Description

Technical Field

[0001] This utility model belongs to the field of downlight equipment technology, and more specifically, it relates to a downlight that can be quickly disassembled and assembled. Background Technology

[0002] Downlights are common lighting fixtures, typically embedded in ceilings or other flat surfaces to project light downwards. They are widely used in homes, offices, shops, and other public places because they not only provide good lighting effects but also maintain the simplicity and modernity of architectural decoration. Given the shortcomings of existing downlights in terms of disassembly and assembly, there is an urgent market demand for a quick-disassembly downlight. This type of downlight should have an easy disassembly mechanism, allowing maintenance personnel to quickly perform maintenance or replace the light source, thereby reducing workload and time costs. Furthermore, a quick-disassembly design helps reduce damage to the fixture caused by frequent disassembly and extends its lifespan. The technological background of a quick-disassembly downlight involves multiple aspects, including the widespread application of downlights, existing disassembly and assembly challenges, market demand, and technological innovation. With continuous technological advancements, we can expect the emergence of more efficient and convenient lighting solutions to meet the lighting needs of different scenarios.

[0003] Based on the above, in existing technologies, the installation and disassembly of downlights typically involve multiple steps and tools, making the installation and maintenance process complex and time-consuming. For example, some surface-mounted downlights require the base to be bolted to the ceiling before installation, and then clips are used to attach the downlight body to the base. While this design provides stability during installation, it increases the workload for workers when disassembly or repair is needed, and may also lead to damage to the light fixture.
