When the luminaire needs to be mounted on a base such as a roof or a ceiling, the operator only needs to push up the connecting base 2, so that the second receiving cavity 2B of the second main body portion 2A of the connecting base 2 receives the first main body of the fixing base 1. The portion 1A, and then only by axially rotating the connecting seat 2, can simultaneously realize the mechanical connection between the first joint portion of the fixed seat 1 and the second joint portion of the joint seat 2 and the first electrical connection portion and connection of the fixed seat 1 The electrical connection between the second electrical connections of the seat 2, in turn, achieves a mechanical and electrical connection of the luminaire. Here, the term "axial direction" used in the preferred embodiment of the present invention means the axial direction of the fixing base 1. The term "push up" as used in the preferred embodiment of the invention means that the connecting seat 2 is pushed in the axial direction toward the mounting seat 1 or the connecting seat 2 is oriented in the axial direction toward the connecting seat 2 and the fixed seat. The relative distance between 1 is pushed in a direction that decreases.

When the luminaire is disassembled, the operator only needs to push up the connecting base 2 and then rotate the connecting base 2 in the opposite direction, and then separate the connecting base 2 from the fixed seat 1 to release the first joint portion of the fixed seat 1 and the connecting seat 2 The electrical connection between the second joints and the electrical connection between the first electrical connection of the mount 1 and the second electrical connection of the mount 2 further removes the luminaire.

When the two joint portions are connected, an axial force is applied to the bottom end surface of the first body portion of the fixing seat. Further, the elastic member 10 may be simultaneously disposed on the bottom end surface of the first body portion of the mount and on the bottom end surface of the second housing chamber of the connector (not shown). Further, the elastic member 10 is a spring or other metal shrapnel knot. Preferably, as shown in FIG. 2, the elastic member 10 disposed on the bottom end surface of the first body portion of the fixing base includes an elastic portion 101 and a pressing portion 102, and the pressing portion 102 is fixedly connected with the elastic portion 101. When the fixing base 1 and the connecting base 2 are connected, the elastic portion 101 is pressed by the protective cover, so that the pressing portion 102 of the elastic member 10 is pressed downward to press the bottom end surface of the connecting seat 2, and the elastic portion 101 is subjected to the elastic portion 101 at this time. In the pressed state, an axial force is generated between the fixed seat 1 and the connecting seat 2 to ensure that the connecting seat does not move up, down, left, and right relative to the fixed seat after the installation of the lamp is completed. Further, the elastic member 10 is uniformly disposed at a position close to the first joint portion at the center of the bottom end surface of the first body portion 1A or at the bottom end surface of the second receiving chamber 2B of the joint seat 2 The center is uniformly disposed at a position close to the second joint.

The U-shaped mounting groove 5 includes an open end 51 and a limiting structure 52. When the fixing base 1 is coupled with the connecting base 2, the projection 3 of the fixing base 1 is loaded from the open end 51 of the U-shaped mounting groove 5, and rotates along the circumferential direction of the inner wall of the second receiving cavity 2B until it is rotated to the U-shaped mounting. The stop structure 52 of the groove 5 is mounted in place, that is, the first joint of the fixed seat 1 and the second joint of the joint 2 are mechanically connected.

Preferably, as shown in FIG. 1 , the limiting structure 52 of the U-shaped mounting groove 5 and the open end 51 have a height difference, and the limiting structure 52 is higher than the open end 51 . When the lamp is mounted, the connecting seat 2 is pushed up, and the axial force of the elastic member 10 against the connecting seat 2 is overcome, and the bump 3 of the connecting seat 2 is pushed to the vicinity of the open end 51 of the U-shaped mounting groove 5, and then the bump is pushed. 3 enters from the open end 51 of the U-shaped mounting groove 5 and rotates along the circumferential direction of the second receiving cavity inner wall 2B to abut against the inner side wall of the limiting structure 52. Due to the axial force of the elastic element 10, the connecting seat 2 will be moved axially away from the fixing seat 1 until the top surface of the projection 3 of the fixing seat 1 and the limiting structure 52 of the connecting seat 2 Top surface The mechanical connection between the first joint of the fixed seat 1 and the second joint of the joint 2 is achieved by the fitting. After that, between the fixing seat 1 and the connecting seat 2, the axial force generated by the elastic member 10 is always present, and the fixing seat 1 and the connecting seat 2 are more firmly engaged with each other under the action of the gravity of the lamp itself. There will be no swaying of the lamps up and down and left and right.

Preferably, the number of the second joints is a multiple relationship with the number of the first joints, and the number of the second joints is not less than the number of the first joints.

Specifically, when it is necessary to separate the fixing base 1 and the connecting base 2, the operator cannot separate the fixing base 1 and the connecting base 2 directly by rotating the connecting base 2 in reverse, because the hook is present due to the presence of the hooking portion 54 The hinge portion 54 blocks the projection 3 from being directly removed from the U-shaped mounting groove 5. At this time, the operator needs to push up the connecting seat 2 first. Since the positions of the fixing seat 1 and the protruding block 3 are fixed, the upward movement of the connecting seat 2 will result in the top surface of the bump 3 and the U-shaped mounting groove which are originally attached to each other. The inner top surfaces of the limiting structures 52 of 5 are separated from each other, The open end 51 of the U-shaped mounting groove 5 is also moved to a position equal to the height of the bump 3, and then the connecting seat 2 is reversely rotated, so that the detachment of the luminaire can be achieved.
