Characterized in that consists of.
이하, 본 발명의 바람직한 실시예를 첨부된 예시도면에 의거하여 상세히 설명한다.Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.
도 2에 도시된 바와같이, 차량용 라이트스위치(1)가 온(ON)/오프(OFF)됨에 따라 점멸되도록 차량의 전측에 좌우로 각각 구비되는 좌우측 헤드램프(2,3)에 있어서,As shown in FIG. 2, in the left and right headlamps 2 and 3 provided on the front and rear sides of the vehicle so that the vehicle light switch 1 blinks as it is turned on / off,
차량의 현재 주행속도를 측정하여 소정의 펄스파를 출력시키는 차속센서(4)와, 상기 차속센서(4)로 부터 소정의 펄스파를 인가받아 High/Low 디지탈신호로 변환시키는 플립플롭회로(5)와, 상기 라이트스위치(1)가 온(ON)/오프(OFF)됨에 따라 일차적으로 단속되는 제 1접속단자(6) 및 상기 플립플롭회로(5)로 부터 소정의 디지탈신호를 인가받아 이차적으로 단속되는 제 2접속단자(7)를 갖는 릴레이(8)와, 상기 제 2접속단자 및 상기 좌우측 헤드램프 사이에 전기적으로 연결되는 저항부(R)로 이루어지게 된다.A vehicle speed sensor 4 for measuring a current traveling speed of a vehicle and outputting a predetermined pulse wave, and a flip-flop circuit 5 for converting a predetermined pulse wave from the vehicle speed sensor 4 into a high / low digital signal 5 And a predetermined digital signal is applied from the first connection terminal 6 and the flip-flop circuit 5, which are primarily interrupted as the light switch 1 is turned on / off. A relay 8 having a second connection terminal 7 intermittently connected to the resistor 8 and a resistor R electrically connected between the second connection terminal and the left and right headlamps.
위와 같이 구성된 본 발명의 작용은 다음과 같다.The operation of the present invention configured as described above is as follows.
차량의 운전자가 차량용 스티어링컬럼(도시되지 않음)의 일측 소정부위에 구비되는 라이트스위치(1)를 온(ON)시켰을 때 우선, 차량이 주행중인 경우에는 상기 라이트스위치(1)에 전기적으로 연결되는 릴레이(8)의 제 1접속단자(6)가 접속되게 되어 차량의 전측에 좌우로 각각 구비되는 좌우측 헤드램프(2,3)가 점등되게 된다When the driver of the vehicle turns on the light switch 1 provided at one side of a vehicle steering column (not shown), the vehicle is electrically connected to the light switch 1 when the vehicle is running. The first connection terminal 6 of the relay 8 is connected so that the left and right headlamps 2, 3 provided on the front side of the vehicle, respectively, are lit.
또한, 이때 차량의 차속센서(4)는 현재의 차속에 상응하는 구형파를 발생하게 되는데 그에 따라 상기 차속센서(4)로 부터 구형파를 인가받은 플립플롭회로(5)는 "High" 신호를 출력하게 된다.In addition, the vehicle speed sensor 4 of the vehicle generates a square wave corresponding to the current vehicle speed. Accordingly, the flip-flop circuit 5 receiving the square wave from the vehicle speed sensor 4 outputs a "High" signal. do.
따라서, 차량이 주행상태인 경우에 상기 플립플롭회로(5)의 출력신호는 계속해서 "High" 상태가 유지되므로 상기 제 1접속단자(6)에 의해 릴레이(8)의 접속상태가 유지되게 된다.Therefore, when the vehicle is in a running state, the output signal of the flip-flop circuit 5 is continuously maintained in the "High" state, so that the connection state of the relay 8 is maintained by the first connection terminal 6. .
그러나, 차량으로 주행도중 보행자를 위한 건널목 또는 교차로에서 신호대기를 하기 위해 정차를 하게 되면 상기 차속센서(4)로 부터 구형파가 발생되지 않게 되는데 이때, 상기 릴레이(8)의 제 2접속단자(7)가 접속되게 된다.However, when the vehicle stops to wait for a signal at a crossing or an intersection for a pedestrian while driving in a vehicle, a square wave is not generated from the vehicle speed sensor 4, and at this time, the second connection terminal 7 of the relay 8 is stopped. ) Will be connected.
그에 따라서, 상기 좌우측 헤드램프(2,3)에 공급되던 전류가 상기 제 2접속단자(7)에 전기적으로 연결되는 저항부(R)를 거치면서 소모되어 상기 좌우측 헤드램프(2,3)의 광량이 줄어들게 된다.Accordingly, the current supplied to the left and right headlamps 2 and 3 is consumed while passing through the resistor portion R electrically connected to the second connection terminal 7. The amount of light will be reduced.
참고적으로, 도 3은 상기 플립플롭회로(5)의 입,출력신호를 나타내는 다이아그램이다.For reference, FIG. 3 is a diagram illustrating input and output signals of the flip-flop circuit 5.
위와같이, 본 발명에 의한 차량용 헤드램프 자동광량조절회로는 야간에 차량운행시 주행중에는 차량의 전측에 좌우로 각각 구비되는 좌우측 헤드램프(2,3)의 광량을 정상적으로 유지시키고 정차시에는 자동적으로 상기 좌우측 헤드램프(2,3)의 광량을 줄여 줌으로써 차량운행시 차량 운전자의 수동조작 없이도 상기 좌우측 헤드램프(2,3)의 광량을 조절할 수 있게 되는 효과가 있다.As described above, the vehicle headlamp automatic light amount control circuit according to the present invention normally maintains the light amount of the left and right headlamps 2 and 3 which are provided on the front and rear sides of the vehicle while driving at night, and automatically when stopped. By reducing the light amount of the left and right headlamps (2,3) it is possible to adjust the amount of light of the left and right headlamps (2,3) without manual operation of the vehicle driver during vehicle operation.
