The present invention relates to an LED lamp which is for vehicle lighting and uses MID technology. The LED lamp comprises: a first housing which is composed of a light source accommodating part and a first joint part, wherein the light source accommodating part has a light source seat face that protrudes inward, and the first joint part extends toward a lower side of the light source accommodating part; a second housing which is composed of a second joint part and a socket fastening part, wherein the second joint part has a fastening structure that corresponds to the first joint part so that the first joint part can tilt, and the socket fastening part has a fastening rib that extends toward a lower side of the second joint part; a light source mounting pad which is formed on a surface of the light source seat face and on which a light source is mounted; a socket connection pad which is formed on a surface of the fastening rib and connected to a socket electrode; a light source part seated on the light source mounting pad of the light source seat face; a first trace formed on a surface of the first joint part and connected to the light source mounting pad; and a second trace formed on a surface of the second joint part and connected to the socket connection pad, the second trace being connected to the first trace by fastening the first joint part and the second joint part, wherein the light source mounting pad, the socket connection pad, the first trace, and the second trace are formed on the surfaces of the respective housings by an MID process using a conductive metal, and the first trace and the second trace are kept in contact by the tilting motion of the first joint part and the second joint part. La présente invention concerne une lampe à LED qui est destinée à un éclairage de véhicule et utilise la technologie MID. La lampe à LED comprend : un premier boîtier qui est composé d'une partie de réception de source lumineuse et d'une première partie de jonction, la partie de réception de source lumineuse ayant une face de siège de source lumineuse qui fait saillie vers l'intérieur, et la première partie de jonction s'étendant vers un côté inférieur de la partie de réception de source lumineuse ; un second boîtier qui est composé d'une seconde partie de jonction et d'une partie de fixation de douille, la seconde partie de jonction ayant une structure de fixation qui correspond à la première partie de jonction de telle sorte que la première partie de jonction peut s'incliner, et la partie de fixation de douille a une nervure de fixation qui s'étend vers un côté inférieur de la seconde partie de jonction ; un support de montage de source lumineuse qui est formé sur une surface de la face de siège de source lumineuse et sur laquelle une source de lumière est montée; un support de connexion de douille qui est formé sur une surface de la nervure de fixation et connecté à une électrode de douille ; une partie de source lumineuse placée sur le montage de montage de source lumineuse de la face de siège de source lumineuse ; un première traçage formé sur une surface de la première partie de jonction et connecté au support de montage de source lumineuse ; et un second traçage formé sur une surface de la seconde partie de jonction et connecté au support de connexion de douille, le second traçage étant relié au premier traçage par fixation de la première partie de jonction et de la seconde partie de jonction, le support de montage de source lumineuse, le support de connexion de douille, le premier traçage et le second traçage étant formés sur les surfaces des boîtiers respectifs par un processus MID à l'aide d'un métal conducteur, et le premier traçage et le second traçage sont maintenus en contact par le mouvement d'inclinaison de la première partie de jonction et de la seconde partie de jonction. 본 발명은 MID 기술을 적용한 차량 조명용 LED 램프에 관한 것으로, 내측으로 돌출되는 광원 안착면을 갖는 광원 수용부와, 광원 수용부의 하측으로 연장되는 제1 조인트부로 이루어지는 제1 하우징; 제1 조인트부가 틸팅 가능하도록 제1 조인트부에 대응하는 체결 구조를 갖는 제2 조인트부와, 제2 조인트부의 하측으로 연장되는 체결 리브를 갖는 소켓 체결부로 이루어지는 제2 하우징; 광원 안착면의 표면에 형성되어 광원이 실장되는 광원 실장 패드; 체결 리브의 표면에 형성되어 소켓 전극에 접속되는 소켓 접속 패드; 광원 안착면의 광원 실장 패드에 안착되는 광원부; 광원 실장 패드에 연결되면서 제1 조인트부의 표면에 형성되는 제1 트레이스; 및 소켓 접속 패드에 연결되면서 제2 조인트부의 표면에 형성되어 제1 조인트부와 제2 조인트부의 체결로 제1 트레이스와 접촉되는 제2 트레이스;를 포함하고, 광원 실장 패드, 소켓 접속 패드, 제1 트레이스 및 제2 트레이스는 전도성 금속을 이용한 MID 공정으로 각 하우징의 표면에 형성되며, 제1 트레이스와 제2 트레이스는 제1 조인트부와 제2 조인트부의 틸팅 동작에 대하여 접촉이 유지된다.
