[0002] Lighting fixtures are a general term for lighting tools, referring to devices that transmit, distribute, and alter the light distribution of a light source. This includes all components necessary for fixing and protecting the light source, excluding the light source itself, as well as the wiring accessories necessary for connecting to a power source. In daily life, various types of lighting fixtures are used depending on the scenario, such as table lamps, ceiling lamps, pendant lamps, and wall lamps. Among these, square lighting fixtures are widely used due to their flat shape, small footprint, and good overall lighting effect.

[0003] Currently, square lamps on the market generally have many problems. For example, it is very inconvenient to replace the lampshade when installing the lamp. Users need to disassemble and reassemble many parts to complete the reassembly, which takes a long time and requires users to be skilled. Users also need to hold the lampshade for a long time, and it is easy to drop and break it if they are not careful. Users also need to look up for a long time, resulting in a poor user experience. Therefore, a square lamp with an easy-to-replace lampshade is proposed. Utility Model Content
