Abstract: A lighting assembly and a lighting device are provided. The lighting assembly is U-shaped and includes a radiator, a light-emitting plate and a connector. The radiator is provided with a rotating groove and an avoidance notch communicated with the rotating groove. The rotating groove is provided on the inner side of the radiator, and the avoidance notch extends from the rotating groove to the edge of the radiator. The light-emitting plate is provided on the radiator and includes a plurality of light-emitting diode (LED) lamps in parallel and/or in series. The connector includes a first connecting part and a second connecting part. The first connecting part is configured to be connected to a free end of a telescopic assembly, and the second connecting part is placed in the rotating groove. The avoidance notch provides a space for the movement of the first connecting part.

Abstract: A base assembly includes a mounting structure and a support structure. The mounting structure includes a base body, a main body, and a guide rod provided between the base body and the main body. The support structure includes a sliding element and support legs. The sliding element is slidably connected to the guide rod. Each of the support legs is provided with a rotating end and a support end that are arranged opposite to each other. The rotating end is rotatably connected to the sliding element. The sliding element is slidable toward the main body to drive a plurality of support ends to approach each other, such that the base assembly is in a folded state. One of the base body and the support leg is provided with a first locking element, and the other of the base body and the support leg is provided with a second locking element.

Abstract: A lighting device includes a base assembly provided therein with a circuit board; a telescopic assembly provided with a fixed end and a free end that are arranged oppositely, where the fixed end is connected to the base assembly; and a lighting assembly rotatably connected to the free end to rotate axially and radially along the free end, where the lighting assembly is provided with a lighting element electrically connected to the circuit board. The lighting device realizes the extension and retraction of the lighting assembly and the lighting element through the telescopic assembly, such that the height adjustment of the lighting device can be realized in a large range, which is convenient for storage and carrying. In addition, in the lighting device, the lighting assembly and the free end are movably connected, such that the lighting assembly is rotatable axially and radially along the free end.
