[0038] Based on the above technical solution, the embedded lamp includes a heat sink 1, a lamp body fixing ring 3, and an anti-glare optical component 2. A plurality of longitudinal convex ribs 31 are arranged on the inner wall of the lamp body fixing ring 3 to form a grating structure, which can effectively reduce irregular residual light and improve the edge quality of the light spot. The overall structure is simple, reliable, and easy to implement.

The texture can make the transmitted light uniform and soft, which plays an anti-glare purpose. The grating structure further optimizes the residual light of the light to improve the quality of the light spot. Furthermore, the optical component 23 is a light-transmitting compound eye light sheet (i.e., a diffuser light sheet), and the stripes are concave-convex structures. Furthermore, the longitudinal convex ribs 31 are evenly arranged on the inner circumferential wall of the lamp body fixing ring 3 in a circumferential direction.

[0040] In a preferred embodiment, in combination Figure 8 As shown in , the embedded lamp also includes a rotating ring 4 hinged to the lower end of the lamp body fixing ring 3, and the rotating ring 4 can be tilted and flipped relative to the lamp body fixing ring 3 to adjust the projection angle of the light emitted from the light-emitting end of the anti-glare optical component 2. Further, the outer periphery of the lower end of the lamp body fixing ring 3 has two symmetrically arranged ear seat structures 32, each ear seat structure 32 is provided with a mounting hole, and the inner peripheral wall of the rotating ring 4 has a connecting shaft 45 that matches the shape of the mounting hole and is opposite in position, so that the connecting shaft 45 can be installed in the mounting hole to achieve the purpose of hinge.

[0041] As a further preferred embodiment, the upper end surface of the rotating ring 4 is formed with a first curved surface structure 44 in the shape of a slope, and the lower end surface of the lamp body fixing ring 3 is provided with a second curved surface structure 36 matching the shape of the first curved surface structure 44, and the first curved surface structure 44 and the second curved surface structure 36 are arranged oppositely, which can effectively solve the light leakage problem in the movable assembly state of the two. Further, the lamp body fixing ring 3 is also provided with a locking structure 34, and the locking structure 34 is used to lock the position of the lamp body fixing ring 3 and the rotating ring 4 after relative rotation.

[0042] In a preferred embodiment, the embedded lamp also includes a mounting surface ring 7 mounted on the outer periphery of the rotating ring 4, and an anti-glare cover 5 accommodated inside the mounting surface ring 7, and the rotating ring 4 can rotate circumferentially relative to the mounting surface ring 7, and the upper part of the anti-glare cover 5 extends into the rotating ring 4 and is connected to the inner wall of the rotating ring 4, so as to further refract the light after refraction by the optical component 23 and removal of residual light by the grid structure on the inner wall of the anti-glare cover 5, so as to further enhance the anti-glare purpose, so that the final projected light is softer and more uniform.

[0043] As a further preferred embodiment, the embedded lamp further comprises two mounting springs 6 symmetrically arranged on the outer peripheral wall of the mounting surface ring 7, which are used to fix the embedded lamp on the indoor ceiling by fasteners or direct clamping, and have wide adaptability and convenient installation. Specifically, the mounting springs 6 are detachably connected by plugging, so that different springs can be replaced for installation according to the size of the mounting hole.

[0044] As a further preferred embodiment, at least one "L"-shaped slot 33 is provided on the outer wall of the lamp body fixing ring 3, and the upper end of the slot 33 extends upward to the upper edge of the lamp body fixing ring 3. The inner wall of the heat sink 1 has buckles that are equal in number and opposite in position to the slot 33 structure. In specific applications, the heat sink 1 can be connected from top to bottom by fitting the corresponding buckles and slots 33 and rotating them at a certain angle.

At the same time, since the lamp body fixing ring 3 can be flipped longitudinally at a certain angle (specifically a maximum of 20 degrees) relative to the rotating ring 4, and its position is limited by the locking structure 34, the dimming operation can be performed through the rotating structure, and the light output angle can be adjusted conveniently and reliably.
