This adjusts the distance between the second optical component and the first optical component, thus achieving the focusing process. Furthermore, by employing a secondary light mixing method, undesirable light spots during the initial light mixing process are reduced, improving the light output effect. Simultaneously, in conjunction with the focusing process, the angle of the illumination direction can be adjusted. Attached Figure Description

Detailed Implementation

[0033] To make the objectives, technical solutions, and advantages of this application clearer, the application will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0034] It should be noted that, in order to avoid obscuring this application with unnecessary details, only the structures and / or processing steps closely related to the solution of this application are shown in the accompanying drawings, while other details that are not closely related to this application are omitted.

[0035] Additionally, it should be noted that the terms “comprising,” “including,” or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such process, method, article, or apparatus.

[0036] Please refer to Figures 1 and 2, which show a preferred embodiment of the lamp 100 of this application. The lamp 100 includes a first lamp body 1, a second lamp body 2, a focusing component 3, a light source assembly 4, a first optical component 5, and a second optical component 6. This lamp 100 is a multi-color adjustable-focus lamp. Combining multi-color light sources with adjustable focus functionality, users can select the focus level of different light source colors as needed, thereby meeting the lighting requirements of various occasions.

[0037] 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 together form a connected inner cavity 11.

[0038] The focusing component 3 is located in the inner cavity 11. It can rotate and is fixed to the second lamp body 2, so that the focusing component 3 is relatively stationary relative to the second lamp body 2 in the direction of rotation of the second lamp body 2. That is to say, the focusing component 3 rotates synchronously with the second lamp body 2. The user only needs to rotate the second lamp body 2 to drive the focusing component 3 to rotate at the same time, thereby realizing the focusing operation. There is no need to directly operate the focusing component 3, which simplifies the operation process.

[0039] The focusing component 3 can move relative to the second lamp body 2 along an axis, which is the axis when the first lamp body 1 and the second lamp body 2 rotate coaxially. Referring to Figures 3 and 4, the inner wall of the inner cavity 11 at the second lamp body 2 is provided with a first positioning part 21, and the focusing component 3 is provided with a second positioning part 31 corresponding to the position of the first positioning part 21. One of the first positioning part 21 and the second positioning part 31 is a groove extending along the axis, and the other is a protrusion matching the groove. In this embodiment, the first positioning part 21 is a groove, and the second positioning part 31 is a protrusion that slides along the axis in the groove. The positioning snap-fit ​​connection between the first positioning part 21 and the second positioning part 31 is firm and reliable, ensuring the stability and accuracy of the focusing component 3 during rotation and avoiding inaccurate focusing due to loosening or misalignment.

[0040] The focusing component 3 is also threadedly engaged with the light source assembly 4. When the second lamp body 2 rotates relative to the first lamp body 1, it drives the focusing component 3 to rotate relative to the light source assembly 4 via the thread, so that the focusing component 3 can move relative to the light source assembly 4 along the axis. This threaded connection allows users to easily adjust the focal length of the light source when needed. By rotating the focusing component 3, the illumination distance and focusing effect of the light source can be precisely controlled to meet the lighting needs of different scenarios.

[0041] Specifically, as shown in Figure 5, 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 component 3 is provided with a second thread 32 corresponding to the first thread 411. The focusing component 3 is sleeved on the outside of the base 41, and the focusing component 3 and the base 41 are threadedly engaged by the first thread 411 and the second thread 32. The first thread 411 is a protruding ridge formed on the outer wall of the base 41 and spirally extending along the extension axis direction, and the second thread 32 is a groove formed on the inner wall of the focusing component 3 and spirally extending along the extension axis direction. Regardless of the position of the focusing component 3, a portion of it always overlaps with the base 41. The focusing component 3 and the base 41 are threadedly connected at their overlap, enabling a direct threaded connection between the focusing component 3 and the base 41. This allows the focusing component 3 to move relative to the light source assembly 4 in the direction of the extension axis, so that the second optical component 6 can move away from or closer to the light source assembly 4, achieving the focusing purpose. The structure is simple and the operation is convenient.

[0042] In other words, when the second lamp body 2 is rotated, the second lamp body 2 and the first lamp body 1 have the same axis of rotation. At this time, the focusing component 3 rotates synchronously with the second lamp body 2. Meanwhile, since the focusing component 3 is threadedly connected to the base 41, the focusing component 3 moves back and forth along the axis under the drive of the thread. At this time, the protrusion slides back and forth in the groove, so that the second optical component 6 moves along the axis relative to the light source assembly 4 and the first optical component 5 fixedly connected to the light source assembly 4, and finally adjusts the distance between the second optical component 6 and the light source assembly 4 to achieve focusing.

[0043] An anti-glare shield 22 is provided at the end of the second lamp body 2 furthest from the first lamp body 1, as shown in Figure 6. The anti-glare shield 22 includes a connecting end 221, a guide portion 222, and a limiting end 223 arranged sequentially. 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 into the second lamp body 2 and towards the second optical element 6. The limiting end 223 is connected to the guide portion 222 and extends towards 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 shield 22 effectively prevents light from directly shining into the eyes, reduces glare, and ensures that users will not feel glare or discomfort when using or viewing the light source.

[0044] Please refer to Figures 7 and 8. The second lamp body 2 also includes a limiting member 23, which comprises a first end 231 and a second end 232 disposed opposite to each other, and an annular peripheral wall 233 located between the first end 231 and the second end 232. The first end 231 is configured to engage with the limiting end 223. When the focusing member 3 moves to its maximum displacement, the first end 231 abuts against the limiting end 223 of the anti-glare cover 22, thereby limiting the focusing member 3 at its maximum displacement and preventing it from detaching from the second lamp body 2, greatly enhancing the safety and reliability of the lamp 100. The second end 232 is configured to abut against and fix the second optical element 6. The annular peripheral wall 233 has a first latching part 2341, and the focusing member 3 has a corresponding second latching part 33. The limiting member 23 and the focusing member 3 are locked together by the second latching part 33 and the first latching part 2341.

[0045] The focusing component 3 has a stepped portion 34. The second optical component 6 includes an optical portion 61 and an outer edge portion 62 surrounding the optical portion 61. The outer edge portion 62 is mounted on the stepped portion 34 and has several notches 621. The annular peripheral wall 233 of the limiting component 23 has an elastic arm 234. A first latching portion 2341 is provided on the elastic arm 234, and the free end 2342 of the elastic arm 234 extends beyond the second end 232. The second end 232 abuts against the end of the outer edge portion 62 that is away from the stepped portion 34. The free end 2342 extends into the notch 621 to limit and fix the second optical component 6 between the limiting component 23 and the focusing component 3.

[0046] In other words, the limiting component 23 simultaneously engages with both the focusing component 3 and the second optical component 6, locking all three together. This snap-fit ​​structure ensures a tight fit between the components, guaranteeing the stability of the second optical component 6 during focusing, preventing any shaking or shifting, thus ensuring focusing accuracy. The snap-fit ​​connection method also makes the installation and removal of the second optical component 6 simple and quick, requiring no additional tools or materials, reducing installation and maintenance costs.

[0047] Please refer to Figure 9. The light source assembly 4 is disposed within the inner cavity 11 and fixed to the first lamp body 1. It includes a base 41 and a light source substrate 42 disposed on the base 41. The base 41 is fixedly connected to the first lamp body 1, ensuring the stability of the light source assembly 4 and making the entire light source system more stable and less prone to shaking. The light source substrate 42 is provided with light-emitting elements of two or more colors, enabling the light source assembly 4 to emit light of multiple colors. By controlling the brightness and flashing frequency of different colored light-emitting elements, the overall tone and atmosphere of the light source can be easily adjusted to create different lighting effects.

[0048] Please refer to Figure 10. 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 that of the first light-emitting elements 4211. Furthermore, 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 distributed. The light-emitting elements with different color temperatures can provide more color choices, enabling the light source assembly 4 to emit light of multiple colors. The alternating arrangement helps to achieve uniform color mixing, produce gradients or specific light effects, and enhance visual appeal. This arrangement also allows for dynamic adjustment of the color temperature of the light source, thereby creating warm or cool environmental effects. In other embodiments, both the first light-emitting module 421 and the second light-emitting module 422 may include light-emitting elements with multiple color temperatures. For example, the first light-emitting module 421 may include red, yellow, and white light-emitting elements arranged in an array, and the second light-emitting module 422 may include uniformly distributed yellow and blue light-emitting elements. This application does not limit the color temperature of the light-emitting elements on the first light-emitting module 421 and the second light-emitting module 422, and the color temperature may be adjusted according to actual needs.

[0049] Furthermore, multiple light sources can be provided inside the cavity 11. In this embodiment, a common monochromatic light source is also provided above the light source substrate 42 to improve the lighting effect.

[0050] Please refer to Figure 10. The first optical element 5 and the second optical element 6 are sequentially arranged on the light emission path of the light source assembly 4. 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 from the light source assembly 4 undergoes preliminary optical processing, such as light homogenization and diffusion, firstly through the first optical element 5. The second optical element 6 is fixed to the focusing element 3, and under the influence of the focusing element 3, the second optical element 6 can move closer to or further away from the light source assembly 4 to further focus or diffuse the light, optimizing the light distribution and projection effect.

[0051] The first optical component 5 includes a reflector 51 and a light-mixing film 52. The reflector 51 is positioned on the outside of the light-emitting component, effectively reflecting and concentrating the light emitted by the light source assembly 4, maximizing the utilization of the light emitted by the light source, reducing light waste, and thus improving the lighting effect. The light-mixing film 52 covers the end of the reflector 51 furthest from the light-emitting component, and can perform secondary processing on the light, making the light more uniform and softer 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 can produce a uniform and soft light spot, making the lighting effect more natural and beautiful.

[0052] The second optical element 6 is a lens. The second optical element 6 has a minimum displacement and a maximum displacement relative to the light source assembly 4 in the axial direction of the rotation axis. That is, the second optical element 6 moves within a range of motion relative to the light source assembly 4 in the axial direction of the rotation axis. When the second optical element 6 moves along the extension axis to abut against the first optical element 5, the second optical element 6 is located at the minimum displacement. When the second optical element 6 moves along the extension axis to abut against the limiting end 223 of the focusing element 3, the second optical element 6 is located at the maximum displacement.

[0053] The displacement difference between the maximum and minimum displacement points is 12mm ± 0.5mm. The large focusing range allows the luminaire 100 to adapt to different application scenarios and lighting needs. Whether it is close-range zooming or long-range projection, it can be achieved by adjusting the position of the second optical element 6.

[0054] At the minimum displacement, the luminaire 100 has the maximum light emission angle, which is 55°±2°. At the maximum displacement, the luminaire 100 has the minimum light emission angle, which is 20°±2°. The beam angle of the luminaire 100 can be zoomed within this range, making it suitable for different scenarios and flexible in use.

[0055] The radial path of the light-emitting surface of the second optical element 6 extending radially from its center to its outer periphery is a non-uniform rational B-spline curve. The surface formed by rotating this curve around the axis of the second optical element 6 is a non-uniform rational B-spline surface.

[0056] Preferably, a first damping element 7 is provided between the outer surface of the base 41 and the inner surface of the focusing element 3, a second damping element 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 element 9 is provided between the outer surface of the focusing element 3 and the inner surface of the second lamp body 2. The first damping element 7, the second damping element 8, and the third damping element 9 cooperate with each other, so that the focusing element 3 can stop rotating at any height position at any time during rotation, so as to achieve the focusing effect under different needs. The first damping element 7, the second damping element 8, and the third damping element 9 can be rubber rings, silicone pads, friction pads, etc., and this application does not limit them.

[0057] In summary, the light emitted from the light source assembly 4 undergoes initial color mixing after being emitted through the first optical element 5, and then passes through the second optical element 6 to further mix the undesirable light spots in the middle section. The rotation of the second lamp body 2 synchronously drives the focusing element 3 to rotate, thereby causing the second optical element 6 to move along the axis. Adjusting the distance between the second optical element 6 and the light source assembly 4 achieves changes in the angle of light emission, ultimately realizing the focusing function. Using light-emitting elements of two or more colors can achieve different light mixing effects, and combined with the focusing structure, different light angle changes can be achieved.

[0058] The above embodiments are only used to illustrate the technical solutions of this application and are not intended to limit it. Although this application has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this application without departing from the spirit and scope of the technical solutions of this application.
