Description

Technical Field

[0001] The utility model relates to the field of photographic equipment, in particular to a photographic panel lamp. Background Art

[0002] There are roughly two types of LED panel lights for photography and videography on the market. One type is a light panel made by welding an LED lamp array on a whole hard PCB board, and placing it in a metal or plastic lamp shell. This type of light occupies a large area when it is not in use; the other type is the so-called cloth light, which uses cloth as the base material, and fixes the LED light panel or light strip to the cloth base material through processes such as sewing and edging. Although the cloth light is flexible and easy to roll up and store due to the use of a cloth base material, it requires a complex bracket system to fix it on all sides so that it can be unfolded flatly. The bracket system occupies a large area when not in use, resulting in the LED panel light for photography and videography as a whole occupying a large area when it is not in use. Utility Model Content

[0003] The utility model aims to solve the problem that the existing LED panel light for video recording occupies a large area when it is folded up and not in use.

[0004] In order to solve the above technical problems, the utility model provides a photographic and video panel light, comprising a plurality of lamp bodies and connecting parts, wherein the plurality of lamp bodies are rotatably connected; each of the lamp bodies comprises a substrate, a light bar arranged on the substrate, and a bracket arranged on the substrate; the connecting part is connected between two adjacent lamp bodies; the two ends of the connecting part are respectively rotatably connected to the brackets on the two adjacent lamp bodies, so that the two adjacent lamp bodies can rotate relative to each other, and thereby the plurality of lamp bodies can rotate relative to each other to an unfolded state or a folded state.

[0005] In some solutions of the present application, a card slot is provided on the bracket, and the card slot extends along the length direction of the bracket. The side edge of the substrate is inserted from the notch of the card slot and is engaged in the card slot.

[0007] In some schemes of the present application, a mounting through hole is provided on the bracket, and the mounting through hole is arranged near the end of the bracket in the length direction; connecting holes are provided at both ends of the connecting piece in the length direction, and the positions of the two connecting holes correspond to the positions of the mounting through holes on the brackets on the two adjacent lamp bodies respectively; the rotating shaft is passed through the corresponding mounting through hole and the connecting hole, so that the connecting piece and the bracket can rotate around the axis of the rotating shaft.

[0008] In some schemes of the present application, a accommodating groove is provided on the bracket, and the accommodating groove is spaced apart from the card slot; the accommodating groove is arranged at the end face close to the length direction of the bracket; the two ends of the connecting member in the length direction respectively pass through the notches of the accommodating grooves of the two adjacent brackets and are connected to the corresponding accommodating grooves.

[0009] In some solutions of the present application, the bracket forms a transition surface at the notch of the accommodating groove, and the transition surface is an inclined surface or an arc surface.

[0010] In some schemes of the present application, a first limiting portion and a second limiting portion are formed on the bracket, and the first limiting portion and the second limiting portion are respectively located at the two ends of the slot of the card slot; when the connecting member rotates relative to the bracket until it abuts against the first limiting portions on the two adjacent brackets, the two adjacent lamp bodies rotate to the unfolded state; when the connecting member rotates relative to the bracket until it abuts against the second limiting portions on the two adjacent brackets, the two adjacent lamp bodies rotate to the folded state.

[0011] In some solutions of the present application, the brackets are fixed on a group of opposite sides of the substrate, and the brackets on the same side of two adjacent substrates are rotatably connected to the same connecting member.

[0012] In some solutions of the present application, the substrate is a hollow plate structure, a plurality of independent and spaced channels are formed inside the substrate, and at least one side surface of the substrate is a light-transmitting surface; there are multiple light strips, the length direction of the light strips is the same as the length direction of the channels, and the multiple light strips are respectively placed in the multiple channels; and the light-emitting surface of the light strips faces the light-transmitting surface.

[0013] In some solutions of the present application, the light bar is fixedly connected to the outer surface of the substrate, and the light-emitting surface of the light bar faces the side away from the substrate; the substrate is a hollow plate structure or a solid plate structure.

In addition, the two adjacent lamp bodies are rotatably connected to the connecting part through the bracket, so that the relative rotation between the two adjacent lamp bodies is achieved, making the connection structure simple.

[0036] Typical embodiments that embody the features and advantages of the present invention will be described in detail in the following description. 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.

[0038] 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.

[0039] See Figures 1 to 7 A photographic video panel light is used to fill in the light for photographing objects or scenes to improve the shooting effect. The photographic video panel light includes a plurality of lamp bodies 1 and a connecting member 2. Each lamp body 1 includes a substrate 11, a light bar 12 provided on the substrate 11, and a bracket 13 provided on the substrate 11. The two ends of the connecting member 2 are rotatably connected to the brackets 13 on the two adjacent lamp bodies 1, respectively, to achieve a rotatable connection between the two adjacent lamp bodies 1, thereby enabling the plurality of lamp bodies 1 to rotate relative to each other to an unfolded state, thereby enabling the photographic video panel light to have a larger light-emitting area. The plurality of lamp bodies 1 can also rotate relative to each other to a folded state, thereby enabling the photographic video panel light to have a smaller storage volume. Therefore, the photographic video panel light occupies a small area when stored and is convenient for users to carry and transport.

[0040] See Figure 8 and Figure 9The photography and video panel light can be externally connected to the controller 7, or the photography and video panel light can be integrated with the controller 7. The controller 7 can be arranged on the outside of the substrate 11, fixed to the side of the substrate 11 away from the light-emitting surface of the light bar 12, or arranged on the edge of the substrate 11 facing the light-emitting surface of the light bar 12. Multiple light bars 12 are electrically connected to the controller 7 through conductive wires 8, so that the operating parameters of all light bars 12 can be controlled by the controller 7. The operating parameters include one or more of brightness, color temperature and lighting mode. The lighting mode can be a long-light mode or a marquee mode. The conductive wire 8 can be set at the edge of the substrate 11 or arranged on the side of the substrate 11 away from the light-emitting surface of the light bar 12.

[0041] In one embodiment, the controller 7 is provided with a wireless connection module that can be electrically connected to a control terminal, allowing the operating parameters of the light bar 12 to be adjusted via the control terminal. The wireless connection module can be a Wi-Fi module or a Bluetooth module. The control terminal can be a console, a mobile phone, a computer, etc.

[0042] In one embodiment, the controller 7 is provided with buttons, and the user can adjust the working parameters of the light bar 12 through the buttons.

[0043] See Figures 1 to 5 In one embodiment, the substrate 11 is rectangular, and brackets 13 are fixed on a set of opposite sides of the substrate 11. The brackets 13 on the same side of two adjacent substrates 11 are rotatably connected to the same connecting member 2. Figure 1 As shown, brackets 13 are connected to both the upper and lower sides of the substrate 11. Furthermore, the upper sides of two adjacent substrates 11 are rotatably connected to the same connector 2, and the lower sides of two adjacent substrates 11 are also rotatably connected to the same connector 2. This provides two rotatable connection locations between the two adjacent substrates 11, thereby improving the connection reliability between the two adjacent substrates 11. In other embodiments, brackets 13 may be fixed to only one side of the substrate 11 or at any position between a pair of opposite sides. For example, brackets 13 may be connected only to the upper side of the substrate 11; or only to the lower side of the substrate 11; or between the upper and lower sides of the substrate 11.

[0044] exist Figure 1 In the illustrated embodiment, the bracket 13 is elongated. When two adjacent substrates 11 are deployed, they are arranged along the length of the bracket 13, and the brackets 13 on the same side of the two adjacent substrates 11 are aligned. The sides of the two adjacent substrates 11 are aligned, and the bracket 13 is absent, improving the integrity of the light-emitting surface of the camera panel light.

[0045] See Figure 2 、 Figure 10 as well as Figure 11 The bracket 13 is provided with a slot 131. The extension direction of the slot 131 is consistent with the length direction of the bracket 13. The notch of the slot 131 is located on a side surface close to the substrate 11, and the slot openings of the two brackets 13 connected to the same substrate 11 are close to each other. For example, the bracket 13 extends horizontally, that is, the length direction of the bracket 13 is consistent with the horizontal direction. The notch of the slot 131 on the bracket 13 located at the upper side of the substrate 11 is located on the lower side of the bracket 13, and the notch of the slot 131 on the bracket 13 located at the lower side of the substrate 11 is located on the upper side of the bracket 13. The side edge of the substrate 11 is inserted through the notch of the slot 131 and is engaged in the slot 131, so that the bracket 13 wraps around a group of side edges of the substrate 11. That is, the bracket 13 forms an edge structure of the substrate 11, which plays a protective role for the substrate 11.

[0046] Bracket 13 is a profiled side bar, such as an aluminum profile, an aluminum alloy profile, or an iron profile. Bracket 13 is preferably an aluminum profile or aluminum alloy profile. This provides a greater load-bearing capacity, thereby increasing the strength of the lamp body 1. Furthermore, this reduces the weight of bracket 13, thereby reducing the overall weight of the camera panel light. It should be noted that bracket 13 can also be constructed of plastic or carbon fiber.

[0047] The side surfaces of the base plate 11 are flush with the longitudinal end surfaces of the bracket 13, allowing the bracket 13 to protect the entire corresponding side edge of the base plate 11. When two adjacent lamp bodies 1 are in the deployed state, the end surfaces of the brackets 13 on the two adjacent base plates 11 align, so that the side surfaces of the two adjacent base plates 11 align, making the light output surface of the photographic panel light more complete. In other embodiments, the side surfaces of the base plates 11 can also be located outside the longitudinal end surfaces of the bracket 13, and the length of the connector 2 can be designed so that when two adjacent lamp bodies 1 are in the deployed state, the adjacent side surfaces of the two adjacent base plates 11 align.

[0048] Specifically, the slots 131 are open at both ends of the bracket 13 in the longitudinal direction, so that the substrate 11 can be inserted into the slots 131 without providing a notch at the edge of the substrate 11. The side surfaces of the substrate 11 are flush with the longitudinal end surfaces of the bracket 13, which further simplifies the structure of the connection between the bracket 13 and the substrate 11. In other embodiments, the bracket 13 may not be provided with the slots 131, and the bracket 13 may be fixed to the outer surface of the edge of the substrate 11 by gluing or screwing.

[0049] See Figures 1 to 6The photographic panel light further includes a rotating shaft 3, connected to each end of the connecting member 2 in the longitudinal direction. The axis of the rotating shaft 3 is perpendicular to the longitudinal direction of the bracket 13. The two ends of the connecting member 2 in the longitudinal direction are rotatably connected to the brackets 13 on two adjacent lamp bodies 1 via the rotating shaft 3. In other words, each connecting member 2 is connected to two rotating shafts 3, one connected to each end of the connecting member 2 in the longitudinal direction. The axes of the two rotating shafts 3 are arranged in parallel and perpendicular to the longitudinal direction of the bracket 13. The brackets 13 on two adjacent lamp bodies 1 are respectively connected to the two rotating shafts 3, so that the brackets 13 on the two adjacent lamp bodies 1 can rotate relative to the connecting member 2 around the axis of the rotating shaft 3.

[0050] Specifically, each bracket 13 has a mounting hole 133 located near the end of the bracket 13 in its longitudinal direction. Each connector 2 has a connecting hole 21 at both ends of its longitudinal direction, and the positions of the two connecting holes 21 correspond to the positions of the mounting holes 133 on the brackets 13 of two adjacent lamp bodies 1. The rotating shaft 3 passes through the corresponding mounting holes 133 and connecting holes 21, allowing the connector 2 and bracket 13 to rotate about the axis of the rotating shaft 3. The rotating shaft 3 can be fixedly connected to the connector 2 and rotationally connected to the bracket 13; alternatively, the rotating shaft 3 can be rotationally connected to the connector 2 and fixedly connected to the bracket 13.

[0051] exist Figure 2 In the illustrated embodiment, the connection hole 21 is internally threaded, and the rotating shaft 3 is a bolt. The rotating shaft 3 passes through the corresponding mounting through-hole 133 and is threadedly connected to the connecting hole 21, thereby achieving installation of the rotating shaft 3 and realizing a rotational connection between the bracket 13 and the connecting member 2, thereby facilitating connection and simplifying the structure. In other embodiments, the rotating shaft 3 is threadedly connected to the mounting through-hole 133 of the bracket 13, and the rotating shaft 3 is inserted into the connecting hole 21 of the connecting member 2, thereby achieving a rotational connection between the bracket 13 and the connecting member 2.

[0052] See Figure 11 The bracket 13 is provided with a receiving groove 132, which is spaced apart from the card groove 131; the receiving groove 132 is provided at the end face of the bracket 13 in the length direction, and the two ends of the connecting member 2 in the length direction respectively pass through the notches of the receiving grooves 132 of the two adjacent brackets 13 and are connected to the receiving grooves 132 of the two adjacent brackets 13, so that the two ends of the connecting member 2 are respectively accommodated in the receiving grooves 132 of the two adjacent brackets 13. Among them, the connecting member 2 can rotate around the axis of the rotating shaft in the receiving groove 132, so that the two adjacent lamp bodies 1 can swing between the unfolded state and the folded state. Moreover, when the two adjacent lamp bodies 1 are in the unfolded state, the two ends of the connecting member 2 in the length direction are respectively located in the receiving grooves 132 of the brackets 13 of the two adjacent lamp bodies 1, thereby making the outer surface of the photographic and video panel lamp smoother and more beautiful.

[0053] exist Figure 11 In the illustrated embodiment, the cross-section of the bracket 13 is rectangular. Among the four circumferential side surfaces of the bracket 13, two adjacent side surfaces are respectively the first side surface 135 and the second side surface 136. That is, the first side surface 135, the second side surface 136, and the end surface of the bracket 13 in the longitudinal direction are all adjacent surfaces. The notch of the card slot 131 is located on the first side surface 135. The notch of the accommodating groove 132 is located on the end surface of the bracket 13 in the longitudinal direction and the second side surface 136. When two adjacent lamp bodies 1 are in the unfolded state, the connecting member 2 extends from the end surface of the bracket 13 in the longitudinal direction. When two adjacent lamp bodies 1 are in the folded state, the connecting member 2 extends from the second side surface 136 of the bracket 13.

[0054] See Figure 2 and Figure 6 The bracket 13 has a transition surface 134 formed at the notch of the accommodating groove 132, that is, the bracket 13 has a transition surface 134 formed between the second side surface 136 and the end surface of the bracket 13 in the longitudinal direction. The transition surface 134 is formed by cutting away part of the material at the intersection of the end surface of the bracket 13 in the longitudinal direction and the second side surface 136. The transition surface 134 is used to avoid mechanical interference when two adjacent brackets 13 rotate relative to each other.

[0055] In one specific embodiment, the transition surface 134 is an arc-shaped surface. The central axis of the transition surface 134 coincides with the axis of the rotating shaft 3 connected to the bracket 13 on which the transition surface 134 is provided. The distance between the rotating shaft 3 and the transition surface 134 is less than or equal to the distance between the rotating shaft 3 and the end surface of the bracket 13. The length of the connector 2 is twice the distance between the rotating shaft 3 and the end surface of the bracket 13. This ensures that when two adjacent lamp bodies 1 are rotated to the deployed state, the end surfaces of the two brackets 13 connected by the same connector 2 align, thereby causing the side surfaces of the substrates 11 of the two adjacent lamp bodies 1 to align. In other words, when the camera board light is deployed, no gap exists between the substrates 11 of the two adjacent lamp bodies 1. In this embodiment, when the camera board light is deployed, the connector 2 is completely located within the receiving grooves 132 of the two adjacent brackets 13, enhancing the overall aesthetics of the camera board light. In other implementations, the length of the connecting member 2 may also be greater than twice the distance between the rotating shaft 3 and the end surface of the bracket 13 , the transition surface 134 on the bracket 13 may be an inclined surface, or the transition surface 134 may not be provided on the bracket 13 .

[0056] exist Figure 2 In the embodiment shown, the distance between the rotating shaft 3 and the transition surface 134 is equal to the distance between the rotating shaft 3 and the end face of the bracket 13 in the length direction, so that the two brackets 13 connected to the same connecting member 2 can rotate relative to each other, while the force strength of the bracket 13 at the edge of the mounting through hole 133 is guaranteed to the greatest extent.

[0057] In one embodiment, the bracket 13 is provided with a first stopper and a second stopper, respectively disposed at opposite ends of the slot 131. When the connector 2 rotates relative to the bracket 13 until the first stopper on each of the two adjacent brackets 13 abuts, and the two adjacent lamp bodies 1 rotate to the unfolded state, the connector 2 and the two adjacent brackets 13 are aligned. When the connector 2 rotates relative to the bracket 13 until the second stopper on each of the two adjacent brackets 13 abuts, and the two adjacent lamp bodies 1 rotate to the folded state, the second side surfaces 136 of the two adjacent brackets 13 are aligned.

[0058] exist Figure 1 In the illustrated embodiment, when the connector 2 is rotated relative to the bracket 13 to the unfolded state, the two lamp bodies 1 are precisely aligned. That is, when the camera board light switches from the folded state to the unfolded state, the adjacent lamp bodies 1 rotate 180 degrees in the forward direction about the rotation axis 3, so that the two lamp bodies 1 are precisely aligned. When the camera board light switches from the unfolded state to the folded state, the adjacent lamp bodies 1 rotate 180 degrees in the reverse direction about the rotation axis 3, so that the two lamp bodies 1 are precisely stacked.

[0059] It should be noted that two adjacent lamp bodies 1 can also be rotated around the rotation axis 3 to any position between the folded state and the unfolded state, such as Figure 13 and Figure 14 For example: 90 degrees, 120 degrees, 135 degrees or 150 degrees. The user can adjust the angle between two adjacent lamp bodies 1 according to actual needs.

[0060] The bracket 13 has a first sidewall 1321 and a second sidewall 1322 formed within the receiving groove 132. The first sidewall 1321 and the second sidewall 1322 are arranged at an angle, parallel to the axis of the rotating shaft 3, and the plane of the first sidewall 1321 is parallel to the length of the bracket 13, while the plane of the second sidewall 1322 is perpendicular to the length of the bracket 13. Both ends of the connector 2 can rotate 90 degrees relative to the corresponding bracket 13, and the rotation direction is the same, allowing the two brackets 13 connected by the same connector 2 to rotate 180 degrees relative to each other. This allows two adjacent lamp bodies 1 to rotate 180 degrees about the rotating shaft 3, switching between an expanded and folded state. Therefore, when the connector 2 rotates relative to the bracket 13 to the expanded state, one side of the connector 2 abuts against the first sidewall 1321, placing the two lamp bodies 1 on the same plane. When the connector 2 is rotated relative to the bracket 13 to a folded state, one side of the connector 2 abuts against the second side wall 1322. At this point, the two lamp bodies 1 are exactly in a stacked position. That is, the first side wall 1321 of the bracket 13 forms a first limiter, and the second side wall 1322 of the bracket 13 forms a second limiter. The sides of the connector 2 that abut against the first side wall 1321 and the second side wall 1322, respectively, constitute a set of opposing faces of the connector 2. It should be noted that when the connector 2 is rotated relative to the bracket 13 to an unfolded state, the two lamp bodies 1 can also be exactly at a set angle, for example, 90 degrees, 120 degrees, or 160 degrees.

[0061] See Figure 15 and Figure 16 The base plate 11 is rigid and capable of supporting the light bar 12, eliminating the need for a separate support frame. Made of plastic, carbon fiber, or glass, the base plate 11 is lightweight, and thus the overall weight of the camera panel light, making it easier for users to carry and transport. Furthermore, the plastic, carbon fiber, and glass panels are inexpensive, reducing the cost of the camera panel light.

[0062] See Figure 12 and Figures 15 to 17In one embodiment, the interior of the base plate 11 is provided with a plurality of spaced channels 114, and the light bar 12 is disposed within the channels 114. The base plate 11 has a certain thickness to ensure its strength and prevent bending, which could affect the flatness of the camera panel light. The channels 114 within the base plate 11 create a hollow plate structure. For example, the base plate 11 may be a hollow polycarbonate plate, a hollow plate made of a plastic such as polyester or polypropylene, or a hollow glass plate. Compared to a solid plate, the hollow plate structure of the base plate 11 not only ensures its strength but also reduces its weight, making it easier for users to carry the camera panel light. Furthermore, the material required to produce the base plate 11 is reduced, lowering the cost of the base plate 11 and, consequently, the production cost of the camera panel light.

[0063] The multiple channels 114 all extend in the same direction, and each channel 114 is independently provided, allowing the substrate 11 to be integrally injection molded, thereby facilitating production of the substrate 11 and reducing production costs. Alternatively, the substrate 11 can be formed by drilling holes through a solid plate. Multiple channels 114 can be drilled through the solid plate in a single positioning operation, further facilitating production of the substrate 11 and reducing production costs.

[0064] In one embodiment, the channel 114 is a structure with both ends open and a hollow interior, that is, each channel 114 passes through both ends of the substrate 11, so that in addition to being produced by integral injection molding and by drilling holes through a solid plate, the substrate 11 can also be produced by extrusion molding using an extruder, which makes the production of the substrate 11 simpler and reduces production costs. Moreover, on the basis of ensuring the stress strength of the substrate 11, the length of the channel 114 is increased relative to the blind hole structure of the channel 114, further reducing the material required to produce the substrate 11 and reducing the cost of the substrate 11.

[0065] The base plate 11 includes a first side plate 111, a second side plate 112, and a plurality of partitions 113. The first side plate 111 and the second side plate 112 are arranged side by side, and the first side plate 111 and the second side plate 112 form two opposing side surfaces of the base plate 11 in the thickness direction. The partitions 113 are arranged between the first side plate 111 and the second side plate 112 and connected to the first side plate 111 and the second side plate 112, so that the first side plate 111 and the second side plate 112 are separated to form a plurality of channels 114 for mounting the light bar 12. Preferably, the first side plate 111, the second side plate 112, and the plurality of partitions 113 are an integrally molded structure, so that the base plate 11 can be produced by integral injection molding, by drilling holes through a solid plate, or by extrusion molding using an extruder, which simplifies the production of the base plate 11 and reduces production costs. Among them, multiple light strips 12 are correspondingly installed in multiple channels 114, so that the channels 114 of the substrate 11 provide installation space for the light strips 12, and the outer surface of the substrate 11 effectively protects the light strips 12, reducing the overall volume of the photographic panel light.

[0066] In other embodiments, the first side panel 111, the second side panel 112, and the plurality of partitions 113 together form a channel 114, and the plurality of light strips 12 are installed in the same channel 114. In other embodiments, the first side panel 111, the second side panel 112, and the partitions 113 may be separate structures, and the first side panel 111, the second side panel 112, and the partitions 113 may be fixed together by gluing, riveting, or heat pressing.

[0067] At least one of the first side panel 111 and the second side panel 112 is a light-transmitting structure to form a light-transmitting surface for light output from the light bar 12, so that the light generated by the light bar 12 can be emitted through the light-transmitting surface to the external object or scene being photographed. For example, the first side panel 111 is a light-transmitting structure, and the second side panel 112 and the partition 113 are light-opaque structures; alternatively, the first side panel 111 and the second side panel 112 are light-transmitting structures, and the partition 113 is light-opaque structure; or alternatively, the first side panel 111, the second side panel 112, and the partition 113 are all light-transmitting structures.

[0068] In one embodiment, the first side panel 111 is a light-transmitting structure, and the light-emitting surface of the light bar 12 faces the first side panel 111, so that the light emitted by the light bar 12 passes through the first side panel 111 and illuminates one side of the substrate 11, forming a single-sided light-emitting structure. In this embodiment, the second side panel 112 and the partition 113 can be a light-transmitting structure or an opaque structure.

[0069] like Figure 16As shown, in this embodiment, a reflective layer 6 is provided on the second side panel 112 or the partition 113, or both the second side panel 112 and the partition 113. The reflective layer 6 can reflect light emitted by the light bar 12 toward the light-emitting side of the substrate 11, thereby improving the light output effect of the photographic and video panel light. The reflective layer 6 can be a reflective coating layer sprayed on the second side panel 112 and the partition 113, or a reflective film affixed to the second side panel 112. It should be noted that the reflective layer 6 can also be omitted from the second side panel 112 or the partition 113.

[0070] In one embodiment, both the first side panel 111 and the second side panel 112 are light-transmitting structures, and the light bar 12 includes a first light bar 123 and a second light bar 124. The light-emitting surface of the first light bar 123 faces the first side panel 111, and the light-emitting surface of the second light bar 124 faces the second side panel 112. This allows light emitted by the first light bar 123 to pass through the first side panel 111 to illuminate the exterior of the substrate 11, and light emitted by the second light bar 124 to pass through the second side panel 112 to illuminate the exterior of the substrate 11, thereby forming a double-sided light-emitting structure. In this embodiment, the partition 113 can be a light-transmitting structure or an opaque structure.

[0071] In one embodiment of the present application, substrate 11 is a transparent structure, which provides good light transmission. In other embodiments, substrate 11 may be a light-transmitting but non-transparent structure. Alternatively, substrate 11 may be a light-transmitting structure of a corresponding color, depending on the desired lighting effect.

[0072] In one embodiment, a protective film 5 is provided on the light emitting surface side of the light bar 12 of the substrate 11; the protective film 5 protects the outer surface of the substrate 11 used for light emission, preventing the outer surface of the substrate 11 used for light emission from being scratched and affecting the light emission effect of the photographic panel light.

[0073] In one embodiment, the substrate 11 is provided with an optical structure layer 4 on the light-emitting side of the light bar 12. The optical structure layer 4 is used to adjust the illumination effect of the light emitted by the light bar 12. For example, the optical structure layer 4 can be a brightness enhancement film, which is affixed to the light-emitting side of the substrate 11 to increase the brightness of the light emitted by the photographic panel light. For another example, the optical structure layer 4 can be a soft light film, which is affixed to the light-emitting side of the substrate 11 to change the softness of the light emitted by the photographic panel light. In other embodiments, the optical structure layer 4 can also be an optical coating formed on the surface of the substrate 11 by spraying.

[0074] In one embodiment, if Figure 16As shown, the substrate 11 is provided with both an optical structure layer 4 and a protective film 5 on the light-emitting surface side of the light bar 12. The optical structure layer 4 is provided between the protective film 5 and the substrate 11, that is, the protective film 5 is provided on the outside of the optical structure layer 4, so that the protective film 5 protects both the substrate 11 and the optical structure layer 4. It should be noted that the optical structure layer 4 and the protective film 5 may not be provided on the substrate 11.

[0075] See Figure 15 , multiple channels 114 are spaced apart along the width direction of the substrate 11, and each channel 114 extends along the length direction of the substrate 11. The multiple channels 114 formed by the partition 113 separating the first side plate 111 and the second side plate 112 can be distributed in a single layer, that is, the substrate 11 is provided with only one layer of channels 114 in the thickness direction, forming a single-layer channel structure. In this embodiment, the multiple light bars 12 are respectively installed in the multiple channels 114. Specifically, the multiple light bars 12 can be installed in the multiple channels 114 one by one, such as Figure 15 As shown, a light bar 12 can be provided in each channel 114 to improve the brightness and uniformity of the light emitted by the camera panel light. Alternatively, one or more channels 114 can be provided between two adjacent light bars 12 to reduce the arrangement density of the light bars 12 and lower the cost of the camera panel light.

[0076] See Figure 17 In one embodiment, the plurality of channels 114 formed by the partition 113 separating the first side plate 111 and the second side plate 112 may also be distributed in multiple layers, that is, the substrate 11 is provided with multiple layers of channels 114 in the thickness direction to form a multi-layer channel structure, such as Figure 17 As shown. In this embodiment, when the thickness of the substrate 11 is the same and the wall thickness of the first side plate 111 and the second side plate 112 are the same, the multi-layer channel structure is compared with the single-layer channel structure. The multi-layer channel structure can reduce the cross-sectional area of ​​the channel 114, improve the stress resistance of the substrate 11, and prevent the substrate 11 from bending. When the channel structure of each layer is the same, the multi-layer channel structure increases the number of channels 114 in the substrate 11 compared to the single-layer channel structure, thereby increasing the thickness of the substrate 11, improving the stress resistance of the substrate 11, and preventing the substrate 11 from bending.

[0077] In an embodiment in which the substrate 11 has a multi-layer channel structure, the channels 114 on the substrate 11 form multiple channel groups, each channel group includes multiple channels 114, and the multiple channel groups are stacked in the thickness direction of the substrate 11. The stacking arrangement can be a rectangular array distribution or a honeycomb distribution.

[0078] In an embodiment where the substrate 11 is a multi-layer channel structure, the light bar 12 is installed in a channel group close to the outer surface of the substrate 11 to reduce the wall thickness of the substrate 11 that the light emitted by the light bar 12 needs to pass through, thereby improving the light output effect of the photographic camera board light, and preventing the light emitted by the light bar 12 installed in the channel group in the middle position from being blocked by the light bar 12 installed in the channel 114 close to the light-transmitting surface. Among them, a light bar 12 can be provided in each channel 114 of the channel group close to the outer surface of the substrate 11 to improve the brightness and uniformity of the light output of the photographic camera board light. Alternatively, one or more channels 114 can be provided between two adjacent light bars 12 in the channel 114 of the channel group close to the outer surface of the substrate 11 to reduce the arrangement density of the light bars 12 and reduce the cost of the photographic camera board light.

[0079] In the above embodiment, the channel 114 without the light bar 12 can be used to pass the conductive wire 8 so that the conductive wire 8 is concentrated at one end edge of the substrate 11, which facilitates the wiring of the conductive wire 8 between the controller 7 and the light bar 12.

[0080] The light bar 12 is in an elongated shape, and the cross-sectional area of ​​the light bar 12 is smaller than the cross-sectional area of ​​the channel 114 , so that the light bar 12 can be inserted into the channel 114 from one end thereof.

[0081] See Figure 18 The light bar 12 includes a light board 121 and lamp beads 122. The light board 121 is in the shape of an elongated strip. A plurality of lamp beads 122 are provided. The plurality of lamp beads 122 are spaced apart along the length of the light board 121 and arranged on one side of the light board 121. The light-emitting surfaces of the lamp beads 122 face the light-transmitting surface of the substrate 11. A circuit structure is provided on the light board 121. The lamp beads 122 are electrically connected to a power source through the circuit structure, so that the power source can provide electrical energy for the operation of the lamp beads 122.

[0082] The length of the light panel 121 coincides with the direction in which the channel 114 of the base plate 11 extends, and the multiple light bars 12 are arranged sequentially along a direction intersecting the length of the light panel 121. Specifically, the direction in which the multiple light bars 12 are arranged is perpendicular to the length of the light panel 121, that is, the multiple light bars 12 are arranged sequentially along the width of the base plate 11. In other embodiments, the direction in which the multiple light bars 12 are arranged sequentially may form other angles with the length of the light panel 121, such as 60 degrees or 75 degrees.

[0083] An adhesive layer is provided on the side of the light panel 121 facing away from the lamp beads 122 (i.e., the side of the light strip 12 facing away from its light-emitting surface). The light strip 12 is bonded to the base plate 11 via this adhesive layer, making the connection between the light strip 12 and the base plate 11 more convenient. This arrangement simplifies the connection and reduces production costs compared to fabric lighting methods where the LED light panel 121 or light strip 12 is secured to the fabric base plate 11 through sewing or other processes. In other embodiments, the light panel 121 can also be connected to the base plate 11 through riveting or snap-fitting.

[0084] The light board 121 is preferably a PCB board. The PCB board is a rigid structure, which facilitates the insertion of the light bar 12 into the channel 114 through the opening at one end of the channel 114. In other embodiments, the light board 121 may also be an FPC board. An FPC board is a flexible printed circuit board with a smaller thickness. Therefore, an FPC board is lighter than a PCB board, which can further reduce the weight of the camera panel light.

[0085] Lamp beads 122 are preferably LED lamp beads. Compared with traditional incandescent lamps and energy-saving lamps, LED lamp beads have lower energy consumption and more stable light emission. The LED lamp beads can be cool white LED lamp beads, warm white LED lamp beads, or RGB lamp beads. Alternatively, the LED lamp beads can be any combination of cool white LED lamp beads, warm white LED lamp beads, and RGB lamp beads.

[0086] See Figure 19 and Figure 20 In an alternative embodiment, the light bar 12 is disposed on the outer surface of the base plate 11, and the light board 121 is fixed to the outer surface of the base plate 11. The lamp beads 122 are disposed on the side of the light board 121 facing away from the base plate 11. In this embodiment, the base plate 11 can be a hollow plate structure as described above, which reduces the weight of the base plate 11 while ensuring the required hardness of the base plate 11, and also facilitates material procurement and reduces costs. The base plate 11 can also be a solid plate structure. While ensuring the required hardness of the base plate 11, the base plate 11 can be configured as a thin plate to reduce the overall weight of the photography and videography panel light.

[0087] In an embodiment where the light strip 12 is arranged on the outer surface of the substrate 11, the area of ​​the light board 121 of the light strip 12 can be adapted to the outer surface area of ​​the substrate 11, and a plurality of lamp beads 122 are evenly distributed on the light board 121, so that the light strip 12 is an integral structure, making it more convenient to install the light strip 12 on the substrate 11.

[0088] In an embodiment where the substrate 11 is a hollow plate structure and the light bar 12 is disposed on the outer surface of the substrate 11, the conductive wires 8 pass through the channels 114 on the substrate 11 and are concentrated at one edge of the substrate 11, facilitating the routing of the conductive wires 8 between the controller 7 and the light bar 12. In other embodiments, the conductive wires 8 may also be routed along the edge of the substrate 11 or on the side facing away from the light-emitting surface of the light bar 12.

[0089] In an embodiment where the substrate 11 is a solid plate structure and the light bar 12 is disposed on the outer surface of the substrate 11 , the conductive wire 8 may also be arranged on the edge of the substrate 11 or on the side away from the light emitting surface of the light bar 12 .

[0090] The photographic video panel light of the present application includes a plurality of lamp bodies 1 and connectors 2. Each lamp body 1 includes a substrate 11, a light bar 12 arranged on the substrate 11, and a bracket 13 arranged at the edge of the substrate 11. The two ends of the connector 2 are respectively rotatably connected to the brackets 13 on the two adjacent lamp bodies 1, so that the two adjacent lamp bodies 1 can be relatively rotated to the unfolded state, thereby making the photographic video panel light have a larger light output area. The two adjacent lamp bodies 1 can also be relatively rotated to the folded state, so that the photographic video panel light has a smaller storage volume. Therefore, the photographic video panel light occupies a small area when stored and is convenient for users to carry and transport. In addition, the two adjacent lamp bodies 1 are rotatably connected to the connector 2 through the bracket 13, realizing relative rotation between the two adjacent lamp bodies 1, making the connection structure simple.

Since the present invention can be embodied in a variety of forms without departing from the spirit or essence of the invention, it should be understood that the above-described embodiments are not limited to any of the foregoing details, but should be interpreted broadly within the spirit and scope of the appended claims. Therefore, all changes and modifications that fall within the scope of the claims or their equivalents are intended to be covered by the appended claims.
