[0026] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0027] The utility model provides a technical solution:

[0028] See also Figures 1 to 5 , an exhibition lighting device for exhibition halls, comprising a lampshade 1, a glare reduction component 2 is provided inside and outside the lampshade 1, and the glare reduction component 2 comprises a mounting seat 21 rotatably connected inside the lampshade 1;

[0029] A bulb 22 is threadedly connected to the lower side of the mounting base 21, and both ends of the mounting base 21 pass through the lampshade 1. Gears 23 are fixedly connected to both ends of the mounting base 21, and racks 24 are meshed on the outer sides of the two gears 23. The upper sides of the two racks 24 are fixedly connected to first electric push rods 25, and the top ends of the two first electric push rods 25 are fixedly connected to the outer side of the lampshade 1. A reflector 26 is clamped inside the lampshade 1, and a light-transmitting sheet 27 is fixedly connected to the lower side of the lampshade 1.

[0030] An adjusting component 28 is provided inside the lampshade 1 . The adjusting component 28 includes a reflective layer 281 laid on the inner wall of the lampshade 1 . A soft board 282 is fixedly connected to the upper side of the reflective plate 26 .

[0031] A plurality of support plates 283 are fixedly connected to the outer side of the soft board 282. A plurality of movable grooves 284 are opened on the surface of the lampshade 1. The plurality of support plates 283 are respectively inserted into the plurality of movable grooves 284. The plurality of movable grooves 284 and the plurality of support plates 283 are arranged in a ring array.

[0032] The inner top of the lampshade 1 is fixedly connected with a second electric push rod 286 , and the bottom end of the second electric push rod 286 is fixedly connected with a support plate 285 . The surface of the support plate 285 moves downward and is pressed and contacted with the upper side of the soft board 282 .

[0033] Two cleaning components 3 are arranged on the outer side of the lampshade 1 .

[0034] By adopting the above technical solution, first, after the light bulb 22 fixed on the mounting seat 21 is started, the direct light generated by it will directly shine on the reflector 26, and the light will be reflected by the reflector 26, so that the light will be radiated out through the light-transmitting sheet 27, and the surrounding light will be reflected by the reflective layer 281 inside the lampshade 1, and then also radiated out through the light-transmitting sheet 27, and the reflected light will be dispersed. After the second electric push rod 286 is started to push the support plate 285 downward, the support plate 285 will squeeze the soft plate 282, driving the reflector 26 under the soft plate 282 to be convex, causing the light to The range of light dispersion is increased. If the first electric push rod 25 is started to push the rack 24 downward, the rack 24 is meshed with the gears 23 at both ends of the mounting base 21. When the rack 24 moves downward, the gear 23 will start to rotate and drive the mounting base 21 and the bulb 22 installed thereon to flip. At this time, the light generated by the bulb 22 will directly pass through the light-transmitting sheet 27. Since the irradiation angle of the bulb 22 can be adjusted, when the light irradiates the reflector 26 inside the lampshade 1, the reflected light will be dispersed to avoid the glare caused by the light irradiation and cause discomfort to the viewer, while also ensuring the irradiation intensity of the light.

[0035] Specifically, Figure 4 As shown, the cleaning component 3 includes a threaded rod 31 fixedly connected to the lower side of the rack 24, and the outer sides of the two threaded rods 31 are both threadedly connected with threaded sleeves 33.

[0036] Two fixing seats 32 are fixedly connected to the outer side of the lampshade 1 , and a limiting ring 34 is fixedly connected to the outer side of the threaded sleeve 33 . The fixing seats 32 are sleeved on the outer side of the threaded sleeve 33 through the limiting ring 34 .

[0037] A cleaning strip 35 is fixedly connected to the lower side of the threaded sleeve 33 . A through hole 36 is formed on the surface of the cleaning strip 35 . The through hole 36 is communicated with the threaded sleeve 33 .

[0038] The thread directions of the two threaded rods 31 are opposite, and the outer sides of the threaded rods 31 are threadedly connected with threaded sleeves 33 .

[0039] By adopting the above technical solution, firstly, when the first electric push rod 25 pushes the rack 24 downward, the threaded rod 31 below the rack 24 will also move downward and pass through the threaded sleeve 33, so that the threaded sleeve 33 rotates inside the fixing seat 32 through the limit ring 34. While the threaded sleeve 33 rotates, since the thread directions of the two threaded rods 31 are the same, the rotation directions of the two threaded sleeves 33 will also be the same, and the threaded rod 31 will gradually pass through the through hole 36 on the surface of the cleaning strip 35. When the two threaded sleeves 33 rotate, the two cleaning strips 35 will be driven to rotate and finally contact each other in the process of cleaning the surface of the transparent optical disc. After the threaded rod 31 moves upward, the two cleaning strips 35 will gradually move away and face opposite directions. Since the mounting seat 21 will drive the cleaning strips 35 carried by the two threaded rods 31 to rotate during the flipping process, the cleaning strips 35 will clean the impurities attached to the surface of the transparent sheet 27, thereby ensuring the cleanliness of the surface of the transparent sheet 27 and avoiding the impurities from blocking the light.

[0040] Working principle: First, after the bulb 22 above the mounting base 21 is turned on, the direct light will directly shine on the reflector 26, and then the light will be reflected by the reflector 26 and then shine out through the light-transmitting sheet 27, while the surrounding light will be reflected by the reflective layer 281 inside the lampshade 1, and then also shine out through the light-transmitting sheet 27 and disperse the light. In this process, the second electric push rod 286 pushes the support plate 285 to squeeze the soft plate 282, driving the reflector 26 under the soft plate 282 to be convex. After the first electric push rod 25 is started to push the rack 24 downward, the gear 23 will start to rotate and drive the mounting seat 21 and the bulb 22 installed thereon to flip, so that the light will directly pass through the light-transmitting sheet 27. During this process, the threaded rod 31 under the rack 24 will also move downward, and when passing through the threaded sleeve 33, it will drive the threaded sleeve 33 to rotate inside the rotating fixed seat 32 through the limiting ring 34. While the threaded sleeve 33 rotates, it will drive the two cleaning strips 35 to rotate, and finally clean the surface of the light-transmitting disc.

[0041] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, ordinary technicians in this field should understand that they can still modify the technical solutions recorded in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not make the essence of the corresponding technical solution deviate from the scope of the technical solution of the embodiments of the utility model.
