The ends of the two rotating shafts 312 that are close to each other are respectively fixedly connected to the bottom sides of the hanging rod 2. The limiting plate 313 is fixed to the inner wall of the frame 311.

[0036] The hanging rod 2 and the long plate 3 are connected by a rotating part 31 and integrated together. When transported to the site for installation, there is no need to carry out the cumbersome installation operation of separating the classroom light and the hanging rod 2 on site, as is the case with traditional classroom lights. During installation, the hanging rod 2 only needs to be rotated from the folded state to the vertical state, which greatly simplifies the installation process and improves the installation efficiency.

[0037] Specifically, the rotating component 31 also includes a U-shaped limiting frame 315. The top of both ends of the frame 311 are provided with slots 316. The two ends of the limiting frame 315 are respectively inserted into the two slots 316. Magnets 317 are fixedly provided at both ends of the limiting frame 315.

[0042] Take the cover 61 and place it in the storage slot 32. Rotate the fixing strip 63 inside the cover 61 by hand to make the external thread of the cover 61 and the internal thread of the storage slot 32 threadedly connected, thus covering the storage slot 32 and preventing the contents of the storage slot 32 from being lost during transportation.

[0043] Specifically, the shielding member 6 also includes a limiting ring 62 for limiting the shielding cover 61, and the limiting ring 62 is fixedly sleeved on the outside of the shielding cover 61.

[0044] The limiting ring 62 can limit the position of the cover 61.

[0045] The LED 12 and the driver power supply are existing technologies, and the working principle of this part is also existing technology, which can be clearly understood by those skilled in the art, and will not be described in detail here.

[0046] Example 2, refer to Figures 1-10 This is the second embodiment of the present invention, which is based on the previous embodiment.

[0047] Specifically, two arc-shaped clamping plates 4 are fixedly installed on the top of the long plate 3, and the hanging rod 2 is clamped in the arc-shaped clamping plates 4.

[0048] During the lowering process of the boom 2, apply appropriate force to open the arc-shaped clamp 4 and insert it into the arc-shaped clamp 4 for fixation. The arc-shaped clamp 4 is made of plastic and has a certain degree of toughness. The specific material can be selected according to actual needs.

[0049] Specifically, both ends of the top of the long board 3 are provided with fasteners 5 for fixing the two hanging rods 2 when they are folded. The fasteners 5 include a fastening strap 51, a hook and loop fastener 52 and a loop fastener surface. One end of the fastening strap 51 is fixedly connected to the surface of the long board 3, the bottom of the hook and loop fastener 52 is fixedly connected to the surface of the long board 3, and the other end of the fastening strap 51 is sewn with a loop fastener surface. The hook and loop fastener 52 are bonded to the loop fastener surface.

[0050] Pull the fixing strap 51, pass it over the top of the rod 2, and fix it a second time by bonding the hook side 52 and the loop side of the hook and loop.

[0051] Specifically, the light fixture 1 also includes a ceiling cover 21, a bracket 23, and a cotter pin 24. The ceiling cover 21 is movably fitted onto the hanging rod 2. The top end of the hanging rod 2 is inserted into the bracket 23. A pin hole is opened at the top end of the hanging rod 2, and the cotter pin 24 passes through the pin hole. An installation hole is opened on the bracket 23, and a rubber sleeve 22 is fitted onto the hanging rod 2.

[0052] The bracket 23 is installed on the ceiling through mounting holes and bolts. First, the rubber sleeve 22 is put on the hanger rod 2, and then the ceiling cover 21 is put on the hanger rod 2. Then, the back plate 11 is lifted as a whole, and the top of the hanger rod 2 is inserted into the bracket 23. The cotter pin 24 passes through the pin hole of the hanger rod 2, and the two ends of the cotter pin 24 are bent to connect and fix the hanger rod 2 and the bracket 23. Then, the rubber sleeve 22 and the ceiling cover 21 are pulled upward so that the ceiling cover 21 covers the bracket 23, and the rubber sleeve 22 is positioned below the ceiling cover 21 for support. The inner diameter of the rubber sleeve 22 is slightly smaller than the diameter of the hanger rod 2 so that the rubber sleeve 22 is tightly fitted on the hanger rod 2 and will not slip.

[0053] Specifically, an LED lens is fixedly mounted on the surface of the LED bead 12.

[0054] The LED bead 12 is designed with an LED lens. The light emitted by the LED bead 12 is diffused through the LED lens, so that the light emitted by the entire lamp 1 starts to diffuse evenly in the first stage, thus achieving first-level anti-glare.

[0055] Specifically, a connecting rope 314 is fixedly installed on one side of the frame 311, and one end of the connecting rope 314 is fixedly connected to one side of the limiting frame 315.

[0056] The connecting rope 314 can prevent the limit bracket 315 from being lost.

[0057] When it is necessary to assemble the back plate 11, PC diffuser plate 13, grille 14 and outer frame 15, place the grille 14 inside the outer frame 15 for mounting, then place the PC diffuser plate 13 on top of the grille 14, and finally place the back plate 11 on top of the outer frame 15, align the threaded holes between the back plate 11 and the outer frame 15, and use screws to fix the outer frame 15 and the back plate 11 together, thus completing the assembly of the main body of the lamp 1.

[0058] By setting up the storage slot 32, the ceiling cover 21, cotter pin 24, rubber sleeve 22, and bracket 23 can be stored and placed in the storage slot 32. After placing them in the storage slot 32, take out the cover 61 and place it in the storage slot 32. Rotate the fixing strip 63 inside the cover 61 by hand so that the external thread of the cover 61 and the internal thread of the storage slot 32 are threadedly connected, thus covering the storage slot 32 and preventing the items in the storage slot 32 from being lost during transportation.

[0059] When the lifting rod 2 (which is a hollow structure with through holes at both the top and bottom for easy wiring) needs to be folded for transport, pull out the limiting bracket 315 inserted into the slot 316 by hand, rotate the lifting rod 2, and the lifting rod 2 will rotate through the pivot 312, so that the lifting rod 2 is laid down on the top of the long plate 3 in a folded state. During the process of laying down the lifting rod 2, use appropriate force to open the arc-shaped clamping plate 4 and insert it into the arc-shaped clamping plate 4. Finally, pull out the fixing strap 51, pass it over the top of the lifting rod 2, and fix it a second time by bonding the hook and loop sides of the Velcro 52 and the loop side of the Velcro.

[0060] When transported to the place of use, release the fixing strap 51 and use appropriate pulling force to make the lifting rod 2 leave the arc-shaped card plate 4. When the lifting rod 2 rotates to the vertical position, one side of the lifting rod 2 will be attached to the limiting plate 313. Then, the limiting frame 315 is inserted into the slot 316 of the frame 311 and magnetically fixed by the magnet 317 and the iron plate to limit the other side of the lifting rod 2 and prevent rotation.

[0061] Rotate the cover 61 to remove the ceiling cover 21, cotter pin 24, rubber sleeve 22, and bracket 23. The bracket 23 is installed on the ceiling through the mounting holes and bolts. First, put the rubber sleeve 22 on the hanger rod 2, then put the ceiling cover 21 on the hanger rod 2. Then, lift the back plate 11 as a whole and insert the top of the hanger rod 2 into the bracket 23. The cotter pin 24 passes through the pin hole of the hanger rod 2, and the two ends of the cotter pin 24 are bent to connect and fix the hanger rod 2 and the bracket 23. Then, pull the rubber sleeve 22 and the ceiling cover 21 upward so that the ceiling cover 21 covers the bracket 23, while the rubber sleeve 22 is positioned below the ceiling cover 21 for support. The inner diameter of the rubber sleeve 22 is slightly smaller than the diameter of the hanger rod 2 so that the rubber sleeve 22 can be tightly fitted on the hanger rod 2 and will not slip.

[0062] LED lenses are designed on LED beads 12. The light emitted from LED beads 12 is diffused by the LED lenses, making the light emitted by the entire lamp 1 diffuse evenly in the first stage, achieving the first level of anti-glare. In the second stage, the light emitted by the lamp 1 passes through PC diffuser plate 13. The optical performance of the diffuser plate is to fully scatter and diffuse the light, making the light more uniform and soft, achieving the second level of anti-glare. In the third stage, after the light has been fully scattered and diffused, it passes through grille 14 (grille 14 uses ABS aluminum plating process, which has good anti-glare effect and is resistant to yellowing). The light is cut off and controlled. The light is blocked by the electroplated grille 14 to form a protective angle, achieving excellent anti-glare effect and three-level anti-glare. In addition, the lamp adopts a rectangular grille 14 design in the direction of 1C90-C270 degrees, and the beam angle of the whole lamp reaches 110 degrees, making the light illumination of the classroom more uniform. The lamp 12 uses low blue light and high color rendering index 2835 lamp. The top of the back plate 11 is also equipped with a driver power supply, namely LED driver power supply (using bipolar flicker-free) for connecting the lamp 12 to the power supply.
