Abstract: A ceiling lamp with a night lamp includes a chassis, a diffusion cover, a main light source, a light shield, and a night lamp light source. The diffusion cover is disposed on the chassis, and the chassis and the diffusion cover are enclosed to form an accommodating cavity; and the main light source is disposed in the accommodating cavity, the light shield is disposed in the accommodating cavity and is disposed around the main light source, and the night lamp light source is disposed on an outer wall surface of the diffusion cover. The main light source of the ceiling lamp with the night lamp is used for emitting strong light, and the night lamp light source is used for emitting weak light. The light shield is used for limiting an irradiation direction of the night lamp light source.

Abstract: A dual-purpose mounting mode ceiling lamp mounting device includes a main body bracket and two groups of connecting assemblies. The main body bracket is strip-shaped; the main body bracket is provided with a J-BOX connection hole; ends of the connecting assemblies are detachably connected with the main body bracket, and two groups of the connecting assemblies are respectively slidably provided at two ends of the main body bracket, the sliding direction is a length direction of the main body bracket; the other ends of the connecting assemblies are configured to connect with an external structure. The main body bracket is provided with detachable connecting assemblies and a J-BOX connection hole, when it is necessary to mount the ceiling lamp in the J-BOX mode, the connecting assembly can be disassembled from the main body bracket to mount the ceiling lamp in the J-BOX mode.

Abstract: Disclosed are an elastic assembly and a down lamp. The down lamp includes a lamp body and an elastic assembly. The elastic assembly includes a limiting assembly and a spring. The limiting assembly is provided with a rotating cavity. The fixing end of the spring is rotatably embedded in the rotating cavity, so that a flip angle of a movable end of the spring ranges from 0° to 90°. The present disclosure can enlarge the adjustable angle of the spring and reduce the assembly difficulty of the down lamp.

Abstract: Disclosed is a night downlight, including a plastic housing, a light source plate, a reflective cup, and a light guide sleeve. The plastic housing is provided with an opening, and the light source plate is arranged on an inner side of the plastic housing opposite to the opening. The light source plate is provided with a first light source and a second light source. One end of the reflective cup abuts against the light source plate. The light guide sleeve is arranged between the other end of the reflective cup and the plastic housing. The light guide sleeve is in snap-fit with the reflective cup. The snap-fit design of the light guide sleeve and the reflective cup allows replacement of the small component rather than replacement of the whole face ring when the snap-fit structure fails, thereby effectively reducing waste in repair and replacement.
