간접 조명방식의 차량용 램프{Indirect illumination lamp for automobile}Indirect illumination lamp for automobile

본 발명은 간접 조명방식의 차량용 램프에 관한 것으로서, 더욱 상세하게는 LED 소자와 2개의 리플렉터를 조합하여 만든 간접 조명방식의 램프를 제공함으로써, 벌브의 삭제에 따른 내열성능의 향상으로 램프의 전체적인 크기를 축소할 수 있으며, 이에 따라 트렁크나 리어 패키지의 충분한 공간을 확보할 수 있도록 한 간접 조명방식의 차량용 램프에 관한 것이다.The present invention relates to an indirect lighting vehicle lamp, and more particularly, by providing an indirect lighting lamp made by combining an LED element and two reflectors, the overall size of the lamp by improving the heat resistance according to the elimination of the bulb It can be reduced, and thus relates to a vehicle lamp of the indirect lighting system to ensure a sufficient space of the trunk or rear package.

일반적으로 차량용 램프는 도 1 내지 도 3에 도시한 바와 같이 벌브(10), 리플렉터(11), 렌즈(12), 하우징(13) 등으로 구성되어 있다.Generally, a vehicle lamp is composed of a bulb 10, a reflector 11, a lens 12, a housing 13, and the like, as shown in FIGS. 1 to 3.

이러한 벌브 타입의 램프는 벌브를 기준으로 포물선 방정식(Y2=4fX)의 포커스를 갖는 리플렉터, 하우징, 렌즈로 구성되어 있는데, 기본적인 포커스(벌브의 중심에서 리플렉터까지 거리)와 벌브 내열거리로 인하여 램프의 깊이가 깊어지므로, 트렁크측의 레이아웃이 불리해지는 경향이 많을 뿐만 아니라 트렁크 및 리어 패키지의 공간 확보에도 불리한 단점이 있으며, 램프와 패널 간의 구성관계도 복잡해져 디자인 스타일링에 맞는 램프를 구성하기 힘들어지는 단점이 있다.The bulb-type lamp is composed of a reflector, a housing, and a lens having a focus of a parabolic equation (Y 2 = 4fX) in relation to the bulb. The deeper the depth of the trunk, the more the layout of the trunk side tends to be disadvantageous, and the disadvantage of securing space in the trunk and rear packages is also disadvantageous, and the composition relationship between the lamp and the panel is complicated, making it difficult to construct a lamp suitable for design styling There is this.

따라서, 본 발명은 이와 같은 점을 감안하여 안출한 것으로서, 램프의 크기 및 내열관계에 영향을 미치는 기존의 벌브 및 하우징을 배제하고, 벌브를 대신할 수 있는 LED 소자와 하우징의 역할도 겸할 수 있는 2개의 리플렉터를 조합시킨 새로운 개념의 램프 시스템을 제공함으로써, 벌브 등의 삭제에 따른 내열성능의 향상으로 램프의 전체적인 크기를 축소할 수 있는 동시에 이에 따른 트렁크나 리어 패키지의 충분한 공간 확보를 도모할 수 있고, LED 소자의 적용으로 대향차 및 후방차의 시인속도 증대로 안전성 및 편의성을 향상시킬 수 있도록 하는데 그 안출의 목적이 있는 것이다.Accordingly, the present invention has been made in view of the above, and excludes the existing bulbs and housings affecting the size and heat resistance of the lamp, and can also serve as an LED element and housing that can replace the bulb. By providing a new concept of lamp system combining two reflectors, it is possible to reduce the overall size of the lamp by improving heat resistance due to elimination of bulbs, etc., while at the same time ensuring sufficient space in the trunk or rear package. In addition, the application of the LED element to improve the safety and convenience by increasing the viewing speed of the opposite car and the rear car is the purpose of the design.

It is done.

또한, 상기 제2리플렉터(16)의 반사면은 렌즈(12)의 반사면과 서로 대향관계를 가지면서 빛의 상하 확산을 가능하도록 한 것을 특징으로 한다.In addition, the reflective surface of the second reflector 16 is characterized in that it is possible to vertically diffuse the light while having a mutual relationship with the reflective surface of the lens 12.

또한, 상기 각각의 제1리플렉터(15) 및 LED 소자(14)는 좌우 동일한 수의 대칭구조로 배치되는 것을 특징으로 한다.In addition, each of the first reflector 15 and the LED element 14 is characterized in that arranged in the same number of symmetrical structure.

이를 좀더 상세히 설명하면 다음과 같다.This will be described in more detail as follows.

본 발명의 램프는 전면의 렌즈(12)와, 하우징 및 리플렉터의 역할을 위한 제2리플렉터(16)와, 벌브의 역할을 위한 세트형태의 제1리플렉터(15) 및 LED 소자(14)로 구성된다.The lamp of the present invention comprises a lens 12 on the front surface, a second reflector 16 for the role of the housing and the reflector, a first reflector 15 and the LED element 14 in the form of a set for the role of the bulb. do.

상기 제2리플렉터(16)는 렌즈(12)와 동일한 곡률을 갖는 판형으로 되어 있으며, 렌즈(12)의 뒷쪽에 조립되면 도 5에서 볼 수 있는 바와 같이 렌즈(12)와 함께 얄팍한 사각박스형 구조를 이룰 수 있게 된다.The second reflector 16 has a plate shape having the same curvature as that of the lens 12. When the second reflector 16 is assembled to the rear side of the lens 12, the second reflector 16 has a thin rectangular box structure together with the lens 12 as shown in FIG. 5. It can be achieved.

즉, 종전과 같이 안쪽으로 깊게 연장되는 하우징과는 달리 내부에 광원의 설치를 위한 최소한의 공간만을 남겨둔 상태로 전후 폭을 최대한 얇게 만들 수 있다.That is, unlike the housing that extends inwardly as before, the front and rear widths can be made as thin as possible while leaving only a minimum space for installing the light source therein.

또한, 도 6에 도시한 바와 같이 제2리플렉터(16)의 전면 반사면은 렌즈(12)의 반사면과 대향되는 형태로 되어 있으며, 이러한 반사면을 통해 빛을 상하 및 좌우방향으로 확산시켜줄 수 있게 된다.In addition, as shown in FIG. 6, the front reflecting surface of the second reflector 16 is formed to face the reflecting surface of the lens 12, and the light reflects the light in the vertical direction. Will be.

상기 제2리플렉터(16)는 렌즈(12)와 전체 둘레에 걸쳐 끼워지는 방식으로 조립될 수 있으며, 스크류 체결을 통해 렌즈(12)와 함께 패널상에 고정되는 구조로 설치될 수 있게 된다.The second reflector 16 may be assembled in such a manner that the second reflector 16 is fitted over the entire circumference of the lens 12 and may be installed in a structure fixed to the panel together with the lens 12 by screwing.

상기 제1리플렉터(15)는 대략 "ㄱ" 자 형태로 이루어진 단위 조각으로 되어 있으며, 한쪽면은 LED 소자(14)의 설치를 위해 사용되고, 나머지 한쪽면은 반사면으로 사용된다.The first reflector 15 is formed in a unit piece having a substantially "a" shape, one side of which is used for installation of the LED element 14, and the other side of which is used as a reflective surface.

이때의 반사면은 제2리플렉터(16)의 반사면을 마주볼 수 있도록 구성되어LED 소자(14)의 빛을 받아 제2리플렉터(16)의 반사면으로 반사할 수 있게 된다.At this time, the reflecting surface is configured to face the reflecting surface of the second reflector 16 to receive the light of the LED element 14 to reflect to the reflecting surface of the second reflector 16.

상기 LED 소자(14)는 각 제1리플렉터(15)에 1개씩 배속되는 동시에 제1리플렉터(15)의 한쪽 측면에서 그 반사면을 향하는 자세로 통상적인 접착수단에 의해 부착 설치된다.The LED elements 14 are attached to each of the first reflectors 15 one by one, and are attached to the first reflector 15 by conventional bonding means in a position facing the reflective surface on one side of the first reflector 15.

이러한 제1리플렉터(15)와 LED 소자(14)는 도 3에서 볼 수 있는 바와 같이 좌우측에서 위아래 일렬로 배치되며, 제2리플렉터(16)의 안쪽면에 일체식으로 고정되는 구조로 설치될 수 있게 된다.As shown in FIG. 3, the first reflector 15 and the LED element 14 may be arranged in a line up and down from left and right, and may be installed in a structure fixed to the inner surface of the second reflector 16. Will be.

따라서, 소정의 스위치 신호, 예를 들면 미등 신호나 브레이크 신호에 의해 LED 소자가 발광되면 이때의 빛은 제1리플렉터의 반사면을 통해 제2리플렉터의 반사면으로 반사되고, 이러한 간접 조명은 제2리플렉터의 반사면에 의해 상하 및 좌우로 확산되면서 전방으로 조사된다.Therefore, when the LED element emits light by a predetermined switch signal, for example, a taillight signal or a brake signal, the light at this time is reflected through the reflection surface of the first reflector to the reflection surface of the second reflector, and such indirect illumination Irradiated forward while spreading up and down and left and right by the reflecting surface of the reflector.

이와 같은 본 발명의 램프는 차량 후방에 설치되는 리어 콤비네이션 램프에 적용하는 것이 바람직하며, 특히 LED 소자의 채용으로 브레이크 작동시 램프의 온 속도를 증대시킬 수 있어 대향차 및 후방차의 시인성을 향상시킬 수 있다.Such a lamp of the present invention is preferably applied to the rear combination lamp installed in the rear of the vehicle, and in particular, the adoption of the LED element can increase the on-speed of the lamp during brake operation to improve the visibility of the opposite and rear cars Can be.

또한, 기존의 벌브 및 벌브 홀더 등을 삭제하여 부품수를 대폭 줄여 램프의 경량화에 일조할 수 있으며, 무엇보다도 내열성능의 문제로 램프 크기를 크게 할 필요가 없게 되므로, 램프의 전체적인 크기를 줄일 수 있어 그 안쪽의 트렁크나 리어 패키지의 공간을 크기가 줄어든 만큼 충분하게 확보할 수 있다.In addition, by eliminating existing bulbs and bulb holders, the number of parts can be greatly reduced, which contributes to lightening the lamp. The space on the inside of the trunk and rear package can be secured as the size is reduced.

또한, 이렇게 램프를 콤팩트하게 구성할 수 있고, 이에 따라 램프의 제작과 관련한 설계자유도를 높일 수 있게 되므로, 디자인 스타이링을 극대화 할 수 있다.In addition, the lamp can be compactly configured in this way, and thus the design freedom associated with the manufacture of the lamp can be increased, thereby maximizing the design styling.

이상에서와 같이 본 발명은 LED 소자와 2개의 리플렉터를 조합하여 만든 간접 조명방식의 램프를 제공함으로써, 벌브의 삭제에 따른 내열성능의 향상으로 램프의 전체적인 크기를 축소할 수 있는 장점이 있으며, 이에 따라 트렁크나 리어 패키지의 충분한 공간을 확보할 수 있는 효과가 있는 것이다.As described above, the present invention provides an indirect lighting lamp made by combining an LED element and two reflectors, and has an advantage of reducing the overall size of the lamp by improving heat resistance according to the elimination of bulbs. Therefore, it is effective to secure sufficient space of the trunk or rear package.
