본 고안은 자동차의 제동등 점등회로에 관한 것으로서 뒤따르는 자동차의 운전자에게 제동상태를 정확히 전달하고 경각심을 일깨워 주므로서 교통사고를 미연에 방지토록함을 목적으로 한 것이다.The present invention relates to a braking lamp lighting circuit of a vehicle, which aims to prevent a traffic accident in advance by accurately transmitting a braking state to a driver of a following vehicle and arousing awareness.

자동차의 종류가 다양해짐에 따라 제동등의 부착 위치와 모양, 제동등의 밝기가 다양하여 주행중 불시에 점등되는 제동등을 운전자가 용이하게 인지하기가 사실상 곤란할뿐 아니라 제동등의 조도가 떨어지거나 제동등에 빛이 반사되는 경우 제동등이 점등된 상태인지 빛의 반사에 의한 것인지의 식별이 곤란하고 특히 제동등이 점등되는 그 순간을 보지 못한 경우에는 제동등이 점등된 것인지 또는 차폭등이 점등된 것인지 식별이 곤란하여 위험상태를 인지하여 못하는 등의 문제점이 있었다.As the types of automobiles are diversified, the location and shape of the brake lights and the brightness of the brake lights vary, making it difficult for the driver to easily recognize the brake lights that turn on unexpectedly while driving. It is difficult to identify whether the brake light is on or reflection of light, and especially if you do not see the moment when the brake light is turned on, it is difficult to identify whether the brake light is on or the vehicle is on. There was a problem such as not recognized.

본 고안은 이러한 문제점을 해결하기 위한 방법으로 제동등을 연속 점멸 점등토록 하여 뒤따르는 자동차의 운전자에게 제동상태를 확실히 전달하는 방법이 있으나 이는 교차로에서 신호를 대기하는 경우에는 뒷자동차의 운전자에게 시력장애 및 피로감을 가중 시키게 되며 제동등을 뒷유리창에 별도로 추가 부착하여 제동상태를 확실히 전달토록 하는 예도 있으나 이 또한 뒷 유리창에 반사되므로 운전자 자신에게 장애를 야기시키는 등의 단점이 있었다.In order to solve this problem, the present invention has a method of reliably transmitting the braking state to the driver of the following vehicle by turning on the brake light continuously and continuously. There is an example to increase the feeling of fatigue and to attach the braking light to the rear window separately to ensure the braking state, but this also reflects the rear window, causing the driver to cause a disability.

이러한 단점을 시정키 위하여 브레이크가 작동되면 제동등이 일정시간(수초이내)동안 수회 점멸한후 통상의 제동등과 같이 연속 점등토록 안출한 것으로서 첨부된 도면에 의하여 상세히 설명하면 다음과 같다.When the brake is operated to correct these disadvantages, the braking light flashes several times for a predetermined time (within a few seconds) and then lights up continuously such as a normal braking light.

UJT에 가변저항(VR), 콘덴서(C2) 및 저항(R1,R2)을 접속하여 통상의 펄스발생부(A)를 구성하고 그 출력은 다이오드(D1)를 통하여 플립플롭회로(F1∼F4)로 구성된 집적회로(IC)에 인가하되 플립플롭회로(F1∼F4)는 종속접속하고 플립플롭회로(F1)의 출력단자는 다이오드(D2)를 통하여 플립플롭회로(F1) 입력단자와 접속하여 플립플롭회로(F1)의 출력을 피드백하는 한편 플립플롭회로(F1)의 출력단자와 드라이브용 트랜지스터(Q1)의 베이스단자를 접속하고 트랜지스터(Q1)의 이미터단자는 접지하고, 콜렉터단자는 저항(R3)을 통하여 브레이크스위치(SW)가 ON되면전원이 인가되게 접속함과 동시에 트랜지스터(Q2)이 베이스단자와 접속 하였다.The variable resistor VR, the capacitor C 2 , and the resistors R 1 and R 2 are connected to the UJT to form a normal pulse generator A, and the output thereof is flip-flop circuits through the diode D 1 . Is applied to an integrated circuit (IC) consisting of F 1 to F 4 , but the flip-flop circuits (F 1 to F 4 ) are cascaded and the output terminal of the flip-flop circuit (F 1 ) is connected to the flip-flop circuit through a diode (D 2 ). (F 1) connected to the base terminal of the input terminal and connected to a flip-flop circuit while feeding back the output of the (F 1) the flip-flop circuit (F 1) output terminal and the driver transistor (Q 1) for a and a transistor (Q 1 When the emitter terminal of) is grounded and the collector terminal is turned on via the resistor (R 3 ), Transistor Q 2 was connected to the base terminal at the same time that power was applied.

트랜지스터(Q2)의 콜렉터단자는전원이 인가되게 접속하고 이미터단자는 제동등(L)을 접속하여 접지하였으며 미설명 부호(C1)은 콘덴서이다.The collector terminal of transistor Q 2 The power supply is connected and the emitter terminal is grounded by connecting the brake lamp (L), and the notation code (C 1 ) is the capacitor.

이와 같이 구성된 본 고안의 작용효과는 다음과 같다.Effects of the present invention configured as described above are as follows.

자동차를 정지 시키기 위해 브레이크를 작동시키면 브레이크스위치(SW)가 ON되어전원이 인가되고 가변저항(VR)을 통하여 콘덴서(C2)는 충전이 시작되나 일정전압이 충전되기전까지는 UJT는 동작하지 않는 상태이고 펄스는 발생하지 않으며 집적회로(IC)에는 펄스가 인가되지 않는다.When the brake is operated to stop the car, the brake switch (SW) is turned on Power is applied and capacitor C 2 is charged through variable resistor VR, but UJT is not operated and pulse does not occur until constant voltage is charged and pulse is not applied to integrated circuit (IC). Do not.

따라서 플립플롭회로(F1)의 출력은 "L"상태이므로 트랜지스터(Q1)는 OFF상태이나 트랜지스터(Q2)의 베이스단자에는 저항(R3)을 통하여전원이 인가되어 있으므로 트랜지스터(Q2)는 ON상태이고 따라서 제동등(L)은 점등된다.Accordingly, since the output of the flip-flop circuit F 1 is in the "L" state, the transistor Q 1 is in the OFF state, but the resistor R 3 is applied to the base terminal of the transistor Q 2 . Since the power is applied, the transistor Q 2 is in the ON state, and thus the braking lamp L is turned on.

한편 콘덴서(C2)에는 충전이 계속되어 충전전압이 일정전압 이상이 되면 UJT는 동작되고 콘덴서(C2)의 충전전압은 방전되며 저항(R2) 양단에는 일정전압의 펄스가 발생되고 다아오드(D1)를 통하여 플립플롭회로(F1)에 인가되므로 플립플롭회로(F1)의 출력은 "H" 상태가 된다.On the other hand, when charging is continued in the capacitor C 2 and the charging voltage is higher than a certain voltage, the UJT is operated, the charging voltage of the capacitor C 2 is discharged, and a pulse of a constant voltage is generated across the resistor R 2 . Since it is applied to the flip-flop circuit F 1 through (D 1 ), the output of the flip-flop circuit F 1 is in the "H" state.

따라서 트랜지스터(Q)는 ON상태가 되고 트랜지스터(Q1)의 콜렉터단자와 접속된 트랜지스터(Q2)의 베이스단자의 전위가 낮아지게 되므로 트랜지스터(Q2)는 OFF되고 제동등(L)은 소동된다.Accordingly, since the transistor Q is turned on and the potential of the base terminal of the transistor Q 2 connected to the collector terminal of the transistor Q 1 is lowered, the transistor Q 2 is turned off and the brake lamp L is turned off. .

즉 브레이크스위치(SW)가 ON되는 순간 제동등(L)은 점등되나 일정시간후 펄스가 발생되면 제동등(L)은 소동되는 것이다.In other words, when the brake switch SW is turned on, the brake light L is turned on, but when a pulse is generated after a predetermined time, the brake light L is turned off.

한편 콘덴서(C2)은 다시 충전되어 일정 전압이상이 되면 다시 UJT가 동작되고 이러한 과정이 반복되어 펄스발생부(A)는 "제2(a)도"의 펄스가 지속적으로 발생하게 되고 플립플롭회로(F1)의 출력은 "H" "L"상태가 반복되어 제동등(L)은 "제2(f)도"와 같이 "ON""OFF"상태가 반복되므로 점멸하게 된다.On the other hand, when the capacitor C 2 is charged again and is above a certain voltage, the UJT is operated again. This process is repeated, and the pulse generator A continuously generates a pulse of "second (a)" and flip-flops. The output of the circuit F 1 is repeated because the "H" and "L" states are repeated, and the brake lamp L blinks because the "ON" and "OFF" states are repeated as in the "second (f) degree".

"제2(b)도∼제2(e)도"는 플립플롭회로(F1∼F4)의 출력파형이다."Article 2 (b) degrees to claim 2 (e) Figure" is the output waveform of the flip-flop circuit (F 1 ~F 4).

일정시간이후 t1시점이 되면 플립플롭회로(F4)의 출력은 "H"상태가 되고 다이오드(D2)를 통하여 피드백되어 플립플롭회로(F1)에 입력되면 플립플롭회로(F1)의 출력은 계속 "H" 상태가 되므로 트랜지스터 (Q1)는 계속 OFF되어 있고 트랜지스터(Q2)는 ON상태가 지속되므로 제동등(L)은 계속 점등된다.When after a period of time t 1 point, the output of the flip-flop circuit (F 4) is fed back via the "H" state and the diode (D 2) is input to the flip-flop circuit (F 1) the flip-flop circuit (F 1) Since the output of the " H " is kept in the " H " state, the transistor Q 1 is kept OFF and the transistor Q 2 is in the ON state, so the brake lamp L is continuously lit.

즉 제동등(L)은 t1시간까지 수회 점멸하고 t1시간 이후에는 브레이크스위치(SW)가 OFF되지 않는한 계속 점등되는 것이다.In other words, that the brake light (L) flashes several times t to 1 hour, and was continued t the lighting after the first time, that is not a brake switch (SW) OFF.

가변저항(VR)은 펄스의 발생주기를 제어 하므로서 제동등 (L)의 점멸주기를 조정하기 위한 것이며 콘덴서(C1)는 펄스발생부(A)의 전압을 일정하게 유지하므로서 발진상태를 안정시키는 작용을 하게 되고 다이오드(D1, D2)는 역류방지용이다.The variable resistor VR controls the flashing period of the braking lamp L by controlling the generation period of the pulse. The capacitor C 1 functions to stabilize the oscillation state by keeping the voltage of the pulse generator A constant. The diodes (D 1 , D 2 ) are for backflow prevention.

이상과 같은 작용에 의하여 뒤따르는 자동차의 운전자에게 시력장애가 피로감을 가중시키는 일이 없이 제동상태를 확실히 전달하게 되므로서 교통 사고를 방지할 수 있게 되는 것이다.As a result of the above operation, the driver of the vehicle following the blindness can be surely transmitted without causing fatigue, thereby preventing traffic accidents.

본 고안에서 플립플롭회로를 4개 사용하였으나 플립플롭회로의 수를 증가 시키거나 감소시켜 그 최종출력단자에 다이오드(D2)의 애노드단자를 접속하므로서 제동등의 점멸회수를 임의로 조정할 수 있으며 펄스발생부(A)는 트랜지스터로 구성된 통상의 플립플롭회로를 사용하거나 발진전용의 집적회로 또는 GATE회로용 집적회로로된 펄스발생회로를 사용하여도 작용효과는 동일하다.In the present design, four flip-flop circuits are used, but by increasing or decreasing the number of flip-flop circuits, the number of flickers, such as braking, can be arbitrarily adjusted by connecting the anode terminal of the diode (D 2 ) to the final output terminal. (A) has the same effect even when using a conventional flip-flop circuit composed of transistors or a pulse generating circuit composed of an integrated circuit for oscillation or an integrated circuit for a GATE circuit.
