The present invention relates to an LED lamp for replacing an automotive filament lamp. The LED lamp for replacing an automotive filament lamp includes: an LED module lighting on an LED by a driving signal, and replacing a filament lamp to be mounted inside a vehicle; and a load module outputting a body control module (BCM) check signal to the LED module by lowering the voltage level of the BCM check signal when a vehicle′s interior lamp check signal (BCM check signal) outputted from a BCM is inputted. The LED module can be turned on by an LED driving signal but cannot be turned on by the BCM check signal of which the voltage level has been lowered by the load module. According to the present invention, since a BCM check signal having a voltage level lowered through a load and a switching circuit is inputted into an LED, the LED cannot be turned on by the BCM check signal and a warning indication does not appear, which can lead to an increase in user convenience. Moreover, when an automotive filament lamp is replaced with an LED lamp in an aftermarket purchase, the LED lamp by the present invention does not require the purchase of a separate error canceller and has size compatibility with existing filament lamps, thus conveniently replacing a filament lamp with an LED lamp.

    본 발명은 자동차 필라멘트 램프 대체용 LED 램프에 관한 것으로서, 자동차 필라멘트 램프 대체용 LED 램프는 구동 신호에 의해 LED가 점등되며, 필라멘트 램프를 대체하여 자동차 실내에 장착되는 LED모듈; 및 BCM(Body Control Module, 차체제어모듈)에서 출력되는 자동차 실내등 체크 신호(BCM 체크신호)가 입력되면 BCM 체크신호의 전압레벨을 낮춰 LED 모듈로 출력하는 부하모듈을 포함하며, 그 LED 모듈은 LED 구동신호에 의해서는 점등되지만 부하모듈에 의해 전압레벨이 낮추어진 BCM 체크신호에 의해서는 점등되지 않는다. 본 발명에 의하면, 스위칭 회로와 부하를 통해 BCM체크신호의 전압레벨을 낮추어 LED로 입력되게 함으로써, BCM체크신호에 의해 점등되지 않아 경고 표시가 발생되지 않아 사용자 편의성을 높일 수 있다. 또한, 그리고 본 발명에 의한 LED 램프는 애프터 마켓에서 자동차의 필라멘트 램프를 LED램프로 대체할 때 별도의 에러 캔슬러(Error Canceller)를 구매할 필요 없고 기존의 필라멘트 램프와 사이즈 면에서 호환성이 있으므로, 편리하게 필라멘트 램프를 LED 램프로 대체할 수 있다.
