Abstract: A light casing has a semi-circular fixed case, a semi-circular movable case, and two lateral fastening members. Each of the lateral fastening members has a first surface, a second surface, and an orifice disposed near the center of the lateral fastening member. A semi-circular positioning slot is disposed on the periphery of the orifice on the second surface, and a nearly circular sliding slot is disposed on the periphery of the positioning slot on the second surface. The ends of the fixed case are disposed in the positioning slots, and at least one light is disposed on the fixed case. The ends of the movable case are disposed in the sliding slots. When the fixed case overlaps the movable case, the light is uncovered. When the fixed case and the movable case form a covered space, the light is covered.

Abstract: A adjustable light casing comprises: an inner case, the wall surface of which being a half-arc surface, a surface corresponding to the half-arc surface being an opened surface, plural closed rings being disposed two ends of the inner case; an outer case, the wall surface of which being a half-arc surface, a surface corresponding to the half-arc surface being an opened surface, plural closed rings being disposed at the two ends of the outer case; and plural lateral fastening members, each lateral fastening member having an inner ring structure and an outer ring structure.

Abstract: The retractable, light-emitting structure comprises of a string structure that has several light-emitting components: a fixed housing with openings at each end and a mobile housing with openings at each end. The ends of each housing are matched up to create a retractable lid that displays the emitting light inside the fixed housing. The mobile housing would inwardly retract along the fixed housing to make the retractable cover. These structures are ideally installed on the eaves or edges of a housing complex and are controlled by a remote control device that allows for color customization and the ability to control the mobile housing in accordance to different holidays, festivals, and user preference.
