[0027] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments.

[0029] For ease of description, spatial relative terms may be used herein to describe the relative position or movement of one element or feature relative to another element or feature as shown in the figure, such as "center", "longitudinal", "lateral", "length", "width", "thickness", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside". Such spatial relative terms are intended to include different orientations of the device in use or operation other than the orientation depicted in the figure.

Therefore, the example term "below..." can include both the above and below orientations. The device can be oriented otherwise (rotated 90 degrees or in other directions) and the spatial relative descriptors used herein are interpreted accordingly.

[0030] In the description of the present application, “plurality” means two or more.

[0031] In order to solve the technical problems in the prior art that the photography lights occupy a large space and cannot synchronously dissipate heat for multiple light-emitting elements, the present application provides a photography light 100, which includes multiple light-emitting elements 10, a heat dissipation pipe 20 and a heat dissipation element 30.

[0032] Specifically, if Figure 1 and Figure 2 As shown, there are multiple heat dissipation pipes 20 corresponding to the light emitting elements 10, the heat dissipation pipes 20 are suitable for the flow of coolant, the first end of each heat dissipation pipe 20 is connected to the corresponding light emitting element 10, the heat dissipation element 30 is used to dissipate the coolant in the multiple heat dissipation pipes 20, and the second ends of the multiple heat dissipation pipes 20 are all connected to the heat dissipation element 30. For example, the light emitting element 10 can be a COB (Chip On Board Light, high-power integrated surface light source) light source.

[0033] Thus, the heat dissipation element 30 can dissipate heat for multiple light-emitting elements 10 through the coolant in the heat dissipation pipe 20 to prevent the situation where heat of the multiple light-emitting elements 10 is accumulated and cannot be dissipated. In addition, such an arrangement can realize that a single heat dissipation element 30 dissipates heat for multiple light-emitting elements 10, which can reduce the occupied space. Moreover, multiple heat dissipation channels 20 are arranged in parallel, and multiple light-emitting elements 10 can be dissipated synchronously according to actual needs to ensure the heat dissipation effect of each light-emitting element 10, or multiple light-emitting elements 10 can be independently dissipated through multiple heat dissipation channels 20 according to actual needs, so that the cooling temperature of the light-emitting element 10 is not affected by the cooling temperature of other light-emitting elements 10.

[0034] In some embodiments, Figure 2 As shown, the heat dissipation pipe 20 includes a first pipe 21 and a second pipe 22. The coolant in the first pipe 21 is suitable for flowing from the heat dissipation element 30 toward the light-emitting element 10, and the coolant in the second pipe 22 is suitable for flowing from the light-emitting element 10 toward the heat dissipation element 30; the light-emitting element 10 has a first coolant receiving chamber (not shown in the figure), and the heat dissipation element 30 has a second coolant receiving chamber (not shown in the figure). The first end of the first pipe 21 is connected to the first end of the second pipe 22 through the first coolant receiving chamber, and the second end of the first pipe 21 is connected to the second end of the second pipe 22 through the second coolant receiving chamber.

[0035] For example, there may be multiple second cooling liquid containing chambers corresponding to the heat dissipation pipes 20, and the multiple heat dissipation pipes 20 are respectively connected to the multiple second cooling liquid containing chambers; or there may be one second cooling liquid containing chamber, and each heat dissipation pipe 20 may be connected to the second cooling liquid containing chamber. The above two situations can be flexibly arranged according to actual conditions and are not limited here.

[0036] Therefore, by setting the first pipe 21 and the second pipe 22, a coolant circulation channel can be constructed together with the first coolant receiving chamber and the second coolant receiving chamber. By setting the first coolant receiving chamber located in the light-emitting element 10 and the second coolant receiving chamber located in the heat dissipation element 30, the heat exchange area and heat exchange effect of the coolant can be increased.

[0037] In some embodiments, the first pipe 21 and the second pipe 22 are spaced apart, or a heat insulating layer may be provided between the first pipe 21 and the second pipe 22. Furthermore, the first pipe 21 and the second pipe 22 are spaced apart, and a heat insulating layer may be provided between the first pipe 21 and the second pipe 22. The heat insulating layer may be a material with poor thermal conductivity, such as an asbestos layer or a resin layer. Thus, heat exchange between the coolant flowing from the first pipe 21 to the first coolant receiving chamber and the coolant in the second pipe 22 can be avoided, so as to ensure that the temperature of the coolant flowing to the first coolant receiving chamber is low, so as to ensure the heat dissipation effect and heat exchange efficiency of the light-emitting element 10.

[0038] In some embodiments, Figure 2 As shown, the photography light 100 may further include: electrical connection wires 40, which are multiple and arranged corresponding to the light emitting elements 10, and each electrical connection wire 40 is electrically connected to the light emitting element 10 and the heat dissipation element 30 corresponding thereto. In other words, the heat dissipation element 30 may be a controller, and the heat dissipation control and the light emission control of the light emitting element 10 may be integrated together to further reduce the occupied space.

[0039] In some embodiments, Figure 1 and Figure 2 As shown, the photography light 100 may further include an outer tube 50, which is disposed on the outer periphery of the heat dissipation pipe 20 and the electrical connection line 40. For example, there may be a plurality of outer tubes 50 disposed corresponding to the heat dissipation pipe 20, and the heat dissipation element 30 may have a plurality of interfaces 31 disposed corresponding to the outer tube 50, so that a single heat dissipation element 30 may be assembled with and disassembled from a plurality of outer tubes 50 through the plurality of interfaces 31. By providing the outer tube 50, on the one hand, it can protect the heat dissipation pipe 20 and the electrical connection line 40; on the other hand, it can improve the neatness.

[0040] In some embodiments, at least one of the heat dissipation pipe 20 and the outer pipe 50 is a flexible pipe. For example, the flexible pipe may be a shaped hose. For example, the heat dissipation pipe 20 is a flexible pipe, or the outer pipe 50 is a flexible pipe, and further, the heat dissipation pipe 20 and the outer pipe 50 may both be flexible pipes. Thus, it is convenient to adjust the positions between the plurality of heat dissipation pipes 20 and the plurality of outer pipes 50 for easy installation, and it is helpful to prevent interference between the plurality of heat dissipation pipes 20.

[0041] In some embodiments, an air cooling part (not shown) is provided in the heat dissipation element 30, and the air outlet of the air cooling part is arranged toward the heat dissipation pipe 20, and / or a heat dissipation fin (not shown) is provided in the heat dissipation element 30, and the heat dissipation fin is arranged adjacent to or in contact with the heat dissipation pipe 20, and / or a heat conductive layer (not shown) is provided in the heat dissipation element 30, and the heat conductive layer is attached to the heat dissipation pipe 20. The air cooling part can be a fan, which can dissipate the heat of the coolant by increasing the air flow rate. The heat dissipation fin can increase the heat exchange area with the heat source, so that the heat is transferred to the heat dissipation fin through the pipe wall, and then dissipated to the surrounding environment through the heat dissipation fin, so as to improve the heat dissipation efficiency of the coolant. The heat conductive layer can be a material with high thermal conductivity such as a graphite layer or a metal layer to improve the heat dissipation efficiency. The above three heat dissipation methods can be set separately or simultaneously, so as to improve the heat dissipation efficiency and heat dissipation effect of the coolant.

[0042] In some embodiments, Figure 1 As shown, the heat dissipation element 30 has a shell 32, the second end of the heat dissipation pipe 20 is located in the shell 32, and the shell 32 has at least one heat dissipation hole 321. For example, there can be multiple heat dissipation holes 321, and the two sides of the shell 32 opposite to each other have multiple heat dissipation holes 321, so as to improve the air flow efficiency and facilitate the heat dissipation from the heat dissipation element 30.

[0043] In some embodiments, the plurality of light emitting elements 10 are arranged at intervals. In this way, on the one hand, the heat generated by the plurality of light emitting elements 10 can be further prevented from accumulating; on the other hand, the uniformity of the light emission and the irradiation area of ​​the video light 100 can be improved.

[0044] In some embodiments, the heat dissipation element 30 has a plurality of connection holes (not shown) corresponding to the plurality of heat dissipation pipes 20, and the heat dissipation pipes 20 are inserted into the connection holes, wherein the plurality of connection holes may be interconnected or may be arranged at intervals. Thus, the second end of the heat dissipation pipe 20 extends into the heat dissipation element 30 through the connection hole to dissipate the coolant in the heat dissipation pipe 20, and the heat dissipation pipe 20 and the light-emitting element 10 may be flexibly arranged according to actual needs. For example, each connection hole may include a first connection sub-hole and a second connection sub-hole arranged at intervals, and the second end of the first pipe 21 may extend into the heat dissipation element 30 through the first connection sub-hole, and the second pipe 22 may extend into the heat dissipation element 30 through the second connection sub-hole.

[0045] In some embodiments, Figure 2 As shown, a plurality of light emitting elements 10 are arranged side by side and at intervals, and the heat dissipation pipes 20 corresponding to the light emitting elements 10 at the edge have a bending section 23. Figure 1As shown, three light emitting elements 10 may be arranged side by side and at intervals, and the heat dissipation pipe 20 corresponding to the light emitting element 10 in the middle may be constructed as a straight line. The heat dissipation pipes 20 corresponding to the light emitting elements 10 on both sides may have a bending section 23, for example, the first pipe and the second pipe 22 may both have a bending section 23, and the extension direction of the outer pipe 50 may be the same as the extension direction of the first pipe 21 and the second pipe 22. By providing the bending section 23, the distance between the first ends of two adjacent heat dissipation pipes 20 can be greater than the distance between their second ends, so as to improve the heat dissipation effect.
