[0029] Combination Figure 1 and Figure 2 As shown, this utility model embodiment provides a spotlight fixture, including a fixing component 10, a convex lens component 20, and a light source component 30. The fixing component 10 has a receiving cavity 12 with a light-transmitting opening 11. The convex lens component 20 and the light source component 30 are disposed in the receiving cavity 12. The convex lens component 20 is closer to the light-transmitting opening 11 than the light source component 30. The light emitted by the light source component 30 is refracted by the convex lens component 20 and then emitted from the light-transmitting opening 11. The focal length between the convex lens component 20 and the light source component 30 is greater than 16mm.

[0030] In this embodiment, the fixing component 10 has a receiving cavity 12 inside, and the receiving cavity 12 has a light-transmitting opening 11 for light emission. The convex lens component 20 and the light source component 30 are jointly disposed in the receiving cavity 12, and the convex lens component 20 is located in the light emission direction of the light source component 30, and is positioned relative to the light source component 30 close to the light-transmitting opening 11, so that the light emitted by the light source component 30 is refracted by the convex lens component 20 and then emitted through the light-transmitting opening 11. To achieve a good light-focusing effect, a focal length greater than 16mm is provided between the convex lens component 20 and the light source component 30, thereby ensuring that the refracted light forms an ultra-small angle beam of 8°-10°, obtaining a concentrated light spot effect.

[0031] In one embodiment, the fixing component 10 includes a fixing part 13, on which an annular mounting opening 131 is provided, and the convex lens component 20 is disposed in the annular mounting opening 131.

[0032] In this embodiment, the fixing component 10 includes a fixing part 13 for supporting and mounting various components. The fixing part 13 is provided with an annular mounting opening 131 for mounting the convex lens assembly 20. Specifically, the annular mounting opening 131 is annularly formed on the fixing part 13, and its size and structure match the shape of the convex lens assembly 20, so that the convex lens assembly 20 can be securely embedded in the annular mounting opening 131. Through this structural design, the positional stability of the convex lens assembly 20 in the optical axis direction can be effectively ensured, thereby helping to maintain the set focal length between the light source assembly 30 and the convex lens assembly 20, further ensuring the good optical performance of the spotlight. In addition, the annular mounting opening 131 facilitates the quick installation and replacement of the convex lens assembly 20, improving the product assembly efficiency and maintenance convenience.

[0033] Combination Figure 3As shown, in one embodiment, the convex lens assembly 20 includes a convex lens body 21, a first textured portion 22 and a second textured portion 23. The first textured portion 22 is disposed at the bottom of the convex lens body 21, and the second textured portion 23 surrounds the periphery of the first textured portion 22. The sides of the first textured portion 22 and the second textured portion 23 facing the light source assembly 30 are textured, and the textured degree of the second textured portion 23 is greater than that of the first textured portion 22.

[0034] In this embodiment, the convex lens body 21 is used to refract and focus the light from the light source assembly 30 to achieve a small-angle light emission effect. To optimize the light-gathering performance and improve the light spot quality, the bottom of the convex lens body 21 is provided with a first textured portion 22, and a second textured portion 23 is further provided around the periphery of the first textured portion 22. Both the first textured portion 22 and the second textured portion 23 face the side of the light source assembly 30 and are textured to adjust the light distribution. The textured degree of the second textured portion 23 (heavy textured) is greater than that of the first textured portion 22 (light textured) to enhance the ability to control the scattering of peripheral light, thereby effectively suppressing the bright ring phenomenon around the light spot while achieving a good light-gathering effect. This partitioned textured design makes the central light spot more concentrated and the edge transition smoother, improving the uniformity of the illumination spot.

[0035] In one embodiment, the side of the second textured portion 23 facing the light source assembly 30 is closer to the light source assembly 30 than the side of the first textured portion 22 facing the light source assembly 30.

[0036] In this embodiment, to further improve the light control effect, the side of the second textured part 23 facing the light source assembly 30 is closer to the light source assembly 30 than the side of the first textured part 22 facing the light source assembly 30. Specifically, the second textured part 23 is located on the stepped structure at the bottom of the convex lens body 21, forming a structural layout with a lower height than the first textured part 22, making the distance between its textured surface and the light source assembly 30 relatively shorter. This structural design not only helps to enhance the interference capability of the second textured part 23 on the peripheral diverging light, but also further optimizes the distribution state of light before entering the convex lens body 21, thereby improving the overall light focusing effect and light spot quality. By setting the textured areas at different heights according to functional differences, differentiated control of the center light and the edge light can be effectively achieved, avoiding the bright ring phenomenon and improving the application performance of the lamp in small-angle lighting scenarios.

[0037] Combination Figure 4 As shown, in one embodiment, a limiting portion 132 is provided around the annular mounting port 131, and the convex lens assembly 20 further includes a support portion 24 connected at one end to the convex lens assembly 20, the other end of the support portion 24 being supported on the bottom of the receiving cavity 12, and the side of the second textured portion 23 away from the light source assembly 30 abutting against the limiting portion 132.

[0038] In this embodiment, to ensure the installation stability and optical alignment accuracy of the convex lens assembly 20 within the receiving cavity 12, a limiting portion 132 is provided around the annular mounting opening 131 for limiting and positioning the convex lens assembly 20. The convex lens assembly 20 also includes a support portion 24, one end of which is connected to the convex lens assembly 20, and the other end is supported on the bottom of the receiving cavity 12, thereby forming a fixed support structure in the optical axis direction to prevent axial displacement of the convex lens assembly 20. Furthermore, the side of the second textured portion 23 away from the light source assembly 30 abuts against the limiting portion 132. Through the positioning effect of the limiting portion 132 on the second textured portion 23, the convex lens assembly 20 can be reliably embedded in the annular mounting opening 131, and the set spatial relationship of its textured surface and the relative positional relationship with the light source assembly 30 are maintained, effectively ensuring the stability of the preset focal length and optical path.

[0039] In one embodiment, the support portion 24 includes a plurality of support columns, which are spaced apart along the second textured portion 23.

[0040] In this embodiment, the support portion 24 includes multiple support columns, which are spaced apart circumferentially along the second textured portion 23. Specifically, each support column extends from the bottom of the convex lens assembly 20 and connects to the bottom of the receiving cavity 12, providing good structural support for the convex lens assembly 20 without affecting the optical path. By evenly distributing the support columns in the peripheral area of ​​the second textured portion 23, the main light-emitting area can be effectively avoided from being blocked, ensuring sufficient light transmission while maintaining the installation stability and focal length accuracy of the lens assembly. In addition, the spaced support column structure facilitates mold design and manufacturing, which is beneficial for mass production. The overall structure is simple and stable, making it suitable for lighting products with high requirements for focusing accuracy and assembly efficiency.

[0041] In one embodiment, a reflective component 40 is also included. The reflective component 40 is disposed in front of the light-emitting direction of the convex lens assembly 20. The reflective component 40 has a light-emitting port 41 at the position corresponding to the light-transmitting port 11. The diameter of the light-emitting port 41 gradually increases in the light-emitting direction. A reflective surface 42 is disposed on the inner side of the reflective component 40.

[0042] In this embodiment, to further enhance beam control and focusing effect, the spotlight also includes a reflector 40. The reflector 40 is positioned in front of the convex lens assembly 20 in the light-emitting direction, covering the outside of the light-transmitting opening 11, and is used for secondary control of the light refracted by the convex lens assembly 20. The reflector 40 has a light-emitting opening 41 at a position corresponding to the light-transmitting opening 11. The diameter of the light-emitting opening 41 gradually increases along the light-emitting direction (i.e., away from the light source assembly 30), forming a trumpet-shaped gradually opening structure, which facilitates guiding light to form a concentrated beam output. To enhance light guiding and shaping effects, a reflective surface 42 is provided on the inner side of the reflector 40. The reflective surface 42 can be a smooth curved surface or a highly reflective surface treated with a metal coating, used to reflect and concentrate some scattered light, thereby further improving the brightness and uniformity of the emitted light spot. By setting the reflector 40 in front of the convex lens assembly 20, not only can the edge transition of the light spot be improved, but also the overflow of some stray light can be suppressed, improving the overall lighting quality.

[0043] In one embodiment, the fixing component 10 further includes a heat dissipation section 14, the receiving cavity 12 is located inside the heat dissipation section 14, and the light source component 30 is connected to the heat dissipation section 14.

[0044] In this embodiment, to ensure that the heat generated by the light source assembly 30 during operation can be effectively dissipated, thereby maintaining its stable luminous performance and extending its service life, the fixing assembly 10 also includes a heat dissipation section 14. A receiving cavity 12 is disposed inside the heat dissipation section 14 and is used to install and protect the convex lens assembly 20 and the light source assembly 30. The heat source of the light source assembly 30 is concentrated, and it is directly connected to the heat dissipation section 14 through its back, allowing the heat generated during operation to be quickly conducted to the heat dissipation section 14 and efficiently dissipated through its external structure. The heat dissipation section 14 can be made of a metal material with excellent thermal conductivity (such as aluminum alloy), and its surface can be designed with heat dissipation fins or other structures to enhance heat dissipation efficiency as needed. This heat dissipation structure design not only improves the overall heat dissipation capacity of the spotlight fixture, ensuring stable operation of the light source assembly 30 under high power conditions, but also helps to improve the reliability and service life of the entire lamp, making it suitable for high-performance applications requiring long-term continuous lighting.

[0045] In one embodiment, the fixing part 13 includes a first fixing part 133 and a second fixing part 134. One end of the first fixing part 133 is connected to the second fixing part 134, and the other end of the first fixing part 133 is connected to the reflective component 40. The second fixing part 134 is connected to the heat dissipation part 14, and an annular mounting port 131 is disposed on the second fixing part 134.

[0046] In this embodiment, one end of the first fixing part 133 is connected to the second fixing part 134, and the other end is connected to the reflective assembly 40. This supports and fixes the reflective assembly 40 above the light-emitting direction of the light-transmitting port 11, ensuring its coaxiality with the optical axis of the convex lens assembly 20 and the light source assembly 30. The second fixing part 134 is disposed on the heat dissipation part 14, forming a stable connection structure with it, and is used to support the receiving cavity 12 and its internal components. An annular mounting opening 131 is disposed on the second fixing part 134, and the convex lens assembly 20 is installed within this annular mounting opening 131, thereby achieving the positioning and fixation of the convex lens assembly 20. The segmented design of the first fixing part 133 and the second fixing part 134 not only facilitates the independent assembly and maintenance of each functional module but also improves the overall stability and assembly flexibility of the lighting fixture.

[0047] In one embodiment, the light source assembly 30 is a COB light source.

[0048] In this embodiment, the light source assembly 30 is a COB (Chip on Board) light source. This COB light source features a small luminous surface size, high luminous flux, and uniform light emission, making it suitable for high-brightness, small-angle lighting applications. Combined with the focusing optical design of this invention, the COB light source preferably adopts a les size of 3mm or 4mm, which is beneficial for achieving an ultra-small focusing angle effect of 8° to 10°. Compared with the widely used 3030 or 3535 packaged LEDs, the COB light source not only supports higher power output but also has higher cost-effectiveness, making it suitable for commercial mass production and widespread application. By combining the COB light source with the optimized convex lens assembly 20, not only are the luminous efficacy and beam quality improved, but manufacturing costs are also effectively reduced, enhancing the overall performance of the spotlight in practical applications.
