[0027] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention. Example

[0028] See Figures 1 to 5 The figure shows a ceiling-mounted bulb that fits snugly on the ceiling. It is connected to a lamp holder 2 within a ceiling 1. In this embodiment, the lamp holder is embedded or clipped into the ceiling, a conventional structure in the prior art. It includes a connecting lamp holder 3, a flat plate lamp body 4 secured to the bottom surface of the connecting lamp holder, a light source panel 5 and a diffuser 6 disposed on the bottom surface of the flat plate lamp body. The flat plate lamp body is made of aluminum, and both the light source panel and diffuser are conventional structures in the prior art and are simply used. The connecting lamp holder is either an external screw-on lamp holder or a clip-on lamp holder, making it easy to connect and use.

[0029] In this embodiment, the bottom edge of the flat panel lamp body is integrally formed with a convex edge 7, and the bottom end of the convex edge is bent inward to form a supporting ridge 8; the height of the convex edge and the supporting ridge can be processed and set as needed to meet the assembly requirements of different thicknesses.

[0030] The top edge of the flat panel lamp body is integrally formed with a retaining ring 9. An elastic retaining ring 10 is fixed to the top of the inner wall of the retaining ring. The top surface of the elastic retaining ring protrudes from the top surface of the retaining ring. The height of the elastic retaining ring protrudes from the retaining ring by 1-2 cm. Therefore, when connected to the lamp holder on the ceiling, the retaining ring will be close to the bottom surface of the ceiling, and the elastic retaining ring will simultaneously press against the bottom surface of the ceiling and deform, achieving seamless retaining.

[0031] During assembly, the light source board is fixed to the bottom surface of the flat panel lamp body, the edge of the diffuser is positioned against the upper limit of the support ridge, and a driver 11 is fixed to the top surface of the flat panel lamp body. The connecting lamp head is connected to the driver via a wire, and the driver is connected to the light source board via a power supply. The connecting lamp head is connected to the lamp holder, and the top surface of the elastic retaining ring seamlessly abuts the bottom surface of the ceiling. The driver adopts a conventional structure of the prior art and is simply applied. The height of the retaining ridge is less than that of the connecting lamp head and greater than that of the driver.

[0032] In actual application, the elastic retaining ring is a rubber ring or a silicone ring. It can also be a retaining ring with other soft properties, mainly being able to deform and retain on the bottom surface of the ceiling.

[0033] In this embodiment, the connecting lamp holder and the flat plate lamp body are fixed by screws or buckles. The flat plate lamp body is circular.

[0034] The present invention has positive effects: the structure of the present invention is reasonably arranged, and there is a convex edge on the bottom edge of the flat panel lamp body, and a positioning convex ring is provided on the top edge of the flat panel lamp body to cooperate with the elastic positioning ring. When the lamp head is connected to the lamp holder on the ceiling, the positioning convex ring can be attached to the bottom surface of the ceiling, and the elastic positioning ring is seamlessly positioned on the bottom surface of the ceiling, thereby improving the effectiveness of the fit between the bulb and the ceiling. Long-term use can prevent dust from entering the top surface of the flat panel lamp body, which is beneficial to improving the service life of the bulb. Moreover, the overall height of the bulb can be reduced after assembly, thereby improving the aesthetics of the assembly, and the use is stable and reliable, and the applicability is strong. Example

[0035] See Figure 6 As shown, this embodiment is basically the same as embodiment 1, except that the flat panel lamp body is square. Example

[0036] See Figure 7 As shown, this embodiment is basically the same as embodiment 1, except that: the flat panel lamp body is a regular polygon, specifically a regular hexagon. Example

[0037] See Figure 8 As shown, this embodiment is basically the same as embodiment 1, except that: the flat panel lamp body is elliptical, and in actual application, it can also be other shapes such as crescent or star.

[0038] The standard parts used in this embodiment can be purchased directly from the market, and the non-standard structural components described in the specification can also be directly processed according to existing technical common sense without any doubt. At the same time, the connection method of each component adopts the mature conventional means in the existing technology, and the machinery, parts and equipment all adopt conventional models in the existing technology, so no specific description is given here.

[0039] Obviously, the above embodiments of the present invention are merely examples for the purpose of clearly illustrating the present invention and are not intended to limit the embodiments of the present invention. Those skilled in the art will readily appreciate that other variations or modifications based on the above description are possible. It is not necessary and impossible to enumerate all embodiments here. However, obvious variations or modifications arising from the essence of the present invention remain within the scope of protection of the present invention.
