종래에는 운전자가 차량주위 또는 차량전방의 배경광량에 따라 임의로 차량내부에 설치된 전조등 절환스위치(도시생략)를 통해 수동조작하여 이상적으로 전방시야를 확보할 수 있는 상향등 또는 하향등을 선택하여 운행하였다. 만약 운전자가 하향 전조등을 선택할 경우에는 제1도에 도시한 바와 같이 제어모터(1)가 동작하여 이 제어모터(1)와 연결하여 절환식 차광판(2)이 절환동작하여 광원(3)이 멀리나가지 못하고 차량 시야의 근거리를 비추게 되며, 전조등 절환스위치를 조작하여 상향 전조등을 선택할 경우에는 차광판(2)이 소정각도로 이동되어 차량시야의 원거리를 빛게 된다.In the related art, a driver manually operates an uplight or a downlight to manually secure a front view by manually operating a headlight switching switch (not shown) installed in the vehicle according to the amount of background light around the vehicle or the front of the vehicle. If the driver selects the downlight, as shown in FIG. 1, the control motor 1 is operated to be connected to the control motor 1 so that the switchable light shield plate 2 is switched so that the light source 3 is farther away. The vehicle is not able to go out and reflects a near field of view of the vehicle, and when the upper headlight is selected by operating the headlight switching switch, the light shield plate 2 is moved at a predetermined angle to shine a long distance of the vehicle field of view.
이와 같이 종래의 차량전조등은 그 조사각도가 이원화로 고정되어 있기 때문에 운전자의 차량전방시야의 확보가 제한되는 문제점과, 차량운행 중 수동조작으로 인한 불편함이 내재되는 문제점을 안게 된다.As described above, the conventional vehicle headlamp has a problem in that the driver's front field of view is restricted because the irradiation angle is fixed in dual and inconvenience due to manual operation during driving of the vehicle.
본 발명은 상기 제반 문제점을 해결하기 위하여 안출된 것으로, 차량주위 또는 차량전방의 배경광량에 따라 자동적으로 전조등이 상하방향으로 스텝적 이동을 하도록 하여 운전자의 전방시야를 이상적으로 확보할 수 있도록 하는데 그 목적이 있다.The present invention has been made to solve the above problems, the headlights to automatically move step by step in the vertical direction in accordance with the amount of background light around the vehicle or the front of the vehicle to ensure an ideal front view of the driver There is a purpose.

이하, 본 발명의 바람직한 실시예를 첨부된 도면에 의거 상세히 설명하면 다음과 같다.Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.
제2도는 본 발명의 전조등을 설명하기 위한 구성도이고, 제3도는 본 발명의 차량 전조등 조명거리 자동 조정장치의 블록 다이어그램으로서, 차량전방 소정의 위치에 설치되어 전방광량을 감지하기 위한 광감지센서(10)를 통해 감지된 아날로그 신호전압이 A/D컨버터(20)를 통해 디지탈전압으로 변환되도록 하고, 상기 A/D컨버터(20)를 통한 디지털 신호가 제어유닛(30)에 입력되도록 연결하여 디지털 신호에 의한 전방 배경광량이 계산되고 계산된 광량에 해당하는 제어신호가 스텝모터(40)에 출력되도록 연결하며, 각 전조등(50)근방 소정의 위치에 스텝모터(40)가 설치되어 이 스텝모터(40)의 구동에 의해 각 전조등(50)이 연동되도록 구성된다.2 is a block diagram illustrating the headlight of the present invention, and FIG. 3 is a block diagram of the automatic headlight illumination distance adjusting device of the present invention, and is provided at a predetermined position in front of a vehicle to detect a front light amount. The analog signal voltage sensed through 10 is converted to a digital voltage through the A / D converter 20, and the digital signal through the A / D converter 20 is connected to be input to the control unit 30. The front background light amount calculated by the digital signal is connected and the control signal corresponding to the calculated light amount is output to the step motor 40. The step motor 40 is installed at a predetermined position near each headlamp 50, and this step is performed. Each headlamp 50 is configured to be interlocked by the driving of the motor 40.
이와 같이 구성된 본 발명은 차량전방 주위에 배경광량이 매우 많은 도로(예를 들어, 다수의 가로등이 설치되고 차량의 통행이 빈번한 도로)를 주행할 경우, 차량전방 소정의 위치에 설치된 광감지센서(10)를 통해 주위환경의 배경광량을 감지하여 이에 해당하는 아날로그 신호전압을 A/D컨버터(20)에 입력한다.According to the present invention configured as described above, when driving a road having a large amount of background light around the front of the vehicle (for example, a road in which a plurality of street lights are installed and frequent traffic of the vehicle), the light detecting sensor installed at a predetermined position in front of the vehicle 10) detects the amount of background light of the surrounding environment and inputs the analog signal voltage corresponding to the A / D converter 20.
A/D컨버터(20)에 입력된 아날로그 신호전압은 디지털 신호전압으로 변환되고 이 신호는 제어유닛(30)에 입력되어 주위 배경광량을 계산하게 된다. 이와 같이 계산된 값에 따라 해당되는 신호를 스텝모터(40)로 출력하여 이 스텝모터(40)를 구동시킨다.The analog signal voltage input to the A / D converter 20 is converted into a digital signal voltage and this signal is input to the control unit 30 to calculate the amount of ambient background light. The step motor 40 is driven by outputting a corresponding signal to the step motor 40 according to the calculated value.
이때 스텝모터(40)와 연동되어 동작하는 각 전조등(50)의 조사각도는 조명거리가 짧은 하향등의 위치를 취하게 된다.At this time, the irradiation angle of each of the headlamps 50 operating in conjunction with the step motor 40 takes the position of the downlights with a short illumination distance.
반면에, 차량전방 주위의 배경광량이 상술한 것보다는 작지만 어느정도 시야 이상적으로 확보가 용이한 도로를 주행하게 되면 광감지센서(10)는 이와 같은 주위환경의 배경광량을 감지하여 이에 해당하는 아날로그 신호전압을 A/D컨버터(20)에 입력하고, 이 A/D컨버터(20)에 입력된 아날로그 신호전압은 디지털 신호전압으로 변환되어 제어유닛(30)에 입력되어 주위 배경광량을 계산하게 된다. 이와 같이 계산된 값에 따라 해당하는 신호를 스텝모터(40)로 출력하여 이 스텝모터(40)를 구동시킨다. 이때 스텝모터(40)와 연동되어 동작하는 각 전조등(50)의 조사각도는 조명거리가 전술한 하향등의 위치에서 상향으로 약간 올라간 위치를 취하게 된다.On the other hand, if the amount of background light around the front of the vehicle is smaller than the above, but traveling on a road that is easily secured to some extent, the light sensor 10 detects the amount of background light of the surrounding environment and corresponds to the analog signal. The voltage is input to the A / D converter 20, and the analog signal voltage input to the A / D converter 20 is converted into a digital signal voltage and input to the control unit 30 to calculate the amount of ambient background light. The corresponding signal is output to the step motor 40 according to the calculated value to drive the step motor 40. At this time, the irradiation angle of each of the headlamps 50 operating in conjunction with the step motor 40 takes a position where the illumination distance is slightly raised upward from the above-described position of the downlight.
만약, 주위의 배경광량이 매우 적은 도로(예를 들어, 가로등이 설치되어 있지 않고 차량의 통행이 거의 없는 도로)를 주행할 경우, 광감지센서(10)를 통해 이와 같은 주위환경의 배경광량을 감지하여 이에 해당하는 아날로그 신호전압을 A/D컨버터(20)에 입력하고, 이 A/D컨버터(20)에 입력된 아날로그 신호전압은 디지털 신호전압으로 변환되어 제어유닛(30)에 입력되어 주위 배경광량을 계산하게 된다. 이와 같이 계산된 값에 따라 해당되는 신호를 스텝모터(40)로 출력하여 이 스텝모터(40)를 구동시키고 이에 의해 스텝모터(40)와 연동되어 동작하는 각 전조등(50)의 조사각도는 조명거리가 매우 긴 상향등의 위치를 취하게 된다.If the vehicle is traveling on a road having a very small amount of background light (for example, a road where no street light is installed and a vehicle rarely passes), the amount of background light of the surrounding environment is measured through the light sensor 10. Detects and inputs the analog signal voltage corresponding to the A / D converter 20. The analog signal voltage input to the A / D converter 20 is converted into a digital signal voltage and input to the control unit 30. The background light amount is calculated. According to the calculated value, the corresponding signal is output to the step motor 40 to drive the step motor 40, whereby the irradiation angle of each headlamp 50 operating in conjunction with the step motor 40 is illuminated. It takes the position of a very high uplight.
즉, 광감지 센서(10)를 통해 감지되는 외부환경의 광량에 따라 제어유닛(30)이 이에 해당하는 만큼 스텝모터(40)를 스텝별로 동작시키도록 하여 자동으로 전조등이 가장 이상적인 조명거리를 확보하게 되는 것이다.That is, according to the amount of light of the external environment detected by the light sensor 10, the control unit 30 to operate the step motor 40 for each step corresponding to this automatically, the headlamp automatically secures the most ideal illumination distance Will be done.
상술한 바와 같이 본 발명은 차량주위 또는 차량전방의 배경광량에 따라 자동적으로 전조등이 상하방향으로 스텝적 이동을 하도록 함으로써 운전자의 전방시야를 이상적으로 확보할 수 있을 뿐만 아니라 운전자의 편의성을 보장할 수 있도록 하는데 유용한 효과가 있다.As described above, according to the present invention, the headlight automatically moves stepwise in the vertical direction according to the amount of background light around the vehicle or the front of the vehicle, thereby ideally securing the driver's front view and ensuring the driver's convenience. It has a useful effect.
