[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Example

[0024] See Figures 1 to 3As shown, a combined projection lamp structure includes a ceiling-mounted panel 1 and a projection housing 2 disposed on the ceiling-mounted panel. A projection base 3 is fixed to the side wall of the projection housing, and a projector body 4 is fixed inside the projection base. In this embodiment, the ceiling-mounted panel is a conventional structure of the prior art, mainly used for installation on the ceiling or other locations. The projection housing can be cylindrical, frustum-shaped, or other shapes to improve aesthetics. For easy connection, the top surface of the projection housing is provided with a circular cavity, a square cavity, a cross-shaped cavity, or an I-shaped cavity. In this embodiment, a circular cavity 5 is used, specifically as shown below. Figures 1 to 2 As shown in the diagram, the upper part of the inner wall of the circular, square, cross-shaped, or I-shaped cavity is provided with a locking protrusion 6; the edge of the ceiling mounting plate is provided with a buckle protrusion 7; during assembly, the ceiling mounting plate is inserted into the circular, square, cross-shaped, or I-shaped cavity, causing the locking protrusion and the buckle protrusion to engage and position. This improves the convenience and effectiveness of installation. The projector base can be detachably fixed to the projector housing or integrally formed on the projector housing. The projector body has a conventional structure in existing technology, mainly used for projection playback. It can be connected to a mobile APP and can also realize remote control or intelligent control operation to meet the needs of different situations. In practical applications, the projector body can be a round projector body or a projector body of other shapes, and it is also provided with spare mounting holes on the projector base.

[0025] In this embodiment, a support base 8 is provided at the bottom of the projection housing, and the projector body is mounted on the projection base and positioned by the support base. Several mounting holes 9 are provided along the edge of the projection housing. A lamp body 10 is attached to the bottom surface of the projection housing and is fixed by screws passing through the mounting holes. The support base is fixed to the bottom of the projection housing by screws or clips. A corresponding intelligent controller or driving power supply can be installed between the support base and the projection housing. Furthermore, the support base allows the projection housing and the projector body to be used separately in combination.

[0026] In this embodiment, the projector body is inclined downwards within the projection base, and an inclined support protrusion 11 is fixed to the top surface of the support base; the inclined top surface of the inclined support protrusion abuts against the bottom surface of the projector body. This structure allows the projector body to project downwards at a certain angle, specifically, the projector body's tilt angle is 20-50 degrees, satisfying different projection angle requirements. The inclined support protrusion is mainly used to support and limit the projector body, ensuring a stable and reliable installation position.

[0027] In practical applications, the projector body is horizontally positioned within the projection base, and the top surface of the support base is flat, with the flat surface of the support base abutting against the bottom surface of the projector body for positioning. This also enables horizontal projection operations.

[0028] The bottom surface of the projection housing is provided with a foot 12; the top surface of the lamp body is attached to the bottom surface of the foot for positioning. This creates a gap between the lamp body and the bottom surface of the projection housing to facilitate heat dissipation.

[0029] In this embodiment, the lamp body is a ceiling light, floodlight, downlight, spotlight, fan light, or chandelier. Different lamp bodies can be selected as needed to expand its applicability. Furthermore, the lamp body can be a conventional lamp body or a smart control lamp body; it is simply a matter of application.

[0030] This utility model has positive effects: its structure is reasonably designed, with a projection base fixed on the side wall of the projection housing and the projector body fixed inside the projection base. This not only achieves the projector effect, but also allows the lamp body to be fixed to the bottom surface of the projection housing by screws, thus enabling downward illumination. Furthermore, different lamp bodies can be replaced as needed, which improves ease of use, meets the needs of different situations, facilitates inspection and maintenance, and has strong applicability.

[0031] The standard parts used in this embodiment can be purchased directly from the market, and the non-standard structural parts described in the instruction manual can also be processed without any doubt based on existing technical common sense. At the same time, the connection methods of each component adopt mature conventional methods in the existing technology, and the machinery, parts and equipment all adopt conventional models in the existing technology, so they will not be described in detail here.

[0032] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating this utility model, and are not intended to limit the implementation of this utility model. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all embodiments here. However, these obvious variations or modifications derived from the essential spirit of this utility model still fall within the protection scope of this utility model.
