Description
Technical Field
[0001] This utility model belongs to the field of LED fluorescent lamp technology, and specifically relates to an LED fluorescent lamp. Background Technology
[0002] As one of the core products in the LED lighting field, LED fluorescent lamps use LED light strips composed of LED light bead arrays as the core light source. Compared with traditional T8 and T5 fluorescent lamps, their energy consumption can be reduced by 30%-50%, and their service life can be extended to 50,000-80,000 hours (the service life of traditional fluorescent lamps is usually only 10,000-20,000 hours). They also do not contain harmful heavy metals such as mercury and lead, avoiding the environmental risks of harmful substance leakage when traditional fluorescent lamps break. At the same time, LED fluorescent lamps have no start-up delay and no flicker, and the color rendering index (Ra) can generally reach 80 or above, which can more realistically reproduce the colors of objects and effectively reduce visual fatigue. They are widely used in uniform lighting in office areas, merchandise displays in shopping malls, local lighting in corners of homes, and basic lighting in public corridors.
[0003] However, the transparent lampshade of LED fluorescent lamps uses bolt fastening or interference clip design, and disassembly requires tools such as screwdrivers and pry bars, making the operation process complicated. This makes it more troublesome for maintenance personnel to replace damaged LED strips inside the LED fluorescent lamps. At the same time, since the beam angle of LED fluorescent lamps is mostly preset by the factory (such as 120°, 160° fixed angle), it cannot be adjusted according to the lighting needs of different usage scenarios, resulting in a relatively limited range of applicable scenarios and difficulty in meeting diverse lighting requirements. Utility Model Content

[0010] The present invention is further configured such that vertical plates are fixedly connected to both the left and right sides of the inner wall of the second U-shaped plate, and the surface of the vertical plates is provided with slots.

This eliminates the need for tools when replacing the LED strip, and the replacement process is simple and easy to operate.
[0014] This utility model discloses an LED fluorescent lamp with multiple slots on a vertical plate. By inserting light-shielding plates into different slots, the user can change the angle between the front and rear light-shielding plates.

[0027] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.
[0028] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.
[0029] like Figures 1 to 10 As shown, an LED fluorescent lamp includes a first U-shaped plate 1, a second U-shaped plate 2 fixedly connected to the upper surface of the first U-shaped plate 1, and lamp holders 3 fixedly connected to the inner walls of both the second U-shaped plate 2 and the first U-shaped plate 1. Limiting posts 4 are fitted to the sides of the second U-shaped plate 2, and a transparent lampshade 5 is fixedly connected to the surface of the limiting posts 4. The front and rear sides of the first U-shaped plate 1 and the surface of the second U-shaped plate 2 are both fitted to the inner walls of the transparent lampshade 5. A groove 6 is formed at the bottom of the transparent lampshade 5, and a stop block 7 is fixedly connected to the bottom of the transparent lampshade 5. C-shaped holes 8 are formed on both the front and rear sides of the first U-shaped plate 1. The U-shaped plate 1 has round holes 9 on both the front and back sides. A locking bracket 10 is fixedly connected to the inner wall of the round hole 9. The inner wall of the first U-shaped plate 1, the inner wall of the C-shaped hole 8, and the upper surface of the stop block 7 are all fixedly connected to the surface of the locking bracket 10. A third U-shaped plate 11 is fixedly connected to the inner wall of the first U-shaped plate 1. A positioning hole 12 is opened on the upper surface of the third U-shaped plate 11. An iron sheet 13 is attached to the inner wall of the positioning hole 12. A magnetic block 14 is attached to the bottom of the iron sheet 13. The upper surface of the magnetic block 14 is fixedly connected to the inner wall of the third U-shaped plate 11. An LED light strip 15 is fixedly connected to the upper surface of the iron sheet 13.
[0030] The locking bracket 10 includes a first cylinder 101, a first hollow block 102, a spring 103, a second hollow block 104, a cylinder 105, and a second cylinder 106. The left and right ends of the spring 103 are fixedly connected to the sides of the first hollow block 102 and the second hollow block 104, respectively. The inner wall of the first hollow block 102 is rotatably connected to the surface of the first cylinder 101. The surface of the first cylinder 101 is fixedly connected to the inner wall of the circular hole 9. The inner wall of the second hollow block 104 is fixedly connected to the surface of the cylinder 105. The front and rear ends of the cylinder 105 are both in contact with the inner wall of the first U-shaped plate 1. The inner wall of the cylinder 105 is fixedly connected to the surface of the second cylinder 106. The inner wall of the C-shaped hole 8 and the upper surface of the stop block 7 are both in contact with the surface of the second cylinder 106. The pulling force of the spring 103 on the second hollow block 104 is greater than the sum of the weights of the second hollow block 104, the cylinder 105, and the second cylinder 106.
[0031] The center of LED strip 15 coincides with the center of the third U-shaped plate 11, and the width of LED strip 15 is greater than the width of the third U-shaped plate 11. A PH female terminal 16 is welded to the upper surface of LED strip 15, and a PH male terminal 17 is inserted into the inner wall of PH female terminal 16. PH male terminal 17 is electrically connected to the wiring terminal of lamp holder 3 through a guide. The model of PH female terminal 16 and PH male terminal 17 is PH2.0-2P.
[0032] It should be noted that when the transparent lampshade 5 is placed on the second U-shaped plate 2, the limiting post 4 prevents the transparent lampshade 5 from sliding left and right on the second U-shaped plate 2. The cylinder 105 prevents the second cylinder 106 from moving out of the C-shaped hole 8. The first hollow block 102 can rotate freely on the first cylinder 101. The spring 103 pulls on the second hollow block 104, so that when the second cylinder 106 is located at the end of the C-shaped hole 8, the second cylinder 106 will not move in the C-shaped hole 8 without the action of external force. When the second cylinder 106 contacts the stop block 7, the transparent lampshade 5 can be fixed on the first U-shaped plate 1 through the cooperation of the second cylinder 106, the stop block 7, the second U-shaped plate 2 and the limiting post 4. When the second cylinder 106 is misaligned with the stop block 7, the transparent lampshade 5 can be directly removed from the second U-shaped plate 2.
[0033] The LED strip 15 placed on the third U-shaped plate 11 can be positioned by the cooperation of the positioning block and the iron plate 13. The LED strip 15 can be fixed on the third U-shaped plate 11 by the attraction of the magnetic block 14 to the iron plate 13. At the same time, since the width of the LED strip 15 is greater than the width of the third U-shaped plate 11, it is more convenient for the user to remove the LED strip 15 from the third U-shaped plate 11. When the PH male terminal 17 is inserted into the PH female terminal 16, the lamp head 3 can be connected to the LED strip 15 through the PH male terminal 17 and the PH female terminal 16. When the PH male terminal 17 is pulled out from the PH female terminal 16, the lamp head 3 can be disconnected from the LED strip 15.
[0034] like Figures 1 to 2 As shown, vertical plates 18 are fixedly connected to both the left and right sides of the inner wall of the second U-shaped plate 2. The surface of the vertical plate 18 is provided with a slot 19. The inner wall of the slot 19, the inner wall of the transparent lampshade 5, the side of the limiting post 4, and the inner wall of the second U-shaped plate 2 are all fitted with a light shield 20.
[0035] It should be noted that by setting multiple slots 19 on the vertical plate 18, and by inserting the light shield 20 into the slots 19 at different positions, the user can change the angle between the front and rear light shields 20. At the same time, by changing the angle between the front and rear light shields 20, the illumination range of the LED fluorescent lamp can be adjusted according to different lighting scenarios.
[0036] The working principle of this utility model is as follows: When replacing the LED light strip 15, first pinch both ends of the second cylinder 106, and separate the second cylinder 106 from the stop block 7 by moving the second cylinder 106. At this time, since the second cylinder 106 no longer restricts the upward movement of the transparent lamp cover 5, the transparent lamp cover 5 can be directly removed from the second U-shaped plate 2.
[0037] After the transparent lampshade 5 is removed, since the LED light strip 15 and the third U-shaped plate 11 are fixed by the attraction between the iron sheet 13 and the magnetic block 14, the PH male terminal 17 can be pulled out from the PH female terminal 16, and the maintenance personnel can directly remove the damaged LED light strip 15 from the third U-shaped plate 11.
[0038] Then, place the new LED light strip 15 on the third U-shaped plate 11 and insert the iron piece 13 into the positioning hole 12. At this time, the LED light strip 15 can be fixed on the third U-shaped plate 11 by the attraction of the magnetic block 14 to the iron piece 13. Then, insert the PH male terminal 17 into the PH female terminal 16. The lamp head 3 and the LED light strip 15 can be connected through the PH male terminal 17 and the PH female terminal 16.
[0039] Next, place the transparent lampshade 5 on the second U-shaped plate 2 and make the side of the limiting post 4 fit against the side of the second U-shaped plate 2. At this time, the limiting post 4 can prevent the transparent lampshade 5 from sliding left and right on the second U-shaped plate 2. Then, pinch both ends of the second cylinder 106 and move the second cylinder 106 to contact the stop block 7. At this time, since the second cylinder 106 is located at the end of the C-shaped hole 8, and the spring 103 pulls on the second hollow block 104, when the second cylinder 106 is located at the end of the C-shaped hole 8, the second cylinder 106 will not move in the C-shaped hole 8 without the action of external force. Thus, through the cooperation of the second cylinder 106, the stop block 7, the second U-shaped plate 2 and the limiting post 4, the transparent lampshade 5 can be fixed on the first U-shaped plate 1.
[0040] When it is necessary to adjust the illumination range of the LED fluorescent lamp, first pinch both ends of the second cylinder 106, and then move the second cylinder 106 to separate it from the stop block 7. At this time, since the second cylinder 106 no longer restricts the upward movement of the transparent lamp cover 5, the transparent lamp cover 5 can be directly removed from the second U-shaped plate 2.
[0041] After the transparent lampshade 5 is removed, the light-shielding plate 20 is pulled out from the original slot 19 and inserted into the slot 19 at the appropriate position, so that the included angle between the two light-shielding plates 20 changes, thereby changing the illumination range of the LED fluorescent lamp.
[0042] After adjusting the angle between the two light-shielding plates 20 to a suitable size, place the transparent lampshade 5 on the second U-shaped plate 2 and make the side of the limiting post 4 fit against the side of the second U-shaped plate 2. At this time, the limiting post 4 can prevent the transparent lampshade 5 from sliding left and right on the second U-shaped plate 2. Then, pinch both ends of the second cylinder 106 and move the second cylinder 106 to contact the stop block 7. At this time, since the second cylinder 106 is located at the end of the C-shaped hole 8, and the spring 103 pulls on the second hollow block 104, when the second cylinder 106 is located at the end of the C-shaped hole 8, the second cylinder 106 will not move in the C-shaped hole 8 without the action of external force. Thus, through the cooperation of the second cylinder 106, the stop block 7, the second U-shaped plate 2 and the limiting post 4, the transparent lampshade 5 can be fixed on the first U-shaped plate 1.
[0043] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model, unless otherwise specified or limited, shall be implemented using conventional methods in the field.
