Description

A lamp with continuously adjustable hole position

Technical Field

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

Background technique

There are generally three installation methods for lamps: tube-mounted, surface-mounted, and embedded. In the Chinese patent document with the name of "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 (junction box part) into the mounting hole, and install it by unfolding the unfoldable parts on the lamp (usually a torsion spring assembly) and hanging it on the upper surface of the hole wall of the mounting hole. When hanging, the mounting hole must not be less than the distance between the two hanging parts. The position of the existing hanging parts is fixed at the fixed position of the lamp and cannot be changed, so a lamp can only be used for a single installation method of a mounting hole, resulting in poor versatility during use; in addition, the existing installation method of the lamp can only be installed in one of the surface installation and embedded installation methods, which also results in a single installation method and poor versatility during use. In addition, the existing lamp installation structure is directly set on the back of the lamp housing. In order to realize the installation of the installation 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

The first purpose of the utility model is to provide a hole position continuously adjustable lamp that can adapt to installation holes of different apertures for embedded installation, thereby solving the problem of poor versatility caused by the fact that existing lamps can only be installed in installation holes of one size.

The second object of the utility model is to further provide a lamp with continuously adjustable hole positions, which is detachably connected to a mounting frame for mounting a mounting structure, thereby solving the problem that the existing mounting structure is directly arranged on the back plate of the lamp, resulting in poor tightness of the lamp housing.

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

The fourth purpose of the utility model is to provide a lamp with continuously adjustable hole positions that can be embedded or surface-mounted 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.
