Description

Technical Field

[0001] This utility model relates to the field of eye-protection classroom lights, specifically an anti-glare LED eye-protection classroom light. Background Technology

[0002] LED eye-protection classroom lights are widely used in classrooms due to their good anti-glare effect. Their structure is usually rectangular. These eye-protection classroom lights include a heat dissipation lamp housing and an LED lamp located inside the heat dissipation lamp housing. Then, an anti-glare structure (such as a transparent plate or / and a grid plate) is installed inside the lamp housing to reduce the light intensity and prevent the light from shining directly on people in the room.

[0003] A search revealed that utility model CN212226801U discloses an anti-glare micro-prismatic eye-protecting classroom light, comprising a lampshade, a mounting structure, and an anti-glare structure. The lampshade has an internal upper partition, symmetrically positioned mounting platforms on both sides of its upper surface, and a conduit at the wire outlet on the upper surface, with an insulating ring on the outer arc surface of the conduit. The mounting structure is mounted on the upper surface of the corresponding mounting platforms. The anti-glare structure is located at the lower interior of the lampshade and on the bottom surface of the partition. It also includes a control switch assembly located on the right side of the upper surface of the lampshade, with its input terminal electrically connected to an external power source. This anti-glare micro-prismatic eye-protecting classroom light is suitable for external mounting bases of different sizes, and can reduce light intensity through multiple reflections, minimizing glare and allowing the light to diffuse throughout the classroom, further protecting the eyes of occupants. It also accelerates the heat dissipation efficiency of the LED tube.

[0004] However, the above-mentioned existing technologies still have shortcomings in use: the above-mentioned eye-protecting classroom lights with anti-glare function use LED lights as light sources. When LED lights are working, they generate a lot of heat and are very bright, which puts high demands on the heat dissipation of the lampshade. However, due to the large air flow of people indoors, the outer surface of the lampshade (especially the top wall) will be covered with a thick layer of dust in a short time. The dust will affect the heat dissipation of the lampshade. If the heat dissipation efficiency is low during the long-term operation of the LED lights, it will reduce the lifespan of the LED lights. Moreover, the existing lampshades are usually installed at high places, which is inconvenient to clean.

[0005] Therefore, this utility model provides an anti-glare LED eye-protection classroom light. Utility Model Content

[0006] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide an anti-glare LED eye-protection classroom light to solve the problems mentioned in the background technology.

[0024] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0025] Please see Figures 1 to 4This utility model provides a technical solution: an anti-glare LED eye-protection classroom light, including a lamp body 1. The lamp body 1 includes a rectangular heat dissipation shell 11, which houses an LED light source and an anti-glare structure. The anti-glare structure can adopt the structure mentioned in the patent documents in the background art. A wiring conduit 111 is fixedly connected to the top of the heat dissipation shell 11, and the wiring connecting the LED light source passes through the wiring conduit 111 and connects to external wiring. A row of side heat dissipation fins 112 is provided on both sides of the heat dissipation shell 11, which can accelerate the dissipation of heat absorbed by the heat dissipation shell 11.

[0026] In this technical solution, the wiring conduit 111 is set at one end close to the heat dissipation shell 11. A slotted frame 2 is fixedly connected to the top of the heat dissipation shell 11. The slotted frame 2 serves to connect and fix the heat dissipation shell 11. Specifically, each of the two free ends of the slotted frame 2 is fixedly connected to a connecting plate 21 that is fixedly connected to both ends of the heat dissipation shell 11.

[0027] Furthermore, a rotating shaft 3 parallel to the heat dissipation housing 11 is provided inside the slot frame 2. The rotating shaft 3 is located above the heat dissipation housing 11. Specifically, positioning sleeves 22 are welded to both sides of the slot frame 2 and fitted onto the outside of the rotating shaft 3. A bearing 6 is provided between the positioning sleeve 22 and the rotating shaft 3. At least one cleaning plate 4 is fixedly connected to the outer peripheral wall of the rotating shaft 3. The cleaning plate 4 is parallel to the rotating shaft 3. In this embodiment, there are two cleaning plates 4. When the rotating shaft 3 rotates, the cleaning plates 4 will clean the top of the heat dissipation housing 11 and remove the accumulated dust on the top of the heat dissipation housing 11.

[0028] The cleaning plate 4 specifically comprises a positioning plate 41 and a brush strip 42 adhered to one side of the positioning plate 41. One side of the positioning plate 41 is fixedly connected to the outer peripheral wall of the rotating shaft 3. Because the brush strip 42 is soft and has good toughness, it can cover the upper surface of the heat dissipation shell 11. It should be noted that a row of top heat dissipation fins can be provided on the top of the heat dissipation shell 11 as needed to further improve its heat dissipation effect. The brush strip 42, during its movement, can enter between adjacent top heat dissipation fins, still effectively cleaning the dust on the top of the heat dissipation shell 11. In specific implementation, a control motor and controller for controlling the rotation of the rotating shaft 3 can be installed on one side of the slotted frame 2 as needed, facilitating electric control of the rotating shaft 3 via remote control.

[0029] In this embodiment, a gear 7 is fixedly sleeved on one end of the rotating shaft 3, and a toothed plate 8 that meshes with the gear 7 is provided on one side of the slotted frame 2. The toothed plate 8 and the slotted frame 2 are slidably connected vertically. When the toothed plate 8 moves up and down, it can drive the gear 7 to rotate, which in turn can drive the rotating shaft 3 to rotate. Specifically, a guide sleeve can be welded to one side of the slotted frame 2 and sleeved on the outside of the toothed plate 8. The toothed plate 8 can slide up and down under the guidance of the guide sleeve. A pull ring 81 is welded to the bottom of the toothed plate 8. This pull ring 81 is a handheld component. When maintenance personnel clean and maintain the large number of lamps 1 inside the chamber, they only need to climb up and pull the pull ring 81 up and down to clean the top of the heat dissipation shell 11.

[0030] Furthermore, a pad 23 near the bottom is welded to one side of the slotted frame 2, and a pressure plate 82 located above the pad 23 is welded to the top of the toothed plate 8. A return spring 9 is provided between the pressure plate 82 and the pad 23. When the toothed plate 8 is pulled down, the pressure plate 82 will also descend, compressing the return spring 9. When the toothed plate 8 is released, the return spring 9 will return to its original position and drive the toothed plate 8 to move upward and reset via the pressure plate 82. This arrangement allows operators to control the up and down movement of the toothed plate 8 from the ground by holding a lever with a hook at the top, without having to climb. To prevent the return spring 9 from bending and deforming during compression, a limiting rod that passes through the return spring 9 can be welded to the bottom of the pressure plate 82, with the limiting rod passing through the pad 23.

[0031] In this embodiment, the top of the slot frame 2 is detachably connected to the mounting plate 5. The mounting plate 5 is a rectangular plate structure with mounting holes near both ends. When in use, the mounting plate 5 is fixed to the ceiling wall of the room with screws. When the lamp body 1 needs to be inspected, the slot frame 2 and the mounting plate 5 can be separated, which makes it convenient to inspect the lamp body 1 on the ground.

[0032] Specifically, a lifting ring 51 and ear plates 52 located on both sides of the lifting ring 51 are fixedly connected to the middle of the bottom of the mounting plate 5. A hook 25 is fixedly connected to the middle of the top of the crossbar 24 on the slot frame 2. The hook 25 and the lifting ring 51 are hooked together. This arrangement allows the lamp body 1 to have an auxiliary suspension function when docking and separating from the mounting plate 5, making it convenient for the lamp body 1 and the mounting plate 5 to dock and separate. Among them, the crossbar 24 is fitted with a sliding sleeve 101 located on both sides of the hook 25. An L-shaped hanging plate 1011 is welded to the top of the sliding sleeve 101. An insertion hole 521 is opened on one side of the ear plate 52. When the sliding sleeve 101 moves laterally until one end of the L-shaped hanging plate 1011 enters the insertion hole 521, the slot frame 2 is in a state of fixed suspension on the mounting plate 5. When in use, an auxiliary locking bolt can be screwed through the top of the sliding sleeve 101. When the auxiliary locking bolt is tightened, one end of it will press against the crossbar 24, at which time the sliding sleeve 101 and the crossbar 24 can be locked.

[0033] Working principle: When regularly cleaning a large number of lamps 1 in the classroom, the maintenance personnel hold the lever and hook the pull ring 81, then pull it down. The toothed plate 8 descends, the gear 7 rotates, the return spring 9 is compressed, the rotating shaft 3 rotates, the cleaning plate 4 follows the movement, and the brush strip 42 circulates to clean the top of the heat dissipation shell 11. Then, the pull ring 81 is released, the return spring 9 returns to its original position, the toothed plate 8 is pushed upward, the rotating shaft 3 flips, and the brush strip 42 continues to circulate to clean the top of the heat dissipation shell 11. At this time, a large amount of accumulated dust on the top of the heat dissipation shell 11 can be effectively cleaned, ensuring that the heat dissipation shell 11 dissipates heat normally.

[0034] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
