본 발명은 하나의 광원과 광섬유를 이용하여 자동차의 모든 조명이 가능토록 하므로서 첫째, 전선군 및 반사경을 이용한 구성을 단순화하여 자동차의 경량화와 동시에 유효공간을 넓히고 둘째, 조명용 소모전력을 줄여 밧데리의 수명 및 출력을 증가시키며 셋째, 자동차의 모델 변화에 대해 광섬유의 교체만으로 가능케 하여 반사경과 프리즘 컷트의 설계, 제작에 소요되는 경비 및 시간의 낭비를 줄이며, 넷째, 열경화성수지의 사용을 줄여 제작경비 및 환경오염을 줄일 수 있도록 한 것이다.The present invention is to enable all the lighting of the car by using a single light source and optical fiber, firstly, simplify the configuration using the wire group and reflector to reduce the light weight and widen the effective space at the same time, and secondly, to reduce the power consumption for lighting to reduce the life of the battery And increase the output power. Third, it is possible to change the model of the car only by replacing the optical fiber, which reduces the cost and time required for the design and manufacture of the reflector and prism cut. Fourth, it reduces the use of thermosetting resin to reduce the production cost and environment. It is intended to reduce pollution.
일반적으로 사용되고 있는 자동차의 조명장치(전조등, 방향지시등, 안개등, 실내등, 계기등 등)은 개별광원을 가지고 반사경, 렌즈 등을 통하여 기능을 수행토록 한 것이기 때문에 제품의 구조 및 전원공급장치가 복잡해지고, 부피가 커지게 되어 유효공간이 줄어들고 또한 자동차의 모델이 변할 때마다 배광조건을 충족시키기 위해 반사경과 렌즈를 새로이 설계, 제작하는데 많은 인력과 시간 및 경비가 낭비되는 등의 문제점이 있는 것이다.In general, automobile lighting devices (headlights, direction indicators, fog lights, indoor lights, instrument lights, etc.) have individual light sources to perform functions through reflectors, lenses, etc., resulting in complicated product structure and power supply. In other words, there is a problem that a lot of manpower, time and expense are wasted in designing and manufacturing a new reflector and lens to satisfy the light distribution condition every time the model of the vehicle changes due to the increased volume.
본 발명은 이러한 종래의 제반 문제점을 시정하고자 광원으로부터 발광하는 빛을 반사경을 통하여 전방으로 집광시켜 광섬유의 선단부로 투사되게 하므로서 집광된 빛이 광섬유를 통하여 전송되게 하고, 전송된 빛은 광섬유의 끝단부에서 확산되게 하고, 확산된 빛은 다시 렌즈를 통하여 전방으로 직진시키되 직진된 빛은 렌즈를 통하여 배광규격에 맞도록 집광 및 확산시켜 사용토록 한 것으로서 본 발명의 실시예를 첨부도면에 따라 상세히 설명하면 다음과 같다.The present invention collects the light emitted from the light source to the front of the optical fiber through the reflector to correct the conventional problems, so that the collected light is transmitted through the optical fiber, the transmitted light is the end of the optical fiber In the above, the diffused light is straight forward again through the lens, but the straightened light is collected and diffused to meet the light distribution standard through the lens, so that an embodiment of the present invention will be described in detail according to the accompanying drawings. As follows.
본 발명은 크게 광원부(A)와 집광부(B), 전송부(C) 및 배광부(D)로 구분 구성된다.The present invention is largely divided into a light source unit (A), a light collecting unit (B), a transmission unit (C) and a light distribution unit (D).
광원부(A)는 다음과 같이 구성되어 진다.The light source part A is comprised as follows.
곡면을 갖는 반사경(10)의 곡면 내에 고휘도 방전램프(11)를 구성하여 방전램프(11)로부터 발광하는 빛이 반사경(10)에 반사되어 전방으로 집광되게 하되 방전램프(11) 전방에는 소형 압축반사경(12)를 구성한다.A high-brightness discharge lamp 11 is formed in the curved surface of the reflector 10 having a curved surface so that the light emitted from the discharge lamp 11 is reflected by the reflector 10 to be focused forward, but in front of the discharge lamp 11, compact compression. The reflector 12 is configured.
반사경(11) 전방에는 곡면부(13)가 형성된 보조반사경(14)을 구성하여 방전램프(11)로부터 발광하는 빛을 반사시켜 압축반사경(12)으로 반사되게 하고 압축반사경(12)를 통하여 반사된 빛은 다시 전방으로 집광되게 한다.An auxiliary reflector 14 having a curved portion 13 formed in front of the reflector 11 reflects the light emitted from the discharge lamp 11 to be reflected by the compression reflector 12 and is reflected by the compression reflector 12. The light is concentrated again forward.
본 발명의 광원부(A)를 구성함에 있어서 제2도에서와 같이 반사경(10)의 곡면내에 방전램프(11)를 설치하되 반사경(10)의 전방에 평면반사경(15)을 경사지게 설치하여 방전램프(10)로부터 발광하는 빛을 반사시켜 측방으로 집광되게 구성할 수도 있다.In the configuration of the light source unit A of the present invention, as shown in FIG. 2, the discharge lamp 11 is installed in the curved surface of the reflector 10, but the discharge lamp is installed by inclining the plane reflector 15 in front of the reflector 10. The light emitted from (10) may be reflected and condensed laterally.
광원부(A) 전방에 구성되는 집광부(B)는 다음과 같이 구성되어 진다.The light condensing part B formed in front of the light source part A is comprised as follows.
광원부(A)의 전방에 오목렌즈(20)를 설치하여 반사경(10)으로부터 반사되어 오는 빛을 굴절시켜 유효광량을 최적화할 수 있게 한다.The concave lens 20 is provided in front of the light source unit A to refract the light reflected from the reflector 10 to optimize the effective light amount.
즉 반사경(10)이나 압축반사경(12)으로부터 집광되는 빛을 입사시켜 굴절시키되 투사되는 빛을 가능한 투사각이 수평에 근접되게 하는 것이다.That is, the light collected from the reflector 10 or the compression reflector 12 is incident and refracted, so that the projected light is as close to the horizontal as possible.
오목렌즈(20) 전방에는 유리광섬유(21)를 설치하여 광원으로부터 발산되는 고온의 열을 차단할 수 있게 구성하므로서 전방에 구성되는 합성수지 광섬유를 고온의 열로부터 보호되게 한다.The glass optical fiber 21 is installed in front of the concave lens 20 to block high temperature heat emitted from the light source, thereby protecting the synthetic resin optical fiber configured in front of the concave lens 20 from high temperature heat.
집광부(B) 전면에 구성되는 전송부(C)는 빛의 전송이 용이한 광섬유(30)를 연결구성하되 광섬유(30) 외면에는 커버(31)를 피복하여 광섬유(30)에서 굴절되는 빛을 재반사시켜 전송시킬 수 있도록 하므로서 빛의 전송 효율을 높일 수 있도록 구성되어 있다.Transmitting unit (C) configured on the front of the light collecting portion (B) is connected to the optical fiber 30 that is easy to transmit light, but the light is refracted by the optical fiber 30 by covering the cover 31 on the outer surface of the optical fiber 30 It is configured to increase the transmission efficiency of light by allowing the reflection to be transmitted again.
이 때 광섬유(30)의 단면형태는 제6도의 도표에서와 같이 배광조건에 따라 여러형태로 구성하여 사용할 수 있으며, 필요한 배광조건에 따라 선택하여 사용할 수 있다.At this time, the cross-sectional shape of the optical fiber 30 can be used in various forms according to the light distribution conditions, as shown in the diagram of Figure 6, can be selected and used according to the necessary light distribution conditions.
전송부(C) 전면에 구성되는 배광부(D)는 다음과 같다.The light distribution unit D configured on the front of the transmission unit C is as follows.
즉 광섬유(30) 전방에 비구면렌즈(40)를 설치하여 광섬유(30)의 끝단으로부터 발산되는 빛이 비구면 렌즈(40)를 통과하면서 굴절되어 직진되게 하고, 비구면렌즈(40) 전방에는 프리즘컷트(prism cut)(41)가 형성된 렌즈(42)를 설치하여 렌즈(42)를 통하여 조사되는 빛이 프리즘컷트(41)에 의해 빛의 배광조건을 만족시킬 수 있도록 구성하여서 된 것이다.That is, the aspherical lens 40 is installed in front of the optical fiber 30 so that the light emitted from the end of the optical fiber 30 is refracted and go straight while passing through the aspherical lens 40, and in front of the aspherical lens 40 a prism cut ( By providing a lens 42 having a prism cut 41, the light irradiated through the lens 42 is configured to satisfy the light distribution condition of the light by the prism cut 41.
이 때 비구면렌즈(40) 전방에 구성되는 렌즈는 프리즘컷트(41)를 가진 렌즈(42)를 사용하지 않고 제8도에서와 같이 투명렌즈(43)를 사용하고 투명렌즈(43) 배면에 구성되는 렌즈를 비구면렌즈(40) 및 프리즘컷트(41)가 형성된 렌즈(42)를 통과한 빛의 배광을 만족시킬 수 있도록 설계, 제작된 타원렌즈(44)를 사용할 수도 있다.In this case, the lens formed in front of the aspherical lens 40 uses the transparent lens 43 as shown in FIG. 8 without using the lens 42 having the prism cut 41 and is formed on the rear surface of the transparent lens 43. An elliptic lens 44 designed and manufactured to satisfy the light distribution of the light passing through the lens 42 having the aspherical lens 40 and the prism cut 41 may be used.
이와 같이 구성된 본 발명은 방전램프(11)를 켜면 방전램프(11)가 발광하고 발광된 빛은 반사경(10)에 반사되어 전방에 구성된 오목렌즈(20)로 집광되고 전방으로 발산된 빛 중 오목렌즈(20)로 집광되지 못하고 보조반사경(14)으로 조사된 빛은 보조반사경(14)의 곡면부(13)에 부딪혀 반사된 다음 다시 압축반사경(12)으로 반사되어 전방에 위치한 오목렌즈(20)로 재집광되게 하므로서 빛의 손실을 최소화하게 된다.According to the present invention configured as described above, when the discharge lamp 11 is turned on, the discharge lamp 11 emits light and the emitted light is reflected by the reflector 10 and condensed among the light emitted by the concave lens 20 configured in the front and emitted forward. The light irradiated by the auxiliary reflector 14 without being condensed by the lens 20 is reflected by hitting the curved portion 13 of the auxiliary reflector 14 and then reflected by the compression reflector 12, and thus the concave lens 20 positioned in front of the lens 20. Recondensing to minimize the loss of light.
오목렌즈(20)로 집광된 빛은 오목렌즈(20)를 통과하면서 빛이 굴절되어 거의 전방수평방향으로 진행하여 유리광섬유(21)로 입사되고 이때 입사되는 빛의 각도는 30°이하가 이상적이며 이는 빛이 전송부(C)에 구성된 광섬유(30)내에서 지그재그로 굴절되면서 전송될 수 있는 한계각이다.The light condensed by the concave lens 20 passes through the concave lens 20 and the light is refracted and proceeds almost forward to the glass optical fiber 21. The incident light angle is ideally 30 ° or less. This is a limit angle at which light can be transmitted while being refracted in a zigzag in the optical fiber 30 configured in the transmission unit C.
따라서 오목렌즈(20)의 설계, 제작시 이점을 고려하여야 하며 이때 유리광섬유로 입사되는 빛의 입사각은 가능한 적으면 유리하다.Therefore, the design and fabrication advantages of the concave lens 20 should be taken into consideration. In this case, the incident angle of light incident on the glass optical fiber is advantageous if possible.
유리광섬유(21)로 입사된 빛은 다시 광섬유(30)로 전달되고 광섬유(30)로 전달된 빛은 지그재그로 굴절을 반복하면서 광섬유(30)의 끝단부에서 입사각과 동일한 각도로 투사되어 전방에 위치한 비구면렌즈(40)로 조사된다.The light incident on the glass optical fiber 21 is transmitted to the optical fiber 30 again and the light transmitted to the optical fiber 30 is projected at the same angle as the incident angle at the end of the optical fiber 30 while repeating refraction in a zigzag. It is irradiated with the aspherical lens 40 located.
오목렌즈(20)와 광섬유(30)사이에 구성된 유리광섬유(21)는 광원으로부터 발생하는 고온의 열을 차단하여 합성수지로 구성된 광섬유(30)를 고온의 광원으로부터 보호하기 위한 것이다.The glass optical fiber 21 formed between the concave lens 20 and the optical fiber 30 is for protecting the optical fiber 30 made of synthetic resin from the high temperature light source by blocking high temperature heat generated from the light source.
비구면렌즈(40)로 조사된 빛은 비구면렌즈(40)를 통과하면서 빛이 내측으로 굴절되어 거의 수평방향으로 조사되고 비구면렌즈(40)로부터 조사되어 온 빛은 렌즈(42)에 구성된 프리즘컷트(41)에 의해 적절한 각도로 굴절되어 자동차의 필요한 부분에 조명된다.The light irradiated by the aspherical lens 40 passes through the aspherical lens 40 and the light is refracted inwardly and irradiated in almost horizontal direction. 41) is refracted at an appropriate angle to illuminate the required part of the car.
전송부(C)에 사용되는 광섬유(30)의 단면형상은 배광조건에 따라,,및형의 광섬유(30)를 한 개 혹은 다수의 광섬유 묶음을 사용할 수 있으며 광섬유(30) 외면에 피복된 커버(31)는 광섬유(30)내에서 지그재그로 반복되는 빛의 굴절이 보다 원활히 이루어지도록 하여 전송효율을 높이기 위한 것이다.The cross-sectional shape of the optical fiber 30 used for the transmission unit C depends on the light distribution condition. , , And Type of optical fiber 30 can be used one or a plurality of optical fiber bundles and the cover 31 is coated on the outer surface of the optical fiber 30 so that the refraction of the zigzag repeated light in the optical fiber 30 is made more smoothly This is to increase the transmission efficiency.
상기에서 광섬유(30)의 단면형상을 특정한 형태로 형성한 것은 광섬유(30)를 통하여 비구면렌즈(40)로 조사된 빛이 렌즈(42)를 통과하면서 전방으로 조사될 때 규격된 배광조건에 맞도록 전방으로 조사될 수 있도록 하기 위한 것이다.The cross-sectional shape of the optical fiber 30 is formed in a specific shape as described above when light irradiated to the aspherical lens 40 through the optical fiber 30 is irradiated to the front while passing through the lens 42. It is intended to be irradiated forward.
제8도에서와 같이 프리즘컷트(41)가 없는 투명렌즈(43)를 사용하고자 할 경우에는 타원렌즈(44)를 사용하여 배광을 만족시킬 수 있다.As shown in FIG. 8, when the transparent lens 43 without the prism cut 41 is to be used, the light distribution can be satisfied using the ellipse lens 44.
즉 타원렌즈(44)의 설계, 제작시 타원렌즈의 곡면과 높이 및 폭의 비율을 계산하여 상기에서 사용된 비구면렌즈(40)와 프리즘컷트(41)가 형성된 렌즈(42)를 통과한 빛의 배광조건과 동일하게 제작 사용하므로서 프리즘 컷트가 필요없는 투명렌즈(43)를 사용할 수 있게 된다.That is, when designing and manufacturing the elliptical lens 44, the ratio of the curved surface, the height, and the width of the elliptical lens is calculated to determine the amount of light passing through the lens 42 having the aspherical lens 40 and the prism cut 41. By using and manufacturing the same light distribution conditions, the transparent lens 43 without the prism cut can be used.
위에서 설명한 바와 같은 구성으로 하나의 광원으로부터 여러가닥의 광섬유를 분리시켜 방향지시등이나 안개등, 실내등 및 계기등 등의 모든 자동차 조명장치에 동시 적용하여 사용가능케 된다.With the configuration as described above, it is possible to separate several optical fibers from a single light source and apply them to all automotive lighting devices such as direction indicators, fog lights, interior lights, and instrument lights simultaneously.
따라서 본 발명은 종래와 같이 복잡한 전선군 및 반사경을 이용한 장치가 매우 단순해 지므로 자동차를 경량화 하면서 유효공간을 최대로 넓힐 수 있으며, 또한 모델 변화에 대하여 광섬유의 교체만으로 가능해지므로 반사경과 프리미즘컷트의 설계, 제작에 소요되는 경비와 많은 시간 및 인력을 절감할 수 있으며, 하나의 광원을 사용함에 따른 자동차의 소모전력을 줄여 밧데리의 수명연장과 함게 출력을 증진시킬 수 있게 되는 등의 효과가 있는 것이다.Therefore, in the present invention, since the apparatus using a complex wire group and a reflector is very simple as in the related art, the effective space can be maximized while reducing the weight of the vehicle, and also it is possible to change the model only by replacing the optical fiber. It can reduce the cost, time and manpower required for design and manufacture, and can reduce the power consumption of a car by using a single light source, thereby increasing output with battery life. .
