Abstract: An ultra-thin narrow-bezel panel light includes a base plate and a bezel surrounding the base plate. The base plate includes a plurality of side walls and an accommodating portion between the side walls, and the height of the base plate is 18 mm˜26 mm. Each of the side walls has a connecting side and the side walls are installed and fixed on the bezel via the connecting sides thereof, such that the overall height of the panel light can be reduced to 20 mm˜28 mm. Thus, the panel light can be ultra-thin, low-cost and of narrow bezel.

Abstract: A linear lamp having splicing member includes a lamp body, an extension module and a splicing member. The splicing member has two fixing portions disposed at the two ends thereof respectively. The two fixing portions of the extension module are engaged with the first combining member of the lamp body and the second combining member respectively in order to splice the extension module and the lamp body with each other. Via the above structure, the functional extension of the linear lamp can be realized by linear splicing mechanism, such that various extension functions can be conveniently and efficiently added to the linear lamp regardless of the environment.

Abstract: A track lighting is provided, which mainly includes a track structure and a light source installation base. The track structure includes an installation base, a first lateral wall and a second lateral wall circuitously extending from the two sides of the installation base respectively. The first locking portion at one end of the first lateral wall is engaged with the first buckle portion of the light source installation base, and the second locking portion at one end of the second lateral wall is engaged with the second buckle portion of the light source installation base. Besides, after the stopper structure of the light source installation base is inserted into the stopper space between the stopper element and the corresponding stopper portion of the second lateral wall, the stopper element and the corresponding stopper portion are at the two sides of the stopper structure.

Abstract: A frame structure for ceiling lighting device is provided, which includes a plurality of first frame bars, a plurality of second frame bars and a plurality of corner braces. Each first frame bar includes a first frame bar body and a first chamber structure disposed on one side of the first frame bar body. Each second frame bar includes a second frame bar body and a second chamber structure disposed on one side of the second frame bar body. Each corner brace includes a first extension arm inserted into an opening at one end of the first chamber structure of one of the first frame bars and a second extension arm inserted into the opening at one end of the second chamber structure of one of the second frame bars, such that the first frame bars and the second frame bars can be combined with each other.

Abstract: A track light with phase-switching device includes a track assembly, a light source base, and a power module. The track assembly includes an installation base, a first side wall, and a second side wall. The first side wall and the second side wall are respectively disposed at opposite sides of the installation base. One end of the first side wall has a first fixation portion, and one end of the second side wall has a second fixation portion. The light source base is assembled with the track assembly. The light source base includes a heat dissipation base and a light source plate. The light source plate is located on the heat dissipation base. The power module includes wirings and a phase-switching device. The power module is electrically connected to the light source plate through the wirings. The phase-switching device is provided for switching a phase of the wirings.

Abstract: A rotary lamp cap, includes a casing element, a rotary loop, and a side end cover. The casing element and the side end cover are respectively sleeved on a groove at each side of the rotary loop. When the rotary loop moves away from the casing element, the rotary loop and the casing element change from the original buckled state to the disengaged state. An outside end face of the side end cover includes a flat area and two plug-in holes, the flat area is located outside the plug-in holes, and two conductive poles are respectively plugged in the plug-in holes. No other holes except for the plug-in holes are provided on the end face of the side end cover, thereby enabling the side end cover to have locking function with no air hole.
