보조램프를 갖는 차량용 2중램프 점등장치Vehicle double lamp lighting device with auxiliary lamp

본 고안은 보조램프를 갖는 차량용 2중램프 점등장치에 관한 것으로서, 보다 상세하게는 차량의 각종램프를 메인램프와 보조램프를 일체로 형성하고, 메인램프의 광을 감지하고, 감지된 광신호에 의해 보조램프를 점소등시킴과 동시에 메인램프의 이상유무를 표시하는 표시램프로 메인램프의 이상유무를 표시하도록 한 보조램프를 갖는 차량용 2중램프 점등장치에 관한 것이다.The present invention relates to a vehicle dual lamp lighting device having an auxiliary lamp, and more particularly, to form various lamps of the vehicle integrally with the main lamp and the auxiliary lamp, to detect the light of the main lamp, and to the detected optical signal The present invention relates to a vehicle double lamp lighting device having an auxiliary lamp which turns on and off an auxiliary lamp and displays an abnormal state of the main lamp with a display lamp which indicates whether or not the main lamp is abnormal.

일반적으로 차량에는 배터리전원에 의해 점소등되는 램프가 구비되고, 각 램프의 기능에 따라 운전자가 램프를 점등시키는 각 스위치접점을 브레이크상태로 변환하게 되면 변환된 접점으로 배터리전원이 공급된다. 따라서, 다른 차량의 운전자들에게 차량의 진행방향(방향지시등), 긴급상황(비상등), 감속 및 제동등(브레이크) 등의 램프를 점등시키게 되는 조명장치가 구비되고, 상기 조명장치를 점소등시키는 스위치의 접점에 의해 차량을 운행하는 과정에서 현재상태를 각 램프를 점등시켜 다른 차량의 운전자에게 알리도록 차량의 전후방에 다수의 램프가 설치된다.In general, a vehicle is provided with a lamp that is turned on and off by battery power, and according to the function of each lamp, when the driver converts each switch contact for turning on the lamp into a brake state, the battery power is supplied to the converted contact. Therefore, a lighting device is provided to the drivers of other vehicles to turn on lamps such as the driving direction (direction indicator), emergency situation (emergency light), deceleration and braking light (brake) of the vehicle, and the switch to turn off the lighting device. A plurality of lamps are installed in front and rear of the vehicle to notify each driver of another vehicle by lighting each lamp in the process of driving the vehicle by the contact point of.

또한, 공지된 바와 같이 주변 밝기를 감지하는 소자(Cadmiumsulfide : 이하 CDS함)로, 포토트랜지스터의 일정으로 주변의 광을 감지하여 감지된 신호에 따라 저항값이 변화되는 소자이다. 즉, 주변의 밝기에 따라 제로(0)에서 무한대(∝)로 변화되고, 주간에는 저항값이 제로(0)에 가까우며, 야간에는 저항값이 무한대(∝)에 가깝게 된다. 상기 CDS를 사용하는 회로는 전자알람 또는 가로등으로, 주변의 밝기를 감지하여 멜로디음을 발생시키는 장치 등에 사용되며, 현재는 포토트랜지스터 또는 포토다이오드를 등으로 대치되어 많이 사용된다.In addition, as known, a device for detecting ambient brightness (Cadmiumsulfide: referred to as CDS) is a device in which a resistance value is changed according to a detected signal by sensing ambient light with a constant of a phototransistor. That is, it changes from zero (0) to infinity according to the surrounding brightness, the resistance value is close to zero during the day, and the resistance value is close to infinity at night. The circuit using the CDS is an electronic alarm or a street lamp, and is used in a device for generating a melody sound by sensing the brightness of the surroundings, and is currently replaced by a phototransistor or a photodiode.

이와 같이 차량에 구비된 조명장치에는 고유의 기능을 가지며, 그에 따라 운전자가 인스트루먼트 패널에 구비된 스위치를 이용하여 각각의 램프를 점등시키게 된다. 따라서, 야간 또는 안개등으로 전방시야를 확보하기 위해서는 차량의 정면 범퍼 양측으로 구비된 헤드램프를 점등시켜 전방시야를 확보하게 된다. 또한, 긴급상황을 표시하는 램프로 다른 차량의 주의 및 추돌을 피하기 위하여 전후, 좌우의 방향 지시등과 보조 방향 지시등(보조 플래시)이 동시에 점멸하기 위한 해저드플래시(Hazard flash:고장표시등 혹은 비상점멸등) 램프가 구비되어 차량의 고장과 추돌사고 및 긴급상황을 표시하게 된다. 따라서, 운전자가 차량의 비상등을 점등시켜 차량의 긴급상황을 외부로 표시하게 된다.As such, the lighting device provided in the vehicle has a unique function, and accordingly, the driver turns on each lamp by using a switch provided in the instrument panel. Therefore, in order to secure the front view at night or fog light, the head lamps provided at both sides of the front bumper of the vehicle are turned on to secure the front view. In addition, the Hazard flash (flashing lamp or emergency flashing light) to simultaneously flash the front and rear, left and right direction indicators and the auxiliary direction indicator (secondary flash) to avoid the caution and collision of other vehicles with the lamp indicating an emergency situation. Lamps are provided to indicate vehicle failures, collisions, and emergencies. Therefore, the driver turns on the emergency light of the vehicle to display the emergency situation of the vehicle to the outside.

그러나, 이와 같은 차량에 구비된 각종램프는 운전자가 차량을 운행하는 과정에서 램프를 점소등시켜 운행중인 차량의 현재상황을 외부로 표시하여 다른 차량의 운전자가 현재상황을 알리게 되지만, 상기 운전자가 차량의 진행방향이나 긴급상황을 표시하기 위해 스위치조작으로 램프를 점등시키게 될 때 각종램프가 점등되지 않는 경우에는 다른 차량의 운전자는 운행중인 현재상황을 알지 못하게 문제점을 갖게 된다.However, the various lamps provided in such a vehicle may turn off the lamp while the driver is driving the vehicle to display the current situation of the vehicle being driven to the outside so that the driver of the other vehicle may inform the current situation. When various lamps are not turned on when the lamp is turned on by a switch operation to display the driving direction or an emergency situation, the driver of another vehicle may have a problem not knowing the current situation in operation.

또한, 운전자가 각종램프가 점등된 상태를 실내에서 용이하게 식별할 수 없는 상태에서 임의의 방향으로 변환하게 될 때 다른 차량의 운전자는 돌발적인 상황에 의해 급제동을 하거나 다른 차선으로 차선 등을 변경하게 되는 등 다른 차량과의 추돌 및 총돌사고를 유발하게 되는 문제점을 갖게 된다.In addition, when the driver converts a state in which various lamps are turned on in an arbitrary direction without being easily identified indoors, the driver of another vehicle may suddenly brake or change lanes to another lane due to an accidental situation. There is a problem that will cause collisions and other accidents with other vehicles.

따라서, 각종램프의 점등된 상태를 감지하여 감지된 신호로 운전자에게 램프의 이상유무를 알리게 되는 장치를 필요로하게 된다.Therefore, there is a need for a device that detects the lighting state of various lamps and informs the driver of the abnormality of the lamp by the detected signal.

이에 본 고안은 상기와 같은 문제점을 고려하여 안출된 것으로서, 그 목적은 차량의 각종램프를 메인램프와 보조램프를 일체로 형성하고, 메인램프의 광을 감지하고, 감지된 광신호에 의해 보조램프를 점소등시킴과 동시에 메인램프의 이상유무를 표시하는 표시램프로 메인램프의 이상유무를 표시하도록 한 보조램프를 갖는 차량용 2중램프 점등장치를 제공함에 있다.The present invention is conceived in view of the above problems, the purpose is to form a variety of lamps of the vehicle main lamp and the auxiliary lamp integrally, to detect the light of the main lamp, the auxiliary lamp by the detected light signal The present invention provides a dual lamp lighting device for a vehicle having an auxiliary lamp which turns on and off and at the same time a display lamp indicating an abnormality of the main lamp.

이러한 본 고안의 목적은, 차량의 배터리전원에 의해 점소등되도록 메인램프와 보조램프를 일체로 형성한 2중램프와, 상기 메인램프의 광을 감지하며, 감지된 신호를 반전시켜 보조램프를 점소등시키는 보조램프구동부와, 상기 메인램프의 이상유무에 따라 램프로 입력되는 배터리전원을 바이패스시켜 메인램프의 이상유무를 표시하는 램프이상유무표시부를 포함하여 이루어진 보조램프를 갖는 차량용 2중램프 점등장치에 의해서 달성될 수 있다.The object of the present invention, the dual lamp which is integrally formed with the main lamp and the auxiliary lamp to be turned on by the battery power of the vehicle, and detects the light of the main lamp, and inverts the detected signal to point the auxiliary lamp Turn on the vehicle's dual lamp having an auxiliary lamp driving unit to turn off and a lamp including a lamp abnormality display unit for bypassing the battery power input to the lamp in accordance with the abnormality of the main lamp to indicate the abnormality of the main lamp It can be achieved by the 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 1은 본 고안에 따른 보조램프를 갖는 차량용 2중램프 점등장치의 구성을 보인 회로도이다. 도 1을 살펴보면, 차량의 시동을 건 상태로 라이트스위치접점에 의해 작동되는 램프(헤드램프)와, 운전자가 직접 작동스위치버튼을 눌러 작동되는 램프(실내등, 비상등)와, 브레이크페달을 밟았을 때 작동되는 램프(브레이크등) 등 차량에 각종램프에 메인램프(12)와 보조램프(14)를 일체로 형성한 2중램프(10)를 구비하고, 배터리전원에 의해 메인램프(12)가 점등되도록 접속된다.1 is a circuit diagram showing the configuration of a vehicle dual lamp lighting device having an auxiliary lamp according to the present invention. 1, when the vehicle is started, the lamp (headlamp) operated by the light switch contact point, the driver directly presses the operation switch button (indoor light, emergency light) and when the brake pedal is pressed The vehicle is provided with a double lamp 10 in which a main lamp 12 and an auxiliary lamp 14 are integrally formed in various lamps in a vehicle such as an activated lamp (brake light), and the main lamp 12 is turned on by battery power. To be connected.

상기 배터리전원에 의해 점소등되는 메인램프(12)의 점등된 상태를 감지하여 보조램프를 점소등시키는 보조램프구동부(20)로, 메인램프(12)의 점등된 상태를 감지하기 위해 메인램프(12)의 내부에 설치되고, 메인램프(12)가 점등되면 배터리전원이 광감지소자(22)로 바이패스시키도록 포토트랜지스터 또는 포토다이오드 및 CDS 등으로 배터리전원을 바이패스시키게 된다. 반대로, 메인램프(12)가 소등되면 광감지소자(22)로 바이패스되는 배터리전원은 차단된다. 상기 메인램프(12)의 광에 의해 바이패스된 신호는 부정논리회로(24)에 입력된다.The auxiliary lamp driver 20 detects the lit state of the main lamp 12 which is turned on by the battery power and turns off the auxiliary lamp. The main lamp 12 detects the lit state of the main lamp 12. When the main lamp 12 is turned on and the main lamp 12 is turned on, the battery power is bypassed by a phototransistor or a photodiode and a CDS such that the battery power is bypassed to the photosensitive device 22. On the contrary, when the main lamp 12 is turned off, the battery power bypassed to the photosensitive device 22 is cut off. The signal bypassed by the light of the main lamp 12 is input to the negative logic circuit 24.

상기 부정논리회로(24)는 광감지소자(22)에서 감지된 신호를 반전시켜 보조램프(14)를 점소등시키게 된다. 즉, 상기 메인램프(12)의 광이 감지되면, 감지된 신호는 부정논리회로(24)의 논리신호에 의해 로우신호가 출력되어 보조램프(14)를 소등시키게 된다. 반대로, 메인램프(12)의 소등되어 광이 감지되지 않으면, 감지된 신호는 부정논리회로(24)의 논리신호에 의해 하이신호가 출력되므로 보조램프(14)를 점등시키게 된다.The negative logic circuit 24 inverts the signal detected by the photosensitive device 22 to turn off the auxiliary lamp 14. That is, when the light of the main lamp 12 is detected, the sensed signal is outputted by the logic signal of the negative logic circuit 24 to turn off the auxiliary lamp 14. On the contrary, if light is not detected because the main lamp 12 is turned off, the detected signal turns on the auxiliary lamp 14 because a high signal is outputted by the logic signal of the negative logic circuit 24.

또한, 램프이상유무표시부(30)는 메인램프(12)의 이상유무에 따라 메인램프(12)로 입력되는 배터리전원은 램프이상유무표시부(30)로 입력된다. 즉, 메인램프(12)가 점등되면 메인램프(12)로 입력되는 배터리전원은 메인램프(12)로 바이패스되므로, 램프이상유무표시부(30)의 트랜지스터(32)에는 로우신호가 입력되어 트랜지스터(32)는 턴오프된다. 반대로, 메인램프(12)가 소등되면 메인램프(12)로 바이패스되는 전원은 차단되고, 차단된 전원은 트랜지스터(32)의 베이스로 입력되며, 입력된 신호에 의해 트랜지스터(32)의 콜렉터에 입력된 배터리전원은 트랜지스터(32)로 통전되어 표시램프(34)를 점등시키게 되므로 운전자의 육안으로 메인램프(12)의 이상유무를 표시하게 된다.In addition, the lamp abnormality display unit 30 is the battery power input to the main lamp 12 in accordance with the abnormality of the main lamp 12 is input to the lamp abnormality display unit 30. That is, when the main lamp 12 is turned on, since the battery power input to the main lamp 12 is bypassed to the main lamp 12, a low signal is inputted to the transistor 32 of the lamp abnormality display unit 30, thereby providing a transistor. 32 is turned off. On the contrary, when the main lamp 12 is turned off, the power bypassed to the main lamp 12 is cut off, and the blocked power is input to the base of the transistor 32, and the input signal is applied to the collector of the transistor 32. Since the input battery power is supplied to the transistor 32 to turn on the display lamp 34, the driver's naked eye displays the abnormality of the main lamp 12.

상기와 같은, 표시부(20)의 트랜지스터(22)와 보조램프구동부(40)의 트랜지스터(42)는 차량의 구비된 램프의 수에 따라 변화되고, 각종램프로 입력되는 신호에 의해 메인램프(12)의 이상유무를 감지하게 되며, 감지된 신호로 메인램프(12)와 일체로 형성된 2중램프(10)의 보조램프(14)를 점등시키게 되는 것이다.As described above, the transistor 22 of the display unit 20 and the transistor 42 of the auxiliary lamp driver 40 change according to the number of lamps provided in the vehicle, and the main lamp 12 is changed by signals input to various lamps. ) Is detected, and the auxiliary lamp 14 of the double lamp 10 formed integrally with the main lamp 12 is turned on by the detected signal.

이와 같은 구성을 갖는 본 고안의 작용을 차량에 구비된 램프에 적용하여 설명하면 다음과 같다.When explaining the operation of the present invention having such a configuration applied to the lamp provided in the vehicle as follows.

차량에 구비된 램프를 점등하기 위해 스위치를 누르게 되면, 상기 스위치접점으로 통전된 배터리전원은 램프를 점등시키게 된다. 상기 램프에 메인램프(12)와 보조램프(14)를 일체로 형성한 2중램프(10)의 메인램프(12)의 점소등된 상태를 감지하도록 메인램프(12)로 입력되는 배터리전원에 의해 보조램프를 점등시키는 보조램프구동부(20)와 램프이상유무표시부(30)로 메인램프의 이상유무를 표시하게 되는 것이다.When the switch is pressed to turn on a lamp provided in the vehicle, the battery power supplied to the switch contact turns on the lamp. On the battery power input to the main lamp 12 to detect the turned off state of the main lamp 12 of the dual lamp 10 in which the main lamp 12 and the auxiliary lamp 14 are integrally formed in the lamp. As a result, the auxiliary lamp driving unit 20 and the lamp abnormality display unit 30 which turn on the auxiliary lamp display abnormality of the main lamp.

상기 보조램프구동부(20)는 메인램프(12)의 광을 감지하게 된다. 즉, 메인램프(12)가 점등되면 광감지소자(22)로 입력된 신호는 광감지소자(22)로 바이패스되고, 바이패스된 배터리전원은 부정논리회로(24)의 논리신호에 의해 반전되어 보조램프(14)는 소등된다. 반대로, 메인램프(12)가 소등되면 광감지소자(22)로 바이패스되는 배터리전원은 차단되고, 부정논리회로(22)의 논리신호에 의해 입력된 신호는 반전되어 보조램프(14)를 점등시키게 된다. 따라서, 광감지소자(22)에서 감지되는 신호에 의해 메인램프(12)와 일체로 형성된 보조램프(14)가 점등된다.The auxiliary lamp driver 20 detects light of the main lamp 12. That is, when the main lamp 12 is turned on, the signal input to the photosensitive device 22 is bypassed to the photosensitive device 22, and the bypassed battery power is inverted by the logic signal of the negative logic circuit 24. The auxiliary lamp 14 is turned off. On the contrary, when the main lamp 12 is turned off, the battery power bypassed to the photosensitive device 22 is cut off, and the signal inputted by the logic signal of the negative logic circuit 22 is inverted to light up the auxiliary lamp 14. Let's go. Therefore, the auxiliary lamp 14 formed integrally with the main lamp 12 is turned on by the signal detected by the light sensing element 22.

또한, 2중램프(10)의 메인램프의 제 1램프(12)가 소등되면, 제 1램프(12)로 입력된 전류량은 감소되고, 제 2램프(12')로 입력되는 전류량은 증가하게 된다. 따라서, 제 2램프(12')로 증가된 전류량에 의해 램프이상유무를 표시하도록 된 램프이상유무표시부(20)의 트랜지스터(22')의 바이어스전류가 증가되고, 상기 트랜지스터(22')는 턴온되고, 콜렉터에 공급된 배터리전원은 트랜지스터(22')로 통전되어 표시램프의 제 1표시램프(24)가 점등되어 메인램프의 제 1램프(12)의 이상유무를 표시하게 된다.In addition, when the first lamp 12 of the main lamp of the double lamp 10 is turned off, the amount of current input to the first lamp 12 is decreased, and the amount of current input to the second lamp 12 'is increased. do. Accordingly, the bias current of the transistor 22 'of the lamp abnormality display part 20 is increased by the amount of current increased by the second lamp 12', and the transistor 22 'is turned on. The battery power supplied to the collector is energized to the transistor 22 'so that the first display lamp 24 of the display lamp is turned on to indicate whether there is an abnormality of the first lamp 12 of the main lamp.

반대로, 2중램프(10)의 제 2램프(12')가 소등되면, 제 2램프(12')로 입력된 전류량은 감소되고, 제 1램프(12)로 입력되는 전류량은 증가된다. 트랜지스터(22)는 턴온되며, 콜렉터에 공급된 배터리전원은 트랜지스터(22)로 통전되어 메인램프의 제 2램프(12')의 이상유무를 표시하게 된다.On the contrary, when the second lamp 12 'of the double lamp 10 is turned off, the amount of current input to the second lamp 12' is decreased, and the amount of current input to the first lamp 12 is increased. The transistor 22 is turned on, and the battery power supplied to the collector is energized to the transistor 22 to indicate an abnormality of the second lamp 12 'of the main lamp.
