Description

Technical Field

[0001] The utility model relates to the field of lamp design, in particular to a focus-adjustable spotlight structure. Background Art

[0002] Spotlights are a common type of lamps. They can be placed on the ceiling, walls, or furniture. They are suitable for use as main lighting as well as auxiliary light sources. They have a wide range of application scenarios and are highly practical.

[0003] The effective lighting distance of existing spotlights is usually determined by their focal length. Generally speaking, the larger the focal length, the smaller the lighting range and the higher the brightness, and vice versa. The focal length of existing spotlights is usually fixed after production, and users cannot adjust it. As the application scenarios of spotlights become more and more extensive, people sometimes want to adjust the lighting range of spotlights during actual use, that is, to adjust the focal length of spotlights. However, this can often only be achieved by directly replacing the spotlights, which is very inconvenient. Utility Model Content

[0004] The purpose of the utility model is to provide a spotlight structure with adjustable focal length, which can solve one or more of the above problems.

[0005] According to one aspect of the utility model, there is provided a spotlight structure with adjustable focal length, comprising a lamp body structure, a fixed lamp head, a lens structure, a screw, a rotating ring and a face ring, wherein the fixed lamp head is connected to the lamp body structure, the fixed lamp head is provided with a central groove and a side groove, the side groove is provided with a spiral groove, the rotating ring is rotatably mounted on the side groove, the rotating ring is provided with a vertical groove, the lens structure is located in the central groove, the screw is connected to the lens structure, one end of the screw passes through the spiral groove and extends into the vertical groove, and the face ring is mounted on the rotating ring.

[0006] The beneficial effect of the utility model is that in the utility model, the user can rotate the face ring so that the rotating ring can rotate together. During the rotation of the rotating ring, the screw can be driven by it to move together. Then, under the limit of the rotating ring and the fixed lamp head, the screw can move along the spiral groove and the vertical groove at the same time, thereby realizing the up and down movement of the screw, that is, realizing the up and down movement of the lens structure, that is, effectively adjusting the focal length of the utility model. Therefore, the utility model can adjust the focal length through simple operation, thereby effectively adjusting the lighting effect of the lamp body structure.

[0007] In some embodiments, the lamp body structure includes a light source, a lamp body base, a universal head and a lamp holder seat, the universal head is connected to the lamp body base, the lamp holder seat is connected to the universal head, and the light source is mounted on the lamp holder seat.

DETAILED DESCRIPTION

[0021] The utility model is further described in detail below in conjunction with the accompanying drawings.

[0022] refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 7 The utility model discloses an adjustable focus spotlight structure, comprising a lamp body structure 1, a fixed lamp holder 2, a lens structure 3, a screw 4, a rotating ring 5 and a face ring 6.

[0023] The lamp body structure 1 includes a light source 11, a lamp body base 12, a universal head 13 and a lamp holder 14. The universal head 13 is connected to the lamp body base 12 via a pin, and the lamp holder 14 is fixedly connected to the universal head 13 via bolts. The light source 11 can preferably be an LED light source, and the light source 11 is fixedly mounted on the lamp holder 14 via bolts.

[0024] A accommodating cavity 21 is provided in the fixed lamp holder 2, an internal thread 211 is provided in the accommodating cavity 21, an external thread 141 is provided on the lamp holder base 14, the light source 11 is located in the accommodating cavity 21, the internal thread 211 and the external thread 141 are connected by threaded matching, so that the fixed lamp holder 2 is fixedly connected to the lamp body structure 1.

[0025] A central groove 22 is provided in the middle of the fixed lamp holder 2 , a side groove 23 is provided on the side of the fixed lamp holder 2 , and a spiral groove 231 is provided on the side groove 23 .

[0026] The rotating ring 5 is sleeved on the side groove 23, and the rotating ring 5 can rotate on the side groove 23. The rotating ring 5 is provided with a vertical groove 51, and the side groove 23 is also provided with an annular rack 232. A center hole 52 is provided in the middle of the rotating ring 5, and a recess 521 and a tooth block 522 are provided on the side wall of the center hole 52. When the rotating ring 5 is sleeved on the side groove 23, the annular rack 232 will extend into the recess 521, and the tooth block 522 and the annular rack 232 will mesh.

[0027] The lens structure 3 comprises a lens 31 and a lens seat 32. The lens 31 is fixedly mounted on the lens seat 32 by snapping, and the screw 4 is fixedly connected to the side of the lens seat 32 by threaded engagement.

[0028] The lens seat 32 is located in the center groove 22 , and the lens seat 32 can move to a certain extent in the center groove 22 , and can rotate or move up and down in the center groove 22 . After the lens seat 32 is set, one end of the screw 4 passes through the spiral groove 231 and extends into the vertical groove 51 of the rotating ring 5 .

[0029] A slot 61 is provided in the face ring 6, and a block 53 is provided on the outer side of the rotating ring 5. The block 53 is stuck in the slot 61, so that the face ring 6 is fixedly mounted on the rotating ring 5, and the face ring 6 after being set can cover the side groove 23 and the rotating ring 5, so that the side groove 23 and the rotating ring 5 are not exposed.

[0030] When the utility model is in use, the lamp base 12 can be connected to a fixed structure such as a wall or a ceiling by bolts, and the light source 11 can be connected to an external power supply circuit by a wire, and the light emitted by the light source 11 can be emitted to the outside through the lens 31.

[0031] When the user needs to adjust the lighting range of the utility model, that is, adjust the focal length of the utility model, the user can rotate the face ring 6, and the rotating ring 5 connected to the face ring 6 can also rotate accordingly. At this time, a screw 4 with a section extending into the vertical groove 51 of the rotating ring 5 can also rotate accordingly under the drive of the rotating ring 5, and because the screw 4 passes through the spiral groove 231, the screw 4 can move along the spiral groove 231 when rotating, and the screw 4 extends into the vertical groove 51, and the screw 4 can also move along the vertical groove 51. Under the common limitation of the spiral groove 231 and the vertical groove 51, the screw 4 can move up and down accordingly during the rotation process, and the lens structure 3 connected to the screw 4 can also move up and down accordingly, thereby changing the distance between the lens 31 and the light source 11, to effectively change the focal length of the utility model.

[0032] In addition, during the rotation of the rotating ring 5, since the tooth block 522 and the annular rack 232 are meshed, the tooth block 522 can move accordingly on the annular rack 232. When the position adjustment of the rotating ring 5 is completed, that is, the user no longer rotates the face ring 6, the rotating ring 5 is no longer subjected to force. At this time, relying on the meshing of the tooth block 522 and the annular rack 232, the rotating ring 5 can stay in the current position, that is, effectively maintain the current focal length of the utility model.

[0033] The above are only some embodiments of the present invention. For those skilled in the art, several modifications and improvements can be made without departing from the inventive concept of the present invention, which all belong to the protection scope of the present invention.
