[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Example: Figure 1-8 As shown, the replaceable recessed lamp includes a lamp body 1 and a face ring 2. The face ring 2 is detachably fixed to the lamp body 1. The face ring 2 and the lamp body 1 can rotate relative to each other. The lamp body 1 is provided with a screwing groove 101, and the face ring 2 is provided with a screwing block 201. The screwing groove 101 extends circumferentially around the lamp body 1 and has a screwing inlet 102 for the screwing block 201 to move into or out of the screwing groove 101. When the face ring 2 and the lamp body 1 rotate relative to each other, the screwing block 201 moves along the screwing groove 101 and abuts against the screwing groove 101 axially to restrict the face ring 2 from disengaging from the lamp body 1. The wall of the screwing groove 101 is provided with a stop block 103 that abuts against the screwing block 201 circumferentially to restrict the screwing block 201 from moving away from the screwing groove 101. During assembly, firstly, the face ring 2 is fixed to the ceiling. The screwing block 201 moves from the screw inlet 102 into the screwing groove 101. Then, the lamp body 1 is rotated so that the screwing block 201 moves along the screwing groove 101 to the side of the stop block 103 opposite to the screw inlet 102. Since the screwing block 201 abuts axially with the screwing groove 101 and circumferentially with the stop block 103, when the screwing block 201 moves to the side of the stop block 103 opposite to the screw inlet 102, the screwing block 201 is confined within the screwing groove 101, making the face ring 2 and the lamp body 1 stably assembled and not easily detached.

[0028] In summary, this embodiment provides a replaceable embedded lamp to solve the problem that the lamp body and face ring of existing spotlights are connected by a snap-fit ​​structure or a ball bearing structure, resulting in unstable assembly of the face ring and easy detachment. The main solution is to configure a screw groove 101 on the lamp body 1, a screw block 201 on the face ring 2, and a stop block 103 in the screw groove 101. When the screw block 201 is screwed into the screw groove 101 and moves to the side of the stop block 103 opposite to the screw inlet 102, the screw block 201 is restricted within the screw groove 101, making the face ring 2 and the lamp body 1 stably assembled and less prone to detachment.

[0029] Because the face ring 2 is detachably connected to the lamp body 1, the same face ring 2 can be combined with different lamp bodies 1, resulting in good compatibility.

[0030] In other embodiments, the lamp body 1 is provided with a screwing block 201 and the face ring 2 is provided with a screwing groove 101.

[0031] In this embodiment of the utility model, there are several screw blocks 201 and screw grooves 101, each corresponding to one another. The screw grooves 101 are spaced apart around the lamp body 1, and at least two screw grooves 101 are arranged opposite each other. By configuring several screw blocks 201 and screw grooves 101 in a corresponding manner, and at least two screw grooves 101 being arranged opposite each other, when the screw block 201 is screwed into the screw groove 101 and moved to the side of the stop block 103 opposite to the screw inlet 102, the face ring 2 is stably assembled with the lamp body 1, and the face ring 2 is not easily dislodged when the lamp body 1 shakes.

[0032] In this embodiment of the invention, the lamp body 1 has a screwing portion 104 protruding from its outer surface. The screwing portion 104 extends circumferentially around the lamp body 1 and is provided with a screwing groove 101. A screwing block 201 is provided on the inner side of the face ring 2. By configuring the lamp body 1 with a screwing portion 104 protruding from its outer surface and with the screwing groove 101 formed on the screwing portion 104, the lamp body 1 has good structural strength and is not easily deformed.

[0033] In this embodiment of the invention, the axial direction of the lamp body 1 is positioned in the up-down direction, and a screw inlet 102 is provided at the top of the screwing part 104. The above arrangement, by placing the screw inlet 102 at the top of the screwing part 104, facilitates the screwing block 201 to be screwed into the screwing groove 101.

[0034] In this embodiment of the invention, the screwing part 104 is provided with upper guide slopes 105 on opposite sides of the screwing inlet 102, and each upper guide slope 105 extends obliquely from bottom to top in a direction away from the screwing inlet 102. The above arrangement, by providing upper guide slopes 105 on opposite sides of the screwing inlet 102, facilitates the screwing block 201 to be screwed into the screwing groove 101.

[0035] In this embodiment of the invention, a lower guide slope 106 is formed on the side of the stop block 103 adjacent to the screw inlet 102, and the lower guide slope 106 extends obliquely from top to bottom in a direction away from the screw inlet 102. This arrangement, by configuring the lower guide slope 106 on the side of the stop block 103 adjacent to the screw inlet 102, facilitates the screwing block 201 to be screwed to the side of the stop block 103 opposite to the screw inlet 102.

[0036] In this embodiment of the invention, the side of the stop block 103 facing away from the rotary inlet 102 is a vertically extending plane. By configuring the side of the stop block 103 facing away from the rotary inlet 102 as a vertically extending plane, the stop block 103 has a good limiting effect, restricting the screwing block 201 from moving away from the screwing groove 101.

[0037] In this embodiment of the invention, the face ring 2 has an upward-opening positioning groove 202, and the screwing block 201 is located directly below the positioning groove 202. This arrangement, by configuring the upward-opening positioning groove 202 on the face ring 2 and placing it directly above the screwing block 201, facilitates the user's observation of the position of the screwing block 201.

[0038] In this embodiment of the invention, the stop block 103 extends downward on the side of the spin inlet 102. By configuring the stop block 103 so that the side of the spin inlet 102 extends downward, the user can quickly rotate the screw block 201 to the side of the stop block 103 that is opposite to the spin inlet 102.

[0039] In this embodiment of the utility model, the lamp body 1 includes a lamp housing 107, a light source 108 and a light cup 109. The lamp housing 107 has an assembly cavity 110 with an opening facing downward. The light cup 109 and the light source 108 are housed in the assembly cavity 110 and arranged sequentially from bottom to top. The face ring 2 is arranged around the lower end side wall of the lamp housing 107.
