The present invention relates to an LED lighting module (1) for a vehicle, which comprises: an LED lamp (10) including a large number of light-emitting diodes (100); a first driver module (11) configured to drive the LED lamp (10) at a first DC voltage level (U_hi); a second driver module (12) configured to drive the LED lamp (10) at a second DC voltage level (U_lo) which is lower than the first DC voltage level (U_hi); and switch arrangements (13, 130) including interfaces (151, 152) for accessing a two-level DC voltage source (PS). The switch arrangements (13, 130) are configured to access the first driver module (11) to the LED lamp (10) when an input voltage is at a first level (U_hi), and access the second driver module (12) to the LED lamp (10) when the input voltage is at a second level (U_lo). The present invention additionally describes a vehicle lighting system (2) of a vehicle (3) and a method for operating the vehicle LED lighting system (2). The present invention aims to provide an LED lighting module for a vehicle, which is able to save space and reduce costs.

    본 발명은 다수의 발광 다이오드(100)를 포함하는 LED 램프(10); LED 램프(10)를 제1 DC 전압 레벨(U_hi)에서 구동시키도록 구성된 제1 구동기 모듈(11); LED 램프(10)를 제1 DC 전압 레벨(U_hi)보다 낮은 제2 DC 전압 레벨(U_lo)에서 구동시키도록 구성된 제2 구동기 모듈(12); 2-레벨 DC 전압원(PS)에의 접속을 위한 인터페이스(151, 152)를 포함하는 스위치 배열(13, 130) -스위치 배열(13, 130)은 입력 전압이 제1 레벨(U_hi)에 있을 때 제1 구동기 모듈(11)을 LED 램프(10)에 접속하고, 입력 전압 레벨이 제2 레벨(U_lo)에 있을 때 제2 구동기 모듈(12)을 LED 램프(10)에 접속하도록 구성됨- 을 포함하는 자동차 LED 조명 모듈(1)을 설명한다. 본 발명은 차량(3)의 자동차 조명 시스템(2), 및 자동차 LED 조명 시스템(2)을 동작시키는 방법을 추가로 설명한다.
