[0043] See also Figure 1 and Figure 2 As shown, the optical fiber lamp 10 according to the embodiment of the utility model comprises a lamp body 100, a connection cover 200 and a light guide optical fiber 300. The lamp body 100 is provided with a light source 110, and the lamp body 100 is provided with a light outlet 120 for the light source 110 to emit light outward. The connection cover 200 is connected to the lamp body 100 and covers the light outlet 120.

[0044] The light guide fiber 300 has a light inlet end 301 and a light outlet end 302, and the light inlet end 301 is fixedly mounted on the connection cover 200. The light inlet end 301 is opposite to the light outlet 120, so that the light emitted by the light source unit 110 can enter the light inlet end 301 of the light guide fiber 300. The light outlet end 302 is used to connect to an external lighting accessory.

[0045] The fiber optic lamp 10 of the embodiment of the utility model includes a lamp body 100, a connecting cover 200 and a light-guiding optical fiber 300. The connecting cover 200 is used to connect the light-guiding optical fiber 300 to the lamp body 100 so that the light emitted by the light source part 110 can enter the light inlet end 301 of the light-guiding optical fiber 300. The light output of the lamp body 100 can be extended by the light-guiding optical fiber 300 so that the light emitted by the lamp body 100 can illuminate some special areas. The light spot size of the light emitted by the lamp body 100 can be changed by the light-guiding optical fiber 300 without reducing the brightness of the light. Therefore, the fiber optic lamp 10 can flexibly change the light output direction, light output distance and angle, increase the modes and application scenarios of the photography light, help improve the shooting effect, and effectively enhance the user experience.

[0046] In addition, the light output of the lamp body 100 can be connected to other external light accessories through the light guide fiber 300 to obtain different required light effects and improve the photographic effect. Specifically, the light output end 302 of the light guide fiber 300 can be connected to an external light accessory. Among them, the external light accessory can be a standard photography cover, a soft light box, a snoot, a soft light ball, etc. Therefore, the light emitted by the lamp body 100 can be led out to various types of light accessories through the light guide fiber 300 to achieve different photographic light effects to meet different photography needs in different photography scenes.

[0047] In the embodiment of the present application, the lamp body 100 can be any type of photographic lamp, for example, a handheld photographic lamp, a photographic downlight, or the like.

[0048] like Figure 1 and Figure 3 As shown, the lamp body 100 may be generally cylindrical. The lamp body 100 may include a lamp housing 101, and the interior of the lamp housing 101 is hollow to accommodate the light source unit 110. A power supply unit 102 for supplying power to the light source unit 110 may also be provided inside the lamp housing 101. In addition, other components such as a main control board 103 and a heat dissipation structure 104 may also be provided inside the lamp housing 101, which is not limited in the present application.

[0049] The fiber optic lamp 10 of the present application may be provided with a control button 105, a power switch 106, etc. The control button 105 may be a parameter adjustment button capable of adjusting various lighting parameters such as the lighting mode, effect, brightness, etc. of the lamp body 100, and the present application does not limit this.

[0050] A wireless transmission module may be provided in the lamp body 100, and the wireless transmission module is used to connect to terminal devices such as mobile phones and computers. Users can also control various lighting parameters such as the lighting mode, effect, brightness, etc. of the lamp body 100 through mobile phone APP and other operations, and this application does not limit this.

[0051] like Figure 2 As shown, a light outlet 120 is opened at one end of the lamp housing, and the light source unit 110 is disposed in the lamp housing 101 close to the light outlet 120. The light emitted by the light source unit 110 can be emitted outward through the light outlet 120.

[0052] In the embodiment of the present application, the light source unit 110 can be a plurality of types of light sources. In one embodiment, the light source unit 110 can be an LED light source. Among them, the LED light source can be a cold white LED lamp bead, a warm white 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 LED lamp bead, warm white LED lamp bead and RGB lamp bead.

[0053] In one embodiment, the light source unit 110 may include an LED point light source. Specifically, the LED point light source may be a cold white light LED lamp bead, or a warm white light LED lamp bead, or an RGB lamp bead.

[0054] In one embodiment, the light source unit 110 may include a plurality of LED point light sources. Specifically, the plurality of LED point light sources may be a combination of at least one of cold white LED lamp beads, warm white LED lamp beads, and RGB lamp beads. In this embodiment, the distribution and arrangement of each lamp bead are not specifically limited, and each lamp bead may be arranged in a partition or mixed according to a certain rule as needed, depending on the specific situation.

[0055] In one embodiment, the light source unit 110 may be a pulse light source, wherein the pulse light source can emit pulse light, and may be a xenon lamp tube, a xenon flash lamp, or the like.

[0056] Alternatively, the light source unit 110 may be a COB light source. Alternatively, the light source unit 110 may be an incandescent lamp.

[0057] In the embodiment of the present application, the connection cover 200 is used to fix the light inlet end 301 of the light guide optical fiber 300 and connect the light guide optical fiber 300 to the lamp body 100. Figure 2 In one embodiment, a through hole 210 is provided through the connection cover 200, and the light inlet end 301 of the light guide optical fiber 300 is fixed in the through hole 210. For example, the diameter of the light guide optical fiber 300 can match the inner diameter of the through hole 210. When connecting, the light inlet end 301 of the light guide optical fiber 300 is directly inserted into the through hole 210 to achieve fixation.

[0058] In other embodiments, the light inlet end 301 of the light-guiding optical fiber 300 may be disposed in the through hole 210 through a fixed sleeve. The inner diameter of the fixed sleeve matches the diameter of the light-guiding optical fiber 300, and the outer diameter of the fixed sleeve matches the inner diameter of the through hole 210. When connected, the fixed sleeve is first sleeved on the light inlet end 301 of the light-guiding optical fiber 300, and then correspondingly inserted into the through hole 210, so that the light inlet end 301 of the light-guiding optical fiber 300 is fixedly connected to the through hole 210. By providing the fixed sleeve, the fixed sleeve can not only play the role of fixing the light-guiding optical fiber 300, but also protect the light inlet end 301 of the light-guiding optical fiber 300.

[0059] In the embodiment of the present application, the number of light-guiding optical fibers 300 connected to the lamp body 100 may be one or more. Figure 1 As shown, in one embodiment, the number of the light guide optical fiber 300 is one. The number of the through hole 210 on the connection cover 200 may be one.

[0060] like Figure 4As shown, in one embodiment, there are multiple light guide optical fibers 300. The lengths of the multiple light guide optical fibers 300 may be the same or different.

[0061] Correspondingly, if Figure 5 As shown, there are a plurality of through holes 210 on the connection cover 200 , and the light inlet ends 301 of the light-guiding optical fibers 300 are fixedly disposed in the through holes 210 in a one-to-one correspondence.

[0062] In the embodiment of the present application, the connection cover 200 may be a light shielding cover structure. In addition, the connection cover 200 is light-proof except for the through hole 210 connected to the light inlet end 301 of the light guide fiber 300. In this way, as much light as possible emitted by the lamp body 100 can enter the light inlet end 301 of the light guide fiber 300 and be transmitted to the light outlet end 302. Figure 2 As shown, a specific structure of the connection cover 200 is shown as a cover plate structure with a small arc, but the structure of the connection cover 200 is not limited thereto, and it can also be other structures. For example, the connection cover 200 can be a flat plate structure, a cone cover plate structure, a hemispherical cover plate structure, etc.

[0063] In the embodiment of the present application, the number of light guide fibers 300 connected to the lamp body 100 can be one or more, so that the light output of the lamp body 100 can be used one-to-one or one-to-many. For example, the light output of the lamp body 100 can be connected to one or more lighting accessories through the light guide fibers 300.

[0064] It should be noted that when the light source unit 110 is an LED point light source, the light output of the LED point light source may all enter one light guide fiber 300, so as to realize single light source light emission and single point light emission. Alternatively, the light output of the LED point light source may also enter multiple light guide fibers 300 at the same time, so as to realize single light source light emission and multi-point light emission.

[0065] When the light source unit 110 is a plurality of LED point light sources, the light emitted by the plurality of LED point light sources may all enter one light-guiding optical fiber 300 , thereby realizing multi-light source lighting and single-point light emission.

[0066] Alternatively, the light from multiple LED point light sources can also enter multiple light guide fibers 300 respectively, so as to realize multi-light source light emission and multi-point light emission. Among them, multiple LED point light sources and multiple light guide fibers 300 can be arranged in a one-to-one correspondence. Alternatively, multiple LED point light sources and multiple light guide fibers 300 can also be arranged in a one-to-many or many-to-many manner.

[0067] See also Figure 6As shown, in the embodiment of the present application, the light guide optical fiber 300 may include a core 310 and at least one cladding layer coated outside the core 310. The number of the cores 310 may be one or more. When the number of the cores 310 is one, the light guide optical fiber 300 is a single-core optical fiber. When the number of the cores 310 is multiple, the light guide optical fiber 300 is a multi-core optical fiber.

[0068] In the embodiment of the present application, the light-guiding optical fiber 300 is a single-core optical fiber or a multi-core optical fiber, which may be determined according to the specific situation.

[0069] In the embodiment of the present application, the core 310 of the light-guiding optical fiber 300 may be made of optical fiber materials such as quartz, glass, and plastic.

[0070] In the embodiment of the present application, the number of cladding layers can be one, or two or more. When there is one cladding layer, it is wrapped around the core 310 to form the light-guiding optical fiber 300. The cladding layer serves as both an optical reflection layer and a protective layer for the optical fiber to transmit light.

[0071] When there are multiple cladding layers, each cladding layer is sequentially wrapped around the outside of the fiber core 310. Figure 6 As shown, each cladding layer may be a first cladding layer 320, a second cladding layer 330 and a third cladding layer 340. The first cladding layer 320 is wrapped around the fiber core 310, and mainly serves as an optical reflective layer for optical fiber transmission light. The second cladding layer 330 is wrapped around the first cladding layer 320, and mainly serves as a buffer, protection, reinforcement, etc. The third cladding layer 340 is wrapped around the second cladding layer 330, and mainly serves as a buffer, protection, reinforcement, etc.

[0072] For example, the first coating layer 320 can be made of fluorine-doped quartz and other materials. The second coating layer 330 can be made of acrylic resin, silicone resin, ethylene-tetrafluoroethylene copolymer, polyurethane and polyimide and other materials. The second coating layer 330 can be made of acrylic resin, silicone resin, ethylene-tetrafluoroethylene copolymer, polyurethane and polyimide and other materials. This application does not make specific limitations on this.

[0073] In the embodiment of the present application, the light inlet end 301 of the light guide optical fiber 300 is connected to the lamp body 100 through the connection cover 200. Figure 2 In one embodiment, the connection cover 200 is detachably connected to the lamp body 100. Specifically, the lamp body 100 is provided with a connection slot 130, and the connection cover 200 is provided with a connection protrusion 220 corresponding to the connection slot 130, and the connection protrusion 220 can be inserted into the connection slot 130.

[0074] like Figure 7As shown, a plurality of connection blocks 141 are convexly provided on one end surface of the lamp body 100, and a connection slot 130 is provided on the connection block 141. The connection slot 130 may be an L-shaped slot. The connection slot 130 includes a first slot section 131 arranged along the axial direction of the lamp body 100, and a second slot section 132 vertically connected to one end of the first slot section 131.

[0075] Combination Figure 2 As shown, the connection protrusions 220 are arranged on the circumferential side wall of the connection cover 200 corresponding to each connection block 141. The width of the connection protrusions 220 matches the width of the first slot section 131. The thickness of the connection protrusions 220 matches the height of the second slot section 132. When the connection cover 200 is connected to the lamp body 100, the connection cover 200 is first moved axially along the lamp body 100 so that the connection protrusions 220 slide into the connection slots 130 along the first slot section 131, and then the connection cover 200 is rotated so that the connection protrusions 220 are clamped into the second slot section 132. Thus, a detachable fixed connection between the connection cover 200 and the lamp body 100 is achieved.

[0076] It can be understood that in some other embodiments, the positions of the connection slot 130 and the connection protrusion 220 can be interchanged. That is, the connection slot 130 is provided on the connection cover 200. The connection protrusion can be correspondingly provided on the lamp body 100.

[0077] In the embodiment of the present application, the connection cover 200 and the lamp body 100 are detachably connected by the engagement of the connection protrusion 220 with the connection slot 130. However, the present application is not limited thereto, and in some other embodiments, the connection cover 200 can also be detachably connected to the lamp body 100 by a magnetic attraction structure, a threaded locking structure, or a buckle structure.

[0078] Alternatively, in other embodiments, the connection cover 200 and the lamp body 100 may be an integral structure.

[0079] like Figure 3 As shown, in one embodiment, the lamp body 100 includes a connection seat 140, and the light outlet 120 is disposed through the connection seat 140. Specifically, the lamp housing 101 may be a hollow cylindrical structure with one end open. The connection seat 140 is disposed on the open end of the lamp housing 101, and the connection seat 140 may close the lamp housing 101 after the components inside the lamp housing 101 are installed. The connection seat 140 and the lamp housing 101 may be detachably connected. Alternatively, the connection seat 140 and the lamp housing 101 may be fixedly connected.

[0080] like Figure 3As shown, the connection cover 200 may be detachably connected to the connection base 140. For example, the connection slot 130 may be provided on the connection base 140. In the embodiment of the present application, the connection cover 200 can be connected to the lamp body 100 by connecting to the connection base 140. However, the present application is not limited thereto, and in other embodiments, the connection base 140 may be omitted, that is, the connection cover 200 is directly connected to the lamp housing 101.

[0081] like Figure 3 As shown, the light source 110 is disposed in the lamp housing 101 near the connection base 140 . The light outlet 120 may be disposed through the connection base 140 , and the light emitted by the light source 110 may enter the light guide fiber 300 through the light outlet 120 .

[0082] In the embodiment of the present application, when the light inlet end 301 of the light-guiding optical fiber 300 is fixed to the connection cover 200 and the connection cover 200 is connected to the lamp body 100, the light inlet end 301 of the light-guiding optical fiber 300 may or may not be in contact with the light source unit 110. The light source unit 110 may have a light-emitting surface. The light-emitting surface may be a single-point light-emitting surface formed by one LED point light source. Alternatively, the light-emitting surface may also be a multi-point light-emitting surface formed by a combination of multiple LED point light sources.

[0083] In one embodiment, the light-inlet end 301 of the light-guiding optical fiber 300 abuts against the light-emitting surface. For example, when the light-inlet end 301 of the light-guiding optical fiber 300 is inserted into the through hole 210 on the connection cover 200 for fixing, the light-inlet end 301 of the light-guiding optical fiber 300 can extend a certain distance toward the surface of the connection cover 200 opposite to the lamp body 100 until the light-inlet end 301 of the light-guiding optical fiber 300 abuts against the light source portion 110.

[0084] In another embodiment, the light inlet end 301 of the light-guiding optical fiber 300 is arranged spaced apart from the light-emitting surface. Figure 3 As shown, when the light inlet end 301 of the light-guiding optical fiber 300 is inserted into the through hole 210 on the connection cover 200 for fixing, the light inlet end 301 of the light-guiding optical fiber 300 can be flush with the surface of the connection cover 200 opposite to the lamp body 100. It can be understood that when the connection cover 200 is connected to the lamp body 100, the surface of the connection cover 200 opposite to the lamp body 100 will not fit tightly with the lamp body 100, but there will be a gap. Therefore, the light inlet end 301 of the light-guiding optical fiber 300 is arranged flush with the surface of the connection cover 200 opposite to the lamp body 100, so that the light inlet end 301 of the light-guiding optical fiber 300 and the light-emitting surface can be spaced from each other.

[0085] In one embodiment, an optical element is provided between the light input end of the light-guiding optical fiber 300 and the light source unit 110. The optical element may be a focusing lens, a light homogenizer, or a filter. For example, when the optical element is a focusing lens, the focusing lens can focus the light emitted by the light source unit 110, and then reflect it to the light input end 301 of the light-guiding optical fiber 300, thereby improving the utilization rate of the light emitted by the light source unit 110. For another example, when the optical element is a filter, the filter can absorb part of the light emitted by the light source unit 110, so that the light entering the light input end 301 of the light-guiding optical fiber 300 changes to meet different photography needs.

[0086] In this embodiment, by arranging optical elements between the light source unit 110 and the light input end 301 of the light-guiding optical fiber 300, the light emitted by the light source unit 110 can be changed as required and emitted through the light-guiding optical fiber 300, so that the fiber optic lamp 10 can meet different photography requirements.

[0087] Specifically, when the connection cover 200 is connected to the lamp body 100, there may be a gap between the two, and the gap may be used as an accommodation space for accommodating the optical element. Figure 3 As shown, in one embodiment, the connection cover 200 is connected to the connection seat 140, and a receiving cavity 400 is formed therebetween. The receiving cavity 400 is used to receive an optical element, and the light emitted by the light source unit 110 can enter the light inlet end 301 of the light guide optical fiber 300 through the optical element.

[0088] It can be understood that in other embodiments, the accommodating cavity 400 may also be directly formed between the end surface of the connecting cover 200 and the lamp housing 101 .

[0089] The optical element may be directly connected to the end face of the light inlet end 301 of the light-guiding optical fiber 300. In this case, the optical element may match the size of the end face of the light inlet end 301 of the light-guiding optical fiber 300.

[0090] Alternatively, the optical element may be disposed on and cover the light emitting surface of the light source unit 110 .
