Abstract

본 발명의 플랫 라이트 장치는 휴대시에 진동을 받게 되는 경우에 그 내부의 발광체에 대한 도입선들이 우발적으로 파손되는 것을 방지하도록 고안되어 있으며, 결과적으로 상기 플랫 라이트 장치의 전체 신뢰도를 향상시키는 장치이다. 상기 플랫 라이트 장치는 패널 형상의 투명 기판과, 상기 기판의 단면에 고정되어 있는 광원 장착부와, 상기 광원 장착부에 고정되어 있는 튜브형 발광체로 구성되며, 상기 광원 장착부는 도전성 물질로 이루어져 있고, 그의 개방 측면에서 상기 단면과 결합되도록 대체로 U자형인 단면을 가지고 있으며, 또한 상기 발광체의 한쪽 도입선은 상기 광원 장착부에 접속되어 있어 발광체를 위한 파워 공급부를 그 위에 형성한다.
