[0029] Please refer to Figure 1 and Figure 2The application discloses a 360-degree light-emitting lamp tube which comprises a lamp shell 1, a light source module 2 and an end cover 3. The main body structure of the lamp shell 1 is a long-strip cylinder with two open ends, and the lamp shell 1 comprises an outer shell 11, an inner tube 12 and a connecting part 13. The outer shell 11 and the inner tube 12 are both long-strip cylinder structures, and the lengths of the two are the same and the two ends are aligned; the inner diameter of the outer shell 11 is larger than the outer diameter of the inner tube 12. The inner tube 12 is arranged in the outer shell 11 and connected with the outer shell 11 through the connecting part 13. The light source module 2 is provided with N (N>=2 and N should be a positive integer) light source modules. The N light source modules 2 are uniformly arranged around the central axis of the inner tube 12, and the N light source modules 2 are all located between the inner tube 12 and the outer shell 11. The end cover 3 is provided with two end covers 3 which are respectively arranged at the two open ends of the lamp shell 1. It is easy to understand that the outer shell 11 is made of transparent or semi-transparent material so that the light emitted by the light source module 2 can pass through the outer shell 11 and be emitted outward to achieve the purpose of illumination.

[0030] Most of the existing lamp tubes can only realize 180-degree or 270-degree light-emitting, and even some lamp tubes can realize 360-degree light-emitting, but the internal structures of the lamp tubes are relatively complex. According to the technical scheme, the lamp shell 1 structure composed of the outer shell 11, the inner tube 12 and the connecting part 13 is arranged, and two or more light source modules 2 are arranged between the outer shell 11 and the inner tube 12, so that 360-degree light-emitting is realized and the internal structure of the lamp tube is simpler.

[0031] When N=2, the two light source modules 2 are symmetrically arranged relative to the central axis of the inner tube 12, and since the light emitted by the light source has divergence, 360-degree light-emitting of the lamp tube can be realized.

[0032] In an embodiment, the number of the light source modules 2 is three, that is, N=3. The three light source modules 2 are also uniformly arranged around the central axis of the inner tube 12. By arranging three light source modules 2, the light emitted by the three light source modules 2 can cover a wider range, and the 360-degree light-emitting effect is better.

[0033] In an embodiment, please refer to Figure 2 and Figure 3 The number of the light source modules 2 is four, that is, N=4. The four light source modules 2 are also uniformly arranged around the central axis of the inner tube 12. The four light source modules 2 can further improve the 360-degree light-emitting effect.

[0034] Further, please refer to Figure 3 and Figure 4The plurality of connecting portions 13 are evenly arranged around the central axis of the inner tube 12 to divide the area between the inner tube 12 and the outer shell 11 into a plurality of cavities 14, and at least one light source module 2 is arranged in each cavity 14. The connecting portion 13 is a thin-walled structure connecting the inner wall of the outer shell 11 and the outer wall of the inner tube 12, and the length of the connecting portion 13 is consistent with the length of the outer shell 11 and the inner tube 12. The connecting portion 13 divides the area between the outer shell 11 and the inner tube 12 to form independent cavities 14. In this embodiment, three connecting portions 13 are evenly distributed around the central axis of the inner tube 12 to divide the area between the outer shell 11 and the inner tube 12 into four cavities 14, and one light source module 2 is arranged in each cavity 14. Of course, in other embodiments, two, three or other numbers of light source modules 2 can also be arranged in each cavity 14. The structure of the lamp shell 1 is thus arranged, which not only improves the structural stability, but also facilitates the arrangement of the light source module 2 in each cavity 14.

[0035] Referring to Figure 3 The light source module 2 is specifically arranged on the outer side wall of the inner tube 12, and the direction of light emission is towards the outer shell 11, and the light passes through the outer shell 11 and is emitted outward. The light source module 2 can be fixed on the outer side wall of the inner tube 12 by pasting or other means, which is simple in structure and convenient to assemble. Of course, in other embodiments, the light source module 2 can also be fixed between the outer shell 11 and the inner tube 12 by abutting against the two adjacent connecting portions 13 on both sides.

[0036] The outer shell 11, the inner tube 12 and the connecting portion 13 are of an integrated structure, that is, they are integrally formed to form the lamp shell 1. The lamp shell 1 is integrally formed, so it is stable in structure, convenient to produce, and also convenient to assemble into a lamp tube. The lamp shell 1 is specifically made of plastic material to facilitate integrally forming.

[0037] The lamp shell 1 and the inner tube 12 are both of a cylindrical structure, and the central axes of the two are collinear. The structure is reasonable and convenient to integrally form.

[0038] Referring to Figure 5 The light source module 2 includes a base material 21 and a light-emitting surface material 22 arranged on the base material 21. The base material 21 is a long strip-shaped plate structure, and the light-emitting surface material 22 is a long strip-shaped plate structure with a light-emitting source. The light-emitting surface material 22 is arranged on the base material 21, and one end of the base material 21 away from the light-emitting surface material 22 is fixed on the outer side wall of the inner tube 12. The light-emitting surface material 22 is a continuous light-emitting surface, and compared with the existing light source group composed of a plurality of LED point light sources arranged at intervals, the light source module 2 has light-emitting continuity without interruption, and the light-emitting effect is better.

[0039] The inner tube 12 is of a cylindrical structure, so the outer side wall thereof in contact with the light source module 2 is an arc surface. In order to better fix the light source module 2 on the outer side wall of the inner tube 12, the base material 21 can be made of a flexible material.

[0040] Please refer to Figure 2 and Figure 3 The lamp tube further comprises a driving power supply 4 electrically connected with the light source module 2 and the electrode 31 on the end cover 3. The electrode 31 on the end cover 3 is used for connecting with commercial power. The light source module 2 is arranged between the inner tube 12 and the shell 11, and the inner tube 12 is a cylindrical structure with hollow interior and open ends, so that the area inside the inner tube 12 can be better used for arranging the driving power supply 4.

[0041] The above merely describes the preferred embodiments of the present application, and is not intended to limit the patent scope of the present application. Any equivalent structural transformation made according to the contents of the present application specification and drawings, or direct / indirect application in other related technical fields under the inventive concept of the present application shall be included in the patent protection scope of the present application.
