[0002] Light therapy is a treatment method that uses artificial or natural light sources to prevent and treat diseases and promote recovery. Light therapy mainly includes ultraviolet therapy, visible light therapy, infrared therapy and laser therapy, and is a common method of physical factor treatment. Light therapy uses the energy it carries when penetrating the human body to convert it into biological energy that different tissues of our body are sensitive to and can use, thereby achieving a therapeutic effect on related diseases. Its three major treatment areas are tissue repair, wound healing, immune regulation, chronic inflammation, allergic inflammation and pain relief.

[0037] Working principle:

[0038] a. When adjusting the angle of the therapy lamp head 12, the first screw rod 7 can be driven to rotate by turning the adjustment knob 8. The first screw rod 7 is threadedly connected to the threaded sleeve 6, so that the rotation of the first screw rod 7 can drive the threaded sleeve 6 to move up and down. The threaded sleeve 6 is movably connected to the therapy lamp head 12 through the adjustment member 5, so that the up and down movement of the threaded sleeve 6 can drive the change of the output angle of the therapy lamp head 12, so that the output light of the six therapy lamp heads 12 can be gathered to the same area;

[0039] b. The horizontal angle of the mounting plate 2 can be fixed by the clamping connection between the limiting shaft 35 and the limiting hole 40. When adjusting the horizontal angle of the mounting plate 2, the limiting shaft 35 is separated from the limiting hole 40 by applying a pulling force to the pull ring 39. At this time, the mounting plate 2 can be rotated, so that the angle of the mounting plate 2 can be adjusted. After the adjustment is completed, the pulling force on the pull ring 39 is cancelled, and the limiting shaft 35 is clamped into the limiting hole 40 again under the elastic force of the buffer spring 38;

[0040] c. When adjusting the height of the therapy lamp head 12, the second screw 23 can be driven to rotate by rotating the lifting knob 24. The second screw 23 is threadedly connected to the lifting block 21. The lifting block 21 slides in the device groove 28, so that the rotation of the second screw 23 can drive the lifting block 21 to move upward, thereby realizing the adjustment of the height of the therapy lamp head 12.
