Description

Technical Field

[0001] This utility model belongs to the field of lighting equipment technology, specifically relating to a supplementary light and a camera device having the same. Background Technology

[0002] With the rapid development of technology, especially in the field of photography and video equipment, lighting equipment plays an increasingly prominent role in shooting quality. As an important auxiliary device, fill lights are widely used in various photography, videography, live streaming and other scenarios.

[0003] When used for extended periods, fill lights can generate excessive heat. If the heat dissipation design is inadequate, the lights may overheat, affecting their stability and lifespan. Traditional fill light equipment typically suffers from issues such as large size, uneven heat dissipation, and complex structure, leading to drawbacks such as unstable light output, susceptibility to damage, and inconvenience in operation. The heat dissipation problem is particularly prominent in scenarios involving continuous shooting or long-term live streaming, which may cause the lights to overheat, flicker, or go out, severely impacting shooting results and user experience.

[0004] Moreover, some existing supplementary lighting devices have an overly bulky design that requires a lot of space, which not only makes it inconvenient to carry and operate the equipment, but also increases production costs and manufacturing difficulty. At the same time, these devices often lack a reasonable internal layout and efficient heat dissipation solutions, which can easily affect the overall stability and service life. Utility Model Content

[0005] To overcome the shortcomings of the prior art, this utility model proposes a supplementary lighting lamp, which includes:

[0006] A supplementary lighting device is used to provide an auxiliary light source;

[0007] A heat dissipation device is provided for dissipating heat from the supplementary lighting device. The heat dissipation device is connected to the supplementary lighting device on the side facing away from the light-emitting surface of the supplementary lighting device.

[0008] The driving device is connected to the supplementary lighting device via a first side drive;

[0009] A power conversion device is disposed on the side of the supplementary lighting device and connected to the driving device on the second side of the driving device; the first side and the second side of the driving device are opposite to each other.

[0010] Specifically, the heat dissipation device includes a first ventilation grid disposed on the side facing away from the light-emitting surface and a first cooling fan disposed between the supplementary lighting device and the first ventilation grid, with the first cooling fan positioned directly opposite the supplementary lighting device.

[0011] Furthermore, the heat dissipation device also includes a plurality of first heat dissipation components disposed on at least one side between the supplementary lighting device and the ventilation grid, wherein the gap between each group of adjacent first heat dissipation components forms an air duct for air outlet on at least one side adjacent to the light-emitting surface.

[0012] Preferably, the driving device is detachably connected to the power conversion device, and the driving device includes a first adjusting member for fixing or disconnecting the connection between the driving device and the power conversion device, the first adjusting member being disposed on the same side of the driving device as the light-emitting surface;

[0013] The driving device further includes a second adjusting member for driving and adjusting the supplementary lighting device, the second adjusting member being disposed on the side of the driving device facing away from the light-emitting surface.

[0014] Preferably, the projected width of the power conversion device on the same side as the light-emitting surface of the supplementary lighting device is smaller than the projected width of the side of the power conversion device connected to the driving device.

[0015] Furthermore, the outer surface of the power conversion device on the same side as the light-emitting surface protrudes from the main structure of the supplementary light, and the overall shape of the supplementary light on the side of the light-emitting surface is a stepped structure or a sloping structure.

[0016] Specifically, the driving device further includes a control circuit, the power conversion device includes a power conversion circuit, and the connection points between the driving device and the power conversion device are provided with contacts for realizing the electrical connection between the control circuit and the power conversion circuit.

[0017] Furthermore, the power conversion device has a power supply port, which is located on the same side as the light-emitting surface or on the side opposite to the light-emitting surface.

[0018] Preferably, the power conversion device includes a second ventilation grid disposed on the side opposite to the drive device and a second cooling fan disposed between the drive device and the second ventilation grid, and a plurality of second heat sinks disposed on at least one side between the drive device and the ventilation grid, wherein the gap between each group of adjacent second heat sinks forms an air duct for air outlet on the side of the second cooling fan.

[0019] This utility model also proposes a photographic device, which includes the fill light.

[0020] This utility model has at least the following beneficial effects:

[0021] The supplementary light proposed in this utility model can effectively avoid the heat of the heat dissipation device directly affecting the light source, ensuring the stability and long-term operation of the supplementary light device, reducing brightness decay or failure caused by overheating, and the power conversion device can realize efficient conversion and transmission of electrical energy, ensuring that the drive device obtains a stable power supply. The overall structure is compact and convenient for users to adjust the position of the supplementary light.

[0022] Furthermore, the heat dissipation device in the supplementary light proposed in this utility model provides a more efficient airflow path through the design of the heat dissipation components, including ventilation mesh, cooling fan, and heat dissipation parts, which optimizes the heat dissipation performance. This allows the hot air at the back of the supplementary light device to be quickly discharged, preventing heat accumulation and thus maintaining the temperature stability of the supplementary light. The detachable connection between the drive device and the power conversion device provides greater flexibility and adjustability. At the same time, the drive device integrates a control circuit and sets contacts, which improves the stability of the electrical connection between the drive device and the power conversion device.

[0023] The side-mounted power conversion device also helps optimize the spatial layout of the fill light, allowing the fill light to maintain a thinner main structure. The different lengths and special shape design of the power conversion device on different sides allow the fill light to make better use of space, avoid conflicts between the power conversion device and the heat dissipation part in the fill light, shorten the heat dissipation channel, improve the convective heat dissipation efficiency between the fill light and the outside world, and make the overall structure of the fill light more concise. When using the fill light by hand, the user can use the power conversion device as a grip to operate the fill light, improving the convenience of use.

[0024] In addition, the power conversion device is also equipped with corresponding heat dissipation components to dissipate heat. The positions of the first adjustment component, the second adjustment component, and the power supply port will not interfere with the light-emitting surface of the supplementary light device. This allows users to hold the supplementary light as a grip, and also makes it easy for users to adjust the supplementary light device and / or the heat dissipation device through the second adjustment component without affecting the use effect of the supplementary light device. It also helps to maintain the ventilation effect of each heat dissipation component and avoids the situation where the user's hands or other body parts may block the heat dissipation during operation. At the same time, the overall structure of the supplementary light is relatively flat, which makes it easy for users to hold and place it.

[0025] Therefore, this utility model provides a fill light and a camera device having the same. The fill light proposed by this utility model can dissipate heat for the fill light device through a heat dissipation device, ensuring that the fill light can provide a stable and continuous light source. The various components of the fill light have reasonable relative positions, making the overall structure of the fill light more compact, reducing the space occupied by the fill light, facilitating user operation, and helping to improve the overall stability of the equipment, while reducing production costs and complexity.

[0042] Example 1

[0043] Please see Figures 1-5 This embodiment proposes a supplementary light, which specifically includes a supplementary light device 1, a heat dissipation device 2, a driving device 3, and a power conversion device 4. The hardware is relatively centralized and the structure is compact, which reduces the space occupied by the supplementary light and lowers the production and usage costs.

[0044] Among them, the supplementary light device 1 is used to provide an auxiliary light source and realize the supplementary light function, and the heat dissipation device 2 is connected to the supplementary light device 1 on the side facing away from the light-emitting surface of the supplementary light device 1, and is used to dissipate heat from the supplementary light device 1.

[0045] The first side and the second side of the driving device 3 are opposite to each other. The driving device 3 drives the supplementary light device 1 through the first side and can drive and adjust the supplementary light device 1 and / or the heat dissipation device 2. The power conversion device 4 is located on the side of the supplementary light device 1 and is connected to the driving device 3 on the second side of the driving device 3. The power conversion device 4 can convert the input voltage into a lower voltage required by the supplementary light.

[0046] In an optional embodiment, the power conversion device 4 includes a power adapter that can convert 220V AC power into 5V DC power for use with the fill light.

[0047] In this embodiment, the supplementary lighting device 1 achieves the supplementary lighting function through the light-emitting surface 11. The light-emitting direction of the light-emitting surface 11 is opposite to the direction of the heat dissipation device 2 relative to the supplementary lighting device 1. The heat dissipation device 2 includes a first ventilation grid 21 disposed on the side facing away from the light-emitting surface 11, and a first cooling fan 22 disposed between the supplementary lighting device 1 and the first ventilation grid 21. The first cooling fan 22 is disposed directly opposite the supplementary lighting device 1.

[0048] The heat dissipation device 2 also includes a plurality of first heat dissipation elements 23 disposed on at least one side between the supplementary lighting device 1 and the first ventilation grid 21, and the gap between each group of adjacent first heat dissipation elements 23 forms an air duct for air outlet on at least one side adjacent to the light-emitting surface 11.

[0049] Preferably, the driving device 3 and the power conversion device 4 are detachably connected. The driving device 3 includes a first adjusting member 31 for fixing or releasing the connection between the driving device 3 and the power conversion device 4. In this embodiment, the first adjusting member 31 includes a button, which is located on the same side of the driving device 3 as the light-emitting surface 11. The driving device 3 and the power conversion device 4 can be connected through a quick-connect structure. The user can connect the driving device 3 and the power conversion device 4 by inserting the power conversion device 4 into the connection slot 34 provided in the driving device 3, or release the connection between the driving device 3 and the power conversion device 4 by pressing the button when the driving device 3 and the power conversion device 4 are in the connected state, thereby allowing the user to release the connection between the driving device 3 and the power conversion device 4.

[0050] The driving device 3 also includes a second adjusting member 32 for driving and controlling the supplementary lighting device 1 and the heat dissipation device 2. In this embodiment, the second adjusting member 32 includes an adjusting button and an adjusting knob. The adjusting button and the adjusting knob are both located on the side of the driving device 3 facing away from the light-emitting surface 11. The user can adjust the output power of the supplementary lighting device 1 by pressing the adjusting button and / or rotating the adjusting knob to adjust the supplementary lighting intensity or light emission effect of the supplementary lighting device 1. Alternatively, the user can adjust the rotation speed of the cooling fan in the heat dissipation device 2 by pressing the adjusting button and / or rotating the adjusting knob to adjust the heat dissipation intensity of the heat dissipation device 2.

[0051] Specifically, the drive device 3 also includes a control circuit, and the power conversion device 4 includes a power conversion circuit. The connection between the drive device 3 and the power conversion device 4 is provided with contacts for realizing the electrical connection between the control circuit and the power conversion circuit. The setting of contacts in the control circuit and the drive device 3, and contacts in the power conversion device 4 can ensure that the electrical connection between the drive device 3 and the power conversion device 4 is stable and reliable.

[0052] Please see Figure 5 In this embodiment, the connection point of the drive device 3 is provided with a connection point 33. When the power conversion device 4 is connected to the drive device 3, the connection point 33 in the drive device 3 and the contact in the power conversion device 4 can be accurately electrically connected, so that the power conversion device 4 can accurately convert the input high voltage into a low voltage suitable for the fill light, and ensure that the current and signal transmission are not interfered with, thereby ensuring the normal operation of the fill light.

[0053] Moreover, the contact design enables fast and efficient electrical connection when the drive unit 3 and the power conversion unit 4 are disassembled and connected. Users can achieve electrical connection between the drive unit 3 and the power conversion unit 4 through simple connection and disconnection actions, reducing failures or damage caused by unstable electrical connection, ensuring long-term stable operation of the equipment, and simplifying the process of using and maintaining the supplementary lighting.

[0054] Furthermore, the power conversion device 4 is also provided with a power supply port 41. The power supply port 41 in the power conversion device 4 is the connection point between the power conversion device 4 and the external power source, and plays the role of direct connection with the external power source. By receiving electrical energy from the external power source through the power supply port 41, the power conversion device 4 can convert and provide the electrical energy required by the fill light, which helps to simplify the use, disassembly and maintenance of the fill light. During the use of the fill light, the user only needs to connect the power supply port 41 through the external power source to make the power conversion device 4 work normally.

[0055] Preferably, the power supply port 41 is located on the side adjacent to the light-emitting surface 11 or on the side away from the light-emitting surface 11. Specifically, when the side where the light-emitting surface 11 is located is considered as the front, the power supply port 41 can be located on any side of the back, top, bottom or left side of the supplementary light. As long as it is not on the same side as the light-emitting surface 11, the power supply cable connected to the power supply port 41 can be effectively prevented from interfering with the light-emitting effect of the light-emitting surface 11. This design not only ensures that the supplementary light effect of the supplementary light device 1 is not affected, but also makes the arrangement of the power cable more reasonable, and will not affect the normal use of the supplementary light due to the tangling or improper placement of the power cable.

[0056] Therefore, the positions of the first adjustment component 31, the second adjustment component 32, and the power supply port 41 will not interfere with the lighting effect of the light-emitting surface 11 in the supplementary lighting device 1. This allows users to easily adjust the brightness or cooling fan speed through the second adjustment component 32 without affecting the use effect of the supplementary lighting device 1. Furthermore, the positions of the first adjustment component 31, the second adjustment component 32, and the power supply port 41 also help maintain the ventilation and heat dissipation effect of each heat dissipation component in the heat dissipation device 2 and the power conversion device 4, avoiding the situation where the user's hands or other body parts may block the heat dissipation during operation, thus making it more convenient for the user to operate.

[0057] In addition, the positions of the first adjusting member 31, the second adjusting member 32 and the power supply port 41 can make the overall structure of the fill light proposed in this embodiment relatively flat, making it convenient for users to hold the fill light and place it stably.

[0058] It should be noted that the function of the power conversion device 4 is to convert and provide the electrical energy required by the fill light. Since the connection between the drive device 3 and the power conversion device 4 in the fill light proposed in this embodiment is detachable, when using the fill light proposed in this embodiment, the user can directly connect the drive device 3 to an external power supply adapted to the fill light instead of connecting it to the power conversion device 4, so that the external power supply directly supplies power to the fill light. When there is no external power supply adapted to the fill light, the drive device 3 can be connected to the power conversion device 4, and then the power conversion device 4 can convert the electrical energy provided by the external power supply connected to the power conversion device 4, which cannot be directly applied to the operation of the fill light, into suitable electrical energy that can be used for the operation of the fill light.

[0059] Preferably, the projection width of the power conversion device 4 on the same side as the light-emitting surface 11 of the supplementary lighting device 1 is smaller than the projection width of the power conversion device 4 on the side connected to the driving device 3.

[0060] Furthermore, the outer surface of the power conversion device 4 on the same side as the light-emitting surface 11 can also be configured as a main structure protruding from the supplementary light, and the overall shape of the supplementary light on the side of the light-emitting surface 11 proposed in this embodiment can be a stepped structure or a sloping structure.

[0061] Therefore, users can use the power conversion device 4 as a grip to use the fill light proposed in this embodiment, and when users hold the fill light through the power conversion device 4, their fingers can easily access and use the second adjustment member 32.

[0062] Preferably, the power conversion device 4 includes a second ventilation grid 42 disposed on the side opposite to the drive device 3 and a second cooling fan 43 disposed between the drive device 3 and the second ventilation grid 42.

[0063] Furthermore, the power conversion device 4 also includes a plurality of second heat sinks 44 disposed on at least one side between the drive device 3 and the second ventilation grid 42. The gap between each group of adjacent second heat sinks 44 forms an air duct on the side of the second cooling fan 43. The second cooling fan 43 and the second heat sinks 44 can cooperate with each other to dissipate heat for the drive device 3 and the power conversion device 4.

[0064] It should be noted that the first heat sink 23 and the second heat sink 44 provided in this embodiment can effectively improve the overall airflow of the heat dissipation device 2, and can work with the cooling fan to achieve the purpose of dissipating heat from the supplementary lighting device 1, the driving device 3, and the power conversion device 4. The first heat sink 23 and the second heat sink 44 can be set as straight or curved columnar structures or sheet structures. Figures 1-2 The first heat sink 23 and the second heat sink 44 are shown to be straight sheet-like structures.

[0065] Preferably, the spacing between adjacent first heat sinks 23 is the same, and the spacing between adjacent second heat sinks 44 is the same, so that the gap width between adjacent first heat sinks 23 is the same and the gap width between adjacent second heat sinks 44 is the same. With this arrangement, the first heat sinks 23 and the second heat sinks 44 can have a uniform heat dissipation effect.

[0066] Example 2

[0067] This embodiment proposes a camera device, which includes a supplementary light as described in Embodiment 1. The addition of the supplementary light effectively improves the shooting effect of the camera device in low-light environments, making the captured images clearer, brighter, with richer details and more accurate color reproduction. This is of great significance for improving the shooting quality in fields such as film and television production, live video streaming, security monitoring, and news interviews. With the supplementary light, the camera device can be used in a wider range of lighting conditions, without being limited by ambient light. Whether indoors or outdoors, day or night, it can achieve ideal shooting effects, thereby greatly enhancing the applicability and versatility of the camera device. The supplementary light provides users with a more stable shooting experience. When using a camera device equipped with a supplementary light, users can perform shooting operations more conveniently without having to carry additional supplementary lighting equipment, reducing the burden on users and helping to improve user satisfaction with the camera device.

[0068] Optionally, the main body of the camera device in this embodiment can be a common handheld camera, a fixed surveillance camera, or a professional film and television shooting camera, etc. The main body of the camera device has basic shooting functions, can capture image and video information, and store them in a built-in or external storage medium.

[0069] In one optional implementation, the fill light can be integrated into the main body of the camera device in a fixed manner; the fixed integration method can ensure that the fill light and the camera device maintain a relatively stable positional relationship during use, avoiding the fill light from becoming loose or shifting due to external forces or other factors, thereby ensuring the stability and reliability of the fill light effect;

[0070] In another alternative implementation, the fill light can also be detachably integrated with the main body of the camera device. For example, please refer to... Figure 5 The camera equipment can be equipped with a dedicated mounting interface or slot, and the fill light can be firmly installed in a specific position on the main body of the camera equipment, such as above the lens, the side or the back, through the bracket 5. The detachable integration method makes it easy for users to flexibly install or remove the fill light according to different shooting needs and scenes.

[0071] For example, when shooting in well-lit environments, users can detach the fill light to reduce the weight and size of the camera equipment, making it easier to carry and operate; while in low-light environments, the fill light can be installed to obtain better shooting results. Detachable integration can be achieved through magnetic, snap-fit, or threaded connections, making it convenient for users to quickly install and remove the fill light.

[0072] Based on this, the fill light and the camera body in the camera equipment can share a power system or be powered independently. The brightness adjustment and on / off control of the fill light can also be operated through the control panel of the camera equipment or a remote control device, so that users can adjust the brightness and color temperature of the fill light according to the shooting mode of the camera equipment to adapt to different shooting needs.

[0073] In summary, this utility model provides a fill light and a camera device incorporating it. The fill light proposed by this utility model can dissipate heat from the fill light device through a heat dissipation device, ensuring that the fill light can provide a stable and continuous light source. The various components of the fill light have reasonable relative positions, making the overall structure of the fill light more compact, reducing the space occupied by the fill light, facilitating user operation, and helping to improve the overall stability of the equipment, while reducing production costs and complexity.

[0074] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
