Description

Technical Field

[0001] This utility model relates to the field of lamp technology, specifically to an LED lamp tube with a rotatable lamp head. Background Technology

[0002] LED fluorescent lamps have been widely used in the market due to their many significant advantages, such as long lifespan, small size, and energy saving. They are gradually replacing traditional incandescent lamps. Currently, common LED tubes generally have a light-emitting surface in a specific direction. However, in some special installation positions, the light-emitting surface of the tube must be adjusted according to the actual angle requirements. If it is not adjusted, the tube will not be able to achieve the expected lighting range and brightness requirements.

[0003] However, most existing light tubes do not have angle adjustment function. Even if there are a few adjustable light tubes, the adjustment requires first removing the light tube from the light tube bracket, then rotating the lamp heads at both ends of the light tube in turn until the light-emitting surface of the light tube faces the required angle, and finally reinstalling the light tube back into the light tube bracket. This adjustment method is not only difficult to be precise, but also often requires multiple adjustments, making the operation extremely inconvenient. Utility Model Content

[0004] To solve the above-mentioned technical problems, an LED tube with a rotatable lamp head is provided. This technical solution solves the problem mentioned in the background art that it is difficult to flexibly adjust according to actual angle requirements.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] An LED tube with a rotatable lamp head includes: a tube body and a limiting block. The limiting block is installed inside the tube body near the bottom end. A lamp cover is inserted into the tube body at the limiting block. Positioning grooves are formed on the outer surfaces of both the tube body and the lamp cover near the top end. A limiting component is provided inside the lamp cover at the positioning groove. A fixing block is inserted into the positioning groove.

An inclined block is fixedly installed on one side of the inner surface of the first connecting ring opposite the fixing block. A second connecting ring abuts against one side of the outer surface of the first connecting ring.

[0007] Preferably, a limiting strip is provided on one side of the outer surface of the second connecting ring, and a movable insert is slidably installed on one side of the outer surface of the limiting strip. A magnetic sheet is fixedly installed on the opposite side of the outer surface of the inclined block and the movable insert, and the two sets of magnetic sheets are set to repel each other. One end of the outer surface of the movable insert penetrates through the outer surface of the second connecting ring, the lamp cover and the tube body and is engaged in the positioning groove.

[0008] Preferably, a lamp is inserted into the inside of the lampshade, and the top of the outer surface of the lamp abuts against a limiting component. A rotating base is provided at the bottom of the outer surface of the lamp, and bosses are fixedly installed on both sides of the outer surface of the rotating base, with the top of the outer surface of the bosses abutting against a limiting block.

[0009] Preferably, a limiting ring is fixedly installed on the inner side of the bottom end of the outer surface of the rotating base, a buckle is installed on the bottom end of the outer surface of the rotating base, and a rotating socket is inserted into the shaft surface of the limiting ring.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] This solution proposes an LED tube with a rotatable lamp head. Through the cooperation of components such as positioning grooves, fixed plugs, and movable plugs, as well as the repulsive effect of magnetic sheets, precise positioning can be achieved when adjusting the angle. The movable plugs can engage with different positioning grooves to provide multiple fixed angle options, meeting the precise requirements of the light emission angle of the lamp tube in different scenarios. Compared with traditional adjustment methods that are difficult to achieve precise positioning, this solution can better achieve the required lighting range and brightness. The lamp, lampshade, and tube body are connected by various structures such as limiting components, limiting blocks, bosses, and limiting rings. During angle adjustment and normal use, the connection between the components can be ensured to be tight, and there will be no unstable conditions such as shaking or displacement. This ensures that the lamp tube works stably at different angles and extends the service life of the lamp tube. Attached Figure Description

[0021] The following description is intended to disclose the present invention so that those skilled in the art can implement it. The preferred embodiments described below are merely examples, and other obvious variations will occur to those skilled in the art.

[0022] Reference Figure 1-4As shown, an LED tube with a rotatable lamp head includes: a tube body 1 and a limiting block 12. The limiting block 12 is installed inside the tube body 1 near the bottom. The tube body 1 and the lamp cover 5 are connected by a positioning groove 4 and related components to achieve angle adjustment. When it is necessary to adjust the light emission angle of the tube, the fixed plug 73 is inserted into the positioning groove 4. The bottom end of the fixed plug 73 is connected to the first connecting ring 71, which abuts against the second connecting ring 72. The limiting strip 77 on the second connecting ring 72 allows the movable plug 75 to slide. Since the magnetic pieces 76 on the opposite sides of the inclined block 74 and the movable plug 75 repel each other, when an external force is applied to the lamp cover 5 to make it rotate relative to the tube body 1, the movable plug 75 will be locked at different positions in the positioning groove 4 under the repulsive force of the magnetic pieces 76 and the constraint of the limiting strip 77, thereby fixing the lamp cover 5 and the tube body 1. The relative angle between the lamps allows for initial angle adjustment and positioning. The lamp 6 is inserted into the lampshade 5, with its top end limited by the limiting component 7 to ensure the lamp 6's stable position within the lampshade 5. The rotating base 8 connected to the bottom of the lamp 6 engages with the limiting block 12 inside the tube body 1 via the boss 14. When the lamp 6 rotates with the lampshade 5, the rotating base 8 also rotates. The limiting ring 15 on the inner side of the bottom end of the rotating base 8 is inserted into the rotating socket 9. The locking block 16 on the rotating socket 9 engages with the structure of the rotating base 8, and the locking piece 13 at the bottom end of the rotating base 8 engages with the locking groove of the rotating socket 9, allowing the rotating base 8 to drive the rotating socket 9 to rotate together. The positioning piece 10 engages in the locking groove 17 of the rotating socket 9, and the top end of the positioning piece 10 is connected to the rotating fixing piece 11 for rotational fixing. Part 11 is fitted with a rotating ring 3, which in turn abuts against the bottom shaft surface of the tube body 1. The bottom end of the rotating ring 3 is fitted with a rotating head cover 2. In this way, the rotation of the lamp 6 is transmitted through a series of connecting structures, ultimately achieving the coordinated rotation of components such as the rotating head cover 2, thereby adjusting the light output direction of the lamp tube as a whole. Inside the tube body 1, a lampshade 5 is inserted at the limiting block 12. Positioning grooves 4 are provided on the outer surfaces of both the tube body 1 and the lampshade 5 near the top. A limiting component 7 is provided inside the lampshade 5 at the positioning groove 4. A fixing block 73 is inserted inside the positioning groove 4. A first connecting ring 71 is fixedly installed at the bottom of the outer surface of the fixing block 73. An inclined block 74 is fixedly installed on one side of the inner surface of the first connecting ring 71, directly opposite the fixing block 73. A second connecting block 74 is abutted on one side of the outer surface of the first connecting ring 71. The second connecting ring 72 has a limit strip 77 on one side of its outer surface. A movable insert 75 is slidably installed on one side of the outer surface of the limit strip 77. A magnetic sheet 76 is fixedly installed on the opposite side of the outer surface of the inclined block 74 and the movable insert 75, and the two sets of magnetic sheets 76 are set to repel each other. One end of the outer surface of the movable insert 75 passes through the outer surface of the second connecting ring 72, the lamp cover 5, and the tube body 1 and is engaged with the positioning groove 4. A lamp 6 is inserted into the inside of the lamp cover 5, and the top of the outer surface of the lamp 6 abuts against the limit component 7. A rotating base 8 is provided at the bottom of the outer surface of the lamp 6. Bosses 14 are fixedly installed on both sides of the outer surface of the rotating base 8, and the top of the outer surface of the bosses 14 abuts against the limit block 12. A limit ring 15 is fixedly installed on the inner side of the bottom of the outer surface of the rotating base 8.A latching element 13 is installed at the bottom of the outer surface of the rotating base 8. A rotating socket 9 is inserted into the shaft surface of the limiting ring 15. Several sets of latching blocks 16 are fixedly installed on the inner side of the shaft surface of the rotating socket 9. A latching groove is opened at the bottom of the outer surface of the rotating socket 9, and one end of the outer surface of the latching element 13 is latched into the latching groove of the rotating socket 9. A positioning element 10 is latched onto the outer surface of the internal slot 17 of the rotating socket 9. A rotating fixing element 11 is fixedly installed at the top of the outer surface of the positioning element 10. A rotating ring 3 is sleeved on the shaft surface of the rotating fixing element 11, and the shaft surface of the rotating ring 3 abuts against the bottom end of the shaft surface of the tube body 1. A rotating head cover 2 is sleeved at the bottom end of the outer surface of the rotating ring 3.

[0023] Working principle and implementation method: When it is necessary to adjust the light output angle of the lamp tube, the operator applies an appropriate external force to make the rotating ring 3 rotate relative to the tube body 1. During the rotation, the rotating ring 3 drives the rotating fixing part 11 sleeved on its shaft surface to rotate together. Since the top of the rotating fixing part 11 is connected to the positioning part 10, the positioning part 10 is engaged in the slot 17 of the rotating socket 9, thereby driving the rotating socket 9 to rotate. The locking block 16 on the inner side of the shaft surface of the rotating socket 9 interacts with the structure of the rotating base 8. In addition, the locking part 13 at the bottom of the rotating base 8 is tightly engaged with the locking slot of the rotating socket 9, causing the rotating base 8 to rotate accordingly. The rotating base 8 cooperates with the limiting block 12 in the tube body 1 through the boss 14. The bottom of the lamp 6 is connected to the rotating base 8, and the top is limited by the limiting component 7 in the lamp cover 5, so that the lamp 6 is stable in position in the lamp cover 5 and rotates with the rotation of the rotating base 8.

Those skilled in the art should understand that this utility model is not limited to the above embodiments.
