Description
본 고안은 헤드램프의 이상유무에 따른 보조램프구동 경고표시장치에 관한 것으로서, 보다 상세하게는 차량을 운행하는 과정에서 헤드램프의 이상유무에 따라 전류량의 변화로 배터리전원을 스위칭하여 스위칭된 배터리전원에 의해 보조헤드램프를 점등시켜 차량의 전방시야를 확보할 수 있도록 헤드램프와 보조헤드램프를 일체로 형성한 헤드램프의 이상유무에 따른 보조램프구동 경고표시장치에 관한 것이다.The present invention relates to an auxiliary lamp driving warning display device according to the abnormality of the head lamp, and more particularly, the battery power is switched by switching the battery power with a change in the amount of current in accordance with the abnormality of the head lamp during the operation of the vehicle The auxiliary lamp driving warning display device according to the presence or absence of the head lamp integrally formed with the head lamp and the auxiliary head lamp to ensure the front view of the vehicle by turning on the auxiliary head lamp.
일반적으로 헤드램프는 두 개의 필라멘트가 있으며, 하나는 먼 곳을 비추는 하이비임(High beam)의 역할을 하고, 다른 하나는 교행할 때 대향차의 운전자가 현혹되지 않도록 광도를 약하게 하고 동시에 비임을 낮추는 로우비임(Low beam)의 역할을 하게 되어 있다.In general, the headlamp has two filaments, one acting as a high beam that illuminates a distant light, and the other that weakens the brightness and lowers the beam at the same time so that the driver of the opposite vehicle is not deceived when crossing. It is supposed to act as a low beam.
상기 헤드램프는 차량의 정면 범퍼에 설치되며, 범퍼의 양측에 외부의 충격에서 헤드램프를 보호하기 위해서 설치된 케이스에 반사경이 구비된다.The headlamps are installed in the front bumper of the vehicle, and reflecting mirrors are provided on both sides of the bumper to protect the headlamps from external shocks.
첨부도면, 도 1은 일반적으로 차량에 헤드램프가 설치된 상태를 보인 사시도이고, 도 2는 일반적인 헤드램프의 구성을 도시한 회로도이다. 도 1 및 도 2를 살펴보면, 헤드램프는 차량의 배터리전원에 의해 구동되고, 라이트스위치(SW1), 디머스위치(Dimmer switch : SW2)등으로 구성되며, 양쪽의 헤드램프(3)는 하이비임(상향등)과 로우비임(하향등) 별로 병렬로 접속되어 있다.1 is a perspective view showing a state in which a head lamp is generally installed in a vehicle, and FIG. 2 is a circuit diagram showing the configuration of a general head lamp. 1 and 2, the headlamp is driven by the battery power of the vehicle, and is composed of a light switch (SW1), a dimmer switch (SW2), etc., both headlamps 3 are high beams. It is connected in parallel with each other (uplight) and low beam (downlight).
상기 라이드스위치(SW1)는 2단계로 작동하게 되어 있으며, 제 1단계는 차량의 미등을 점등시키고, 제 2단계는 헤드램프(3)를 점등시키도록 되어 있다. 상기 라이트스위치(SW1)를 2단계에 위치시킨 상태에서, 손잡이(Knob)를 움직여 내부의 스위치접점이 섭동되어 전원과 접속하게 된다. 또, 디머스위치(SW2)는 라이트의 비임을 바꾸는 스위치로, 운전자가 손으로 손잡이를 전·후로 섭동시켜 상향등 또는 하향 등을 작동시키게 되는 것이다.The ride switch (SW1) is to operate in two stages, the first stage to turn on the taillights of the vehicle, the second stage to turn on the headlamp (3). In the state where the light switch SW1 is positioned in the second step, the knob Knob is moved to perturb the switch contact inside to connect with the power source. In addition, the dimmer switch SW2 is a switch for changing the beam of the light, and the driver operates the uplight or the downlight by perturbing the handle back and forth by hand.
이와 같이, 차량에 설치되어 전방을 비추는 헤드램프(3)의 조작은 운전자가 차량의 시동을 건 상태로 차량을 운행하는 과정에서 라이트스위치(SW1)의 접점을 조절하고 디머스위치(SW2)를 전·후방향으로 운전자가 필요에 따라 헤드램프(3)의 상향등과 하향등을 선택하여 점등시키는 것이다. 특히, 헤드램프(3)는 운전자의 전방시야를 확보하기 위해 배터리전원으로 헤드램프(3)를 점등시켜 전방의 시야를 확보하게 된다.As described above, the operation of the headlamp 3 installed in the vehicle to illuminate the front adjusts the contact point of the light switch SW1 and operates the dimmer switch SW2 in the course of driving the vehicle while the driver starts the vehicle. The driver selects the upper and lower lights of the headlamp 3 and turns them on and off in the forward and backward directions as necessary. In particular, the head lamp 3 is turned on by the battery power to secure the front view of the driver to secure the front view.
그러나, 이와 같이 차량에 설치된 헤드램프(3)는 야간 또는 안개등으로 인하여 전방시야를 확보하지 못하게 될 때 헤드램프가 점등되어 전방시야를 확보하게 되는 것이다. 이러한, 헤드램프(3)가 점등되지 않는 경우엔 전방시야를 확보하게 된다. 따라서, 운전자는 헤드램프(3)가 항상점등되며, 헤드램프(3)를 구동시키는 라이트스위치(SW1)의 조작에 따라 점등되도록 일일점검을 실시해야 하는 불편한 문제점을 갖게 된다.However, when the head lamp 3 installed in the vehicle is unable to secure the front view due to night or fog, the head lamp is turned on to secure the front view. When the head lamp 3 is not turned on, the front field of view is secured. Accordingly, the driver has an inconvenience in that the headlamp 3 is always turned on and the daily inspection is performed so that the headlamp 3 is turned on in accordance with the operation of the light switch SW1 for driving the headlamp 3.
또한, 광원이 없는 지역을 운행하는 과정에서 헤드램프가 점등되지 않은 경우 전방시야를 확보하지 못하게 되므로 주변의 물체와 충돌사고를 유발하게 되는 문제점을 갖게 된다.In addition, if the headlamp is not turned on while driving in an area without a light source, the front vision cannot be secured, thereby causing a crash accident with the surrounding objects.
이에 본 고안은 상기와 같은 문제점을 고려하여 안출된 것으로서, 그 목적은 차량을 운행하는 과정에서 헤드램프의 이상유무에 따라 전류량의 변화로 배터리전원을 스위칭하여 스위칭된 배터리전원에 의해 보조헤드램프를 점등시켜 차량의 전방시야를 확보할 수 있도록 보조램프를 일체로 형성한 헤드램프의 이상유무에 따른 보조램프구동 경고표시장치를 제공함에 있다.The present invention is conceived in consideration of the above problems, the purpose is to switch the battery power to the change in the amount of current in accordance with the presence or absence of the headlamp in the course of driving the vehicle by switching the auxiliary headlamp The present invention provides a supplementary lamp driving warning display device according to the presence or absence of a head lamp in which an auxiliary lamp is integrally formed so as to secure a front view of a vehicle by turning on.
이러한 본 고안의 목적은, 차량의 배터리전원에 의해 구동되며, 전방시야를 확보하기 위해 전방으로 광을 조사되도록 한 헤드램프에 있어서, 헤드램프의 이상유무에 따라 배터리전원을 스위칭하는 스위칭부와, 상기 스위칭부에서 스위칭된 신호에 의해 보조램프를 점등시키는 보조헤드램프와, 상기 스위칭부에서 스위칭된 신호에 의해 헤드램프의 이상유무를 표시하는 표시램프를 포함하여 이루어진 헤드램프의 이상유무에 따른 보조램프구동 경고표시장치에 의해서 달성될 수 있다.An object of the present invention is a head lamp driven by the battery power of the vehicle, the head lamp to irradiate light forward to secure the front view, the switching unit for switching the battery power in accordance with the presence or absence of the head lamp, Auxiliary head lamp comprising an auxiliary head lamp for turning on the auxiliary lamp by the signal switched by the switching unit, and a display lamp for indicating the abnormal state of the head lamp by the signal switched by the switching unit It can be achieved by the lamp drive warning display device.

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 3은 본 고안에 따른 헤드램프의 이상유무에 따른 보조램프구동 경고표시장치의 구성을 보인 회로도이다. 도 3을 살펴보면, 차량의 미등(1) 및 헤드램프(2)를 점등시키기 위한 라이트스위치(10)로, 오프단계(11)와 제 1단계(12)와 제 2단계(13)로 변환되는 접점에 의해 미등 및 헤드램프가 점등된다. 즉, 상기 라이트스위치(10)를 오프단계(11)에서 제 1단계(12)변환하게 되면 배터리전원에 의해 미등이 점등되고, 제 2단계(13)로 변환하게 되면 배터리전원에 의해 헤드램프(3)가 구동되며, 상기 헤드램프(3)를 점등시킨 구동전원은 스위칭부(20)에 입력된다.3 is a circuit diagram showing the configuration of the auxiliary lamp driving warning display device according to the presence or absence of the head lamp according to the present invention. Referring to FIG. 3, the light switch 10 for turning on the taillight 1 and the headlamp 2 of the vehicle is converted into an off stage 11, a first stage 12, and a second stage 13. The taillights and the headlamps are turned on by the contacts. That is, when the light switch 10 is converted from the off step 11 to the first step 12, the tail light is turned on by the battery power, and when the light switch 10 is converted to the second step 13, the headlamp ( 3) is driven, and the driving power that turns on the head lamp 3 is input to the switching unit 20.
상기 스위칭부(20)는 범퍼양측의 헤드램프(3) 보호용 저항(R1,R2)보다 트랜지스터(22,24) 베이스저항(R3,R4)의 저항값을 크게 구성되고, 헤드램프(3)의 구동은 트랜지스터(22,24) 베이스로 흐르는 전류가 작으므로 트랜지스터(22,24)를 턴오프된 상태이다. 이때, 헤드램프의 제 1램프가 단락되면 트랜지스터(24)로 전류량이 증가하게 되고, 트랜지스터(24)베이스로 바이어스전류가 흐르게 되어 배터리전원을 스위칭하게 되며, 스위칭된 신호는 보조헤드램프(30) 및 표시램프(40)에 입력된다.The switching unit 20 has a larger resistance value of the base resistors R3 and R4 of the transistors 22 and 24 than the resistors R1 and R2 for protecting the head lamps 3 on both sides of the bumper. In driving, since the current flowing to the base of the transistors 22 and 24 is small, the transistors 22 and 24 are turned off. At this time, when the first lamp of the head lamp is short-circuited, the amount of current increases to the transistor 24, a bias current flows to the base of the transistor 24 to switch the battery power, and the switched signal is the auxiliary head lamp 30. And input to the display lamp 40.
상기 보조헤드램프(30)는 스위칭부(20)의 각각의 트랜지스터(24)에서 출력된 신호에 따라 보조헤드램프(30)를 점등시켜 전방시야를 확보하게 되고, 보조헤드램프(30)의 오작동으로 방지하기 위해 다이오드(D1,D2)를 설치되며, 설치된 다이오드(D2)로 경류된 신호에 의해 인스트루먼트 패널 일측에 구비된 표시램프(40)를 점등시켜 운전자에게 헤드램프의 이상유무를 알리게 된다. 또한, 헤드램프(3)의 제 2램프가 단락되면 트랜지스터(22)로 전류량이 증가되고, 상기와 같은 작동으로 헤드램프(3)의 이상유무를 표시하게 된다.The auxiliary headlamp 30 turns on the auxiliary headlamp 30 according to a signal output from each transistor 24 of the switching unit 20 to secure a front view, and malfunction of the auxiliary headlamp 30 is caused. The diodes D1 and D2 are installed in order to prevent them, and the display lamp 40 provided on one side of the instrument panel is turned on by the signal flowed through the installed diode D2 to inform the driver of the abnormality of the head lamp. In addition, when the second lamp of the head lamp 3 is short-circuited, the amount of current is increased to the transistor 22, and the above operation indicates whether the head lamp 3 is abnormal.
한편, 헤드램프(3)와 보조헤드램프(30)를 일체로 형성하여 상기 헤드램프(3)가 점등되지 아니하여도 차량의 전방시야를 보조헤드램프(30)로 전방시야를 확보되며, 인스트루먼트 패널에 구비된 표시램프(40)가 점등되어 헤드램프(3)의 이상유무를 운전자에게 알려주게 된다.Meanwhile, the head lamp 3 and the auxiliary head lamp 30 are integrally formed so that the front view of the vehicle is secured to the auxiliary head lamp 30 even when the head lamp 3 is not turned on. The display lamp 40 provided on the panel is turned on to inform the driver of the abnormality of the head lamp 3.
이와 같은 구성을 갖는 본 고안의 작용은, 야간 혹은 안개등으로 전방시야를 확보하지 못하게 될 때 운전자가 전방시야를 확보하기 위해 라이트스위치(10)의 제 2접점(13)을 변환시키게 되면, 차량의 배터리전원에 의해 헤드램프(3)가 점등된다.The operation 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 converts the second contact 13 of the light switch 10 to secure the front view, The head lamp 3 is turned on by the battery power.
이때, 헤드램프(3)의 이상유무에 따라 배터리전원을 스위칭하는 스위칭부(20)에서 범퍼 양측에 구비된 헤드램프(3)의 제 1램프가 단락되면 저항(R1)은 단선된 것이다. 따라서, 스위칭부(20)를 경유하는 제 1루프 저항(R3)보다 제 2루프 저항(R2,R4)이 병렬접속된 상태이므로 저항값이 작아지게 되고, 스위칭부(20)의 트랜지스터(24)로 흐르는 전류량이 증가된다. 상기 트랜지스터(24)의 출력은 보조헤드램프(30) 및 표시램프(40)에 입력된다.At this time, when the first lamp of the head lamp 3 provided on both sides of the bumper is short-circuited in the switching unit 20 for switching the battery power according to the abnormality of the head lamp 3, the resistor R1 is disconnected. Therefore, since the second loop resistors R2 and R4 are connected in parallel with each other than the first loop resistor R3 passing through the switching unit 20, the resistance value is reduced, and the transistor 24 of the switching unit 20 is reduced. The amount of current flowing into the furnace is increased. The output of the transistor 24 is input to the auxiliary head lamp 30 and the display lamp 40.
상기 보조헤드램프(30)는 스위칭부(20)의 트랜지스터(24)에 의해 스위칭된 배터리전원으로 보조헤드램프(30)를 점등시켜 전방시야를 확보하게 되고, 또한 표시램프(40)는 스위칭부(20)의 트랜지스터(24)에 의해 스위칭된 배터리전원으로 인스트루먼트 패널에 구비된 표시램프(40)를 점등시켜 운전자에게 헤드램프의 이상유무를 알리게 된다.The auxiliary head lamp 30 turns on the auxiliary head lamp 30 with the battery power switched by the transistor 24 of the switching unit 20 to secure the front view, and the display lamp 40 is the switching unit. By turning on the display lamp 40 provided in the instrument panel with the battery power switched by the transistor 24 of (20) to inform the driver of the abnormality of the head lamp.
다시 말해, 헤드램프(3)의 이상유무에 따라 스위칭부(20)로 흐르는 전류량의 변화에 의해 스위칭소자(20)의 트랜지스터(22,24)에서 배터리전원이 스위칭되고, 스위칭된 배터리전원으로 보조헤드램프(30)가 구동됨과 동시에 헤드램프(3)의 이상유무를 표시하는 표시램프(40)가 점등되어 운전자에게 헤드램프의 이상유무를 알리게 되는 것이다.In other words, the battery power is switched in the transistors 22 and 24 of the switching element 20 by the change of the amount of current flowing to the switching unit 20 depending on whether there is an abnormality of the head lamp 3, and the auxiliary power is supplied to the switched battery power. At the same time that the head lamp 30 is driven, the display lamp 40 indicating the abnormality of the head lamp 3 is turned on to inform the driver of the abnormality of the head lamp.
이상에서 살펴본 바와 같이 본 고안에 따른 헤드램프의 이상유무에 따른 보조램프구동 경고표시장치는, 야간 또는 안개등으로 인하여 전방시야를 확보하기 위해 헤드램프가 점등되지 않는 경우 헤드램프의 단락에 의해 스위칭부로 흐르는 전류량으로 배터리전원이 스위칭되고, 헤드램프와 일체로 형성된 보조헤드램프를 점등시켜 전방시야를 일정하게 확보되며, 인스트루먼트 패널에 구비된 표시램프를 점등시켜 운전자에게 헤드램프의 이상유무를 알리게 되는 장점을 갖는 장치인 것이다.As described above, the auxiliary lamp driving warning display device according to whether there is an abnormality of the head lamp according to the present invention, when the head lamp is not turned on to secure the front view due to night or fog lights, is switched to the switching unit by a short circuit of the head lamp. The battery power is switched by the amount of current flowing, the auxiliary head lamp formed integrally with the head lamp is turned on to secure the front view constantly, and the indicator lamp provided on the instrument panel is turned on to inform the driver of the abnormality of the head lamp. It is a device having.
