When it is necessary to change the beam angle, it is often necessary to manually disassemble the spotlight, adjust its physical position, and then reassemble it. This process is cumbersome and can easily damage the decorative layout. Utility Model Content

[0029] This invention provides the following description with reference to the accompanying drawings to aid in a comprehensive understanding of the various embodiments of the invention as defined by the claims and their equivalents. The description includes various specific details to aid understanding, but these details should be considered exemplary only. Therefore, those skilled in the art will recognize that various changes and modifications can be made to the various embodiments described herein without departing from the scope and spirit of the invention.

[0030] In the description of this utility model, the orientation descriptions, such as up, down, front, back, left, right, etc., are based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0031] It should be understood that when one element (e.g., the first element) is “connected” to another element (e.g., the second element), the element may be directly connected to the other element, or there may be an intervening element (e.g., the third element) between the element and the other element.

[0032] An embodiment of this utility model provides a spotlight with an adjustable light emission angle, such as... Figure 1-5 As shown, the lamp includes a lamp housing 100, a bracket 200, a circuit module (not shown), a drive assembly 300, a connecting rod 400, a connecting plate 500, a light-emitting device 600, and a lens assembly 700. The bracket 200, circuit module, drive assembly 300, connecting rod 400, connecting plate 500, light-emitting device 600, and lens assembly 700 are all housed within the lamp housing 100, which provides dust protection. The lamp housing 100 has an opening at the bottom, allowing light emitted by the light-emitting device 600 to exit and provide illumination. The connecting plate 500 is located below the bracket 200 and is rotatably connected to it. The connecting plate 500 can rotate in multiple directions in three-dimensional space around the center of the rotatable connection between the two. The center of the rotatable connection between the connecting plate 500 and the bracket 200 is located along the axial direction of the connecting plate 500, providing a reference for the subsequent installation of the convex ring. Both the light-emitting device 600 and the lens assembly 700 are fixed to the bottom surface of the connecting disk 500, with the lens assembly 700 located below the light-emitting device 600. When the light-emitting device 600 is working, it emits light, and the lens assembly 700 can control the diffusion angle of the light beam. When the connecting disk 500 rotates, the light-emitting device 600 rotates accordingly, causing the light emission angle of the light-emitting device 600 to change accordingly.

[0033] A convex ring 510, coaxial with the connecting plate 500, is connected to the top surface of the connecting plate 500. The convex ring 510 can be fixed to the top surface of the connecting plate 500 or integrally formed with the connecting plate 500. The convex ring 510 has a wavy top surface 520 with varying heights along its circumference. The abutment rod 400 abuts against the wavy top surface 520. The drive assembly 300 is connected to the abutment rod 400 and is used to drive the abutment rod 400 to rotate around a first axis, which is coaxial with the axis of the horizontally positioned connecting plate 500. A circuit module is connected to the drive assembly 300 and includes a wireless communication module.

[0034] In this embodiment, the wireless communication module includes, but is not limited to, a Wi-Fi module, a Bluetooth module, a 4G module, and an infrared signal module. Users can remotely send control commands to the circuit module via mobile phones, remote controls, or other terminals. The circuit module sends control signals to the drive component 300 according to the control commands, and the drive component 300 then drives the abutment rod 400 to rotate. Since the wavy top surface 520 undulates circumferentially, as the abutment rod 400 rotates, the abutment rod 400 will push the connecting plate 500 to deflect by an angle, which in turn causes the light-emitting device 600 on the bottom surface of the connecting plate 500 to deflect by an angle, thereby changing the light emission angle. Therefore, this embodiment can remotely control the spotlight to change the light emission angle, making operation more convenient.

[0035] It should be noted that since there is a corresponding relationship between the rotation position of the abutment rod 400 and the light emission angle, the corresponding relationship between the rotation position of the abutment rod 400 and the light emission angle can be determined in advance through a limited number of experiments. Then, the rotation position of the abutment rod 400 can be adjusted according to this relationship to precisely control the light emission angle.

[0036] In some embodiments, such as Figure 3-5 As shown, the drive assembly 300 includes a drive mechanism and a rotating disk 310 rotatably connected to the bracket 200. The rotation axis of the rotating disk 310 and the bracket 200 is coaxial with the first axis. The drive mechanism is connected to the rotating disk 310 and is used to drive the rotating disk 310 to rotate. The upper end of the abutment rod 400 is fixed on the rotating disk 310, and the lower end abuts against the wavy top surface 520. When the rotating disk 310 rotates, it drives the abutment rod 400 to rotate accordingly. Since the rotating disk 310 is rotatably connected to the bracket 200, it is easier to drive the rotating disk 310 to rotate than to directly drive the abutment rod 400 to rotate, which facilitates the connection between the drive mechanism and the drive disk 310. Moreover, compared to directly driving the abutment rod 400, the rotation of the drive disk 310 is relatively stable.

[0037] Furthermore, the drive mechanism includes a motor 320, and the output shaft of the motor 320 is connected to a gear 321.

[0038] In one embodiment, the outer periphery of the rotating disk 310 is provided with teeth, and the gear 321 meshes with the teeth on the outer periphery of the rotating disk 310. When the motor 320 drives the output shaft to rotate, the output shaft drives the gear 321 to rotate, and the gear 321 then drives the rotating disk 310 to rotate.

[0039] In another embodiment, a rotating ring 330 is coaxially connected to the rotating disk 310. The rotating ring 330 can be fixed to the top surface of the rotating disk 310 or integrally formed with the rotating disk 310. The inner wall of the rotating ring 330 is provided with teeth, and the gear 321 meshes with the teeth on the inner wall of the rotating ring 330. When the motor 320 drives the output shaft to rotate, the output shaft drives the gear 321 to rotate, and the gear 321 then drives the rotating disk 310 to rotate.

[0040] In this embodiment, the rotating disk 310 is driven by gear transmission. The motor 320 and its output shaft can maintain a relatively stable position and do not need to rotate with the rotating disk 310, making the driving method simpler. At the same time, the gear transmission can be speed-matched by the ratio of the gear radii, thereby allowing for more accurate control of the light emission angle.

[0041] In some embodiments, such as Figure 3-5 As shown, the rotating disk 310 has a through hole at its center, through which the bracket 200 passes. A gasket 340 is fixed on the bracket 200, located below the rotating disk 310. The bracket 200 and the gasket 340 clamp the rotating disk 310. The gasket 340 and the bracket 200 limit the rotation of the rotating disk 310, preventing it from detaching from the bracket 200 and maintaining a rotational connection between the rotating disk 310 and the bracket 200.

[0042] Meanwhile, since the connecting plate 500 is located below the bracket 200, the connecting plate 500 must be connected to the bracket 200 through the universal rotating connection structure. The gasket 340 can be placed between the universal rotating connection structure and the bracket 200 to avoid friction between the universal rotating connection structure and the bracket 200, ensure smooth movement of the universal rotating connection structure, and reduce problems such as jamming and abnormal noise during rotation.

[0043] In some embodiments, such as Figure 3-5 As shown, a universal ball joint 530 is connected to the top surface of the connecting plate 500, and a ball joint seat 350 is connected to the bracket 200. The ball joint seat 350 encloses a portion of the universal ball joint 530, and the universal ball joint 530 can rotate omnidirectionally within the ball joint seat 350. The universal ball joint is used to achieve an omnidirectional rotational connection between the connecting plate 500 and the bracket 200.

[0044] The ball joint 350 may include an upper ball joint and a lower ball joint, which are detachably connected to facilitate the assembly of the universal ball joint 530 into the ball joint 350. The top of the ball joint 350 may abut against the gasket 340, thereby pressing the gasket 340 firmly against the bracket 200.

[0045] The ball joint 350 and the bracket 200 are detachably connected for easy assembly. The universal ball joint 530 and the connecting plate 500 can be integrally molded for easy overall manufacturing.

[0046] In some embodiments, such as Figure 3-5 As shown, the top surface of the lens assembly 700 is provided with a receiving groove 710, and the light-emitting device 600 is embedded in the receiving groove 710. The receiving groove 710 can restrict the lateral movement of the light-emitting device 600 on the bottom surface of the connecting plate 500, so as to stably fix the light-emitting device 600 on the bottom surface of the connecting plate 500.

[0047] The lens assembly 700 may include a lens holder and a lens, with the lens fixed inside the lens holder. The lens holder is fixedly connected to the connecting plate 500, and the top surface of the lens holder may be provided with the receiving groove 710 described in the above embodiment.

[0048] In some embodiments, such as Figure 4 As shown, the light-emitting device 600 can be a COB light source, an LED bead, or other light-emitting device.

[0049] In some embodiments, such as Figure 1-3 As shown, the lamp housing 100 includes a bottom housing 110, a lamp tube 120 and a reflector 130. The lamp tube 120 is connected to the bottom housing 110, and the reflector 130 is fixed inside the lamp tube 120 and located below the lens assembly 700.

[0050] The lamp housing 120 is used to fix the reflector cup 130 and can extend the length of the lamp housing 100. The reflector cup 130 reflects and concentrates the light emitted by the light-emitting device 600 to form a beam.

[0051] The lamp housing 120 can be detachably connected to the base shell 110 by means of threaded connection or other means, and the reflector cup 130 can be detachably connected to the lamp housing 120 by means of snap-fit ​​connection or other means, so as to facilitate the assembly of the lamp housing 100.

[0052] Furthermore, the outer wall of the lamp holder 120 is fixed with a clip 140, which can be used to fix the entire spotlight to the panel or ceiling, and also makes it easy to remove the entire spotlight from the installation position.

[0053] In some embodiments, such as Figure 1-3 As shown, a heat sink 150 is provided on the outer surface of the bottom shell 110, which can enhance the heat dissipation effect of the spotlight.

[0054] In some embodiments, such as Figure 3-5 As shown, when the connecting plate 500 is in a horizontal state, the abutting rod 400 abuts the lowest point of the wavy top surface 520, so that the abutting rod 400 can abut the wavy top surface 520 continuously along the circumference of the connecting plate 500.

[0055] In some embodiments, such as Figure 3-5 As shown, the wavy top surface 520 can be uniformly and symmetrically arranged relative to the center of the convex ring 520. In the circumferential direction of the connecting disk 500, the wavy top surface 520 can be distributed in a sinusoidal waveform.

[0056] In some embodiments, such as Figure 1-3As shown, both the circuit module and the drive component 300 are fixed on the bracket 200, which eliminates the need to provide other mounting positions for the circuit module and the drive component 300, simplifies the installation structure, and makes the overall structure more compact, which is beneficial for the miniaturization of the spotlight.

[0057] In some embodiments, such as Figure 1-3 As shown, the circuit module also includes a control module and a drive module. Both the wireless communication module and the drive module are connected to the control module, and the drive module is connected to the drive component 300. The control module includes, but is not limited to, a microcontroller chip, which sends control signals to the drive module, which then drives the drive component 300 to operate.

[0058] The terms and words used in the foregoing description and claims are not limited to their literal meaning, but are merely used by the applicant to enable a clear and consistent understanding of the present invention. Therefore, those skilled in the art should understand that the foregoing description of various embodiments of the present invention is for illustrative purposes only, and not intended to limit the present invention as defined by the appended claims and their equivalents.
