Apparatus for coupling a luminaire with a surface includes a mounting plate having or more studs extending therefrom, a back plate for a luminaire, and a latch. The back plate forms slots that can receive the studs. The back plate can move in a first direction with the studs received within the slots. The latch couples with the back plate, and can engage one of the studs that extends through one of the slots. In a first rotational position of the latch with respect to the back plate, the latch does not engage the stud, and in a second rotational position of the latch with respect to the back plate, the latch engages the stud in a direction different from the first direction, so as to constrain movement of the back plate in the first direction, latching the back plate to the mounting plate.

A luminous advertisement assembly includes a side wall, a transparent and/or translucent front plate and a profiled connecting element. The profiled connecting element has a first connecting region to which the front plate is fixed, and a second connecting region to which the side wall is fixed. The first connecting region is configured as a receptacle having a first leg and a second leg between which the front plate is received. A latching hook is disposed on the first leg and is configured to fix the front plate in the receptacle. A recess is disposed in the front plate, and the latching hook of the profiled connecting element engages in the recess of the front plate.

A split-type ceiling lamp comprising a lamp body, a diffusion cover and a base, wherein the lamp body is provided with an electric apparatus groove and a mounting groove. A light source is mounted in the electric apparatus groove, and the diffusion cover is clamped with the lamp body. The base is embedded in the mounting groove and is provided with a wiring terminal, which is connected to the light source through a power coupling module. The power coupling module comprises a socket portion and a connector portion. The socket portion is connected to the light source, the connector portion is connected to the wiring terminal, and the base is clamped with the lamp body. According to the present disclosure, the base with light weight and small volume is fixed on the ceiling first, and then the lamp body is clamped with the base, which achieves convenient assembly and disassembly.
