Zusammenfassung:The present invention relates to a ceiling lighting system for a tollgate, which illuminates a tollgate, and more particularly, to a ceiling lighting system for a tollgate, which has two lighting groups installed in a lane of a tollgate, allows the two lighting groups to be supplied with power from separate ballasts, respectively, to reduce the number of installed ballasts, and allows a normally operating lighting group to illuminate the lane of the tollgate even when a problem occurs in one lighting group or ballast to prevent inconvenience in using the tollgate. The ceiling lighting system for a tollgate according to the present invention comprises: a first lighting group and a second lighting group for illuminating a lane of a tollgate; and a first ballast and a second ballast for supplying power to the first and second lighting groups, respectively. 본 발명은 톨게이트을 조명하는 톨게이트 천정등에 관한 것으로서, 보다 상세하게는 톨게이트의 차선에 두 개의 조명군을 설치하고, 두 조명군은 각각 별개의 안정기에서 전원을 공급받아서, 안정기의 설치수량을 줄이고, 어느 한 조명군이나 안정기에 문제가 발생되더라도 톨게이트 차선은 정상 작동하는 조명군에 의해 조명되도록 하여 톨게이트 사용의 불편을 방지하는 톨게이트 천정등에 관한 것이다. 본 발명에 따른 톨게이트 천정등은 톨게이트의 차선을 조명하는 제1조명군과 제2조명군;상기 제1조명군과 제2조명군에 각각에 전원을 공급하는 제1안정기와 제2안정기;를 포함하여 이루어진다.
