[0037] With the continuous development of photography technology, photographers have higher and higher requirements for lighting effects, so various video lights have emerged, such as video lights with built-in batteries. Such video lights are equipped with a battery compartment, and a removable battery is arranged in the battery compartment. When the battery power is low, a new battery can be replaced to ensure continuous power supply to the video light.

[0038] At present, there are many types of video lights and their corresponding batteries. The power of different types of video lights and their internal batteries is also different. In an emergency, batteries of different video lights may be mixed, which will result in a mismatch between the power required by the video light and the rated power of the battery. The actual output power of the battery is often affected by the video light. For example, the rated power of the mixed battery is lower than the power required by the video light. Under the influence of the control circuit in the video light, the actual output power of the battery will be higher than its rated power. Continuous high-power output will cause the battery to generate a lot of heat, and the battery is prone to overheating and damage, which affects the battery life.

[0039] Based on this, the present application provides a power supply component to solve the above-mentioned problem.

[0040] Please also read Figures 1 to 4 , the power supply assembly provided in the embodiment of the present application is now described. The power supply assembly includes a battery compartment 1 and a battery 2 detachably installed in the battery compartment 1, the battery compartment 1 has a power controller (not shown in the figure) and a first induction member 12 electrically connected to the power controller, the power controller is also electrically connected to the battery 2, and a second induction member 22 is provided on the battery 2, and the first induction member 12 is used to sense the second induction member 22, so that the power controller adjusts the output power of the battery 2.

[0041] In the present application, when the battery 2 is installed in the battery compartment 1 , the power controller on the battery compartment 1 can form an electrical connection with the battery 2 . At this time, the power controller can control the output power of the battery 2 .

[0042] By setting a first sensing element 12 on the battery compartment 1 and a second sensing element 22 on the battery 2, the first sensing element 12 and the second sensing element 22 are used together, and the first sensing element 12 is used to sense the second sensing element 22, thereby judging whether the battery 2 carries the second sensing element 22, and further judging whether the battery 2 and the battery compartment 1 are matched, and feeding back the information to the power controller, the power controller adjusts the output power of the battery 2. For example, when the battery and the battery compartment 1 are mixed, the first sensing element 12 on the battery compartment 1 cannot sense the second sensing element 22, and judges that the battery is a non-matching battery. Then, the power controller can control the battery to be at a lower output power. state, when the battery 2 is used in its paired battery compartment 1, the first sensing element 12 on the battery compartment 1 can sense the second sensing element 22, and the first sensing element 12 determines that the battery 2 is a matched battery 2, and the power controller can control the battery 2 to be in a higher output power state; the coordinated use of the first sensing element 12, the second sensing element 22 and the power controller can adjust the output power of the battery 2 according to the matching situation of the battery 2 and the battery compartment 1, reducing the risk of the actual output power of the battery 2 being higher than its rated power, thereby reducing the heat generated by the battery 2 during use, and then reducing the heat accumulation in the battery 2, reducing the probability of the battery 2 being damaged due to overheating, and helping to increase the life of the battery 2.

[0043] In some embodiments, one of the first induction member 12 and the second induction member 22 is a magnetic induction member, and the other of the first induction member 12 and the second induction member 22 is a magnetic element. For example, the first induction member 12 is a magnetic induction member, and the second induction member 22 is a magnetic element, or the second induction member 22 is a magnetic induction member, and the first induction member 12 is a magnetic element. Take the first induction member 12 as a magnetic induction member and the second induction member 22 as a magnetic element as an example for explanation: by setting the first induction member 12 as a magnetic induction member and the second induction member 22 as a magnetic element, the first induction member 12 and the second induction member 22 can be identified by magnetism. It can be understood that there is a magnetic field around the magnetic element. After installation, even if there is a distance between the first induction member 12 and the second induction member 22, as long as the first induction member 12 enters the magnetic field range of the second induction member 22, the first induction member 12 can identify the second induction member 22, thereby determining whether the battery 2 matches the battery compartment 1, and feeding back the information to the power controller, so that the power controller in the battery compartment 1 can quickly respond and adjust the power limit of the battery 2. Taking the second sensing part 22 as a magnetic sensing part and the first sensing part 12 as a magnetic element as an example for explanation: after the magnetic induction of the first sensing part 12 and the second sensing part 22, the first sensing part 12 as a magnetic element can produce a certain position offset under the action of magnetism, triggering the power controller (or generating relevant signals through the trigger control circuit and transmitting them to the power controller), so that the power controller in the battery compartment 1 can respond quickly and adjust the power limit of the battery 2.

[0044] The magnetic sensing element may be a magnetic switch, and the magnetic element may be a magnet. In a specific embodiment, the first sensing element 12 is a magnetic switch, and the second sensing element 22 is a magnet. It is understandable that the magnet itself has magnetism, and if the second sensing element 22 is set as a magnet, then the second sensing element 22 does not need to be electrically connected to the circuit in the battery 2, which can simplify the structure of the battery 2. In this embodiment, the first sensing element 12 is a magnetic switch, and the magnetic switch may be a reed switch, a Hall switch, etc., for example.

[0045] Of course, the first sensing element 12 and the second sensing element 22 are not limited to magnetic elements. In one embodiment, the first sensing element 12 on the battery compartment 1 can be a photoelectric switch, and the second sensing element 22 on the battery 2 can be a baffle. The photoelectric switch and the baffle are used in conjunction with each other. When the baffle blocks the photoelectric switch, the first sensing element 12 can identify and judge the second sensing element 22, thereby allowing the power controller to adjust its control over the output power of the battery 2.

[0046] In another embodiment, the first sensing element 12 on the battery compartment 1 can be two metal contacts electrically connected to the power controller, and the second sensing element 22 on the battery 2 can be a wire. When the two ends of the wire are respectively connected to the two metal contacts, the two metal contacts will be short-circuited, so that the first sensing element 12 can generate a corresponding signal to be transmitted to the power controller; in other embodiments, other structural methods can also be used, which will not be elaborated in this embodiment.

[0047] In some embodiments, reference Figure 3 and Figure 4 ,in Figure 4 This is a simplified cross-sectional schematic diagram of the power supply component of the present application. The battery compartment 1 includes a shell 11, a first cavity 111 is provided in the shell 11, the power controller and the first induction member 12 are both provided in the first cavity 111, a receiving groove 112 is provided in a recessed manner on the surface of the shell 11, and the battery 2 is provided in the receiving groove 112. By providing the receiving groove 112 on the surface of the shell 11, a space for installing the battery 2 can be provided, and the battery 2 is provided in the receiving groove 112, which can also facilitate the positioning between the battery 2 and the battery compartment 1; the power controller and the first induction member 12 are both provided in the first cavity 111 of the shell 11, and the shell 11 can protect the power controller and the first induction member 12, and the power controller and the first induction member 12 will not be exposed, so that the power controller and the first induction member 12 can be prevented from being hit, which helps to increase the service life of both.

[0048] In some embodiments, a second cavity 21 is provided in the battery 2, and a second sensing element 22 is provided in the second cavity 21. By providing the second sensing element 22 in the second cavity 21 of the battery 2, it is also possible to prevent the second sensing element 22 from being exposed, thereby reducing the risk of the second sensing element 22 falling off due to an accidental collision, thereby ensuring that the battery compartment 1 can accurately identify the information of the battery 2.

[0049] Reference Figure 4 A first sensing element 12 is disposed on the cavity wall of the first cavity 111 close to the bottom wall of the receiving groove 112 , the battery 2 has a first side surface 23 that is in contact with the bottom wall of the receiving groove 112 , and a second sensing element 22 is disposed on the cavity wall of the second cavity 21 close to the first side surface 23 .

[0050] In this embodiment, the first side surface 23 of the battery 2 is fitted with the side wall of the accommodating groove 112, and the first sensing element 12 is arranged on the cavity wall of the first cavity 111 close to the bottom wall of the accommodating groove 112, and the second sensing element 22 is arranged on the cavity wall of the second cavity 21 close to the first side surface 23. This can make the distance between the first sensing element 12 and the second sensing element 22 closer, so that the first sensing element 12 can quickly identify and judge the information of the battery 2, and then feed the information back to the power controller, so that the battery compartment 1 can accurately control the output power of the battery 2.

[0051] Reference Figure 7 and Figure 8 , a plurality of first sensing elements 12 are provided, and a first sensing element 12 is further provided on the cavity wall of the first cavity 111 close to the side wall of the receiving groove 112. By providing a plurality of first sensing elements 12, as long as one first sensing element 12 senses the information of the second sensing element 22, the first sensing element 12 can identify and judge the information of the battery 2, and thus feed the information back to the power controller, so that the sensitivity of the battery compartment 1 to the power control of the battery 2 can be improved.

[0052] Reference Figure 5 In one embodiment, the battery 2 has a second side surface 24 that is in contact with the side wall of the receiving groove 112, and a second sensing element 22 is provided, and the second sensing element 22 is located in the angle region between the first side surface 23 and the second side surface 24. By arranging the second sensing element 22 to be located in the angle region between the first side surface 23 and the second side surface 24, the second sensing element 22 can be adjacent to the first side surface 23 and the second side surface 24 at the same time, that is, the second sensing element 22 is adjacent to the bottom wall and the side wall of the receiving groove 112 at the same time. When the battery 2 is installed in the battery compartment 1, the first sensing element 12 on the first cavity 111 close to the side wall of the receiving groove 112 and close to the bottom wall of the receiving groove 112 can enter the magnetic field region of the second sensing element 22, so that multiple first sensing elements 12 can recognize a single second sensing element 22, which can reduce the number of second sensing elements 22 and reduce the cost of the battery 2.

[0053] Reference Figure 6 In another embodiment, the battery 2 has a second side surface 24 that is in contact with the side wall of the receiving groove 112, and a plurality of second sensing members 22 are provided. The second sensing member 22 is provided on the cavity wall of the second cavity 21 near the second side surface 24. In this embodiment, a plurality of second sensing members 22 are provided, and the second sensing members 22 can correspond to the first sensing members 12 one by one. The plurality of second sensing members 22 can generate a plurality of magnetic fields, which is equivalent to increasing the total magnetic field range of the battery 2, and thus can also improve the power control response speed of the battery compartment 1 to the battery 2 and the accuracy of identifying the battery 2.

[0054] Reference Figure 4 and Figure 5 The space of the second cavity 21 in the battery 2 can be equal to the volume of the second sensing element 22. Figure 6 , the space of the second cavity 21 may be larger than the volume of the second sensing element 22 .

[0055] Reference Figure 7 and Figure 8 The surface of the battery 2 is provided with an identification area 25, and the identification area 25 is used to identify the position of the second sensor 22. By providing the identification area 25 on the surface of the battery 2, it is convenient for the staff to determine whether the battery 2 matches the battery compartment 1, so as to facilitate the staff to replace the battery 2.

[0056] In this embodiment, a groove is provided in the identification area 25 . In other embodiments, a text identification, a pattern identification or a color identification may be provided on the surface of the battery 2 .

[0057] Reference Figure 3 and Figure 8 The battery 2 and the battery compartment 1 are snap-fitted together, and a plurality of buckles 113 are provided on the receiving groove 112 of the battery compartment 1. A snap-fit ​​groove 26 is provided on the battery 2, and the buckle 113 is inserted into the snap-fit ​​groove 26, so that the battery 2 and the battery compartment 1 can be stably connected.

[0058] A conductive connector 13 is also provided in the receiving groove 112 of the battery compartment 1. The conductive connector 13 is used to connect to the electrode of the battery 2 to form electrical conduction. In the present embodiment, the conductive connector 13 is electrically connected to the first induction element 12 and the power controller in the battery compartment 1, thereby transferring the electrical energy of the battery 2 to the first induction element 12 and the power controller, so that the battery 2 can supply power to the first induction element 12 and the power controller.

[0059] In the present embodiment, the power controller is powered by a battery 2 connected to the battery compartment 1. When the battery 2 and the battery compartment 1 are just installed and the power supply operation is performed, the power controller is powered on and is in an initial state. The power controller limits the power of the battery 2 so that the battery 2 is in a lower output power state. When the power controller receives a signal from the first sensor 12, the power controller can adjust the power limit on the battery 2 so that the battery 2 can be in a higher output power state. In other embodiments, a power supply component (which can be a battery other than the battery 2 in the present embodiment) can be built into the first cavity 111 of the shell 11, and the power controller is powered by the built-in power supply component. Then, during the process of installing the battery 2 into the battery compartment 1, the first sensor 12 enters the magnetic field range of the second sensor 22 and identifies the information of the battery 2, and then transmits the information to the power controller through the circuit. After receiving the information, the power controller can adjust the power control of the battery 2, thereby improving the response speed of the battery compartment 1 to the power control of the battery 2.

[0060] The present embodiment also provides a video light, including a light body 3 and a battery compartment 1. The battery compartment 1 is the battery compartment 1 of the power supply component in any of the above embodiments. The battery compartment 1 is electrically connected to the light body 3. The battery compartment 1 is used to install a battery 2 for powering the light body 3. The battery compartment 1 has a power controller (not shown in the figure) and a first sensor 12 electrically connected to the power controller. The first sensor 12 is used to sense the second sensor 22 on the battery 2 so that the power controller adjusts the output power of the battery 2.

[0061] Since the battery compartment 1 can determine the type of battery 2, the output power control of the battery 2 can be adjusted. For example, for a battery 2 with a rated power higher than that of the lamp body 3, the output power of the battery 2 can be limited to prevent the battery 2 from outputting too high a power and causing excessive current in the video light and burning out the lamp body 3. For a battery 2 with a rated power lower than that of the lamp body 3, the output power of the battery 2 can also be limited to prevent the battery 2 from outputting too high a power and causing severe heat generation and damage. Therefore, the video light has a long service life.

[0062] In some embodiments, the video light may further include the battery 2 of the above-mentioned power supply component, that is, the battery 2 containing the second sensor 22 is used in conjunction with the battery compartment 1; in other embodiments, the video light may not include the battery 2 of the above-mentioned power supply component, that is, an ordinary battery is used and installed in the battery compartment 1.

[0063] Reference Figure 1 and Fig. 9 A light guide plate 31 is also provided on the lamp body 3, and the light guide plate 31 can guide the light emitted by the lamp body 3, so that the light emitted by the lamp body 3 is more concentrated.

[0064] The above are only preferred embodiments of the present application and are not intended to limit the present application. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present application should be included in the protection scope of the present application.
