[0062] In one embodiment, a plugging part 511 protrudes from the first cover body 51. A plugging groove 521 is arranged on the end face of the second cover body 52 close to the first cover body 51. The first cover body 51 and the second cover body 52 are detachably assembled through the plugging fit between the plugging part 511 and the plugging groove 521. With such a setting, the decorative cover 5 is not only convenient to disassemble and assemble, but also can reduce the manufacturing difficulty, thereby reducing the manufacturing cost.

[0063] In another embodiment, the plugging part 511 can also be arranged on the second cover body 52. Correspondingly, the plugging groove 521 is arranged on the first cover body 51. Alternatively, both the first cover body 51 and the second cover body 52 are provided with the plugging part 511 and the plugging groove 521, and the plugging part 511 and the plugging groove 521 are arranged correspondingly. That is to say, as long as it is satisfied that the first cover body 51 and the second cover body 52 can be detachably assembled through the plugging part 511 and the plugging groove 521, during production and manufacturing, the positions and numbers of the plugging groove 521 and the plugging part 511 can be set according to requirements.

[0064] In other embodiments, the first cover body 51 and the second cover body 52 can also be detachably assembled through snap fit, or directly through fastening screws.

[0065] Adopting the above technical solution, the detachable assembly between the decorative cover 5 and the lamp cover 3 can, on the one hand, replace different decorative covers 5 according to different usage scenarios, which not only improves the diversity of the use of the decorative lamp string, but also can improve the applicability of the decorative lamp string, making it applicable to more scenarios. On the other hand, directly assembling the decorative cover 5 on the lamp cover 3 can reduce the area of the decorative cover 5 on the non-light-emitting side of the light-emitting body 2, so that the light generated by the energization of the light-emitting body 2 can illuminate a larger area of the decorative cover 5, so that more parts of the decorative cover 5 can be displayed after being illuminated, improving the decorative effect of the decorative cover 5, and further improving the decorative effect of the decorative lamp string.

[0066] The above is only used to illustrate the technical solution of the present invention and is not a limitation. Other modifications or equivalent replacements made by those of ordinary skill in the art to the technical solution of the present invention should be covered within the scope of the claims of the present invention as long as they do not depart from the spirit and scope of the technical solution of the present invention.
