위와같이 구성된 본 발명의 작용은 다음과 같다.The operation of the present invention configured as described above is as follows.

즉, 차량으로 주행시 도로상에 안개가 짙게 깔렸을 때 차량의 전방측 밝기에 따라 자동으로 차량의 전측에 좌우로 각각 구비되는 좌우측 포그램프(1, 2)를 점등 또는 소등시키고자 하는 경우에 본 발명에 의한 조도센서를 이용한 차량용 포그램프의 스위칭회로를 적용하게 되면 우선, 제1도에 도시된 바와같이 종래에는 차량의 운전자가 차량용 인스트루먼트판넬(도면에 도시되지 않음)의 일측 소정부위에 구비되는 포그램프스위치(3)를 온(ON)시키면 그에 따라 차량용 계기판(도면에 도시되지 않음)의 일측 소정부위에 구비되는 포그램프점등확인등(4)이 점등됨과 동시에 상기 포그램프스위치(3)에 전기적으로 연결되는 제1포그램프릴레이(6)가 작동되어 상기 좌우측 포그램프(1, 2)가 점등되게 된다.That is, when the left and right fog lamps 1 and 2, which are respectively provided to the left and right of the front side of the vehicle, are turned on or off according to the brightness of the front side of the vehicle when the fog is deeply placed on the road at the time of driving on the vehicle, When a switching circuit of a vehicle fog lamp using the illuminance sensor according to the present invention is applied, as shown in FIG. 1, a driver of a vehicle is conventionally provided at a predetermined portion of a vehicle instrument panel (not shown) When the fog lamp switch 3 is turned on, a fog lamp lighting check lamp 4 provided at a predetermined position on one side of a vehicle instrument panel (not shown) is turned on and at the same time, The first fog lamp relay 6 electrically connected is operated to turn on the left and right fog lamps 1 and 2.

그러나 본 발명에서는 차량의 전측 소정부위에 조도센서(7)를 추가적으로 구비하여 차량의 전방측 밝기를 감지하게 되는데 이때, 상기 조도센서(7)에 의해 차량의 전방측 밝기가 감지된 후에는 상기 조도센서(7)에 전기적으로 연결되는 비교기(8)가 상기 조도센서에 의해 감지된 차량의 전방측 밝기가 일정 럭스(Lux)이상인지를 비교하게 된다.However, in the present invention, the illuminance sensor 7 is further provided at a predetermined area on the front side of the vehicle to sense the front side brightness of the vehicle. After the front side brightness of the vehicle is detected by the illuminance sensor 7, The comparator 8 electrically connected to the sensor 7 compares whether the brightness of the front side of the vehicle sensed by the illuminance sensor is equal to or greater than a certain Lux.

즉, 상기 비교기(8)는 예컨데 5000럭스이하일 때에는 출력신호를 High로 보내고 그 이상일 경우에는 Low로 보내게 된다.That is, the comparator 8 sends the output signal High when the output voltage of the comparator 8 is less than 5000 lux, and outputs the output signal Low when the output voltage is higher than 5000 lux.

그에 따라서, 상기 비교기(8)의 출력신호가 Low일 경우에는 상기 비교기(8)에 전기적으로 연결되어 스위칭작용을 하는 트랜지스터(9)가 동작되지 않고 High일 경우에는 상기 트랜지스터(9)가 동작되게 되어 상기 트랜지스터(9)에 전기적으로 연결되는 제2포그램프릴레이(10)가 작동되게 되는데 그에 따라 상기 제2포그램프릴레이(10)에 전기적으로 연결되는 상기 좌우측 포그램프(1, 2)가 점등되게 된다.Accordingly, when the output signal of the comparator 8 is Low, the transistor 9, which is electrically connected to the comparator 8 to perform the switching operation, is not operated. When the output signal of the comparator 8 is High, The second fog lamp relay 10 electrically connected to the transistor 9 is activated so that the left and right fog lamps 1 and 2 electrically connected to the second fog lamp relay 10 are turned on .

위와같이, 본 발명에 의한 조도센서를 이용한 차량용 포그램프의 스위칭회로는 차량용 포그램프스위치(3), 제1, 2포그램프릴레이(6, 10) 및 좌우측 포그램프(1, 2)로 이루어지는 차량용 포그램프 스위칭회로에 별도로 조도센서(7)를 구비하여 자동으로 차량의 전방측 밝기가 일정 럭스이상일 때에는 상기 좌우측포그램프(1, 2)를 소등시키고 일정 럭스미만일 때에는 점등시킴으로써 상기 좌우측 포그램프(1, 2)의 전력소모로 인한 밧데리의 방전을 방지함과 더불어 차량의 운전자가 번거롭게 상기 포그램프스위치(3)를 온/오프시킬 필요가 없게 되는 효과가 있다.As described above, the switching circuit of the vehicle fog lamp using the illuminance sensor according to the present invention is composed of the vehicle fog lamp switch 3, the first and second fog lamp relays 6 and 10, and the left and right fog lamps 1 and 2, The left and right fog lamps 1 and 2 are turned off when the brightness of the front side of the vehicle is automatically set to be equal to or greater than a certain lux, And 2), and it is unnecessary for the driver of the vehicle to turn the fog lamp switch 3 on and off troublesomely.
