It is connected to two relays K2 and K3 which supply current to the upper lamp 41 and the lower lamp 42, respectively.
또, 상기 절환스위치(S3)의 수동조작시에 사용되는 상기 디머스위치(S2)는 전조등스위치(S1)의 후단에 접속되어 구성된다.The dimmer switch S2 used in the manual operation of the switching switch S3 is connected to the rear end of the headlight switch S1.
또, 상기 광감지센서(10)는 대향차량의 전조등 빛이 비추이는 자동차의 전방부에 설치하되, 본 발명이 적용된 자동차의 등화가 조사되지 않는 곳에 설치하여 자차의 빛은 감지하지 않도록 하는 것이 바람직하다.In addition, the light sensor 10 is installed on the front of the vehicle in which the headlights of the opposite vehicle is shining, it is preferable to install in a place where the equalization of the vehicle to which the present invention is applied does not detect the light of the own vehicle. Do.
또, 상기 경사로감지수단(20)은 대향차간에 서로 경사로 등판시에 상대차량의 불빛을 감지하지 못하여 전조등(40)이 계속 상향등(41)으로 조사되는 것을 방지하기 위해 설치된 것으로, 제 3 도에 도시한 바와같이, 평행하게 물이 담긴 밀폐된 수조(21)가 차의 전후방을 향하도록 차체에 부착되고, 상기 수조(21)내에 일측에 물의 부력에 의해 상승하는 뜨개(22)가 설치되고, 이 뜨개(22)의 승강작용에 의해 단속되도록 상기 뜨개(22)에 접점스위치(S4)가 결합되어, 자동차가 경사로를 등판하면 상기 접점스위치(S4)가 온상태가 되도록 구성된다.In addition, the inclined path detecting means 20 is installed to prevent the headlamp 40 from continuously being irradiated with the uplight 41 by not detecting the lights of the relative vehicles at the time of climbing the slope between the opposite cars. As shown, a closed water tank 21 containing water in parallel is attached to the vehicle body so as to face the front and rear of the car, and a float 22 is installed in one side of the water tank 21 by the buoyancy of water. The contact switch S4 is coupled to the knit 22 so as to be interrupted by the lifting and lowering action of the knit 22, so that the contact switch S4 is turned on when the vehicle climbs a slope.
또한 상기 전조등제어부(30)는 제 2 도에서 도시한 바와같이 상기 광감지센서(10) 및 상기 경사로감지수단(20)의 출력단이 낸드게이트(G1)회로의 입력단에 접속되고, 상기 낸드게이트(G1)회로의 출력단은 릴레이(K1)에 구비된 하나의 가동접점(Ka)의 일측에 접속되고, 상기 낸드게이트(G1)의 출력단에 병렬로 낫게이트(G2)를 통해 릴레이(K1)의 다른 가동접점(Kb)의 일측에 접속되고, 상기 릴레이(K)를 이루는 두 가동접점(Ka,Kb)의 타측은 상기 디머스위치(S2)의 양단에 각각 접속되고, 이 릴레이(K1)의 코일(Kc)은 두 가동접점(Ka,Kb)의 후단은 바이어스저항(R1,R2)을 통해 각각 두 트랜지스터(TR1,TR2)의 에미터측에 접속되어 이루어진다.In addition, as shown in FIG. 2, the headlight control unit 30 has an output terminal of the optical sensor 10 and the slope detecting means 20 connected to an input terminal of a NAND gate G1 circuit, and the NAND gate ( The output terminal of the G1) circuit is connected to one side of one movable contact Ka provided in the relay K1, and the other end of the relay K1 is connected to the output terminal of the NAND gate G1 in parallel to the output terminal of the NAND gate G1. It is connected to one side of the movable contact Kb, and the other sides of the two movable contacts Ka and Kb constituting the relay K are connected to both ends of the dimmer switch S2, respectively, and the coil of the relay K1. Kc is formed by connecting the rear ends of the two movable contacts Ka and Kb to the emitter side of the two transistors TR1 and TR2 through the bias resistors R1 and R2, respectively.
이와같이 구성된 본 발명은 절환스위치(S3)를 자동으로 하였을 때에는, 경사로등판을 제외한 모든 야간주행시에 마주오는 대향차량의 불빛이 감지되면 전조등(40)을 하향등(42)으로, 그리고 마주오는 차량이 없을 때는 전조등(40)을 상향등(41)으로 점등하게 된다.According to the present invention configured as described above, when the switching switch S3 is automatically performed, when the lights of the opposite vehicles are detected at all night driving except for the ramp, the headlamp 40 is turned into the downlight 42, and the oncoming vehicle is When there is no headlight 40 is turned on by the high beam (41).
예를 들어, 경사로 하강중 또는 평지주행시 대향차량의 불빛이 감지되지 않는 다면, 광감지센서(10)와 경사로감지수단(20)의 접점스위치(S4)에서 각각 로우레벨의 신호가 낸드게이트(G1)의 입력단으로 인가되고, 이 낸드게이트(G1)의 출력단에는 하이레벨의 신호가 출력되어 릴레이(K1)의 가동접점(Ka)과 바이어스저항(R1)을 통해 트랜지스터(TR1)를 터언시키면 릴레이(K2)는 작동되어 상향등(41)을 점등시키게 되며, 낫게이트(G2)를 통해 출력된 로우레벨의 신호에 의하여 트랜지스터(TR2)는 오프되어 하향등(42)은 소등하게 된다.For example, if the light of the opposite vehicle is not detected during the descent or flat driving, the low level signal is respectively applied to the NAND gate G1 at the contact switch S4 of the light sensor 10 and the slope detection means 20. Is applied to the input terminal of the NAND gate G1, and a high level signal is output to the output terminal of the NAND gate G1, and the transistor TR1 is turned on through the movable contact Ka and the bias resistor R1 of the relay K1. K2 is activated to turn on the upper lamp 41, and the transistor TR2 is turned off by the low level signal output through the knock gate G2, and the lower lamp 42 is turned off.
이와같이 상향등(41)이 점등되어 주행중에 대향차량의 불빛이 감지되면 광감지센서(10)의 출력은 하이레벨의 신호로 변동되어 낸드게이트(G1)의 입력단으로 인가되고, 이 낸드게이트(G1)의 출력단에는 로우레벨의 신호가 출력되어 바이어스저항(R1)을 통해 트랜지스터(TR1)를 턴오프시킨다. 이에 따라 릴레이(K1)는 작동하지 않게 되어 상향등(41)을 소등하게 낫고, 낫게이트(G2)를 통해 출력된 하이레벨의 신호에 의하여 트랜지스터(TR2)는 턴온되며 릴레이(K2)를 작동시켜 하향등(42)을 점등하게 된다.As such, when the high light 41 is turned on and the light of the opposite vehicle is detected while driving, the output of the light sensor 10 is changed to a high level signal and applied to the input terminal of the NAND gate G1, and the NAND gate G1 is applied. A low level signal is output to the output terminal of the transistor TR1 through the bias resistor R1. Accordingly, the relay K1 does not operate so that the upper lamp 41 is lightly turned off, and the transistor TR2 is turned on by the high level signal outputted through the sickle gate G2, and the relay K2 is operated to move downward. The lamp 42 is turned on.
이와같이 절환스위치(S3)를 자동모드로 선택하였을 때는 디머스위치(S2)의 작동에 의하지 않고 자동으로 작동되지만, 절환스위치(S3)를 수동모드로 하였을때에는 상기 릴레이(K1)의 두 가동접점(Ka,Kb)이 절환접속되므로 디머스위치(S2)의 작동에 의하여 두 트랜지스터(TR1,TR2)의 통전을 제어하므로 운전자의 임의조작에 의하여 전조등(40)의 조사각을 조작할 수 있게된다.In this way, when the switching switch (S3) is selected as the automatic mode, it is automatically operated without the operation of the dimmer switch (S2) .However, when the switching switch (S3) is set to the manual mode, the two movable contacts of the relay (K1) ( Since Ka and Kb are switched, the energization of the two transistors TR1 and TR2 is controlled by the operation of the dimmer switch S2, so that the irradiation angle of the headlamp 40 can be manipulated by the driver's arbitrary operation.
또한, 본 발명은 자동차의 경사로 등판시에 차의 전방부가 들리우게 되면 하향등만으로도 전방조사가 충분한 점에 착안하여 구성됨으로써, 절환스위치(S3)를 자동으로 세팅하면 상기 경사로감지수단(20)를 이루는 접점스위치(S4)의 입력신호에 의하여 전술한 작동과정을 거쳐 하향등(42)을 점등하게 되며 경사로를 벗어나면 상향등(41)이 점등되어 전술한 바와 같이 대향차의 전조등 빛에 의해 절환하여 점등하게 된다.In addition, the present invention is configured by paying attention to the fact that the front irradiation of the car when the front part of the car is lifted at the time of climbing the ramp of the car, and by setting the switching switch (S3) automatically by setting the switching switch (S3) Through the above-described operation process by the input signal of the contact switch (S4) to make up the down light 42 is turned on and off the ramp, the upper light 41 is turned on and switched by the headlight of the opposite car as described above It will light up.
이와같이 작동되는 본 발명은 마주오는 대향차량의 전조등 빛에 의해 하향등으로 자동절환되고 대향차량이 없는 상태에서는 상향등으로 자동절환되는 전조등의 자동절환장치를 제공하여, 디머스위치 조작에 따른 운전자의 불편을 해소하고 전조등의 부적절한 조사로 인하여 유발되는 사고를 방지함과 아울러, 언덕등판시에 감지되지 않는 상대차량의 전조등 빛을 고려하여 하향등으로 작동되도록 함으로써 상대운전자의 시야확보에 따른 불편을 배제하는 유용한 것이다.The present invention operated as described above provides an automatic switching device of the headlight which is automatically switched to the downlight by the headlight light of the opposite vehicle and automatically switched to the uplight in the absence of the opposite vehicle, the inconvenience of the driver according to the dimmer switch operation To prevent accidents caused by improper irradiation of the headlights and to operate as a downlight in consideration of the headlights of the relative vehicles that are not detected during hill climbing, thereby eliminating inconvenience caused by securing the visibility of the other driver. It is useful.
