Abstract: A frame for a ceiling light fixture comprises a main body formed into a rectangular board, first and second side-panels formed by folding up both sides of the main body along the longitudinal direction thereof, and first and second hooking members formed on both sides of main body between the side-panels. The main body has a circular cavity for coupling the ceiling light fixture therein. Each side-panel has hooking apertures formed on both sides thereof and a plurality of hooks protruded outward between the hooking apertures. Each hooking member is bended to the same direction as the side-panel and has a hooking aperture therein. The hooking apertures of the side-panels and the hooking member are positioned on the same line. The supporting member for fixing the ceiling frame is hooked at three points, that is, at the both sides and center of the frame, thereby preventing the frame from wrapping.

Abstract: A hanger bar for mounting a ceiling light fixture is formed of shortening the length thereof, thereby mounting regardless of the width of the ceiling frame and comprises first and second bars having cutting lines formed at regular intervals. The first bar has folding hooks formed along the longitudinal direction on both sides of the crosswise direction thereof. The second bar has a convex part protruded to one side along the longitudinal direction. The second bar is mounted to slide in the folding hooks of the first bar. Coupling parts for attaching the bars are formed in each end of the bars as one body. The coupling parts are folded perpendicular to the surface of the bars and has coupling members formed by punching. The coupling member has a chock, so that the hanger bar can be coupled with the ceiling frame by using a simple stroke.
