Description
본 발명은 헤드램프의 배광장치에 관한 것으로서, 더욱 상세하게는 헤드램프의 벌브에서 발산된 빔을 반사하는 반사판을 상하로 나누어 상측은 파라볼라형 반사판으로, 하측은 이립티컬형 반사판으로 형성하여 배광성능을 향상시킬 수 있도록 하는 헤드램프의 배광장치에 관한 것이다.The present invention relates to a light distribution device of a head lamp, and more particularly, the upper side is formed by a parabolic reflector, and the lower side is formed by an inverted reflective plate by dividing a reflector reflecting a beam emitted from the bulb of the headlamp. It relates to a light distribution device of a head lamp to improve the.
종래의 헤드램프는 도 1에 도시한 것처럼, 차량에 고정 설치되는 하우징(1) 내에는 이립티컬형 반사판(2;Elliptical Type Reflector)이 내입되고, 이 반사판(2)의 후방에는 전방으로 빔을 조사할 수 있도록 이루어진 필라멘트를 갖는 벌브(3)가 설치되며, 이 반사판(2)의 전면에는 이격관(5)에 의해 소정거리 이격된 비구면 렌즈(8)가 배치되는 한편, 이 이격관(5)의 내측 하단에는 플레이트(6)가 입설되며, 하우징(1)의 전후방에는 렌즈(7)와 더스트 커버(4:Dust Cover)가 각각 결합되어있다.In the conventional headlamp, as shown in FIG. 1, an elliptical type reflector 2 is embedded in a housing 1 fixed to a vehicle, and a beam is forwarded to the rear of the reflector 2. A bulb 3 having a filament configured to be irradiated is provided, and an aspherical lens 8 spaced a predetermined distance by the spacer 5 is disposed on the front surface of the reflecting plate 2, while the spacer 5 Plate 6 is placed in the inner lower end of the, and the lens 7 and the dust cover (4: Dust Cover) is coupled to the front and rear of the housing (1), respectively.
이와같이 구성된 헤드램프의 동작을 설명한다.The operation of the headlamp configured as described above will be described.
다기능레버의 조작으로 벌브(3)가 점등하게 되면, 벌브(3)에서 발산된 빔은 방사형으로 발산되어 반사판(2)에 닿게 되고, 이어서 이립티컬형 반사판(2)에 의해 도 1에서와 같이 반사되게 된다. 그리고 반사판(2)에 의해 반사되는 빔은 비구면 렌즈(8)를 통과하면서 수평방향의 빔으로 변환되어 렌즈(7)를 통해 외부로 조사되게 된다.When the bulb 3 is turned on by the operation of the multifunction lever, the beam emitted from the bulb 3 is radiated radially and touches the reflecting plate 2, and then, as shown in FIG. 1, by the elliptical reflecting plate 2. Will be reflected. The beam reflected by the reflector 2 is converted into a horizontal beam while passing through the aspherical lens 8 and irradiated to the outside through the lens 7.
특히, 이격관(5)의 내측 하단에 입설된 플레이트(6)가 반사판(2)에 의해 반사된 빔의 일부를 차단함으로써, 헤드램프의 조사각도를 조절할 수 있는 것이다.In particular, the plate 6 placed on the inner lower end of the spacer tube 5 blocks a part of the beam reflected by the reflector 2, so that the irradiation angle of the head lamp can be adjusted.
그러나 반사판에 의해 반사되는 빔 중 일부가 플레이트의 이면에 닿으면서 소멸되어 벌브의 빔이 손실되는 결점을 가진다. 즉, 벌브에서 발산되는 빔을 모두 전방으로 조사하지 못하고 일부를 손실하게 되는 것이다.However, some of the beams reflected by the reflecting plate disappear as they reach the back surface of the plate, and have the disadvantage that the beam of the bulb is lost. That is, all the beams emitted from the bulb cannot be irradiated forward and some of them are lost.
이에 본 발명은 상기한 바와같이 손실되는 빔을 줄이기위해서 안출된 것으로, 이립티컬형 반사판과 바라폴라형 반사판으로 반사판을 분할하여 벌브에서 발산되는 전방으로 조사되는 조사량을 증대시켜 헤드램프의 배광성능을 향상시킬 수 있도록 하는 헤드램프의 배광장치를 제공하고자 하는데 그 목적이 있다.Accordingly, the present invention has been made to reduce the loss of the beam as described above, by dividing the reflector into an elliptically reflector and a barola polar reflector to increase the amount of radiation irradiated forward from the bulb to increase the light distribution performance of the headlamp. It is an object of the present invention to provide a light distribution device for a head lamp that can be improved.

이하 본 발명의 일 실시예에 따른 구성을 예시도면과 함께 보다 상세히 설명하면 다음과 같다.Hereinafter, the configuration according to an embodiment of the present invention in more detail with an exemplary drawing as follows.

본 발명은 도 2에 도시한 것처럼, 차량에 고정 설치되는 하우징(1) 내에는 상측과 하측으로 분할되어 파라볼라형인 상부 반사판(2a)과 이립티컬형 하부 반사판(2b)으로 구성된 반사판이 내입되고, 이 반사판(2a)(2b)의 후방에는 전방으로 빔을 조사할 수 있도록 이루어진 필라멘트를 갖는 벌브(3)가 설치되며, 이 반사판(2a)(2b)의 전면에는 이격관(5)에 의해 소정거리 이격된 비구면 렌즈(8)가 배치되는 한편, 이 이격관(5)의 내측 하단에는 플레이트(6)가 입설되며, 하우징(1)의 전후방에는 렌즈(7)와 더스트 커버(4)가 각각 결합되어있다.In the present invention, as shown in Fig. 2, in the housing 1 fixedly installed in a vehicle, a reflecting plate composed of an upper reflecting plate 2a and an elliptical lower reflecting plate 2b, which are divided into upper and lower sides, is embedded. At the rear of the reflecting plates 2a and 2b, a bulb 3 having a filament configured to irradiate a beam forward is provided, and the front of the reflecting plates 2a and 2b is predetermined by a spacer 5. While the aspherical lens 8 spaced apart from each other is disposed, a plate 6 is placed at the inner lower end of the spacer tube 5, and the lens 7 and the dust cover 4 are respectively located at the front and rear of the housing 1. Are combined.
이와같이 구성된 헤드램프의 동작을 설명한다.The operation of the headlamp configured as described above will be described.
본 발명의 동작을 설명하기이전에 파이폴라형 반사판과 이립티컬형 반사판에 대해 설명하면 다음과 같다. 먼저, 파라볼라형 반사판을 채용한 헤드램프는 도 3에서와 같이, 광원(9a)에서 발산된 빔이 파라볼라형 반사판(10)에 반사되면서 수평되게 전방으로 조사되는 특징을 갖는다.Before describing the operation of the present invention will be described with respect to the pipe-polar reflector and the elliptical reflector as follows. First, as shown in FIG. 3, the headlamp employing the parabolic reflector has a characteristic in which a beam emitted from the light source 9a is horizontally irradiated forward while being reflected by the parabola reflector 10.
또한, 이립티컬형 반사판을 채용한 헤드램프는 도 4에 도시한 것처럼, 광원(9b)에서 발산된 빔이 이립티컬형 반사판(11)에 반사되면서 소정거리에 있는 지점에서 교차되면서 상하로 조사되는 특징을 갖는다.In addition, as shown in FIG. 4, the head lamp employing the isolative reflective plate is irradiated up and down while the beam emitted from the light source 9b is reflected by the isotonic reflective plate 11 at a predetermined distance. Has characteristics.
이러한 특징으로 갖는 이립티컬형 반사판과 파라볼라형 반사판을 채용한 본 헤드램프에서 다기능레버의 조작으로 벌브(3)가 점등하게 되면, 벌브(3)에서 발산된 빔은 방사형으로 발산되어 상측 반사판(2a)과 하측 반사판(2b)에 각각 닿게 되고, 이어서 하측 반사판(2b)에 의해 반사된 빔은 종래의 헤드램프에서와 같이 반사되어 비구면 렌즈(8)에 조사된다. 또한 상측 반사판(2a)에 의해 반사된 빔은 파라볼라형 반사판의 특성에 의해 벌브(3)에서 발산된 빔이 수평 방향으로 반사되어 비구면 렌즈(8)에 조사된다.When the bulb 3 is turned on by the operation of the multifunction lever in this headlamp employing an ellipsisular reflector and a parabola reflector having such a feature, the beam emitted from the bulb 3 is radiated radially and the upper reflector 2a ) And the lower reflector 2b, respectively, and then the beam reflected by the lower reflector 2b is reflected and irradiated to the aspherical lens 8 as in the conventional headlamp. The beam reflected by the upper reflector 2a is irradiated to the aspherical lens 8 by the beam emitted from the bulb 3 being reflected in the horizontal direction due to the characteristics of the parabolic reflector.
이렇게 각기 다른 반사특성을 갖는 상/하부 반사판(2a)(2b)에 의해 반사되는 빔은 비구면 렌즈(8)를 통과하면서 수평방향의 빔으로 변환되어 렌즈(7)를 통해 전면으로 조사되게 된다. 물론 종래의 헤드램프에서와 같이, 이격관(5)의 내측 하단에 입설된 플레이트(6)가 반사판(2b)에 의해 반사된 빔의 일부를 차단함으로써, 헤드램프의 조사각도를 조절할 수 있는 것이다.The beam reflected by the upper and lower reflector plates 2a and 2b having different reflection characteristics is converted into a horizontal beam while passing through the aspherical lens 8 and irradiated to the front through the lens 7. Of course, as in the conventional headlamp, the plate 6 placed on the inner bottom of the separation tube 5 can block the part of the beam reflected by the reflector 2b, thereby controlling the irradiation angle of the headlamp. .
이상에서와 같이 본 발명은 벌브에서 발산되는 빔을 반사하는 반사판을 파라볼라형 반사판과 이립티컬형 반사판으로 상하 분할하여 설치함으로써, 벌브에서 발산되는 빔을 손실없이 전방으로 조사할 수 있는 것이다. 즉, 빔의 손실을 줄여 헤드램프의 배광성능을 향상시킬 수 있음은 물론이고, 더 나아가서는 헤드램프의 크기를 줄일 수 있는 효과가 있다.As described above, according to the present invention, the reflecting plate reflecting the beam emitted from the bulb is divided into upper and lower parts of the parabolic reflector and the helical reflector, so that the beam emitted from the bulb can be irradiated forward without loss. That is, the light loss performance of the head lamp can be improved by reducing beam loss, and further, the size of the head lamp can be reduced.
