Since the reinforcing tube 3 is wrapped around the periphery of the mounting members 41, the mounting members are provided. The protection and supporting force can prevent the luminaire from being twisted and deformed during the transportation process, and the control board 631 of the illuminating control module 63 is pressed against the hard reinforcing tubes 3 through the mounting member 41. Since the reinforcing tube 3 has a fixed shape, the control board 631 is protected from being deformed or displaced by an external force, and similarly, the conductive strips 633 are not deformed or bent by an external force, so that the conductive strip can be avoided. The welded portion of the 633 and the control board 631 is shaken off and is detached, so that the present invention can improve the mounting stability of the component.

It is worth mentioning that the present invention uses two reinforcing tubes 3 spaced apart from each other, instead of forming the reinforcing tube 3 into a tube having a length equal to that of the outer tube 2, mainly because of two short length reinforcing tubes. 3 is lighter in weight and uses less material to avoid unnecessary cost. Therefore, the present invention achieves the purpose of stabilizing component assembly at a low cost, which is a quite practical and innovative design.
