도 3을 참조하면, 태양전지121은 태양광에너지를 직접 전기로 변환시킨다. 또한 상기 태양전지121은 200lux에서 3V 35mA의 전원을 발생시킨다. 또한 상기 태양전지21은 수은전지 및 재충전 가능한 배터리가 사용된다. 배터리123은 상기 태양전지121을 통해 얻은 전류가 저장된다. 또한 상기 배터리123은 14V 30mA의 전류가 충전가능하며, 수은전지 및 재충전 가능한 배터리가 사용된다. 다이오드122는 상기 배터리123에 저장된 전류가 역류되는 것을 방지한다. 파워스위치124는 TV 모드 수행 시 증폭기128을 동작시킨다. 상기 파워스위치124가 작동되면 상기 배터리123에 저장된 전류는 증폭기128을 동작시켜 안테나110으로 부터 입력된 신호를 증폭한다. 바이패스 필터125는 상기 파워스위치124의 작동으로 출력되는 상기 배터리123의 DC전류에서 리플(ripple)전류를 제거하여 패스시킨다. 여기서 전원단의 RC쪽 즉, 바이패스 필터125와 저항은 안테나 신호와 관계없이 증폭기(128) 전원단의 전원안정화를 위해 구현된 것으로, 안테나(110)에서 수신된 신호에는 어떠한 영향도 주지 않으므로 상기 수신 신호는 RC time constant에 따른 시간영역 변화와 주파수 영역에서의 변화가 없게 된다.Referring to FIG. 3, the solar cell 121 directly converts solar energy into electricity. In addition, the solar cell 121 generates a power of 3V 35mA at 200lux. In addition, the solar cell 21 is a mercury cell and a rechargeable battery. The battery 123 stores the current obtained through the solar cell 121. In addition, the battery 123 may be charged with a current of 14 V 30 mA, and a mercury cell and a rechargeable battery are used. The diode 122 prevents the current stored in the battery 123 from flowing back. The power switch 124 operates the amplifier 128 when the TV mode is performed. When the power switch 124 is operated, the current stored in the battery 123 operates the amplifier 128 to amplify the signal input from the antenna 110. The bypass filter 125 removes the ripple current from the DC current of the battery 123 output by the operation of the power switch 124 and passes the ripple current. Here, the RC side of the power stage, that is, the bypass filter 125 and the resistor are implemented to stabilize power of the power stage of the amplifier 128 irrespective of the antenna signal, and thus have no effect on the signal received from the antenna 110. The received signal has no change in time domain or frequency domain due to RC time constant.
제1 커플링(coupling)126은 상기 안테나110을 통해 입력된 신호에서 DC전류를 제거한 신호만을 평활 회로(smoothing circuit)127로 패스시킨다. 평활 회로(smoothing circuit)127은 상기 제1 커플링(coupling)126을 통해 DC전류가 제거된 신호에서 입력신호의 리플(ripple)전류를 제거한 후 증폭기128로 패스한다. 증폭기128은 상기 파워스위치124 작동 시 상기 평활 회로(smoothing circuit)127을 통해 리플(ripple)전류를 제거한 신호를 증대하여 밴드패스 필터129로 패스시킨다.The first coupling 126 passes only the signal from which the DC current is removed from the signal input through the antenna 110 to the smoothing circuit 127. The smoothing circuit 127 removes the ripple current of the input signal from the signal from which the DC current is removed through the first coupling 126 and passes to the amplifier 128. The amplifier 128 amplifies a signal from which ripple current is removed through the smoothing circuit 127 during the operation of the power switch 124 and passes the signal to the bandpass filter 129.
밴드패스 필터129는 상기 증폭기128을 통해 입력된 신호 중 TV 대역신호만을패스시킨다. 상기 밴드패스 필터129가 패스시키는 TV대역 신호는 55~990MHz 이다. 제2 커플링(coupling)140은 상기 밴드패스 필터129를 통해 패스된 TV대역 신호에서 DC전류를 제거한 신호만을 이어폰140으로 출력시킨다.The band pass filter 129 passes only the TV band signal among the signals input through the amplifier 128. The TV band signal that the band pass filter 129 passes is 55 ~ 990MHz. The second coupling 140 outputs only the signal from which the DC current is removed from the TV band signal passed through the band pass filter 129 to the earphone 140.
상기 도 1, 도 2, 및 도 3을 참조하여 TV휴대폰용 전화기의 목걸이 안테나의 동작을 살펴보면, 먼저 목걸이 안테나의 상기 충전부120에 설치된 상기 태양전지121을 통해 태양광에너지는 전기에너지로 변환된다. 상기 태양전지121을 통해 변환된 전류는 배터리123에 저장된다. TV휴대용 전화기의 사용자가 TV 모드를 수행하기 위해 상기 파워스위치124를 작동하면, 상기 배터리123에 저장된 전류는 상기 증폭기128을 동작시킨다. 이때, 상기 배터리123에서 출력되어 상기 증폭기128을 동작시키는 DC전류는 바이패스 필터125를 통해 상기 DC전류에 섞인 리플(ripple)전류가 제거된다.Referring to FIGS. 1, 2, and 3, the operation of the necklace antenna of the TV mobile phone is described. First, solar energy is converted into electrical energy through the solar cell 121 installed in the charging unit 120 of the necklace antenna. The current converted by the solar cell 121 is stored in the battery 123. When the user of the TV portable telephone operates the power switch 124 to perform the TV mode, the current stored in the battery 123 operates the amplifier 128. At this time, the DC current output from the battery 123 to operate the amplifier 128 is removed through the bypass filter 125 ripple (ripple) mixed with the DC current.
상기 배터리123에서 출력된 전류로 동작된 상기 증폭기128은 신호를 증폭한다. 이때 상기 증폭기128에서 증폭되는 신호는 안테나110을 통해 입력되어 상기 제1 커플링(coupling)에서 DC전류를 제거한 신호이다. 또한 상기 신호는 평활 회로(smoothing circuit)를 통해 상기 신호에 포함된 리플(ripple)전류가 제거된다.The amplifier 128 operated by the current output from the battery 123 amplifies a signal. In this case, the signal amplified by the amplifier 128 is input through the antenna 110 to remove the DC current from the first coupling (coupling). In addition, the ripple current included in the signal is removed through a smoothing circuit.
상기 증폭기128을 통해 증폭된 신호는 다시 밴드패스 필터129를 통해 특정 주파수를 제거하고 TV대역신호(55~990MHz)만을 증폭시켜 이어폰140으로 출력된다.The signal amplified by the amplifier 128 is again removed through a band pass filter 129 and amplified only the TV band signal (55 ~ 990MHz) is output to the earphone 140.
즉, 상술한 바와 같이 본 발명은 TV휴대폰용 전화기의 목걸이 안테나에 태양전지를 이용한 충전장치를 설치함으로써, 저가로 간편하게 전원을 공급할 수 있는 TV휴대폰용 전화기를 제공할 수 있는 효과가 있다.That is, as described above, the present invention provides an TV phone phone that can be easily supplied at low cost by installing a charging device using a solar cell in the necklace antenna of the TV phone.
