At night, when the room environment is relatively dim, the user only needs to start the electric motor 4 to drive the bidirectional screw rod 5 to rotate clockwise, so that the two threaded sleeves 6 are close to each other. At this time, under the action of the connecting rod 7, the two hemispherical lampshades 8 will close into a sphere, thereby covering the blue light anti-myopia lighting lamp 3 inside.

[0027] At this time, the fabric sunshade cover 9 can effectively scatter light, reduce direct light and the hardness of shadows. When light passes through the fabric sunshade cover 9, it will become more dispersed and soft, reducing the sharpness of light spots and shadows, thereby making the entire lighting effect more uniform and natural, thereby avoiding light glare and being more conducive to use.

[0028] See also Figure 1 , Figure 4 , Figure 5 and Figure 6 A mounting groove 11 is provided on the top of the base 2, and a sleeve 12 and a rotating shaft 13 are rotatably installed inside the mounting groove 11. A plug rod 14 is fixedly connected to the back of the lamp holder 1, a first gear 15 is installed on the outer surface of the rotating shaft 13, and a second gear 16 is installed on the outer surface of the sleeve 12. A turntable 17 is fixedly connected to the top of the rotating shaft 13. The first gear 15 and the second gear 16 are meshed for transmission, and the plug rod 14 is plugged into the sleeve 12. When in use, the user only needs to rotate the turntable 17, and the sleeve 12 can be driven to rotate under the cooperation of the meshing transmission of the first gear 15 and the second gear 16, so as to adjust the orientation angle of the lamp holder 1, so as to be suitable for different situations, improve the flexibility of use, and have good practicality.

[0029] It should be noted that the outer surfaces of the plug rod 14 and the sleeve 12 are provided with a plurality of sockets 18, and the inside of the sockets 18 is connected with pins 19. By setting the sockets 18 and the pins 19, the user can adjust the horizontal height of the lamp head 1 by changing the way the pins 19 are inserted into the holes, which is more convenient.

[0030] It should be understood that the hemispherical lampshade 8 is made of transparent plastic, and a semicircular groove 20 is provided at the bottom of the hemispherical lampshade 8 to prevent the blue light anti-myopia lighting lamp 3 from being clamped by its lamp post.

[0031] In addition, the base 2 is made of metal, and a magnetic plate 22 for shielding is provided on the front of the base 2. By providing the magnetic plate 22, the effect of shielding the first gear 15 and the second gear 16 is achieved, reducing the probability of debris getting stuck in the meshing portion.

[0032] The working principle of the above embodiment is:

[0033] The anti-myopia desk lamp for high school students that is easy to adjust can be used at night when the room environment is dim, and the user only needs to start the electric motor 4 to drive the bidirectional screw rod 5 to rotate clockwise, so that the two threaded sleeves 6 are close to each other. At this time, under the action of the connecting rod 7, the two hemispherical lampshades 8 will be closed into a sphere, so that the blue light anti-myopia lighting lamp 3 is covered inside. At this time, the fabric shading sleeve 9 can effectively scatter light, reduce the direct light and the hardness of the shadow. When the light passes through the fabric shading sleeve 9, it will become more dispersed and soft, reducing the sharpness of the light spot and the shadow, so that the entire lighting effect is more uniform and natural, thereby avoiding the glare of the light and being more conducive to use. In addition, when using it during the day, the user only needs to restart the electric motor 4 and rotate the controller output shaft counterclockwise, so that the two threaded sleeves 6 are away from each other, so that the two hemispherical lampshades 8 no longer cover the blue light anti-myopia lighting lamp 3, thereby ensuring its blue light eye protection effect.
