off signal of the power supply The present invention will be described in detail with reference to the accompanying drawings so as to display the two power supply states by adjusting the brightness as follows.

제1도는 본 고안의 회로도로서 교류전원입력 플러그(100)는 메인전원 스위치부(101)에 접속하고 사익 메인 전원 스위치부(101)는 메인회로부(102)와 리모콘 대기전원부(103)에 접속하되 상기 리모콘 대기전원부(103)는 전원스위치(105)가 연결된 마이컴 집적회로(104)에 접속한다.1 is a circuit diagram of the present invention, the AC power input plug 100 is connected to the main power switch unit 101 and the sound main power switch unit 101 is connected to the main circuit unit 102 and the remote control standby power supply unit 103. The remote control standby power supply 103 is connected to the microcomputer integrated circuit 104 to which the power switch 105 is connected.

상기 메인전원 스위치부(101)와 리모콘 대기전원부(103) 및 마이컴 집적회로(104)에 접속된 메인전원 스위칭용 릴레이 회로(110)는 릴레이(111)에 트랜지스터(TR1)와 전원(B+)에 연결된 저항(RL1)으로 구성하고 상기리모콘 대기전원부(103)와 릴레이회로(110)에 접속된 전원표시회로(120)는 트렌지스터(TR2)와 발광다이오드(D2)에 전원(V+)이 연결된 저항(R2-R7)과 다이오드(D1)로 구성한다.The main power switching relay circuit 110 connected to the main power switch unit 101, the remote controller standby power supply unit 103, and the microcomputer integrated circuit 104 includes a transistor TR 1 and a power supply B + to the relay 111. The power display circuit 120, which is composed of a resistor RL 1 connected to the power supply unit 103 and connected to the remote standby power supply unit 103 and the relay circuit 110, supplies power to the transistor TR 2 and the light emitting diode D 2 . + ) Consists of connected resistor (R 2 -R 7 ) and diode (D 1 ).

이하 이들의 작용효과를 설명한다.The effect of these will be described below.

제1도에서 플러그(100)를 통하여 교류전원이 입력되면 이 전원은 메인전원 스위치부(101)를 통해 리모콘대기 전원부(103)가 동작하여 릴레이회로(110)의 릴레이를 구동할 수 있는 전압(B+)이 저항(R1)을 통하여 콘덴서(C1)에 충전된다.When the AC power is input through the plug 100 in FIG. 1, the power is supplied to a voltage capable of driving the relay of the relay circuit 110 by operating the remote controller standby power supply 103 through the main power switch 101. B + ) is charged to the capacitor C 1 through the resistor R 1 .

이때 상기 리모콘 대기전원부(103)에서 출력된 전압(5V)이 전원표시회로(120)의 다이오드(D1)와 저항(R3)(R5)을 통하여 전원표시 발광다이오드(D2)에 인가되어 상기 발광다이오드(D2)가 발광된다.At this time, the voltage 5V output from the remote standby power supply 103 is applied to the power display LED D 2 through the diode D 1 and the resistor R 3 (R 5 ) of the power display circuit 120. The light emitting diode D 2 emits light.

한편 마이컴(104)에 연결되어 있는 전원스위치(105)를 누르면 그때까지 대기상태에 있던 마이컴(104)이 동작하여 전원컨트롤단(PC)에 하이전압이 출력되고 이 하이전압은 릴레이회로(110)내의 저항(R4)을 통하여 트랜지스터(TR1)의 베이스에 인가되므로 상기 트랜지스터(TR1)는 온되어 저항(R1)에 접속된 전원(B+)이 릴레이(111)에 흘러 상기 릴레이(111)가 동작된다.On the other hand, when the power switch 105 connected to the microcomputer 104 is pressed, the microcomputer 104 in the standby state is operated until then, a high voltage is output to the power control terminal PC, and the high voltage is relay circuit 110. because through in the resistance (R 4) applied to the base of the transistor (TR 1), it said transistor (TR 1) is to flow the relay in the on-state resistance (R 1) a power supply (B +), relay 111 is connected to the ( 111 is operated.

상기 릴레이(111)의 구동에 의해 메인전원이 TV 세트에 공급되고 TV가 동작하여 화면이 나타나게 된다. 이때 상기 온된 트랜지스터(TR1)의 콜렉터에 전원이 떨어지고 이 전원이 떨어짐으로써 전원표시회로(120)의 저항(R2)을 통하여 트랜지스터(TR2)가 온되며 상기 트랜지스터(TR2)의 온됨으로 인하여 전원전압(V+)이 저항(R7)(R6)(R5)을 통하여 발광다이오드(D2)에 더 많은 전류를 흘리게 되어 상기 발광다이오드(D2)는 더욱 밝게 발광된다.The main power is supplied to the TV set by the driving of the relay 111, and the TV is operated to display a screen. The on-doemeuro the ondoen transistor (TR 1) of the power falling on the collector, the power is falling as is the transistor (TR 2) via the resistor (R 2) of the power supply display circuit 120 on the transistor (TR 2) Due to the power supply voltage (V + ) flows more current through the resistor (R 7 ) (R 6 ) (R 5 ) to the light emitting diode (D 2 ), the light emitting diode (D 2 ) is emitted more brightly.

여기에서 초기 전원에 의해 구동될때의 전류보다 메인 전원이 구동된 후의 전류를 몇배정도 크게하면 두상태의 변화를 확실하게 구분할 수 있다.Here, if the current after the main power is driven several times larger than the current when the initial power is driven, the change of the two states can be clearly distinguished.

이상에서 설명한 바와같이 전원표시 발광다이오드를 한개만 사용하여 리모콘 대기전원 표시상태에서는 발광다이오드의 전압을 낮게하고 메인전원 동작시에는 전압을 높게하여 발광율을 변화시켜 효과적으로 전원표시를 구분할 수 있는 장점이 있는 것이다.As described above, by using only one power display light emitting diode, the voltage of the light emitting diode is decreased in the standby power display state of the remote controller, and the voltage is increased in the operation of the main power supply to change the emission rate to effectively distinguish the power display. It is.
