[0042] Some embodiments of this disclosure will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description refers to the drawings, unless otherwise indicated, the same numbers in different drawings denote the same or similar elements. Various changes, modifications, and equivalents of the methods, apparatus, and / or systems described herein will become apparent upon understanding this disclosure. For example, the order of operations described herein is merely illustrative and is not limited to those orders set forth herein, but can be changed as will become apparent upon understanding this disclosure, except for operations that must be performed in a particular order. Furthermore, for clarity and brevity, descriptions of features known in the art may be omitted.

[0043] The embodiments described in the following examples of this disclosure are not representative of all embodiments consistent with this disclosure. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this disclosure as detailed in the appended claims.

[0044] In related technologies, most electronic devices with photographic functions are equipped with built-in flash units. However, in order to save internal space or manufacturing costs, the built-in flash units in electronic devices have low power and brightness, making it difficult to meet users' photographic needs.

[0045] In view of this, some embodiments of this disclosure provide a flash assembly that uses an external flash to compensate for the low power and brightness of the built-in flash in electronic devices.

[0046] Figure 1 This is a structural schematic diagram of a flash assembly and electronic device 1 in an assembled state, according to some embodiments of the present disclosure; Figure 2 This is a schematic diagram of the structure of a flash assembly and electronic device 1 according to some embodiments of the present disclosure; Figure 3 This is a schematic diagram illustrating the structure of a flash assembly according to some embodiments of this disclosure. Figures 1 to 3 As shown, the flash assembly includes a mounting part 2, a light-emitting part 3, a signal transmission module 4, and a control module. The mounting part 2 is used to mount to a compatible electronic device 1; the light-emitting part 3 is detachably connected to the mounting part 2 or the electronic device 1, and includes a first light-emitting unit 31; the signal transmission module 4 is disposed on the mounting part 2 and is used to acquire and transmit the flash signal from the electronic device 1; the control module is disposed on the mounting part 2 and / or the light-emitting part 3, and is communicatively connected to both the signal transmission module 4 and the first light-emitting unit 31, and is used to trigger the first light-emitting unit 31 to emit light based on the flash signal.

[0047] In the flash assembly of this embodiment, the mounting part 2 is detachably connected to the adapted electronic device 1, allowing the first light-emitting unit 31 of the light-emitting part 3 to function as an external flash of the electronic device 1. This avoids the problem of low power and brightness of the built-in flash 11 due to limitations in internal space or manufacturing costs of the electronic device 1. For the electronic device 1 equipped with a built-in flash 11, the shutter command coordinates the simultaneous operation of the camera module and the built-in flash 11. Therefore, this disclosure obtains the flash signal corresponding to the triggering of the built-in flash 11 of the electronic device 1 through the signal transmission module 4 located in the mounting part 2. The control module triggers the first light-emitting unit 31 to emit light based on the flash signal, so that the first light-emitting unit 31 emits light synchronously with the built-in flash 11, thereby matching the camera module of the electronic device 1. Furthermore, the light-emitting part 3 is detachably connected to the mounting part 2, allowing the light-emitting part 3 to be removed when the user does not need to use it for supplementary lighting.

[0048] The electronic device 1 involved in this disclosure is an electronic device with photographic function, such as a smartphone, tablet computer, or digital camera. This disclosure does not specifically limit it, but takes a smartphone as an example for the following description. In some embodiments, the mounting part 2 can be one of the following: a protective case for the electronic device 1, a lens cover, a lens filter device, a flash filter device, a power bank, an external handle, a multi-screen interactive accessory, a back clip, or other external accessories for the electronic device 1. This disclosure does not specifically limit it, as long as the mounting part 2 can be detachably connected to the electronic device 1.

[0049] In some embodiments, the control module includes a photosensitive element 5, and the signal transmission module 4 includes a light guide. The photosensitive element 5 is disposed on the outer wall of the light-emitting part 3. The light guide is used to acquire and transmit the built-in flash light signal of the electronic device 1. When the light-emitting part 3 is installed on the mounting part 2, the photosensitive element 5 faces at least part of the light guide. That is, the first light-emitting unit 31 is triggered by light sensing, and the light signal generated by the built-in flash 11 of the electronic device 1 is acquired by the photosensitive element 5 through the light guide and converted into an electrical signal readable by the control module. The control module controls the first light-emitting unit 31 to emit light based on the electrical signal.

[0050] In related technologies, the triggering method of the external flash of electronic device 1 is mostly wireless communication triggering. That is, the external flash needs to establish a wireless communication connection with electronic device 1 first, and then control the external flash to emit light through the adapted application, which is relatively cumbersome. However, in the embodiments of this disclosure, the first light-emitting unit 31 is physically triggered to emit light through photosensitive element 5. There is no need to establish a wireless communication connection with electronic device 1 or download an adapted application. It can be used immediately after installation, thereby improving the user experience.

[0051] In some embodiments, such as Figure 2 and Figure 3 As shown, the mounting part 2 has a first side 21 and a second side 22; the light-emitting part 3 is detachably connected to the first side 21, and when the mounting part 2 is mounted on the electronic device 1, the second side 22 faces the electronic device 1; at least a portion of the light guide is exposed on the first side 21. For example, the mounting part 2 can be a mobile phone case, and the mounting part 2 is snapped onto and attached to the back of the electronic device 1, with the first side 21 and the second side 22 of the mounting part 2 facing away from each other. The light guide provided on the mounting part 2 and at least partially exposed on the first side 21 can transmit the light signal of the built-in flash 11 to the first side 21, so that the light-emitting part 3 located on the first side 21 can obtain the light signal through the photosensitive element 5.

[0052] In some embodiments, such as Figure 3 As shown, the light-emitting part 3 has a third side surface 33; the photosensitive element 5 is located on the third side surface 33. When the light-emitting part 3 is mounted on the mounting part 2, the third side surface 33 faces the first side surface 21, and the portion of the light guide exposed on the first side surface 21 is opposite to the photosensitive element 5. That is, when the light-emitting part 3 is mounted on the mounting part 2, the third side surface 33 of the light-emitting part 3 can cover the first side surface 21 of the mounting part 2, so that the photosensitive element 5 covers the exposed portion of the light guide at the corresponding position.

[0053] In some embodiments, the light guide includes a receiving end 41 and an output end 42. Along the optical axis of the built-in flash 11 of the electronic device 1, the receiving end 41 at least partially covers the built-in flash 11, and the receiving end 41 is made of a transparent or semi-transparent light guide material. The output end 42 faces the photosensitive element 5. By covering the built-in flash 11 with the receiving end 41, the efficiency of the light guide in acquiring the light signal from the built-in flash 11 is improved. Furthermore, the use of a transparent or semi-transparent light guide material in the receiving end 41 allows it to guide light while also allowing light emitted from the built-in flash 11 to pass through. In other words, even when the first light-emitting unit 31 of the light-emitting part 3 is not used for supplementary lighting, the built-in flash 11 can still function normally and provide supplementary lighting even when the receiving end 41 of the built-in flash 11 of the electronic device 1 is blocked.

[0054] In some embodiments, the mounting part 2 is provided with a clearance hole 23; when the mounting part 2 is mounted on the electronic device 1, the clearance hole 23 is opposite to the built-in flash lamp 11, and the receiving end 41 is filled in the clearance hole 23. The structure is simple and easy to manufacture, and the receiving end 41 filled in the clearance hole 23 can protect the built-in flash lamp 11.

[0055] In some embodiments, the receiving end 41 of the light guide is filled within the relief hole 23, the output end 42 of the light guide is exposed on the first side 21 of the mounting portion 2, and the remaining portion of the light guide is embedded between the first side 21 and the second side 22 of the mounting portion 2. This reduces interference from external light passing through the light guide to the photosensitive element 5.

[0056] In some embodiments, the first light-emitting unit 31 includes at least one of a xenon lamp, a halogen lamp, a light-emitting diode, or a laser diode. The first light-emitting unit 31 emits light to perform at least one of pre-flash metering (Through The Lens, TTL), flash fill light, or constant light fill light to adapt to different usage scenarios or camera modes.

[0057] In this design, the first light-emitting unit 31 provides flash illumination by emitting light, meaning it emits a burst of intense light momentarily for a very short duration, suitable for scenes requiring high contrast or dynamic moments (such as night portraits). Alternatively, the first light-emitting unit 31 can provide continuous illumination, meaning it emits light continuously with soft and uniform light, suitable for live streaming or video shooting. In related technologies, in some electronic devices 1, when the shutter button is pressed in the rear camera 12 shooting mode, the built-in flash 11 performs pre-flash metering. The camera module of the electronic device 1 measures the reflected light from this pre-flash on the subject through the rear camera 12, instantly calculating the corresponding exposure parameters (such as aperture, shutter speed, ISO), and then the built-in flash 11 emits the main flash for shooting. Therefore, in some embodiments of this disclosure, the signal transmission module 4 acquires the pre-flash signal of the electronic device 1, which triggers the first light-emitting unit 31 to emit light for pre-flash metering.

[0058] In some embodiments, the light-emitting unit 3 further includes a second light-emitting unit 32; the second light-emitting unit 32 is communicatively connected to a control module, which triggers the second light-emitting unit 32 to emit light based on a flash signal; the second light-emitting unit 32 includes at least one of a xenon lamp, a halogen lamp, a light-emitting diode, or a laser diode; the second light-emitting unit 32 emits light to perform at least one of pre-flash metering, flash fill light, or constant-on fill light. The second light-emitting unit 32 and the first light-emitting unit 31 are disposed on the same side of the light-emitting unit 3. By providing the second light-emitting unit 32, the functions of the flash are further enriched. Those skilled in the art can configure the second light-emitting unit 32 according to actual needs, so that the luminous effect of the second light-emitting unit 32 is superior to the built-in flash 11 of the adapted electronic device 1.

[0059] Specifically, in some embodiments of this disclosure, the first light-emitting unit 31 includes a xenon lamp for flash illumination; the second light-emitting unit 32 includes a light-emitting diode for pre-flash metering and constant-on illumination. The control module also includes a microcontroller unit (MCU) and a trigger circuit. The photosensitive element 5 is electrically connected to the microcontroller. The photosensitive element 5 converts the acquired light signal from the built-in flash lamp 11 into an electrical signal and sends it to the microcontroller. The microcontroller controls the first light-emitting unit 31 and the second light-emitting unit 32 to emit light based on this electrical signal. A trigger circuit is provided between the photosensitive element 5 and the microcontroller. Figure 4 This is a circuit diagram of a trigger circuit shown according to some embodiments of the present disclosure, such as... Figure 4 As shown, the photosensitive element 5 uses a photodiode D1, which is electrically connected to the comparator U3. The photodiode D1 is used to acquire the light signal from the built-in flash 11, which is then converted into an electrical signal that can be processed by the control module by the comparator U3. Figure 5 This is a schematic diagram of the electrical signals output by the trigger circuit according to some embodiments of the present disclosure, such as... Figure 5 As shown, the electrical signals sent from the trigger circuit to the control module include a pre-flash signal corresponding to the pre-flash metering of the built-in flash 11 and a main flash signal corresponding to the main flash of the built-in flash 11. During the high-level duration of the pre-flash signal, the control module controls the second light-emitting unit 32 to emit light. When the control module receives the main flash signal, it controls the first light-emitting unit 31 to emit light. The camera module of the electronic device 1 uses the reflected light from the second light-emitting unit 32 for pre-flash metering, so that the exposure parameters calculated by the camera module can be better adapted to the imaging under the supplementary lighting of the first light-emitting unit 31.

[0060] In some embodiments, the second light-emitting unit 32 is also used for continuous illumination. The flash assembly also includes a control button, which is electrically connected to the control module. The control button is used to switch the flash's operating mode, such as the aforementioned flash mode, or the continuous illumination mode of the second light-emitting unit 32.

[0061] The control buttons are also used to control the light emission parameters of the first light emission unit 31 and / or the second light emission unit 32. The light emission parameters include at least one of brightness, color temperature, and light emission color.

[0062] It should be noted that although the above embodiments describe the present disclosure with the control module disposed on the light-emitting part 3, the present disclosure is not limited thereto. Those skilled in the art can, according to the actual situation, dispose of the control module on the mounting part 2, and the control module and the first light-emitting unit 31 can be electrically connected through contacts, or some components of the control module can be disposed on the mounting part 2 and other components can be disposed on the light-emitting part 3.

[0063] In some embodiments, the control module includes a first contact, and the signal transmission module 4 includes a wire portion; the first contact is disposed on the outer wall of the light-emitting part 3; one end of the wire portion is used to electrically connect with the electronic device 1 and acquire the flash signal, and the other end of the wire portion is exposed on the outer wall of the mounting part 2 and forms a second contact; when the light-emitting part 3 is mounted on the mounting part 2, the first contact and the second contact are electrically connected. This allows the control module to be electrically connected to the electronic device 1 through the first contact, the second contact, and the wire portion. That is, the control module communicates with the electronic device 1 via the wire portion to acquire the flash signal from the electronic device 1.

[0064] In some embodiments, the mounting portion 2 includes a first mounting position and a second mounting position; the first mounting position is used for detachable connection with the light-emitting portion 3, and the second mounting position is used for detachable connection with an external accessory of the electronic device 1. For example, the first mounting position of the mounting portion 2 is provided with a magnetic ring, so that the corresponding positions of the first mounting position on the first side 21 and the second side 22 are magnetic, so that the mounting portion 2 can be magnetically attracted to the back of the electronic device 1, and the light-emitting portion 3 can be magnetically attracted to the first side 21 of the mounting portion 2. The second mounting position is used for detachable connection with an external accessory of the electronic device 1, which can be a camera grip, microphone, bracket, or filter, and this disclosure does not specifically limit it.

[0065] In the above detailed description, reference has been made to the accompanying drawings, which illustrate specific aspects of this disclosure by way of illustration. In this regard, terms indicating direction or positional relationship, such as “center,” “longitudinal,” “lateral,” “length,” “width,” “thickness,” “upper,” “lower,” “front,” “rear,” “left,” “right,” “vertical,” “horizontal,” “top,” “bottom,” “inner,” “outer,” “clockwise,” “counterclockwise,” “axial,” “radial,” and “circumferential,” are used with reference to the orientation of the described figures. Since components of the described device can be positioned in multiple different orientations, directional terms are used for illustrative purposes and not for limitation. It should be understood that other aspects can be utilized and structural or logical changes can be made without departing from the concept of this disclosure. Therefore, the following detailed description should not be considered limiting.

[0066] It should be understood that, unless otherwise specifically indicated, features of various embodiments of this disclosure described herein can be combined with each other. As used herein, the term "and / or" includes any of the associated listed items and any combination of any two or more; it should be understood that, unless otherwise expressly specified and limited, the terms "joining," "attaching," "mounting," "connecting," "linking," "fixing," etc., used in the embodiments of this disclosure should be interpreted broadly, for example, as a fixed connection, a detachable connection, or an integral part; as a mechanical connection, an electrical connection, or a communicative connection; as a direct connection or an indirect connection through an intermediate medium; as a connection within two elements or an interaction between two elements, unless otherwise expressly limited. Those skilled in the art will understand the specific meaning of the above terms herein according to the specific circumstances.

[0067] Furthermore, the term "above" as used herein with respect to components, elements, or material layers formed or located "above" a surface may be used to indicate that the component, element, or material layer is "indirectly" positioned (e.g., placed, formed, deposited, etc.) on the surface such that one or more additional components, elements, or layers are arranged between the surface and the component, element, or material layer. However, the term "above" as used with respect to components, elements, or material layers formed or located "above" a surface may also optionally have a specific meaning: that the component, element, or material layer is "directly" positioned (e.g., placed, formed, deposited, etc.) on the surface, for example, in direct contact with the surface.

[0068] It should be understood that spatial relative terms, such as “above,” “upper,” “below,” and “lower,” are used herein to describe the relationship between one element and another shown in the figures. In addition to the orientation depicted in the figures, these spatial relative terms are also intended to encompass different orientations of the device in use or operation. For example, if the device in the figures is flipped, an element described as “above” or “upper” relative to another element would be “below” or “lower” relative to that other element. Thus, depending on the spatial orientation of the device, the term “above” encompasses both above and below orientations. Devices may have other orientations (e.g., rotated 90 degrees or in other orientations), and the spatial relative terms used herein should be interpreted accordingly.

[0069] Although terms such as “first,” “second,” and “third” may be used herein to describe various components, parts, regions, layers, or sections, these components, parts, regions, layers, or sections are not limited to these terms. Rather, these terms are used only to distinguish one component, part, region, layer, or section from another. Therefore, without departing from the teachings of the examples described herein, a first component, part, region, layer, or section mentioned in the examples may also be referred to as a second component, part, region, layer, or section. 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 indicated technical features. Thus, a feature defined as “first” or “second” may explicitly or implicitly include at least one of that feature.

[0070] It is further understood that the terms "first," "second," etc., are used to describe various types of information, but this information should not be limited to these terms. These terms are only used to distinguish information of the same type from one another, and do not indicate a specific order or degree of importance. In fact, the expressions "first," "second," etc., are completely interchangeable. For example, without departing from the scope of this disclosure, first information can also be referred to as second information, and similarly, second information can also be referred to as first information.

[0071] In this description, "multiple" means at least two, referring to two or more, such as two, three, etc., unless otherwise explicitly specified. Other quantifiers are similar. The singular forms "a," "the," and "the" are also intended to include the plural forms unless the context clearly indicates otherwise. Furthermore, unless otherwise specified or clearly indicated from the context, the articles "a" and "an" as used in this application and the appended claims are generally understood to mean "one or more."

[0072] It should be understood that, unless otherwise specifically indicated, features of various embodiments of this disclosure described herein can be combined with each other. As used herein, the term "and / or" includes any one of the related listed items and any combination of two or more; "and / or" describes the association relationship between related objects, indicating that three relationships may exist, for example, A and / or B can represent: A alone, A and B simultaneously, and B alone. The character " / " generally indicates that the preceding and following related objects are in an "or" relationship. Similarly, "at least one of..." includes any one of the related listed items and any combination of two or more.

[0073] Furthermore, the term "exemplary" is used herein to indicate that it serves as an example, instance, or illustration. Any aspect or design described herein as "exemplary" is not necessarily to be construed as advantageous compared to other aspects or designs. Rather, the use of the term "exemplary" is intended to present concepts in a concrete manner. As used herein, the term "or" is intended to indicate an inclusive "or" rather than an exclusive "or." That is, unless otherwise specified or clear from the context, "X applies A or B" is intended to indicate any of the natural inclusive permutations. That is, if X applies A; X applies B; or X applies both A and B, then applying A or B satisfies the condition under any of the foregoing instances.

[0074] Similarly, although this disclosure has been shown and described with respect to one or more implementations, equivalent variations and modifications will occur to those skilled in the art upon reading and understanding the specification and drawings. This disclosure includes all such modifications and variations and is limited only by the scope of the claims. In particular, with respect to the various functions performed by the components described above (e.g., elements, resources, etc.), unless otherwise indicated, the terminology used to describe such components is intended to correspond to any component (functionally equivalent) that performs the specific function of the described component, even if it is not structurally equivalent to the disclosed structure. Furthermore, although specific features of this disclosure may have been disclosed with respect to only one of several implementations, such features may be combined with one or more other features of other implementations, as may be desired and advantageous to any given or particular application. Moreover, with regard to the terms “comprising,” “owning,” “having,” “having,” or variations thereof as used in this disclosure, such terms are intended to be inclusive in a manner similar to the term “including.”

[0075] Other embodiments of this disclosure will readily occur to those skilled in the art upon consideration of the specification and practice of the invention disclosed herein. This application is intended to cover any variations, uses, or adaptations of this disclosure that follow the general principles of this disclosure and include common knowledge or customary techniques in the art not disclosed herein.

[0076] It should be understood that this disclosure is not limited to the precise structures described above and shown in the accompanying drawings, and various modifications and changes can be made without departing from its scope. The scope of this disclosure is limited only by the appended claims.
