Description
본 발명은 자동차의 전조등에 적용되는 이중 광학 프리즘을 이용한 빔각도 조절장치(Beam Angle Control Decive with Utilized Duo-Optic Prism)에 관한 것이다.The present invention relates to a beam angle control device (Beam Angle Control Decive with Utilized Duo-Optic Prism) using a dual optical prism applied to the headlights of the automobile.
종래의 자동차 전조등은 광축이 상향과 하향으로만 각도조절할 수 있도록 고정되어 있다. 이 전조등은 하우징의 전면에 광학 프히즘을 갖는 렌즈가 부착되고, 내부에 반사기와 벌브가 설치된 것이다.Conventional automotive headlamps are fixed so that the optical axis can only be angled upward and downward. The headlamp is equipped with a lens having an optical prism on the front of the housing, and a reflector and a bulb inside.
그러나, 상기와 같이 전조등의 광축이 상하로만 각도조절되면 주차시나 험로주행시 옆방향의 물체를 운전자가 식별하는데 어려움이 있어 안전성을 하는 요인으로 작용하게 된다.However, when the optical axis of the headlamp is adjusted only up and down as described above, the driver has difficulty in identifying the object in the lateral direction when parking or driving on a bad road, thereby acting as a safety factor.
본 발명의 목적은 주차나 험로 주행시 옆방향의 물체 식별이 용이하도록 이중 프리즘을 이용하여 광선의 방사각을 옆으로 넓힐 수 있는 빔각도 조절장치를 제공하는데 있는 것이다.An object of the present invention is to provide a beam angle control device that can widen the radiation angle of the light beam by using a double prism to facilitate the identification of the object in the lateral direction when parking or driving on a bad road.

상기 목적을 달성하기 위한 본 발명의 구성을 첨부된 도면에 의하여 설명하면 다음과 같다.Referring to the accompanying drawings, the configuration of the present invention for achieving the above object is as follows.
본 발명은 내면에 광학 프리즘(1a)을 갖는 렌즈(2)가 부착되는 하우징(3)과; 광원으로부터 투사되는 빛이 상기 렌즈(2)의 광학 프리즘(1a)을 통하여 확산가능하게 굴절시킬 수 있는 광학 프리즘(1b)이 외면에 형성되고, 상기 하우징(3)의 렌즈(2) 후방에 좌우이동 가능하게 설치되며, 일측에 랙(4)이 형성된 보조렌즈(5)와; 이 보조렌즈(5)의 랙(4)을 이동시키는 피니언(6)이 축설치된 모터(7); 그리고 이 모터(7)를 구동시키는 작동스위치(8)를 구비시킨 것이다.The present invention comprises a housing (3) to which a lens (2) having an optical prism (1a) is attached to an inner surface thereof; An optical prism 1b is formed on the outer surface of which light projected from the light source can be refracted to be diffused through the optical prism 1a of the lens 2, and left and right behind the lens 2 of the housing 3. An auxiliary lens 5 installed to be movable and having a rack 4 formed at one side thereof; A motor 7 on which a pinion 6 for moving the rack 4 of the auxiliary lens 5 is installed; And the operation switch 8 which drives this motor 7 is provided.
상기한 렌즈(2)의 광학 프리즘(1a) 단위체는 볼록한 구면을 이루고, 상기한 보조렌즈(5)의 광학 프리즘(1b) 단위체는 상기 렌즈(2)의 광학 프리즘(1a) 단위체와 동일한 곡률과 크기의 오목한 구면으로 이루어진 것이다.The optical prism 1a unit of the lens 2 has a convex spherical surface, and the optical prism 1b unit of the auxiliary lens 5 has the same curvature as that of the optical prism 1a unit of the lens 2. It consists of a concave spherical sphere.
상기 하우징(3)의 렌즈(2) 후방에는 상하로 가이드 홈(9a,9b)이 형성되어 이 가이드 홈(9a,9b)에 보조렌즈(5)의 상하면이 좌우로 유동가능하게 끼워진 것으로 랙(4)의 일측과 하우징(3) 사이에는 리턴스프링(10)을 설치하여 보조렌즈(5)가 모터(7)에 의하여 일측으로 이동된 후 작동스위치(8)를 OFF시키면 보조렌즈(5)가 원위치로 복귀되도록 한 것이다. 상기에서 보조렌즈(5)의 원위치라고 하는 것은 제3(a)도와 같이 보조렌즈(5)의 광학 프리즘(1b)과 렌즈(2)의 광학 프리즘(1a)이 서로 일치하는 것으로, 이때에는 광선이 정상적으로 방사된다.Guide grooves 9a and 9b are formed up and down behind the lens 2 of the housing 3 so that the upper and lower surfaces of the auxiliary lens 5 are inserted into the guide grooves 9a and 9b so as to be movable left and right. A return spring 10 is installed between one side of the housing 4 and the housing 3 so that the auxiliary lens 5 is moved to one side by the motor 7, and then the operation switch 8 is turned off. It is to return to the original position. The original position of the auxiliary lens 5 is that the optical prism 1b of the auxiliary lens 5 and the optical prism 1a of the lens 2 coincide with each other as shown in FIG. 3 (a). Is radiated normally.
본 발명은 상기와 같은 구성에 따라, 제3(a)도와 같은 상태에서 주차시나 험로를 지날 때 옆방향의 시야 확보를 위해 작동스위치(8)를 ON시키면 모터(7)가 구동하여 피니언(6)이 랙(4)을 이동시키므로 보조렌즈(5)는 하우징(3) 내에서 가이드홈(9a,9b)을 따라 옆으로 이동하여 제3(b)도와 같이 광학 프리즘(1b)이 렌즈(2)의 광학 프리즘(1a)과 교차하면서 정지한다.According to the configuration as described above, when the operation switch 8 is turned on to secure the lateral view when parking or passing a bad road in the state as shown in the third (a), the motor 7 drives the pinion 6 ) Moves the rack 4 so that the auxiliary lens 5 moves sideways along the guide grooves 9a and 9b in the housing 3 so that the optical prism 1b is moved to the lens 2 as shown in FIG. It stops intersecting with the optical prism 1a of ().
이에 따라 광원으로부터 나오는 광선은 보조렌즈(5)의 광학 프리즘(1b)을 거치면서 굴절되고, 다시 렌즈(2)의 광학 프리즘(1a)을 통하여 굴절되어 확산되므로 광선의 방사각은 넓어진다. 이후에 작동스위치(8)를 OFF시키면 랙(4)이 리턴스프링(10)에 의하여 당겨지므로 보조렌즈(5)는 원위치로 복귀한다.Accordingly, the light rays emitted from the light source are refracted while passing through the optical prism 1b of the auxiliary lens 5, and are further refracted and diffused through the optical prism 1a of the lens 2, thereby increasing the radiation angle of the light beam. When the operation switch 8 is turned off later, the auxiliary lens 5 returns to its original position because the rack 4 is pulled by the return spring 10.
이와같은 본 발명은 주차 및 험로 주행시에 빛을 옆으로 확산시키므로 시계 확보에 유리하고, 차량의 일반적인 선회시에도 시계확보에 유리하다. 또, 상기한 모터 대신 조향흴에 연동하도록 하면 차량의 선회시에 광폭의 빔을 얻을 수 있다.The present invention is advantageous to secure the clock because it diffuses the light sideways during parking and rough road driving, it is advantageous to secure the clock even during the general turning of the vehicle. In addition, when the motor is linked to the steering wheel instead of the motor described above, a wide beam can be obtained when the vehicle is turning.
