[0030] Please see Figure 1 This invention provides an adjustable spotlight 10, comprising: a front ring 100, an optical lens 101, a focusing element 102, a lamp body 103, and a heat sink 104, wherein a light source is fixed on the heat sink 104; wherein the optical lens 101 is fixed to one end of the focusing element 102 via the front ring 100; a cavity 1031 is provided inside the lamp body 103, and the focusing element 102 is located in the cavity 1031, and the focusing element 102 is rotatably connected along the axial direction. At one end of the lamp body 103, a first limiting structure 105 is provided between the lamp body 103 and the focusing member 102 to limit the axial movement of the focusing member 102 in the cavity 1031; the heat sink 104 is threadedly connected to the focusing member 102 and the heat sink 104 can move axially relative to the lamp body 103, and a second limiting structure 106 is provided between the heat sink 104 and the lamp body 103 to limit the rotation of the heat sink 104.

[0031] In this embodiment, the focusing element 102 is located within a cavity 1031 inside the lamp body 103 and can rotate axially along one end of the lamp body 103. To ensure that the focusing element 102 does not move axially within the cavity 1031 when adjusting the angle, a first limiting structure 105 is designed between the lamp body 103 and the focusing element 102. The heat sink 104 is connected to the focusing element 102 via a threaded structure and can move axially relative to the lamp body 103. To prevent the heat sink 104 from rotating during adjustment, a second limiting structure 106 is provided between the heat sink 104 and the lamp body 103. This second limiting structure 106 restricts the heat sink 104 to move axially only within the cavity 1031 of the lamp body 103 and prevents it from rotating axially.

[0032] In summary, through the axial rotation of the focusing component 102 and the cooperation of the first limiting structure 105, users can flexibly adjust the illumination angle of the spotlight as needed to meet the lighting requirements of different scenarios. The threaded connection design between the heat sink 104 and the focusing component 102 allows the focusing component 102 to rotate axially relative to the heat sink 104. At the same time, the second limiting structure 106 ensures that the heat sink 104 will not rotate during movement but can only move axially, thus realizing the adjustment of the relative distance between the heat sink 104 and the focusing component 102, thereby achieving the focusing function.

[0033] Furthermore, such as Figure 3 and Figure 4As shown, the first limiting structure 105 includes an annular retaining spring 1051, a retaining hole 1052 disposed on the focusing member 102, and an annular retaining groove 1053 disposed on the inner wall of the lamp body 103. The annular retaining spring 1051 has a protruding retaining part 10511. The annular retaining spring 1051 is built into the focusing member 102, and the retaining part 10511 protrudes from the retaining hole 1052 and abuts against the annular retaining groove 1053.

[0034] In this embodiment, the annular retaining spring 1051 in the first limiting structure 105 engages with the annular retaining groove 1053 through its engaging portion 10511, thereby restricting the axial movement of the focusing member 102 within the cavity 1031. The engaging portion 10511 of the annular retaining spring 1051 protrudes from the retaining hole 1052 of the focusing member 102 and abuts against the annular retaining groove 1053 on the inner wall of the lamp body 103, thus achieving the limiting function of the focusing member 102. The annular retaining spring 1051 is built into the focusing member 102, making the structure compact and not affecting the rotation function of the focusing member 102.

[0035] During assembly, the annular retaining spring 1051 is embedded within the focusing component 102, with its engaging portion 10511 protruding through the retaining hole 1052 of the focusing component 102. Then, the entire focusing component 102 is inserted into the cavity 1031 of the lamp body 103 until the engaging portion 10511 of the annular retaining spring 1051 contacts and abuts against the annular groove 1053 on the inner wall of the lamp body 103. When the focusing component 102 rotates along its axis within the lamp body 103, the engaging portion 10511 of the annular retaining spring 1051 is restricted by the annular groove 1053, limiting the movement of the focusing component 102 to a certain range. This achieves the function of limiting the axial movement of the focusing component 102.

[0036] In summary, by setting the first limiting structure 105, this embodiment not only realizes the axial rotational connection of the focusing component 102 in the cavity 1031, but also effectively restricts its axial movement, thereby enhancing the flexibility of the angle-adjusting spotlight 10 and meeting the diverse lighting needs in different scenarios.

[0037] Furthermore, multiple latching portions 10511 are provided and spaced apart, and multiple corresponding latching holes 1052 are provided. Preferably, the multiple and spaced-apart latching portions 10511 help improve the stability and reliability of the latching. Multiple latching holes 1052 are also provided to correspond with the latching portions 10511, achieving a more secure connection. In this way, it is possible to effectively prevent the focusing component 102 from accidentally loosening or falling off during use. Specifically, the annular spring 1051 can be made of an elastic material to provide a certain degree of elastic deformation during latching, increasing the firmness of the latching. The design of the latching holes 1052 can also be adjusted according to actual needs.

[0038] Furthermore, such as Figure 2 and Figure 5 As shown, the second limiting structure 106 includes a groove 1061 axially arranged along the inner wall of the lamp body 103 and a slider 1062 disposed on the outer edge of the heat sink 104. The slider 1062 can slide axially along the groove 1061. In this embodiment, the groove 1061 can be implemented by forming a groove on the inner wall of the lamp body 103, while the slider 1062 can be implemented by forming a protrusion on the outer edge of the heat sink 104. The cooperation between the slider 1062 and the groove 1061 should ensure that the slider 1062 can slide smoothly in the groove 1061. That is, by axially setting the groove 1061 on the inner wall of the lamp body 103 and setting the slider 1062 on the outer edge of the heat sink 104, the slider 1062 can slide axially along the groove 1061, thereby restricting the rotation of the heat sink 104. Thus, the angle-adjustable spotlight 10 can realize the axial movement of the light source, meet the focusing requirements, improve the flexibility of spotlight use, and meet the lighting needs in different scenarios.

[0039] Furthermore, a third limiting structure 107 is provided between the heat sink 104 and the lamp body 103 to limit the maximum movement distance of the heat sink 104 toward the other end of the lamp body 103. In this embodiment, when the heat sink 104 moves to the maximum movement distance toward the other end of the lamp body 103, the limiting protrusion 1071 will abut against the heat sink 104, thereby limiting further movement of the heat sink 104. This design ensures the range of movement of the heat sink 104, preventing it from exceeding the predetermined position during adjustment and maintaining the stability and safety of the lamp.

[0040] Specifically, the third limiting structure 107 includes a limiting protrusion 1071 disposed on the inner wall of the lamp body 103. When the heat sink 104 moves toward the other end of the lamp body 103 to the maximum moving distance, the limiting protrusion 1071 abuts against the heat sink 104.

[0041] In this embodiment, in the initial state of the spotlight, a certain gap is maintained between the contact surface of the heat sink 104 and the limiting protrusion 1071 inside the lamp body 103, allowing the heat sink 104 to move freely under the action of the focusing member 102. When the focusing member 102 rotates along the lamp axis, the heat sink 104 moves up and down along the slide groove 1061 of the lamp body 103 under the action of the multi-threaded screw. As the heat sink 104 moves, its contact surface gradually approaches the limiting protrusion 1071. Once the contact surface of the heat sink 104 contacts the limiting protrusion 1071, further movement of the heat sink 104 will be restricted. At this time, the heat sink 104 has moved to its maximum allowable distance and can no longer move. At this time, the heat sink 104 and the focusing member 102 still maintain a threaded connection. The relative distance between the heat sink 104 and the focusing element 102 is adjusted by rotating their threads. When the distance between the heat sink 104 and the focusing element 102 increases, the light emission angle through the optical lens 101 decreases; conversely, when the distance between the heat sink 104 and the focusing element 102 decreases, the light emission angle through the optical lens 101 increases. In other words, the distance between the light source on the heat sink 104 and the optical lens 101 changes with the relative distance between the heat sink 104 and the focusing element 102. It should be noted that regardless of whether the adjustment distance between the heat sink 104 and the focusing element 102 increases or decreases, the heat sink 104 and the focusing element 102 remain threadedly connected. Furthermore, when the adjustment distance between the heat sink 104 and the focusing element 102 increases to a certain extent—that is, when the heat sink 104 contacts the limiting protrusion 1071—the heat sink 104 has moved to its maximum allowable distance and can no longer move.

[0042] In summary, through the tight fit between the limiting protrusion 1071 and the contact surface of the radiator 104, the third limiting structure 107 ensures the stability and safety of the radiator 104 during movement, and avoids structural damage caused by excessive movement of the radiator 104.

[0043] It should be noted that the limiting protrusion 1071 can be a protrusion structure directly formed on the inner wall of the lamp body 103, or it can be an independent component fixed to the inner wall of the lamp body 103 by means of bonding, welding, etc. The shape and size of the limiting protrusion 1071 can be adjusted according to actual needs to adapt to heat sinks 104 of different sizes and shapes. In addition, the material of the limiting protrusion 1071 can be selected from materials with certain strength and durability, such as metal and plastic, to ensure its reliability and durability during use.

[0044] Furthermore, such as Figure 6As shown, the outer wall of the front ring 100 is provided with an external thread 1001, the inner wall of the focusing member 102 is provided with an internal thread 1021 that connects to the external thread 1001, the inner wall of the focusing member 102 facing the front ring 100 is provided with a frustum 1022, and the optical lens 101 is clamped between the frustum 1022 and the end of the front ring 100.

[0045] In this embodiment, a threaded connection between the front ring 100 and the focusing component 102 is achieved by providing an external thread 1001 on the outer wall of the front ring 100 and an internal thread 1021 connected to the external thread 1001 on the inner wall of the focusing component 102. This connection method not only improves the stability between components but also facilitates installation and disassembly.

[0046] The inner wall of the end of the focusing member 102 facing the front ring 100 is designed in the shape of a frustum. When the front ring 100 is rotated and tightly fixed on the focusing member 102, the end of the front ring 100 and the frustum 1022 inside the focusing member 102 together hold the optical lens 101, ensuring the stability of the optical lens 101 and avoiding loosening or displacement that may occur during long-term use.

[0047] By precisely controlling the position and fixing method of the optical lens 101, the lighting effect of the spotlight can be further optimized. The optical lens 101 can accurately focus and disperse light, thereby achieving the desired lighting pattern and spot shape.

[0048] Furthermore, such as Figure 1 As shown, the adjustable spotlight 10 also includes an optical film 108, which is fixed to the optical lens 101. In this embodiment, the optical film 108 is a thin film material fixed to the optical lens 101, which typically possesses specific optical properties such as light transmittance, reflectivity, and scattering. In spotlight design, the optical film 108 can adjust the direction of light propagation, making the light more evenly distributed within the target area. This helps reduce unevenness in brightness within the light spot and improves lighting quality.

[0049] Furthermore, the angle-adjustable spotlight 10 also includes a base 109, which is detachably connected to the other end of the lamp body 103. Specifically, the detachable connection between the base 109 and the lamp body 103 can be achieved in various ways, such as using a snap-fit ​​connection, a threaded connection, or a magnetic connection. These connection methods all feature easy installation and good stability. Through this design, users can easily replace the lamp or adjust its position as needed, greatly improving the adaptability and lifespan of the lamp.

[0050] Furthermore, the adjustable spotlight 10 also includes a power-taking head 1010, which is provided with conductive contacts. A circuit board is disposed inside the base 109, and the conductive contacts of the power-taking head 1010 are electrically connected to the circuit board. In this embodiment, the power-taking head 1010 is electrically connected to the circuit board inside the base 109 through conductive contacts, thereby realizing the transmission of electrical energy. Specifically, the conductive contacts of the power-taking head 1010 are electrically connected to the circuit board, allowing electrical energy to be transmitted through the power-taking head 1010 to the circuit board, thus providing power to the light source of the spotlight. Therefore, through this design, the power supply to the spotlight can be realized, ensuring its normal operation.

[0051] The various embodiments in this specification are described in a progressive manner, with each embodiment focusing on its differences from other embodiments. Similar or identical parts between embodiments can be referred to interchangeably.
