[0052] The present application provides a handheld photography light with enhanced heat dissipation and no wind blocking, such as Figures 1 to 7 As shown, it includes: a photography light body 1, a heat conduction component 2 and a heat dissipation component 3;

[0053] like Figure 1 , Figure 2 and Figure 4 As shown, the photographic light body 1 is connected to the heat-conducting component 2, and the heat-conducting component 2 is connected to the heat-dissipating component 3; the heat generated by the photographic light body is conducted to the heat-dissipating component 3 through the heat-conducting component 2, thereby achieving heat dissipation of the photographic light body 1 and reducing the temperature of the area where the photographic light body 1 is located.

[0054] The photography light body 1 includes: a light board 11 and a main board 12 electrically connected to each other, and the heat conduction component 2 includes: a heat conduction plate 21 and a heat conduction member 22;

[0055] The heat dissipation assembly 3 includes: a heat sink 33, a first fan 31 and a second fan 32 electrically connected to the mainboard 12;

[0056] The lamp board 11 and the main board 12 in the photography light body 1 are the main sources of heat generated by the photography light. The lamp board 11 is arranged on one side of the heat conducting plate 21, and the main board 12 is arranged on the other side of the heat conducting plate 21 away from the lamp board 11, so that the lamp board 11 and the main board 12 are fully fitted with the heat conducting plate 21, respectively, and the surface area of ​​the heat conducting plate 21 is fully utilized, thereby increasing the heat conducting area of ​​the photography light body 1, so that the heat conducting plate 21 can quickly absorb and dissipate the heat released by the lamp board 11 and the main board 12, thereby reducing the surface temperature of the lamp board 11 and the main board 12;

[0057] A heat conducting member 22 is provided, and the heat conducting plate 21 is connected to the radiator 33 through the heat conducting member 22, which optimizes the overall layout structure of the photographic light, and changes the previous layout in which the radiator 33 is arranged at the lower end of the light board 11, the circuit board is arranged at the end of the radiator 33, the heat dissipation duct 4 is easily blocked, and the heat dissipation effect is poor;

[0058] Furthermore, the radiator 33 can be in direct contact with the external environment, reducing the obstacles to heat exchange with the outside air and accelerating the heat dissipation rate.

[0059] The first fan 31 and the second fan 32 are respectively disposed on both sides of the heat sink 33 to form a heat dissipation duct 4 from the first fan 31 to the second fan 32;

[0060] Specifically, in some embodiments of the present application, the blowing directions of the first fan 31 and the second fan 32 are oppositely arranged, the first fan 31 blows from the outside to the radiator 33, and the second fan 32 blows from the radiator 33 to the outside; the first fan 31 is used to blow outside air into the radiator 33, and the second fan 32 is used to draw the air in the radiator 33 out of the radiator 33, the heat dissipation duct 4 runs through the radiator 33, and there is no obstruction or the obstruction is small between the heat dissipation ducts 4, the gas flows more smoothly, so as to form convection in the area where the radiator 33 is located, accelerate the flow of airflow, accelerate the process of gas heat exchange, and further optimize the heat dissipation effect.

[0061] Furthermore, if Figure 6 and Figure 7 As shown, the heat sink 33 includes at least two heat dissipation fins 301;

[0062] All the heat dissipation fins 301 are arranged at equal distances, and heat dissipation gaps 302 are formed between adjacent heat dissipation fins 301 . The heat dissipation gaps 302 are connected to the heat dissipation air duct 4 .

[0063] The equidistant design of the heat dissipation fins 301 can effectively increase the surface area of ​​the heat sink 33, provide more heat dissipation surfaces, and thus increase the heat dissipation efficiency;

[0064] The connection between the heat dissipation gap 302 and the heat dissipation air duct 4 can promote the flow of air, so that the heat inside the radiator 33 is more easily taken away by the airflow, thereby enhancing the heat dissipation effect;

[0065] The equidistantly arranged heat dissipation fins 301 can also evenly distribute the heat on the entire surface of the heat sink 33, avoiding the concentration of hot spots and improving the uniformity of heat dissipation;

[0066] Reasonable arrangement of the heat dissipation gaps 302 and the heat dissipation ducts 4 can also reduce noise generated during air flow and provide a silent heat dissipation effect.

[0067] Specifically, in some embodiments of the present application, the extension direction of the heat dissipation gaps 302 formed between adjacent heat dissipation fins 301 is arranged parallel to the direction of the heat dissipation duct 4;

[0068] The above design, on the one hand, helps to reduce the obstruction of the heat dissipation fins 301 when the gas flows in the heat dissipation duct 4, reduces the friction, and enables the gas to pass through the radiator 33 more smoothly, thereby improving the heat dissipation speed;

[0069] On the other hand, when the gas passes through the radiator 33, it can fully contact the outer surface of the heat dissipation fins 301, thereby improving the heat dissipation efficiency and optimizing the heat dissipation effect;

[0070] On the other hand, it is also beneficial to maintain the consistency of gas flow direction when the air in the heat dissipation duct 4 flows through the radiator 33, optimize the heat dissipation performance; simplify the structural design, and reduce the manufacturing cost.

[0071] Furthermore, the shape of the heat dissipation fin 301 includes a wave shape, a straight wing shape, a layered shape, or a sawtooth shape.

[0072] Optionally, in some embodiments of the present application, the shape of the heat dissipation fins 301 may be wavy, which can improve air flow, increase heat dissipation efficiency, and reduce noise generation;

[0073] It can also be a straight wing shape, which can provide a larger surface area and increase heat dissipation efficiency, but may produce greater noise;

[0074] It can also be in the form of layers, with reasonable fin arrangement and spacing settings to optimize air flow, allowing better air circulation and increasing heat transfer and dissipation;

[0075] Or it can be serrated, which can increase the surface area and improve air flow, increase heat dissipation efficiency, and also reduce vibration noise between fins.

[0076] Furthermore, the main board 12 and / or the lamp board 11 are connected to the heat conducting plate 21 via a heat conducting adhesive plate (not shown in the figure).

[0077] The thermally conductive adhesive plate is usually made of a thermally conductive material, which can provide better thermal conductivity and effectively transfer the heat generated by the expansion dock mainboard 12 to the thermally conductive plate 21, which helps to reduce the temperature of the mainboard 12 and the light board 11 and improve the heat dissipation efficiency.

[0078] The thermally conductive adhesive plate can also fill the irregular surfaces between the thermally conductive plate 21 and the main board 12 and the lamp board 11 to fill any tiny gaps and voids that may exist, which helps to reduce thermal resistance and allow heat to be more evenly conducted to the thermally conductive plate 21 .

[0079] The thermally conductive adhesive plate can also play a role in buffering and shock absorption, which can reduce the transmission of mechanical vibration, thereby reducing noise generation and improving the overall user experience.

[0080] The use of a thermally conductive adhesive plate can also simplify the connection process between the thermally conductive plate 21 and the main board 12 and the lamp board 11 , and can provide a reliable connection while facilitating the removal and replacement of the lamp board 11 or the maintenance of the main board 12 .

[0081] Further, the light board 11 includes a first light board 101 and a second light board 102;

[0082] Specifically, in some embodiments of the present application, the first light board 101 is a cob (Chip-on-Board) lamp, and the second light board 102 is a surface lamp;

[0083] The first lamp panel 101 is detachably connected with a reflective lampshade 51 , and the second lamp panel 102 is covered with a soft light cover 52 .

[0084] The first light board 101 is detachably connected with a reflective lampshade 51, which is used to reflect and diffuse light to provide a more uniform lighting effect; the second light board 102 is covered with a soft light cover 52, which makes the light of the second light board 102 softer, reduces glare and shadows, and obtains a softer and more uniform lighting effect;

[0085] The reflective lampshade 51 and the soft light cover 52 are provided to provide different lighting effects and light control effects for the photographic light. The reflective lampshade 51 of the first light board 101 can change the reflection and propagation mode of the light, while the soft light cover 52 on the second light board 102 can change the texture and uniformity of the light.

[0086] The photographic light can then switch between different light modes to meet the needs of different application scenarios.

[0087] Furthermore, a housing 6 is provided, and the housing 6 includes a front cover 61 and a rear cover 62;

[0088] Specifically, in some embodiments of the present application, the housing 6 is an aluminum alloy housing 6, and a heat dissipation coating (not shown in the figure) is also provided on the surface of the housing 6;

[0089] The housing 6 is made of aluminum alloy, which has good thermal conductivity, is convenient for dissipating heat, reduces the surface temperature of the docking station, avoids overheating of the docking station, and protects the normal operation of the docking station;

[0090] Aluminum alloy has a lower density. Using aluminum alloy can reduce the overall weight of the docking station, making it easier to carry and install.

[0091] The heat dissipation coating generally has a high thermal conductivity, which can improve the thermal conductivity of the surface of the aluminum alloy shell 6. Heat can be conducted more quickly from the inside of the video light to the surface of the shell 6 and quickly dissipated to the surrounding environment, thereby improving the heat dissipation efficiency;

[0092] Optionally, the heat dissipation coating may use metal coatings such as copper and aluminum, or ceramic coatings with high thermal conductivity; a heat-resistant polymer coating; or a thermal conductive paste.

[0093] It is understandable that there is no limitation on the specific selection of the heat dissipation coating material.

[0094] One of the front cover 61 and the rear cover 62 is provided with a buckle 601 , and the other of the two is provided with a slot 602 ; the detachable connection between the front cover 61 and the rear cover 62 is achieved by engaging the buckle 601 with the slot 602 .

[0095] Optionally, the buckle 601 can be provided on the front cover 61 or on the rear cover 62; the card slot 602 can be provided on the rear cover 62 or on the front cover 61;

[0096] Specifically, in some embodiments of the present application, the buckle 601 is set on the front cover 61 and the slot 602 is set on the rear cover 62. The detachable connection between the buckle 601 and the slot 602 facilitates the installation and maintenance of the photographic light.

[0097] Of course, there is no limitation on the design of the specific positions of the buckle 601 and the slot 602 .

[0098] Specifically, in some embodiments of the present application, the front cover 61 is a transparent structure, or is provided with a light-guiding structure to guide the light released by the light board 11 to pass through the housing 6 to provide lighting.

[0099] Furthermore, the photography light body 1 and the heat conducting plate 21 are disposed in the housing 6, which helps to provide protection and support for the photography light body 1, prevents the photography light body 1 from being damaged, thereby extending the service life, and reduces the overall volume of the product;

[0100] One end of the heat conducting member 22 is connected to the heat conducting plate 21, and the other end of the heat conducting member 22 extends out of the housing 6 to connect to the heat dissipation assembly 3, which can effectively transfer heat from the main body to the heat conducting plate 21 and the heat sink 33, and further dissipate the heat into the air. The heat dissipation assembly 3 is arranged on the rear cover 62;

[0101] The heat dissipation component 3 is arranged outside the shell 6, which expands the spatial range of heat exchange of the heat dissipation component 3, and the heat exchange speed with the external air is faster and the exchange range is wider, which can further optimize the heat dissipation function of the photographic light.

[0102] Optionally, in terms of material, the heat conducting plate 21 and the heat conducting member 22 may be made of copper metal, aluminum metal, or copper-aluminum alloy;

[0103] Specifically, in some embodiments of the present application, the heat conducting plate 21 is made of aluminum metal, and the heat conducting member 22 is made of copper metal;

[0104] Of course, there is no limitation on the specific materials of the heat conducting plate 21 and the heat conducting member 22 .

[0105] Furthermore, a quick-detachable battery 7 is provided, the battery 7 is electrically connected to the mainboard 12 , and the battery 7 and the heat dissipation assembly 3 are arranged on the housing 6 on the same side.

[0106] The photography light is provided with a quickly detachable battery 7, which is convenient for the user to replace the battery 7 and improves the use efficiency;

[0107] The battery 7 is electrically connected to the main board 12 of the video light, so that the video light can work normally. The battery 7 and the heat dissipation assembly 3 are arranged on the same side of the housing 6. The battery 7 and the heat dissipation assembly 3 are integrated, which is conducive to centralized management and arrangement of the battery 7 and the heat dissipation assembly 3, while reducing the overall size of the video light.

[0108] The battery 7 is arranged on the outer side of the housing 6 so that the battery 7 is sufficiently spaced from the mainboard 12 to avoid affecting the performance of the battery 7 due to the heat generated by the mainboard 12, which helps to extend the service life of the battery 7.

[0109] Furthermore, if Figure 2 As shown, the battery 7 is also provided with a hand-held portion 71, and the shape of the hand-held portion 71 matches the holding shape of a human hand and conforms to ergonomics;

[0110] To make it easier for users to carry and operate the video light, a hand-held portion 71 is usually provided on one side or the top of the battery 7, providing a gripping area so that users can firmly grasp the video light, freely move the video light, adjust the lighting angle, and shoot different scenes.

[0111] The design of the hand-held portion 71 fully considers ergonomics to ensure comfort and stability in holding.

[0112] Furthermore, a mounting groove 221 matching the shape of the heat conducting element 22 is provided on the heat conducting plate 21 , and the heat conducting element 22 is connected to the heat conducting plate 21 by being embedded in the mounting groove 221 .

[0113] The heat conducting member 22 is embedded in the mounting groove 221 to provide a more stable and reliable connection mode. Through the mounting groove 221 with a matching shape, the heat conducting member 22 can be accurately inserted into the heat conducting plate 21, thereby achieving a close connection between the heat conducting member 22 and the heat conducting plate 21 and maintaining a stable position; so that the heat conducting member 22 will not easily slide out of the heat conducting plate 21, thereby avoiding damage to other components inside the video light;

[0114] The heat conductive member 22 is embedded in the mounting groove 221, which can effectively increase the contact surface between the heat conductive member 22 and the heat conductive plate 21, that is, increase the heat conduction area between the heat conductive member 22 and the heat conductive plate 21, which can maximize the heat transfer efficiency and ensure that the heat conductive member 22 can effectively transfer the heat from the heat conductive plate 21 to the radiator 33, so as to facilitate further heat dissipation processing.
