[0031] Existing spotlights all have a one-piece, monolithic body. Once installed and fixed in a preset position, the distance between the light source and the projection area is fixed and cannot be adjusted. Furthermore, existing spotlights have complex structures and suffer from problems such as poor adjustment when adjusting the angle. Furthermore, existing spotlights have poor heat dissipation, which can easily damage the internal light source or affect the optical quality of the lens, resulting in a short service life and a poor user experience.

[0032] To address the above issues, the present invention provides a height-adjustable spotlight that allows for flexible adjustment of the height and angle of the installed spotlight, effectively adjusting the distance between the spotlight's light source and the illuminated area. This, in turn, further enhances the spotlight's practicality by adjusting the range and angle of illumination. Furthermore, the novel structure allows for smooth and convenient adjustment. Furthermore, the spotlight exhibits excellent heat dissipation, effectively preventing damage to the internal light source due to excessive temperatures, significantly extending the spotlight's service life and light color.

[0033] The technical solutions of the embodiments of the present application are described in detail below with reference to the accompanying drawings.

[0034] Example

[0035] See also Figure 1-Figure 7 The height-adjustable spotlight of the present application includes a sliding cover 1, a slider assembly 2, a heat sink 3, a light source assembly 4, and a front ring 5. The sliding cover 1 is sleeved on the heat sink 3. The slider assembly 2 is fixedly connected to the heat sink 3 and is slidably connected to the sliding cover 1, so as to enable the heat sink 3 to move relative to the sliding cover 1 to adjust the height and angle of the spotlight. The light source assembly 4 is arranged in the heat sink 3 and is connected to the power supply, which not only facilitates the protection of the light source assembly 4, but also facilitates the heat sink 3 to discharge the heat generated by the light source assembly 4 in a timely manner to reduce the temperature around the light source assembly 4, thereby improving the heat dissipation effect of the spotlight, reducing light decay, and thus extending the service life of the spotlight. The front ring 5 is arranged at the bottom end of the heat sink 3 to support the spotlight.

[0036] Specifically, the sliding cover 1 includes a rack 11 and a fixing seat 12, and the rack 11 is arranged on the fixing seat 12. Figure 1-Figure 3 As shown, the fixing base 12 includes an arcuate portion 121 and a base 122. The arcuate portion 121 and the base 122 are integrally formed and form a C-shape. The arcuate portion 121 is a quarter arc, and the base 122 is generally circular, so that the base 122 can be mounted on the heat sink 3. The two racks 11 are symmetrically arranged on the arcuate portion 121, and the extension direction of the racks 11 is consistent with the extension direction of the arcuate portion 121, which can maximize the adjustment angle and height of the spotlight.

[0037] In order to facilitate the installation of the slider assembly 2, a movable gap 13 is provided between the racks 11, and the slider assembly 2 includes a slider placement groove 21, a slider 22, a spring 23, a limit block 24, and a limit cover 25. Specifically, the slider placement groove 21 is provided at the top of the radiator 3, and when the sliding cover 1 is sleeved on the radiator 3, the slider placement groove 21 is opposite to the movable gap 13, so that the slider 22 can contact the rack 11. Preferably, the rack 11, the slider 22, the limit block 24, and the limit cover 25 are all made of stainless steel or aluminum alloy, which not only improves the stability of the structure during sliding, but also avoids the problem of deviation in the illumination angle of the spotlight due to material deformation when other materials (such as rubber) are used.

[0038] The spring 23 is disposed in the slider placement slot 21, and in a natural state, the top end of the spring 23 can extend out of the slider placement slot 21. The slider 22 is disposed above the spring 23, and the bottom surface of the slider 22 abuts against the top end of the spring 23. Thus, when the slider 22 is placed above the spring 23, the spring 23 is compressed and exerts an upward force on the slider 22, causing the spring 23 to push the slider 22 upward, thereby allowing the top surface of the slider 22 to abut against the rack 11. To further limit the position of the slider 22, the limit blocks 24 are symmetrically disposed at both ends of the slider placement slot 21, thereby preventing the slider 22 from moving inadvertently, which could result in poor spotlight adjustment. The limit cover 25 is disposed above the sliding cover 1 and is fixedly connected to the slider 22 via screws. Specifically, screw holes are provided on both the limit cover 25 and the slider 22. The screws pass through the limit cover 25, the movable gap 13, and the slider 22 in sequence, thereby connecting the limit cover 25 and the slider 22. When the slider assembly 2 is secured, the limit cover 25 is located above the rack 11, and the slider 22 is located below the rack 11 and above the radiator 3. Thus, the sliding connection between the sliding cover 1 and the radiator 3 is achieved by sliding the slider 22 on the rack 11, thereby facilitating movement of the radiator 3 relative to the sliding cover 1.

[0039] Furthermore, to facilitate the movement and retention of the slider 22 and the rack 11, the rack 11 is wavy in shape. A slide bar 221 is provided on the upper surface of the slider 22, adapted to the rack 11. When the slider 22 abuts the rack 11, the slide bar 221 is located in the tooth groove of the rack 11. To adjust the spotlight up and down or at an angle, an upward or downward force is applied to the radiator 3, allowing the slider 22 on the radiator 3 to move upward or downward along the direction of the rack 11. Since the rack 11 is curved, the height and angle of the spotlight can be adjusted by adjusting the relative position of the radiator 3 and the sliding cover 1.

[0040] like Figure 5As shown, the heat sink 3 includes a main body 31, several convection grooves 32, and a receiving cavity 33. Several of the convection grooves 32 are sequentially arranged at the top of the main body 31 to accelerate heat transfer. The receiving cavity 33 is arranged in the main body 31, and the light source assembly 4 is arranged in the receiving cavity 33. When the light source assembly 4 emits light and generates a large amount of heat, the heat sink 3 can quickly absorb the heat and discharge it. Furthermore, to facilitate the adjustment of the spotlight, the heat sink 3 also includes a protrusion 34, which is arranged at the bottom end of the main body 31. When the spotlight is installed, the bottom end of the protrusion 34 is lower than the height of the ring body of the front ring 5, allowing the user to pinch the protrusion 34 at the bottom end and drive the heat sink 3 to move or rotate. In order to increase the friction between the user and the protrusion 34, the surface of the protrusion 34 is also provided with anti-slip grooves, allowing the user to pinch the protrusion 34 securely.

[0041] The light source assembly 4 includes a light source 41, a light source mounting frame 42, a lens 43, and a lens mounting ring 44. The lens mounting ring 44 is arranged at the bottom end of the radiator 3 and is connected to the radiator 3. Specifically, the lens mounting ring 44 also includes an external thread 442. The inner side wall of the bottom end of the radiator 3 is provided with an internal thread 35 that is compatible with the external thread 442. The lens mounting ring 44 is fixed to the radiator 3 through the mutual cooperation between the external thread 442 and the internal thread 35. The lens 43 is placed on the lens mounting ring 44, the light source mounting frame 42 is arranged at the top of the lens 43, and the light source 41 is arranged on the light source mounting frame 42, that is, the light source mounting frame 42 is provided with a light-transmitting hole, and the light source 41 is arranged at the light-transmitting hole on the light source mounting frame 42, so that the light emitted by the light source 41 can be emitted through the lens 43. Furthermore, in order to facilitate the placement of the lens 43 , the lens mounting ring 44 includes a step 441 . The step 441 is provided on the inner side wall of the lens mounting ring 44 , so that the lens 43 can be placed on the step 441 .

[0042] The front ring 5 includes a ring body 51, a spring clip 52, a groove 53, and an annular groove 54. The ring body 51 is arranged at the bottom end of the radiator 3, and the area of ​​the ring body 51 is larger than the area of ​​the bottom end of the radiator 3, so that the bottom end of the radiator 3 can be placed in the ring body 51. The spring clip 52 is arranged on the ring body 51 and is fixedly connected to the ring body 51. A plurality of grooves 53 are provided on the inner side wall of the ring body 51. The annular groove 54 is also provided on the inner side wall of the ring body 51 and is connected to the grooves 53. The sliding cover 1 is provided with a protrusion 14 that is compatible with the grooves 53. When the protrusion 14 is clamped in the annular groove 54 through the groove 53, the connection between the front ring 5 and the sliding cover 1 is achieved.

[0043] When installing the spotlight, first drill a hole in the ceiling and connect the power cord to the light source 41 in the radiator 3. Then, lift the entire spotlight and move the spring clip 52 to allow the spotlight to completely enter the hole. Finally, place the bottom end of the spring clip 52 on the ceiling to support the weight of the entire spotlight. Adjust the position of the spotlight so that the lens 43 can be located in the middle of the hole, and the installation of the spotlight is completed. When adjusting the height and angle of the spotlight, the user only needs to pinch the protrusion 14 on the radiator 3 and pull it down or push it up so that the slider 22 can move downward or upward relative to the sliding cover 1. In this process, the front ring 5 and the sliding cover 1 remain stationary, and the radiator 3 (including the light source assembly 4) moves downward or upward relative to the sliding cover 1 along the direction of the rack 11, thereby changing the upper and lower heights and angles of the light source assembly 4 to achieve height and angle adjustment of the spotlight. Furthermore, the user can also pinch the protrusion 14 on the radiator 3 and rotate it clockwise or counterclockwise. Since the protrusion 14 on the sliding cover 1 is stuck in the annular groove, the radiator 3 can drive the sliding cover 1 to rotate clockwise or counterclockwise, thereby allowing the entire sliding cover 1 and the radiator 3 (including the light source assembly 4) to rotate horizontally.

[0044] In this embodiment, the present application provides a height-adjustable spotlight, comprising a sliding cover, a slider assembly, a heat sink, a light source assembly, and a front ring. By providing a sliding cover and a slider assembly, and providing an arc-shaped rack, the heat sink can be moved relative to the sliding cover along the direction of the rack, thereby flexibly adjusting the height and angle of the installed spotlight, and thus effectively adjusting the distance and angle between the spotlight light source and the irradiation area. Furthermore, by providing a protrusion on the sliding cover and a ring groove on the front ring, the light source can be driven to rotate horizontally by the rotation of the heat sink, thereby enriching the adjustment method of the spotlight and further improving the practicality of the spotlight. By providing a protrusion at the bottom end of the heat sink, it is convenient for the user to adjust the angle and height of the spotlight, and the structure is novel and the adjustment is convenient and smooth. By providing a heat sink, the spotlight can have a better heat dissipation effect, effectively preventing the internal light source from being damaged due to excessive temperature, and greatly improving the service life and light color effect of the spotlight.
