With the continuous development of science and technology, the application field of LED light source is becoming more and more extensive. Among the many LED decorative lighting fixtures, panel lights are a more common one. Panel lights are widely used in shopping malls, large supermarkets, office places, museums, exhibition halls, hotels, high-end residences, etc. as important lighting products, which can not only brighten the environment, but also beautify the environment and add color to life.

[0003] A Chinese utility model patent application with application number 202222745323.6 (publication number CN 218721079 U) discloses a small panel lamp, which includes a lamp housing with a downward opening cavity, a light-emitting component arranged in the lamp housing, a light-guiding component arranged in the lamp housing, and a diffusion plate arranged below the light-guiding component corresponding to the opening and covering the light-guiding component, the edge of the lamp housing is provided with a flange turned outward along the circumferential direction, and a ring-shaped cover plate is fixedly provided below the flange to match the flange, and the inner edge of the cover plate extends upward and integrally with a support plate that is supported on the light-guiding component, and the diffusion plate is limited on the support plate. The diffusion plate in the above patent is located inside the cavity of the lamp housing, and the edge of the diffusion plate is blocked, so that the light diffused on the diffusion plate can only diffuse vertically downward, and the angle of the light diffused by the entire diffusion plate is small, which affects the lighting effect; and the cover plate structure will waste the light output area and affect the aesthetics of the outer surface of the small panel lamp.

[0004] In order to solve the above problems, a Chinese utility model patent application with application number 202420380751.X discloses a small panel lamp, which includes a lamp housing with a downward opening cavity, a light-emitting component arranged in the lamp housing, a light guide component arranged in the lamp housing and a diffusion plate arranged below the light guide component, and also includes a first connecting ring mounted on the outer peripheral wall of the lamp housing, the inner ring edge of the first connecting ring is connected to the outer peripheral wall of the lamp housing; the diffusion plate includes a bottom plate and a side wall plate extending upward from the periphery of the bottom plate, the inner peripheral wall of the side wall plate is connected to the outer ring edge of the first connecting ring. The inner peripheral wall of the side wall plate of the diffuser plate is connected to the outer ring edge of the first connecting ring, and the diffuser plate wraps the opening of the lamp housing. The light emitting area of ​​the diffuser plate is larger than the light emitting area of ​​the light guide component, and the light can also be emitted from the side wall plate of the diffuser plate, so that the light emitting angle of the light when it is emitted from the diffuser plate is increased, and the maximum can reach 180 degrees, that is, it can be emitted from an angle parallel to the light guide component; the existing light emitting mode of the lamp is improved, so that the light emitting area and angle are larger, the light is softer, and the glare is less.

[0005] However, in this technical solution, the inner ring edge and the outer ring edge of the first connecting ring are respectively connected to the outer peripheral wall of the lamp housing and the inner peripheral wall of the side wall plate, and the first connecting ring extends in the horizontal direction. The luminous intensity of the part of the base plate below the first connecting ring is lower than the luminous intensity of the part of the base plate below the light guide assembly, and the luminescence of the base plate is not uniform enough; in addition, in order to ensure the luminous intensity of the part of the base plate directly below the first connecting ring, the distance between the base plate and the first connecting ring in the vertical direction is often large, which will undoubtedly increase the thickness of the lamp.
