The implementation principle of the lamp capable of rotating with multiple degrees of freedom in the embodiment of the application is as follows: bearing inner ring 2 rotates with installation outer ring 1 to be connected, and the solid fixed ring of light source 3 rotates with bearing inner ring 2 to be connected, and light source module 4 passes through limit structure and installs in solid fixed ring of light source 3. After the installation outer ring 1 is fixedly installed at a preset installation position, a user can rotationally adjust the bearing inner ring 2; meanwhile, the user can adjust the angle of the light source fixing ring 3, and under the condition that the light source fixing ring and the light source fixing ring are matched, the adjusting range of the irradiation area of the lighting lamp is expanded in a limited mode.

Specifically, the bearing inner ring 2 and the mounting outer ring 1 are embedded into the transverse angle clamping groove 25 through the embedding part 521 of the movable elastic sheet 52, so that the bearing inner ring 2 and the mounting outer ring 1 are kept relatively fixed; in the process of rotatably supporting the inner ring 2, the movable spring plate 52 is elastically deformed in the direction close to the connecting sheet 51 under the abutting action of the side wall of the transverse angle clamping groove 25. When the embedded part 521 of the movable elastic sheet 52 corresponds to the adjacent transverse angle slot 25, the movable elastic sheet 52 allows the embedded part 521 to be clamped into the transverse angle slot 25 due to the elastic restoring force of the movable elastic sheet, so as to achieve the self-locking effect of limiting the random rotation of the bearing inner ring 2.

The light source fixing ring 3 and the bearing inner ring 2 are clamped into the positioning groove 713 in the circular containing groove 712 by the clamping part 732 of the elastic adjusting piece 73, so that the rotation between the light source fixing ring 3 and the bearing inner ring 2 is limited. In the process that the user rotates the light source fixing ring 3, the clamping portion 732 of the elastic adjusting member 73 moves along the arrangement direction of the positioning grooves 713, and under the force of the protrusion between two adjacent positioning grooves 713, the clamping portion 732 of the elastic adjusting member 73 moves towards the direction of retracting into the movable groove 7211, so that the resilience portion 731 of the elastic adjusting member 73 is elastically deformed in the movement. When the latch portion 732 of the elastic adjustment member 73 moves to a position corresponding to the other positioning groove 713, the latch portion 732 is latched into the positioning groove 713 by the elastic restoring force of the resilient portion 731, and the light source fixing ring 3 is restricted from rotating freely again.
