The present invention relates to an input voltage stabilization circuit of a rear combination lamp, which includes: a light output unit including a plurality of organic light emitting diode (OLED) elements; a DC-DC converter unit for providing an output voltage suitable for driving the plurality of OLED elements by stepping up or down the voltage of a main power source supplied from a battery for a vehicle; and a feedback unit for providing information of the highest required voltage value among required voltage values of each of the plurality of OLED elements to the DC-DC converter unit as feedback, wherein the DC- DC converter unit controls the output voltage based on the feedback. Accordingly, the present invention can effectively transmit a signal without inducing the glare of a driver of the other vehicle.

    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.
