Description

Technical Field

[0001] This utility model relates to the field of spotlight technology, and in particular to a circular surface-mounted spotlight. Background Technology

[0002] With the development of the interior decoration industry, surface-mounted downlights have become widely used in commercial spaces, home environments, and other lighting scenarios due to their combination of practicality and aesthetics. Compared to recessed downlights, surface-mounted downlights do not require complex ceiling pre-installation. Their installation method is similar to that of panel lights, and they can be fixed using screws pre-installed on the ceiling, making operation convenient and significantly enhancing the decorative effect of the space. The structure of a surface-mounted downlight mainly consists of a lamp body and an outer cover. The outer cover is fixed to the ceiling via a mounting plate structure. This structural design ensures the stable installation and visual appeal of the surface-mounted downlight.

[0003] Currently, in existing surface-mounted downlights, the connection between the mounting plate structure and the outer casing is typically achieved using bolts or direct welding. Bolting requires pre-drilling multiple mounting holes in both the mounting plate and the outer casing, then screwing in bolts one by one. This not only results in a cumbersome and time-consuming assembly process, reducing production efficiency, but also increases maintenance costs due to the significant time and effort required for disassembly and maintenance. While welding ensures connection strength, the welding process is prone to deformation, affecting the appearance and dimensional accuracy of the outer casing. Furthermore, once welded, the outer casing and mounting plate structure are difficult to separate, hindering individual component replacement and severely limiting product repair and upgrades. Additionally, welding residue detracts from the overall aesthetics of the outer casing, reducing the product's decorative value. Therefore, a new method for connecting the mounting plate structure to the outer casing is urgently needed to overcome the problems of low assembly efficiency, inconvenient maintenance, and unsatisfactory appearance inherent in existing technologies.
