The present invention minimizes a flange diameter of a lower part cover in order to optimize a vibration resistance due to a structural characteristic, and enables a waterproof packing of an upper part back body part and a lower part back body part to be a side surface sealing method O-ring. In addition, the present invention enables a sleeve packing to be inserted into a lamp bracket and a lower part cover, which are a lamp module assembly, to prevent a distributed vibration load to the lower part cover from being transmitted to an LED optical module, and adopts a lamp damage and harness separation prevention structure due to vibration. Therefore, the present invention is capable of realizing a quick maintenance function of the aviation lighting. 본 발명은 구조적 특성상 내진동성을 최적화하기 위해 하부커버의 플렌지 직경을 최소화하고, 상부등체부와 하부등체부의 방수패킹을 측면 실링방식 오링으로 한다. 또한 본 발명은 하부커버로의 분산된 진동 하중이 LED 광학 모듈로 전달되는 것을 방지하기 위하여 램프모듈 조립체인 램프 브라켓과 하부커버에 슬리브 패킹을 삽입하여 진동에 의한 램프 파손 및 하네스 이탈 방지 구조를 채택한다.
