본 발명은, 복수의 OLED(Organic Light Emitting Diode) 소자를 포함하는 광출력부; 차량용 배터리에서 공급되는 메원 전원의 전압을 승압 또는 강압하여, 상기 복수의 OLED의 구동에 적합한 출력 전압을 제공하는 DC-DC 컨버터부; 및 상기 복수의 OLED 소자 각각의 필요 전압값 중, 가장 높은 필요 전압값의 정보를 상기 DC-DC 컨버터부에 피드백으로 제공하는 피드백부;를 포함하고, 상기 DC-DC 컨버터부는, 상기 피드백을 기초로, 상기 출력 전압을 조정하는 리어 콤비네이션 램프의 입력 전압 안정화 회로 에 관한 것이다.
An input voltage stabilization circuit for a rear combination lamp is disclosed. The input voltage stabilization circuit includes an optical output unit including a plurality of Organic Light Emitting Diodes (OELDs), a Direct Current to Direct Current (DC-DC) converter configured to supply an output voltage for driving the plurality of OLEDs by raising or lowering a voltage of a main power supplied by a vehicle battery, and a feedback unit configured to provide information about a highest of voltage values required for the plurality of individual OLEDs, as a feedback to the DC-DC converter. The DC-DC converter adjusts the output voltage based on the feedback.
