The classroom eye protection lamp can be connected to the rear cover plate 3 and the hanging structure by bolts. The classroom eye protection lamp is installed on the ceiling in the classroom, and a fixing plate 10 is fixedly connected to the inner side of the lamp frame 1.
[0027] See also Figure 1 , Figure 2 , Figure 4 and Figure 5 A sliding groove 17 is provided at the lower end of the fixed plate 10. The sliding groove 17 is T-shaped and the number is set to be several. A sliding plate 11 is slidably arranged in the sliding groove 17. The sliding plate 11 is pulled out from one side of the fixed plate 10 or embedded in the fixed plate 10 by sliding. Conductive contacts 18 are fixedly arranged on both sides of the sliding plate 11. A light bar 9 is fixedly connected to the lower end of the sliding plate 11. The light bar 9 is electrically connected to the conductive contact 18 and connected to the circuit. When the circuit is connected, the current flows through the light bar 9 through the conductive contact 18. The light bar 9 starts to generate light and cooperates with the light-transmitting plate 2 to form an eye-protecting light source. When the light bar 9 is damaged and needs maintenance or replacement, the damaged light bar 9 can be pulled out through the sliding plate 11 alone. A handle 24 is fixedly connected to one side of the sliding plate 11 to facilitate the pulling out and insertion of the sliding plate 11.
[0028] See also Figure 1 , Figure 3 and Figure 4 The upper end surface of the rear cover plate 3 is rotatably connected with a lifting mechanism 4 at the midpoint. The lifting mechanism 4 includes a rotating rod 402, which is rotatably connected to the rear cover plate 3.

A lifting plate 401 is threadedly sleeved on the lower end of the rotating rod 402. The lifting plate 401 is located at the lower end of the rear cover plate 3.

Both sides of the upper end surface of the conductive touch plate 25 are fixedly connected with a No. 2 spring 19, which is used to provide elastic force to the conductive touch plate 25, so that after the bottom plate 13 moves downward to the maximum distance, the conductive touch plate 25 and the conductive contact piece 18 are elastically contacted to avoid deformation of the contact surface due to excessive force between them, and to ensure that the conductive touch plate 25 and the conductive contact piece 18 are closely fitted to avoid poor contact.
[0031] The bottom plate 13 is driven up by the lifting mechanism 4 to make the conductive contact plate 25 break away from the contact with the conductive contact piece 18, so that when the sliding plate 11 is pulled out, the friction between the conductive contact plate 25 and the conductive contact piece 18 is avoided, and additional wear during maintenance is avoided. The upper end surface of the conductive touch plate 25 is fixedly connected to the midpoint with a contact rod 21, and the upper end of the limit plate 15 is fixedly connected to a fixed brush 16. The limit plate 15 and the fixed brush 16 are both slidably sleeved with the contact rod 21. The conductive touch plate 25 and the fixed brush 16 are electrically connected to the contact rod 21.

[0036] The light bar 9 is connected to the circuit through the conductive contact 18, the conductive touch plate 25, the touch rod 21 and the fixed brush 16 to form a pathway. When maintaining the classroom eye protection lamp, the handle 403 is rotated to make the lifting plate 401 drive the bottom plate 13 to move upward, so that the conductive touch plate 25 is separated from the contact with the conductive contact 18, avoiding the friction between the conductive touch plate 25 and the conductive contact 18, and pressing the telescopic block 503 to make the connecting plate 23 drive the protrusion 20 to separate from the fixed groove 22, so as to remove the mounting plate 6, pull the handle 24, and pull out the sliding plate 11, so as to take out the light bar 9 that needs maintenance or replacement separately. Otherwise, the light bar 9 is inserted back for installation, and the upper ventilation groove 7, the inner ventilation groove 12 and the lower ventilation groove 8 cooperate so that the airflow can blow away the heat on the upper and lower end faces of the light bar 9 during the flow, thereby improving the heat dissipation capacity.
