In the description of the present invention, "a plurality" means two or more unless specifically limited otherwise.

the following describes the implementation of the present invention in detail with reference to specific embodiments.

As shown in fig. 1 and fig. 3-4, an embodiment of the present invention provides a down lamp, which includes a lamp body 1, a surface ring 3 connected to the lamp body 1, a lifting adjusting mechanism 2 connected to the lamp body 1, and a light emitting assembly 4 located in the surface ring 3; the lifting adjusting mechanism 2 comprises a lifting bracket 21 connected with the lamp body 1 and a lifting sliding plate 22 arranged on the lifting bracket 21 in a sliding way; the lifting sliding plate 22 can slide along the axial direction of the surface ring 3 relative to the lifting support 21, a deflection shaft is arranged between the light emitting component 4 and the lifting sliding plate 22, and the light emitting component 4 is rotatably connected with the lifting sliding plate 22 through the deflection shaft.

In the embodiment of the present invention, the surface ring 3 is an annular structure, and is disposed around the light emitting element 4; when the light-emitting angle of the light-emitting component 4 needs to be adjusted during use, applying deflection force to the light-emitting component 4 to enable the light-emitting component 4 to deflect towards two sides along the relative lifting sliding plate 22 of the deflection shaft, so as to change the light-emitting angle, when the deflection angle of the light-emitting component 4 is large enough, the surface ring 3 shields the part or all light rays of the light-emitting component 4, applying enough tension to the lifting sliding plate 22 to enable the lifting sliding plate 22 to slide along the axis direction of the surface ring 3 relative to the lifting support 21 (namely to move downwards along the vertical direction), making the distance of the light-emitting component 4 extending out of the surface ring 3 large enough, and the surface ring 3 does not shield the light rays of the light-emitting component 4. As shown in fig. 2 to fig. 3, the light emitting element 4 may also extend out of the surface ring 3, and then a deflection force is applied to the light emitting element 4 to deflect the light emitting element 4 to two sides along a deflection axis relative to the lifting slide plate 22, so as to change the light emitting angle.

it can be understood that when the light-emitting module 4 is rotatably connected to the lifting slide 22 through the deflection shaft, a certain friction force exists between the light-emitting module 4 and the lifting slide 22, and it is only necessary to apply a proper external deflection force to rotate the light-emitting module 4 relative to the lifting slide 22.

It can be understood that, the friction force between the lifting slide plate 22 slidably mounted on the lifting support 21 and the lifting support 21 is sufficient, and the friction force is larger than the gravity force of the light-emitting assembly 4 and the lifting slide plate 22, so that the lifting slide plate 22 can slide (i.e. move up and down in the vertical direction) along the axial direction of the surface ring 3 relative to the lifting support 21 only when a user applies a pulling force or a pushing force to the lifting slide plate 22. The friction force between the lifting slide plate 22 and the lifting support 21 can be the friction force generated by the direct contact between the lifting slide plate 22 and the lifting support 21; friction may also be created by indirect contact of the lift slide 22 with the lift bracket 21, such as by applying a transition member between the lift slide 22 and the lift bracket 21.

The lifting pre-tightening component 23 is the transition component, and the lifting pre-tightening component 23 is arranged between the lifting sliding plate 22 and the lifting support 21, so that the pre-tightening force of the lifting pre-tightening component 23 is set to be large enough, so that the gravity of the light emitting component 4 and the lifting sliding plate 22 is smaller than the friction force provided between the lifting sliding plate 22 and the lifting support 21, and the lifting sliding plate 22 and the lifting sliding plate 4 can be ensured not to slide relative to the lifting support 21 under the condition of not receiving external force, so that the light emitting component 4 is kept unchanged at a certain height, and when a user applies pulling force or pushing force, the lifting sliding plate 22 moves relative to the lifting support 21 along the vertical direction, so that the distance of the light emitting component 4 extending out of the face ring 3 is changed. Specifically, the lifting slider 22 is slidably connected to the lifting bracket 21 through the lifting connection member 231 connected thereto, and the elastic member 232 applies an elastic pre-tightening force between the lifting connection member 231 and the lifting bracket 21, so that an indirect friction force is generated between the lifting slider 22 connected to the lifting connection member 231 and the lifting bracket 21, and no relative sliding occurs without external force.
