The constant voltage circuit part D of the circuit part B is comprised by the fluorescent lamp drive circuit part C which receives the stabilized power supply and signal of the human-contact detection part A, and turns on a fluorescent lamp by a self-contained operation.

인체 접촉 감지부(A)는 저항 (R1)-(R4)과 텃치 스위치(1)과 직렬 접속된 저항(R4)에 연결된 낸드게이트(2)(3)와 이 낸드게이트(3)의 출력단에 클럭단자를 연결한 플립플롭(FF1)으로 구성한다.The human body contact detecting unit (A) includes the NAND gates (2) (3) and the NAND gates (3) connected to the resistors (R 4 ) connected in series with the resistors (R 1 )-(R 4 ) and the quench switch (1). It consists of a flip-flop (FF 1 ) connecting the clock terminal to the output terminal of.

신호음 발생 회로부(B)는 낸드게이트(3)의 출력단에 클럭단자를 연결한 플립플롭(FF2)과, 이 플립플롭(FF2)의 출력단에 연결한 발진회로부(6)와, 낸드게이트(4)의 출력단에 연결한 부저(7)로 구성한다.The beep generator circuit portion B includes a flip-flop FF 2 having a clock terminal connected to the output terminal of the NAND gate 3, an oscillation circuit portion 6 connected to the output terminal of the flip-flop FF 2 , and a NAND gate ( It consists of a buzzer (7) connected to the output terminal of 4).

상기 플립플롭(FF2)의 출력단에 연결한 발진회로부(6)는 낸드게이트(4)(5)와 저항(R5)(R6)및 콘덴서(C1)로 구성되어 있다.The oscillation circuit part 6 connected to the output terminal of the flip-flop FF 2 includes a NAND gate 4, 5, a resistor R 5 , R 6 , and a capacitor C 1 .

형광등 구동회로부(C)는 자려식 충방전회로를 채택한 것으로, 트랜지스터(8)(9)의 발진을 위한 인덕터(10)(11) 및 콘덴서(12)(13)와, 상기 트랜지스터(8)(9)의 콜렉터에 각각 연결한 스위칭 전계효과 트랜지스터(14)(15)와, 형광등(16)의 점등개시 및 유지를 위한 콘덴서(C2)(C3)및 인덕터(17)로 구성한다.The fluorescent lamp driving circuit unit C adopts a self-contained charging and discharging circuit, and includes an inductor 10, 11, a capacitor 12, 13 for oscillation of the transistors 8, 9, and the transistor 8 ( A switching field effect transistor 14 (15) connected to the collector of 9), and a capacitor C 2 (C 3 ) and an inductor 17 for starting and maintaining the lighting of the fluorescent lamp 16, respectively.

또한, 통상의 정전압회로부(D)는 트랜스(17), 브릿지 다이오드(18), 정전 압집적회로(19) 및 트라이액(20)으로 구성되어 있다.In addition, the normal constant voltage circuit section D is composed of a transformer 17, a bridge diode 18, an electrostatic integrated circuit 19, and a triac 20.

상기 정전압회로부(D)는 형광등 구동회로부(C)에 안정화된 전원을 공급하며, 정전압 IC(IC)에 의해 정전압 된 전원을 각 회로부의 집적회로에 안정적으로 공급하게 된다.The constant voltage circuit unit D supplies the stabilized power to the fluorescent lamp driving circuit unit C, and stably supplies the power regulated by the constant voltage IC IC to the integrated circuit of each circuit unit.

도면중 미설명부호 21은 형광등 구동 회로부(C)의 다이악이고, 22는 형광등 구동표시부이다.In the figure, reference numeral 21 denotes a diak of the fluorescent lamp driving circuit unit C, and 22 is a fluorescent lamp driving display unit.

이와 같이 구성된 본 고안은, 텃치 스위치(1)을 시키면 인체 접촉 감지부(A)의 저항(R1)-(R4)에는 미세전류가 흐르게 되고, 이 저항(R1)-(R4)을 통하여 흐르는 전류에 의해 낸드게이트(2)에 높은 레벨의 신호가 입력된다.The present design constructed as is, when the teotchi switch (1) resistance (R 1) of the human body contact sensing unit (A) - and has to flow a micro-current (R 4), the resistance (R 1) - (R 4) A high level signal is input to the NAND gate 2 by the current flowing through the NAND gate.

낸드케이트(2)에 입력되는 높은 레벨의 신호가 낮은 레벨의 신호로 출력되어 낸드게이트(3)에 입력되므로, 이 낸드게이트(3)의 출력단에는 높은 레벨의 신호가 출력되어 플립플롭(FF1)(FF2)으로 각각 입력된다.Since a high level signal input to the NAND gate 2 is output as a low level signal and input to the NAND gate 3, a high level signal is output to the output terminal of the NAND gate 3 to flip-flop FF 1. (FF 2 ), respectively.

즉, 낸드게이트(2)(3)를 거치면서 파형정형된 신호를 플립플롭(FF2)과 발진회로부(6)에 의해 발진주파수가 발생되게 하여 부저(7)을 일정시간 동안 동작시킴으로서 형광등의 동작개시를 알린다.That is, the oscillation frequency is generated by the flip-flop FF 2 and the oscillation circuit part 6 while passing the NAND gate 2 and 3 to operate the buzzer 7 for a predetermined time. Inform the start of operation.

이때 상기 플립플롭(FF2)의 출력단에는 낮은 레벨의 신호가 출력되어 트랜지스터(9)가 비도통상태로 되고 다이악(21)은 ON상태가 되면서 전계효과 트랜지스터(15)를 도통시킨다.At this time, a low level signal is output to the output terminal of the flip-flop FF 2 so that the transistor 9 is in a non-conductive state and the diaak 21 is in an ON state to conduct the field effect transistor 15.

따라서, 정전압회로부(D)에 의해 정류된 입력 전류는 콘덴서(C2) - 형광등(16) - 인덕터(17) - 전계효과 트랜지스터(15)를 통해 형광등(16)을 점등되게 한다.Therefore, the input current rectified by the constant voltage circuit unit D causes the fluorescent lamp 16 to be turned on through the capacitor C 2 -the fluorescent lamp 16-the inductor 17-the field effect transistor 15.

상기 인덕터(17)의 유기전압에 의해 전계효과 트랜지스터(15)는 도통상태를 유지하다가 콘덴서(13)의 충전전압이 증가하면 트랜지스터(9)가 도통되고, 전계효과 트랜지스터(15)가 비도통됨과 동시에 전계효과 트랜지스터(14)가 인덕터(10)의 역전압에 의해 턴온된다.The field effect transistor 15 remains in a conductive state due to the induced voltage of the inductor 17, but when the charging voltage of the capacitor 13 increases, the transistor 9 becomes conductive, and the field effect transistor 15 is not conductive. At the same time, the field effect transistor 14 is turned on by the reverse voltage of the inductor 10.

그리고, 전계효과 트랜지스터(15)가 비도통상태에서 콘덴서(C2)의 충전전압에 의해 콘덴서(C2) - 전계효과 트랜지스터(14) - 인덕터(17) - 형광등(16)으로 방전되면서 형광등(16)의 점등상태는 계속적으로 유지되는 것이다. 이 상태에서는 인덕터(17)와 콘덴서(C3)가 공진상태를 유지하게 된다.In addition, the field effect transistor 15 is discharged to the capacitor C 2 -the field effect transistor 14-the inductor 17-the fluorescent lamp 16 by the charging voltage of the capacitor C 2 in the non-conductive state. The lighting state of 16) continues to be maintained. In this state, the inductor 17 and the capacitor C 3 maintain the resonance state.

이같이 형광등(16)이 점등상태를 유지하다가 콘덴서(12)의 충전이 완료되면 트랜지스터(8)는 도통상태가 되고 전계효과 트랜지스터(14)는 비도통상태가 되므로, 상기 트랜지스터(9)가 다시 도통상태로 되는 반복동작을 수행하게 된다.In this way, when the fluorescent lamp 16 remains on and the charging of the capacitor 12 is completed, the transistor 8 is in a conductive state, and the field effect transistor 14 is in a non-conducting state. It performs the repetitive operation to be in the state.

또한, 형광등(16)이 점등된 상태에서 텃치 스위치(1)을 텃치하면 상기 동작과 반대로 형광등(16)은 소등된다.In addition, when the quench switch 1 is quenched while the fluorescent lamp 16 is turned on, the fluorescent lamp 16 is turned off in contrast to the above operation.

본 고안에 의한 형광등 스탠드의 자려식 구동회로는, 텃치 스위치에 인체가 접촉되면 트랜지스터의 도통, 비도통 동작의 반복에 의해 형광등의 점등상태를 유지되게 한 것이므로, 회로의 구성을 단순화하여 제조원가를 절감하고, 형광등의 점등상태를 안정적으로 유지할 수 있는 효과가 기대되는 매우 유용한 고안이다.The self-driving driving circuit of the fluorescent lamp stand according to the present invention is to maintain the lighting state of the fluorescent lamp by repeating the conduction and non-conduction operation of the transistor when the human body comes into contact with the quench switch, thereby simplifying the circuit configuration and reducing the manufacturing cost. And, it is a very useful design that the effect that can maintain a stable state of the fluorescent lamp is expected.
