Description

자동차용 엘이디램프{LED LAMP FOR AUTOMOBILE}LED lamp for automobile {LED LAMP FOR AUTOMOBILE}

본 발명은 자동차용 엘이디램프에 관한 것으로서, 상세하게는 방열기능을 간단히 부여해줄 수 있도록 하면서 방열이 보다 효과적으로 이루어질 수 있도록 한 것이다.The present invention relates to an LED lamp for a vehicle, and in detail, it is intended to allow the heat dissipation to be made more effectively while providing a simple heat dissipation function.

일반적으로 자동차의 실내에는 야간에 탑승자에게 도움을 주기위하여 맵 램프(Map lamp)와 룸 램프(Room lamp) 및 카고 램프(Cargo lamp) 등과 같은 실내등이 설치되고 또 실외에는 안전한 주행을 위하여 방향지시등과 브레이크등 및 미등 등과 같은 실외등이 설치되는데, 근래에 들어서는 이러한 자동차의 실내등과 실외등에도 소비전력이 낮고 반영구적인 엘이디램프가 널리 이용되고 있다.In general, indoor lights such as map lamps, room lamps, and cargo lamps are installed in the interior of a car to help passengers at night, and turn indicators and turn signals are installed outdoors for safe driving. Outdoor lights such as brake lights and tail lights are installed. Recently, LED lamps with low power consumption and semi-permanent power are widely used in indoor and outdoor lights of automobiles.

따라서 자동차의 실내등과 실외등으로 이용되는 엘이디램프에 대하여 이미 등록특허 10-1519983호 '자동차 실내등용 엘이디램프' 및 공개특허 10-2017-0102611호 '자동차 실내등용 엘이디램프 및 그 제조방법' 등을 제공한바 있으며, 이들 중 자동차 실내등용 엘이디램프의 경우 좌우로 긴 인쇄회로기판의 중앙부에 엘이디와 회로부품을 실장하여 양측단부에 형성된 접속부를 이용하여 소켓의 좌우탄성단자 사이에 결합해주도록 구성되고 또 자동차 실외등용 엘이디램프의 경우 인쇄회로기판의 수직부 전면에 엘이디를 실장함과 아울러 수평부의 엘이디 인근에 회로부품을 실장하여 수평부 단부에 걸림턱을 갖도록 형성된 접속부를 이용하여 걸림홈을 갖는 소켓에 결합해 주도록 구성되며, 특히 엘이디램프는 엘이디의 발광시 고열이 발생하여 관련부품의 수명을 단축시키게 되므로 인쇄회로기판의 단부에 별도로 제작된 방열체를 결합하여 엘이디의 발광시 방열이 이루어지도록 구성된다.Therefore, for LED lamps used as indoor and outdoor lights of automobiles, registered Patent No. 10-1519983'LED lamps for automobile interior lights' and'Patent Publication No. 10-2017-0102611''LED lamps for automobile interior lights and its manufacturing method' In the case of LED lamps for interior lighting of automobiles, among them, the LED and circuit parts are mounted in the center of the printed circuit board that is long left and right, and it is configured to be coupled between the left and right elastic terminals of the socket using the connection formed at both ends. In the case of an LED lamp for an automobile outdoor light, the LED is mounted on the front of the vertical part of the printed circuit board, and circuit parts are mounted near the LED in the horizontal part, and the connection part formed to have a locking protrusion at the end of the horizontal part is used in a socket having a locking groove. In particular, the LED lamp generates high heat when the LED emits light, which shortens the life of related parts, so by combining a separately manufactured radiator at the end of the printed circuit board, it is configured to radiate heat when the LED emits light. .

그러나 자동차용 엘이디램프에 방열기능을 부여해주기 위하여 별도로 제작된 방열체를 별도의 조립공정을 통하여 인쇄회로기판에 결합고정해주도록 할 경우 현저한 생산성저하를 가져오게 되고 또 이로 인한 제조원가상승으로 제품의 가격경쟁력이 떨어지게 되며, 사용시에는 인쇄회로기판과 방열체 사이에 갖는 틈으로 인하여 방열이 제대로 이루어질 수 없게 되는 등 많은 문제점들이 있는 것이다.However, if the separately manufactured radiator is coupled and fixed to the printed circuit board through a separate assembly process in order to provide the heat dissipation function to the automotive LED lamp, the product price is significantly lowered and the manufacturing cost is increased. Competitiveness is lowered, and when used, there are many problems such as that heat dissipation cannot be properly performed due to a gap between the printed circuit board and the radiator.
