The present invention relates to a vehicle LED lamp applying a MID technology which is capable of radiating heat generated inside an accommodation portion of a housing, the vehicle LED lamp comprising: a housing (10) which is injection-molded; an LED module (20) disposed in an accommodation portion (11) of the housing (10); a surface electrode (30) formed on a surface of the housing (10); and a diffusion cover (40) coupled to the accommodation portion (11) of the housing (10) so as to cover the LED module (20). The housing (10) comprises the accommodation portion (11) having a cup shape so as to accommodate the LED module (20); and a socket coupling portion (12) which is integrally formed on a lower portion of the accommodation portion (11), wherein a heat sink (13) in which a plurality of heat radiation grooves (131) and a plurality of heat radiation ribs (132) are alternately disposed around the accommodation portion (11) is formed. 본 발명은 하우징의 수용부 내부에서 발생하는 열을 잘 방열할 수 있는 MID 기술을 적용한 자동차 LED 램프에 관한 것으로서, 사출성형된 하우징(10)과, 하우징(10)의 수용부(11)에 배치되는 LED 모듈(20)과, 하우징(10)의 표면에 형성되는 표면 전극(30)과, 하우징(10)의 수용부(11)에 결합되어 LED 모듈(20)을 커버하는 확산 커버(40)를 포함하는 MID 기술을 적용한 자동차 LED 램프에 있어서, 상기 하우징(10)은 LED 모듈(20)을 수용할 수 있도록 컵 형상으로 형성된 수용부(11)와, 수용부(11)의 하부에 일체로 형성되는 소켓 체결부(12)로 구성되고, 수용부(11)의 둘레에 복수개의 방열홈(131)과 복수개의 방열 리브(132)가 교대로 배치되는 히트싱크(13)가 형성되는 것을 특징으로 한다.
