Description

차량용 전조등 조립체{Light module assembly for vehilce}Vehicle headlight assembly {Light module assembly for vehilce}

본 발명은 차량용 전조등 조립체에 관한 것으로, 보다 상세하게는 구조를 개선함으로써 눈부심을 방지하고, 중심부의 직진성을 완화시키고 화소당 발광면적의 크기를 확대할 수 있는 차량용 전조등에 관한 것이다.The present invention relates to a headlight assembly for a vehicle, and more particularly, to a headlight for a vehicle capable of preventing glare by improving the structure, reducing the straightness of the center, and increasing the size of the light emitting area per pixel.

일반적으로 차량에는 전조등이 장착됨으로써 야간이나 안개시 전방을 조사함으로써 안전운전을 할 수 있다.In general, a vehicle can be safely driven by irradiating the front at night or in fog since a headlamp is installed.

그리고, 차량용 전조등으로는 다양한 램프가 적용될 수 있는 바, 그 일예로 엘이디(LED : Light Emitting Diode) 램프가 적용될 수 있다.In addition, various lamps may be applied as the vehicle headlight, and an example of the LED (Light Emitting Diode) lamp may be applied.

이러한 엘이디는 화합물 반도체 특성을 이용해서 전기 신호를 빛으로 변환시These LEDs use compound semiconductor properties to convert electrical signals into light.

켜 신호를 보내고 받는데 사용되는 반도체의 일종이다. 이러한 엘이디 소자를 이용한 엘이디 등기구가 반영구적인 수명으로 인하여 최근 많이 보급되고 있다. 즉, 엘이디 등기구는 엘이디 소자를 다수개 배치하고, 이 엘이디 소자에 전원을 공급함으로써 발광하는 방식이다.It is a type of semiconductor used to send and receive signals. LED luminaires using such an LED element have recently been widely used due to their semi-permanent lifespan. That is, the LED luminaire is a method of emitting light by arranging a plurality of LED elements and supplying power to the LED elements.

이러한 엘이디 등기구는 종래의 나트륨등 혹은 수은등에 비하여 엘이디를 사용함으로써 친환경적이고, 또한, 10만시간 이상의 수명으로 인하여 더욱 사용이 증가하고 있다. 또한, 엘이디 등기구는 방전등과 비교하여 저전력을 소비하며, 높은 색온도로 시인성이 우수하고, 연색성이 좋은 장점이 있다.These LED luminaires are eco-friendly by using LEDs compared to conventional sodium lamps or mercury lamps, and their use is increasing due to their lifespan of more than 100,000 hours. In addition, the LED luminaire consumes less power compared to a discharge lamp, has excellent visibility due to a high color temperature, and has good color rendering properties.

그러나, 이러한 종래의 엘이디 등기구는 반사판의 구조가 효율적이지 못하여 엘이디로부터 발산되는 광을 도로 조명용등에 맞게 효율적으로 집광시키지 못하는 문제점이 있다.However, such a conventional LED luminaire has a problem in that the structure of the reflective plate is not efficient, so that the light emitted from the LED cannot be efficiently condensed according to the road lighting lamp.

또한, 종래의 엘이디는 비구면 반사렌즈를 장착하는 경우도 있으나, 이 경우 360도 각도로 발광하나 엘이디는 직진 조사각이 크고 측면 조사각은 일부이므로 측면 발광이 미약하여 전체적으로 화소당 발광면적을 확장하는데 제약이 있다.In addition, the conventional LED may be equipped with an aspherical reflective lens, but in this case, it emits light at a 360 degree angle. There are restrictions.

따라서, 비구면 반사갓의 크기를 확장하기 어려우므로 동일 면적에 많은 엘이디를 배치하여 사용하게 된다.Therefore, since it is difficult to expand the size of the aspherical reflector, many LEDs are arranged in the same area and used.

특허등록 제 10-1406214호(명칭:차량용 램프)Patent Registration No. 10-1406214 (Name: Vehicle Lamp)

본 발명의 목적은, 구조를 개선함으로써 도금을 하지 않고도 반사율을 높일 수 있으며, 또한 눈부심을 방지하고, 중심부의 직진성을 완화시키고 화소당 반사면적을 확장할 수 있는 전조등을 제공하는 것이다.An object of the present invention is to provide a headlamp capable of increasing the reflectance without plating by improving the structure, preventing glare, reducing the straightness of the center, and expanding the reflective area per pixel.

상기한 같은 본 발명의 목적을 달성하기 위하여, 본 발명의 일 실시예는 In order to achieve the object of the present invention as described above, an embodiment of the present invention is

프레임(3)상에 구비되는 기판(12)과, 기판(12)상의 회로층에 장착되어 광을 조사하는 광원(14)과, 광원(14)에서 발생된 빛을 전방 및 사방으로 조사하는 렌즈부(10)를 포함하는 전조등 조립체(1)에 있어서,A substrate 12 provided on the frame 3, a light source 14 mounted on a circuit layer on the substrate 12 to irradiate light, and a lens for irradiating the light generated from the light source 14 forward and in all directions In a headlamp assembly (1) comprising a part (10),

상기 렌즈부(10)는 광원(14)에서 조사된 광을 중심부로 집중시키는 촛점 렌즈부(16)와;The lens unit 10 includes a focal lens unit 16 for concentrating the light irradiated from the light source 14 to the center;

촛점 렌즈부(16)의 외주에 형성되며 촛점 렌즈부(16)에서 반사된 광을 전방으로 조사하는 확산 렌즈부(18)와; 그리고a diffusion lens unit 18 formed on the outer periphery of the focal lens unit 16 and irradiating the light reflected from the focal lens unit 16 forward; and

기판(12)상에 결합되며, 광원(14)과, 촛점 렌즈부(16)와, 확산 렌즈부(18)를 감쌈으로써 광의 통로가 되는 사출물(5)을 포함하는 전조등 조립체(1).A headlamp assembly (1) coupled on a substrate (12), comprising a light source (14), a focusing lens section (16), and an extrudate (5) enclosing the diffusing lens section (18) to become a passage for light.

본 발명에 따른 차량용 전조등 조립체는 렌즈부의 중심은 오목하게 형성하고, 그 주위는 계단형상으로 형성함으로써 광원에서 발생된 광이 중심의 반사면에서 일부 광은 직진하고 나머지 광은 렌즈의 내측방향으로 조사되어 계단형상의 렌즈면에 의하여 반사되어 직진하게 되므로 눈부심을 방지하고, 중심부의 직진성을 완화시키고 화소당 반사면적의 크기를 확대할 수 있는 장점이 있다.In the headlight assembly for a vehicle according to the present invention, the center of the lens unit is concave and the periphery is formed in a step shape, so that some light from the light source goes straight on the reflective surface of the center and the remaining light is irradiated in the inner direction of the lens. It is reflected by the step-shaped lens surface and goes straight, so it has the advantage of preventing glare, reducing the straightness of the center, and increasing the size of the reflection area per pixel.

이하, 본 발명의 일 실시예에 따른 차량용 전조등에 대하여 첨부된 도면을 참조하여 상세하게 설명한다.Hereinafter, a headlamp for a vehicle according to an embodiment of the present invention will be described in detail with reference to the accompanying drawings.

도 1 내지 도 5를 참조하면, 차량용 전조등 조립체(1)는 프레임(3)상에 구비되는 기판(12)과; 기판(12)상의 회로층에 장착되어 광을 조사하는 광원(14)과; 광원(14)에서 발생된 빛을 전방 및 사방으로 조사하는 렌즈부(10)를 포함한다.1 to 5 , the vehicle headlight assembly 1 includes a substrate 12 provided on a frame 3 ; a light source 14 mounted on the circuit layer on the substrate 12 to irradiate light; It includes a lens unit 10 for irradiating the light generated from the light source 14 forward and in all directions.

이러한 차량용 전조등에 있어서,In such a vehicle headlight,

기판(12)은 다양한 종류의 기판(12)이 적용가능하며, 예를 들면 벤더블 메탈 피씨비(Bendable Metal PCB;BMPCB) 혹은 메탈 피씨비를 적용한다.As the substrate 12 , various types of substrates 12 are applicable, for example, a bendable metal PCB (BMPCB) or a metal PCB is applied.

이러한 구조를 갖는 전조등에 있어서, 기판(12)은 통상적인 구조의 메탈기판(12)으로서 절연층과, 회로층과, 메탈층으로 구성된다.In the headlamp having such a structure, the substrate 12 is a metal substrate 12 having a conventional structure, and is composed of an insulating layer, a circuit layer, and a metal layer.

그리고, 이러한 기판(12)은 자동차의 전방 전조등에 주로 사용되는 바, 전방을 조사하여야 하므로 프레임(3)상에서 전방을 향하도록 배치된다.And, since the substrate 12 is mainly used for the front headlight of a vehicle, it is disposed so as to face forward on the frame 3 because the front has to be irradiated.

또한, 광원(14)은 엘이디 소자를 포함하며, 전원회로가 형성된 기판(12)상에 실장된다. 이때, 엘이디 소자는 바람직하게는 백색광을 발생하는 백색 엘이디(White LED)를 포함한다. 물론, 등기구의 사용 목적에 따라 적색 혹은 녹색 엘이디도 적절하게 배치할 수 있다.In addition, the light source 14 includes an LED element and is mounted on the substrate 12 on which the power circuit is formed. In this case, the LED device preferably includes a white LED emitting white light. Of course, depending on the purpose of use of the luminaire, a red or green LED may be appropriately disposed.

따라서, 외부에서 공급된 전원이 기판(12)에 공급되면, 엘이디 소자가 발광을 하게 된다.Therefore, when externally supplied power is supplied to the substrate 12, the LED element emits light.

그리고, 발광된 빛은 렌즈부(10)를 통하여 직진하거나 사방으로 조사될 수 있다.In addition, the emitted light may be irradiated in a straight line or in all directions through the lens unit 10 .

상기 렌즈부(10)는, 광원(14)에서 조사된 광을 중심부로 집중시키는 촛점 렌즈부(16)와; 촛점 렌즈부(16)의 외주에 형성되며 촛점 렌즈부(16)에서 반사된 광을 전방으로 조사하는 확산 렌즈부(18)와; 기판(12)상에 결합되며, 광원(14)과, 촛점 렌즈부(16)와, 확산 렌즈부(18)를 감쌈으로써 광의 통로가 되는 사출물(5)을 포함한다.The lens unit 10 includes: a focal lens unit 16 for concentrating the light irradiated from the light source 14 to the center; a diffusion lens unit 18 formed on the outer periphery of the focal lens unit 16 and irradiating the light reflected from the focal lens unit 16 forward; It is coupled on the substrate 12 and includes a light source 14 , a focal lens unit 16 , and an ejection product 5 that wraps around the diffusion lens unit 18 and serves as a passage for light.

이러한 렌즈부(10)를 상세하게 설명하면, 촛점 렌즈부(16)는 전체 렌즈의 중심부에 형성되며 오목한 형상을 갖음으로써 광을 중심부로 집중시킨다.When the lens unit 10 is described in detail, the focusing lens unit 16 is formed in the center of the entire lens and has a concave shape to focus light to the center.

즉, 반사면(17)이 중심을 향하여 경사진 형상을 갖는다. 따라서, 광원(14)에서 발생한 광은 이 반사면(17)을 통과하면서 직진방향으로 전환된다.That is, the reflective surface 17 has a shape inclined toward the center. Accordingly, the light generated from the light source 14 passes through the reflective surface 17 and is converted in a straight direction.

통상 광이 투명재질의 판상체에 90도 각도로 입사되면 대부분은 판상체를 통과하여 직진하게 된다.Usually, when light is incident on a plate-shaped body of a transparent material at an angle of 90 degrees, most of it passes through the plate-shaped body and goes straight.

반면에, 판상체가 경사지는 경우, 이러한 판상체에 광이 입사되면 광은 표면에서 대부분 반사된다.On the other hand, when the plate body is inclined, when light is incident on the plate body, the light is mostly reflected from the surface.

이러한 원리로 인하여, 광원(14)에서 반사면(17)으로 조사된 광은 반사면(17)이 경사진 형상이므로 반사면(17)에서 렌즈의 내측으로 반사됨으로써 확산 렌즈부(18)로 입사된다.Due to this principle, the light irradiated from the light source 14 to the reflective surface 17 is incident on the diffusion lens unit 18 by being reflected from the reflective surface 17 to the inside of the lens because the reflective surface 17 has an inclined shape. do.

한편, 상기 초점 렌즈부(10)는 도 3에 도시된 형상에 한정되는 것이 아니라, 다른 형상으로 변형하여 실시가능한 바, 그 일예로서 도 4에 도시된 형상으로도 가능하다.On the other hand, the focus lens unit 10 is not limited to the shape shown in FIG. 3 , but may be deformed into another shape and may be implemented in the shape shown in FIG. 4 as an example thereof.

즉, 렌즈표면에서 일정 깊이로 오목부(19)가 형성되고, 오목부(19)의 바닥에 경사면(20)이 형성되는 구조이다.That is, the concave portion 19 is formed at a predetermined depth on the lens surface, and the inclined surface 20 is formed at the bottom of the concave portion 19 .

따라서, 광원(14)으로부터 발생된 광은 경사면(20)에 도달하며, 일부는 경사면(20)을 관통하여 직진하게 되고, 다른 광은 경사면(20)에서 반사되어 주위의 확산 렌즈부(18)로 확산된다.Accordingly, the light generated from the light source 14 reaches the inclined surface 20, some of it passes through the inclined surface 20 and goes straight, and the other light is reflected from the inclined surface 20 to the surrounding diffusion lens unit 18. spread to

이러한 확산 렌즈부(18)는 렌즈부(10)의 전방에 배치되며 중심의 반사면(17)에서 외주방향으로 연장 형성된 전방 렌즈면(21)과; 렌즈부(10)의 후방에 경사방향으로 배치되며 계단형상으로 형성되는 후방 렌즈면(22)을 포함한다.The diffusion lens unit 18 is disposed in front of the lens unit 10 and includes a front lens surface 21 extending from the central reflective surface 17 in the outer circumferential direction; It is disposed in an oblique direction at the rear of the lens unit 10 and includes a rear lens surface 22 formed in a step shape.

전방 렌즈면(21)은 편평한 형상이며, 기판(12)과 나란한 방향으로 형성된다. 따라서, 광원(14)에서 발생된 광을 전방으로 조사하게 된다.The front lens surface 21 has a flat shape and is formed in a direction parallel to the substrate 12 . Accordingly, the light generated from the light source 14 is irradiated forward.

그리고, 전방 렌즈면(21) 및 촛점 렌즈부(16)에서 반사되어 내측으로 조사된 광은 후방 렌즈면(22)에 의하여 반사된 후 전방으로 조사된다.Then, the light reflected by the front lens surface 21 and the focusing lens unit 16 and irradiated to the inside is reflected by the rear lens surface 22 and then irradiated to the front.

후방 렌즈면(22)은 중심에서 양측 상향으로 경사진 형상을 갖는다. 그리고, 경사면(20)에는 다수개의 계단이 형성된다.The rear lens surface 22 has a shape inclined upward at both sides from the center. In addition, a plurality of steps are formed on the inclined surface 20 .

따라서, 광이 다수개의 계단에서 반사됨으로써 렌즈부(10)의 전방으로 조사될 수 있다.Accordingly, light may be irradiated to the front of the lens unit 10 by being reflected in a plurality of steps.

이때, 전방 렌즈면(21)에는 강한 직진 광이 조사되고, 경사면(20)에는 상대적으로 약한 직진 광이 조사될 수 있다.In this case, a strong straight light may be irradiated to the front lens surface 21 , and a relatively weak straight light may be irradiated to the inclined surface 20 .

이와 같이, 본 발명의 렌즈부(10)는 계단과 같이 각도에 의하여 광을 반사하게 되므로 광 반사를 위한 도금이 불필요하다. 또한, 화소당 반사면(17)적이 최대로 확장될 수 있다. 그리고, 렌즈 단면이 슬림화될 수 있다.As described above, since the lens unit 10 of the present invention reflects light by an angle like a staircase, plating for light reflection is unnecessary. In addition, the area of the reflective surface 17 per pixel can be maximized. In addition, the lens cross-section may be slimmed down.

또한, 후방 렌즈면(22)의 경사각을 조절함으로써 광의 반사각도를 쉽게 조절할 수 있어서 차량의 전조등에 적용할 수 있다.In addition, by adjusting the angle of inclination of the rear lens surface 22, the angle of reflection of light can be easily adjusted, so that it can be applied to the headlamp of a vehicle.

그리고, 광원(14) 주위에 홈(h)을 형성함으로써 광을 1차적으로 반사 및 집중함으로써 전방으로 조사할 수 있다.And, by forming the groove h around the light source 14, the light can be irradiated forward by primarily reflecting and concentrating the light.

이때, 홈(h)의 깊이가 깊을수록, 예를 들면 광원의 높이 보다 3배 이상의 홈깊이인 경우 광을 중심에 집중하기 유리하고, 얕을 수록(그 이하의 홈 깊이일 수록) 사방으로 퍼지게 된다.At this time, the deeper the depth of the groove (h), for example, if the groove depth is three times or more than the height of the light source, it is advantageous to focus the light to the center, and the shallower (the lower the groove depth), the more it spreads in all directions. do.

한편, 본 발명의 다른 실시예로서, 렌즈부(10)의 형상을 다양하게 변경할 수 있다.Meanwhile, as another embodiment of the present invention, the shape of the lens unit 10 may be variously changed.

예를 들면, 도 5(a),(b),(c)에 도시된 바와 같이, 촛점 렌즈부(16)와 확산 렌즈부(18)의 형상을 정면에서 볼 때(광원의 조사방향과 반대 방향), 원형으로 하거나, 혹은 사각형상으로 변경하거나, 타원형상, 다각형상으로 변경하거나, 이러한 원형, 사각형, 타원, 다각 형상이 중심에서 외측 방향으로 복수개로 형성될 수도 있다. 혹은, 별형상 등 다양한 형상으로 변경할 수 있다.For example, as shown in Figs. 5(a), (b) and (c), when the shape of the focusing lens unit 16 and the diffusing lens unit 18 is viewed from the front (opposite to the irradiation direction of the light source) direction), a circular shape, a rectangular shape, an elliptical shape, a polygonal shape, or a plurality of such circular, rectangular, elliptical, and polygonal shapes may be formed from the center to the outside. Alternatively, it can be changed to various shapes such as a star shape.

그리고, 상기 사출물(5)은 투명한 재질로 형성되며, 내측에 공간이 형성된다. 따라서, 사출물(5)을 프레임(3)상에 고정하는 경우, 사물출의 내측에 렌즈부(10)가 배치될 수 있다. And, the injection-molded product 5 is formed of a transparent material, and a space is formed inside. Accordingly, when the injection molding 5 is fixed on the frame 3 , the lens unit 10 may be disposed on the inside of the object projection.

이와 같이, 투명한 재질의 사출물(5)이 렌즈부(10)의 외부를 감싸는 형태로 배치되므로 발광시 광이 렌즈부(10)를 통화한 후 이 사출물(5)을 통하여 외부로 조사될 수 있다.In this way, since the transparent material 5 is disposed to surround the outside of the lens unit 10, light can be irradiated to the outside through the injection product 5 after the light passes through the lens unit 10 when emitting light. .

한편, 본 발명의 전조등 조립체(1)에는 방열부를 장착할 수도 있는 바, 차량의 램프를 구성하는 베젤 혹은 하우징 등에 방열부를 장착됨으로써 열을 방열한다.On the other hand, the headlight assembly 1 of the present invention may be equipped with a heat dissipation unit, and the heat dissipation unit is mounted on the bezel or housing constituting the lamp of the vehicle to dissipate heat.

상기한 바와 같은 전조등 조립체(1)는 다양한 분야에 적용될 수 있는 바, 예를 들면, 전조등, 주간 주행등, 미등에 적용될 수 있다.The headlight assembly 1 as described above can be applied to various fields, for example, it can be applied to a headlight, a daytime running light, and a tail light.
