[0036] In order to make the purpose, technical solutions and advantages of the present invention more clear, the present invention is described in detail below with reference to the accompanying drawings and specific embodiments.

[0037] It should be noted here that in order to avoid obscuring the present invention due to unnecessary details, only the structures and / or processing steps closely related to the scheme of the present invention are shown in the accompanying drawings, while other details that are not closely related to the present invention are omitted.

[0038] In addition, it should be noted that the terms "comprises", "includes" or any other variations thereof are intended to cover non-exclusive inclusion, so that a process, method, article or apparatus that includes a series of elements includes not only those elements, but also includes other elements not explicitly listed, or also includes elements inherent to such process, method, article or apparatus.

[0039] See also Figures 1 and 2 FIG. 1 shows a lamp 100 according to a preferred embodiment of the present invention, comprising a first lamp body 1, a second lamp body 2, a focusing member 3, a light source assembly 4, a first optical member 5, and a second optical member 6. Lamp 100 is a multi-color, focusable lamp. Combining a multi-color light source with an adjustable focus function, users can select the desired degree of focus for each light source color, thereby meeting lighting needs in various occasions.

[0040] The first lamp body 1 and the second lamp body 2 are cylindrical, the second lamp body 2 is coaxially arranged with the first lamp body 1, and the second lamp body 2 can rotate around the axis, that is, the first lamp body 1 and the second lamp body 2 rotate coaxially, and the interiors of the first lamp body 1 and the second lamp body 2 jointly form a connected inner cavity 11.

[0041] The focusing member 3 is located in the inner cavity 11, and can rotate and be fixed to the second lamp body 2, so that the focusing member 3 is relatively stationary with the second lamp body 2 in the rotation direction of the second lamp body 2. That is to say, the focusing member 3 rotates synchronously with the second lamp body 2. The user only needs to rotate the second lamp body 2 to simultaneously drive the focusing member 3 to rotate, thereby realizing the focusing operation. There is no need to directly operate the focusing member 3, which simplifies the operation process.

[0042] The focusing member 3 can move relative to the second lamp body 2 along the axis, which is the axis when the first lamp body 1 and the second lamp body 2 rotate coaxially. Figures 3 and 4 As shown, the inner wall of the inner cavity 11 at the second lamp body 2 is provided with a first positioning portion 21, and the focusing member 3 is provided with a second positioning portion 31 at a position corresponding to the first positioning portion 21. One of the first positioning portion 21 and the second positioning portion 31 is a slot extending along the axis, and the other is a protrusion that matches the slot. In this embodiment, the first positioning portion 21 is a slot, and the second positioning portion 31 is a protrusion that slides along the axis within the slot. The secure and reliable positioning and snap-fit ​​connection between the first and second positioning portions 21 and 31 ensures the stability and accuracy of the focusing member 3 during rotation, avoiding inaccurate focusing caused by looseness or misalignment.

[0043] The focusing member 3 also engages with the light source assembly 4 through a threaded connection, so that when the second lamp body 2 rotates relative to the first lamp body 1, the focusing member 3 rotates relative to the light source assembly 4 through the threaded connection, thereby moving the focusing member 3 along the axis relative to the light source assembly 4. This threaded connection allows the user to easily adjust the focal length of the light source when needed. By rotating the focusing member 3, the illumination distance and focus effect of the light source can be precisely controlled to meet the lighting needs of different scenarios.

[0044] For details, please refer to Figure 5 As shown, the light source assembly 4 includes a base 41, which is fixedly connected to the first lamp body 1. The outer wall of the base 41 is provided with a first thread 411, and the inner wall of the focusing member 3 is provided with a second thread 32 corresponding to the first thread 411. The focusing member 3 is sleeved on the outside of the base 41, and the focusing member 3 and the base 41 are threadedly engaged via the first thread 411 and the second thread 32. The first thread 411 is a ridge formed on the outer wall of the base 41 and extends spirally along the extension axis, while the second thread 32 is a groove formed on the inner wall of the focusing member 3 and extends spirally along the extension axis. Regardless of the position to which the focusing member 3 is rotated, a portion of the focusing member 3 always overlaps with the base 41. The focusing member 3 and the base 41 are threadedly connected at the overlapping portion, enabling a direct threaded connection between the focusing member 3 and the base 41. This allows the focusing member 3 to move relative to the light source assembly 4 in the direction of the extension axis, allowing the second optical element 6 to move away from or closer to the light source assembly 4, thereby achieving focusing. The structure is simple and easy to operate.

[0045] That is to say, when the second lamp body 2 is rotated, the second lamp body 2 and the first lamp body 1 have the same rotation axis. At this time, the focusing part 3 rotates synchronously with the second lamp body 2. At the same time, since the focusing part 3 is threadedly connected to the base 41, the focusing part 3 moves back and forth along the axis driven by the thread. At this time, the protrusion slides back and forth in the slide groove, so that the second optical part 6 moves along the axis relative to the light source assembly 4 and the first optical part 5 fixedly connected to the light source assembly 4, and finally adjusts the distance between the second optical part 6 and the light source assembly 4 to achieve focusing.

[0046] The end of the second lamp body 2 away from the first lamp body 1 is provided with an anti-glare cover 22, see Figure 6 As shown, the anti-glare cover 22 includes a connecting end 221, a guide portion 222, and a limiting end 223, which are arranged in sequence. The connecting end 221 is fixed to the end of the second lamp body 2. The guide portion 222 extends obliquely from the connecting end 221 toward the interior of the second lamp body 2 and toward the second optical element 6. The limiting end 223 is connected to the guide portion 222 and extends toward the second optical element 6. The limiting end 223 is configured to limit the maximum displacement distance of the second optical element 6 within the second lamp body 2. The anti-glare cover 22 effectively prevents light from directly impinging on the human eye, reducing glare and ensuring that users do not experience glare or discomfort when using or viewing the light source.

[0047] See also Figures 7 and 8 As shown, a retaining member 23 is further provided within the second lamp body 2. The retaining member 23 includes a first end 231 and a second end 232 disposed opposite each other, and an annular circumferential wall 233 located between the first end 231 and the second end 232. The first end 231 is configured to engage with the retaining end 223. When the focusing member 3 moves to its maximum displacement, the first end 231 abuts against the retaining end 223 of the anti-glare cover 22, thereby retaining the focusing member 3 at its maximum displacement and preventing it from escaping from the second lamp body 2, significantly enhancing the safety and reliability of the lamp 100. The second end 232 is configured to abut and securely engage the second optical member 6. A first latching portion 2341 is provided on the annular circumferential wall 233, and a second latching portion 33 is correspondingly provided on the focusing member 3. The retaining member 23 and the focusing member 3 are secured by the second latching portion 33 and the first latching portion 2341.

[0048] A step portion 34 is provided in the focusing member 3, and the second optical member 6 includes an optical portion 61 and an outer edge portion 62 provided around the optical portion 61, the outer edge portion 62 is abutted and mounted on the step portion 34, and a plurality of notches 621 are provided on the outer edge portion 62; an elastic arm 234 is provided on the annular circumferential wall 233 of the limiting member 23, and a first snap portion 2341 is provided on the elastic arm 234, and a free end 2342 of the elastic arm 234 extends beyond the second end 232; the second end 232 abuts against an end of the outer edge portion 62 facing away from the step portion 34, and the free end 2342 extends into the notch 621 to limit and fix the second optical member 6 between the limiting member 23 and the focusing member 3.

[0049] In other words, the stopper 23 engages both the focusing element 3 and the second optical element 6, securing the three together. This snap-fit ​​structure ensures a tight fit between the components, ensuring the stable position of the second optical element 6 during focusing, without any shaking or shifting, thereby ensuring precise focusing. This snap-fit ​​connection makes installation and removal of the second optical element 6 simple and quick, eliminating the need for additional tools or materials, and reducing installation and maintenance costs.

[0050] See also Figure 9 As shown, light source assembly 4 is disposed within inner cavity 11 and fixed to first lamp body 1. It includes a base 41 and a light source substrate 42 mounted on base 41. Base 41 is fixedly connected to first lamp body 1, ensuring the stability of light source assembly 4 and making the entire light source system more stable and less prone to shaking. Light source substrate 42 is provided with light-emitting elements of two or more colors, enabling light source assembly 4 to emit light in multiple colors. By controlling the brightness and flashing frequency of the light-emitting elements of different colors, the overall color tone and atmosphere of the light source can be easily adjusted to create different lighting effects.

[0051] See also Figure 10As shown, the light source assembly 4 includes a first light-emitting module 421 and a second light-emitting module 422. The second light-emitting module 422 is arranged around the first light-emitting module 421. The first light-emitting module 421 includes a plurality of first light-emitting elements 4211, and the second light-emitting module 422 includes a plurality of first light-emitting elements 4211 and a plurality of second light-emitting elements 4221. The color temperature of the second light-emitting elements 4221 is different from the color temperature of the first light-emitting elements 4211. In addition, in the second light-emitting module 422, the plurality of first light-emitting elements 4211 and the plurality of second light-emitting elements 4221 are alternately arranged. Light-emitting elements of different color temperatures can provide more color options, allowing the light source assembly 4 to emit light of multiple colors. The alternating arrangement design helps achieve a uniform blend of colors, producing gradient or specific lighting effects, and enhancing visual appeal. This arrangement also allows for dynamic adjustment of the color temperature of the light source to create a warm or cool ambient effect. In other embodiments, the first light-emitting module 421 and the second light-emitting module 422 may both include light-emitting components of multiple color temperatures. For example, the first light-emitting module 421 includes red light-emitting components, yellow light-emitting components, and white light-emitting components arranged in an array, and the second light-emitting module 422 includes evenly distributed yellow light-emitting components and blue light-emitting components. The present invention does not limit the color temperature of the light-emitting components on the first light-emitting module 421 and the second light-emitting module 422, and can be adjusted according to actual needs.

[0052] Furthermore, a plurality of light sources may be provided in the inner cavity 11 . In this embodiment, a common monochromatic light source is further provided above the light source substrate 42 to achieve a better lighting effect.

[0053] See also Figure 10 As shown, the first optical element 5 and the second optical element 6 are sequentially arranged on the light output path of the light source assembly 4, and the distance between the first optical element 5 and the light source assembly 4 is smaller than the distance between the second optical element 6 and the light source assembly 4. The first optical element 5 is fixed to the light source assembly 4, ensuring that the light emitted by the light source assembly 4 first passes through the first optical element 5 for preliminary optical processing, such as light uniformity and diffusion. The second optical element 6 is fixed to the focusing element 3, and driven by the focusing element 3, the second optical element 6 can move closer to or farther from the light source assembly 4, further focusing or diffusing the light, and optimizing the light distribution and projection effect.

[0054] The first optical element 5 comprises a reflector 51 and a light-mixing film 52. The reflector 51, positioned outside the light-emitting element, effectively reflects and concentrates the light emitted by the light source assembly 4, maximizing its utilization and minimizing light waste, thereby enhancing the lighting effect. The light-mixing film 52, covering the end of the reflector 51 away from the light-emitting element, performs secondary processing on the light, making it more uniform and soft through diffuse reflection or scattering, reducing light spots and shadows, and improving visual comfort. The combination of the reflector 51 and the light-mixing film 52 produces a uniform and soft light spot, resulting in a more natural and aesthetically pleasing lighting effect.

[0055] The second optical element 6 is a lens, and the second optical element 6 has a minimum displacement point and a maximum displacement point relative to the light source assembly 4 in the axial direction of the rotating shaft. That is, the second optical element 6 moves within a moving range relative to the light source assembly 4 in the axial direction of the rotating shaft. When the second optical element 6 moves along the extension axis direction until it abuts against the first optical element 5, the second optical element 6 is located at the minimum displacement point. When the second optical element 6 moves along the extension axis direction until the first end 231 of the focusing element 3 abuts against the limit end 223 of the anti-glare cover 22, the second optical element 6 is located at the maximum displacement point.

[0056] The difference between the maximum displacement and the minimum displacement is 12 mm ± 0.5 mm. The large focusing range enables the lamp 100 to adapt to different application scenarios and lighting requirements. Whether close-range zoom or long-range projection is required, it can be achieved by adjusting the position of the second optical element 6.

[0057] At its minimum displacement, the lamp 100 has a maximum beam angle of 55°±2°. At its maximum displacement, the lamp 100 has a minimum beam angle of 20°±2°. The beam angle of the lamp 100 can be adjusted within this range, making it suitable for different scenarios and providing flexibility.

[0058] The radial path of the light-emitting surface of the second optical element 6 extending radially from the center of the second optical element 6 to its outer peripheral edge is a non-uniform rational B-spline curve, and the surface formed by rotating the curve around the axis of the second optical element 6 is a non-uniform rational B-spline surface.

[0059] Preferably, a first damping member 7 is provided between the outer surface of the base 41 and the inner surface of the focusing member 3, a second damping member 8 is provided between the inner surface of the first lamp body 1 and the outer surface of the second lamp body 2, and a third damping member 9 is provided between the outer surface of the focusing member 3 and the inner surface of the second lamp body 2. The first damping member 7, the second damping member 8, and the third damping member 9 cooperate with each other to enable the focusing member 3 to stop at any height during rotation, thereby achieving different focusing effects. The first damping member 7, the second damping member 8, and the third damping member 9 may be rubber rings, silicone pads, friction washers, etc., and this is not limited by the present invention.

[0060] In summary, light emitted by light source assembly 4 passes through first optical element 5, undergoes preliminary color mixing, and then passes through second optical element 6 to further mix the undesirable light spots in the middle. Rotating second lamp body 2 synchronously rotates focusing element 3, which in turn drives second optical element 6 along its axis. Adjusting the distance between second optical element 6 and light source assembly 4 changes the angle of light emission, ultimately achieving the focusing function. Light-emitting elements with two or more colors can achieve different light mixing effects, and combined with the focusing structure, different light angle changes can be achieved.

[0061] The above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the preferred embodiments, it should be understood by those skilled in the art that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present invention.
