본 고안은 광감지소자를 갖는 2중헤드램프에 관한 것으로서, 보다 상세하게는 차량을 운행하는 과정에서 헤드램프의 이상유무를 광감지소자로 헤드램프의 광을 감지하고, 헤드램프와 보조램프가 일체로 형성된 보조램프를 점등시켜 전방시야를 확보하도록 한 광감지소자를 갖는 2중헤드램프에 관한 것이다.The present invention relates to a dual headlamp having a photosensitive device, and more particularly, to detect the light of the headlamp with the photosensitive device based on whether there is an abnormality of the headlamp in the course of driving a vehicle. The present invention relates to a double head lamp having a light sensing element for lighting an auxiliary lamp formed integrally to secure a front view.
공지된 바와 같이, 주변 밝기를 감지하는 소자(Cadmiumsulfide : 이하 CDS함)로, 포토트랜지스터의 일정으로 주변의 광을 감지하여 감지된 신호에 따라 저항값이 변화되는 소자이다. 즉, 주변의 밝기에 따라 제로(0)에서 무한대(∝)로 변화되며, 주간에는 저항값이 제로(0)에 가까우며, 야간에는 저항값이 무한대(∝)에 까깝게 된다. 상기 CDS를 사용하는 회로는 전자알람으로, 주변의 밝기를 감지하여 멜로디음을 발생시키는 장치 등에 사용되며, 현재는 포토트랜지스터 또는 포토다이오드를 등으로 대치되어 많이 사용된다.As is well known, a device for detecting ambient brightness (Cadmiumsulfide: referred to as CDS) is a device in which a resistance value is changed according to a detected signal by sensing ambient light with a constant of a phototransistor. That is, it changes from zero (0) to infinity according to the brightness of the surroundings, the resistance value is close to zero during the day, and the resistance value is close to infinity at night. The circuit using the CDS is an electronic alarm, which is used in a device for generating a melody sound by sensing the brightness of the surroundings, and is currently replaced by a phototransistor or a photodiode.
일반적으로 차량에 구비된 헤드램프는 정면 범퍼에 설치되며, 범퍼의 양측에 외부의 충격에서 헤드램프를 보호하기 위해 설치된 케이스에 반사경이 구비된다. 상기 헤드램프의 하이비임(High beam:상향등)은 광원이 없는 지역에서 전방시야를 보다 넓게 확보하기 위한 램프이고, 로우비임(Low beam)은 대향차의 운전자가 현혹되지 않도록 광도를 약하게 하고 동시에 비임을 낮추게 되는 것이다.In general, the headlamp provided in the vehicle is installed in the front bumper, the reflector is provided on the case installed to protect the headlamp from external impact on both sides of the bumper. The high beam of the headlamp is a lamp for securing a wider front view in an area where there is no light source, and the low beam of the headlamp weakens the luminosity so that the driver of the opposite vehicle is not deceived. Will be lowered.
첨부도면, 도 1은 헤드램프의 구성을 도시한 회로도이다. 도 1을 살펴보면, 헤드램프(100)는 차량의 배터리전원에 의해 구동되고, 라이트스위치(SW1), 디머스위치(SW2)등으로 구성되며, 양쪽의 헤드램프(100)는 하이비임(상향등)과 로우비임(하향등) 별로 병렬로 접속되어 있다.1 is a circuit diagram showing a configuration of a head lamp. Referring to FIG. 1, the headlamp 100 is driven by the battery power of the vehicle, and is composed of a light switch SW1, a dimmer switch SW2, and the like, and both headlamps 100 are high beam (uplight). And low beams are connected in parallel.
상기 라이드스위치(SW1)는 제 1접점과 제 2접점 및 제 3접점으로 구분되어 운전자가 라이트스위치(SW1)를 제 1접점에서 제 2접점으로 변환되면, 미등이 점등된다. 또한, 제 1접점 또는 제 2접점에서 제 3접점으로 변환하게 되면, 헤드램프(100)가 점등된다. 상기 헤드램프(100)가 점등된 상태로 디머스위치(SW2)의 손잡이(Knob)를 움직여 내부의 스위치접점이 연동되도록 전원과 접속하게 된다. 따라서, 디머스위치(SW2)는 라이트의 비임을 바꾸는 스위치로, 운전자가 손으로 손잡이를 전·후로 섭동시켜 상향등 또는 하향등을 점등시키게 되는 것이다.The ride switch SW1 is divided into a first contact point, a second contact point, and a third contact point. When the driver converts the light switch SW1 from the first contact point to the second contact point, the tail light is turned on. In addition, when the first contact point or the second contact point is converted to the third contact point, the head lamp 100 is turned on. By moving the knob Knob of the dimmer switch SW2 while the head lamp 100 is turned on, the head lamp 100 is connected to a power source so that the internal switch contact is interlocked. Therefore, the dimmer switch SW2 is a switch for changing the beam of light, and the driver turns the handle up and down by hand to turn on the upward or downward light.
이와 같은 헤드램프(100)는 야간 또는 안개등으로 인하여 전방시야를 확보하지 못하게 될 때 헤드램프가 점등되어 전방시야를 확보하게 되는 것이다. 그러나, 운전자가 헤드램프(100)를 구동시키는 라이트스위치(SW1)의 조작에 따라 램프가 점등되어 전방시야를 확보하기 램프의 이상유무를 항상 정검을 실시해야 하는 불편한 문제점을 갖게 된다.Such headlamp 100 is to secure the front view when the headlamp is turned on when the front view is not secured due to night or fog. However, when the driver operates the light switch SW1 for driving the headlamp 100, the lamp is turned on, and thus, there is an inconvenience in that the lamp should always be checked for abnormality of the lamp to secure the front view.
또한, 광원이 없는 지역을 운행할 때 헤드램프가 점등되지 않은 경우 전방시야를 확보하지 못하게 되고, 대향된 차선의 차량이 상태방 차량을 인식하기 어려운 문제점을 갖게 되는 등 충돌사고를 유발하게 되는 문제점을 갖게 된다.In addition, when the headlamp is not turned on while driving in an area without a light source, a front vision cannot be secured, and a collision accident occurs such that a vehicle in the opposite lane has a problem that it is difficult to recognize a vehicle in a state room. Will have
이에 본 고안은 상기와 같은 문제점을 고려하여 안출된 것으로서, 그 목적은 차량을 운행하는 과정에서 헤드램프의 이상유무를 광감지소자로 헤드램프의 광을 감지하고, 헤드램프와 보조램프가 일체로 형성된 보조램프를 점등시켜 전방시야를 확보하도록 한 광감지소자를 갖는 2중헤드램프를 제공함에 있다.The present invention is conceived in view of the above problems, the purpose is to detect the light of the headlamp with the light sensing element in the presence or absence of the headlamp in the course of driving the vehicle, the headlamp and the auxiliary lamp integrally The present invention provides a double head lamp having a light sensing element for lighting the formed auxiliary lamp to secure a front view.
이러한 본 고안의 목적은, 배터리전원에 의해 점등되며, 전방으로 광을 조사하는 차량용 헤드램프에 있어서, 상기 각각의 헤드램프로 경유된 신호를 부정논리곱회로의 진리값으로 변환하여 헤드램프의 이상유무를 표시램프를 갖는 헤드램프유무표시부와; 상기 헤드램프가 점등된 상태로 조사되는 광을 감지하는 광감지부와; 상기 광감지센서에서 감지된 신호에 따라 배터리전원을 스위칭하는 트랜지스터에서 출력된 신호로 보조램프를 점소등시키는 보조램프구동부를 포함하여 이루어진 광감지소자를 갖는 2중헤드램프에 의해서 달성될 수 있다.The object of the present invention is a vehicle head lamp that is turned on by a battery power source, and converts a signal passed through each head lamp into a truth value of a negative logic circuit by converting the signal passed through each head lamp into an abnormality of the head lamp. A head lamp presence display unit having a presence lamp; An optical sensing unit configured to sense light emitted while the headlamp is turned on; It can be achieved by a dual head lamp having a light sensing element comprising an auxiliary lamp driver for turning on the auxiliary lamp with a signal output from the transistor for switching the battery power in accordance with the signal sensed by the light sensing sensor.

이하, 본 고안의 바람직한 실시예를 첨부된 도면에 의거하여 구체적으로 설명하면 다음과 같다.Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.
도 2은 본 고안에 따른 광감지수단을 갖는 2중헤드램프의 구성을 보인 회로도이다. 도 2을 살펴보면, 차량의 미등 및 헤드램프를 점등시키기 위한 운전자가 라이트스위치(SW1) 제 2접점으로 변환하게 되면 배터리전원에 의해 미등이 점등되고, 제 3접점으로 변환하게 되면 헤드램프가 구동되며, 상기 헤드램프를 점등시키는 전원은 헤드램프이상유무표시부(10)에 입력된다.Figure 2 is a circuit diagram showing the configuration of a double head lamp having a light sensing means according to the present invention. Referring to FIG. 2, when the driver for turning on the tail light and the head lamp of the vehicle is switched to the second switch of the light switch SW1, the tail light is turned on by the battery power, and the head lamp is driven when the driver turns to the third contact point. The power for turning on the head lamp is input to the head lamp abnormality display unit 10.
상기 헤드램프이상유무표시부(10)는 헤드램프로 경유된 신호를 부정논리곱회로(12)에 의해 각각의 헤드램프로 경유된 신호가 진리값으로 변환되고, 이 변환된 신호는 표시램프(14)에 입력된다. 즉, 부정논리곱회로(12)는 각각의 헤드램프로 경유된 신호중 로우신호가 출력되면, 부정논리곱회로(12)의 진리값에 의해 출력이 하이신호가 출력되어 표시램프(14)로 헤드램프의 이상유무를 표시하게 된다.The head lamp abnormality display unit 10 converts the signal passed through the headlamp into the truth value by the negative logic circuit 12, and the converted signal is converted into a truth value. ) Is entered. That is, when the low logic signal among the signals passed through the respective headlamps is output, the negative logic circuit 12 outputs the high signal by the truth value of the negative logic circuit 12 to output the head to the display lamp 14. It indicates the abnormality of the lamp.
또한, 헤드램프의 광을 감지하여 감지된 광으로 배터리전원을 바이패스시키는 광감지부(20)에 의해 보조램프를 구동시키는 보조램프구동부(30)의 점등을 제어하게 된다. 상기 광감지부(20)는 광을 감지하는 광감지소자로 포토트랜지스터, 포토다이오드 및 CDS 등을 이용하여 배터리전원에 의해 점소등되는 헤드램프의 광을 감지하여 배터리전원을 스위칭하도록 설치되어 있다.In addition, the lighting of the auxiliary lamp driver 30 for driving the auxiliary lamp is controlled by the light detecting unit 20 which senses the light of the head lamp and bypasses the battery power with the detected light. The light sensing unit 20 is a light sensing element that senses light and is installed to switch the battery power by sensing light of a headlamp that is turned on by a battery power using a phototransistor, a photodiode, a CDS, and the like.
상기 헤드램프가 점등되면 광감지부(20)의 광감지소자의 저항값이 최소(0)가 되어 배터리전원은 광감지부(20)로 통전된다. 상기 헤드램프가 점등되지 않으면 광감지부(20)의 광감지소자의 저항값이 최대(∝)가 되어 배터리전원은 광감지부(20)로 차단된다. 따라서, 헤드램프의 광이 감지되지 않으면, 배터리전원은 보조램프구동부(30)의 트랜지스터(32) 베이스 구동전원으로 공급된다.When the head lamp is turned on, the resistance value of the photosensitive device of the photosensitive unit 20 becomes minimum (0) so that the battery power is supplied to the photosensitive unit 20. If the head lamp is not turned on, the resistance value of the light sensing element of the light sensing unit 20 becomes the maximum and the battery power is cut off by the light sensing unit 20. Therefore, when the light of the head lamp is not detected, the battery power is supplied to the transistor 32 base driving power of the auxiliary lamp driving unit 30.
상기 트랜지스터(32)는 광감지부(20)에서 헤드램프의 광이 감지되지 않을 때 입력되는 신호에 의해 배터리전원을 스위칭하여 보조램프(34)를 점등시키게 된다.The transistor 32 turns on the auxiliary lamp 34 by switching the battery power by a signal input when the light of the head lamp is not detected by the light sensing unit 20.
첨부도면, 도 3은 2중헤드램프가 설치된 상태의 평면도이다. 도 3을 살펴보면, 광감지부(20)의 광감지소자는 헤드램프의 내부에 설치되고, 설치된 광감지소자는 보조램프(34)의 광에 의해 오동작을 방지하도록 설치되며, 상기 헤드램프가 점등가 점등되지 않으면, 부정논리곱회로(12)와 광감지부(20)로 헤드램프의 이상유무를 감지하여 감지된 신호에 의해 보조램프(34)를 점등시켜 차량의 전방시야를 확보하게 되고, 인스트루먼트 패널에 구비된 표시램프(14)가 점등되어 헤드램프의 이상유무를 운전자에게 알려주게 된다.3 is a plan view of a state in which a double head lamp is installed. Referring to FIG. 3, the light sensing element of the light sensing unit 20 is installed inside the head lamp, and the installed light sensing element is installed to prevent a malfunction by the light of the auxiliary lamp 34, and the head lamp is turned on. If it is not turned on, the negative logic circuit 12 and the light detecting unit 20 detect the abnormality of the head lamp and light the auxiliary lamp 34 by the detected signal to secure the front field of view of the vehicle. The display lamp 14 provided on the panel is turned on to inform the driver of the abnormality of the head lamp.
이와 같은 구성을 갖는 본 고안의 작용은, 야간 혹은 안개등으로 전방시야를 확보하지 못하게 될 때 운전자가 전방시야를 확보하기 위해 라이트스위치(SW1)의 제 3접점으로 변환하게 되면, 차량의 배터리전원에 의해 헤드램프가 점등된다.The action of the present invention having such a configuration is that when the driver cannot secure the front view at night or by fog lights, the driver switches to the third contact point of the light switch SW1 to secure the front view. The headlamp is turned on.
이때, 헤드램프로 경유된 배터리전원을 논리신호로 반전시키는 부정논리곱회로(12)에서 경유된 신호를 논리신호로 변환하여 변환된 신호에 의해 인스트루먼트 패널에 구비된 표시램프(14)를 점등시켜 헤드램프의 이상유무를 표시하게 된다. 즉, 헤드램프로 경유된 배터리전원의 출력된 신호중 로우감지되면, 부정논리곱회로의 진리값에 의해 하이신호로 반전되어 표시램프(14)가 점등되므로 헤드램프의 이상유무를 표시하게 된다.At this time, in the negative logic circuit 12 which inverts the battery power passed through the headlamp into a logic signal, the signal passed through is converted into a logic signal, and the display lamp 14 provided in the instrument panel is turned on by the converted signal. It indicates the abnormality of the head lamp. That is, when the low signal is detected among the output signals of the battery power source passed through the head lamp, the display lamp 14 is turned on by being inverted to a high signal by the truth value of the negative logic circuit, thereby indicating whether or not the head lamp is abnormal.
또한, 헤드램프의 광을 감지하는 광감지부(20)로 입력되는 신호로 보조램프구동부(30)의 보조램프(34)는 상기 광감지부(20)의 광감지소자로 감지하는 헤드램프의 광이 감지되지 않을 때, 광감지소자에 의해 바이패스되는 배터리전원이 트랜지스터(32)의 베이스 구동전류로 흐르게 되고, 이때, 트랜지스터(32)의 콜랙터에 연결된 배터리전원을 스위칭하게 되며, 스위칭된 전원으로 보조램프(34)를 점등시켜 차량의 전방시야를 확보하게 되는 것이다.In addition, the auxiliary lamp 34 of the auxiliary lamp driver 30 as a signal input to the light sensing unit 20 for detecting the light of the headlamp of the headlamp to sense the light sensing element of the light sensing unit 20 When light is not detected, the battery power bypassed by the photosensitive device flows into the base driving current of the transistor 32, and at this time, the battery power connected to the collector of the transistor 32 is switched and switched. The auxiliary lamp 34 is turned on by the power source to secure the front view of the vehicle.
따라서, 헤드램프로 흐르는 배터리전원에 의해 헤드램프가 점등되고, 이 점등된 광으로 광감지소자의 고유저항값이 제어된다. 즉, 헤드램프가 점등되지 않을 때, 광감지소자의 저항값이 최대(∝)가 되어 각각의 트랜지스터(32)의 베이스 저항값 보다 광감지소자의 고유저항값이 월등히 상승된 상태이므로 배터리전원이 각각의 트랜지스터(32)에 입력되고, 입력된 신호로 트랜지스터(32)를 턴온시키게 되므로 보조램프(34)를 점등시키게 된다.Therefore, the head lamp is turned on by the battery power flowing through the head lamp, and the resistivity value of the light sensing element is controlled by the lit light. That is, when the head lamp is not turned on, the resistance value of the photosensitive device becomes maximum, and the specific resistance value of the photosensitive device is much higher than the base resistance of each transistor 32. The transistor 32 is input to each transistor 32 and the transistor 32 is turned on by the input signal, thereby turning on the auxiliary lamp 34.
이상에서 살펴본 바와 같이 본 고안에 따른 광감지수단을 갖는 보조헤드램프점등장치는, 야간 또는 안개등으로 인하여 전방시야를 확보하기 위해 헤드램프가 점등되지 않는 경우, 헤드램프로 경유된 신호를 부정논리곱회로의 진리값으로 신호가 반전되어 헤드램프의 이상유무를 표시하게 되고, 헤드램프의 광을 감지하는 광감지소자로 헤드램프의 광을 감지하여 헤드램프와 보조램프가 일체로 형성된 2중헤드램프의 보조램프를 점등시켜 전방으로 광을 조사하여 전방시야를 확보되며, 인스트루먼트 패널에 구비된 표시램프를 점등시켜 운전자에게 헤드램프의 이상유무를 알리게 되는 장점을 갖는 장치인 것이다.As described above, the auxiliary headlamp lighting apparatus having the light sensing means according to the present invention, when the headlamp is not turned on to secure the front view due to the night or fog lights, the signal passed through the headlamp is negative logic The signal is inverted by the truth value of the circuit to indicate the abnormality of the head lamp, and a double head lamp in which the head lamp and the auxiliary lamp are integrally formed by detecting the light of the head lamp with an optical sensing element that senses the light of the head lamp. It is a device having an advantage that the front lamp is secured by illuminating the auxiliary lamp of the front to secure the front field of view, and the indicator lamp provided on the instrument panel is turned on to inform the driver of the abnormality of the head lamp.
