[0002] Light bulbs are a common lighting structure, characterized by low power consumption, long lifespan, and ease of use, and are widely used in various fields. In existing technologies, light bulbs generally include a lamp holder, a light source, and a light-transmitting cover. Although this can meet the general usage needs, the large illumination range of light bulbs can lead to light waste, affecting the lighting effect and limiting their applicability. Summary of the Invention

[0003] The purpose of this invention is to provide a light bulb with a replaceable lampshade that has a reasonable structural design and strong applicability.

[0004] The technical solution to achieve the purpose of this utility model is a bulb with a replaceable lampshade, including a lamp holder, a lamp head fixed on the lamp holder, a driving circuit board connected to the lamp head and a light source connected to the driving circuit board inside the lamp holder, and a diffusion lens fixed at the bottom of the lamp holder.

[0005] The bottom surface of the lamp holder has several mounting screw holes;

[0006] The lamp holder has a lampshade on its bottom surface, the top of the lampshade is attached to the bottom surface of the lamp holder and fixed with screws, and the diffuser lens is located inside the horn-shaped lampshade.

[0007] A further preferred embodiment is that the lampshade is a hemispherical lampshade, a trumpet-shaped lampshade, a cylindrical lampshade, or a frustum-shaped lampshade.

[0008] A further preferred embodiment is that the diffusion lens is a concave lens.

[0009] A further preferred embodiment is that a lower vent is provided at the bottom edge of the lamp holder.

[0010] This utility model has positive effects: The structure of this utility model is reasonable. It has mounting screw holes on the bottom surface of the lamp holder and matches the lamp cover. The lamp cover is fixed to the bottom surface of the lamp holder with screws. This not only improves the convenience of installation, but also makes it easy to replace different lamp covers as needed, thereby meeting the usage needs of different situations. In addition, the lamp cover can also reduce light waste and improve the lighting effect, making it highly applicable. Attached Figure Description

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Example

[0019] See Figures 1 to 3 As shown, a replaceable lampshade bulb includes a lamp holder 1, a lamp head 2 fixed on the lamp holder, a drive circuit board 3 connected to the lamp head and a light source 4 connected to the drive circuit board are disposed inside the lamp holder, and a diffusion lens 5 is fixed at the bottom of the lamp holder; in this embodiment, the lamp head, drive circuit board and light source are all conventional structures of the prior art, and are simply applied.

[0020] Furthermore, in this embodiment, the bottom surface of the lamp holder is provided with several mounting screw holes 6; a lampshade 7 is provided on the bottom surface of the lamp holder, the top of the lampshade is attached to the bottom surface of the lamp holder and fixed by screws 9, and the diffuser lens is located inside the horn-shaped lampshade. This structure improves the convenience and stability of lampshade installation, and also allows for quick replacement of different lampshades as needed to meet the usage requirements of different situations.

[0021] In this embodiment, the lampshade is a hemispherical lampshade. The diffusion lens is a concave lens.
