일반적으로 자동차의 전조등은 상향등과 하향등으로 구분되며, 운전자의 필요에 따라서 야간 운전 시에 전방 시야를 확보하기 위해 사용되는 조명 장치로서, 운전자의 스위치 조작에 의해서 온/오프가 이루어 진다. 또한 대향차와 교차할 때 눈부심을 주지않는 성능을 가지고 있어야 하며, 전조등의 밝기는 법령으로 정해져 있는데, KS 규격에 의하면 주행빔의 주행축에 있어어 20000 cd 이상으로 규정되어 있다.In general, the headlights of a vehicle are classified into an uplight and a downlight, and are used as a lighting device to secure a forward view when driving at night according to a driver's need, and are turned on / off by a driver's switch operation. In addition, it must have the performance that does not give glare when crossing the opposite car, and the brightness of the headlight is determined by the law, and according to the KS standard, the driving axis of the driving beam is defined as more than 20000 cd.

여기서 cd는 광도의 단위로서 Candle의 약어이며, 그 의미는 광원에서 1m 떨어진 1㎡의 면에 1루멘(lm)의 광속이 통과할 때 그 방향의 빛이 세기를 뜻한다.Here, cd is an abbreviation of Candle as a unit of brightness, and the meaning is the intensity of light in that direction when a luminous flux of 1 lumen (lm) passes through a surface of 1 m 2 away from a light source.

하지만 상기와 같은 광도 규격에 따른 전조등을 사용한다 하더라도 실제 야간 주행 시에는 대향 차량의 운전자에게 순간적인 시각적인 장애를 주게되며, 특히 초보 운전자나 야간 운전 능력이 떨어지는 운전자가 보다 밝은 시야 확보를 위해 대향 차량에 대해 무관심한 상태로 전조등을 상향으로 조절하여 주행을 하는 경우 사고를 발생시킬 수 있는 문제점이 있다.However, even when headlights according to the above-described brightness standards are used, the driver of the opposing vehicle may have a momentary visual impediment during the actual night driving, and especially a novice driver or a driver with low night driving ability may face a brighter view. There is a problem that may cause an accident when driving by adjusting the headlight upward in a state of indifference to the vehicle.

이에, 상기와 같은 문제점을 해결하기 위해서 본 발명은 운전자가 전방 시야 확보를 위해 전조등을 상향 혹은 하향으로 켜고 주행을 할때, 전방에서 교차하는 대향 차량의 광도를 감지하여 전조등의 광도를 일정 시간 동안 감소시키도록 된 자동차 전조등의 광도 조절 장치를 제공하는데 그 목적이 있다.Thus, in order to solve the above problems, the present invention, when the driver turns the headlights up or down to secure the front view when driving, by detecting the brightness of the opposite vehicle crosses in front of the front for a predetermined time It is an object of the present invention to provide a brightness control device for an automobile headlamp that is to be reduced.

이하, 첨부된 도면을 참조하여 본 발명의 바람직한 실시예를 상세히 설명한다.Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

제1도는 본 발명에 따른 자동차 전조등의 광도 조절 장치의 구성을 도시한 회로도이다.1 is a circuit diagram showing the configuration of a brightness control apparatus for a vehicle headlamp according to the present invention.

제1도에서 도시된 바와 같이, 본 발명의 실시예는 전조등(10)과; 대향 차량의 광도를 감지하는 대향등 광도 센서(20); 상기 전조등(10)을 온/오프 시키는 라이트 스위치(30); 상기 라이트 스위치(30)의 동작에 의해 온/오프 되는 전조등 릴레이(40); 상기 전조등(10)의 조명 방향을 상향 혹은 하향으로 변화시키는 딤머 스위치(50) 및; 상기 전조등(10)의 광도를 일정 시간 동안 감소시키는 광도 조절 릴레이(60)로 구성된다. 또한, 상기 전조등(10)은 우측 하향등(11)과 좌측 하향등(12), 우측 상향등(13) 및 좌측 상향등(14)으로 구성되며, 상기 광도 조절 릴레이(60)는 하향등 조절 릴레이(61)와 상향등 조절 릴레이(62)로 구성된다.As shown in FIG. 1, an embodiment of the present invention includes a headlamp 10; A counter light intensity sensor 20 for detecting a light intensity of an opposing vehicle; A light switch 30 for turning on / off the headlamp 10; Headlight relay 40 that is turned on / off by the operation of the light switch 30; A dimmer switch 50 for changing the illumination direction of the headlamp 10 upwardly or downwardly; It consists of a brightness control relay 60 for reducing the brightness of the headlamp 10 for a predetermined time. In addition, the headlamp 10 is composed of a right downlight 11, a left downlight 12, a right uplight 13 and a left uplight 14, the brightness control relay 60 is a downlight control relay ( 61) and the high beam control relay 62.

상기와 같이 구성된 본 발명의 바람직한 실시예의 작용 및 효과는 다음과 같다.Actions and effects of the preferred embodiment of the present invention configured as described above are as follows.

먼저 상기 좌우측 하향등(11, 12)과 상기 좌우측 상향등(13, 14)이 모두 정상적으로 작동하는 상태에서 상기 전조등(10)을 켜기 위해서 상기 라이트 스위치(30)를 온 하면 상기 전조등 릴레이(40)가 온 되고, 상기 딤머 스위치(50)가 하향(Lo) 혹은 상향(Hi)의 위치 중 어떤 위치에 있는가에 따라서 상기 전조등(10) 중의 상기 좌우측 하향등(11, 12) 혹은 상기 좌우측 상향등(13, 14)이 켜지게 되며, 특히 상기 상향등(13, 14)이 켜지게 되면 자동차 계기판에 있는 상기 상향 지시등(22)에 불이 들어와서 현재 상기 전조등(10)의 위치가 상향에 있음을 알려 주게 된다.First, when the light switch 30 is turned on to turn on the headlamp 10 in a state in which both the left and right downward lights 11 and 12 and the left and right upward lights 13 and 14 operate normally, the headlight relay 40 is turned on. The left and right downward lights 11 and 12 or the left and right upward lights 13, among the headlamps 10, depending on whether the dimmer switch 50 is in the downward (Lo) or upward (Hi) position. 14) is turned on, and in particular, when the upper lights (13, 14) is turned on, the upper indicator light 22 on the dashboard of the vehicle lights up to indicate that the current position of the headlight (10) is up. .

이때, 대향 차량으로부터 빛이 감지되지 않을 경우,상기 하향등 조절 릴레이(61) 혹은 상향등 조절 릴레이(62)가 오프되어 B+전원이 직접 상기 전조등(10)에 연결되며, 따라서 상기 전조등(10)은 상대적으로 밝은 빛을 발생한다.In this case, when the light is not detected from the opposite vehicle, the downlight control relay 61 or the uplight control relay 62 is turned off so that the B + power is directly connected to the headlamp 10, and thus the headlamp 10 is Generates relatively bright light.

만약, 상기와 같은 상태에서 상기 전조등(10)이 켜져 있는 대향 차량이 교차하게 되면, 상기 광도 센서(20)가 대향 차량의 빛을 받아 전류를 상기 광도 조절 릴레이(60)로 흘려 보내게 되는데, 현재 상기 전조등(10)의 온 상태가 하향이면 상기 하향등 광도 센서(21)가 대향 차량의 전조등(10) 빛을 감지하게 되고, 상기 전조등(10)의 온 상태가 상향이면 상기 상향등 광도 센서(22)가 대향 차량의 전조등(10) 빛을 감지하게 되어, 상기 하향등 조절 릴레이(61) 혹은 상기 상향등 조절 릴레이(62)로 전류가 흐르게 된다.If the opposite vehicle in which the headlamp 10 is turned on in the above state crosses the light sensor 20 receives the light of the opposite vehicle and sends a current to the light control relay 60. When the current state of the headlight 10 is downward, the downlight intensity sensor 21 detects the light of the headlight 10 of the opposite vehicle. When the state of the headlight 10 is upward, the upward light intensity sensor ( 22 detects the headlight 10 light of the opposite vehicle, and a current flows to the downlight control relay 61 or the uplight control relay 62.

이에 따라서 상기 하향등 조절 릴레이(61) 혹은 상향등 조절 릴레이(62)가 온 되는데, 이때 B+전류는 상기 좌우측 하향등(11, 12)의 경우 저항 R1을 통해 흐르게 되고, 상기 좌우측 상향등(13, 14)의 경우 저항 R2를 통해 흐르게 된다.Accordingly, the downlight control relay 61 or the uplight control relay 62 is turned on. In this case, the B + current flows through the resistor R1 in the case of the left and right downlights 11 and 12, and the left and right uplights 13 and 14. ) Flows through the resistor R2.

이렇게 되면 상기 좌우측 하향등(11, 12) 혹은 상기 좌우측 상향등(13, 14)으로 흐르는 전류가 저항에 의해 감소되어 상기 하향등 조절 릴레이(61) 혹은 상향등 조절 릴레이(62)가 오프되었을 때보다 광도가 줄어 들게 된다.(예컨대, 표준광도 20000 cd로 광도로 줄어 든다.)In this case, the current flowing to the left and right downlights 11 and 12 or the left and right uplights 13 and 14 is reduced by a resistance, and thus the luminous intensity is lower than when the downlight control relay 61 or the uplight control relay 62 is turned off. (E.g., standard brightness is reduced to 20000 cd).

또한, 상기 광도 조절 릴레이(60)는 일정 시간 동안만 전류를 흘려 보내고 나서 다시 오프 되므로, 대향 차량이 지나가고 나면 상기 전조등(10)은 본래의 상태로 복귀하여 하향 혹은 상향으로 전방에 빛을 비추게 된다.In addition, the brightness control relay 60 is turned off again after passing a current for only a predetermined time, so that the headlight 10 is returned to its original state after the opposing vehicle passes to shed light forward or downward do.

이상에서 살펴 본 바와 같이, 본 발명에 따르면 야간 운전 시에 전조등을 켠 상태로 교차하여 지나가는 대향 차량의 감도를 감지하여 일정 시간 동안(예컨대, 대향 차량이 지나가는 수초 동안) 전조등의 광도를 감쇠시킴으로써, 상대 차량 운전자의 시각적인 장애를 해소하여 사고를 예방하는 효과가 있다.As described above, according to the present invention, by detecting the sensitivity of the opposite vehicle passing by crossing the headlights on at night driving, by attenuating the brightness of the headlights for a predetermined time (for example, several seconds while the opposite vehicle passes), It is effective in preventing accidents by eliminating visual obstacles of the other vehicle driver.
