비상시 전조등 자동점멸장치Headlight flasher in case of emergency

제1도는 기지의 전조등에 관한 동작회로도.1 is an operation circuit diagram for a known headlamp.

제2도는 본 고안의 요부를 나타내는 회로도.2 is a circuit diagram showing the main part of the present invention.

제1도의 기능은 야간에 차량의 상호 교행시 상대방 차량의 전조등 밝기를 검출하여 그 밝기를 상호 흐리게 하고 상호 교행이 끝나면 다시 그 밝기를 원상태로 높혀 주는 “광전제어전조등 광촉 조정장치”회로에 제2도에 표시한 바와 같이 IC2, IC3및 IC4의 전자 구동신호 회로를 부가하여 주간에 전조등을 점등하고 주행할 필요가 있을 때(비상시)또는 야간에 제1도의 회로(특허 제9390호)를 부착하지 않는 차량과 상호 교행할 때는 본 고안 장치를 한 차량 전조등이 전자적으로 자동 점멸하게 함으로서 상대방 차량에 경고를 하며 원조등을 근조등으로 하향 조정토록 하는 경고신호로서 동작케 하여 교통사고를 방지하고 안전운행을 할 수 있게 한 장치이다.The function of FIG. 1 detects the brightness of the headlights of the other vehicle when the vehicle crosses at night, blurs the brightness of each other, and increases the brightness to the original state after the intersection of the crosses. As shown in the figure, the electronic driving signal circuits of IC 2 , IC 3, and IC 4 are added to the circuit of FIG. 1 when it is necessary to turn on the headlights during daytime (in case of emergency) or at night (patent 93.90). When crossing with a vehicle that does not have a warning light, the vehicle headlights with the device of the present invention are automatically flashed electronically to warn the other vehicle and to operate as a warning signal to lower the headlights to the headlights to prevent traffic accidents. It is a device that enables safe operation.

종래에는 주간에 비상시나 위험신호 또는 상대방 차량에 경고를 목적으로 전조등을 점등코져 할 때는 일일이 전조등 스위치를 개폐하거나 회전방향 표시등(황색)을 전후 좌우 동시에 점멸시킴으로서 비상차량임을 표시했으나 이것은 회전방향 표시등을 동시에 점멸 동작시키기 때문에 특정방향으로 회전하고져 할 경우에는 이러한 비상신호 체제에서 회전하고져 하는 회전방향 표시신호로 전환해야 함으로 비상차량체제에서 일반차량으로 바뀌어야 한다. 그러나 본 고안은 전조등의 점멸과 동일한 회로로 구성되어 있는 차량후미의 차폭등(적색)과 전면 미등도 동시 점멸함으로서 비상차량체제에서 회전방향 표시를 그대로 할 수 있다. 이러한 전자회로가 제1도의 회로에 제2도의 IC2, IC3및 IC4의 부가회로를 첨설하여 신뢰성 높은 전자 구동신호 회로를 구성한 것으로서 이를 첨부도면에 의하여 설명하면 다음과 같다.Conventionally, when the headlights are turned on for daytime emergency or danger signal or warning of the other vehicle, it is indicated that the vehicle is an emergency vehicle by opening or closing the headlight switch or flashing the rotation direction indicator (yellow) at the same time. In order to rotate in a specific direction because it blinks at the same time, it has to be changed from emergency vehicle system to general vehicle because it has to be converted to the direction of rotation signal to be rotated in such emergency signal system. However, according to the present invention, the turning direction indication can be maintained in the emergency vehicle system by simultaneously blinking the vehicle rear light (red) and the front tail light which are composed of the same circuit as the headlight. Such an electronic circuit is formed by attaching additional circuits of IC 2 , IC 3, and IC 4 of FIG. 2 to the circuit of FIG. 1 to form a highly reliable electronic driving signal circuit, which will be described with reference to the accompanying drawings.

1) 회로 구성1) Circuit composition

기지의 광전제어전조등 광촉 조정회로 장치에 광검출소자 (PH1)과 이와 직렬로 연결한 가변저항(R13)을 보조기능 회로인 IC2의 입력측에 연결하고 이의 출력신호를 받아 비교 제어하여 전조등의 밝기를 제어하는 IC3및 주간비상시 IC2의 출력을 받어 제너다이오드(ZD1)를 통한 신호와 야간비상시 저항(R15)과 가변저항(R14)으로 조정 설정된 전압(V7)과 이를 연결하고 비상눌름 스위치(SW2)의 동작에 의한 신호 및 야간에 본 고안을 부착하지 않는 차량과의 교행시에 상대방의 흐려지지 않는 불빛을 검출하여 동작되는 IC4의 출력신호에 따라 연동하는 IC3의 출력펄스에 의해서 ON·OFF 되는 트랜지스터(Q1,Q2,Q3)에 의해 차량의 전조등(R.H.L),(L.H.L)과 전면미등(FL1),(FL2) 및 후미차폭등(BL1),(BL2)이 자동 점멸되도록 구성된 것이다.Connect the photodetector device PH 1 and the variable resistor R 13 connected in series to the photoelectric control headlamp photonic control circuit device to the input side of the auxiliary function circuit IC 2 and receive the output signal to compare and control the headlight. Receives the output of IC 3 and brightness control IC 2 during daytime emergency and adjusts the signal through zener diode (ZD 1 ) and adjusts voltage (V 7 ) with resistance (R 15 ) and variable resistor (R 14 ) during nighttime emergency. And IC 3 which interlocks according to the output signal of IC 4 , which operates by detecting a signal that is not blurred by the other party when traveling with a vehicle that does not attach the present invention at night and a signal by the operation of the emergency push switch (SW 2 ). The vehicle's headlights (RHL), (LHL), front taillights (FL 1 ), (FL 2 ) and taillights (BL) are turned on and off by transistors Q 1 , Q 2 , and Q 3 , 1 ), (BL 2 ) is configured to blink automatically.

미설명부호 IC5는 정전압 IC로서 전자회로에 정전압 공급용이며 VRD1-3는 트랜지스터(Q1-3)의 충격 보호용 다이오드이고 N.L은 번호판 조명등, SW1는 전조등 스위치, R1-12는 저항, C1-7는 콘덴서이다.Unmarked IC 5 is a constant voltage IC for supplying constant voltage to electronic circuits, VRD 1-3 is a shock protection diode for transistors (Q 1-3 ), NL is a license plate lamp, SW 1 is a headlight switch, and R 1-12 is a resistor. , C 1-7 is a capacitor.

따라서 이에 대한 작용을 설명하면 다음과 같다. 주간운행중 비상시 전조등을 점등하기 위하여 전조등 스위치(SW1)를 동작시키면 제2도의 광검출소자(PH1)는 낮의 밝은 빛을 검출 내부저항이 변화하여 저항(R13)으로 조정된 전압의 값(V2)에서 더 높아진 전압(V2′)으로 변화한다.Therefore, when explaining the operation as follows. When the headlight switch SW 1 is operated to turn on the headlights during an emergency during the daytime operation, the photodetector device PH 1 of FIG. 2 detects bright light during the day, and the internal resistance is changed so that the value of the voltage adjusted by the resistor R 13 ( V 2 ) changes to a higher voltage (V 2 ′).

IC2는 O.P Amp로서 증폭이득이 1인 완충증폭기로서 동작되어 IC2의 출력단 전압(V3)는 전압(V2′)와 같아진다.IC 2 is OP Amp and operates as a buffer amplifier with a gain of 1 so that the output terminal voltage V 3 of IC 2 is equal to the voltage V 2 ′.

그러나 V2〉V3로 되면 제너다이오드(ZD1)가 도통하여 장주기타임 펄스발생 IC4의 동작으로 출력단 V5에는 장주기 펄스가 나타난다.However, when V 2 > V 3 , the zener diode (ZD 1 ) conducts and long period pulse occurs at the output terminal V 5 due to the operation of the long period pulse generator IC 4 .

이 톱니파 출력파형은 IC3의 입력에 인가되어 출력단의 V6에 그대로 나타난다.This sawtooth output waveform is applied to the input of IC 3 and appears as it is at V 6 of the output stage.

이 발진파형에 따라서 트랜지스터(Q1)이 ON·OFF되고 파워트랜지스터( Q2,Q3)가 ON·OFF되어 파워 트랜지스터(Q2,Q3) 코렉터에 각각 연결되어 있는 우측전조등(R.HL)과 좌측전조등(L.HL), 후미의 차폭등(BL1,BL2) 및 전면의 미등(FL1,FL2)이 동시에 점멸하게 되어 비상차량으로 전환되는 것이다.Transistor (Q 1) in accordance with the oscillation waveform is ON · OFF and the power transistor (Q 2, Q 3) is ON · OFF the power transistor (Q 2, Q 3) which are connected to the right headlamp Corrector (R.HL ), The left headlight (L.HL), the rear axle lights (BL 1 , BL 2 ) and the front tail lights (FL 1 , FL 2 ) will blink at the same time to convert to emergency vehicles.

그러나 필요에 의하여 후미의 차폭등(BL1,BL2)과 전면의 미등(FL1,FL2) 및 번호판 조명등(N.L)만 점등하고져 할 때는 전조등 스위치(SW1)의 1단계 동작만으로 후미의 차폭등(BL1,BL2)는 트랜지스터(Q3)의 샨드저항(R9)를 통하여, 전면의 미등(FL1,FL2)는 트랜지스터(Q2)의 샨드저항(R8)를 통하여 각각 점등되며 번호판 조명등(N.L)은 직접 접지로서 점등된다.However, when only the taillights (BL 1 , BL 2 ) and rear tail lights (FL 1 , FL 2 ) and license plate lighting lights (NL) on the rear are turned on by necessity, only one stage operation of the headlight switch (SW 1 ) is applied. Difference lamps BL 1 , BL 2 through the shank resistors R 9 of the transistor Q 3 , and taillights FL 1 , FL 2 on the front side through the resistors R 8 of the transistor Q 2 . Each lights up and the license plate lamp NL lights up as a direct ground.

야간에 운행중 비상체제 차량으로 전환하고져 할 때는 저항(R15)와 가변저항(R14)을 조정하여 설정된 분기점의 전압(V7)이 전술한 주간에 전조등을 점등했을 때의 IC2의 출력단 전압(V3)이 제너다이오드(ZD1)를 통과한 전압(V8)과 같게 설정되어 있는 회로 구성에서 눌름 스위치(SW2)를 동작시키면 주간 때와 같이 점등된 전조등(R.HL,L.HL)과 전면미등(FL1),(FL2)및 후미차폭등(BL1),(BL2)이 점멸되여 비상표시차량으로 되며 번호판 조명등(N.L)은 그대로 점등되는 것이다.The IC 2 output voltage when lit while driving emergency system resistance (R 15) and the headlight on day one the above-described voltage (V 7) of the branch point is set by adjusting the variable resistor (R 14) when hagojyeo switch to the vehicle during the night In a circuit configuration in which (V 3 ) is set equal to the voltage (V 8 ) passing through the zener diode (ZD 1 ), when the push switch (SW 2 ) is operated, the headlight (R.HL, L. HL), front tail lights FL 1 , FL 2 , and taillights BL 1 , BL 2 are flashing to become an emergency indicator vehicle, and the license plate lamp NL lights up as it is.

야간에 전조등을 점등한 상태에서 본 고안 장치를 부착한 차량과 부착하지 않은 차량의 교행시에 본 장치를 부착한 차량의 전조등은 상대방 차량의 강한 불빛이 광검출소자(PH1)에 검출되어 내부 저항의 감소로 설정전압(V2)가 변동된 전압(V2)까지 흐려지며 V2′= V3때가 흐려진 최저의 한계 밝기가 되고 V2′〉 V3로 되면 제너다이오드(ZD1)의 도통으로 전술한 주간 비상시의 동작 원리와 같이 전조등이 점멸하게 되므로 상대방 차량의 원조등을 근조등으로 바꾸도록 경고하게 되고 쌍방이 다같이 이 장치를 부착한 경우는 쌍방 전조등 불빛이 같이 흐려지므로 전조등 점멸 경고장치는 동작하지 않는다.Headlight for a vehicle attached to the unit at the time of Bishop of non-attachment and the attachment to the intended device in a state in which light the headlights at night vehicles vehicle strong light from the other vehicle is detected in the optical detection chulsoja (PH 1) Internal Resistance reduction becomes blurred to a set voltage (V 2) the variation voltage (V 2) of V 2 '= V 3 when clouded, and the limit brightness of the lowest V 2'> If a V 3 conduction of the zener diode (ZD 1) As the above-mentioned daytime emergency operation principle, the headlight flashes, so the warning light of the other vehicle is changed to the warning light, and when the two devices are attached together, the headlight flashes and the headlight flashes. The device does not work.

이상과 같이 비상체제 차량의 전조등 및 후미의 차폭등 전면의 미등을 전자적으로 점멸시켜 상대방 차량에 경고 효과를 높이고 비상 질주하면서 회전방향지시 신호를 동시에 할 수 있는 신뢰성 높은 전자 구동회로이다.As described above, it is an electronic drive circuit of high reliability that can simultaneously turn the direction signal while flashing the emergency light by flashing the tail light of the headlight of the emergency vehicle and the taillight of the rear of the vehicle.
