The annular grooves comprise a plurality of arc grooves which are not in communication with each other.

The present invention provides a technical solution of a method for mounting the flat lamp with a light guide plate, characterized in that the method comprises steps as follows.

1. Screwing a screw into an arc groove of the cover plate of the fixing assembly and into a screw hole provided at an end of the support plate member, and fixing the fixing assembly on a roof;

2. Moving the support plate member to allow it to slide into the V groove of the support plate assembly and then continue sliding until being restrained by the bent plate at an end.

Advantages

1. The lamp is easy to mount.

2. The lamp has a thin structure, large luminous area and narrow frame. It may merge into the roof without ruining the style of the roof and can be widely used.

3. The lamp has elegant appearance and no light leakage occurs at four corners when the lamp is turned on.
