Description

차량용 램프{Lamp for vehicle}Lamp for vehicle

본 발명은 차량용 램프에 관한 것으로서, 더욱 상세하게는 운전자의 시인성 증대를 위해 차량의 램프류에 적용하는 나이트 비전 시스템에서 적외선을 전방으로 조사하는 광섬유와 IR 필름 조합 형태의 적외선 램프를 포함하는 차량용 램프에 관한 것이다. The present invention relates to a vehicle lamp, and more particularly to a vehicle lamp including an infrared lamp in the form of a combination of optical fiber and IR film to irradiate the infrared in the night vision system applied to the lamps of the vehicle to increase the visibility of the driver. It is about.

일반적으로 야간에 운전자의 양호한 시야 확보를 위해 사용되는 나이트 비전 시스템(Night vision system)은 적외선 램프가 차량의 전방으로 적외선(infrared light)을 투사하고, 차량에 설치된 카메라가 그 반사된 이미지를 기록하는 방식으로 이루어져 있다. Night vision systems, which are typically used to ensure good visibility for drivers at night, are characterized by the fact that infrared lamps emit infrared light in front of the vehicle, and cameras installed in the vehicle record the reflected image. It consists of the way.

카메라에 의해 기록된 이미지는 차량의 운전자가 쉽게 볼 수 있는 위치에 설치된 디스플레이 화면에 나타남으로써, 운전자가 차량 전방에 위치한 물체를 용이하게 확인할 수 있다.The image recorded by the camera appears on a display screen installed at a position easily visible to the driver of the vehicle, so that the driver can easily check the object located in front of the vehicle.

예를 들면, 나이트 비전 시스템은 눈부심이 없는 적외선을 조사하고, 도로 장애물에 반사되어 돌아오는 광선을 적외선 카메라로 감지하여 영상신호로 변환시킨 후, 이를 운전자가 볼 수 있도록 디스플레이시킴으로써, 야간 주행시 운전자 시인성을 높일 수 있다For example, the night vision system irradiates the infrared without glare, detects the rays reflected by the road obstacles by using an infrared camera, converts them into image signals, and displays them for the driver to see. Can increase

하이빔(Hi-beam) 램프와는 별도로 적외선 램프가 구비되는 경우도 있으나, 비용절감 및 레이아웃의 문제 등으로 전조등과 일체로 형성되는 하이빔/적외선 일체형 램프가 사용되는 것이 일반적이다.In some cases, an infrared lamp is provided separately from a high-beam lamp, but a high beam / infrared lamp integrated with the headlamp is generally used due to cost reduction and layout problems.

하이빔/적외선 일체형 램프는 일 예로 하이빔 벌브(Hi-beam bulb)를 덮을 수 있도록 램프 하우징 내에 설치되는 적외선 투과 필터를 구비한다.The high beam / infrared integrated lamp has, for example, an infrared transmission filter installed in the lamp housing so as to cover the hi-beam bulb.

하이빔 램프로 사용되는 경우 적외선 투과 필터가 하이빔 벌브를 덮지 않도록 작동되며, 적외선 램프로 사용되는 경우 적외선 투과 필터가 하이빔 벌브를 덮도록 작동된다.When used as a high beam lamp, the infrared transmission filter is operated so as not to cover the high beam bulb, and when used as an infrared lamp, the infrared transmission filter is operated to cover the high beam bulb.

이와 같은 적외선 투과 필터의 작동은 별도로 구비된 액추에이터에 의해 이루어진다.Operation of such an infrared transmission filter is performed by an actuator provided separately.

현재 적외선 램프가 적용되고 있는 차량용 램프류는 ①프로젝션 쉴드에 IR 코팅을 하고 솔레노이드를 이용하여 쉴드를 구동시키는 방식(하이빔&포지션+적외선 램프), ②MFR 벌브 쉴드 내부에 별도 IR 쉴드를 적용하고 솔레노이드를 이용하여 IR 쉴드를 구동시키는 방식(하이빔&포지션+적외선 램프), ③프로젝션 쉴드에 IR 코팅하여 적외선 램프 기능만 수행하는 방식(적외선 램프) 등이 있다. Vehicle lamps that are currently applied with infrared lamps are: ① IR coating on the projection shield and a solenoid to drive the shield (high beam & position + infrared lamps). ② Separate IR shield inside the MFR bulb shield and use solenoids. To operate the IR shield (high beam & position + infrared lamp), and ③ to perform the IR lamp function by infrared coating on the projection shield (infrared lamp).

그러나, 위의 ①번 및 ②번과 같은 램프의 경우 프로젝션 모듈 1개가 적외선 램프의 역할을 하기 때문에 변환빔과 주행빔을 각각 구성하기에는 램프의 공간이 부족하여 디자인의 제약이 따른다. However, in the case of the lamps such as ① and ② above, since one projection module plays the role of an infrared lamp, the space of the lamp is insufficient to constitute the conversion beam and the traveling beam, and thus design constraints occur.

또한, 솔레노이드를 이용하여 변환빔과 주행빔의 기능을 동시에 가질 수 있게 하면 램프의 구조가 복잡해짐으로 인해 내구력 저하 및 원가상승을 동반한다. In addition, when the solenoid is used to have the function of the conversion beam and the traveling beam at the same time, the structure of the lamp is complicated, thereby bringing durability and cost increase.

또한, 위의 ②번과 같은 경우 원형 타입의 코팅이 수반되는 등 IR 코팅에 어려움이 있고, 위의 ③번과 같은 경우 한가지 기능만 수행하기 때문에 하이빔과 적외선 램프를 함께 갖추어야 하는 등 레이아웃 설계 측면과 원가 측면에서 불리한 점이 있다. In addition, in the case of ② above, there is a difficulty in IR coating, which involves a circular coating, and in the case of ③ above, only one function is required. There are disadvantages in terms of cost.

따라서, 본 발명은 이와 같은 점을 감안하여 안출한 것으로서, 일반 변환빔 기능은 물론 광섬유와 IR 필름을 조합하여 적외선 램프의 기능을 수행할 수 있는 새로운 형태의 복합 램프를 구현함으로써, 하나의 프로젝션 모듈을 이용하여 변환빔과 적외선 램프 기능을 만족시킬 수 있으며, 이에 따라 램프의 내구성능 향상 및 원가 절감을 도모할 수 있는 차량용 램프를 제공하는데 그 목적이 있다. Accordingly, the present invention has been made in view of the above, by implementing a new type of composite lamp capable of performing the function of the infrared lamp by combining the optical fiber and the IR film as well as the general conversion beam function, one projection module It is possible to satisfy the function of the conversion beam and the infrared lamp by using, and to provide a vehicle lamp that can improve the durability and cost reduction of the lamp accordingly.

상기 목적을 달성하기 위하여 본 발명에서 제공하는 차량용 램프는 전면의 렌즈, 내부의 전구 및 리플렉터, 이것들을 수용하는 하우징 등을 포함하는 한편, 상기 리플렉터의 일측에 IR 필름이 설치되고, 이 IR 필름으로부터 램프 전면까지 길게 연장되는 형태의 광섬유가 구비되어, 일반 변환빔 기능과 적외선 램프 기능을 겸할 수 있도록 된 것을 특징으로 한다. In order to achieve the above object, a vehicle lamp provided by the present invention includes a front lens, an inner bulb and a reflector, a housing for accommodating these, and an IR film is provided on one side of the reflector, The optical fiber of the form extending to the front of the lamp is provided, it is characterized in that it can serve as a general conversion beam function and infrared lamp function.

여기서, 상기 광섬유의 경우 다수 개가 하우징의 주위를 따라 원형으로 배치되는 형태나, 다수 개가 램프의 하단부 또는 상단부를 따라 직선으로 배치되는 형태 등으로 설치하여 사용하는 것이 램프의 첨단 이미지를 구현하는 측면에서 바람직하다. Here, in the case of the optical fiber is installed in the form of a plurality is arranged in a circle along the periphery of the housing, or in the form of a plurality of dogs are arranged in a straight line along the lower end or the upper end of the lamp in terms of implementing the state-of-the-art image of the lamp desirable.

본 발명은 광섬유와 IR 필름을 조합한 적외선 램프를 갖춘 차량용 램프를 제공함으로써, 프로젝션 모듈 1개를 이용하여 변환빔 기능과 적외선 램프 기능을 동시에 구현할 수 있으며, 따라서 솔레노이드와 같은 전기적인 장치가 필요없기 때문에 내구성능을 높일 수 있고, 비용면에서도 경제적인 이점이 있으며, 램프 제작시 디자인 제약없이 설계 자유도를 높일 수 있는 효과, 즉 차량 디자인 자유도를 증가시킬 수 있는 효과가 있다. The present invention provides a vehicle lamp having an infrared lamp that combines an optical fiber and an IR film, so that a conversion beam function and an infrared lamp function can be simultaneously implemented using one projection module, thus eliminating the need for an electrical device such as a solenoid. Therefore, the durability can be increased, and there is an economic advantage in terms of cost, and there is an effect that can increase the design freedom without design constraints, that is, increase the design freedom of the vehicle.

이하, 첨부한 도면을 참조하여 본 발명을 상세히 설명하면 다음과 같다.Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

도 1과 도 2는 본 발명의 일 실시예에 따른 차량용 램프를 나타내는 사시도와 단면도이다. 1 and 2 are a perspective view and a cross-sectional view showing a vehicle lamp according to an embodiment of the present invention.

도 1과 도 2에 도시한 바와 같이, 상기 차량용 램프는 일반 변환빔 기능을 가짐은 물론 IR 필터에 의해 발생된 적외선을 광섬유(Plastic optical fiber)를 통해 전방으로 조사하는 기능을 가지는 한편, 광섬유를 이용하여 변환빔과 적외선 램프 기능을 하나의 프로젝션 모듈에서 가능하게 하는 구조는 갖는다. As shown in FIG. 1 and FIG. 2, the vehicle lamp not only has a general conversion beam function, but also has a function of irradiating the infrared rays generated by the IR filter to the front through the optical fiber. Has a structure that enables the conversion beam and infrared lamp functions in one projection module.

이를 위하여, 상기 램프는 일반 변환빔 기능을 수행할 수 있는 보통의 램프 구조, 예를 들면 램프 전면에 배치되는 비구면의 렌즈(10), 빛의 발원 및 반사를 위해 램프 내부에 배치되는 전구(11) 및 리플렉터(12), 상기 전구(11) 및 리플렉터(12)를 수용하면서 앞쪽은 렌즈(10)로 마감되는 하우징(13) 등을 포함하는 구조를 갖는다. To this end, the lamp has a conventional lamp structure capable of performing a normal conversion beam function, for example an aspheric lens 10 disposed in front of the lamp, and a light bulb 11 arranged inside the lamp for the emission and reflection of light. ) And the reflector 12, the bulb 11 and the reflector 12, the front side has a structure including a housing 13 and the like finished with a lens (10).

이에 따라, 전구(11)에서 발한 빛은 리플렉터(12)에 반사되어 렌즈(10)를 통해 전방으로 조사되고, 이때의 조사되는 가시광선은 일반 변환빔으로서의 역할을 하게 된다. Accordingly, the light emitted from the light bulb 11 is reflected by the reflector 12 and irradiated forward through the lens 10, and the visible light emitted at this time serves as a general conversion beam.

특히, 상기 램프는 적외선 램프의 기능을 겸비하게 되는데, 이를 위하여 리플렉터(12)의 일측, 예를 들면 후면부 일측에는 IR 필터 역할을 하는 IR 필름(14)이 설치되고, 이렇게 설치되는 IR 필터(14)와 램프 전면 사이에는 광섬유(15)가 길게 연장되는 형태로 연결 설치된다. In particular, the lamp is to combine the function of the infrared lamp, for this purpose, one side of the reflector 12, for example, one side of the rear portion is provided with an IR film 14 that serves as an IR filter, the IR filter 14 is installed in this way ) And the front surface of the lamp is connected to the optical fiber 15 in the form of a long extension.

즉, 광섬유(15)의 한쪽 끝은 리플렉터(12)측의 IR 필름(14)에 맞닿아서 전구(11)에서 나오는 빛이 IR 필름(14)을 거쳐 적외선으로 바뀐 후 광섬유를 통해서 나오게 되고, 이렇게 유도된 빛은 광섬유(15)의 다른 한쪽 끝을 통해 최종적으로 차량 전방으로 조사될 수 있다. That is, one end of the optical fiber 15 is in contact with the IR film 14 of the reflector 12 side, the light from the bulb 11 is converted to infrared light through the IR film 14 and then exits through the optical fiber, The light thus induced may finally be irradiated to the front of the vehicle through the other end of the optical fiber 15.

이때, 상기 IR 필름(14)의 경우 리플렉터(12)에 홀을 형성하고, 이 홀을 차단하는 형태로 부착 등의 방법으로 설치할 수 있거나, 또는 리플렉터 성형시 일체 성형시키는 방법 등으로 설치할 수 있다. In this case, in the case of the IR film 14, a hole may be formed in the reflector 12, and the hole may be installed by attaching or the like to block the hole, or may be installed by integral molding during reflector molding.

또한, 상기 램프의 전면까지 연장된 광섬유(15)의 선단부는 하우징(13)에 형성되어 있는 광섬유 지지대(17)를 이용하여 고정시킬 수 있다. In addition, the front end portion of the optical fiber 15 extending to the front of the lamp can be fixed using the optical fiber support 17 formed in the housing (13).

여기서, 상기 광섬유(15)는 내부의 코어를 클래드가 감싸고 있는 형태로서, 대략 50∼3,000㎛ 정도의 직경과 2θ의 최대 입사각을 갖는 것을 적용할 수 있다. Here, the optical fiber 15 is a form in which a clad is wrapped around an inner core, and may have a diameter of about 50 to 3,000 μm and a maximum incidence angle of 2θ.

또한, 상기 광섬유(15)의 선단부에는 소형 렌즈(16)가 부착되어 있으며, 이에 따라 광섬유(15)를 따라 유도된 적외선은 소형 렌즈(16)를 거쳐 최종 조사될 수 있다. In addition, a small lens 16 is attached to the distal end of the optical fiber 15, and thus infrared rays guided along the optical fiber 15 may be finally irradiated through the small lens 16.

이러한 광섬유(15)는 다수 개가 구비되어 여러 다양한 배치 형태로 차량 램프에 적용할 수 있는데, 예를 들면 하우징(13)의 주위를 따라 원형으로 배치되는 형태(도 3), 또는 하우징(13)의 윗쪽이나 아래쪽에서 하우징과 나란한 상태에서 직선으로 배치되는 형태(도 4) 등으로 차량 램프에 적용할 수 있다. The optical fiber 15 is provided with a plurality of it can be applied to the vehicle lamp in a variety of different arrangements, for example, the shape is arranged in a circle along the periphery of the housing 13 (Fig. 3), or of the housing 13 It can be applied to a vehicle lamp in the form of being arranged in a straight line in the state parallel to the housing from above or below (Fig. 4).

따라서, 이와 같은 광섬유를 이용한 적외선 램프 기능을 갖는 차량용 램프의 작동 상태를 살펴보면 다음과 같다. Therefore, the operation state of the vehicle lamp having the infrared lamp function using such an optical fiber is as follows.

도 5는 본 발명의 일 실시예에 따른 차량용 램프의 작동 상태를 나타내는 단면도이다. 5 is a cross-sectional view showing an operating state of a vehicle lamp according to an embodiment of the present invention.

도 5에 도시한 바와 같이, 램프 작동시 제1초점인 전구(11)에서 방사된 가시광선은 리플렉터(12)에 반사되어 제2초점을 지나 비구면의 렌즈(10)를 통해 전방으로 조사된다. As shown in FIG. 5, visible light emitted from the light bulb 11, which is the first focal point, when the lamp is operated, is reflected by the reflector 12 and passes forward through the aspherical lens 10 through the second focal point.

이때의 조사되는 광선은 가시광선으로서 변환빔의 기능을 한다. The irradiated light at this time functions as a converted beam as visible light.

한편, 제1초점에서 나온 가시광선 중의 일부는 리플렉터(12)와 광섬유(15)가 맞닿은 부분의 리플렉터 홀을 채우고 있는 IR 필름(14)을 지나면서 필터링되고, 이렇게 필터링된 적외선은 광섬유(15)를 통해 유도되어 광섬유 선단부에 부착되어 있는 소형 렌즈(16)를 통하여 전방으로 조사된다. Meanwhile, some of the visible light emitted from the first focus is filtered through the IR film 14 which fills the reflector hole in the part where the reflector 12 and the optical fiber 15 come into contact with each other. It is guided through the small lens 16 attached to the tip of the optical fiber is irradiated forward.

이때, IR 필름(14)에서 필터링되지 않고 반사된 빛은 가시광선과 마찬가지로 비구면의 렌즈(10)를 통해 전방으로 조사된다. At this time, the unfiltered light reflected by the IR film 14 is irradiated forward through the lens 10 of the aspherical surface as in the visible light.

이와 같이, 본 발명에서 제공하는 램프의 경우 프로젝션 모듈 1개를 이용하 여 변환빔과 적외선 램프의 기능을 만족시킬 수 있고, 종전의 솔레노이드 등과 같은 전기적인 장치가 필요없기 때문에 내구성능을 높일 수 있다. As described above, the lamp provided by the present invention can satisfy the functions of the conversion beam and the infrared lamp by using one projection module, and can increase the durability since an electric device such as a conventional solenoid is not required.

또한, 본 발명에서 제공하는 차량용 램프, 예를 들면 광섬유를 이용한 적외선 램프 기능을 갖는 차량용 램프는 헤드 램프 뿐만 아니라, 테일 램프나 스톱 램프 등 여러 종류의 차량용 램프류에 폭넓게 적용할 수 있다. In addition, a vehicle lamp provided in the present invention, for example, a vehicle lamp having an infrared lamp function using an optical fiber can be widely applied to various kinds of vehicle lamps such as tail lamps and stop lamps as well as head lamps.
