Description

차량용 헤드램프의 제습 방법{Dehumidification method of vehicle head lamp}Dehumidification method of vehicle head lamp

본 발명은 차량용 헤드램프의 제습 방법에 관한 것으로서, 특히 차량의 헤드램프에서 외부와 내부의 온도차이로 인해 발생하는 습기를 제거하기 위한 차량용 헤드램프의 제습 방법에 관한 것이다.
The present invention relates to a method for dehumidifying a headlamp for a vehicle, and more particularly, to a method for dehumidifying a headlamp for a vehicle for removing moisture caused by a temperature difference between the outside and the inside of the vehicle headlamp.

일반적으로 차량의 헤드램프는 야간 주행 시 운전자의 야간 시야 확보를 위한 것으로, 운전자의 제어에 의해 헤드 벌브(bulb)로부터 조사(照射)된 빛을 운전자의 시야 확보를 위해 빛이 잘 투과되도록 헤드램프의 빛 투과부(헤드램프의 렌즈)를 청결하게 유지시켜야 한다. In general, the headlamp of the vehicle is to secure the driver's night vision when driving at night, and the headlamp is configured to transmit the light radiated from the head bulb under the driver's control to ensure the driver's vision. Keep the light transmission part of the headlamp lens clean.

또한, 최근에는 차량의 디자인 측면에서도 헤드램프의 형상이 매우 중요한 위치를 차지하고 있으므로, 상기 헤드램프의 주변 기기들이 차량 전체의 디자인에 영향을 미치지 않도록 하는 것이 중요하게 되었다.In addition, recently, since the shape of the headlamp occupies a very important position in terms of the design of the vehicle, it has become important that the peripheral devices of the headlamp do not affect the design of the entire vehicle.

따라서, 외부에 항상 노출되어 있는 헤드램프의 렌즈 등에 램프 내외의 온도 차이 등의 주변 환경에 의해 습기나 서리가 발생하므로, 이를 방지하기 위해 제습 장치가 구비되는 경우가 있다.Therefore, since moisture or frost is generated by the surrounding environment such as the temperature difference between the inside and outside of the lamp and the like of the lens of the headlamp which is always exposed to the outside, a dehumidifying device may be provided to prevent this.

종래의 차량용 헤드램프는 제습을 위해서, 램프 내에 환기 장치를 구비하여 램프의 제습을 하는 경우가 있으나, 이는 구조가 복잡하고, 상기 헤드램프의 제습을 위해 환기 장치를 별도로 구비해야 하므로, 조립 공수가 늘어나며, 비용면에서도 불리함을 가지고 있다. Conventional vehicle headlamps have a ventilation device in the lamp to dehumidify the lamp for dehumidification, but this is complicated in structure and requires a separate ventilation device for dehumidifying the headlamp. It also has disadvantages in terms of cost.

한편, 헤드램프의 제습을 위해 램프 내에 방습제(防濕劑)를 구비하는 경우가 있는데, 여기서 사용되는 방습제는 화학 물질로 구성된 실리카겔(silica gel)의 경우, 규산(硅酸) 나트륨을 강산(强酸)으로 분해 처리한 화학적 분자 구조이므로 장시간의 구조 변경이 일어난 후에 분해되기 때문에 환경에 해를 끼치게 된다. On the other hand, there is a case in which a desiccant is provided in the lamp for dehumidifying the headlamp. In the case of a silica gel composed of a chemical substance, sodium silicate is used as a strong acid. Because it is a chemical molecular structure that has been decomposed into), it is decomposed after a long time structural change, thus causing damage to the environment.

또한, 염화칼슘(CaCl2)의 조해성(潮解性, deliquescence : 고체가 대기 속에서 습기를 빨아들여 녹는 성질)을 이용한 방습제의 경우는, 이 방습제의 중량의 3배(300%)까지 지나치게 많이 수분을 흡습(吸濕)하므로 수용액의 용출(湧出) 현상이 일어나, 사용 중에 분진(粉塵)이 비산(飛散)될 우려가 있으며, 상기 방습제가 분진을 흡습하게 되면 형체가 파괴되면서 수분이 누출되어 제품에 치명적인 손상을 줄 수도 있다는 문제점이 있다. In addition, in the case of the desiccant using calcium chloride (CaCl2) deliquessibility (deliquescence: the property that the solid absorbs and melts moisture in the air), the moisture absorbent absorbs excessively up to three times the weight of the desiccant (300%). (吸濕) As a result of the elution of the aqueous solution, dust may be scattered during use, and if the moisture absorbent absorbs the dust, the body is destroyed and the water leaks, which is fatal to the product. There is a problem that it may damage.

게다가, 이와 같은 종래의 헤드램프용 방습제는 수분을 흡습만 하도록 한 것으로, 일정 기간이 지난 후에는 그 수명이 다하여 교환이 필요하므로 상품성을 저하시키는 문제점도 있었다.
In addition, such a conventional headlamp desiccant only absorbs moisture, and after a certain period of time, its lifespan expires and replacement is required.

본 발명은 상기의 문제점을 해소하기 위한 차량용 헤드램프의 제습 방법에 관한 것으로서, 특히 차량의 헤드램프에서 외부와 내부의 온도차이로 인해 발생하는 습기를 제거하기 위한 것을 목적으로 한다.
The present invention relates to a method for dehumidifying a headlamp for a vehicle for solving the above problems, and particularly, to remove moisture generated due to a temperature difference between the outside and the inside of a headlamp of a vehicle.

이하 본 발명의 차량용 헤드램프의 제습 방법에 대한 각 구성요소를 첨부한 도면을 참조하여 하나씩 살펴보면 다음과 같다.Hereinafter, each component of the method for dehumidifying a headlamp for a vehicle according to the present invention will be described with reference to the accompanying drawings.

우선 본 발명은 도 1에 도시된 바와 같이, 라이트(1)를 포함하는 헤드램프 내부에 광원의 난반사를 검출하는 포토다이오드 센서(2)와, 송풍을 위한 팬(4)과, 상기 팬(4) 구동을 위한 컨트롤러(2)와, 제습을 위한 폴리테트라 플루오르에틸렌(5)이 구비되는 것을 기본으로 한다.First, as shown in FIG. 1, the present invention provides a photodiode sensor 2 for detecting diffuse reflection of a light source inside a headlamp including a light 1, a fan 4 for blowing air, and the fan 4. It is basically provided with a controller 2 for driving and a polytetrafluoroethylene 5 for dehumidification.

도 1 및 도 2에 도시된 바와 같이, 난반사측정단계(S10)는 차량의 헤드램프에 장착된 포토다이오드 센서(2)를 통해 라이트(1)로부터 발광되는 광원의 난반사를 측정하는 단계이다.As shown in FIG. 1 and FIG. 2, the diffuse reflection measuring step S10 is a step of measuring diffuse reflection of the light source emitted from the light 1 through the photodiode sensor 2 mounted on the headlamp of the vehicle.

여기서, 난반사를 측정하는 이유는 발광된 광원이 헤드램프의 렌즈측으로 조사되는 상태에서 상기 렌즈에 습기가 맺혀지게 되면 광원이 일정한 각도로 반사되는 것이 아닌 습기의 물방울에 의해 난반사가 일어나기 때문에 습기 발생여부를 판단하기 위해 난반사를 측정하게 되는 것이다.Here, the reason for measuring the diffuse reflection is that if moisture is condensed on the lens while the emitted light source is irradiated toward the lens side of the headlamp, the light source is not reflected at a predetermined angle, but diffused reflection is caused by water droplets of moisture. It is to measure the diffuse reflection to determine.

난반사비교판단단계(S20)는 상기 난반사측정단계(S10)에서 측정된 난반사 결과값과 최초에 설정된 기준값을 상호 비교하는 단계이다.The diffuse reflection comparison determination step (S20) is a step of comparing the diffuse reflection result value measured in the diffuse reflection measurement step (S10) with a reference value initially set.

이때, 상기 난반사비교판단단계(S20)에서 측정된 난반사 결과값과 기준값 비교 시 상기 난반사 결과값이 기준값을 초과하는 경우에는 상술한 바와 같이 동력구동단계(S30)로 진행되며, 상기 난반사 결과값이 기준값 이하인 경우 초기단계로 이동하게 되는 것이 바람직하다.At this time, when the diffuse reflection result value exceeds the reference value when the diffuse reflection result value measured in the diffuse reflection comparison step (S20) is compared with the reference value, the power reflection step S30 is performed as described above, and the diffuse reflection result value is If it is less than the reference value it is preferable to move to the initial stage.

습기제거단계(S40)는 상기 동력구동단계(S30)에서 동력 구동 시 상기 컨트롤러(3)와 연동되는 팬(4)을 작동시켜 상기 헤드램프 내부를 제습시키게 되는 단계이다.Dehumidifying step (S40) is a step to dehumidify the inside of the headlamp by operating the fan (4) linked with the controller (3) when the power drive in the power drive step (S30).
