Bracket and connector for modular luminaire and modular luminaire with bracket and connector
A bracket for modular luminaire includes a polyhedral module and a connector connected to the polyhedral module. The polyhedral module is a polyhedron provided with a cavity therein, and each surface of the polyhedron is provided with a stepped through-hole connected to the cavity, thereby forming a first annular protrusion at a junction of the stepped through-hole and the cavity. The connector includes a connector body having a cylindrical shape. On an outer periphery of the connector body, a second annular protrusion, a third annular protrusion, a fourth annular protrusion, and a fifth annular protrusion protrude outwards in a radial direction and are spaced apart from each other, and formed successively from a left end portion to a right end portion of the connector body. A left end of the connector is inserted into the stepped through-hole of the polyhedral module.
