[0006] The portion of the downlight hanging ear outside the downlight housing body can be bent toward the location of the downlight housing body, so that after bending, it can be inserted into the mounting hole together with the top of the downlight housing body, and then naturally stretch after letting go to clamp the top of the downlight housing body;

[0007] The downlight housing body is provided with a plurality of buckles, and the buckles cooperate with the flanges on the light source board to clamp the light source board;

[0008] The flange of the light source board located at the ear slot forms an upper cover for the ear slot and the downlight ear in the ear slot. The problem of the ear getting loose can be effectively solved by pressing the downlight ear with the flange of the light source board and cooperating with the ear slot and multiple buckles on the downlight housing body.

[0009] While adopting the above technical solutions, the present invention may also adopt or combine the following technical solutions:

[0010] As a preferred technical solution of the present invention: the downlight hanging ear is in the shape of an elastic sheet as a whole.

[0011] As a preferred technical solution of the present invention: the downlight hanging ear comprises an inclined section and a horizontal section, and the horizontal section of the downlight hanging ear is locked in the hanging ear groove.

[0012] As a preferred technical solution of the present invention: one end of the downlight hanging ear in the hanging ear groove is an L-shaped end.

[0013] As a preferred technical solution of the present invention: the ear-hanging groove is wavy in shape to fit the downlight ear and is used to lock the L-shaped end of the downlight ear.

[0014] As a preferred technical solution of the present invention: the upper part of the buckle has a downward sliding slope, which serves as the downward sliding surface for the light source board to slide down, and the lower part of the buckle has a locking slope and a locking vertical surface, and the locking slope is connected to the locking vertical surface and the two cooperate to lock the light source board to the downlight housing.

[0015] As a preferred technical solution of the present invention: a diffusion plate is provided on the downlight housing body, and the diffusion plate has a plurality of protrusions so that the diffusion plate can be fixed to the injection mold and formed integrally with the downlight housing body.

[0016] The present invention provides a downlight housing, which can clamp a light source board by arranging a plurality of buckles on the downlight housing body; by arranging a hanging ear groove near the buckle, and clamping and fixing the downlight hanging ear in the hanging ear groove, it is avoided to install and fix it by using a spring hanging ear fixing method; in addition, by making one end of the downlight hanging ear in the hanging ear groove an L-shaped end, the fixing effect between the downlight hanging ear and the hanging ear groove can be improved, and in addition, a wavy hanging ear groove can be arranged on this basis to prevent the downlight hanging ear in the hanging ear groove from being pulled out; by arranging a plurality of protrusions on the diffusion plate, and making the diffusion plate fixed to the injection mold and the downlight housing body integrally formed, thereby reducing the installation workers or users to install the diffusion plate, and because the diffusion plate and the downlight housing body are integrally formed, the problem of loosening of the diffusion plate will not occur, and in addition, because the diffusion plate has a plurality of protrusions, the diffusion plate is firmly fixed to the injection mold by the protrusions, so that the downlight housing body will not have position deviation with the diffusion plate during injection molding. The downlight housing provided by the present invention is simple in design, convenient to install, and has high production efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

[0024] The present invention will be described in further detail with reference to the accompanying drawings and specific embodiments.

[0025] A downlight housing comprises a downlight housing body 100, the downlight housing body 100 is provided with a plurality of buckles 120, and the buckles 120 are used for clamping a light source board 110;

[0026] The upper part of the clip 120 has a downward slope 121, which serves as the downward sliding surface for the light source board 110 to slide down. The lower part of the clip 120 has a locking slope 122 and a locking vertical surface 123. The locking slope 122 is connected to the locking vertical surface 123 and the two cooperate to lock the light source board 110 to the downlight housing.

[0027] The light source board 110 has a plurality of flanges 111, which cooperate with the buckles 120 on the downlight housing body 100 to clamp the light source board 110; the flange 111 of the light source board 110 located at the ear groove 130 forms an upper cover for the ear groove 130 and the downlight ear 140 in the ear groove 130, and the downlight ear 140 is pressed by the flange 111 of the light source board 110 and cooperates with the ear groove 130 and the plurality of buckles 120 on the downlight housing body 100, so as to effectively solve the problem of the ear loosening.

[0028] The downlight housing body 100 is provided with a hanging ear groove 130 near two of the buckles 120, and the hanging ear groove 130 is used to clamp and fix the downlight hanging ear 140. One end of the downlight hanging ear 140 in the hanging ear groove 130 is an L-shaped end 140a, and the hanging ear groove 130 is wavy to fit the downlight hanging ear 140 and is used to lock the L-shaped end 140a of the downlight hanging ear 140. In this embodiment: the downlight hanging ear 140 includes an inclined section 141 and a horizontal section 142, and the horizontal section 142 of the downlight hanging ear 140 is locked in the hanging ear groove 130, and the end of the horizontal section 142 of the downlight hanging ear 140 is the L-shaped end 140a. In this embodiment, two hanging ear grooves 130 are provided and matched with two downlight hanging ears 140. The extension directions of the downlight hanging ears 140 are opposite to each other so as to form a Z-shaped arrangement between the downlight housing body 100, so that the top of the downlight housing can be clamped and fixed by respectively extending the two downlight hanging ears 140 into the corresponding mounting holes on the top of the downlight housing.
