Description

Technical Field

[0001] The utility model relates to the technical field of lighting fixtures, in particular to a lighting fixture capable of replacing a lamp shade. Background Art

[0002] Lighting fixtures are essential lighting devices in daily life and are often fixed to the top of indoor rooms for use. Most current lighting fixtures are directly screwed into the fixed lighting fixture conductive base on the roof. Generally, they consist of a lamp shade and a lamp base, with a light bulb installed inside. However, the lamp shades of such lighting fixtures are directly integrally injection-molded with the lamp base. When the lamp shade is damaged, it is impossible to only disassemble and replace the lamp shade, and the entire lighting fixture has to be replaced, resulting in an increase in maintenance costs and a waste of resources. Summary of the Utility Model

[0003] The purpose of the utility model is to provide a lighting fixture capable of replacing a lamp shade to overcome the defects existing in the above-mentioned prior art.

[0004] The purpose of the utility model can be achieved through the following technical solutions:

[0005] A lighting fixture capable of replacing a lamp shade, the lighting fixture includes a lamp shade and a lamp base; an external thread is provided on the outer circumference of the top of the lamp shade; an internal thread matching the external thread is provided on the inner circumference of the bottom of the lamp base; a light bulb is connected to the bottom of the lamp base; the light bulb is located in the middle of the lamp shade and is electrically connected to the bottom of the lamp base; a conductive member for installation, fixation and power-on is provided on the top of the lamp base.

[0006] Further, the lamp shade is a cylindrical lamp shade; the lamp shade is a light-transmitting lamp shade made of a transparent material.

[0007] Further, the conductive member is a conductive member with an external thread structure; the conductive member is a conductive member made of a metal conductive material.

[0008] Further, heat dissipation openings for the heat dissipation of the light bulb and the lighting fixture are symmetrically provided on the lamp shade.

[0009] Further, the lamp base is a lamp base made of a plastic material.

[0010] Compared with the prior art, the utility model has the following advantages:

[0011] (1) Through the design of the external thread of the lamp shade and the internal thread of the lamp base, and the mutual cooperation of the threaded connection for fixation, the utility model can realize the disassembly and replacement of the lamp shade. When the lamp shade is damaged, only the lamp shade can be replaced separately without replacing the entire lighting fixture. The structure is simple, the maintenance cost is reduced, and resources are saved; and when the light bulb burns out, the lamp shade can also be disassembled to replace the light bulb.

[0012] (2) The utility model is provided with heat dissipation openings on the outer ring of the lamp holder, which can achieve the heat dissipation inside the lamp and prevent the lamp from being burned due to excessive temperature. Description of the Drawings

[0016] To make the objectives, technical solutions, and advantages of the embodiments of the utility model clearer, the technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the utility model. Apparently, the described embodiments are some but not all of the embodiments of the utility model. Usually, the components of the embodiments of the utility model described and illustrated herein can be arranged and designed in various different configurations.

[0017] Therefore, the following detailed description of the embodiments of the utility model provided in the drawings is not intended to limit the scope of the claimed utility model, but merely represents the selected embodiments of the utility model. Based on the embodiments in the utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the utility model.

[0018] It should be noted that similar reference numerals and letters denote similar items in the following drawings. Therefore, once an item is defined in one drawing, it does not need to be further defined and explained in subsequent drawings.

[0019] In the description of the utility model, it should be noted that the orientation or positional relationship indicated by the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc. is based on the orientation or positional relationship shown in the drawings, or the orientation or positional relationship in which the utility model product is usually placed during use. It is only for the convenience of describing the utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus should not be construed as a limitation of the utility model.

[0020] It should be noted that the terms "first" and "second" are only used for descriptive purposes and should not be construed as indicating or implying relative importance or implicitly specifying the quantity of the indicated technical features. Thus, features defined with "first" and "second" may explicitly or implicitly include one or more of such features.
