[0009] In this way, during assembly, the LED lamp strip is bonded in the mounting groove of the mounting cylinder, the light transmission plate, the light uniforming plate and the light reflection plate are sequentially placed in the mounting cylinder, the mounting cylinder is inserted into the ring groove, and the mounting cylinder and the mounting seat are fixedly connected through screws, so that the assembly is completed. The down lamp can be installed at the hole position in the ceiling after the hole is opened.

[0010] Among them, the outer periphery of the decorative plate is upwardly bent to form a blocking ring.

[0011] Wherein, the installation tube is fixedly mounted with a plurality of peripheral heat dissipation fins arranged at intervals on the periphery of the light strip.

[0012] Wherein, a plurality of top heat dissipating fins distributed radially are fixedly mounted on the mounting base.

[0013] Wherein, a guide ring is fixed upward on the decorative plate.

[0014] In summary, the thin embedded downlight has the advantages of being easy to install, being able to dissipate heat, and avoiding light leakage. BRIEF DESCRIPTION OF THE DRAWINGS

[0019] The present invention is further described in detail below with reference to the accompanying drawings. In the description of the present invention, it should be understood that the directions or positional relationships indicated by directional terms such as "upper, lower" and "top, bottom" are generally based on the directions or positional relationships shown in the accompanying drawings and are intended only to facilitate the description of the present invention and simplify the description. Unless otherwise indicated, these directional terms do not indicate or imply that the devices or components referred to must have a specific direction or be constructed and operated in a specific direction, and therefore should not be understood as limiting the scope of protection of the present invention; the directional terms "inside" and "outside" refer to the inside and outside relative to the outline of each component itself.

[0020] like Figure 1-4As shown, a thin embedded downlight comprises a lamp housing and a mounting base 1, and spring clips 2 are installed on both sides of the mounting base; the lamp housing comprises a decorative panel 3 and a mounting tube 4, the decorative panel is provided with a light-transmitting hole, the mounting tube is located on the outside of the light-transmitting hole, and a light-transmitting plate 5, a light-diffusing plate 6 and a reflective plate 7 are placed in sequence in the mounting tube, the lower end of the light-transmitting plate abuts against the part of the decorative panel protruding from the inner side of the mounting tube, and the reflective plate abuts against the mounting base; the mounting base is provided with an annular groove, the upper end of the mounting tube is plugged into the annular groove, and the mounting base and the mounting tube are fixedly connected by screws; the mounting tube is provided with a mounting groove protruding outwardly facing the light-diffusing plate, an LED light strip 8 is bonded in the mounting groove, the LED light strip is arranged facing the light-diffusing plate, the light strip is connected outwardly with a light source output line, and a wire hole is provided on the mounting tube.

[0021] During assembly, glue the LED light strip into the mounting groove of the mounting tube, place the light-transmitting plate, light-diffusing plate, and light-reflecting plate in the mounting tube in sequence, insert the mounting tube into the ring groove, and securely connect the mounting tube and the mounting base with screws to complete the assembly. Then, drill a hole in the ceiling and install the downlight in the hole.

[0022] During implementation, the outer circumference of the decorative plate is bent upward to form a retaining ring 9. The retaining ring abuts against the ceiling to reduce dust from entering the downlight position through the gap.

[0023] During implementation, the mounting tube is fixedly mounted with a plurality of peripheral heat dissipation fins 10 arranged at intervals on the periphery of the light strip to improve the heat dissipation effect.

[0024] During implementation, a plurality of top heat dissipating fins 11 arranged in a radial pattern are fixedly mounted on the mounting base to improve the heat dissipation effect.

[0025] During implementation, the decorative plate is upwardly fixed with a guide ring 12. The guide ring is matched with the opening on the ceiling in a contoured manner for easy installation.

[0026] In this application, the mounting portion is formed by the outer protrusion of the mounting tube, and the LED light strip is set corresponding to the light-diffusing plate. The upper end of the mounting tube is inserted into the mounting seat, and the lower end is fixed to the decorative plate and away from the light-transmitting hole. This allows the light emitted by the LED light strip to be evenly distributed through the light-diffusing plate, and the reflector to reflect the light, so that the light is projected through the light-transmitting plate, avoiding light leakage. The light source output line is externally connected to the power drive.

[0027] Finally, it should be noted that those skilled in the art may make various modifications and variations to the present invention without departing from the spirit and scope of the present invention. Thus, if such modifications and variations fall within the scope of the claims and their equivalents, the present invention is intended to include such modifications and variations.
