It should be understood that the present invention is capable of various variations in different embodiments without departing from the scope of the present invention, and that the descriptions and illustrations herein are intended to be illustrative in nature and not to limit the present invention.

These descriptions are appropriate when these elements are in the positions shown in the drawings. If the descriptions of the positions of these elements change, the indications of these directions will also change accordingly.

[0033] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of the technical features being referred to. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the described features. Throughout the description of this application, "plurality" means two or more, unless otherwise specifically defined.

[0034] See Figures 1 to 4 The fiber optic lamp 100 of the present application includes a light source component (not shown in the figure), a fiber optic lamp adapter structure 10, and a plurality of optical fibers 20. The light inlet end of the optical fiber 20 is connected to one end of the fiber optic lamp adapter structure 10 where the light outlet 13 is provided. The light source component is connected to one end of the fiber optic lamp adapter structure 10 where the light inlet 12 is provided. The light emitted by the light source component can pass through the fiber optic lamp adapter structure and be emitted from the light outlet ends of the plurality of optical fibers. For example, the light source component can be an LED light source. Among them, the LED light source can be a cold white light LED lamp bead, a warm white light LED lamp bead, or an RGB lamp bead. Alternatively, the LED light source is a combined light source formed by any combination of cold white light LED lamp bead, warm white light LED lamp bead, and RGB lamp bead. Alternatively, the light source component can be a COB light source. Alternatively, the light source component can be an incandescent lamp.

[0035] The fiber optic lamp 100 can be adapted to be provided with multiple fiber optic lamp adapter structures 10, each fiber optic lamp adapter structure 10 having a different number of light outlets 13. Users can select the corresponding fiber optic lamp adapter structure 10 to connect the light source and the optical fiber 20 according to their needs.

[0036] The fiber optic light adapter structure 10 includes an adapter base 1 and multiple luminous flux switch assemblies 2 mounted on the adapter base 1. The multiple luminous flux switch assemblies 2 can individually adjust the amount of light passing through each optical fiber 20, so that the brightness of the light emitted from different optical fibers 20 can vary, thereby meeting the brightness requirements of more scenarios and satisfying more user needs. For example, the fiber optic light 100 can be used in a jewelry display scenario to simultaneously illuminate multiple different pieces of jewelry. When the brightness of a particular piece of jewelry needs to be adjusted, the corresponding luminous flux switch assembly 2 can be used to adjust the brightness separately, rather than directly adjusting the brightness of the light source. The fiber optic light 100 of the present application can also be used in photography scenarios or other scenarios.

[0037] See Figure 5 and Figure 6 The interior of the adapter 1 is hollow to form a light cavity 11, one end of the adapter 1 forms a light inlet 12 connected to the light cavity 11, and the other end of the adapter 1 forms a plurality of light outlets 13 connected to the light cavity 11. The light cavity 11 forms a plurality of light passages 14 corresponding to the plurality of light outlets 13. The plurality of light passages 14 are independently provided and correspond one to one with the light outlets 13. Among them, one end of the adapter 1 provided with the light inlet 12 is used to connect with the light source component, and the light emitted by the light source component can be emitted into the light cavity 11 through the light inlet 12. The plurality of light outlets 13 are connected to a plurality of optical fibers 20 in a one-to-one correspondence, so that the light emitted by the light source component passes through the light cavity 11 and the light passages 14 and enters the optical fiber 20 connected to the light outlet 13, and is emitted from the light outlet end of the optical fiber 20.

[0038] The number of light channels 14 on the adapter 1 is adapted to the needs of the user and can be 2, 3, 4, or more. The multiple light channels 14 are evenly distributed at the end of the adapter 1 away from the light inlet 12, so that the light passing through the light cavity 11 is evenly entered into each optical fiber 20 connected to the light outlet 13.

[0039] Each optical fiber 20 includes a fiber body 201 and a light-inlet connector 202 disposed at one end of the fiber body 201. The light-inlet connector 202 passes through the light outlet 13 and plugs into the light passage 14 of the adapter 1, securing the optical fiber 20 to the adapter 1. Light passing through the adapter 1 sequentially passes through the light-inlet connector 202, the fiber body 201, and exits from the end remote from the light-inlet connector 202. In one embodiment, each optical fiber 20 includes a light-outlet connector 203 disposed at the other end of the fiber body 201. The light-outlet connector 203 is used to connect to lighting accessories and other lighting effects components.

[0040] In one embodiment, the light passage 14 is circular, and the axis of the optical fiber 20 coincides with the axis of the light passage 14. In other embodiments, the light passage 14 may also have other shapes, such as a hexagon, an octagon, or an ellipse. Preferably, the axes of the multiple light passages 14 intersect at the light source, allowing light emitted by the light source to be emitted directly from the light passage 14 without requiring a dimming structure to adjust the light emission angle of the light emitted by the light source.

[0041] Multiple luminous flux switch assemblies 2 are installed in the light cavity 11, and the multiple luminous flux switch assemblies 2 are arranged in a one-to-one correspondence with the positions of the light passages 14, so that the luminous flux switch assemblies 2 can respectively adjust the amount of light passing through different light passages 14. For example, the adapter 1 is provided with three light passages 14, and the adapter 1 is provided with a luminous flux switch assembly 2 corresponding to each light passage 14, that is, the adapter 1 is configured with three luminous flux switch assemblies 2. Therefore, by adjusting the corresponding luminous flux switch assembly 2, the amount of light passing through the corresponding light passage 14 can be adjusted. In other embodiments, the number of light passages 14 on the adapter 1 can be two, four, five, or more.

[0042] In one embodiment, the inner wall of the light passage 14 is adapted to the outer wall of the light-inlet connector 202, thereby achieving a snap connection between the light-inlet connector 202 and the adapter 1, thereby facilitating the connection between the optical fiber 20 and the adapter 1. In other embodiments, screw holes may be provided in the adapter 1, and bolts may be passed through the screw holes to secure the light-inlet connector 202 to the light outlet 13 of the adapter 1.

[0043] In one embodiment, the adapter 1 has a connecting portion at the light inlet 12, which can be connected to a power supply or other structures. The connecting portion can be a threaded structure or a snap-fit ​​structure.

[0044] See Figures 5 to 12 Each luminous flux switch assembly 2 includes a dial 21 and a plurality of paddles 22. The dial 21 is used to drive the paddles 22 to change the size of the through hole formed by the paddles 22 at the axis of the light passage 14, thereby changing the amount of light passing through the light passage 14, adjusting the amount of light entering the optical fiber 20, and further adjusting the brightness of the light emitted from the optical fiber 20.

[0045] Specifically, the dial 21 is annular and has an avoidance hole 211 formed inside for light to pass through; the dial 21 is rotatably connected to the adapter 1, and the dial 21 is located in the light cavity 11 near the light channel 14. The central axis of the dial 21 is coaxial with the axis of the light channel 14. The dial 21 can rotate around its own axis relative to the adapter 1, and the axis of the avoidance hole 211 is coaxial with the central axis of the dial 21.

[0046] In one embodiment, the adapter 1 has a dial mounting slot 141 formed in the light passage 14 near the light cavity 11, where the dial 21 is mounted. The inner diameter of the dial mounting slot 141 matches the diameter of the dial 21, and the dial 21 is mounted within the dial mounting slot 141. The diameter of the opening of the dial mounting slot 141 is slightly smaller than the diameter of the dial 21, so that after the dial 21 is pressed into the dial mounting slot 141, it is constrained within the dial mounting slot 141. The dial 21 can rotate about its own axis but cannot escape from the dial mounting slot 141, thereby achieving a rotational connection between the dial 21 and the adapter 1.

[0047] In other embodiments, the adapter 1 has a dial mounting slot 141 formed in the light passage 14 near the light cavity 11. The diameter of the dial mounting slot 141 matches the diameter of the dial 21, and the dial mounting slot 141 is used to mount the dial 21. After the dial 21 is mounted in the dial mounting slot 141, a retaining ring is fixed at the opening of the dial mounting slot 141 to prevent the dial 21 from disengaging from the dial mounting slot 141, thereby achieving a rotational connection between the dial 21 and the adapter 1. The retaining ring can be a snap ring structure that is snapped onto the adapter 1; or the retaining ring can be a rigid circular ring that is fixedly connected to the adapter 1 via screws.

[0048] The plurality of paddles 22 are movably connected to the dial 21 and the adapter 1, and when the dial 21 rotates around its axis, the dial 21 can drive all the paddles 22 to gather toward the central axis of the dial 21 or spread away from the central axis of the dial 21, so as to change the size of the through hole formed by the plurality of paddles 22 at the axis of the light passage 14, thereby changing the amount of light passing through the light passage 14, thereby adjusting the amount of light entering the optical fiber 20, and further adjusting the brightness of the light emitted from the optical fiber 20.

[0049] Among them, the axis of the dial 21 coincides with the axis of the light passage 14, and the movement direction of the paddle 22 is toward or away from the central axis of the dial 21. That is, when the size of the through hole formed by the multiple paddles 22 at the axis of the light passage 14 is changed, the axis of the through hole formed by the multiple paddles 22 always coincides with the axis of the light passage 14, so that the center of the light beam entering the optical fiber 20 always remains coincident with the axis of the light passage 14, making the light output effect of the optical fiber 20 more uniform.

[0050] In one embodiment, the adapter 1 is provided with a plurality of first mounting holes 15 on the radial outside of the light outlet 13, and the plurality of first mounting holes 15 are evenly distributed in a ring shape. The dial 21 is provided with a plurality of second mounting holes 212 in the shape of long strips on the radial outside of the avoidance hole 211, and the plurality of second mounting holes 212 are evenly distributed in a ring shape, and the length direction of the second mounting holes 212 extends along the radial direction of the dial 21, and the first mounting holes 15 and the second mounting holes 212 for connecting the same paddle 22 are staggered. A first connecting column 221 and a second connecting column 222 are provided on each paddle 22 at intervals. The first connecting column 221 is connected to the first mounting hole 15, and the second connecting column 222 is connected to the second mounting hole 212. In this arrangement, one end of the paddle 22 is rotatably connected to the adapter 1, and the other end of the paddle 22 can rotate relative to the dial 21 and move along the radial direction of the dial 21. When the dial 21 rotates, the dial 21 drives one end of the first connecting post 221 provided on the paddle 22 to rotate about the axis of the first mounting hole 15, causing the center of the paddle 22 to move toward or away from the central axis of the dial 21. The second mounting hole 212 is configured as an elongated strip, allowing the second connecting post 222 to move radially and rotate relative to the second mounting hole 212, thereby preventing mechanical interference that could cause the paddle 22 to become stuck. In other embodiments, the length of the second mounting hole 212 may also form an angle with the radial direction of the dial 21, with the ends of the length of the second mounting hole 212 spaced a certain distance apart from the radial direction of the dial 21.

[0051] In one embodiment, the structures of the first mounting hole 15 and the second mounting hole 212 are interchanged. That is, the first mounting hole 15 is configured as an elongated strip, while the second mounting hole 212 is configured as a circular hole. When the dial 21 rotates, the dial 21 drives one end of the second connecting post 222 provided on the paddle 22 to rotate about the axis of the second mounting hole 212, causing the center of the paddle 22 to move toward or away from the central axis of the dial 21. Furthermore, the first connecting post 221 can move radially and rotate relative to the first mounting hole 15, preventing mechanical interference that could cause the paddle 22 to become stuck.

[0052] In one embodiment, the positions of the first connecting post 221 and the first mounting hole 15 are interchanged, and the positions of the second connecting post 222 and the second mounting hole 212 are interchanged. That is, the first connecting post 221 is disposed outside the light outlet 13 of the adapter 1, the second connecting post 222 is disposed outside the avoidance hole 211 of the dial 21, and the first mounting hole 15 and the second mounting hole 212 are spaced apart on the paddle 22. In other embodiments, only the positions of the first connecting post 221 and the first mounting hole 15 may be interchanged, that is, the first connecting post 221 is disposed outside the light outlet 13 of the adapter 1, and the first mounting hole 15 is disposed on the paddle 22. Alternatively, only the positions of the second connecting post 222 and the second mounting hole 212 may be interchanged, that is, the second connecting post 222 is disposed outside the avoidance hole 211 of the dial 21, and the second mounting hole 212 is disposed on the paddle 22.

[0053] In one embodiment, a first connecting post 221 and a second connecting post 222 are respectively disposed on opposite sides of the paddle 22 along the axial direction of the dial 21. The dial 21 includes a first connecting portion rotatably connected to the adapter 1 and a second connecting portion for connecting to the paddle 22. The first connecting portion is disposed circumferentially outward from the second connecting portion and extends axially, resulting in a stepped cross-section of the dial 21. The paddle 22 is disposed within the concave portion defined by the first and second connecting portions. This increases the contact area between the dial 21 and the adapter 1 while ensuring sufficient space for the paddle 22, resulting in more stable rotation of the dial 21 and a more compact structure.

[0054] In one embodiment, among the multiple paddles 22 of each luminous flux switch assembly 2, two adjacent paddles 22 are arranged to overlap end to end, so that when the size of the dial 21 is fixed, the end of the paddle 22 that is slidably connected to the elongated second mounting hole 212 has a larger movable space, so that the luminous flux switch assembly 2 has a wider range of adjusting the amount of light passing through the light channel 14 and the structure is more compact.

[0055] The more the number of paddles 22, the closer the through hole formed by all the paddles 22 is to a circle, so that the light passing through the through hole formed by all the paddles 22 is more evenly irradiated on the center of the optical fiber 20, making the light output effect of the optical fiber 20 more uniform. However, the more the number of paddles 22, the more difficult it is to produce the luminous flux switch assembly 2, which leads to higher production costs. In the embodiment of the present application, the number of paddles 22 is preferably 4-12. Figure 11 In the embodiment shown, the number of the paddles 22 is 8. In other embodiments, the number of the paddles 22 can also be configured as 2, 3, or more than 12.

[0056] In one embodiment, the picks 22 are arc-shaped, with the concave side of the picks 22 facing the central axis of the dial 21 , so that the through hole formed by all the picks 22 is closer to a circle, making the light output effect of the optical fiber 20 more uniform.

[0057] In one embodiment, the luminous flux switch assembly 2 may not be provided with a dial 21. Instead, a gear may be provided at the position of the first connecting column 221 for the paddles 22. The multiple paddles 22 may be meshed with each other to achieve synchronized motion, so that all paddles 22 move toward or away from the central axis of the dial 21. Alternatively, a pulley may be provided at the position of the first connecting column 221 for the paddles 22. The multiple paddles 22 may be connected to the pulley via a timing belt to achieve synchronized motion. In other embodiments, the paddles 22 may be movably provided on the adapter 1 along the radial direction of the light passage 14. By withdrawing or inserting the paddles 22, the size of the through hole formed by the multiple paddles 22 at the axis of the light passage 14 can be changed, thereby varying the amount of light passing through the light passage 14.

[0058] See Figure 5 and Figure 6 The adapter 1 is provided with an arc-shaped lever movement groove 16, which connects the light-passing cavity 11 and the outside of the adapter 1. The plane where the lever movement groove 16 is located is perpendicular to the axis of the light-passing channel 14, and the central axis of the lever movement groove 16 coincides with the central axis of the dial 21. The luminous flux switch assembly 2 also includes a lever 23, which is connected to the dial 21, and one end of the lever 23 passes through the lever movement groove 16 to the outside of the adapter 1. The user can manually move the lever 23 on the outside of the adapter 1 to rotate the dial 21 around its own axis, thereby driving the paddle 22 to move toward or away from the central axis of the dial 21. In other embodiments, the luminous flux switch assembly 2 may not be provided with a lever 23, but may be driven to rotate by a motor connected to the dial 21.

[0059] In one embodiment, when the dial 21 rotates in a positive direction, the paddles 22 gather toward the axis of the light passage 14 . When the dial 21 rotates in a negative direction, the paddles 22 spread away from the axis of the light passage 14 .

[0060] A lever mounting hole is provided on the outer circumferential side of the dial 21. After the dial 21 is rotatably connected to the adapter 1, the lever 23 passes through the lever motion groove 16 from the outer side of the adapter 1 and connects to the lever mounting hole, thereby installing the lever 23. The lever 23 and the lever mounting hole can be connected by an interference fit, a threaded connection, or an adhesive connection.

[0061] See Figure 1 、 Figure 2 Already reached Figure 13 and Figure 14In one embodiment, the fiber optic lamp adapter structure 10 also includes a shell 3 and a reflector cup 4. The shell 3 is connected to the adapter seat 1 and is located on the side of the light cavity close to the light inlet 12. A receiving cavity is formed inside the shell 3, and the reflector cup 4 is arranged in the receiving cavity. A lamp holder connecting seat 41 is provided at the end of the reflector cup 4 facing away from the light inlet 12, and the light source component is connected to the lamp holder connecting seat 41. Among them, the light emitted by the light source component is divergent, and part of the light emitted by the light source component directly irradiates the light channel 14. Moreover, part of the light emitted by the light source component is reflected by the reflector cup 4 to the light channel 14, so that the light at the light channel 14 is more concentrated, thereby improving the light output effect of the lamp system. The connection between the light source component and the lamp holder connecting seat 41 can be a threaded connection or a snap connection.

The reflector cup 4 is threadedly connected to the end of the housing 3 facing away from the adapter 1. A lamp holder connection base 41 is disposed on the outer side of the end of the housing 3 facing away from the adapter 1. In this embodiment, the housing 3 and adapter 1 can also be connected via a snap-fit ​​connection.

[0063] In the embodiment, the lamp holder connection base 41 may also be provided on the housing 3. Alternatively, the optical fiber lamp adapter structure 10 is not provided with the housing 3, and the light source is connected to the adapter base 1 through the reflector cup 4.

[0064] In other embodiments, the light source may also be directly connected to the connecting portion of the adapter 1 .

[0065] The present application also provides a lighting system, including a lighting accessory and a fiber optic lamp 100. The lighting accessory is connected to the light-emitting connector 203 of the optical fiber 20 of the fiber optic lamp 100, so that the light from the light source is transmitted to the lighting accessory through the optical fiber 20. The number of lighting accessories is adapted to the number of optical fibers 20, that is, a plurality of lighting accessories are also configured, and the lighting effects of each lighting accessory can be the same or different. The light emitted by the light source passes through the fiber optic lamp adapter structure 10 and the optical fiber 20 and enters the lighting accessory, and displays the corresponding lighting effect through the lighting accessory. For example, the lighting accessory can be a standard photography cover, a softbox, a snoot, a softball, etc.

[0066] The fiber optic lamp adapter structure 10 includes an adapter seat 1 and a plurality of light flux switch components 2. The interior of the adapter seat 1 is hollow to form a light cavity 11, and one end of the adapter seat 1 forms a light inlet 12 connected to the light cavity 11, and the light source is connected to the light inlet 12. The other end of the adapter seat 1 is formed with a plurality of light outlets 13 connected to the light cavity 11. The light cavity 11 forms an independent light channel 14 corresponding to the light outlet 13, and the optical fiber 20 is connected to the light outlet 13; the plurality of light flux switch components 2 are connected to the light cavity The positions of the light channels 14 are arranged one by one; each light flux switch assembly 2 includes a plurality of paddles 22, which are movably connected to the adapter 1. The plurality of paddles 22 can converge toward the axis of the light channel 14 or spread away from the axis of the light channel 14 to change the size of the through hole formed by the plurality of paddles 22 at the axis of the light channel 14, thereby independently changing the amount of light in each light channel 14 to adjust the brightness of the light output of different optical fibers 20. Moreover, the movement direction of the paddles 22 is toward or away from the axis of the light channel 14, so that the axis of the through hole formed by the plurality of paddles 22 always coincides with the axis of the light channel 14, so that the center of the light beam entering the optical fiber 20 always coincides with the axis of the light channel 14, making the light output effect of the optical fiber 20 more uniform.
