Abstract

본 발명은 자동차 내부의 스위치 위치 및 각종 시그널을 조명하는 인테리어 조명장치에 관한 것으로, 운행되는 자동차이 주변환경 밝기를 검출하여 인테리어 램프이 밝기가 자동으로 조절되도록 한 것이다. 본 발명은 운행되는 자동차의 각종 스위치 위치 및 시그널의 상태를 운전자에게 지시하는 인테리어 램프이 밝기가 광 검출수단에서 검출되는 주변환경의 밝기에 따라 자동으로 조절되므로 운행의 안전성 및 편리성이 제공되고, 밝기 조절부의 선택에 따라 인테리어 램프이 밝기를 운전자의 성향에 적합하게 조절할 수 있어 사용자의 욕구를 충족시킨다.The present invention relates to an interior lighting apparatus for illuminating a switch position and various signals in an automobile. The driving vehicle detects the brightness of the surrounding environment so that the interior lamp is automatically adjusted. The present invention provides a safety and convenience of driving because the interior lamp for instructing the driver of the various switch positions and the state of the signal of the driving vehicle is automatically adjusted according to the brightness of the surrounding environment detected by the light detection means, brightness Depending on the selection of the control unit, the interior lamp can adjust the brightness to suit the driver's preferences to meet user needs.
