[0002] A lighting device is a device that uses a light source to generate light and propagate it to the area that needs illumination. Depending on the place of use and purpose, lighting devices can be divided into various types, such as indoor lighting devices, outdoor lighting devices, stage lighting devices, etc.

[0003] Screen light bars are lighting devices that hang above computer or laptop monitors. Designed specifically for modern office and study environments, they aim to protect the eyes and improve user comfort by providing a uniform, soft light source, reducing screen reflections and glare.

[0004] Currently, screen lights are usually fixed to the monitor using methods such as table clips.

[0033] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0034] Reference Figures 1-2This utility model provides an embodiment of a lighting device that is easy to install, including a fixing frame 1 for fixed connection. Two sets of fixing frames 1 are provided, symmetrically arranged left and right. A fixing groove 2 is formed on the inner side of each fixing frame 1, allowing it to be directly fitted onto the left and right corners above the screen. A limiting frame 3 for fixed connection is fixedly connected to the top of the fixing frame 1. A fixing sleeve 4 is fixedly connected to the inner side of the limiting frame 3. A sliding block 5 is slidably connected inside the fixing sleeve 4, and the inner side of the fixing sleeve 4 is shaped like a frustum. The sliding block 5 is shaped to match the inner frustum of the fixed sleeve 4. When the sliding block 5 moves outward along the fixed sleeve 4, the inclined side of the sliding block 5 will disengage from the inner wall of the inner frustum of the fixed sleeve 4. The inner side of the limiting frame 3 is elastically connected to the outer side of the sliding block 5 by a limiting spring 9. When the sliding block 5 is not under force, the limiting spring 9 will push the sliding block 5 inward toward the fixed sleeve 4. One end of the limiting spring 9 is fixedly connected to the inner side of the limiting frame 3, and the other end is fixedly connected to the outer side of the sliding block 5. The sleeve 4 has three sets of grooves 6, which are evenly distributed in a ring inside the grooves 6. A limiting ball 7 is slidably connected inside the groove 6, restricting the limiting ball 7 to slide only along the inner wall of the groove 6. The outer side of the limiting ball 7 contacts the inner wall of the side of the fixed sleeve 4. A limiting ring 8 is fixedly connected to the inner side of the sliding block 5. The outer circumference of the limiting ring 8 is slidably connected to the inner wall of the fixed sleeve 4 at a non-frustum location, restricting the sliding block 5 to slide only left and right along the inner wall of the fixed sleeve 4. The inner side of the sliding block 5 is connected to a connecting ring... A magnetic block 11 is fixedly connected to the ring 10. The magnetic block 11 is magnetic. An electromagnet 12 is fixedly connected to the inside of the limiting frame 3. When the electromagnet 12 is energized, it will generate a strong magnetic force. The electromagnet 12 is located inside the limiting spring 9. The magnetic block 11 is located inside the limiting spring 9. When the electromagnet 12 is energized, the strong magnetic force it generates will attract the magnetic block 11, causing the magnetic block 11 to move towards the electromagnet 12. A switch assembly is provided inside the limiting frame 3. The switch assembly is used to switch the electromagnet 12 on or off, so that the electromagnet 12 is energized or de-energized.

[0035] Reference Figures 2-3The switch assembly includes a switch box 13 for fixed connection. The outer periphery of the switch box 13 is fixedly connected to the inside of the limit frame 3. A button 15 is elastically connected to the inner wall of the bottom end of the switch box 13 via a pressing spring 14. When the button 15 is not subjected to force, the pressing spring 14 will push the button 15 upward. A connecting block 16 is fixedly connected to the bottom end of the button 15. The bottom end of the connecting block 16 is provided with two sets of connecting contact points 17, which are symmetrically arranged at the bottom end of the connecting block 16. Meanwhile, the connecting block 16 can connect the two sets of connecting contact points 17. The bottom of the connecting contact point 17 contacts the connecting seat 18. There are two sets of connecting seats 18, which are positioned opposite to the connecting contact point 17. The bottom of the connecting seat 18 is set on the inner wall of the bottom of the switch box 13. One set of connecting seats 18 is electrically connected to the electromagnet 12, and the other set of connecting seats 18 is connected to the power supply. When the connecting contact point 17 contacts the connecting seat 18, the electromagnet 12 will be energized, causing the electromagnet 12 to generate a strong magnetic force.

[0036] Reference Figure 1 , Figure 2 and Figure 4 The sliding block 5 has a sliding pin 19 inside which it is fixed. The outer periphery of the pin 19 is slidably connected to the inner side of the fixing sleeve 4 and the inner periphery of the pin 19 is slidably connected to the inside of the sliding block 5. A limiting annular groove 20 is formed on the outer periphery of the pin 19. The inner side of the limiting ball 7 is engaged in the inner side of the limiting annular groove 20 to fix the pin 19. An adjustment component is slidably connected to the outer periphery of the pin 19. The adjustment component is used to adjust the distance between the two sets of fixing brackets 1. A lamp tube 30 is provided inside the adjustment component. When the lamp tube 30 is turned on, it can produce soft and uniform light on the screen.

[0037] Reference Figures 4-5The adjustment assembly includes a limiting cylinder 21, with a locking pin 19 slidably connected inside the limiting cylinder 21. A sliding block 22 is elastically connected inside the limiting cylinder 21 via a compression spring 23. When the sliding block 22 is not under force, the compression spring 23 pushes the sliding block 22 inward. The outer side of the sliding block 22 is fixedly connected to the inner side of the locking pin 19. Sliding the sliding block 22 will drive the locking pin 19 to move. A groove 24 is provided on the outer circumference of the limiting cylinder 21. Four sets of grooves 24 are evenly distributed in a ring around the outer circumference of the limiting cylinder 21. A slider 25 is slidably connected inside the groove 24. The groove 24 and the slider 25 allow the limiting cylinder 21 to move. 1. The rotating ring 26 rotates in the same direction as the slider 25. The rotating ring 26 is fixedly connected to the outer circumference of the slider 25. The connecting seat 27 is rotatably connected to the inner side of the rotating ring 26. The limiting cylinder 21 is slidably connected to the inner side of the rotating ring 26 and the connecting seat 27. The connecting seat 27 has a threaded groove 28 on its inner side. The threaded block 29 is threadedly connected to the inside of the threaded groove 28. When the threaded block 29 rotates, it slides left and right along the inner wall of the threaded groove 28. The outer side of the threaded block 29 is fixedly connected to the inner side of the limiting cylinder 21. When the limiting cylinder 21 rotates, it can drive the threaded block 29 to rotate. The inner side of the connecting seat 27 is set on the outer side of the lamp tube 30.

[0038] Reference Figure 1 and Figure 6 The inner side of the fixing frame 1 is provided with a slot 31, and a block 32 is slidably connected to the inner side of the slot 31. A counterweight column 33 is slidably connected to the outer periphery of the block 32. The counterweight column 33 is used to balance the weight of the lamp tube 30, so that the screen is subjected to more even force. A limit groove 34 is provided inside the counterweight column 33. A rectangular block 36 is elastically connected to the inner side of the limit groove 34 through a return spring 35. When the rectangular block 36 is not under force, the return spring 35 will push the rectangular block 36 outward. The outer side of the rectangular block 36 is fixedly connected to the inner side of the block 32. The left and right sliding of the rectangular block 36 will drive the block 32 to move simultaneously.

[0039] Working principle: When installing and removing the fixed lamp tube 30, first, place one side of the fixing bracket 1 onto one corner of the screen. Then, insert the pin 19 on one side of the lamp tube 30 into the inside of the fixing sleeve 4 of the fixing bracket 1. When the pin 19 contacts the limiting ball 7, the limiting ball 7 blocks the pin 19 from inserting into the inner side of the multiple sets of limiting balls 7. At this time, the pin 19 will push the sliding block 5 outward. The sliding block 5 moves outward and compresses the limiting spring 9. At this time, a gap is created between the sliding block 5 and the truncated cone of the fixing sleeve 4. The limiting ball 7 will move into the gap under the push of the pin 19, maintaining contact with the inner wall of the fixing sleeve 4. When the gap between the multiple sets of limiting balls 7 is larger than the diameter of the pin 19, the pin 19 passes through the limiting ball 7. When the ball 7 contacts the limiting ring groove 20, the sliding block 5 is not under force, the limiting spring 9 pushes the sliding block 5 inward, and the fixing sleeve 4 re-presses the limiting ball 7, inserting the limiting ball 7 into the limiting ring groove 20. At this time, the lamp tube 30 is stably fixed. Then, the fixing bracket 1 on the other side is placed on the other corner of the screen, and the other side pin 19 is inserted into the fixing sleeve 4 to complete the installation. Press the button 15, and the button 15 drives the connecting block 16 to move downward. The connecting block 16 drives the connecting contact point 17 to contact the connecting seat 18. At this time, the electromagnet 12 is energized and generates magnetism, attracting the magnetic block 11 and driving the magnetic block 11 to move outward, so that the limiting ball 7 no longer clamps the pin 19, thus making it easy to remove the lamp tube 30. When you want to easily adjust the distance between the two sides of the lamp tube 30, rotate the rotating ring 26. Rotating the ring 26 will cause the limiting cylinder 21 to rotate, and the limiting cylinder 21 will cause the threaded block 29 to rotate. The threaded block 29 will cause the inner wall of the threaded groove 28 to slide inward, causing the limiting cylinder 21 to move inward. The inward movement of the limiting cylinder 21 will cause the pin 19 to move inward through the compression spring 23, thereby easily adjusting the distance between the two sides of the lamp tube 30 and the fixing frame 1. This allows the screen hanging light to be used with screens of different frame widths. At the same time, the limiting cylinder 21 compresses the compression spring 23, which can make the fixing frame 1 and the screen frame clamp together, making the clamping more stable. When the lamp tube 30 hangs on the screen and causes the screen to tilt forward, the rectangular block 36 is moved inward, causing the two side blocks 32 to retract into the limiting groove 34 and compress the reset spring 35, so that the blocks 32 align with the slot 31. The rectangular block 36 is released, the reset spring 35 releases its elasticity, and pushes the blocks 32 into the slot 31. At this time, the weight of the screen is balanced, preventing the screen from tipping over.

[0040] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
