본고안은 프리즘 컷(Prism cut)을 하지 않은 전면 렌즈와 비구면 평 오목렌즈 및 비포물 반사기로 구성되는 자동차용 전조등(HEAD LAMP)에 관한 것이다.The present invention relates to a HEAD LAMP for automobile, which is composed of a front lens without a prism cut, an aspherical flat concave lens, and a non-parabolic reflector.
종래의 자동차용 전조등(9)은 이중 필라멘트(10), (10')로 된 할로겐 전구(11)와 비교적 큰 반사기(12)로 구성되고 전면렌즈(13)에는 프리즘 컷(14)을 하여 일정규격의 빔 패턴(Beam pattem)이 형성되게 한것이므로 빔 패턴 형성에 소요되는 프리즘 컷의 수와 방향때문에 전면렌즈(13)의 면적이 일정크기 이상이어야 하고 따라서 전조등(9)의 크기도 일정이하로 축소 할수 없으며 전면렌즈(13)의 경사각도는 일정각도 앞쪽으로 기울어져 있어 공기 저항을 많이 받으며 로우빔(Low Beam) 상태에서는 대향 차량 운전자의 시계 방해가 되지 않도록 컷 오프라인(cut off Line) (15)이 형성되도록 하고 있으나 전면렌즈(13)에서 프리즘 컷(14)에 의한 난반사등으로 인하여 정확한 로우 빔 패턴의 형성이 어려워 대향 운전자의 시계 보호가 미흡할뿐 아니라 국가마다 상이한 컷 오프라인(15) 때문에 그에 따라 여러가지 규격의 모델이 개발되어야 하며 렌즈에 프리즘 컷을 형성하기 위한 설계 작업에 많은 인력과 시간이 소모되는 등의 문제가 있는 것이었다.The conventional automotive headlight 9 is composed of a halogen bulb 11 of double filaments 10, 10 'and a relatively large reflector 12, and a prism cut 14 on the front lens 13, which is fixed. Since the beam pattern of the standard is formed, the area of the front lens 13 should be more than a certain size because of the number and direction of prism cuts required to form the beam pattern. Therefore, the size of the headlamp 9 should be less than a certain size. The angle of inclination of the front lens 13 is inclined forward by a certain angle so that it receives a lot of air resistance and cut off line so as not to disturb the clock of the opposing vehicle driver in the low beam state. ), However, it is difficult to form an accurate low beam pattern due to the diffuse reflection of the prism cut 14 in the front lens 13, so that the counter driver's watch protection is insufficient and the cut offline ( Therefore, various standard models have to be developed accordingly, and a lot of manpower and time are required to design a prism cut on the lens.
본고안은 이러한 제반문제점을 해결하기 위하여 비포물반사기에 의하여 반사되는 전구의 불빛이 오목렌즈를 통과하면서 적절히 배광되어 프리즘컷 없이도 만족한 하이빔(High Beam)패턴을 형성하도록하고 로우빔(Low Beam)은 차광판에 의하여 보다 정확히 형성되도록한 것으로서 이를 첨부 도면에 따라 상세히 설명하면 다음과 같다.In order to solve these problems, this paper aims to ensure that the light of the bulb reflected by the parabolic reflector is properly distributed while passing through the concave lens to form a satisfactory high beam pattern without a prism cut. Is to be formed more accurately by the light-shielding plate as described in detail according to the accompanying drawings as follows.
비포물 반사기(3)와 비구면 평오목렌즈(4)및 프리즘컷이 없는 전면렌즈(5)로 전조등을 구성하되 오목렌즈(4)는 반사기(3)의 촛점(F1)내측에 위치하도록하고 오목렌즈(4)의 촛점(F2)은 반사기(3)의 촛점(F1) 외측에 형성되게 오목렌즈(4)의 구면을 설정하므로서 광원(6)의 의의로 부터 반사기(3)에 입사한 광선은 촛점(F1)을 향해 반사되고 오목렌즈(4)를 통과하젼서 굴절하여 하이빔패턴이 형성되게 하였으며 오목렌즈(4)와 반사기(3)의 사이에 차광판(7)을 부착하여 상방향의 광선을 차단토록 하므로서 정확한 규격의 컷오프라인을 갖는 로우빔 패턴이 형성되게 한 것이다.The headlamps consist of a non-parabolic reflector (3), an aspheric spherical lens (4) and a front lens (5) without a prism cut, but the concave lens (4) is positioned inside the focal point (F 1 ) of the reflector (3). The focal point F 2 of the concave lens 4 is incident on the reflector 3 from the significance of the light source 6 by setting the spherical surface of the concave lens 4 to be formed outside the focal point F 1 of the reflector 3. One ray is reflected toward the focal point F 1 and refracted through the concave lens 4 to form a high beam pattern, and a light shield plate 7 is attached between the concave lens 4 and the reflector 3 to form an image. By blocking the light beam in the direction, a low beam pattern having a precise cutoff line is formed.
본고안에서 비구면이라함은 원호로 구성된 통상의 구면과는 달리 구면선상의 각점에서 중심점 까지의 거리가 각기 다른 곡면을 뜻하고 미포물 이라함은 포물면상의 한점과 이 포물면의 두촛점 까지의 거리의 합이 일정하지 않은 포물면을 뜻한다.In this paper, aspheric surface means a curved surface that has different distances from each point on the spherical line to the center point. Unlike non-spherical surface, unsculpture means the sum of the distance between one point on the parabola and two focal points of the parabola. This means non-uniform paraboloids.
미설명 부호(1)은 로우빔용 램프(2)는 하이빔용 램프(8)은 하우징이다.Reference numeral 1 denotes a low beam lamp 2 and a high beam lamp 8 a housing.
이와같이 구성된 본고안은 제2도에서와 같이 전조등내에 차광판(7)이 없는 하이빔용 램프(2)와 차광관(7)이 부착된 로우빔용 램프(1)를 한조로 설치하여 사용하며 광원(6)이 점등되면 광원(6)으로부터 반사기(3)에 입사한 광선은 촛점을 향해 반사되고 오목렌즈(4)를 통과하면서 굴절하여 하이빔패턴을 형성한다.In this configuration, the high beam lamp 2 without the light shielding plate 7 and the low beam lamp 1 with the light shielding tube 7 are installed in the headlamp as shown in FIG. When () is turned on, light rays incident on the reflector 3 from the light source 6 are reflected toward the focal point and are refracted while passing through the concave lens 4 to form a high beam pattern.
즉 광축과 평행하게 입사한 광선은 오목렌즈(4)의 반대측 촛점(F2')에서 광선이 나오는 것처럼 굴절하고 오목렌즈(4)의 중심을 향해서 입사한 광선은 굴절하지 않고 직진하고 촛점(F2)을 향해서 입사한 광선은 광축에 평행하도륵 굴절하여 만족한 배광의 하이빔패턴이 형성되는 것이다.That is, the light rays incident in parallel with the optical axis are refracted as if the light rays come out from the focal point F 2 ′ of the concave lens 4, and the light rays incident toward the center of the concave lens 4 go straight without refraction and are focused (F). Light rays incident toward 2 ) are refracted even parallel to the optical axis to form a satisfactory light beam high beam pattern.
그러나 차광판(7)이 부착된 로우빔용램프(1)에서는 오목렌즈(4)와 반사기(3) 사이에 부착된 차광판(7)이 상방향의 광선을 차단하여 로우빔패턴을 형성한다.However, in the low beam lamp 1 to which the light blocking plate 7 is attached, the light blocking plate 7 attached between the concave lens 4 and the reflector 3 blocks the light beam in the upward direction to form a low beam pattern.
이때 차광판(7)의 차단에 의하여 형성되는 컷오프라인은 프리즘컷에 의한 난반사등이 없어 매우 정확하게 이루어진다.At this time, the cutoff line formed by the blocking of the light shielding plate 7 is very accurate because there is no diffuse reflection by the prism cut.
따라서 본고안은 전면렌즈(5)에 프리즘컷을 하지 않고도 만족한 배광효과를 얻을수 있어 프리즘컷 설계에 따른 인력과 시간을 절감할수 있고 프리즘컷의 수와 방향떼문에 일정크기 이상으로 하여야 하는 전면렌즈를 자유롭게 축소 할수 있어 전조등을 보다 소형화 및 경량화 할수 있게하며 또 컷오프라인을 프리즘컷에 의하지 않고 차광판(7)에 의하여 형성하므로 난반사등이 없어 컷오프라인이 정확하게 형성되어 대향운전자의 시계보호 효과가 매우 높고 나라마다 상이한 컷오프라인 때문에 그에 따라 여러 종류의 프리즘컷을 갖는 전조등을 개발하여야 하는 낭비가 없고 단순히 차광판(7)의 설계만 변경하므로서 어떤 나라에도 전합한 전조등을 생산할 수 있으며 전면렌즈(5)의 경사각을 임의로 뒷쪽으로 기울게 할수 있어 공기의 저항을 적게 받는 차체를 생산할 수 있는 등의 효과가 있는 것이다.Therefore, this paper can achieve satisfactory light distribution effect without prism cut on the front lens (5), which can save manpower and time according to the prism cut design, and the front lens should be over a certain size in the number and direction of prism cut. It is possible to freely reduce the headlights, making the headlights more compact and lighter. Also, since the cutoff line is formed by the shading plate 7 instead of the prism cut, the cutoff line is precisely formed because there is no diffuse reflection, so the counter driver's watch protection effect is very high. There is no waste to develop headlights with different kinds of prism cuts due to different cutoff lines in different countries, and it is possible to produce the headlights in any country by simply changing the design of the shading plate 7 and the inclination angle of the front lens 5 Can be tilted backwards at any time It is possible to produce a sieve and the effect is.
