Field of the Invention The present invention relates to a structure for preventing color separation and a headlamp for a transportation machine using the same, and more particularly, to a structure having a function of preventing color separation phenomenon occurring in a headlamp structure for a transporting vehicle will be.

종래 차량용 전조등에 관한 기술과 관련해서는, 한국공개특허 제10-2006-0046626호(이하, '선행문헌') 외에 다수 공개 및 등록되어 있다. Related to the technology related to the conventional vehicle headlamps, there are a lot of other publications and registered in addition to Korean Patent Laid-Open No. 10-2006-0046626 (hereinafter referred to as "prior literature").

상기한 선행문헌은, 라이트 빔(beam)의 상부 영역에 컷오프를 갖는 상기 라이트 빔을 제조하도록 의도된 자동차용 헤드라이트에 있어서, 타원형 타입의 반사기와, 실질적으로 상기 반사기의 제 1 초점에 위치된 광원과, 물체 초점이 상기 반사기의 제 2 초점에 근접하게 위치되는 수렴 광학 수단과, 상기 반사기의 제 2 초점 부근에 위치되고 실질적으로 수평방향 상부 에지를 갖는 헤드라이트의 광학 축에 횡방향으로 배향된 제 1 쉴드와, 상기 제 1 쉴드에 실질적으로 평행하지만 상기 광학 수단에 보다 근접하게 위치되도록 상기 광학 축을 따라 편위된 제 2 쉴드를 포함하며, 상기 쉴드는 상기 헤드라이트의 광선에 컷오프를 형성하여 훈색 현상을 제한하며, 상기 제 2 쉴드는 실질적으로 V자 또는 U자 형상으로 횡방향 섹션을 갖는 단일 부재로 조립체를 형성하기 위해서 상기 제 1 쉴드에 고정되며, V자 또는 U자 형상 섹션의 2개의 아암이 상기 2개의 쉴드에 대응하는 것을 특징으로 한다. The foregoing prior art document discloses an automotive headlight intended to produce the light beam with a cutoff in the upper region of the light beam, the headlight comprising an elliptical type of reflector and a reflector positioned substantially at the first focus of the reflector A converging optical means in which an object focus is located close to a second focus of the reflector and a second focus of the reflector in a direction transverse to the optical axis of the headlight positioned near the second focus of the reflector and having a substantially horizontal upper edge, And a second shield which is substantially parallel to the first shield but is displaced along the optical axis so as to be positioned closer to the optical means, the shield forming a cutoff in the light beam of the headlight Wherein the second shield is a single member having a substantially V-shaped or U-shaped transverse section, In order to be secured to said first shield, characterized in that the two arms of the V-shaped or U-shaped section corresponding to the two shields.

종래의 일반적인 수송기기용 전조등에 사용되는 엘이디는 청색 칩에 yellow 형광체가 도포된 봉지재로 봉지하였다. Conventionally, an LED used in a headlight for a general transportation machine is encapsulated with a yellow chip-coated encapsulant.

이에 따라, 도 1 에 도시된 바와 같이, 광원의 렌즈 투과 시 색수차로 인한 색번짐이 발생하였다. As a result, as shown in FIG. 1, color casting due to chromatic aberration occurred during lens transmission of the light source.

이때, 색수차란 빛이 렌즈를 투과할 때 렌즈의 굴절률이 파장에 의존적임으로 생기는 현상으로서, 파장에 따른 굴절률은 도 2 에 도시된 바와 같다. 즉, 종래에는 광원에서 나온 빛이 컷-오프(cut off) 라인을 통과한 후 렌즈에 입사하게 되는데, 렌즈에서 색수차가 발생하여 색분리 현상이 발생하였다. At this time, the chromatic aberration is a phenomenon that occurs when the refractive index of the lens is dependent on the wavelength when the light passes through the lens, and the refractive index according to the wavelength is as shown in Fig. That is, conventionally, light emitted from a light source enters a lens after passing through a cut-off line, and chromatic aberration occurs in the lens, resulting in color separation phenomenon.

이러한 문제점을 극복하기 위하여, 렌즈에 패턴을 형성하여 색혼합을 수행하였으나, 형성된 패턴에 의해 빛의 손실 및 배광조절에 어려움이 발생하였다. In order to overcome this problem, color mixing was performed by forming a pattern on the lens, but it was difficult to control the light loss and the light distribution by the formed pattern.

It is to be noted that the detailed description of known functions and constructions related to the present invention is omitted when it is determined that the gist of the present invention may be unnecessarily blurred.

이하, 첨부된 도면을 참조하여 본 발명을 상세하게 설명한다. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will now be described in detail with reference to the accompanying drawings.

본 발명에 따른 색분리 현상 방지 구조 및 이를 이용한 수송기기용 전조등에 관하여 도 3 및 도 5 를 참조하여 설명하면 다음과 같다. The color separation preventing structure and the headlamp for a transporting machine using the same according to the present invention will now be described with reference to FIGS. 3 and 5. FIG.

도 3 은 본 발명에 따른 색분리 현상 방지 구조에 관한 전체 구성도로서, 도시된 바와 같이 광원(100), 리플렉터(200), 컷 오프 쉴드(300) 및 렌즈(400)를 포함하여 이루어진다.FIG. 3 is an overall view of the structure for preventing color separation according to the present invention, and includes a light source 100, a reflector 200, a cutoff shield 300, and a lens 400, as shown in FIG.

광원(100)은 청색 또는 UV 엘이디(LED)이다. The light source 100 is a blue or UV LED.

본 발명에서는, 백색 엘이디(LED)가 아닌 청색 또는 UV 엘이디(LED)를 광원(100)으로서 사용한다. In the present invention, a blue or UV LED (LED) other than a white LED is used as the light source 100.

리플렉터(200)는 타원형으로서 상기 광원(100)을 감싸도록 형성되어, 광원(100)으로부터 생성된 빛을 반사하여, 컷 오프 쉴드(300)로 포커싱(focusing)한다. The reflector 200 is formed to surround the light source 100 as an ellipse and reflects light generated from the light source 100 and focuses the light onto the cutoff shield 300.

컷 오프 쉴드(300)는 반사형 또는 셰이드(shade)형으로서, 상기 리플렉터(200)와 렌즈(400) 사이에 설치되어, 리플렉터(200)로부터 반사되는 빛의 일부를 반사한다. The cut-off shield 300 is of a reflection type or shade type and is provided between the reflector 200 and the lens 400 to reflect a part of light reflected from the reflector 200.

구체적으로, 컷 오프 쉴드(300)는 컷 오프(cut-off) 라인(line)을 가지고 있어, 상기 리플렉터(200)로부터 반사되는 빛의 일부를 반사시켜 컷 오프(cut-off) 라인(line) 패턴으로 차단한다. Specifically, the cut-off shield 300 has a cut-off line, and reflects a part of the light reflected from the reflector 200 to form a cut-off line, Pattern.

즉, 컷 오프 쉴드(300)는 상기 리플렉터(200)로부터 입사광의 일부를 차폐하는 것으로, 이를 통해 로우 빔용 패턴 또는 하이 빔용 패턴 등을 형성하도록 제어한다. That is, the cut-off shield 300 shields a part of the incident light from the reflector 200, and controls the low-beam pattern or the high-beam pattern to be formed through the shielding.

렌즈(400)는 상기 컷 오프 쉴드(300)를 통과하여 입사되는 빛을 평행광으로 변환하여 전방으로 확산시킨다. The lens 400 converts the incident light passing through the cutoff shield 300 into parallel light and diffuses it forward.

이때, 렌즈(400)는 그 자체 또는 표면에 형광체 코팅층(410) 또는 형광체 필름(420)이 형성되어 있어, 입사된 청색의 일부를 황색으로 변환시킨 후, 청색과 혼합시켜 백색 광으로 변환시킨다. At this time, the lens 400 has a phosphor coating layer 410 or a phosphor film 420 formed on its surface or on its surface so that a part of the incident blue color is converted into yellow, and then it is mixed with blue and converted into white light.

여기서, 형광체 코팅층(410) 또는 형광체 필름(420)은, 광원에 의해 여기되어 파장변환이 일어나는 형광체를 이용하여 백색 광으로 변환시킬 수 있는 형광체, 바람직하게 청색 또는 UV 엘이디용 황색 형광체를 사용한다.Here, the phosphor coating layer 410 or the phosphor film 420 uses a phosphor capable of being converted into white light by using a phosphor excited by a light source to cause wavelength conversion, preferably a blue phosphor or a yellow phosphor for UV LED.

즉, 형광체 코팅층(410) 또는 형광체 필름(420)은 광원에 의해 여기되어 파장변환이 일어남으로써, 상기 광원과 혼합되어 백색 광을 생성한다. That is, the phosphor coating layer 410 or the phosphor film 420 is excited by the light source to cause wavelength conversion, thereby mixing white light with the light source.

한편, 형광체 코팅층(410) 또는 형광체 필름(420)은 UV 엘이디용 청색, 녹색, 적색 형광체를 혼합하거나, UV 엘이디용 청색, 황색을 혼합하거나, 청색 엘이디용 황색, 적색을 혼합하여 사용할 수도 있다. The phosphor coating layer 410 or the phosphor film 420 may be used by mixing blue, green and red phosphors for UV LED, mixing blue and yellow for UV LED, or mixing yellow and red for blue LED.

본 실시예에서, 렌즈(400) 자체 또는 표면에 형광체 코팅층(410)이 형성된 것으로 설명하였으나, 본 발명이 이에 한정되지 않는 바, 도 4 에 도시된 바와 같이 전조등에서 렌즈(400) 이후의 커버렌즈(500)의 자체 또는 표면에 형광체 코팅층(410) 또는 형광체 필름(420)이 형성되거나, 도 5 에 도시된 바와 같이 렌즈(400)와 커버렌즈(500) 사이에서 기타 지지 구조물을 통해 형광체 코팅층(410) 및 형광체 구조물(420)이 형성될 수도 있다. 즉, 렌즈(400)의 상부 전방 방향으로 삽입된 것으로 어떤 형태로도 변경 가능하다. In the present embodiment, the lens 400 itself or the phosphor coating layer 410 is formed on the surface of the lens 400. However, the present invention is not limited thereto. As shown in FIG. 4, The phosphor coating layer 410 or the phosphor film 420 may be formed on the surface of the phosphor coating layer 500 or on the surface of the phosphor coating layer 410 or between the lens 400 and the cover lens 500 as shown in FIG. 410 and a phosphor structure 420 may be formed. That is, it is inserted in the upper front direction of the lens 400 and can be changed in any form.

한편, 본 발명에 따른 렌즈(400)는 유리, 및 PMMA, PC 등의 플라스틱 등의 재질일 수 있다. Meanwhile, the lens 400 according to the present invention may be made of glass, plastic such as PMMA, PC, or the like.

지금까지 상술한 바와 같은, 본 발명에 따른 색분리 현상 방지 구조는, 광원의 컷 오프 라인 통과에 따른 렌즈 투과 시 발생하던 색수차에 의한 색분리 현상을 제거할 수 있으며, 렌즈에 패턴을 형성하여 색혼합을 수행하지 않아도 되며, 차량과 같은 수송기기용 전조등으로 사용가능한 특징적인 장점을 가진다. The color separation preventing structure according to the present invention as described above can eliminate the color separation phenomenon due to the chromatic aberration which occurs when the lens passes through the cutoff line of the light source, There is no need to perform mixing, and it has a characteristic advantage that it can be used as a headlight for a transportation machine such as a vehicle.
