Technical Field

[0001] This utility model relates to the field of close-up photography technology, and in particular to close-up photography fill light and lighting system. Background Technology

[0002] In photography and videography, close-up shooting techniques are often used when photographing flowers, insects, or small objects. When shooting at close range, it is necessary to set up a supplementary light source near the subject in order to capture a clear image.

[0003] A new type of close-up shooting fill light has appeared on the market. Its main body is connected to an LED light source through two flexible tubes to provide fill light for photography and videography.

[0004] However, since the LED light sources in existing close-up shooting fill lights all use natural heat dissipation, they can only meet the heat dissipation requirements of low-power operation of LED light sources, resulting in low brightness of close-up shooting fill lights, which cannot well meet the current lighting requirements for close-up shooting.

Each lamp head assembly includes a lamp holder, a connecting hose, an LED light source, and an electrical connection wire. The lamp holder is connected to the main body base via the connecting hose, such that the connecting hose can support the lamp holder, and the connecting hose is deformable and capable of... The lamp holder is shaped to adjust its position relative to the main body. A connecting flexible tube has a communicating channel, and the electrical connecting wire is housed within this channel. The LED light source is electrically connected to the main control component via the connecting wire. The lamp holder has an open mounting cavity on one side, and the LED light source is installed within this cavity, corresponding to the open opening, so that the light emitted by the LED light source can illuminate the outside of the lamp holder. The mounting cavity connects to the housing cavity via the communicating channel to form a heat dissipation channel. An air inlet and an air outlet are connected within this heat dissipation channel, allowing the cooling fan to drive airflow within the channel and dissipate heat from the LED light source.

[0007] In one embodiment of this application, the air inlet is provided on the side wall of the lamp holder so that the air inlet communicates with the mounting cavity, and the air outlet is provided on the side wall of the main body so that the air outlet communicates with the receiving cavity.

[0008] In one embodiment of this application, the number of cooling fans is the same as the number of lamp head assemblies, and each cooling fan corresponds to each connecting hose.

[0009] In one embodiment of this application, the lamp holder is provided with a connecting part located on the outer periphery of the lamp holder, and the connecting part includes a connecting slot for detachably connecting photographic accessories.

[0010] In one embodiment of this application, two connecting portions are provided, and the two connecting portions are provided on opposite side walls of the lamp holder.

[0011] In one embodiment of this application, the connecting portion includes an electrical contact, which is electrically connected to the electrical connection line, and the electrical contact is used to electrically connect a flash lamp.

[0012] In one embodiment of this application, the close-up shooting fill light further includes a display component and a battery.

The display component is connected to the outer peripheral side of the main body and is electrically connected to the main control component.

[0013] In one embodiment of this application, the central axis of the mounting part is set at an angle to the central axis of the main body base, and the mounting part is provided with an electrical connector that is electrically connected to the main control component, so that when the mounting part is connected to the shooting device, the shooting device can be electrically connected to the main control component through the electrical connector.

[0014] In one embodiment of this application, the main control component is provided with a flash control module, which is used to drive the LED light source to emit a flash.

[0015] In one embodiment of this application, the close-up shooting fill light further includes a control component, which is mounted on the side wall of the main body and located on the same side as the display component. The control unit is electrically connected to the main control component.

[0016] This application also provides a lighting system including a photographic accessory and any of the close-up shooting fill lights described above, wherein the photographic accessory is detachably connected to the lamp holder.

The main control component and the cooling fan are both installed in the receiving cavity, and the cooling fan is electrically connected to the main control component. At least two lamp head assemblies are provided, and each lamp head assembly is mounted on the main body. Each lamp head assembly includes a lamp holder, a connecting hose, an LED light source, and an electrical connection wire.

The LED light source is electrically connected to the main control component via the electrical connection wire. The lamp holder has a mounting cavity with one side open, and the LED light source is installed within this cavity. The open opening allows the light emitted by the LED light source to shine outwards, achieving the fill light effect. Meanwhile, the mounting cavity is connected to the receiving cavity via a connecting channel, forming a heat dissipation channel with an air inlet and an air outlet. When the cooling fan is working, it drives the airflow within the heat dissipation channel and dissipates heat from the LED light source, thus significantly improving the cooling fan's heat dissipation capacity for the LED light source. This allows for the use of high-power LED light sources in close-up shooting fill lights, greatly increasing the brightness of the fill lights and meeting the lighting requirements for close-up shooting, while ensuring the safe operation of the LED light source.

Detailed Implementation

[0027] Typical embodiments embodying the features and advantages of this utility model will be described in detail in the following description. It should be understood that this utility model can have various variations in different embodiments, all of which do not depart from the scope of this utility model, and the descriptions and illustrations therein are for illustrative purposes only and not intended to limit this utility model.

These descriptions are appropriate when these elements are in the positions shown in the accompanying drawings. If the description of the positions of these elements changes, these directional indications will also change accordingly.

[0029] 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 technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the stated features. In the description of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified.

[0030] Because existing close-up shooting fill lights all use natural heat dissipation for their LED light sources, they can only meet the heat dissipation needs of low-power LED light sources. This results in insufficient illumination for close-up shooting and fails to adequately meet the lighting requirements of modern close-up photography. Therefore, a new close-up shooting fill light is proposed to solve the above problems.

[0031] The solution is further illustrated by the following examples: Figure 1 This is a schematic diagram of a close-up shooting fill light and flash unit according to an embodiment of the present invention. Figure 2 yes Figure 1A diagram illustrating a close-up shooting fill light. Figure 3 yes Figure 1 A cross-sectional view of the fill light used for close-up photography. Figure 4 yes Figure 3 A magnified view of point A. Figure 5 yes Figure 3 Enlarged view of point B.

[0032] Please see Figure 1 The lighting system of this embodiment may include a close-up shooting fill light and photographic accessories. The close-up shooting fill light can be connected to a shooting device, such as a camera, camcorder, or video camera, so that the fill light can provide supplementary lighting to the object being photographed, thereby improving the shooting effect.

[0033] Meanwhile, the photography accessories can be detachably connected to the close-up shooting fill light to facilitate the installation or removal of the photography accessories.

[0034] In this embodiment, the photographic accessory can be set as a flash 30, an LED fill light, or a light effect accessory, so that the lighting system can select the appropriate photographic accessory to connect to the close-up shooting fill light according to actual needs, thereby improving the fill light effect and shooting effect.

[0035] It should be noted that the photographic accessories may include multiple flash units 30, and all of the flash units 30 are connected to a close-up shooting fill light. Furthermore, the flash units 30 can also be electrically connected to the close-up shooting fill light, enabling the close-up shooting fill light to provide power to the flash units 30 and allowing the close-up shooting fill light to control the operation of the flash units.

[0036] In this embodiment, the lighting accessories may include optical accessories such as color filters, diffusers, plane mirrors, lenses, and slides, so that the supplementary lighting system can provide supplementary lighting for the object being photographed.

[0037] See Figure 3 , Figure 4 and Figure 5 The close-up shooting fill light may include a main body base 10, a main control component 31, a cooling fan 40, and at least two lamp head components 20.

[0038] The main body 10 can be connected to the shooting device, allowing the close-up shooting fill light to be detachably connected to the shooting device. The lamp head assembly 20 is mounted on the main body 10, so that the main body 10 can support the lamp head assembly 20.

[0039] Specifically, the main body 10 is provided with a receiving cavity 11 and a mounting part 12. The main control component 31 and the cooling fan 40 are installed in the receiving cavity 11, and the cooling fan 40 is electrically connected to the main control component 31. The mounting part 12 is located on the side of the main body 10 opposite to the connection between the lamp head assembly 20 and the main body 10. The mounting part 12 is used for detachably connecting the shooting device, so that the close-up shooting fill light can be detachably connected to the shooting device.

[0040] In this embodiment, the lamp head assembly 20 is detachably connected to the main body 10 to facilitate the installation of the lamp head assembly 20 on the main body 10 or the removal of the lamp head assembly 20 from the main body 10.

[0041] It should be noted that there can be two lamp head assemblies 20, and both lamp head assemblies 20 are connected to the main body 10 and located on the same side of the main body 10.

[0042] In some other embodiments, there may be two or more lamp head assemblies 20, and multiple lamp head assemblies 20 are connected side by side on the same side of the main body 10, so that multiple lamp head assemblies 20 can provide supplementary lighting to the subject, thereby improving the supplementary lighting effect.

[0043] See Figure 4 and Figure 5 The lamp holder assembly 20 may include a lamp holder 21, a connecting hose 22, an LED light source 23, and an electrical connection wire 27.

[0044] Specifically, the lamp holder 21 is connected to the main body 10 via a connecting hose 22, allowing the connecting hose 22 to support the lamp holder 21. Furthermore, the connecting hose 22 is deformable and can be shaped to allow adjustment of the lamp holder 21's position relative to the main body 10, and consequently, its position relative to the subject, ensuring the lamp holder 21 is aligned with the subject for convenient supplemental lighting during close-up photography.

[0045] In this embodiment, the connecting hose 22 can support the weight of the lamp holder 21, allowing the user to adjust the position of the lamp holder 21 relative to the main body 10 by adjusting the deformation of the connecting hose 22. This enables the lamp holder 21 to align with the subject being photographed and provides supplementary lighting for close-up shots, thereby improving the shooting effect. Specifically, the connecting hose 22 can be configured as a shaped hose or a gooseneck tube.

[0046] Furthermore, the lamp holder 21 has a mounting cavity 211 with one side open. The LED light source 23 is installed inside the mounting cavity 211 and is positioned corresponding to the opening 212 of the mounting cavity 211, so that the light emitted by the LED light source 23 can illuminate the outside of the lamp holder 21. Specifically, the opening 212 of the mounting cavity 211 is located on the side away from the connection between the lamp holder 21 and the connector 22, and the opening 212 is the light outlet of the lamp holder 21, thereby facilitating the adjustment of the light emission direction of the lamp head assembly 20.

[0047] In this embodiment, a connecting hose 22 is provided with a connecting channel 221, an electrical connection cable 27 is installed on the connecting channel 221, and the LED light source 23 is electrically connected to the main control component 31 through the electrical connection cable 27.

[0048] Furthermore, the mounting cavity 211 is connected to the receiving cavity 11 via the connecting channel 221 to form a heat dissipation channel. The two ends of the heat dissipation channel are respectively connected to an air inlet 213 and an air outlet 13, enabling the cooling fan 40 to drive airflow within the heat dissipation channel and dissipate heat from the LED light source 23. This ensures that the LED light source 23 operates at a suitable temperature, preventing overheating and potential damage.

[0049] It should be noted that, since the cooling fan 40 can dissipate heat from the LED light source 23, it greatly improves the heat dissipation capacity of the LED light source 23, enabling the use of high-power LED light source 23 for close-up shooting fill lights. This greatly improves the brightness of the close-up shooting fill lights, thereby meeting the fill light requirements for close-up shooting and ensuring the safe operation of the LED light source 23.

[0050] See Figure 4 The LED light source 23 may include an LED lamp body 231, a lamp board 232, and a focusing element 233. The LED lamp body 231 is installed in the mounting cavity 211 and on the lamp board 232, facing the opening 212. The focusing element 233 is housed in the mounting cavity 211 and is located on the side of the lamp board 232 facing the opening 212, so that the focusing element 233 can converge the light emitted by the LED lamp body 231 and illuminate the outside of the mounting cavity 211 from the opening 212, so that the lamp holder 21 can illuminate the subject to achieve supplementary lighting.

[0051] It should be noted that multiple LED lamp bodies 231 can be provided, and multiple LED lamp bodies 231 are spaced apart on the side of the lamp board 232 facing the opening 212 to improve the lighting effect of the LED light source 23. At the same time, the LED lamp bodies 231 can be set as single-color LED beads, dual-color LED beads or RGB beads according to actual needs, so that the light emitted by the LED light source 23 can meet the needs of different scenarios.

[0052] In this embodiment, the opening 212 can be covered by a cover 234 to protect the LED light source 23 inside the mounting cavity 211, preventing debris from outside the lamp holder 21 from entering the mounting cavity 211 and affecting the LED light source 23. Specifically, the cover 234 is a transparent cover so that the light emitted by the LED light source 23 can pass through the cover 234.

[0053] See Figure 4 and Figure 5 An air inlet 213 can be provided on the side wall of the lamp holder 21. The air inlet 213 is connected to the mounting cavity 211 and is set to correspond to the LED light source 23, so that the air entering and exiting the mounting cavity 211 from the air inlet 213 can carry away the heat on the LED light source 23, thereby achieving the cooling of the LED light source 23.

[0054] Meanwhile, a through air outlet 13 is provided on the side wall of the main body 10, which is connected to the accommodating cavity 11, so that the air in the accommodating cavity 11 can enter and exit the accommodating cavity 11 through the air outlet 13, so as to facilitate the flow of air in the accommodating cavity 11.

[0055] In this embodiment, when the cooling fan 40 is working, it drives the air in the heat dissipation channel to flow. Simultaneously, since the lamp holder 21 is provided with an air inlet 213 and the main body 10 is provided with an air outlet 13, the heat dissipation channel connects the air inlet 213 and the air outlet 13. This allows the cooling air drawn in from the air inlet 213 to flow directionally along the mounting cavity 211, the connecting channel 221, and the accommodating cavity 11, dissipating the heat generated by the LED light source 23 in the mounting cavity 211 through the air outlet 13. This heat dissipates and cools the LED light source 23, ensuring its safe operation.

[0056] It should be noted that, since the heat sink 24 can dissipate heat and cool the LED light source 23, the LED light source 23 can operate at a higher power, and can even drive the LED light source 23 to emit a momentary high-brightness flash, so as to achieve a similar fill light effect as a xenon flash.

[0057] Figure 6 yes Figure 1 A close-up view of the fill light from the front. Figure 7 yes Figure 3 Enlarged view of point B.

[0058] See Figure 6 and Figure 7In this embodiment, multiple cooling fans 40 can be provided, and each cooling fan 40 corresponds to one lamp holder assembly 20, so that each cooling fan 40 can dissipate heat from the LED light source 23 in a lamp holder 21, thereby ensuring the heat dissipation effect of the LED light source 23. Specifically, the number of cooling fans 40 is the same as the number of lamp holder assemblies 20, and each cooling fan 40 is provided corresponding to each connecting hose 22, so that each cooling fan 40 drives the airflow in the corresponding connecting channel 221.

[0059] In some other embodiments, multiple lamp holder assemblies 20 may also share the same cooling fan 40, so that the cooling fan 40 can simultaneously dissipate heat from the LED light sources 23 in multiple lamp holders 21.

[0060] It should be noted that since the lamp holder 21 is equipped with a cooling fan 40 to dissipate heat from the LED light source 23, thereby improving the heat dissipation effect of the LED light source 23, the output power of the LED light source 23 can be increased. In some practical scenarios, this allows the close-up shooting fill light to meet the daily close-up shooting needs without the use of the flash 30, thus saving the cost of using the close-up shooting fill light or fill light system and reducing the overall size of the close-up shooting fill light or fill light system, making it easier for users to carry and use.

[0061] Furthermore, since the cooling fan 40 is installed within the receiving cavity 11 of the main body 10, and the receiving cavity 11 is connected to the mounting cavity 211 via the connecting channel 221, the cooling fan 40 can dissipate heat from the LED light source 23, avoiding the need for a heat dissipation structure within the lamp holder 21. This reduces the overall weight of the lamp holder 21 and lessens the burden on the connecting hose 22. Simultaneously, because the overall volume of the main body 10 is larger than that of the lamp holder 21, a high-power cooling fan 40 can be installed within the receiving cavity 11, ensuring overall heat dissipation performance.

[0062] See Figure 2 and Figure 5 The lamp holder 21 may be provided with a connecting part 25. The connecting part 25 is located on the outer periphery of the lamp holder 21, allowing it to be used to mount photographic accessories to improve the fill light effect. Specifically, the connecting part 25 can also be used to mount a flash 30, an LED fill light, or other lighting accessories. Furthermore, the lighting accessories can be color filters, plane mirrors, lenses, and slides to meet the fill light needs of different scenarios.

[0063] Specifically, the connecting part 25 can be configured as a cold shoe, allowing light effect accessories such as diffusers, color filters, plane mirrors, lenses, and projectors to be connected to the connecting part 25 via a mounting bracket. Alternatively, the connecting part 25 can be configured as a hot shoe for mounting the flash unit 30, enabling the flash unit 30 to be electrically connected to the lamp head assembly 20. That is, the connecting part 25 may include a connecting slot 251 and an electrical contact point 252. The connecting slot 251 is used for detachably connecting the flash unit 30, LED fill light, or light effect accessories to hold them in place on the lamp holder 21. The electrical contact point 252 is used for electrically connecting the flash unit 30 or LED fill light, enabling the flash unit 30 or LED fill light to be electrically connected to the lamp head assembly 20.

[0064] In this embodiment, there are two connecting parts 25, and the two connecting parts 25 are disposed on the opposite side walls of the lamp holder 21, so that the lamp holder 21 can connect the flash lamp 30 and the light effect accessory at the same time according to the actual supplementary lighting needs, or connect two flash lamps 30 or LED supplementary lights at the same time, thereby improving the supplementary lighting effect.

[0065] See Figure 3 , Figure 4 and Figure 5 Close-up shooting fill lights may also include a lamp head plate 26.

[0066] Specifically, the lamp holder plate 26 is installed inside the mounting cavity 211 and is located on the side of the heat sink 24 away from the LED light source 23.

[0067] In this embodiment, the lamp head plate 26 is used to electrically connect the LED light source 23 and the electrical contact point 252 to provide power to the LED light source 23 and the flash lamp 30, ensuring the operation of the LED light source 23 and the flash lamp 30.

[0068] See Figure 2 and Figure 5 The close-up shooting fill light may also include a display component 32 and a battery 33.

[0069] Specifically, the main control component 31 and the battery 33 are installed in the accommodating cavity 11, and the main control component 31 is electrically connected to the cooling fan 40 and the battery 33, so that the battery 33 can provide power to the main control component 31.

[0070] Meanwhile, the display component 32 can be equipped with a display screen to display the parameter signal light of the close-up shooting fill light, and the display component 32 is connected to the outer periphery of the main body 10, that is, the display component 32 is connected to the side wall of the main body 10 and is electrically connected to the main control component 31, so that the display component 32 can display control signals.

[0071] It should be noted that the main control component 31 and the lamp head board 26 are electrically connected via an electrical connection cable 27, so that the main control component 31 can provide control signals to the lamp head board 26 through the electrical connection cable 27, thereby controlling the operation of the LED light source 23 and the flash 30. At the same time, the battery 33 can also provide power to the lamp head board 26 through the electrical connection cable 27.

[0072] In this embodiment, the main control component 31 is equipped with a flash control module. The flash control module can control the LED light source 23 to emit a momentary high-brightness flash, so that the LED light source 23 can be used as a flash lamp, thereby improving the fill light effect. Specifically, the flash control module is equipped with a MOSFET (i.e., field-effect transistor). By controlling the on and off of the MOSFET, the LED light source can emit a flash.

[0073] See Figure 2 and Figure 5 The close-up shooting fill light may also include a control component 34.

[0074] The control component 34 is mounted on the side wall of the main body 10 and is located on the same side as the display component 32. The control component 34 is electrically connected to the main control component 31, allowing the operator to input control signals to adjust the supplementary lighting parameters. Specifically, the control component 34 includes buttons and control knobs to facilitate operator input of control signals.

[0075] It should be noted that the display component 32 and the control component 34 are located on the same side of the main body 10, which makes it convenient for operators to read the display information and input control signals through the control component 34.

[0076] In this embodiment, the central axis of the mounting portion 12 is set at an angle to the central axis of the main body base 10. After the main body base 10 is connected to the shooting device, the main body base 10 is tilted, and the side of the main body base 10 where the display component 32 and the control component 34 are mounted is tilted, thereby facilitating the operator to view the display component 32 or operate the control component 34. Specifically, the tilt angle of the main body base 10 relative to the horizontal direction can be set between 30° and 45°, thereby facilitating the operator to view the display component 32 or operate the control component 34.

[0077] In addition, the mounting part 12 is provided with an electrical connector 121 that is electrically connected to the main control component 31. When the mounting part 12 is connected to the shooting device, the shooting device can be electrically connected to the main control component 31 through the electrical connector 121, thereby enabling the shooting device to send control signals or provide power to the main control component 31, thus ensuring the operation of the close-up shooting fill light.

[0078] In summary, the close-up shooting fill light includes a main body 10, a main control component 31, a cooling fan 40, and a lamp head assembly 20. The main body 10 has a receiving cavity 11 and a mounting part 12. The main body 10 is connected to the shooting equipment through the mounting part 12. The main control component 31 and the cooling fan 40 are both installed in the receiving cavity 11, and the cooling fan 40 is electrically connected to the main control component 31. At least two lamp head assemblies 20 are provided, and the lamp head assemblies 20 are installed on the main body 10. The lamp head assembly 20 includes a lamp holder 21, a connecting hose 22, an LED light source 23, and an electrical connection wire 27. The lamp holder 21 is connected to the main body 10 through the connecting hose 22, so that the connecting hose 22 can support the lamp holder 21, and the connecting hose 22 can deform and be shaped to adjust the position of the lamp holder 21 relative to the main body 10. The connecting hose 22 has a connecting channel 221, and the electrical connecting wire 27 is housed in the connecting channel 221. The LED light source is electrically connected to the main control component 31 through the electrical connecting wire 27. The lamp holder 21 has a mounting cavity 211 with one side open. The LED light source 23 is installed in the mounting cavity 211 and faces the opening 212, so that the light emitted by the LED light source 23 can shine outward to achieve the effect of supplemental lighting.

[0079] Meanwhile, the main body 10 has a receiving cavity 11, and the cooling fan 40 is installed inside the receiving cavity 11. A connecting channel 221 is provided inside the connecting hose 22, allowing the mounting cavity 211 to connect to the receiving cavity 11 through the connecting channel 221, forming a heat dissipation channel. An air inlet 213 and an air outlet 13 are connected within the heat dissipation channel. When the cooling fan 40 is working, it drives airflow within the mounting cavity 211, the connecting channel 221, and the heat dissipation channel within the receiving cavity 11, thus dissipating heat from the LED light source. This significantly improves the heat dissipation capacity of the cooling fan 40 for the LED light source, allowing the use of high-power LED light sources for close-up shooting. This greatly improves the brightness of the close-up shooting fill light, effectively meeting the current lighting requirements for close-up shooting, and ensuring the safe operation of the LED light source. This prevents the light source from overheating during operation, ensuring that it can operate at high power and guaranteeing its own safety.
