DETAILED DESCRIPTION

[0025] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all the embodiments.

[0026] Please refer to Figures 1-5 As shown in the figure, a glare-proof LED lamp based on a multi-stage light shielding structure comprises a shell 1, the shell 1 is provided with an LED light source 4, a diffusion plate 5 and a grid 6 are fixedly connected at the light outlet of the shell 1, a plurality of light shields 2 are arranged along the circumference of the light outlet of the shell 1, a connecting plate 8 is rotatably connected to one side of the light shield 2, the connecting plate 8 is magnetically fixed to the shell 1, and two adjacent light shields 2 are connected by an elastic telescopic cover 3. Specifically, the diffusion plate 5 is located on the side of the grid 6 close to the light source.

[0027] Under the action of the diffusion plate 5, the light is more uniform, the high-brightness area is reduced, and the glare caused by the local strong light to the human eye is avoided; under the action of the grid 6, the human eye is prevented from directly contacting the exposed light source, so as to reduce the direct glare. In addition, the light source is further shielded by the light shield 2, so that it does not directly enter the field of view of the human eye, and the glare-proof effect is further improved. By adopting the rotatable light shield 2, the light can be accurately controlled according to the requirements, and the light distribution is optimized. At the same time, under the action of the elastic telescopic cover 3, the light leakage between the two light shields 2 is avoided, and the glare-proof effect is improved. The connecting plate 8 is connected to the shell 1 in a magnetically fixed manner, so that it is more convenient to disassemble and assemble.

[0028] In order to adjust the light shielding angle of the light shield 2, the connecting plate 8 and the light shield 2 are rotatably connected by a damping hinge 10. By adopting the damping hinge 10, the light shield 2 can be fixed at any angle.

[0029] In order to avoid the position of the connecting plate 8 from deviating, a limiting block 7 is fixedly connected to the outside of the shell 1, a limiting groove matched with the limiting block 7 is formed in the inside of the connecting plate 8, a first magnet 9 is fixedly connected in the limiting groove, and the limiting block 7 is made of ferromagnetic material. The connecting plate 8 is positioned under the cooperation of the limiting block 7 and the limiting groove, the assembly effect of the two is improved, and the position of the connecting plate 8 is prevented from deviating.

[0030] In some embodiments, the light exit port of the shell 1 is rectangular, and the length of the light shielding plate 2 is adapted to the side length of the rectangular light exit port. By setting the light shielding plate 2 consistent with the side length of the light exit port, the mutual interference between the light shielding plates 2 is avoided, and the light shielding plate 2 in each direction can be independently adjusted to control the light.

[0031] In some embodiments, the outer side of the light shielding plate 2 is hingedly connected with a support rod 14, and the end of the support rod 14 away from the light shielding plate 2 is rotationally connected with a second tooth plate 12.

[0032] Specifically, the second tooth plate 12 is fixedly connected with a second magnet 13, and the first tooth plate 11 is a ferromagnetic material.

[0033] By setting the support rod 14 to assist the support of the light shielding plate 2, the stability of the light shielding plate 2 is further improved. When adjusting the inclination angle of the light shielding plate 2, the light shielding plate 2 is rotated to the required inclination angle, and then the support rod 14 is rotated to make the second tooth plate 12 engage with the first tooth plate 11, and the first tooth plate 11 is magnetically fixed with the second tooth plate 12 through the second magnet 13.
