Referring to fig. 1 and 2, the utility model provides a down lamp convenient to dismouting. The down lamp includes a heat sink 100, a bottom chassis 200, and a face ring 300; the bottom chassis 200 and the heat sink 100 are combined to form an accommodating cavity, a controller 430, an inductor 410 and a lamp body 420 are arranged in the accommodating cavity, and the lamp body 420 and the inductor 410 are electrically connected with the controller 430; the sensor 410 protrudes from the bottom case 200; at least one elastic arm 210 is arranged on the outer side surface of the bottom shell 200, and the surface ring 300 is provided with an inductor through hole 310; the surface ring 300 is sleeved outside the bottom case 200, and the inductor 410 passes through the inductor through hole 310; under the action of the at least one elastic arm 210, the face ring 300 is abutted against and fixed with the bottom case 200.

In this embodiment, when the face ring 300 is mounted on the bottom chassis 200, the sensor through hole 310 of the face ring 300 is aligned with the sensor 410, and then the face ring 300 is fitted on the outer side of the bottom chassis 200, the face ring 300 presses the elastic arm 210 toward the bottom chassis 200, and the face ring 300 presses toward the bottom chassis 200 until the sensor 410 completely passes through the sensor through hole 310. The resilient arms 210 have a tendency to extend outward to return toward the face ring 300. Under the action of the elastic arms 210, the face ring 300 is abutted against and fixed to the bottom case 200. When the cover is removed, the cover ring 300 is pulled out in a direction away from the bottom case 200.

Through the installation mode, the face ring 300 can be directly sleeved on the bottom shell 200 to be fixed, the face ring 300 collides with the convex inductor 410 without rotating or deviating the face ring 300, the inductor through hole 310 is not easy to deviate from the position of the inductor 410, and the convenience in dismounting the face ring 300 is improved.

In addition, the receiving cavity formed by combining the heat sink 100 and the bottom chassis 200 plays a role of protecting the controller 430, the inductor 410, and the lamp body 420 inside. Sensor 410 may be any sensor capable of sensing sound, light, or heat.

Further, the face ring 300 includes a side ring wall 341 and a bottom ring 342, and the side ring wall 341 is disposed at an outer edge of the bottom ring 342. When the face ring 300 is fitted over the outer side of the bottom chassis 200, the side ring walls 341 protect the sides of the bottom chassis 200, and the bottom ring 342 protects the bottom surface of the bottom chassis 200. The inductor 410 protrudes from the bottom surface of the bottom chassis 200, and the inductor through-hole 310 is correspondingly positioned on the bottom ring 342. In addition, spring ears for hanging the down lamp on the ceiling can be arranged on two sides of the face ring 300.

Further, the bottom ring 342 is provided with a light through hole 320; when the surface ring 300 is sleeved on the outer side of the bottom chassis 200, the light through hole 320 faces the lamp body 420. The lamp body 420 emits light through the lamp hole 320 to be irradiated downward.

It should be noted that the light through holes 320 may be different in shape; such as square, circular or oval.

Further, the outer side of the bottom case 200 is provided with a positioning groove 332 extending upward from the bottom surface, and the inner side of the side annular wall 341 is provided with a positioning protrusion 331 matching with the positioning groove 332; when the face ring 300 is sleeved outside the bottom case 200, the positioning protrusion 331 is inserted into the positioning groove 332. Specifically, there are two positioning grooves 332 and two positioning protrusions 331; the two positioning grooves 332 are symmetrically arranged on the outer side surface of the bottom case 200; two positioning protrusions 331 are symmetrically disposed on the inner side surface of the side circumferential wall 341. Through the cooperation of the positioning protrusion 331 and the positioning groove 332, the face ring 300 is positioned better, and the sensor through hole 310 and the sensor 410 are prevented from colliding and damaging the sensor 410 due to the rotational deviation of the face ring 300 sleeved on the bottom case 200.

Further, the inductor 410 is installed on the arc-shaped fixing plate 411, and the screw fastener penetrates through the fixing plate 411 and the bottom case 200 to fix the two. The inductor 410 is mounted on the bottom chassis 200 through the fixing plate 411.

Further, at least one recessed insert 220 is disposed on an outer side surface of the bottom chassis 200, and the elastic arms 210 are disposed on the recessed inserts 220 in a one-to-one correspondence; the ends of the elastic arms 210 protrude out of the outer side of the bottom case 200. Specifically, there are three recessed inserts 220 and three elastic arms 210 uniformly surrounding the outer side of the bottom case 200, so as to improve the fixing effect of the top ring 300 and the bottom case 200. In addition, the elastic arm 210 includes an arm 211 and a protrusion 212, the arm 211 is connected to the bottom case 200, and the protrusion 212 is located at the end of the arm 211 and protrudes out of the outer side of the bottom case 200. In addition, the outer side surface of the arm 211 is flush with the outer side surface of the bottom case 200. The projection 212 is provided with a guide surface to facilitate insertion of the projection 212 into the face ring 300.

In this embodiment, when the face ring 300 is sleeved outside the bottom case 200, the face ring 300 abuts against the protrusion 212 and presses the elastic arm 210 toward the female fitting 220 by the elastic action of the arm 211. When the face ring 300 is separated from the bottom case 200, the face ring 300 no longer abuts against the elastic arms 210, and the elastic arms 210 are reset under the elastic action of the arm levers 211.

Further, the heat sink 100 is connected to the bottom chassis 200 by screws 230; the screw 230 is located in the recessed portion 220 and inside the elastic arm 210. The screw 230 is mounted on the top surface of the female socket 220. The screw 230 is hidden and does not protrude from the bottom case 200, and does not collide and rub with the face ring 300 and the housing.

The above description is only a preferred embodiment of the present invention, and the present invention is not limited to the above embodiment, and the technical effects of the present invention can be achieved by the same means, which all belong to the protection scope of the present invention.
