[0026] like Figures 1-6 As shown, this utility model provides an all-plastic LED tube with a rotatable lamp head, characterized in that it includes: a tube body 10, a lamp plate 11 inside the tube body 10, and end cap assemblies 12 at both ends of the tube body 10. The end cap assembly 12 includes: an end cap base 121, the first end of which is inserted into the tube body 10 and connected to the tube body 10, and an outer cover 124 movably connected to the second end of the end cap base 121. The outer cover 124 can rotate relative to the end cap base 121. A limiting member 14 is also movably provided between the outer cover 124 and the end cap base 121. The limiting member 14 can slide up and down between the outer cover 124 and the end cap base 121. The sliding of the limiting member 14 can lock or unlock the rotation of the outer cover 124. The outer cover 124 is also provided with a power terminal 128, which is electrically connected to the lamp plate 11.

[0027] Specifically, each end of the lamp tube body 10 is provided with a plug assembly 12, and at least one end of the plug assembly 12 has a plug base 121. The first end of the plug base 121 is inserted into the lamp tube body 10 and connected to the lamp tube body 10. An outer cover 124 is movably connected to the second end of the plug base 121. The outer cover 124 can rotate relative to the plug base 121. A power terminal 128 is also provided at the end of the outer cover 124 away from the plug base 121. The power terminal 128 is connected to an external lamp tube socket and connected to the power supply. In the actual installation process, the outer cover 124 is inserted into the lamp tube socket through the power terminal 128. At this time, the outer cover 124 is fixed, while the plug base 121 and the lamp tube body are connected. 10 is movable and can be movably connected to the outer cover 124 via the end cap base 121, causing the lamp tube body 10 to rotate, thereby adjusting the illumination angle and range of the lamp tube body 10. To facilitate fixing the illumination angle of the lamp tube body 10, a limiting member 14 is also movably provided between the end cap base 121 and the outer cover 124. The limiting member 14 is located on the side wall of the end cap base 121 and the outer cover 124, and the limiting member 14 can slide between the end cap base 121 and the outer cover 124. When the limiting member 14 slides, it can release or restrict the mutual rotation between the outer cover 124 and the end cap base 121. Under this structure, the end cap assembly can be made to be less than 16mm in length, so as not to block the light output.

[0028] Furthermore, one side of the limiting member 14 is located inside the outer cover 124, and the bottom end of the limiting member 14 located inside the outer cover 124 is provided with a tenon 15. The plug base 121 is provided with a plurality of grooves 126 that are adapted to the tenon 15. The top end of the limiting member 14 located inside the outer cover 124 is provided with a spring (not shown in the figure), and the spring slides downward against the limiting member 14.

[0029] Specifically, the limiting member 14 is located inside the outer cover 124. A tenon 15 is provided at the bottom of one side of the limiting member 14 inside the outer cover 124. Simultaneously, several grooves 126 are provided on the top surface of the plug base 121. These grooves 126 are semi-circularly distributed and fit with the tenon 15. When the limiting member 14 slides between the plug base 121 and the outer cover 124, it causes the tenon 15 to insert into or disengage from the groove 126, thereby releasing or restricting the movement of the plug base 121 and the outer cover. To prevent the limiting member 14 from becoming loose during rotation between 124, a spring is installed on the end of the limiting member 14 away from the tenon 15. One end of the spring contacts the outer cover 124, and the other end contacts the top of the limiting member 14 on one side of the outer cover 124. Through the setting of the spring, the limiting member 14 is pressed down by the force of the spring, so that the tenon 15 is inserted into the groove 126. When rotation is required, the limiting member 14 can be moved to compress the spring and drive the tenon 15 out of the groove 126.

[0030] Furthermore, a retaining ring 123 is provided in the middle of the plug base 121, and a plurality of connecting hook blocks 125 are provided at intervals in the middle of the outer cover 124, the connecting hook blocks 125 being adapted to the retaining ring 123;

[0031] Specifically, to simplify the connection between the plug base 121 and the outer cover 124, a retaining ring 123 is provided in the middle of the plug base 121. The top of the retaining ring 123 extends horizontally towards the center, making the retaining ring 123 appear as a hook. At the same time, a connecting hook block 125 is provided in the middle of the outer cover 124. Several connecting hook blocks 125 are provided and spaced apart. Since the adjacent connecting hook blocks 125 are discontinuous, the connecting hook blocks 125 can have a certain bending ability due to the toughness of their own material. Therefore, when the outer cover 124 is connected to the plug base 121, the connecting hook block 125 will be inserted into the retaining ring 123 and the end will hook with the retaining ring 123, thereby realizing the quick installation of the outer cover 124 and the plug base 121.

[0032] Furthermore, the first end of the plug base 121 is provided with a protruding locking block 122, and the end of the lamp tube body 10 is provided with a locking hole 13 that is adapted to the locking block 122.

[0033] Specifically, to facilitate the installation between the plug base 121 and the lamp tube body 10, a protruding locking block 122 is provided on the outer side of the first end of the plug base 121, and a locking hole 13 adapted to the locking block 122 is provided at the end of the lamp tube body. When the first end of the plug base 121 is inserted into the lamp tube body 10, the locking block 122 is embedded in the locking hole 13, thereby fixing the plug base 121 and the lamp tube body 10. In order to avoid the locking block 122 from affecting the insertion of the plug base 121, the end of the locking block 122 corresponding to the insertion direction is provided with a chamfer, thereby preventing the locking block 122 from restricting the insertion of the plug base 121.

[0034] Furthermore, a through hole 127 is provided at the position corresponding to the connecting hook block 125 on the outer cover 124;

[0035] Specifically, to facilitate the disassembly of the plug base 121 and the outer cover 124, a through hole 127 is provided at the position corresponding to the connecting hook block 125 on the outer cover 124. The area of ​​the through hole 127 covers at least one connecting hook block 125. When the area covers one connecting hook block 125, the number of through holes 127 corresponds to the number of connecting hook blocks 125. When disassembly is required, an external structural component can be inserted into the outer cover 124 through the through hole 127 and the connecting hook block 125 can be squeezed to release the engagement between it and the retaining ring 123. At this time, the outer cover 124 can be removed from the plug base 121.

[0036] Furthermore, the lamp tube body 10 includes a light-transmitting surface 16 and an opaque surface 17. The area of ​​the light-transmitting surface 16 is larger than the area of ​​the opaque surface 17. The lamp tube body 10 is also provided with a partition 18. The side of the partition 18 facing the light-transmitting surface 16 is provided with a slot 19. The lamp plate 11 is fixed to the partition 18 through the slot 19.

[0037] Specifically, the lamp body 10 is made of dual-color plastic, with a light-transmitting surface 16 and an opaque surface 17. The light-transmitting surface 16 is made of high-transmittance PC (polycarbonate), and the opaque surface 17 is made of opaque PC, which helps to reduce weight. Inside the lamp body 10, there is also a plastic partition 18, which divides the interior of the lamp body 10 into two cavities. The side of the partition 18 facing the light-transmitting surface 16 has a slot 19, through which the lamp board 11 is fixed to the partition 18. The other cavity can be used to install the driver power supply. The driver power supply is separated from the lamp board 11 by the plastic partition 18. By utilizing the insulating properties of plastic, the additional insulation material is reduced, thus lowering costs. At the same time, due to the reduction of insulation material, the internal space of the lamp body 10 is more spacious, and the driver power supply can be better dissipated when placed inside. Furthermore, since both the lamp body and the partition 18 are insulating materials, the risk of leakage is effectively avoided, ensuring user safety.

[0038] It should be noted that, except for the electrical terminal 128, all other components of the plug assembly 12 are made of plastic, which reduces weight and cost.

[0039] In summary, by connecting the plug base 121 and the outer cover 124 movably and cooperating with the limiting component 14, the lamp tube body 10 can be rotated, the illumination angle of the lamp tube body 10 can be adjusted to meet the lighting needs of different angles, and the practicality of the lamp can be improved. In addition, both the lamp tube body 10 and the plug assembly 12 are made of plastic, which reduces weight and material costs. Furthermore, the plastic material can avoid the risk of electric leakage and ensure user safety.

[0040] This invention is not limited to the description in the specification and embodiments. Therefore, other advantages and modifications can be readily realized by those skilled in the art. Thus, without departing from the spirit and scope of the general concept as defined by the claims and their equivalents, this invention is not limited to the specific details, representative devices and illustrated examples shown and described herein.
