At present, the light-emitting angle of most of existing ceiling spot lamps in the market can be only adjusted in a single direction or in two directions due to structural limitation, so that the adjustment requirement of a user on the light-emitting angle is limited.

For this reason, the prior art has proposed a universal down lamp (chinese patent application No. 202020102086. X) comprising: the lamp body rotating assembly comprises a light source and a rotating ring, the light source is fixedly connected with the rotating ring, and the rotating ring is provided with an outer spherical cambered surface; the lamp holder assembly comprises a lamp holder and a pressing ring, and the pressing ring is movably connected with the lamp holder through a connecting piece; the compression ring is provided with an installation through hole; the connecting piece comprises a connecting rod and an abutting part fixedly arranged at one end of the connecting rod, the connecting rod is fixedly connected with the lamp holder through the mounting through hole, and an elastic resetting piece for driving the compression ring to reset is arranged between the abutting part and the compression ring; the lamp holder is provided with an inner spherical cambered surface matched with the outer spherical cambered surface, and the lamp body rotating component is rotatably arranged on the lamp holder through the rotating ring; and the compression ring is provided with a limiting part for installing, clamping and limiting and rotating limiting the rotating ring.

Referring to fig. 1 to 8, in order to overcome all or at least part of the drawbacks of the prior art in the background art, the present invention provides a universal adjustable lighting device, which includes: the light source module comprises a pressing piece 1, a rotating piece 2, a light source module 3, a lamp holder 4 and a back cover 5, wherein the pressing piece 1 is connected in the light emitting direction of the lamp holder 4 in a matching mode, a clamping ring 11 of the pressing piece 1 and a first inner ring 41 of the lamp holder 4 are combined into a sliding rail, so that the rotating piece 2 is in universal connection with the sliding rail through an adjusting ring 21 of the rotating piece, the rotating piece 2 is limited to be separated from the sliding rail through the pressing piece 1, the rotating piece 2 is further connected with the back cover 5, a bearing unit 22 of the rotating piece 2 and an accommodating unit 51 of the back cover 5 are combined into a light source accommodating cavity to bear the light source module 3, the adjusting ring 21 is in interference fit with the clamping ring 11, and the adjusting ring 21 and the sliding rail are enabled to generate different friction forces at the positions of the first inner ring 41 and the two clamping rings 11 so as to be in stress-concordance with the weight borne by the rotating piece 2.

Specifically, the first inner ring 41 is disposed at a first position of the lamp holder 4, the first connecting unit 42 is disposed at a second position of the lamp holder 4, and the fastening groove 43 is disposed at a third position; a second connecting unit 12 is arranged at a first position of the pressing member 1, a clamping ring 11 is arranged at a second position, the second connecting unit 12 is matched and connected with the first connecting unit 42 to fix the light emitting direction of the lamp holder 4 at the position of the pressing member 1, meanwhile, the clamping ring 11 is at least partially accommodated in a buckling groove 43 and combined with the first inner ring 41 to form a slide rail, and a first buffer area 44 is arranged between the clamping ring 11 and the bottom of the buckling groove 43; .

In addition, the first position of the rotating part 2 is provided with an adjusting ring 21, the second position is provided with a bearing unit 22, the adjusting ring 21 is matched and connected with the slide rail to form universal connection with the lamp holder 4, and the rotating part 2 is limited by the pressing part 1 to be difficult to separate from the slide rail.

On the other hand, the adjusting ring 21 is provided with a locking unit 24 at a first position, the back cover 5 is provided with an accommodating unit 51 at a first position, the abutting unit 54 is provided at a second position, the abutting unit 54 is coupled to the locking unit 24, so that the back cover 5 is abutted to the rotating member 2, the accommodating unit 51 and the bearing unit 22 of the rotating member 2 are combined to form a light source accommodating cavity, and the light source module 3 is arranged in the light source accommodating cavity.

It should be noted that in this embodiment, the opening groove 111 is disposed on the clamping ring 11 to separate the clamping ring 11, so that when the adjusting ring 21 is pressed against the clamping ring 11 by the weight of the light source module 3, the clamping ring 11 is expanded to tighten the adjusting ring 21, the first buffer area 44 can accommodate the expansion of the clamping ring 11 to prevent the structure from being clamped, and the opening groove 111 on the clamping ring 11 can also prevent the ring surface from collapsing to improve the elastic deformation capability, thereby the adjusting ring 21 and the slide rail generate two different frictional forces at the positions of the first inner ring 41 and the clamping ring 11, that is, the frictional force of the clamping ring 11 on the adjusting ring 21 is greater than that of the first inner ring 41.

The purpose of this design is that the back of the rotating member 2 itself bears the weight of the light source module 3 and the back cover 5, and the universal adjustment of the rotating member 2 is to be shifted in the light emitting direction from the lamp holder 4, so that the clamping ring 11 is closer to the light emitting direction of the lamp holder 4 than the first inner ring 41, and after the rotating member 2 is shifted, the friction of the clamping ring 11 is larger, so that the rotating member stops once shifted and is fixed in position without being excessively interfered by the first inner ring 41.

If the friction force of the first inner ring 41 is greater than that of the clamping ring 11, the problem of light weight will occur during shifting, so that the operation feel will be poor and the shifting angle will not be easily controlled, whereas if the friction force of the first inner ring 41 is the same as that of the clamping ring 11, the requirements on the manufacturing and assembling processes will be too high, and the cost will be increased. In practice, on the other hand, since the weight borne by the rotating member 2 mentioned above always presses on the clamping ring 11, the friction of the clamping ring 11 is obviously high, so that the friction of the first inner ring 41 must be increased to achieve equality, but this is easily caused, and a large force is required for adjustment, so that the hand feeling is not good.

In addition, on the other hand, in order to further improve the hand feeling of adjustment and the precision of one-time adjustment, two different friction forces of the slide rail can be in the same stress with the weight borne by the rotating piece 2 in design, so that the hand feeling of heavy head and light foot is avoided.

Specifically, the accepted homography means that the friction with the adjusting ring 21 can be theoretically increased/decreased by adjusting the size of the clamping ring 11 and/or the first inner ring 41, so that the weight of the rotating member 2 can be calculated to form a balance with the friction, thereby avoiding the deviation of the inertial movement due to the self weight when the rotating member 2 is pulled, thereby increasing the accuracy of one-time adjustment and improving the adjustment feel.

In another preferred embodiment, the clamping ring 11 is preferably made of an elastic material, the curvature of the clamping ring 11 is different from the curvature of the first inner ring 41, the adjusting ring 21 is concentric with the center of the first inner ring 41 and has a similar arc radius, so that the adjusting ring 21 is in contact with the contact surface of the first inner ring 41, and the adjusting ring 21 and the clamping ring 11 are in interference fit, that is, the adjusting ring 21 can press the clamping ring 11 by its own weight to make its elastic force return to wrap the adjusting ring 21, so that the adjusting ring 21 and the slide rail generate two different frictional forces at the positions of the first inner ring 41 and the clamping ring 11, that is, the frictional force of the clamping ring 11 on the adjusting ring 21 is greater than that of the first inner ring 41.

Further, in order to design a pressing member 1 capable of conveniently detaching from the light emitting direction of the lamp holder 4, and simultaneously, firmly locking the rotating member 2 without coming off from the slide rail, in a preferred embodiment, the first connecting unit 42 of the lamp holder 4 includes: the fastening table 421, the button 422 extends out from fastening table 421 one side, compress tightly 1 second coupling unit 12 and include: the pressing piece 1 is respectively connected with the fastening table 421 and the fastening head 422 of the lamp holder 4 through the fastening ring 121 and the fastening groove 122, so that the pressing piece 1 is fixed in the light emitting direction of the lamp holder 4, and the clamping ring 11 is also abutted against the adjusting ring 21 to bear the gravity borne by the rotating piece 2, so as to extrude the fastening groove 122 to fasten the fastening head 422, so that the pressing piece 1 is firmly fixed on the lamp holder 4.

Specifically, in order to reduce the number of assembled parts and facilitate the assembly and disassembly, the pressing member 1 adopts a clamping structure in design, so that a margin is required to be reserved in the assembly size, however, the margin can generate a certain gap after the assembly to cause looseness, in the embodiment, the bearing of the rotating member 2 is skillfully utilized, so that when the pressing member 1 is installed, the pressing member can be easily buckled into the lamp holder 4, then, the weight of the rotating member 2 naturally falls onto the body of the pressing member 1, and at the moment, through the ingenious structural design, the buckling head 422 can be buckled through the buckling groove 122, so that the pressing member 1 is ensured not to fall off and not to generate looseness. When the disassembly is needed, the pressing piece 1 can be easily disassembled only by slightly lifting the rotating piece 2 by using the hand to directly lift the rotating piece, so that the subsequent disassembly is convenient.

Further, in order to improve the reliability of the fit between the adjusting ring 21 and the clamping ring 11 and at the same time improve the maximum adjustable angle of the rotating member 2, in a preferred embodiment, a second buffer area 45 is provided between the adjusting ring 21 and the bearing unit 22, the second buffer area 45 is provided at the second position of the adjusting ring 21, and the buffer area can provide a fit elastic margin when the adjusting ring 21 is fit with the clamping ring 11, and the buffer area is set up to reduce the vibration of friction when the adjusting ring 21 is friction with the clamping ring 11, so as to improve the smooth hand feeling during the adjustment.

In addition, as shown in fig. 8, the radius of the bearing unit 22 and the back cover 5 of the rotating member 2 is smaller than the radius of the sliding rail, so that the maximum adjustable angle of the rotating member 2 can be improved, and the adaptability of the scene can be improved.

As shown in fig. 5, in the present embodiment, the light source module 3 includes: the optical lens 31, the LED light source module 32, wherein for better fixing the light source module 3 in the light source accommodating cavity, the bearing unit 22 of the rotating member 2 is provided with a first fastening portion 23 for fastening and fixing the optical lens 31, and the accommodating unit 51 of the back cover 5 is provided with a second fastening portion 52 for fastening and fixing the LED light source module 32, thereby fixing the positions of the optical lens 31 and the LED light source module 32 in the light source accommodating cavity to form a preset light emitting effect, and in addition, the LED light source module 32 can be electrically connected with an external power supply through the wiring port 53 of the back cover 5.
