The present invention is related to assemblies of luminous ornaments having optical fiber cables arranged in parallel, each formed by luminous optical fibers sheathed with a transparent tube, with interlaced connection elements formed therebetween, thereby forming a luminous net when being expanded. The bumper guard is affixed on the curved section of the racket frame, which surrounds the ball racket face having a plurality of holes on the ball-hitting area, and then two sides of the frame converge to form the shaft. The instruction accepting unit accepts an instruction which is an instruction to transmit data via a first communication network or an instruction to transmit data via a second communication network. The querying may identify the number and the feature associated with each of the controller modules to store in a validation module of the master controller module as a database.
