Within this range, the side light can intersect with the bottom light after focusing, making the overall lighting uniform, not only maximizing the illumination range, but also optimizing the brightness of the lighting, thereby improving the lighting effect. If it is greater than this range or less than this range, the light scattered at the bottom will not intersect or overlap with the side light. Although the former has a large lighting range, the brightness is not enough, and the latter has too large brightness and a small range, and the effect is poor.

[0033] The light adjustment component 4 includes a diffuser plate 403, a plurality of first focusing plates 401 and a second focusing plate 402. The focal lengths of the first focusing plates 401 and the second focusing plates 402 are determined according to the actual floor height, and the focal lengths are 20-50CM greater than the floor height, while the focal length of the diffuser plate 403 is close to the floor height, so that the focused light beam and the dispersed light beam can be evenly irradiated to the ground, and the irradiation range and effect are optimal.

[0034] Furthermore, an L-shaped slide groove 302 is provided on the front of the T-shaped column 102, a slider 303 adapted to the slide groove 302 is fixedly provided on one side of the inner wall of the movable ring 301, and a wear-resistant layer 310 is fixedly provided on the outer wall of the slider 303. The wear-resistant layer 310 is made of wear-resistant rubber to prevent the slider 303 from being worn. Two card grooves 311 are provided on one side of the outer wall of the T-shaped column 102, one of which is located at the top of the outer wall of the T-shaped column 102, and the other card groove 311 is located at the top of the outer wall of the T-shaped column 102. 11 is located at the bottom of the outer wall of the T-shaped column 102, a square groove 304 is opened on the side of the movable ring 301 near the slide groove 302, and a movable block 305 is movably arranged inside the square groove 304, and a clamping rod 306 is fixedly arranged on the side of the movable block 305 near the T-shaped column 102, and one end of the clamping rod 306 movably passes through the inner wall of one side of the square groove 304 and extends to the inside of one of the clamping grooves 311, and a pull rod 307 is fixedly arranged on the other side of the movable block 305, and one end of the pull rod 307 is movably arranged.

The diffuser plate 403 can be opened by the movable setting of the diffuser plate 403, and the lampshade assembly 2 is connected to the lamp holder assembly 1 through the connection assembly 3 by the setting of the connection assembly 3. The lampshade assembly 2 can move up and down. By rotating the movable ring 301, the slider 303 slides into the vertical groove of the slide groove 302, and then the movable ring 301 is slid upward, thereby driving the lampshade assembly 2 to slide upward, so that the bulb 5 and the support plate 103 are moved out of the lampshade assembly 2 through the opening of the diffuser plate 403, so that maintenance personnel can perform maintenance without disassembling the lampshade assembly 2. While facilitating maintenance for maintenance personnel, maintenance personnel do not need to hold the lampshade assembly 2, thereby improving the efficiency and safety of maintenance.

[0035] A fixing ring 2023 is arranged around the opening edge of the bottom end of the second annular cover 2022, and a rotating groove 2024 and a square groove 2025 are respectively provided on both sides of the bottom end of the fixing ring 2023, and a rotating block 2029 and a handle 2027 are respectively fixedly arranged on both sides of the diffuser plate 403, and the rotating block 2029 is rotatably connected to the inner wall of the rotating groove 2024 through a pin shaft, and the handle 2027 is adapted to the square groove 2025, and a second magnet 2028 is inlaid on the top end of the handle 2027, and a first magnet 2026 with opposite magnetic properties to the second magnet 2028 is inlaid on the top inner wall of the square groove 2025.

[0036] Secondly, a plurality of heat dissipation holes 107 distributed in a circular array are formed through the bottom end of the support plate 103, and the top end of the heat dissipation hole 107 extends through the inside of the T-shaped column 102 to the top end of the outer wall of the T-shaped column 102, and an insect-proof net 108 is fixedly arranged at the opening of the heat dissipation hole 107 close to one end of the T-shaped column 102. Through the arrangement of the plurality of heat dissipation holes 107 and the insect-proof net 108, the heat dissipation hole 107 can dissipate the heat inside the lampshade assembly 2 to prevent the bulb 5 from being damaged. At the same time, the insect-proof net 108 can prevent external mosquitoes from entering the inside of the lampshade assembly 2 and affecting the lighting effect of the bulb 5. An installation groove 104 is opened through, a receiving groove 105 is opened in the middle of the top of the installation plate 101, and a wire groove 106 is opened in the middle of the bottom inner wall of the receiving groove 105, and the bottom end of the wire groove 106 extends to the inner bottom end of the T-shaped column 102, and a sealing groove 6 is opened around the bottom opening of the movable ring 301, and the sealing groove 6 is adapted to the support plate 103, and a sealing strip 7 is arranged around the outer wall of the support plate 103, and the sealing strip 7 is fitted and connected with the inner wall of the sealing groove 6. Through the setting of the sealing strip 7, the sealing between the movable ring 301 and the support plate 103 can be improved to prevent external mosquitoes from entering the interior of the lampshade assembly 2.

[0037] Specific construction method: Step 1: During the corridor construction, reserve a mounting hole and a line connected to the light bulb 5 on the top wall; Step 2: Insert the mounting plate 101 into the mounting hole and fix it with bolts or expansion screws. Before fixing, pass the line through the receiving groove 105 and the wire groove 106; Step 3: Pull the pull rod 307 to drive the movable block 305 to move in the square groove 304, and compress the two return springs 308, and at the same time drive the clamping rod 306 to be flush with the inner wall of the movable ring 301, and then put the movable ring 301 and the upper lampshade 201 on the movable ring 301 into the T-shaped column 102, and clamp the slider 303 to the highest point inside the slide groove 302, and at this time, the clamping rod 306 is aligned with the clamping groove 311 at the top. After releasing the pull rod 307, the clamping rod 306 is pushed into the clamping groove 311 at the top and is stuck because the return spring 308 recovers its deformation, and then the support plate 103 is taken out, and the line is connected to the wiring place reserved on the support plate 103; Then, the support plate 103 is fixed to the bottom end of the T-shaped column 102 by screws. Since the support plate 103 is directly fixed to the bottom end of the T-shaped column 102, the movable ring 301 cannot be easily disassembled, and thus the lampshade assembly 2 cannot be easily disassembled, which plays a protective role to prevent it from being disassembled at will and causing losses. The heat dissipation holes 107 on the support plate 103 are aligned with the holes on the T-shaped column 102, and then the bulb 5 is screwed into the mounting hole reserved at the bottom of the support plate 103, and then the lower lampshade 202 is installed to the bottom of the upper lampshade 201 by screws or buckles, and finally the diffuser plate 403 is closed, so that the handle 2027 partially enters the interior of the square groove 2025, and the second magnet 2028 and the first magnet 2026 have opposite magnetic properties, and the handle 2027 is adsorbed.

[0038] Working principle of the present invention: During maintenance, the maintenance personnel climb to the vicinity of the device through a stepladder, and then pull the diffuser plate 403 downwards through the handle 2027, so that the second magnet 2028 and the first magnet 2026 are no longer adsorbed, so that the diffuser plate 403 opens, and then pulls the pull rod 307 to drive the movable block 305 and the clamping rod 306 to move away from the T-shaped column 102, and compresses the two return springs 308 to make one end of the clamping rod 306 disengage from the inside of the clamping groove 311 at the bottom, and then rotates the movable ring 301 to drive the slider 303 to slide into the vertical groove of the slide groove 302, and then pushes the movable ring upwards 301 and lampshade assembly 2, and the slider 303 slides upward inside the slide groove 302. When the slider 303 slides to the top of the slide groove 302, the clamping rod 306 is aligned with the clamping groove 311 at the top. At this time, the two reset springs 308 restore their deformation and push the movable block 305 to move toward the direction close to the T-column 102, thereby pushing the clamping rod 306 to be clamped into the clamping groove 311 at the top, and the movable ring 301 is clamped. At this time, the bulb 5 and the support plate 103 are both moved out of the lampshade assembly 2 from the opening of the diffuser plate 403, so as to facilitate the maintenance personnel to replace the bulb 5 or perform maintenance.

[0039] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, it is still possible for those skilled in the art to modify the technical solutions described in the aforementioned embodiments or to make equivalent substitutions for some of the technical features therein.
