For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0027] like Figure 1-5 As shown, this utility model discloses a lamp tube with a three-layer optical mask, including a lamp holder 10, and a light-emitting element 20 and a lamp body 30 disposed on the lamp holder 10. The light-emitting element 20 and the lamp body 30 are both arranged in a long strip shape. The light-emitting element 20 is an LED lamp board, and the lamp holder 10 is formed by heat dissipation aluminum profile.

[0028] The lamp body 30 has an inner cover 31, an outer cover 32, and an anti-glare film 33. The inner cover 31 and the outer cover 32 are co-extruded in two colors. The light-emitting element 20 is located in the inner cover 31. The outer cover 32 surrounds the outer periphery of the inner cover 31. A receiving cavity 34 is formed between the inner cover 31 and the outer cover 32. The anti-glare film 33 is located in the receiving cavity 34 and surrounds the outer periphery of the inner cover 31.

[0029] The inner cover 31 is a frosted diffuser that can scatter light, the outer cover 32 is a transparent cover, and the anti-glare film 33 has a textured decorative layer with a thickness of 0.1mm-0.5mm.

[0030] The inner cover 31 has a first arc-shaped portion 311, and the outer cover 32 has a second arc-shaped portion 321. The first arc-shaped portion 311 and the second arc-shaped portion 321 are spaced apart to form the accommodating cavity 34. The anti-glare film 33 is an arc-shaped anti-glare film 33. By setting the first arc-shaped portion 311, the second arc-shaped portion 321 and the arc-shaped anti-glare film 33, the arc-shaped structure has the advantages of a large light-emitting angle, high luminous efficiency and reduced glare, resulting in good light-emitting effect and visual comfort of the lamp.

[0031] The first arc-shaped portion 311 has a first snap-fit ​​member 35 between its two sides and the edge of the adjacent second arc-shaped portion 321. The lamp holder 10 has a second snap-fit ​​member 11 that corresponds to the first snap-fit ​​member 35. The cooperation between the first snap-fit ​​member 35 and the second snap-fit ​​member 11 allows the lamp body 30 to snap into the lamp holder 10. By setting the first snap-fit ​​member 35 and the second snap-fit ​​member 11, the lamp body 30 and the lamp holder 10 can be snapped into place, making it easy to install and disassemble.

[0032] The first snap-fit ​​member 35 has an extension 351 and a bend 352 connected to each other. The extension 351 is connected to the first arc-shaped portion 311, and the end of the extension 351 away from the first arc-shaped portion 311 has a protrusion 353. One end of the bend 352 is connected to the second arc-shaped portion 321. The bend 352, the extension 351 and the protrusion 353 form a snap-fit ​​groove 354. The second snap-fit ​​member 11 has a snap-fit ​​block 111. During assembly, the snap-fit ​​block 111 is snapped into the snap-fit ​​groove 354.

[0033] The two extensions 351 are arranged in a figure-eight shape, and a clearance groove is formed between the two extensions 351. The lamp holder 10 is provided with a T-shaped member 12 that extends into the clearance groove. The light-emitting element 20 is installed on the plate portion 121 at the lower end of the T-shaped member 12. By providing a T-shaped member 12 that extends into the clearance groove on the lamp holder 10 and installing the light-emitting element 20 on the plate portion 121 at the lower end of the T-shaped member 12, the assembly structure of the lamp holder 10, the light-emitting element 20 and the lamp body 30 is compact and occupies little space.

[0034] A limiting groove 36 is provided between the edge of the first snap-fit ​​member 35 and the edge of the second arc-shaped part 321. The limiting groove 36 is connected to the receiving cavity 34. During assembly, the two sides of the arc-shaped anti-glare film 33 are respectively inserted into the corresponding limiting groove 36, and the outer circumferential wall surface of the arc-shaped anti-glare film 33 is in contact with the inner circumferential wall surface of the outer cover 32. By setting the limiting groove 36, the two sides of the arc-shaped anti-glare film 33 are limited, avoiding the positional displacement of the arc-shaped anti-glare film 33, making the outer circumferential wall surface of the arc-shaped anti-glare film 33 more stably in contact with the inner circumferential wall surface of the outer cover 32, and preventing the arc-shaped anti-glare film 33 from deforming.

[0035] The central axis of the first arc-shaped portion 311, the central axis of the second arc-shaped portion 321, and the central axis of the arc-shaped anti-glare film 33 are coaxially arranged, and the distance between the first arc-shaped portion 311 and the arc-shaped anti-glare film 33 is 5mm-10mm. By adopting a distance of 5mm-10mm between the first arc-shaped portion 311 and the arc-shaped anti-glare film 33, the light emitted by the light-emitting element 20 has a large scattering space after passing through the first arc-shaped portion 311, so that the light is evenly scattered onto the arc-shaped anti-glare film 33.

[0036] The textured decorative layer has at least one of wave pattern, polygonal pattern and frosted texture.

[0037] The accommodating cavity 34 is open at least one end along the length of the outer cover 32, forming an opening 341. The opening 341 allows the anti-glare film 33 to be inserted into the accommodating cavity 34. An end cap 40 is provided at the opening 341, and the end cap 40 is detachably connected to the lamp holder 10. For example, both ends of the accommodating cavity 34 along the length of the outer cover 32 are open to form openings 341. By providing an opening 341 at one end of the accommodating cavity 34, it is convenient to insert or remove the anti-glare film 33 from the accommodating cavity 34, thereby facilitating the replacement of anti-glare films 33 with different textured decorative layers and achieving different visual effects.

[0038] In summary, this utility model provides a lamp body 30 with a three-layer optical mask consisting of an inner cover 31, an outer cover 32, and an anti-glare film 33. The light-emitting element 20 is located in the inner cover 31, the outer cover 32 surrounds the outer periphery of the inner cover 31, and the anti-glare film 33 is located in the accommodating cavity 34 formed between the inner cover 31 and the outer cover 32. The anti-glare film 33 surrounds the outer periphery of the inner cover 31. The inner cover 31 is a frosted diffuser, the outer cover 32 is a transparent cover, and the anti-glare film 33 has a textured decorative layer. In use, the light emitted by the light-emitting element 20 passes through the frosted diffuser and is evenly scattered onto the textured decorative layer on the anti-glare film 33. Finally, the light effect of the textured decorative layer is displayed through the transparent cover, thereby avoiding the exposure of point light sources, making the light uniform and soft, not dazzling, reducing glare, and lowering UGR.
