Description

A lamp with continuously adjustable hole position Technical Field

[0001] The utility model relates to the field of lamps, in particular to a lamp with continuously adjustable hole positions. Background Art

[0002] There are generally three types of installation methods for lamps: canister-mounted, surface-mounted, and embedded. In the Chinese patent document with the name “downlight” and the patent number CN202020883187.5, an existing embedded-mounted lamp is disclosed. Embedded installation is to set a mounting hole on the ceiling, insert the upper end of the lamp (the junction box part) into the mounting hole, and then hang it on the upper surface of the hole wall of the mounting hole by unfolding an expandable component on the lamp (usually a torsion spring assembly). In the case of hanging installation, the mounting hole must be no less than the distance between the two hanging parts. The position of the existing hanging parts is fixed to the fixed position of the lamp and cannot be changed. Therefore, a lamp can only be installed in a single installation method of one mounting hole, resulting in poor versatility during use. In addition, the existing lamp installation method can only be installed in one of the two methods of surface installation and embedded installation, which also results in a single installation method and poor versatility during use. In addition, the existing lamp mounting structure is directly set on the back of the lamp housing. In order to realize the setting of the mounting structure, multiple holes are opened on the surface of the back plate, resulting in poor sealing of the housing and direct glare when the LED is used as the light source. Summary of the Invention

[0003] The first purpose of the present invention is to provide a lamp with continuously adjustable hole position that can adapt to mounting holes of different apertures for embedded installation, thereby solving the problem of poor versatility caused by the existing lamps being able to be installed in mounting holes of only one size.

[0004] The second purpose of the present invention is to further provide a lamp with continuously adjustable hole positions that is detachably connected to a mounting frame for mounting a mounting structure, thereby solving the problem that the existing mounting structure is directly set on the back panel of the lamp, resulting in poor tightness of the lamp housing.

[0005] The third purpose of the present invention is to provide a lamp with continuously adjustable hole position and soft light output, which solves the problem of direct glare from LEDs in existing lamps.

[0006] The fourth purpose of the present utility model is to provide a lamp with continuously adjustable hole positions that can be installed in an embedded or surface manner and can adapt to different bolt hole positions when surface-mounted, thereby solving the problem of poor versatility caused by the fact that existing lamps can only be installed in one of the following ways: embedded or surface-mounted.
