[0045] 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 can have various changes in different embodiments without departing from the scope of the present invention, and the descriptions and illustrations therein are essentially for illustrative purposes rather than for limiting the present invention.

[0046] In the description of the present application, it should be understood that in the embodiments shown in the drawings, the indications of directions or positional relationships (such as up, down, left, right, front and back, etc.) are only for the convenience of describing the present application and simplifying the description, rather than indicating or implying that the devices or elements referred to must have a specific orientation, be constructed and operate in a specific orientation. 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 also change accordingly.

[0047] In addition, the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Thus, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of this application, the meaning of "plurality" is two or more, unless otherwise clearly and specifically defined.

[0048] See also Figure 1 and Figure 2As shown, the portable photography light 10 according to the embodiment of the utility model comprises a light body 100 and a power supply mounting plate 200. The light body 100 is provided with a light source part 110 and a built-in power source part 120, and the built-in power source part 120 is used to supply power to the light source part 110.

[0049] The power supply mounting plate 200 is detachably connected to the lamp body 100, and a power supply mounting position 210 for mounting the external power supply 20 is provided on the power supply mounting plate 200. A first electrical connection portion 130 is provided on the lamp body 100, and a second electrical connection portion 220 is provided on the power supply mounting plate 200. When the power supply mounting plate 200 is connected to the lamp body 100, the first electrical connection portion 130 is conductively connected to the second electrical connection portion 220. A third electrical connection portion 230 for conductively connecting to the external power supply 20 is provided at the power supply mounting position 210, and the third electrical connection portion 230 is conductively connected to the second electrical connection portion 220, so that the external power supply 20 can supply power to the light source portion 110.

[0050] The lamp body 100 may be substantially cylindrical in structure. The lamp body 100 may include a lamp housing, which is hollow inside to accommodate the light source unit 110 and the built-in power supply unit 120. Other components such as a main control board and a heat dissipation structure may also be installed in the lamp housing, which is not limited in the present application.

[0051] like Figure 3 and Figure 4 As shown, one end of the lamp housing has an opening, and the light source unit 110 is disposed in the lamp housing near the opening. The light emitted by the light source unit 110 can be emitted outward through the opening. The light source unit 110 can be an LED light source or a COB light source, etc.

[0052] like Figure 2 As shown, the power supply mounting plate 200 is disposed at the other end of the lamp housing, and the power supply mounting plate 200 can be opposite to the light source unit 110. In this embodiment, the power supply mounting plate 200 and the light source unit 110 are respectively disposed at opposite ends of the lamp body 100, so that the distance between the power supply mounting plate 200 and the light source unit 110 is relatively far. Therefore, when the external power supply 20 is mounted on the power supply mounting plate 200, the distance between the external power supply 20 and the light source unit 110 is relatively far, thereby reducing the influence of the heat generated by the external power supply 20 when working on the light source unit 110, ensuring the stable operation of the light source unit 110, and extending the service life of the light source unit 110. Therefore, the portable video light 10 of the present application can work more stably and have a longer service life.

[0053] See also Figure 1For the convenience of description, it is now stipulated that the end where the light source part 110 is located is the front end of the lamp body 100, and the end where the power supply mounting plate 200 is located is the rear end of the lamp body 100. And the front-to-back direction of the lamp body 100 is the axial direction of the lamp body 100. In addition, along the front-to-back direction of the lamp body 100, the surface of the power supply mounting plate 200 that contacts the lamp body 100 is the front end surface of the power supply mounting plate 200, and the surface of the power supply mounting plate 200 that faces away from the lamp body 100 is the rear end surface of the power supply mounting plate 200.

[0054] like Figure 2 As shown, the built-in power supply unit 120 is disposed between the power supply mounting plate 200 and the light source unit 110. Specifically, the built-in power supply unit 120 is disposed in an internal cavity between the front and rear ends of the lamp housing.

[0055] See also Figure 3 In one embodiment, the built-in power supply unit 120 is arranged near the rear end of the lamp body 100. By arranging the built-in power supply unit 120 near the rear end of the lamp body 100, the distance between the built-in power supply unit 120 and the light source unit 110 is relatively far, thereby reducing the influence of the heat generated by the built-in power supply unit 120 when working on the light source unit 110, ensuring the stable operation of the light source unit 110, and extending the service life of the light source unit 110, thereby improving the working stability of the portable video light 10 and extending its service life.

[0056] See also Figure 6 In one embodiment, the built-in power supply unit 120 is a removable rechargeable battery. The built-in power supply unit 120 in this embodiment is a removable battery structure. The battery can be a common rechargeable lithium battery, and this application does not limit this. When the battery is exhausted, the user can remove the built-in power supply unit 120 for charging or directly replace the battery, so that the portable video light 10 can be used in various usage environments and will not be unable to be used due to insufficient power.

[0057] For example, the built-in power supply unit 120 may include a battery housing, and a rechargeable lithium battery is installed in the battery housing. In this example, the battery housing and the rechargeable lithium battery constitute the built-in power supply unit 120, and the built-in power supply unit 120 can be quickly disassembled and replaced by the detachable connection between the battery housing and the lamp housing.

[0058] See also Figure 6 As shown, in one embodiment, a receiving cavity 160 for receiving the built-in power supply unit 120 is provided on the lamp body 100, and the receiving cavity 160 has an opening toward any side of the circumference of the lamp body 100. By providing the receiving cavity 160 with an opening, the installation and removal of the built-in power supply unit 120 can be facilitated, making the use of the portable video light 10 more convenient.

[0059] In some other embodiments, the built-in power supply unit 120 may also be fixedly installed inside the lamp body 100. The built-in power supply unit 120 may include a rechargeable lithium battery. When the battery needs to be charged, it can be charged through a charging interface provided on the lamp body 100.

[0060] See also Figure 4 , the power supply mounting plate 200 is detachably connected to the rear end of the lamp body 100. In one embodiment, an anti-skid structure 170 is provided on the surface of the lamp body 100 for mounting the power supply mounting plate 200. That is, an anti-skid structure 170 is provided on the rear end surface of the lamp body 100. The anti-skid structure 170 may be an anti-skid pattern. Alternatively, the anti-skid structure 170 may be a roughened surface. By providing the anti-skid structure 170, the contact friction between the lamp body 100 and the power supply mounting plate 200 may be increased, so that the lamp body 100 and the power supply mounting plate 200 are more tightly connected.

[0061] See also Figure 4 and Figure 5 In one embodiment, a connection groove 140 is provided on the lamp body 100, and a connection block 240 is provided on the power supply mounting plate 200 corresponding to the connection groove 140. The connection block 240 can be inserted into the connection groove 140, so that the power supply mounting plate 200 can be detachably connected to the lamp body 100.

[0062] Specifically, the connection groove 140 may be provided on the circumferential outer surface of the rear end of the lamp body 100. The connection groove 140 may be a U-shaped groove. The U-shaped connection groove 140 may be arranged parallel to the rear end surface of the lamp body 100.

[0063] The connection block 240 may be provided to protrude from the front end surface of the power supply mounting plate 200. The connection block 240 may be provided at the edge of the power supply mounting plate 200. The connection block 240 may have a U-shape.

[0064] When the power supply mounting plate 200 needs to be connected to the lamp body 100, the connecting block 240 of the power supply mounting plate 200 is aligned with the connecting groove 140 and slid in so that the U-shaped connecting block 240 is fully snapped into the U-shaped connecting groove 140, thereby the power supply mounting plate 200 is detachably fixed to the lamp body 100.

[0065] In other embodiments, the connection groove 140 may also be a long strip groove. Two long strip grooves may be provided, and the two long strip grooves are respectively parallel to the rear end surface of the lamp body 100 and are provided on the opposite two sides of the rear end of the lamp body 100. Correspondingly, the connection block 240 may be two long strip convex ribs provided on the opposite sides of the front end surface of the power supply mounting plate 200.

[0066] It can be understood that in some other embodiments, the positions of the connection slot 140 and the connection block 240 can be interchanged. That is, the connection slot 140 is arranged on the power supply mounting plate 200. The connection block 240 can be correspondingly arranged on the lamp body 100.

[0067] In the embodiment of the present application, the power supply mounting plate 200 and the lamp body 100 are detachably connected by the snap fit between the connecting block 240 and the connecting groove 140. However, the present application is not limited thereto, and in some other embodiments, the power supply mounting plate 200 can also be detachably connected to the lamp body 100 by a magnetic structure, a screw structure, or a snap structure.

[0068] See also Figure 4 and Figure 5 In one embodiment, a locking portion 150 is provided on the lamp body 100, and the locking portion 150 is movably disposed on one side of the connecting groove 140. A locking hole 250 is provided on the connecting block 240 corresponding to the locking portion 150. When the power supply mounting plate 200 is connected to the lamp body 100, the locking portion 150 can be inserted into the locking hole 250, so that the power supply mounting plate 200 remains fixed on the lamp body 100.

[0069] The locking portion 150 may be slidably connected to one side of the lamp body 100 and located at one side of the connecting groove 140. The locking portion 150 can slide toward the connecting groove 140 so that its end can extend into the connecting groove 140. When the power supply mounting plate 200 needs to be connected to the lamp body 100, the connecting block 240 of the power supply mounting plate 200 is aligned with the connecting groove 140 and slides into the connecting groove 140 so that the U-shaped connecting block 240 is completely snapped into the U-shaped connecting groove 140. Then, the locking portion 150 is moved toward the connecting groove 140 so that its end extends into the connecting groove 140 and snaps into the locking hole 250, so that the power supply mounting plate 200 cannot slide relative to the lamp body 100, thereby ensuring a reliable connection between the power supply mounting plate 200 and the lamp body 100.

[0070] The sliding of the locking part 150 can be operated manually. When the power supply mounting plate 200 is connected to the lamp body 100, the locking part 150 is manually moved so that its end is inserted into the locking hole 250, and the power supply mounting plate 200 can be kept fixed on the lamp body 100; when the power supply mounting plate 200 needs to be removed from the lamp body 100, the locking part 150 is manually moved so that its end is removed from the locking hole 250, and the power supply mounting plate 200 can slide relative to the lamp body 100 and be removed.

[0071] Alternatively, the sliding of the locking portion 150 can also be automatically achieved by using an elastic member such as a spring. For example, the spring is arranged between the locking portion 150 and the lamp housing of the lamp body 100, and the locking portion 150 can move toward the connecting groove 140 under the elastic action of the spring. When the power supply mounting plate 200 is connected to the lamp body 100, the locking portion 150 moves toward the connecting groove 140 under the elastic action of the spring, and its end is stuck in the lock hole 250, and the power supply mounting plate 200 can remain fixed on the lamp body 100; when the power supply mounting plate 200 needs to be removed from the lamp body 100, the user moves the power supply mounting plate 200 to slide relative to the lamp body 100 to squeeze the locking portion 150, and when the locking portion 150 is squeezed, its end can exit the lock hole 250, so that the power supply mounting plate 200 can be smoothly removed.

[0072] As shown in the figure, in one embodiment, the first electrical connection portion 130 is a first electrical contact disposed in the connection slot 140, and the second electrical connection portion 220 is a second electrical contact disposed on the connection block 240 corresponding to the first electrical contact. When the power supply mounting plate 200 and the lamp body 100 are connected in place through the snap fit of the connection block 240 and the connection slot 140, the first electrical contact and the second electrical contact are butted against each other for electrical conduction.

[0073] In other embodiments, the first electrical contact and the second electrical contact may also be respectively disposed on the rear end surface of the lamp body 100 and the front end surface of the power supply mounting plate 200. When the power supply mounting plate 200 and the lamp body 100 are connected in place by the snap fit of the connecting block 240 and the connecting groove 140, the first electrical contact and the second electrical contact can be connected and electrically conductive, and the external power supply 20 can supply power to the lamp body 100 through the first electrical connection portion 130 and the second electrical connection portion 220.

[0074] In the embodiment of the present application, the first electrical connection part 130 and the second electrical connection part 220 may be contact-type electrical contacts that can be adapted to be electrically connected to each other. However, the present application is not limited thereto. In other embodiments, the first electrical connection part 130 and the second electrical connection part 220 may also be plug-in terminals that can be adapted to be electrically connected to each other. Alternatively, the first electrical connection part 130 and the second electrical connection part 220 may be conductive probes and metal contacts that can be adapted to be electrically connected to each other.

[0075] The portable photography light 10 of the embodiment of the present application has a power supply mounting plate 200 for mounting an external power supply 20. Figure 6 As shown, a power supply mounting position 210 for mounting an external power supply 20 is provided on the power supply mounting plate 200. The power supply mounting position 210 is arranged on the rear end surface of the power supply mounting plate 200. The number of the power supply mounting positions 210 on the power supply mounting plate 200 can be one or two, or even more than two.

[0076] When one power supply mounting position 210 is provided on the power supply mounting plate 200, it can be suitable for mounting a larger external power supply 20. When two power supply mounting positions 210 are provided on the power supply mounting plate 200, two smaller external power supplies 20 can be mounted on the two power supply mounting positions 210, respectively. Thus, external power supplies 20 of various specifications can supply power to the lamp body 100 through the power supply mounting plate 200, effectively improving the application range of the portable video light 10 and ensuring that the portable video light 10 can work outdoors for a long time.

[0077] In the embodiment of the present application, each power supply installation position 210 can be installed with an external power supply 20. Figure 6 As shown, each power supply installation position 210 is provided with a third electrical connection portion 230 for conductive connection with the external power supply 20. In the embodiment of the present application, the third electrical connection portion 230 may be a conductive probe that can be adapted to be electrically connected with the external power supply 20.

[0078] In other embodiments, the third electrical connection portion 230 may be a contact-type electrical contact adapted to be electrically connected to the external power source 20. Alternatively, the third electrical connection portion 230 may be a plug-in terminal adapted to be electrically connected to the external power source 20.

[0079] The third electrical connection part 230 is conductively connected to the second electrical connection part 220. Therefore, the external power supply 20 can supply power to the lamp body 100 through the conductive connection of the third electrical connection part 230, the second electrical connection part 220 and the first electrical connection part 130. For example, the power supply mounting plate 200 may include a housing and a control circuit board, the control circuit board is disposed in the housing, and the second electrical connection part 220 and the third electrical connection part 230 are both electrically connected to the control circuit board. In other embodiments, the second electrical connection part 220 and the third electrical connection part 230 may also be electrically connected using a cable.

[0080] The external power supply 20 installed on the power supply mounting plate 200 may be a power supply of various specifications.

[0081] In one embodiment, the external power source 20 and the internal power source 120 may be power sources of the same specification. For example, when the internal power source 120 is a dedicated lithium battery for the photography light, the external power source 20 may also be a dedicated lithium battery for the photography light.

[0082] When a power supply of the same specification and model as the built-in power supply unit 120 is installed on the power supply mounting plate 200, the photographic light does not need to stop working when the external power supply 20 is replaced to avoid interrupting the shooting work, thereby effectively ensuring the smooth progress of the shooting work.

[0083] Alternatively, the external power source 20 and the internal power source 120 may be power sources of different specifications. For example, when the internal power source 120 uses a dedicated lithium battery for the present photography light, the external power source 20 uses a lithium battery from other electronic devices. For example, the external power source 20 may use a camera lithium battery of a common brand on the market. Alternatively, the external power source 20 may use an external lithium battery commonly used in large photography lights or electric photography accessories on the market.

[0084] In one embodiment, a transformer is provided on the power supply mounting plate 200, and the transformer is used to convert the voltage of the external power supply 20 into the same voltage as the internal power supply unit 120. The transformer can be provided on the control circuit board inside the power supply mounting plate 200. By providing the transformer, external power supplies 20 of various specifications can all supply power to the lamp body 100 through the power supply mounting plate 200, thereby increasing the application range of the portable video light 10 and effectively ensuring that the portable video light 10 can work outdoors for a long time.

[0085] It is worth noting that in the embodiment of the present application, only one specification of external power supply 20 can be installed on one power supply mounting plate 200. That is, one power supply mounting plate 200 can only be used to install a rechargeable lithium battery; or one power supply mounting plate 200 can only be used to install a camera lithium battery or a photography light lithium battery.

[0086] In the embodiment of the present application, the structures of the power supply installation positions 210 on each power supply installation board 200 are the same. Therefore, one power supply installation board 200 can only be used to install an external power supply 20 of one specification.

[0087] In the embodiment of the present application, the structures of the power supply installation positions 210 on different power supply installation boards 200 are different from each other. Therefore, a plurality of different power supply installation boards 200 can be used to install external power supplies 20 of different specifications.

[0088] It is worth noting that, since the power supply installation position 210 on the same power supply installation board 200 can only install an external power supply 20 of a predetermined specification, the voltage value of the external power supply 20 installed in the power supply installation board 200 is predictable. At the same time, since the voltage of the built-in power supply unit 120 is also known, the parameters of the transformer in the power supply installation board 200 can also be determined accordingly. That is, the parameters of the transformers in different power supply installation boards 200 are also different from each other, so that external power supplies 20 of different specifications can stably and reliably supply power to the lamp body 100 through different power supply installation boards 200; if the output voltage of the external power supply 20 allowed to be installed on the power supply installation board 200 is consistent with the voltage of the built-in power supply unit 120, then there is no need to provide a transformer on the power supply installation board 200.

[0089] See also Figure 6As shown, in one embodiment, a fixing structure 260 for fixing the external power source 20 is provided on the power source mounting plate 200. Exemplarily, the fixing structure 260 includes a plurality of fixing protrusions 261 provided in the power source mounting position 210, and each fixing protrusion 261 is used to engage with the bayonet 201 on the external power source 20. In this embodiment, the power source mounting plate 200 is suitable for fixing and installing a camera battery. In the case that the built-in power source unit 120 is out of power, the backup battery of the camera equipment at the shooting site can be used to power the photography light, so as to ensure the smooth progress of the photography work.

[0090] like Figure 6 As shown in the example, the fixing structure 260 in the power supply installation position 210 on the power supply installation board 200 is set according to the assembly structure of the battery of the Sony camera. If the battery is replaced with a Canon camera, a Nikon camera, etc., it cannot be installed. In this case, it is necessary to replace the power supply installation board 200 with a power supply installation position 210 suitable for installing the Canon camera battery. In this example, since the camera battery is generally small in size, in order to better utilize the area of ​​the power supply installation board 200, two power supply installation positions 210 can be provided on the power supply installation board 200.

[0091] See also Figure 7 and Figure 8 In another embodiment, the fixing structure 260 includes a fixing seat 262 disposed in the power supply mounting position 210, and a fixing slot 263 with a gradually changing opening is formed on the fixing seat 262, and the fixing slot 263 is used to engage with the protrusion on the external power supply 20. The opening of the fixing slot 263 may be in a shape that is larger at the top and smaller at the bottom along the gravity direction. The fixing slot 263 can make the external power supply 20 and the power supply mounting plate 200 tightly connected.

[0092] In this embodiment, the power supply mounting plate 200 can be used to fix and install the batteries of the photographic lights or electric photographic accessories. Specifically, the batteries of the existing large-scale photographic lights or some electric photographic accessories (such as electric lamp holders) are relatively large in size and suitable for being hung on the outside of the device. Therefore, in this example, the fixed structure 260 at the power supply mounting position 210 is arranged according to the assembly structure of the batteries of the large-scale photographic lights or some electric photographic accessories, so that the power supply mounting plate 200 can be used to install the batteries of the large-scale photographic lights or some electric photographic accessories. In the event that the built-in power supply unit 120 is out of power, the spare batteries of other photographic light equipment or photographic accessories at the shooting site can be used to power the portable photographic light 10 to ensure the smooth progress of the photographic work.

[0093] See also Fig. 9 and Fig.10In another embodiment, the fixing structure 260 includes a connecting plate 264 protruding from the rear end surface of the power supply mounting plate 200. The connecting plate 264 can enclose a roughly rectangular power supply mounting position 210. In this embodiment, the external power supply 20 can be a detachable rechargeable lithium battery of the same specification as the built-in power supply unit 120. The external power supply 20 can have a roughly rectangular block shape. The external power supply 20 can be tightly inserted into the power supply mounting position 210 formed by the connecting plate 264 to achieve fixation.

[0094] It can be understood that the external power supply 20 can be a battery structure of various specifications. The voltage and structure of batteries of various specifications are fixed and different from each other. Therefore, in the embodiment of the present application, by designing the fixed structure 260 on the power installation board 200 as a structure suitable for fixing and installing batteries of various devices, one power installation board 200 can be installed with a battery of an electronic device. At the same time, in order to meet the power supply voltage requirements of the lamp body 100, by providing transformers with corresponding parameters on power installation boards 200 of different structures, external power supplies 20 of various specifications can supply power to the lamp body 100.

[0095] When the built-in power supply unit 120 of the portable video light 10 runs out of power, the backup batteries of other equipment at the shooting site can be used to power the portable video light 10, thereby ensuring the smooth progress of the photography work and eliminating the need to carry too many backup batteries, which greatly facilitates outdoor photography.

[0096] In one embodiment of the present invention, a video light system is provided, which includes the portable video light 10 described in any of the above embodiments. The portable video light 10 includes at least two power supply mounting plates 200, and the power supply mounting positions 210 in each power supply mounting plate 200 are different from each other, and are respectively used to fix and install external power supplies 20 of different specifications.

[0097] In the video light system of this embodiment, the portable video light 10 includes a light body 100 and at least two power supply mounting plates 200. The at least two power supply mounting plates 200 can be used to fix and mount more than two external power supplies 20, respectively.

[0098] By configuring the lamp body 100 with at least two power supply mounting plates 200, the portable video light 10 can use at least two specifications of external power supplies 20. When the built-in power supply unit 120 of the portable video light 10 runs out of power, the backup batteries of other electronic devices at the shooting site can be used to power it. This ensures that the photography work can proceed smoothly, and only a few power supply mounting plates 200 with different structures need to be carried, without carrying too many specifications of backup batteries, which greatly facilitates outdoor photography.

[0099] The above embodiments are merely exemplary descriptions of the structures. The structures in the embodiments are not fixed combination structures. In the absence of structural conflicts, the structures in multiple embodiments can be used in any combination.
