도 1은 본 발명에 따른 자동차의 조명 장치에 포함된 광원부를 나타낸 사시도이고, 도 2는 도 1에 나타낸 광원부를 나타낸 분해 사시도이고, 도 3은 도 1에 나타낸 광원부를 상부에서 바라본 상면도이다.1 is a perspective view showing a light source unit included in a lighting apparatus of a vehicle according to the present invention, FIG. 2 is an exploded perspective view showing the light source unit shown in FIG. 1, and FIG. 3 is a top view of the light source unit shown in FIG.

도 1 내지 도 3을 참조하면, 광원부(100)는 인쇄회로기판(110), 인쇄회로기판(110)에 실장된 제1, 2 LED 소자(120, 130) 및 인쇄회로기판(110) 상에 형성되며 제1, 2 LED 소자(120, 130)를 밀봉하는 라이트 가이드(140)를 포함할 수 있다.1 to 3, the light source unit 100 is disposed on the printed circuit board 110, the first and second LED devices 120 and 130 mounted on the printed circuit board 110, and the printed circuit board 110. The light guide 140 may be formed to seal the first and second LED devices 120 and 130.

여기서, 인쇄회로기판(110)은 FR4 재질로 이루어진 PCB(Printed circuit board), 금속 재질로 이루어진 McPCB(Metal core printed circuit board) 및 필름 재질로 이루어지며 자유자재로 휘어질 수 있는 FPCB(Flexabe printed circuit board) 중 어느 하나일 수 있으며, 이 외에 다른 재질로 이루어진 PCB일 수 있으며 이에 한정을 두지 않는다.Here, the printed circuit board 110 is made of a printed circuit board (PCB) made of FR4 material, a metal core printed circuit board (MPCB) made of a metal material, and a film material, and may be flexibly printed FPCB (Flexabe printed circuit). board), in addition to the PCB may be made of other materials, without being limited thereto.

실시 예에서 인쇄회로기판(110)은 FR4 재질로 이루어진 PCB인 것으로 설명한다.In the embodiment, the printed circuit board 110 will be described as being a PCB made of FR4 material.

인쇄회로기판(110)은 베이스층(미도시), 상기 베이스층 상에 제1, 2 LED 소자(120, 130)가 실장되며, 전기적으로 연결된 동박층(미도시) 및 상기 동박층 상에 배치되며 상기 동박층이 외부로 노출되는 것을 방지하는 절연층(미도시)을 포함할 수 있다.The printed circuit board 110 includes a base layer (not shown), first and second LED devices 120 and 130 mounted on the base layer, and disposed on an electrically connected copper foil layer (not shown) and the copper foil layer. And an insulating layer (not shown) for preventing the copper foil layer from being exposed to the outside.

이때, 인쇄회로기판(110) 상에는 반사부재(150)가 배치될 수 있다.In this case, the reflective member 150 may be disposed on the printed circuit board 110.

여기서, 반사부재(150)는 상기 절연층일 수 있거나, 또는 상기 절연층 상에 배치되며, Ag 및 Al 중 적어도 하나를 포함하는 반사 필름이거나, 소정의 반사도를 갖는 PSR 잉크일 수 있으며, 이에 한정을 두지 않는다.Here, the reflective member 150 may be the insulating layer, or disposed on the insulating layer, and may be a reflective film containing at least one of Ag and Al, or may be a PSR ink having a predetermined reflectivity. Do not leave.

즉, 반사부재(150)는 제1, 2 LED 소자(120, 130)로부터 조사된 광을 라이트 가이드(140)의 적어도 두 방향으로 반사시킬 수 있다.That is, the reflective member 150 may reflect the light emitted from the first and second LED elements 120 and 130 in at least two directions of the light guide 140.

또한, 반사부재(150)의 표면에는 제1, 2 LED 소자(120, 130)에서 조사된 광을 라이트 가이드(140)의 상면 방향으로 반사시키는 반사패턴(미도시)이 형성될 수 있으며, 이에 한정을 두지 않는다.In addition, a reflective pattern (not shown) may be formed on the surface of the reflective member 150 to reflect the light emitted from the first and second LED elements 120 and 130 in the direction of the upper surface of the light guide 140. There is no limit.

이때, 제1, 2 LED 소자(120, 130)는 인쇄회로기판(110)의 서로 대응되는 제1, 2 측면부(미도시)에 배치될 수 있다.In this case, the first and second LED devices 120 and 130 may be disposed on the first and second side parts (not shown) of the printed circuit board 110.

여기서, 제1 LED 소자(120)는 인쇄회로기판(110)의 상기 제1 측면부에 실장되어 상기 제2 측면부 방향으로 광을 조사할 수 있으며, 이와 반대로 제2 LED 소자(130)는 인쇄회로기판(110)의 상기 제2 측면부에 실장되어 상기 제1 측면부 방향으로 광을 조사할 수 있다.Here, the first LED element 120 is mounted on the first side portion of the printed circuit board 110 to irradiate light toward the second side portion, on the contrary, the second LED element 130 is a printed circuit board The second side surface portion of the 110 may be mounted to irradiate light toward the first side surface portion.

결과적으로, 제1, 2 LED 소자(120, 130)는 서로 다른 방향, 즉 상기 제1 측면부에서 상기 제2 측면부 방향 및 상기 제2 측면부에서 상기 제1 측면부 방향으로 광을 조사할 수 있다.As a result, the first and second LED devices 120 and 130 may radiate light in different directions, that is, in the direction of the second side portion from the first side portion and in the direction of the first side portion from the second side portion.

이때, 제1, 2 LED 소자(120, 130)는 상기 제1, 2 측면부 방향을 기준으로 서로 비 중첩되게 인쇄회로기판(110)에 실장됨으로써, 서로 인접하게 실장된 제1, 2 LED 소자(120, 130) 사이로 광을 조사하여, 제1, 2 LED 소자(120, 130)에 의해 발생되는 암부를 최소화시킬 수 있다.In this case, the first and second LED elements 120 and 130 are mounted on the printed circuit board 110 so as to be non-overlapping with each other based on the direction of the first and second side portions, and thus, the first and second LED elements 120 and 130 are mounted adjacent to each other. By irradiating light between the 120 and 130, it is possible to minimize the dark portion generated by the first and second LED device (120, 130).

여기서, 반사부재(150)는 제1, 2 LED 소자(120, 130)에서 조사된 광을 라이트 가이드(140)의 상면 방향으로 반사시켜 광의 조사 방향을 조절할 수 있다.Here, the reflective member 150 may reflect the light irradiated from the first and second LED elements 120 and 130 in the upper surface direction of the light guide 140 to adjust the irradiation direction of the light.

제1, 2 LED 소자(120, 130)는 사이드 뷰 타입(side view type)의 패키지(package)일 수 있다.The first and second LED devices 120 and 130 may be packages of a side view type.

이때, 제1, 2 LED 소자(120, 130)는 사이드 뷰 타입의 패키지가 사용됨에 따라 반사부재(150)가 라이트 가이드(140)의 상면 방향으로 광의 방향을 변경할 수 있도록 할 수 있다.In this case, as the side view type package is used, the first and second LED devices 120 and 130 may allow the reflective member 150 to change the direction of light toward the upper surface of the light guide 140.

즉, 도 3에 나타낸 바와 같이, 제1 LED 소자(120)는 제1 범위(s1)로 광을 조사하며, 제2 LED 소자(130)는 제1 범위(s1)와 반대되는 방향으로 제2 범위(s2)로 광을 조사함에 따라 라이트 가이드(140)의 전체 영역에 균일한 광을 제공할 수 있다.That is, as shown in FIG. 3, the first LED element 120 irradiates light in the first range s1, and the second LED element 130 is second in the direction opposite to the first range s1. As the light is irradiated in the range s2, uniform light may be provided to the entire area of the light guide 140.

라이트 가이드(140)는 인쇄회로기판(110) 상에 형성되며, 제1, 2 LED 소자(120, 130)를 밀봉 또는 매몰할 수 있다.The light guide 140 is formed on the printed circuit board 110 and may seal or bury the first and second LED elements 120 and 130.

즉, 라이트 가이드(140)는 제1, 2 LED 소자(120, 130)에서 조사된 광을 상면 및 측면 중 적어도 한 면, 또는 적어도 두 방향으로 방출하는 광학 레진(resin)일 수 있으며, 이에 한정을 두지 않는다.That is, the light guide 140 may be an optical resin that emits light emitted from the first and second LED devices 120 and 130 in at least one of the top and side surfaces, or in at least two directions. Do not put

라이트 가이드(140)는 인쇄회로기판(140) 상에 제1, 2 LED 소자(120, 130)를 실장한 후, 액화된 광학 레진을 밀봉하여 형성할 수 있으며, 렌즈 타입으로 형성될 수 있으며, 이에 한정을 두지 않는다.The light guide 140 may be formed by sealing the liquefied optical resin after mounting the first and second LED devices 120 and 130 on the printed circuit board 140, and may be formed as a lens type. There is no limitation to this.

라이트 가이드(140)는 제1, 2 LED 소자(120, 130)와 사이에 공간을 최소화시킬 수 있도록 형성되는 것이 가장 바람직할 것이다.The light guide 140 may be most preferably formed to minimize the space between the first and second LED devices 120 and 130.

이와 같이, 본 발명에 따른 자동차의 조명 장치는 사이드 뷰 타입의 패키지로 이루어진 제1, 2 LED 소자를 인쇄회로기판에 실장한 후, 라이트 가이드(140)에 밀봉되도록 함으로써, 라이트 가이드(140)의 전체 영역으로 광이 조사됨에 따라 광량 및 광 효율을 증대시킬 수 있는 이점이 있다.As described above, the lighting apparatus of the vehicle according to the present invention mounts the first and second LED elements of the side view type package on the printed circuit board, and then seals the light guide 140. As light is irradiated to the entire region, there is an advantage of increasing the amount of light and light efficiency.
