[0031] See also Figures 1 to 5 In this embodiment, a fiber optic lamp 100 is provided, which includes a lamp body 10 and an optical fiber 20 connected to the lamp body 10 .

[0032] A light outlet 121 is disposed on the lamp body 10 , and a light source 1111 is disposed inside the lamp body 10 . Light emitted by the light source 1111 can be emitted from the light outlet 121 .

[0033] One end of the optical fiber 20 is connected to the light outlet 121 of the lamp body 10; the optical fiber 20 can transmit the light emitted by the light source 1111 from one end of the optical fiber 20 to the other end, and scatter the light on the extension path of the optical fiber 20, so that the optical fiber 20 emits light throughout, thereby achieving a uniform lighting effect. The overall structure is simple, easy to install, and highly flexible, and the optical fiber 20 emits light more uniformly throughout, which can be widely used in application scenarios such as festival decorations and lighting scenes.

[0034] In some embodiments, the optical fiber 20 can be a through-light emitting optical fiber 20, a side-light emitting optical fiber 20, or a full-body emitting optical fiber 20. These types of optical fibers 20 can emit light evenly throughout their entire length, providing a consistent lighting effect, and are suitable for decorative scenes that require overall uniform lighting.

[0035] See also Figure 1 and Figure 5In some embodiments, the optical fiber 20 includes a core 21 for light transmission, a cladding layer 22 wrapped around the core 21 , and a scattering core disposed in the cladding layer 22 .

[0036] The refractive index of the cladding layer 22 is less than that of the core 21, so that the light can be totally reflected in the core 21. There are multiple scattering cores, which are evenly arranged on the interface between the cladding layer 22 and the core 21, so that the light transmitted along the core 21 is scattered when passing through the scattering cores, so that the optical fiber 20 can emit light throughout its extension direction.

[0037] Specifically, the fiber core 21 can be made of a high refractive index material such as quartz, glass or polyester to ensure efficient transmission and low loss of light. The wrapping layer 22 can be made of a light-transmitting material with a low refractive index such as polystyrene or polycarbonate to enable total internal reflection of light in the fiber core 21 and reduce light leakage.

[0038] The material of the scattering core can be selected from tiny transparent particles or microcrystals with different refractive indices, and generally silica gel microbeads, alumina particles and the like are selected. These tiny scattering cores are evenly distributed on the interface between the wrapping layer 22 and the fiber core 21. When the light in the fiber core 21 is irradiated on the scattering cores, total reflection will no longer occur; part of the light will be scattered by the scattering cores and emitted from the side wall of the optical fiber 20, so as to ensure that the light can be evenly scattered during the propagation process in the optical fiber 20, and produce a full-body luminous effect to adapt to various decorative environments.

[0039] In some embodiments, the cross-section of the optical fiber 20 is circular, square, triangular, pentagonal, or heart-shaped, etc. Optical fibers 20 with various cross-sectional shapes can be used for decorative lighting to create different visual effects and atmospheres.

[0040] Among them, the heart-shaped optical fiber is particularly suitable for romantic and celebratory scenes, such as weddings, Valentine's Day, etc. Square and pentagonal optical fibers 20 are suitable for edge lighting of advertising light boxes due to their large surface area, making the advertising content more eye-catching. Triangle and pentagonal optical fibers can achieve unique light effects and are suitable for stage lighting applications to enhance the visual impact of stage performances.

[0041] In some embodiments, the lamp body 10 in this embodiment can be a columnar structure, and the lamp body 10 can be various lamps that can emit light, such as a flash light, a photographic light, a flashlight, etc., as long as it can emit light and inject light into the optical fiber 20.

[0042] See also Figure 3 and Figure 4 In some embodiments, the fiber optic lamp 100 may further include a light shielding cover 30 , which is used to connect the lamp body 10 and the optical fiber 20 and shield excess light emitted from the light outlet 121 of the lamp body 10 .

[0043] In some embodiments, the light shielding cover 30 is provided with one or more through holes 32, and an optical fiber 20 can be inserted into each through hole 32, so that the light-incoming end of the optical fiber 20 extends into the light shielding cover 30 and is fixedly connected to the light shielding cover 30. A mounting position is provided at one end of the lamp body 10, and the light outlet 121 of the lamp body 10 is located in the mounting position, and the light shielding cover 30 is detachably connected to the mounting position of the lamp body 10.

[0044] By fixing the optical fiber 20 to the light shielding cover 30, and then detachably connecting the light shielding cover 30 to the mounting position of the lamp body 10, the connection and removal speed of the optical fiber 20 and the lamp body 10 can be effectively improved, and the installation and removal of the optical fiber 20 is convenient.

[0045] In some embodiments, a plurality of optical fibers 20 may be connected to the light shielding cover 30, that is, a plurality of optical fibers 20 may be connected to the lamp body 10. The plurality of optical fibers 20 may extend in different directions to cover a larger lighting range. In addition, the plurality of optical fibers 20 may be arranged radially, annularly or linearly, or may be flexibly arranged according to actual needs to be suitable for different decorative environments. The connection of a plurality of optical fibers 20 to a lamp body 10 not only improves the flexibility of lighting, but also reduces the problem caused by the limited light color of a single optical fiber 20.

[0046] It is conceivable that in some other embodiments, the light-shielding cover 30 may not be used, and one or more separated light outlets 121 may be directly provided on the lamp body 10, and the light-incoming end of the optical fiber 20 may be directly fixed to the light outlet 121 of the lamp holder 111, and bonded or fastened to the side wall of the light outlet 121 to fix the optical fiber 20 to the lamp holder 111.

[0047] See also Figure 1 and Figure 4 In some embodiments, the lamp body 10 may include a main body portion 11 and a transition portion 12 .

[0048] The end surface of the main body 11 is provided with a light source 1111. One end of the adapter 12 is detachably connected to the main body 11, and an installation position is formed at one end of the adapter 12 away from the main body 11. The light outlet 121 is arranged through the installation position of the adapter 12 for connecting the light shielding cover 30.

[0049] The adapter part 12 and the main body 11 can be connected by screws. When the light shielding cover 30 of different sizes needs to be replaced, the adapter part 12 on the main body 11 needs to be replaced together so that the light shielding cover 30 of different sizes can be fixed to the lamp body 10.

[0050] It is conceivable that the adapter portion 12 and the main body portion 11 may also be an integrated structure, that is, the mounting position is directly set on the end surface of the lamp body 10 and then detachably connected to the light shielding cover 30 .

[0051] See also Figure 4 In some embodiments, a plurality of connection bosses 31 are provided on the peripheral side of the light shielding cover 30, and a plurality of connection blocks 122 are provided on the end surface of the adapter 12 facing the light shielding cover 30, and the plurality of connection blocks 122 enclose the installation position.

[0052] A connection slot 123 corresponding to the connection boss 31 is formed on the inner side wall of each connection block 122. The connection slot 123 includes an opening section 1231 extending along the axial direction of the adapter 12 and a locking section 1232 extending along the circumferential direction of the adapter 12. The opening section 1231 and the locking section 1232 are connected to each other to form an L shape.

[0053] The connecting boss 31 on the light shielding cover 30 can enter the installation position from the opening section 1231, and then rotate in the circumferential direction so that the connecting boss 31 on the light shielding cover 30 is inserted into the locking section 1232 to achieve the connection between the light shielding cover 30 and the lamp holder 111. The size of the locking section 1232 can match the size of the connecting boss 31, so that when the connecting boss 31 is in the locking section 1232, it can be fixed by interference fit. When it is necessary to remove the light shielding cover 30, the light shielding cover 30 can be rotated in the opposite direction with force to make the connecting boss 31 exit the locking section 1232 and move out of the opening section 1231, so that the adapter 12 of the light shielding cover 30 can be removed.

[0054] It is conceivable that in some other embodiments, the connection boss 31 on the light shielding cover 30 and the connection slot 123 of the adapter 12 can be interchanged. Of course, the light shielding cover 30 and the lamp body 10 can also be connected by magnetic attraction, buckle connection, screw locking, etc.

[0055] In some embodiments, an optical element may be disposed in the light outlet 121 of the adapter 12, and the optical element may be a focusing lens, through which the light passes and then enters the optical fiber 20. The focusing lens may focus the light emitted by the light source 1111, and change the incident angle of the light entering the light inlet end of the optical fiber 20, so that the incident angle of the light is greater than the critical angle of the optical fiber 20, so that the light can be totally reflected in the fiber core 21.

[0056] Of course, in some other embodiments, the optical element may also include an element for changing the light effect, such as a light homogenizer or a light filter.

[0057] See also Figure 1 and Figure 2In some embodiments, the main body 11 may include a lamp holder 111. A PCB circuit board 1112 is provided in the lamp holder 111, and the light source 1111 is integrated on the PCB circuit board 1112. A heat sink 1113 may also be provided on the rear side of the circuit board, and the heat sink 1113 may be a fan heat sink 1113 or a fin heat sink 1113, which can quickly dissipate the heat dissipated by the light source 1111 and the PCB circuit board 1112 into the air, so as to improve the service life of the lamp body 10.

[0058] In some embodiments, the light source 1111 in the lamp holder 111 may include one LED point light source 1111 or multiple LED point light sources 1111 , each LED point light source 1111 being able to emit light independently and being adjusted by a corresponding control circuit.

[0059] In some embodiments, each LED point light source 1111 may correspond to an optical fiber 20 to achieve precise light output and control. For example, one LED point light source 1111 may correspond to one optical fiber 20 that emits light throughout the body, ensuring that the light effect of each optical fiber 20 is individually controlled. Of course, one LED point light source 1111 may be connected to multiple optical fibers 20 that emit light throughout the body, achieving a wider range of lighting effects and saving electricity.

[0060] In some embodiments, each LED point light source 1111 can be a single-color temperature light source 1111, a dual-color temperature light source 1111, an RGB light source 1111 or a mixed light source 1111, so that each LED point light source 1111 can emit light of different colors, different color temperatures or different brightness under the control of a control signal.

[0061] Specifically: The monochromatic temperature light source 1111 emits light of a fixed color temperature, which is suitable for scenes that require stable lighting effects. The dual-color temperature light source 1111 can also switch between cold light and warm light to meet the lighting requirements of different time periods or scenes. The RGB light source 1111 can emit light of three basic colors: red, green, and blue, and generate a variety of colors by combining these three colors to achieve rich color effects. The mixed light source 1111 can include the above multiple LED point light sources 1111, so that it can switch freely between monochromatic temperature, dual-color temperature and RGB modes to achieve more flexible lighting effects.

[0062] When a plurality of different types of LED point light sources 1111 are provided in the lamp head 111, and each LED point light source 1111 corresponds to an optical fiber 20 that emits light throughout the lamp head 111, each optical fiber 20 on the lamp head 111 can emit light of different brightness, different colors, or different color temperatures. One lamp head 111 can make multiple optical fibers 20 emit different lighting effects, which greatly enhances the decorative effect of the fiber optic lamp 100.

[0063] In some embodiments, the main body 11 may further include a battery module 112, wherein a detachable battery 1121 is disposed in the battery module 112. The battery module 112 can be detachably connected to the lamp head 111, so that the battery 1121 in the battery module 112 can supply power to the light source 1111 in the lamp head 111.

[0064] In some embodiments, the main body 11 may further include a control module 113, which may be detachably connected to the battery module 112 or the lamp head 111. The control module 113 is further provided with a control button 1131, which may be electrically connected to the light source 1111, and the user may send a control signal through the multiple control buttons 1131 to control the light emitting parameters of the light source 1111 in the lamp head 111.

[0065] For example, the user can press the brightness adjustment button to increase or decrease the brightness of the light emitted by the light source 1111 to meet different lighting needs. The user can also use the color temperature adjustment button to adjust the color temperature of the light emitted by the lamp head 111. The user can also use the hue adjustment button to change the hue of the light emitted by the light source 1111, such as switching between red, green, blue (RGB) and other colors, or mixing multiple color effects to suit occasions such as photography and stage lighting that require rich light effects.

[0066] In some embodiments, each control button 1131 can control a corresponding LED point light source 1111 , so that one control button 1131 controls one optical fiber 20 to emit light, thereby achieving precise control over each optical fiber 20 .

[0067] In some embodiments, a power interface is provided on the control module 113 , and the power interface can be connected to an external mobile power source via a power cord so as to supply power to the lamp head 111 or charge the battery module 112 .

[0068] In some embodiments, the control box of the lamp body 10 is also provided with a wireless transmission module, which is electrically connected to the light source 1111; the wireless transmission module is used to receive control signals from an external mobile terminal and control the light source 1111 to emit different types of light according to the control signals.

[0069] Specifically, the wireless transmission module mainly includes a receiver and a controller, and the receiver can receive a control signal from an external mobile terminal. The external terminal device can be a remote terminal such as a smart phone or a tablet computer. When the receiver receives the control signal, it transmits the control signal to the controller, and the controller controls the light emitting parameters of the light source 1111 according to the control signal, thereby controlling the light emitting effect of the optical fiber 20.

[0070] The color, color temperature, brightness and other parameters of the light emitted by the light source 1111 can be precisely adjusted through a remote mobile terminal, thereby controlling the light emission effect of the optical fiber 20. The user does not need to directly touch the lamp body 10, and can achieve all-round control of the optical fiber lamp 100 through the mobile terminal, and the operation method is more convenient. In addition, the lighting system composed of multiple optical fiber lamps 100 can be centrally managed through a mobile terminal, which can improve the use efficiency and make it suitable for some large shopping malls, exhibitions, stages or photography places.

[0071] See also Figure 6 In some embodiments, two lamp bodies 10 may be provided, and the two ends of the optical fiber 20 are respectively connected to the light outlets 121 of the two lamp bodies 10 , so that the light emitted by the two lamp bodies 10 is emitted from the two ends of the optical fiber 20 .

[0072] Among them, light enters both ends of the optical fiber 20, which can effectively enhance the luminous brightness of the optical fiber 20; it can also prevent the problem of the brightness of the optical fiber 20 gradually weakening along its extension direction, so that the light output brightness of each section of the optical fiber 20 is relatively uniform, so as to better decorate shopping malls, exhibitions, stages or photography venues.

[0073] In summary, a fiber optic lamp 100 of the present embodiment includes a lamp body 10 and an optical fiber 20 connected to the lamp body 10. The optical fiber 20 can transmit the light emitted by the light source 1111 from one end of the optical fiber 20 to the other end, and scatter the light over the entire length of the optical fiber 20, so that the optical fiber 20 emits light throughout. The overall structure is simple, easy to install, and highly flexible, and the optical fiber 20 emits light more evenly throughout the body, and can be widely used in scenes such as festival decorations, so as to provide users with more convenient and diversified lighting solutions.
