[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, a downlight that is easy to install includes a lamp housing main body, a lighting module and a hook assembly, wherein the lamp housing main body includes a mounting back plate and an outer lamp housing; the mounting back plate and the outer lamp housing are connected by a snap-fit; the lighting module is installed between the mounting back plate and the outer lamp housing; multi-purpose mounting holes are provided on the mounting back plate; the number of the multi-purpose mounting holes is at least two; the hook assembly is detachably connected to the mounting back plate through the multi-purpose mounting holes.

[0024] The multi-purpose mounting hole comprises a central hole and an expansion slot extending outward from the central hole; the number of the expansion slots is two and they are perpendicular to each other; the width of the expansion slot is smaller than the diameter of the central hole;

[0025] The hook assembly can be installed through the multi-purpose mounting hole to adapt to the American standard downlight holder, and can also be installed in an octagonal box. When neither of the above two installation environments is met, the center hole design can also support direct installation and fixation through expansion screws.

[0026] The hook assembly includes a spring hook, a hook mounting seat and a mounting screw; the hook mounting seat is provided with a fixing screw hole, a positioning protrusion and a hook connecting ring; during installation, the fixing screw hole corresponds to the center hole on the multi-purpose mounting hole, and the positioning protrusion can be stuck in the expansion slot to assist in fixing and prevent the hook mounting seat from shifting, so that the hook mounting seat can be well fixed with only one screw; the spring hook is connected to the hook mounting seat through the hook connecting ring, and through the hook assembly, the downlight can be adapted to the American standard downlight holder for fixed installation.

[0027] In addition to adapting to the American standard downlight holder through the hook assembly, it can also be fixed and installed directly by directly matching the vertical expansion slot on the multi-purpose mounting hole with the screw hole on the octagonal box; since the octagonal box has various specifications, the screw holes on it also have various spacings, so the expansion slots with a certain length and perpendicular to each other can flexibly adapt to octagonal boxes of various specifications, improving versatility;

[0028] Since both the octagonal box and the American standard downlight holder need to be pre-buried, if the above two installation conditions are not met, the downlight can also be installed by using expansion screws. The larger diameter of the center hole is designed for this situation.

[0029] Several connecting buckles are arranged on the edge of the outer lamp shell; quick-release connecting holes corresponding to the connecting buckles are arranged on the mounting back plate; the quick-release connecting hole is composed of two sections, one wide and one narrow. The connecting buckles are aligned with the wider section of the quick-release connecting hole and inserted, and the outer lamp shell can be quickly connected to the mounting back plate by rotating it a certain angle. The outer lamp shell can be quickly removed by rotating it in the opposite direction, which is convenient for later maintenance, replacement or upgrading of the lighting module without disassembling the entire lamp; for the convenience of users, an indicator mark indicating the rotation direction for installation / disassembly is also provided on the outer lamp shell.

[0030] The power cord of the lighting module passes through the installation backplate, and the line can be hidden during installation to ensure aesthetics; to ensure the heat dissipation of the lighting module and prevent heat accumulation, the installation backplate is usually a metal plate, and the fitting of the lighting module and the metal plate can assist in heat dissipation; since a metal casing is used, it needs to be grounded, so an elastic metal sheet is provided between the lighting module and the installation backplate, so that the lighting module and the installation backplate can always maintain electrical connection even if a gap appears between them, which is more stable and reliable than the direct contact grounding method; a grounding wire is provided on the installation backplate; the grounding wire and the installation backplate are fixedly connected by screws.

[0031] Since a plurality of LED lamp beads are usually arranged on the PCB board of the lighting module as light sources, in order to ensure a good lighting effect of the downlight, a light-uniform cover is also arranged on the lighting module, which, together with the translucent outer lamp shell, can prevent the downlight from having uneven brightness.

[0032] Advantages of the utility model:

[0033] A multi-purpose mounting hole is provided on the mounting back plate; the multi-purpose mounting hole comprises a center hole and an extension slot extending outward from the center hole; the number of the extension slots is two and they are perpendicular to each other; the width of the extension slot is smaller than the diameter of the center hole; through the multi-purpose mounting hole, the downlight can be installed with a hook assembly adapted to an American standard downlight holder, adapted to an octagonal box for fixed installation, or directly fixed with expansion screws; the design of the extension slot also enables the downlight to be compatible with a variety of octagonal boxes of different specifications, greatly improving the versatility of the downlight and making it more flexible to use.

[0034] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any changes or substitutions that can be easily thought of by any technician familiar with the technical field within the technical scope disclosed in the utility model should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model shall be based on the protection scope of the claims.
