이와 같은 목적을 달성하기 위한 본 고안은 신호를 수신하기 위한 신호수신부와, 상기 수신된 신호를 소정레벨로 증폭하기 위한 증폭부와, 상기 증폭부의 출력레벨에 따라 스위칭되는 스위칭부와, 상기 스위칭부의 스위칭에 따라 구동되어 LED가 발광되게 하는 구동부를 포함하여 구성함을 특징으로 한다.The present invention for achieving the above object is a signal receiving unit for receiving a signal, an amplifier for amplifying the received signal to a predetermined level, a switching unit for switching according to the output level of the amplifying unit, the switching unit It is characterized in that it comprises a drive unit for driving according to the switching to emit LED.
이하, 본 고안의 실시예를 첨부된 도면을 참고로 하여 상세히 설명하면 다음과 같다.Hereinafter, with reference to the accompanying drawings, an embodiment of the present invention in detail as follows.
도 1은 본 고안의 회로도로, 다이오드(D1)(D2),저항(R1-R3)으로 구성되어 입력되는 신호를 수신하는 신호수신부(10)와, 상기 신호수신부(10)를 통하여 수신된 신호를 소정레벨로 증폭하는 오피앰프(OP1)로 구성된 증폭부(20)와, 상기 증폭부(20)에 의해 증폭된 신호 레벨에 따라 스위칭되는 트랜지스터(Q1) 및 저항(R4)으로 구성된 스위칭부(30)와, 상기 스위칭부(30)가 스위칭될 때 구동되어 LED의 빛을 발광하게 하는 LED구동IC(41) 및 저항(R5)으로 된 구동부(40)로 구성된 것이다.1 is a circuit diagram of the present invention, which is composed of a diode D1 (D2) and a resistor (R1-R3), and receives a signal received from the signal receiving unit 10 and the signal received through the signal receiving unit 10. Amplification unit 20 comprising an op amp OP1 for amplifying the signal to a predetermined level, and a switching unit consisting of a transistor Q1 and a resistor R4 switched according to the signal level amplified by the amplifying unit 20 ( 30 and an LED driver IC 41 that is driven when the switching unit 30 is switched to emit light of the LED, and a driver unit 40 formed of a resistor R5.
이와 같이 구성된 본 고안의 작용을 설명하면 다음과 같다.Referring to the operation of the present invention configured as described above are as follows.
먼저, 상대방으로부터 전화가 걸려올 경우, 안테나를 통하여 신호가 수신되는데 이때 순간적으로 발생하는 미세한 전파를 수신부(10)에서 감지하게 된다.First, when a call is received from the other party, a signal is received through an antenna, and at this time, the reception unit 10 detects a minute radio wave that occurs momentarily.
따라서, 수신부(10)에서는 감지된 전압과 입력전압으로부터 인가받은 전원을 함께 증폭단에 입력시키게 된다.Therefore, the receiver 10 inputs the sensed voltage and the power applied from the input voltage to the amplifier stage together.
그러면 오피앰프(OP1)로 구성된 증폭부(20)에서는 입력되는 미세한 신호를 큰 신호로 증폭하게 된다.Then, the amplifying unit 20 configured of the op amp OP1 amplifies the input minute signal into a large signal.
여기서, 오피앰프(OP1)는 입력단의 차동전압 차이를 이용하여 최대한 전압차가 나도록 전원을 인가시켜주고 수신부에서 들어오는 전압을 증폭시킨다.Here, the operational amplifier OP1 applies power to the maximum voltage difference by using the differential voltage difference between the input terminals and amplifies the voltage received from the receiver.
한편, 상기 증폭부(20)에 의해 증폭된 신호는 스위칭부(30)의 저항(R4)을 통하여 트랜지스터(Q1)의 베이스에 입력되는데 이때 베이스로 입력되는 전압은 0.7V이상이 되므로 트랜지스터(Q1)를 스위칭 온시키게 된다.Meanwhile, the signal amplified by the amplifier 20 is input to the base of the transistor Q1 through the resistor R4 of the switching unit 30. At this time, the voltage input to the base becomes 0.7 V or more, so that the transistor Q1 ) To switch on.
따라서, 트랜지스터(Q1)가 스위칭 온되면, 구동부(40)의 LED구동IC(41)가 구동되어 LED를 구동시키게 된다.Therefore, when the transistor Q1 is switched on, the LED driver IC 41 of the driver 40 is driven to drive the LED.
즉, 상대방으로부터 전화 신호가 입력될 때마다 휴대폰에 장착된 LED가 발광을 하게 되어 사용자는 신호가 수신되고 있음을 용이하게 파악할 수 있게 되는 것이다.That is, each time a telephone signal is input from the other party, the LED mounted on the mobile phone emits light so that the user can easily recognize that the signal is being received.
이상에서 설명한 바와같은 본 고안은 휴대폰에 별도의 발광장치를 장착하여 상대방으로부터 신호가 입력될 때마다 LED가 발광하게 하므로 신호의 수신여부를 용이하게 알 수 있는 효과가 있다.The present invention as described above is equipped with a separate light emitting device in the mobile phone so that the LED emits light every time a signal is input from the other party, there is an effect that can easily know whether the signal is received.
