As shown in fig. 5 and 6, the lamp body 5 includes a lamp cap 51 and a heat sink 52, the lamp cap 51 has a module structure, and a light source assembly and a power source assembly (not shown) are installed inside the lamp cap 51; the heat sink 52 has a fin structure disposed above the lamp cap 51 for dissipating heat generated from the components of the lamp cap 51. The overall size of the heat sink 52 is larger than that of the base 51, i.e., the heat sink 52 extends upward from the upper side of the base 51.
Referring to fig. 3 and 5 in combination, when the lamp body 5 is erected above the front ring 1, the heat dissipation member 52 is supported on the upper edge of the front ring 1, and the lamp cap 51 is located in the cavity of the front ring 1. At this time, the light shield 2 is not rotated, the elastic member 32 of the pressing assembly 3 is in a relaxed and uncompressed state, and the baffle 21 of the light shield 2 laterally covers the notch 41 of the light reflecting cup 4, so as to avoid light leakage caused by overflow of light emitted from the lamp body 5 from the notch 41.
Referring to fig. 4 and 6 in combination, the lamp body 5 vertically rotates relative to the front ring 1, and after the lamp cap 51 rotates in the cavity by a certain angle, the lower outer edge of the heat dissipation member 52 presses the upper end of the pressing post 33, and the convex post 34 of the pressing post 33 is cooperatively connected with the arc-shaped groove 22 of the light shield 2. At this time, the elastic member 32 is in a compressed state, the light shield 2 is horizontally rotated by a certain angle under the driving of the pressing post 33, the baffle 21 at the inner side of the light shield 2 is moved away from the notch 41 of the light reflecting cup 4, and at this time, the notch 41 forms a rotation position 42 required for rotation of the lamp body 5, so that the lamp cap 52 of the lamp body 5 enters the cavity of the front ring 1.

Therefore, in the adjustable ceiling lamp of the embodiment, when the lamp body is used for direct illumination, the baffle plate of the light shield covers the notch of the reflecting cup from the side surface so as to prevent light leakage and improve the luminous efficiency; when the lamp body vertically rotates by a certain angle, the lamp body drives the light shield to horizontally rotate in the cavity of the front ring through the pressing component, so that a rotation position required by rotation of the lamp body is emptied in the cavity, and the lamp body can conveniently rotate by a larger adjusting angle.
The adjustable ceiling lamp of this embodiment carries out the angle modulation through the cooperation of lamp body and preceding ring. Specifically, as shown in fig. 7, the front ring 1 forms a thickened inner edge at the top, and an arc-shaped rotating base 11 is provided at the top, the rotating base 11 is provided along the annular front ring top and does not completely cover the top, an arc-shaped notch 12 is also formed at the remaining part of the front ring top, and the lamp body 5 rotates between the rotating base 11 and the notch 12.
The sliding block 111 is formed at the end of the rotating base 11, and the sliding block 111 is not completely connected with the main body of the rotating base 11 in an arc shape, but is slightly bent and recessed toward the inner center of the front ring 1, so that a gap 120 is left at the top of the front ring 1, and the gap 120 is beneficial to smooth rotation of the lamp body 5 during angle adjustment.
It should be noted that, two groove bodies, namely a first chute 112 and a second chute 113, are provided at the sliding block 111, and the first chute 112 is horizontally arranged, i.e. parallel to the top surface of the front ring 1; the second sliding groove 113 is arranged obliquely downwards, and the second sliding groove 113 is adjacent to the first sliding groove 112. Specifically, the upper end of the second chute 113 is adjacent to one of the horizontal ends of the first chute 112. In some embodiments, the first runner 112 has a racetrack-shaped configuration and the second runner 113 has an oval-shaped configuration.
The sliding block 111 is also provided with a downward-inclined rail 114 above, the rail 114 is located at the end of the rotating base 11 and above the second chute 113, and the rail 114 is used for rotating in cooperation with the lamp body 5.
In the lamp body 5, a base 51 located below the lamp body is provided with rotating arms 53 on the outside, and centers of the two rotating arms 53 are located on the same diameter of the base 51. The rotating arm 53 is provided with a first link 531 and a second link 532 protruding outward. The first link 531 of the present embodiment is located at the center of the rotating arm 53, and the second link 532 is protruded from the side wall of the rotating arm 53.
Fig. 8 is a sectional view of the lamp body of the present embodiment and the front ring when standing upright, fig. 9 is a sectional view of the lamp body of the present embodiment and the front ring when rotating, and referring to fig. 8 and 9 in combination, in the connection structure of the lamp body and the front ring, the first connecting rod 531 penetrates the first chute 112 and is connected with the first chute 112 in a matching manner, and the second connecting rod 532 penetrates the second chute 113 and is connected with the second chute 113 in a matching manner. At this time, the first link 531 forms an offset axis of the adjustable ceiling lamp, and the second link 532 forms a stress axis of the adjustable ceiling lamp.
As shown in fig. 8, when the lamp body 5 stands upright with respect to the front ring 1, the first link 531 is positioned at the left end of the first chute 112, and the second link 532 is positioned at the upper end of the second chute 113. In some embodiments, when the lamp body 5 is upright, the outer edge of the heat dissipation element 52 is supported on the rotating base 51; of course, in other embodiments, the heat sink 52 may not contact the rotating base 51.
When the base 51 of the lamp body 5 rotates in the cavity 10 of the front ring 1, the second link 532 as a force-receiving shaft is caused to generate a lateral force in the second slide groove 113, and the first link 531 as an offset shaft is caused to displace and rotate along the first slide groove 112. Meanwhile, the first chute 112 has a certain limiting effect on the first connecting rod 531, and after the angle adjustment is completed, the lamp body and the front ring can keep fixed positions. As shown in fig. 9, after the rotation adjustment is completed, the first link 531 is located at the right end of the first slide groove 112, and the second link 532 is located at the lower end of the second slide groove 113. At this time, through carrying out optimal design to the reflector cup, the light that lamp holder 5 sent can all get into reflector cup 4, and the reflection processing back that goes out through reflector cup 4 is gone out, guarantees out luminous efficacy.
In the adjustable ceiling lamp provided by the embodiment, the first connecting rod and the second connecting rod of the lamp body are respectively connected with the first chute and the second chute of the front ring in a matched manner, and the first connecting rod and the second connecting rod respectively form an offset shaft and a stress shaft, so that when the lamp body rotates, the second connecting rod of the stress shaft generates lateral force, and the first connecting rod of the offset shaft is displaced and rotated; meanwhile, the damping piece enables the first sliding groove to have a limiting effect on the first connecting rod, after angle adjustment is completed, the position of the lamp body and the position of the front ring are fixed, and light rays emitted by the lamp body can fall into the reflecting cup completely and exit after being reflected by the reflecting cup, so that the luminous efficacy is ensured.

This allows stepless adjustment of the rotation of the lamp relative to the front ring, and further allows for a limited fixing of the positions of the rotating arm 53 and the rotating base 11 after the adjustment is completed.
Because the rotating base 11 is provided with the inclined downward track 114 at the sliding block 111, the lamp body 5 can be attached to the front ring 1 for rotation, and light can freely exit through the cavity 11 without being blocked, so that the light-emitting efficiency can be effectively improved.
