When the face ring 1 is inserted into the housing 4 from top to bottom to make the positioning block 402 be clamped into the first positioning slot 101, the first assembly hole 108 is opposite to the second assembly hole 407. The present embodiment provides an embedded down lamp to solve the problem that the existing down lamp lacks a circumferential positioning structure between a housing and a surface ring, and when in installation, the housing and the surface ring rotate relatively in the circumferential direction to cause the dislocation of hole sites on the two, so that the assembly of an elastic sheet and the surface ring and the housing is difficult, mainly by configuring a positioning block 402 extending up and down on the inner wall of the housing 4 and configuring a first positioning slot 101 on the surface ring 1, which is in clamping fit with the positioning block 402, to limit the rotation of the surface ring 1 relative to the housing 4, so that when the surface ring 1 is inserted into the housing 4 from top to bottom, the accurate alignment (the dislocation of hole sites) of the first assembly hole 108 and the second assembly hole 407 is realized, and the assembly of the elastic sheet 2 and the surface ring 1 and the housing 4 is accurate and convenient. Since the adjusting hole 104 is provided beside the first positioning groove 101 in the face ring 1, and an adjusting rod capable of moving along the adjusting hole 104 to push against the inner wall of the housing 4 is provided in the adjusting hole, when the face ring 1 and the housing 4 are assembled to loose (shake) or incline, the adjusting rod can push against the inner wall of the housing 4 to realize reinforcement or adjustment balance.

In the embodiment of the utility model, the face ring 1 is provided with an upper circular ring 102 abutting against the opening of the shell 4 and a lower circular ring 103 extending into the shell 4 from the upper circular ring 102, the lower circular ring 103 is provided with a first positioning groove 101 and is provided with an adjusting hole 104 beside the first positioning groove 101, and an adjusting rod capable of moving along the adjusting hole 104 to abut against the inner wall of the shell 4 is arranged in the adjusting hole.

In the embodiment of the present utility model, the lower ring 103 is provided with a limiting rib 105 extending downward on two opposite sides of the first positioning groove 101 in the circumferential direction of the face ring 1, and an adjusting hole 104 is provided on any one of the limiting ribs 105. Because the lower circular ring 103 is provided with the limiting ribs 105 extending downwards on two opposite sides of the first positioning groove 101 in the circumferential direction of the face ring 1, the groove length of the first positioning groove 101 is prolonged, the contact area between the first positioning groove 101 and the positioning block 402 is increased, and the limiting stability is improved.

In the embodiment of the utility model, the number of the first positioning grooves 101 is a plurality, the first positioning grooves 101 are centrally symmetrical with respect to the axis of the face ring 1, the number of the positioning blocks 402 is a plurality, and the positioning blocks 402 are in one-to-one correspondence with the first positioning grooves 101. Because the number of the first positioning grooves 101 is a plurality, the number of the positioning blocks 402 is a plurality, and the plurality of positioning blocks 402 are in one-to-one correspondence with the plurality of first positioning grooves 101, the circumferential limiting stability is good.

In the embodiment of the present utility model, two opposite sides of the positioning block 402 in the circumferential direction of the face ring 1 respectively abut against two opposite groove walls of the first positioning groove 101 in the circumferential direction of the face ring 1. Since the two opposite sides of the positioning block 402 in the circumferential direction of the face ring 1 respectively abut against the two opposite groove walls of the first positioning groove 101 in the circumferential direction of the face ring 1, the rotation range of the face ring 1 relative to the housing 4 is minimized, and the circumferential limit stability is high.

In the embodiment of the utility model, the reflector further comprises a reflector cup 5, a clamping groove 403 is formed in one side, opposite to the inner wall of the shell 4, of the positioning block 402, the clamping groove 403 extends in the circumferential direction of the shell 4, and the reflector cup 5 extends into the shell 4 from the face ring 1 and is provided with a buckle 501 in clamping fit with the clamping groove 403. Because the locating block 402 is provided with the clamping groove 403 on the side opposite to the inner wall of the casing 4, the reflecting cup 5 is provided with the clamping buckle 501 matched with the clamping groove 403 in a clamping way, and therefore the connection structure of the down lamp is compact and reasonable.

In the embodiment of the utility model, a second positioning groove 404 extending up and down is arranged at one side of the positioning block 402 opposite to the inner wall of the casing 4, the reflective cup 5 is provided with a positioning bar 502 which is in clamping fit with the second positioning groove 404 to limit the rotation of the reflective cup 5, and a buckle 501 is arranged on the positioning bar 502.
