Description

램프유닛Lamp unit

본 발명은 램프유닛에 관한 것으로서, 더 상세하게는 곡률을 갖는 차량의 일측면에 장착될 때, 램프에서 발광하는 빛의 조사방향이 일정할 수 있도록 형성된 램프유닛에 관한 것이다.The present invention relates to a lamp unit, and more particularly, when mounted on one side of a vehicle having a curvature, relates to a lamp unit formed so that the irradiation direction of the light emitted from the lamp can be constant.

차량의 전방 및 후방에는 야간에 운전자의 시인성 확보를 위한 전조등과, 외부에서 차량의 주행상태, 주행 방향을 인식할 수 있도록 표시해주는 정지등과 방향 지시등이 마련되어 있다.The front and rear of the vehicle is provided with a headlight for securing the driver's visibility at night, and a stop light and a direction indicator for displaying the driving state and driving direction of the vehicle from the outside.

이러한 램프유닛은 차량의 안전운행과 매우 밀접한 관련이 있기 때문에 주행하는 차량과 인접한 차량의 운전자가 발광 상태를 명확하게 식별할 수 있도록 하는 것이 매우 중요하다.Since the lamp unit is very closely related to the safe driving of the vehicle, it is very important to enable the driver of the vehicle adjacent to the driving vehicle to clearly identify the light emission state.

최근에는 차량이 심미성을 높이고 공기저항을 줄일 수 있도록 차체의 측면과 후방의 연결부분이 곡률을 이루도록 제작되는 경우가 많다. 따라서 차체에 설치되는 램프유닛 역시 곡률을 이루는 차체에 설치될 수 있도록 차체의 곡률에 대응하는 곡률을 갖도록 제작되어야 하는데, 이 경우 램프유닛에 설치되는 발광램프에서 조사되는 빛의 조사 방향이 차량의 후방을 향하지 못하고, 곡률을 따라 차체의 측면을 향해 빛이 조사되도록 발광램프가 설치되어 모든 발광램프가 차량의 후방 또는 전방을 향해 빛이 조사되지 못하므로 인접한 차량 운전자가 점등 여부의 식별성이 저하되는 문제가 있다.Recently, in order to enhance aesthetics and reduce air resistance, the connection parts of the side and rear of the vehicle body are often made to have a curvature. Therefore, the lamp unit installed in the vehicle body should also be manufactured to have a curvature corresponding to the curvature of the vehicle body so that it can be installed on the vehicle body forming the curvature, in which case the direction of irradiation of light emitted from the light emitting lamps installed in the lamp unit is rear of the vehicle. The light emitting lamp is installed so that the light is irradiated toward the side of the vehicle along the curvature so that all light emitting lamps are not irradiated toward the rear or the front of the vehicle. There is.

따라서 곡률을 이루는 차체에 설치되더라도 발광램프에서 발광하는 빛의 조사방향이 전방 또는 후방의 차량 운전자에게 명확하게 인식될 수 있도록 일정한 조사방향을 갖게 램프유닛이 형성될 필요성이 있다.Therefore, it is necessary to form a lamp unit having a constant irradiation direction so that the irradiation direction of the light emitted from the light emitting lamp can be clearly recognized by the vehicle driver of the front or rear, even if installed in the curvature of the vehicle body.

본 발명은 상기 문제점을 해결하기 위한 것으로서, 램프가 장착되는 기판을 장착대상 차량에 단차지게 장착할 수 있도록 절곡된 상태로 용이하게 유지시킬 수 있게 형성된 램프유닛을 제공하는데 그 목적이 있다.SUMMARY OF THE INVENTION The present invention has been made in view of the above-described problem, and an object thereof is to provide a lamp unit which can be easily maintained in a bent state so that a substrate on which a lamp is mounted can be mounted stepwise on a target vehicle.

상기 목적을 달성하기 위한 본 발명에 따른 램프유닛은 플랙시블한 베이스부재와, 상기 베이스부재에 설치되어 전류가 흐를 수 있는 도전 패턴을 형성하며, 상기 베이스부재의 절곡시 절곡 형상을 유지하는 도전성 패턴층과, 상기 도전성 패턴층에 장착되어 인가되는 전류를 통해 발광하는 발광램프를 구비한다.The lamp unit according to the present invention for achieving the above object is a flexible base member, and a conductive pattern installed on the base member to form a conductive pattern through which current can flow, and maintains a bent shape when the base member is bent And a light emitting lamp that emits light through a current applied to the conductive pattern layer.

이하, 첨부된 도면을 참조하여 본 발명에 따른 램프유닛을 더욱 상세하게 설명하면 다음과 같다.Hereinafter, with reference to the accompanying drawings will be described in more detail the lamp unit according to the present invention.

도 1은 본 발명에 따른 램프유닛이 차량의 후방램프(10)를 구성하도록 설치된 상태를 도시한 측면도이다.1 is a side view illustrating a state in which a lamp unit according to the present invention is installed to constitute a rear lamp 10 of a vehicle.

도시된 바와 같이 차량의 후방램프(10)가 소정의 곡률을 갖도록 형성되는 경우에도 차량의 후방을 향해 엘이디램프(20)의 광이 조사될 수 있도록 하우징(30)의 내부에서 램프유닛(40)을 지지하는 체결부(50)가 단차지게 형성되어 있다.As illustrated, even when the rear lamp 10 of the vehicle is formed to have a predetermined curvature, the lamp unit 40 is provided inside the housing 30 so that light of the LED lamp 20 can be irradiated toward the rear of the vehicle. Fastening portion 50 for supporting the step is formed.

따라서 램프유닛(40) 역시 단차진 체결부(50)의 구조에 대응하도록 절곡 가능하게 형성되어야 하므로 본 발명의 램프유닛(40)은 절곡 가능하며, 절곡된 형상을 유지할 수 있도록 형성될 필요가 있다.Therefore, since the lamp unit 40 must also be formed to be bent to correspond to the structure of the stepped fastening portion 50, the lamp unit 40 of the present invention needs to be bent and formed to maintain the bent shape. .

도 2 및 도 3에는 도 1에 도시된 것처럼 단차진 체결부에 장착 가능하도록 절곡 및 형상 유지가 가능한 본 발명에 따른 램프유닛(100)의 제1 실시예가 도시되어 있다.2 and 3 illustrate a first embodiment of the lamp unit 100 according to the present invention that can be bent and maintained in shape so as to be mounted on the stepped fastening portion as shown in FIG. 1.

본 실시예의 램프유닛(100)은 베이스부재(110)와, 베이스부재(110)의 상면에 형성되는 도전성 패턴층(120)과, 도전성 패턴층(120)에 표면실장되는 발광램프(130)를 포함한다.The lamp unit 100 according to the present embodiment includes a base member 110, a conductive pattern layer 120 formed on an upper surface of the base member 110, and a light emitting lamp 130 mounted on the conductive pattern layer 120. Include.

상기 베이스부재(110)는 플렉시블한 합성수지재이며, 플렉시블하기 때문에 도 1의 체결부와 같이 단차지거나 소정각도 절곡된 형태의 장착대상물의 형상에 따라 용이하게 형태를 변형할 수 있다. 베이스부재(110)에는 베이스부재(110)를 장착대상물에 고정하기 위한 고정부(111)가 마련되어 있고, 필요에 따라 복수개의 베이스부재(110)를 상호 연결하기 위한 연결부(112)가 일측에 형성되어 있다.Since the base member 110 is a flexible synthetic resin material and is flexible, the shape of the base member 110 can be easily changed according to the shape of the mounting object, which is stepped or bent at a predetermined angle as shown in the fastening part of FIG. 1. The base member 110 is provided with a fixing portion 111 for fixing the base member 110 to the mounting object, and a connecting portion 112 for interconnecting the plurality of base members 110 is formed on one side as necessary. It is.

도전성 패턴층(120)은 베이스부재(110)의 상부에 형성되는 것으로서, 발광램프(130)에 인가되는 전류를 통전하기 위한 것이다.The conductive pattern layer 120 is formed on the base member 110 and is for energizing the current applied to the light emitting lamp 130.

본 실시예의 도전성 패턴층(120)은 동박이며, 발광램프(130)에 인가되는 전류의 통전 외에도 베이스부재(110)의 절곡된 형태를 고정하는 역할을 한다.The conductive pattern layer 120 of the present embodiment is copper foil, and serves to fix the bent shape of the base member 110 in addition to the energization of the current applied to the light emitting lamp 130.

상기 도전성 패턴층(120)의 두께는 30 내지 80㎛로 형성되는 것이 바람직하다.The thickness of the conductive pattern layer 120 is preferably formed to 30 to 80㎛.

도전성 패턴층(120)의 두께가 30㎛ 미만인 경우에는 도전성 패턴층(120)에 의한 베이스부재(110)의 형 고정력이 부족하여, 베이스부재(110)가 절곡된 형태로 유지되지 못하는 문제점이 있다.When the thickness of the conductive pattern layer 120 is less than 30 μm, there is a problem in that the base member 110 is not bent in a bent form due to a lack of mold holding force of the base member 110 by the conductive pattern layer 120. .

도전성 패턴층(120)의 두께가 두꺼워질수록 베이스부재(110)의 절곡 형상을 유지하는 형고정력이 증가하게 되지만 도전성 패턴층(120)이 80㎛를 초과하게 되면 베이스부재(110)의 절곡이 용이하게 이루어지지 않고, 도전성 패턴층(120)의 탄성력에 의해 스프링백 현상이 나타나 베이스부재(110)가 초기 변형상태를 유지하지 못하게 되는 문제점이 발생하였다. 따라서 도전성 패턴층(120)은 두께가 30 내지 80㎛로 형성되는 것이 바람직하다.As the thickness of the conductive pattern layer 120 becomes thicker, the mold holding force that maintains the bending shape of the base member 110 increases, but when the conductive pattern layer 120 exceeds 80 μm, the bending of the base member 110 is increased. Not easily made, springback phenomenon occurs due to the elastic force of the conductive pattern layer 120 has caused a problem that the base member 110 does not maintain the initial deformation state. Therefore, the conductive pattern layer 120 preferably has a thickness of 30 to 80㎛.

상기 발광램프(130)는 도전성 패턴층(120)에 표면 실장되어 도전성 패턴층(120)을 통해 인가되는 전류에 의해 발광하는 것이다.The light emitting lamp 130 is surface mounted on the conductive pattern layer 120 to emit light by a current applied through the conductive pattern layer 120.

본 실시예의 발광램프(130)는 엘이디가 적용되었으나, 이 외에도 다양한 종류의 발광램프(130)가 적용될 수 있다.Although the LED is applied to the light emitting lamp 130 of the present embodiment, various types of light emitting lamps 130 may be applied.

도 4 및 도 5에는 램프유닛(200)의 제2 실시예가 도시되어 있다.4 and 5 illustrate a second embodiment of the lamp unit 200.

본 실시예의 램프유닛(200)은 베이스부재(210)와, 베이스부재(210)에 형성되는 도전성 패턴층(220)과, 발광램프(230)를 포함한다.The lamp unit 200 according to the present embodiment includes a base member 210, a conductive pattern layer 220 formed on the base member 210, and a light emitting lamp 230.

제1 실시예와 마찬가지로 상기 베이스부재(210)는 장착대상물의 형상에 따라 절곡이 용이하도록 플랙시블한 합성수지재로 형성되며, 발광램프(230) 역시 도전성 패턴층(220)에 장착되어 인가되는 전원을 통해 발광할 수 있도록 되어 있다.As in the first embodiment, the base member 210 is formed of a flexible synthetic resin material to facilitate bending according to the shape of the mounting object, and the light emitting lamp 230 is also mounted on the conductive pattern layer 220 and is applied to a power source. Can emit light through.

본 실시예의 도전성 패턴층(220)은 전류가 통전되어 발광램프(230)에 공급될 수 있도록 형성되며, 베이스부재(210)의 길이방향을 따라 두 줄로 나란하게 연장되어 있다.The conductive pattern layer 220 of the present embodiment is formed so that current can be supplied to the light emitting lamp 230 and extends side by side in two rows along the longitudinal direction of the base member 210.

상기 도전성 패턴층(220)은 베이스부재(210)의 절곡 형성시, 평면상을 따라 연장되는 연장구간(221)과, 절곡되는 절곡부분에 설치되는 확장구간(222)을 포함한다.The conductive pattern layer 220 includes an extension section 221 extending along a plane and an extension section 222 installed at the bent portion when the base member 210 is bent.

상기 연장구간(221)은 통전이 가능하며 베이스부재(210)가 평면상으로 유지될 수 있게 고정력을 제공하도록 동박 성형된 것이다. The extension section 221 may be energized and copper foil-shaped to provide a fixing force so that the base member 210 may be maintained in a plane.

상기 확장구간(222)은 상술한 바와 같이 베이스부재(210)의 절곡부분에 형성되는 것으로, 베이스부재(210)가 절곡되었을 때, 절곡된 형상을 유지시킬 수 있도록 연장구간(221)에 비해 폭이 더 넓게 형성되어 있다.The expansion section 222 is formed in the bent portion of the base member 210 as described above, when the base member 210 is bent, it is wider than the extension section 221 to maintain the bent shape This is wider.

베이스부재(210)를 평면상으로 형태를 고정하는 것보다 절곡된 상태로 고정하는데 따른 고정력이 상대적으로 더 크게 요구되기 때문에 절곡부분에 형성되는 확장구간(222)은 연장구간(221)에 비해 폭이 더 넓게 형성되어 동박층에 의한 충분한 형고정력을 확보하도록 한다.The expansion section 222 formed in the bent portion is wider than the extension section 221 because the fixing force required for fixing the base member 210 in a bent state than the shape fixed in a plane is relatively larger than the extension section 221. It is formed wider to ensure a sufficient mold holding force by the copper foil layer.

또한 확장구간(222)에는 가이드홈(223)들이 형성되어 있다.In addition, guide grooves 223 are formed in the extension section 222.

상기 가이드홈(223)들은 베이스부재(210)의 길이방향과 교차하는 방향을 따라 상호 소정간격 이격되게 연장되어 있으며, 확장구간(222)은 상면으로부터 하방으로 소정깊이 인입되게 형성되어 있다. The guide grooves 223 extend to be spaced apart from each other by a predetermined interval along a direction crossing the length direction of the base member 210, and the expansion section 222 is formed to be inserted in a predetermined depth downward from the upper surface.

베이스부재(210)의 절곡 성형시 가이드홈(223)이 형성된 부분에서의 절곡이 용이하게 이루어지기 때문에 절곡 지점을 통과하도록 가이드홈(223)을 형성해 두면 절곡 지점을 판별하기 위한 별도의 지그를 사용하지 않아도 정확한 위치에서 베이스부재(210)를 절곡시킬 수 있는 이점이 있다.When bending the base member 210, since the bending is easily performed at the portion where the guide groove 223 is formed, when the guide groove 223 is formed to pass through the bending point, a separate jig for determining the bending point is used. There is an advantage that can be bent the base member 210 in the correct position.

상기 가이드홈(223)의 형성 갯수나 모양 등은 도시된 실시예 외에도 다양하게 형성될 수 있다.The number or shape of the guide grooves 223 may be variously formed in addition to the illustrated embodiment.

본 실시예의 도전성 패턴층(220) 역시 동 이외에도 금이나 은 또는 알루미늄과 같이 도전성을 가지는 다른 금속재나 합금이 사용될 수 있다.In addition to copper, other conductive metal layers or alloys having conductivity such as gold, silver, or aluminum may be used.

도 6에는 램프유닛(300)의 제3 실시예가 도시되어 있다.6 shows a third embodiment of the lamp unit 300.

본 실시예의 램프유닛(300) 역시 플랙시블한 베이스부재(310)와, 도전성 패턴층(320) 및 발광램프(330)를 포함하는데, 베이스부재(310)와 발광램프(330)는 제1 실시예와 그 구성 및 기능이 동일하므로 상세한 설명은 생략한다.The lamp unit 300 of this embodiment also includes a flexible base member 310, a conductive pattern layer 320 and a light emitting lamp 330, the base member 310 and the light emitting lamp 330 is a first embodiment Since the example and its structure and function are the same, detailed description is abbreviate | omitted.

본 실시예의 도전성 패턴층(320)은 베이스부재(310)의 길이방향을 따라 두 줄로 나란하게 연장되는데, 베이스부재(310)가 평면상으로 연장되는 부분을 따라 형성되는 제1 구간(321)과, 베이스부재(310)가 절곡되는 절곡부분에 형성되는 제2 구간(322)을 포함한다.The conductive pattern layer 320 of the present embodiment extends side by side in two rows along the longitudinal direction of the base member 310, and the first section 321 is formed along a portion where the base member 310 extends in a plane. The base member 310 includes a second section 322 formed at a bent portion at which the base member 310 is bent.

상기 제2 구간(322)은 절곡된 베이스부재(310)가 절곡된 상태로 고정될 수 있는 고정력을 제공할 수 있도록 제1 구간(321)에 비해 상대적으로 두께가 두껍게 형성되어 있다. The second section 322 has a relatively thicker thickness than the first section 321 to provide a fixing force that can be fixed in the bent base member 310 in a bent state.

이렇게 베이스부재(310)의 평면부분에 비해 상대적으로 더 큰 고정력이 요구되는 절곡부분에 형성되는 제2 구간(322)을 두껍게 하고, 제1 구간(321)은 상대적으로 얇게 형성함으로써 도전성 패턴층(320)의 형성을 위해 사용되는 원자재의 사용량을 최소화할 수 있어 제작비용의 감소 효과를 기대할 수 있다.As such, the second section 322 formed in the bent portion requiring a larger fixing force than the planar portion of the base member 310 is thickened, and the first section 321 is formed relatively thin to form a conductive pattern layer ( It is possible to minimize the amount of raw materials used for the formation of 320) can be expected to reduce the manufacturing cost.

도 7에는 램프유닛(400)의 제4 실시예가 도시되어 있다.7 shows a fourth embodiment of the lamp unit 400.

도면을 참조하면 본 실시예의 램프유닛(400)은 회로부재(410)와, 회로부재(410)를 절곡된 상태로 고정하는 형고정부재(430) 및 발광램프(420)를 포함한다.Referring to the drawings, the lamp unit 400 of the present embodiment includes a circuit member 410, a mold fixing member 430 and a light emitting lamp 420 for fixing the circuit member 410 in a bent state.

상기 회로부재(410)는 베이스플레이트(411)와, 베이스플레이트(411)의 상면에 형성되어 있는 도전패턴(412)을 포함하는데, 베이스플레이트(411)는 필요에 따라 용이하게 절곡할 수 있도록 플렉시블한 합성수지재로 형성된 것이며, 도전패턴(412)은 베이스플레이트(411) 상에 전류가 통전되도록 소정의 패턴을 형성하도록 인쇄되어 있다.The circuit member 410 includes a base plate 411 and a conductive pattern 412 formed on an upper surface of the base plate 411. The base plate 411 is flexible to bend easily as needed. It is formed of one synthetic resin material, and the conductive pattern 412 is printed to form a predetermined pattern on the base plate 411 so that a current flows through it.

상기 발광램프(420)는 상기 도전패턴(412)을 통해 전류가 인가될 수 있게 베이스플레이트(411)에 설치되며, 엘이디램프가 적용되는 것이 바람직하다.The light emitting lamp 420 is installed on the base plate 411 so that a current can be applied through the conductive pattern 412, and an LED lamp is preferably applied.

상기 형고정부재(430)는 회로부재(410)를 필요에 따라 절곡하였을 때, 회로부재(410)가 절곡된 형태를 유지할 수 있도록 형태를 고정하기 위한 것이다.The mold fixing member 430 is for fixing the shape so that the circuit member 410 can maintain the bent shape when the circuit member 410 is bent as needed.

본 실시예의 형고정부재(430)는 회로부재(410)의 상면과 하면에 각각 형성된 제1 코팅층(431)과 제2 코팅층(432)을 포함한다. 형고정부재(430)는 구리가 30 내지 80㎛의 두께로 코팅되어 형성되는데, 제1 실시예의 도전성 패턴층(120)에 대한 설명에서 상술한 바와 같이 형고정부재(430)의 두께가 30㎛ 미만이면 회로부재(410)의 절곡 형상을 유지하기 어려우며, 두께가 80㎛를 초과하게 되면 회로부재(410)의 절곡이 용이하지 않고, 형고정부재(430)의 탄성력에 의해 절곡된 형상을 유지하지 못하고 스프링백 현상이 발생하게 되므로, 형고정부재(430)의 두께는 30 내지 80㎛로 한정되는 것이 바람직하다.The mold fixing member 430 of the present embodiment includes a first coating layer 431 and a second coating layer 432 formed on the top and bottom surfaces of the circuit member 410, respectively. The mold fixing member 430 is formed by coating copper with a thickness of 30 to 80 μm, and the thickness of the mold fixing member 430 is 30 μm as described above in the description of the conductive pattern layer 120 of the first embodiment. If less than, it is difficult to maintain the bending shape of the circuit member 410, If the thickness exceeds 80㎛ bending of the circuit member 410 is not easy, and maintains the shape bent by the elastic force of the mold fixing member 430 Since the springback phenomenon does not occur, the thickness of the mold fixing member 430 is preferably limited to 30 to 80㎛.

제2 코팅층(432)은 회로부재(410)의 하면 전체에 코팅되어 있어서, 제2 코팅층(432)에 의해 회로부재(410)가 외력에 의해 절곡되었을 때, 절곡된 상태를 유지하게 된다.The second coating layer 432 is coated on the entire lower surface of the circuit member 410, so that when the circuit member 410 is bent by an external force by the second coating layer 432, it is maintained in a bent state.

제1 코팅층(431)에는 회로부재(410)가 절곡되는 절곡부분에서의 절곡이 용이하게 이루어질 수 있도록 소정영역 코팅층이 삭제된 삭제부분이 형성되어 있다.In the first coating layer 431, a deletion portion in which a predetermined region coating layer is removed is formed to facilitate bending at the bending portion at which the circuit member 410 is bent.

상기 삭제부분은 회로부재(410)의 길이방향과 직교하는 방향 상에서 절곡이 이루어지는 절곡부분을 따라 코팅층이 삭제된 삭제구간과, 절곡부분의 양측 제1 코팅층(431)을 연결하는 연결구간이 교호적으로 형성되어 있는데, 이렇게 제1 코팅층(431)이 삭제된 삭제구간이 포함되어 있기 때문에 삭제부분에서의 회로부재(410)의 절곡이 상대적으로 용이하게 이루어질 수 있기 때문에 절곡부분을 표시하기 위한 별도의 표시장치나 지그가 없어도 정확한 절곡지점에서의 절곡이 이루어지는 것이 가능하다.The erasing portion alternately includes a deletion section in which a coating layer is removed along a bent portion in which a bending is performed in a direction orthogonal to the longitudinal direction of the circuit member 410, and a connection section connecting both first coating layers 431 on both sides of the bent portion. Since the first coating layer 431 includes a deletion section in which the deletion is performed, the bending of the circuit member 410 in the deletion portion may be relatively easy, so that a separate portion for displaying the bending portion may be provided. It is possible to bend at an accurate bending point even without a display device or a jig.

본 실시예에서는 회로부재(410)의 상면과 하면 모두에 형고정부재(430)인 제1, 제2 코팅층(431,432)이 코팅되어 있으나, 회로부재(410)의 고정상태를 유지하는 충분한 고정력을 제공할 수 있다면, 형고정부재(430)는 회로부재(410)의 상면과 하면 중 선택된 일측면에만 형성될 수도 있다.In this embodiment, the first and second coating layers 431 and 432, which are the mold fixing members 430, are coated on both the upper and lower surfaces of the circuit member 410, but have sufficient fixing force to maintain the fixed state of the circuit member 410. If provided, the mold fixing member 430 may be formed only on one side selected from the upper and lower surfaces of the circuit member 410.
