[0027] In the description of the present invention, unless otherwise clearly defined, terms such as setting, installing, connecting, etc. should be understood in a broad sense, and technicians in the relevant technical field can reasonably determine the specific meanings of the above terms in the present invention based on the specific content of the technical solution.

[0028] Reference Figures 1 to 4 The lamp tube of the embodiment of the utility model includes a base 100 and a lampshade 200. A lamp strip 110 is installed on the upper side of the base 100, and lamp beads 120 are fixed on the lamp strip 110. Card slots 130 are provided on both sides of the base 100 along the extension direction of the base 100; the lampshade 200 is installed on the upper side of the base 100, and card blocks 210 are provided on both sides of the lampshade 200. The card blocks 210 are card-connected with the card slots 130. The lampshade 200 is transparent and covers the top of the lamp beads 120.

[0029] The light belt 110 on the base 100 is used to drive the lamp beads 120, and the wires (not shown in the figure) connected to the light belt 110 are used to connect to the external power supply to power the lamp beads 120, so that the lamp beads 120 emit light. Among them, using the light belt 110 to power and drive the lamp beads 120 belongs to the conventional means in the field, which will not be described in detail here. Specifically, when installing the lamp tube, the card block 210 is directly inserted into the card slots 130 on both sides, and the entire transparent lampshade 200 covers The lamp bead 120 constructs the shape of a lamp tube and replaces the lamp tube structure in the prior art. During daily maintenance, the lampshade 200 can be directly disassembled and the broken lamp bead 120 on the lamp strip 110 can be replaced, or the entire lamp strip 110 can be replaced. After the replacement is completed, it is only necessary to re-engage the slot 130 and the block 210. In summary, the snap-fit ​​cooperation between the slot 130 and the block 210 can facilitate the replacement of the lamp bead 120 on the base 100 and facilitate maintenance.

[0030] In some embodiments, in order to facilitate installation and disassembly, the card slot 130 extends from one end of the base 100 to the other end of the base 100, and the card block 210 and the card slot 130 are slidably matched, so that the card block 210 can and can only move along the card slot 130. During the assembly process, the card block 210 is inserted from one end of the base 100, so that the card block 210 is embedded in the card slot 130, and the card block 210 slides along the card slot 130. After the positions of the base 100 and the lampshade 200 match, the installation is completed. When disassembling, the lampshade 200 can also be slid out from either end, simplifying the steps of disassembly and assembly.

[0031] In order to improve the integrity of the entire lamp tube, preferably, the end of the base 100 is detachably connected with a plug 300, and the plug 300 is provided with a first accommodating cavity 310 and a second accommodating cavity 320. The base 100 is embedded in the first accommodating cavity 310, and the lampshade 200 is embedded in the second accommodating cavity 320. The plug 300 is used to block both sides of the base 100 to prevent the base 100 and the lampshade 200 from sliding relative to each other and separating, and the integrity of the lamp tube shape can be improved. At the same time, the first accommodating cavity 310 and the second accommodating cavity 320 are used to match the shapes of the base 100 and the lampshade 200, respectively, so as to facilitate their installation and removal.

[0032] Specifically, the bottom surface of the first accommodating cavity 310 is provided with an elastic clamping member 311, and the bottom surface of the lower side of the base 100 is provided with a clamping groove 140, and the clamping member 311 is embedded in the clamping groove 140 and clamped with the clamping groove 140. The base 100 can be fixed during installation by utilizing the detachable connection between the elastic clamping member 311 and the clamping groove 140.

[0033] It should be mentioned that guide grooves 312 are provided on both sides of the first accommodating cavity 310, and guide protrusions 160 are provided on both sides of the base 100, and the guide protrusions 160 can be slidably embedded in the guide grooves 312. In actual installation, the block 210 of the lampshade 200 is first slid into the card groove 130 to complete the connection between the lampshade 200 and the base 100, and then the guide protrusion 160 is embedded in the guide groove 312, so that the guide protrusion 160 slides along the guide groove 312, and then the plug 300 is sleeved on the ends of the lampshade 200 and the base 100 to complete the installation, thereby improving the convenience of installation.

[0034] In some embodiments, the lampshade 200 is arc-shaped in the cross section of the lamp tube. The arc-shaped cross section of the lampshade 200 can better diffuse the light emitted by the lamp beads 120. At the same time, the arc of the lampshade 200 is greater than 180° and less than 270°, which effectively improves the overall light effect of the light tube and expands the irradiation range. In order to reduce the glare effect, the surface of the lampshade 200 is frosted.

[0035] In some embodiments, in order to reduce costs, the base 100 is provided with an inner cavity 150, and the inner cavity 150 runs from one end of the base 100 to the other end of the base 100. The entire base 100 can be integrally formed by a sheet metal process, thereby reducing costs and improving production efficiency.

[0036] The embodiments of the present invention are described in detail above in conjunction with the accompanying drawings, but the present invention is not limited to the above embodiments, and various changes can be made within the knowledge scope of ordinary technicians in the relevant technical field without departing from the purpose of the present invention.
