첨부도면은 본 고안의 회로도.The accompanying drawings are circuit diagrams of the present invention.

본 고안은 도로등의 임의장소에 공사중임을 표시하고자 하는 공사표시용 교번점멸기에 관한 것이다.The present invention relates to an alternating flasher for a construction marking to indicate that it is under construction at any place, such as a road.

종래 교번점멸기는 발진장치를 사이리스터 또는 트랜지스터, 저항-콘덴서 결합회로를 채용하고 있어서 램프의 점멸 튜티비의 조정이 어려웠고, 따라서, 용량변화, 온도변화에 따른 점멸시간이 최초 상태와는 다르게 변화하는등 문제점이 지적되어 오고 있다.In the conventional alternating flasher, the oscillator adopts a thyristor, a transistor, and a resistor-capacitor coupling circuit, so it is difficult to adjust the flickering tube ratio of the lamp. Problems have been pointed out.

본 고안은 상기와 같은 결함을 해소하기 위하여, 타이머회로 출력단에 D플립플롭회로를 연결하여 정확하고도 일정한 펄스신호를 출력토록 하므로서 램프의 점멸을 교번적으로 행할 수 있도록한 것이다.The present invention is to solve the above defect, by connecting the D flip-flop circuit to the output terminal of the timer circuit to output a precise and constant pulse signal to alternately flash the lamp.

이를 첨부도면에 의하여 상세히 설명하면 다음과 같다.When described in detail by the accompanying drawings as follows.

즉, 타이머회로부(1)의 출력단에 D플립플롭회로(FF1)를 연결하고, D플립플롭회로(FF1)의 출력(Q)에 제1트랜지스터(TR1)의 베이스를 연결함과 동시, 이의 콜렉터측에 제2트랜지스터(TR2)의 베이스를 연결한 다음, 제1 및 제2트랜지스터(TR1), (TR2)각각의 콜렉터에 포토커플러(PC1)(PC2)를 접속하여 제1 및 제2램프 구동회로 (A)(B)를 연결하여서 된것으로, 상기 타이머회로(IC1)는 가변저항(VR1)과 저항(R1) (R2) 콘덴서(C1)(C2) 및 타이머IC(IC1)으로 구성되어 있으며, 타이머IC(IC1)는 555타이머 IC이다. 그리고, 제1램프 구동회로(a)는 램프(L1)를 구동키 위한 것으로, 포토커플러(PC1)의 트랜지스터 콜렉터에 SCR(SCR1)의 게이트에 제어트랜지스터(TR3)를 접속하고, 브릿지 정류회로(BD1)의 a점에 트라이액(T1)의 게이트를 연결시킨 것이다. 제1램프 구동회로(a)내의 R3~R8은 저항, C3는 콘덴서 D1~D4는 브릿지정류회로(D1)내의 정류다이오드이다.That is, the D flip-flop circuit FF 1 is connected to the output terminal of the timer circuit unit 1, and the base of the first transistor TR 1 is connected to the output Q of the D flip-flop circuit FF 1 . , connecting the base of the second transistor (TR 2) in its collector side, and then, the first and second transistors (TR 1), (TR 2 ) connected to a photo coupler (PC 1) (PC 2) to each of the collector By connecting the first and second lamp driving circuits (A) and (B), the timer circuit IC 1 includes a variable resistor VR 1 and a resistor R 1 (R 2 ) and a capacitor C 1 . (C 2 ) and a timer IC (IC 1 ), and the timer IC (IC 1 ) is a 555 timer IC. The first lamp driving circuit a is for driving the lamp L 1 , and the control transistor TR 3 is connected to the transistor of the photocoupler PC 1 to the gate of the SCR 1 . The gate of the triac T 1 is connected to the point a of the bridge rectifier circuit BD 1 . The R 3 ~ R 8 in a first lamp driver circuit (a) is resistance, C 3 is a rectifier diode in the capacitor D 1 ~ D 4 is a bridge rectifier circuit (D 1).

또한 제2램프 구동회로(B)는 상기 제1램프 구동회로(A)와 동일한 것으로, 램프(L2)를 구동키 위한 것으로, 포토커플러(PC2)의 트랜지스터 콜렉터에 SCR (SCR2)의 게이트에 제어 트랜지스터(TR3)를 접속하고, 브릿지 정류회로(BD2)의 a점에 트라이액(T2)의 게이트를 연결시킨 것이다. 제2램프 구동회로(B)내의 R9~R14는 저항 C4는 콘덴서, D5~D6는 브릿지 정류회로(BD2)내의 정류다이오드이다. 그리고 도면중 R15, R16, R17, R18, R19는 저항이다.In addition to the second lamp driver circuit (B) is of the SCR (SCR 2) to the transistor collectors of to be the same as (A) with the first lamp driver circuit, as for the light (L 2) driving key, photo coupler (PC 2) The control transistor TR 3 is connected to the gate, and the gate of the triac T 2 is connected to the point a of the bridge rectifying circuit BD 2 . R 9 to R 14 in the second lamp driving circuit B are capacitors C 4 and capacitors D 5 to D 6 are rectifier diodes in the bridge rectifier circuit BD 2 . In the drawings, R 15 , R 16 , R 17 , R 18 , and R 19 are resistors.

이상과 같이 구성된 본 고안이 작용효과는 다음과 같다.The effect of the present invention configured as described above is as follows.

VCC전압이 타이머회로부(1)에 인가되면, 가변저항(VR1) 저항(R1), (R2)를 거쳐 콘덴서(C1)에 충전되어지게 되는데, 이때 듀티(duty)비로 결정되며, 발진주파수 f =로 결정되어지도록 되어 있기 때문에 사용자가 가변저항(VR1)을 조정하여 주파수 및 듀티비를 조정한다.When the VCC voltage is applied to the timer circuit unit 1, the capacitor C 1 is charged through the variable resistors VR 1 , R 1 and R 2 , where the duty ratio Oscillation frequency f = Because it is determined to be, the user adjusts the frequency and duty ratio by adjusting the variable resistor (VR 1 ).

따라서, 콘덴서(C1)에 충전된 다음 일정시간후 저항(R2)를 거쳐 충전압이 타이머IC(IC1)의 디스챠지(Discharge)단자측으로 방전되는 동작을 연속적으로 행하게 된다. 이와같이 콘덴서(C1)의 충방전 동작에 따른 타이머IC(IC1)의 출력은 일정한 구형파가 출력되게 된다. 이 출력파형은 D플립플롭(FF1)의 클럭단자(C)에 입력되어져 ½분주되면서 출력되어진다 () .Therefore, after the capacitor C 1 is charged, the charging pressure is discharged to the discharge terminal side of the timer IC IC 1 continuously through the resistor R 2 after a predetermined time. As described above, the output of the timer IC IC 1 according to the charge / discharge operation of the capacitor C 1 outputs a constant square wave. This output waveform is input to the clock terminal C of the D flip-flop (FF 1 ) and is output while being divided ½ ( .

만일, D플립플롭(FF1)의 출력(Q)에 High(이하“H”라함)신호가 출력되면 이 신호는 저항(R15)을 거쳐 트랜지스터(TR1)의 베이스에 순방향 바이어스를 걸어주게되고, 따라서, VCC전압이 저항(R17)을 거쳐 포토커플러(PC1)의 다이오드를 통해 트랜지스터(TR1)의 에미터-어스측으로 바이패스 되어져 포토커플러(PC1)가동작한다. 즉 AC전원은 브릿지정류회로(BD1)의 다이오드(D1)를 거쳐 저항(R4)(R3)및 포토커플러 (PC1)의 트랜지스터를 거치게 되고 제어 트랜지스터(TR3)는 부도통상태가 됨과 동시 저항 (R5)을 거친 전류가SCR(SCR1)의 게이트에 인가되므로 SCR(SCR1)이 도통되어 브릿지정류회로(BD1)의 다이오드(D4) 양단에 전압이 나타나게 된다. 따라서 트라이액 (T1)이 도통되므로 램프(L1)은 점등되어진다.If the high (hereinafter referred to as "H") signal is output to the output Q of the D flip-flop FF1, the signal is biased forward through the resistor R 15 to the base of the transistor TR 1 . and therefore, the voltage VCC is the resistance (R 17) via the emitter of the transistor (TR 1) through the diode of the photo coupler (PC 1) - been bypassed toward the Earth photo coupler (PC 1) and the movable small. That is, the AC power source passes through the diode (D 1 ) of the bridge rectifier circuit (BD 1 ) and the transistors of the resistor (R 4 ) (R 3 ) and the photocoupler (PC 1 ), and the control transistor (TR 3 ) is in a non-conducting state. It is soon as the simultaneous resistance (R 5) to a rough current SCR so applied to the gate of (SCR 1) will appear the voltage across the diode (D 4) of the two SCR (SCR 1) conductive bridge rectifier circuit (BD 1). Therefore, the triac T 1 is turned on, so the lamp L 1 is turned on.

이후 D플립플롭(FF)의 출력(Q)에 LOW(“L”신호라함) 신호가 출력되면 트랜지스터(TR1)의 콜렉터측에 “H”신호가 나타나 트랜지스터(TR2)가 도통됨과 동시, 포토커플러(PC1)은 부동작, 포토커플러(PC2)는 동작을 하게된다. 따라서, 제1램프 구동회로(A)내의 트랜지스터(TR3)의 베이스에는 저항(R7)을 거친 신호가 인가되므로 트랜지스터(TR3)은 도통되어 SCR(SCR1)은 차단되고, 램프(L1)은 꺼지게 된다. 상기에 있어서, 포토커플러(PC2)가 동작되므로, AC전원은 브릿지 정류회로(BD2)의 다이오드 (D5)를 거쳐 저항(R11)-SCR(SCR2)의 게이트에 인가되므로 SCR(SCR2)가 도통되어 브릿지 정류회로(BD2)의 다이오드(D8)양단에 전압이 나타나 트라이액(T2)가 동작되고, 따라서 램프(L2)가 점등되어진다. 이후 D플립플롭(FF1)의 출력(Q)에 “H”신호가 출력되면 램프(L2)는 꺼지고 램프(L1)은 점등되어지며, 이들의 시간은 상기한 바와같이 타이머회로부(1)에서의 가변저항(VR1)으로 조정시킨다.After that, when the LOW ("L" signal) signal is output to the output Q of the D flip-flop FF, the "H" signal appears on the collector side of the transistor TR 1 , and at the same time as the transistor TR 2 becomes conductive, The photo coupler PC 1 is inoperative and the photo coupler PC 2 is operated. Thus, the first because the signal base is subjected to the resistance (R 7) of the transistor (TR 3) in a lamp driver circuit (A) applied to the transistor (TR 3) is conducting SCR (SCR 1) is cut off, the lamp (L 1 ) is turned off. In the above, since the photocoupler PC 2 is operated, the AC power is applied to the gate of the resistor R 11 -SCR (SCR 2 ) through the diode D 5 of the bridge rectifying circuit BD 2 , so that the SCR ( SCR 2 ) is turned on so that a voltage appears across the diode D 8 of the bridge rectifier circuit BD 2 to operate the triac T 2 , and thus the lamp L 2 is turned on. After that, when the “H” signal is output to the output Q of the D flip-flop FF 1 , the lamp L 2 is turned off and the lamp L 1 is turned on, and the time is the timer circuit unit 1 as described above. Adjust with the variable resistance (VR 1 ) at).

이상과같이, 타이머회로부(1)의 발진주파수가 듀티비에 의한 출력파형을 D플립플롭(FF1)에 의해 ½분주시켜 안정되게 출력되는 파형을 이용하여 공지한 제1, 제2램프 구동회로(A)(B)를 교번적으로 점멸케하므로서, 종래의 용량변화, 온도변화에 따른 점멸시간등의 오동작을 배제시킬 수 있게 되는 유용하고도 실용적인 고안이다.As described above, the first and second lamp driving circuits are known using a waveform in which the oscillation frequency of the timer circuit unit 1 divides the output waveform due to the duty ratio ½ by the D flip-flop FF 1 and stably outputs the waveform. By alternately flashing (A) and (B), it is a useful and practical design that can eliminate the malfunctions such as the flashing time according to the conventional capacity change and temperature change.
