[0004] To achieve the above objectives, the present application proposes a brightness adjustment device, comprising: The light-emitting mechanism includes a first light-emitting body and a second light-emitting body, the first light-emitting body includes a plurality of first light-emitting elements, the plurality of first light-emitting elements are spaced and dispersed so that the first light-emitting body emits a large area of ​​continuous and stable light; the second light-emitting body includes a plurality of second light-emitting elements, the plurality of second light-emitting elements are concentrated so that the light-emitting area of ​​the second light-emitting body is smaller than the light-emitting area of ​​the first light-emitting body, and the light intensity of the second light-emitting elements is greater than the light intensity of the first light-emitting elements, so that the light brightness of the second light-emitting body is greater than the light brightness of the first light-emitting body; The control mechanism includes a first control circuit and a second control circuit, the first control circuit is electrically connected to the first light-emitting body, and is used to control the opening and closing of the first light-emitting body; the second control circuit is electrically connected to the second light-emitting body, and is used to control the opening and closing of the second light-emitting body.

[0005] In some embodiments, the control mechanism includes at least a first adjustment gear, a second adjustment gear and a third adjustment gear. When the control mechanism is in the first adjustment gear, the first control circuit is connected and the second control circuit is not connected. When the control mechanism is in the second adjustment gear, the first control circuit is not connected and the second control circuit is connected. When the control mechanism is in the third adjustment gear, both the first control circuit and the second control circuit are connected.

[0006] In some embodiments, the second control circuit is provided with a boost element, and the boost element is used to convert a low voltage current into a high voltage current so that the second light-emitting body can produce a flash.

[0007] In some embodiments, the control mechanism includes an adjustment knob, which has a first adjustment state and a second adjustment state. The adjustment knob is configured to switch between the first adjustment state and the second adjustment state after being pressed. In the first adjustment state, the adjustment knob is connected to the first control circuit so that the adjustment knob controls the current flowing through the first control circuit. In the second adjustment state, the adjustment knob is connected to the second control circuit so that the adjustment knob controls the current flowing through the second control circuit.

[0008] In some embodiments, the first light-emitting body is in a ring structure, and a plurality of the first light-emitting elements are spaced and dispersed along the circumference of the first light-emitting body.

[0009] In some embodiments, the control mechanism is provided with a connecting groove, and the light-emitting mechanism is accommodated in the connecting groove.

[0010] In some embodiments, a first clamping member is provided on the groove wall of the connecting groove, and a second clamping member is provided on the light emitting mechanism. The second clamping member cooperates with the first clamping member to enable the light emitting mechanism to be clamped to the connecting groove.

[0011] In some embodiments, the groove wall of the connecting groove is provided with a first magnetic component, and the light-emitting mechanism is provided with a second magnetic component.

[0012] In some embodiments, a groove wall of the connecting groove is provided with a rotating shaft, and the light-emitting mechanism is provided with a connecting hole, and the rotating shaft can be inserted into the connecting hole to achieve rotational connection of the light-emitting mechanism.

[0013] Correspondingly, the present application also proposes a control method for a brightness adjustment device, comprising: Controlling the first control circuit to be connected and controlling the second control circuit to be disconnected, so that the first light-emitting body emits light and the second light-emitting body does not emit light, thereby achieving wide-range light emission of the light-emitting mechanism; Controlling the first control circuit to be disconnected and controlling the second control circuit to be connected so that the first light-emitting body does not emit light and the second light-emitting body emits light, thereby achieving high-brightness light emission of the light-emitting mechanism; The first control circuit and the second control circuit are controlled to be connected, so that the first light-emitting body and the second light-emitting body both emit light, thereby realizing a wide range and high brightness light emission of the light-emitting mechanism.

[0014] Compared with the prior art, the present invention has the following advantages: In the technical solution of the present application, when the brightness adjustment device is required to emit a large area of ​​light, the first control circuit is controlled to be connected and the second control circuit is controlled to be disconnected, so that the first light-emitting body is turned on and the second light-emitting body is turned off, so that the light-emitting mechanism emits a large area of ​​continuous and stable light. In this case, it can be used to shoot scenes with a darker environment and provide appropriate fill light for shooting. When the brightness adjustment device is required to emit a brighter light, the first control circuit is controlled to be disconnected and the second control circuit is controlled to be connected, so that the first light-emitting body is turned off and the second light-emitting body is turned on, so that the light-emitting mechanism emits a higher brightness light. In this case, it can be used to shoot scenes with a very dark environment and provide strong fill light for shooting to ensure the quality of the film. When the brightness adjustment device is required to emit a large area of ​​high brightness light, the first control circuit and the second control circuit are controlled to be connected, so that the first light-emitting body and the second light-emitting body are turned on, so that the light-emitting mechanism emits a large area of ​​high brightness light. In this case, it can be used to shoot scenes with a very dark environment and a large shooting range and provide strong fill light for shooting a large range.

[0015] By spacing and dispersing several first light-emitting elements, a large luminous area is created with uniform, soft, and stable lighting. This light source is suitable for scenarios requiring large-area fill lighting, creating ambient light, and reducing harsh shadows, effectively meeting the need for a uniform, wide, and stable light source. By centrally arranging several second light-emitting elements and increasing their intensity to be greater than that of the first light-emitting elements, a concentrated light effect is created with a relatively small luminous area but higher brightness (intensity). This light source is suitable for scenes requiring localized highlighting and creating strong light-shadow contrast, effectively meeting the need for a high-brightness, highly directional light source. The dual light sources of the first and second light-emitting elements work together to provide fill lighting for different application scenarios, improving the brightness adjustment device's adaptability to different application scenarios and lighting requirements, ensuring that users can cope with complex and changing shooting requirements without frequent equipment changes.

[0016] By individually controlling the light emission of the first light-emitting body and the second light-emitting body, it is possible to ensure that the brightness adjustment device is suitable for different shooting environments, improve the versatility of the brightness adjustment device, and ensure the shooting quality.

Obviously, the embodiments described are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

In addition, the technical solutions between the various embodiments can be combined with each other, but it must be based on the ability of ordinary technicians in this field to implement. When the combination of technical solutions is mutually contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by this application.

[0024] A growing number of amateur photographers enjoy capturing small, close-up shots of small objects. To ensure quality, supplemental lighting is often required at night or in low-light conditions. Small brightness adjustment devices offer limited brightness and are insufficient for capturing high-quality photos. Large devices are inconvenient to carry outdoors for photography. Consequently, existing brightness adjustment devices are not well suited to photography needs.

[0025] Based on this, in order to solve the technical problem that the current brightness adjustment device cannot adapt well to the shooting needs, refer to Figures 1 to 3 One embodiment of the present application provides a brightness adjustment device 10, which can be directly installed on a photographic device. For example, the brightness adjustment device 10 may include a hot shoe, and the hot shoe can be used to connect the brightness adjustment device 10 to the photographic device. The brightness adjustment device 10 also includes a light-emitting mechanism 100 and a control mechanism 200. The light-emitting mechanism 100 includes a first light-emitting body 110 and a second light-emitting body 120. The first light-emitting body 110 includes a plurality of first light-emitting elements, and the plurality of first light-emitting elements are spaced and dispersed so that the first light-emitting body 110 emits a large area of ​​continuous and stable light source; the second light-emitting body 120 includes a plurality of second light-emitting elements, and the plurality of second light-emitting elements are concentrated so that the light-emitting area of ​​the second light-emitting body 120 is smaller than the light-emitting area of ​​the first light-emitting body 110, and the light intensity of the second light-emitting element is greater than the light intensity of the first light-emitting element, so that the light-emitting brightness of the second light-emitting body 120 is greater than the light-emitting brightness of the first light-emitting body 110. The control mechanism 200 includes a first control circuit and a second control circuit. The first control circuit is electrically connected to the first light-emitting body 110 for controlling the opening and closing of the first light-emitting body 110; the second control circuit is electrically connected to the second light-emitting body 120 for controlling the opening and closing of the second light-emitting body 120.

[0026] It should be noted that in the above solution, the terms "dispersed," "larger area," and "continuously and stably" in "the plurality of first light-emitting elements are spaced and dispersed so that the first light-emitting body 110 emits a relatively large, continuous, and stable light source" refer to the second light-emitting elements. Similarly, the term "concentrated" in "the plurality of second light-emitting elements are concentrated" refers to the first light-emitting elements.

[0027] Specifically, in this embodiment, when the brightness adjustment device 10 is required to emit a large area of ​​light, the first control circuit is controlled to be connected and the second control circuit is controlled to be disconnected, so that the first light-emitting element 110 is turned on and the second light-emitting element 120 is turned off, so that the light-emitting mechanism 100 emits a large area of ​​continuous and stable light. In this case, it can be used to shoot scenes in a dark environment and provide appropriate fill light for shooting. When the brightness adjustment device 10 is required to emit a brighter light, the first control circuit is controlled to be disconnected and the second control circuit is controlled to be connected, so that the first light-emitting element 110 is turned off and the second light-emitting element 120 is turned on, so that the light-emitting mechanism 100 emits a higher brightness light. In this case, it can be used to shoot scenes in a very dark environment and provide strong fill light for shooting to ensure the quality of the film. When the brightness adjustment device 10 is required to emit a large area of ​​high brightness light, both the first control circuit and the second control circuit are controlled to be connected, so that both the first light-emitting element 110 and the second light-emitting element 120 are turned on, so that the light-emitting mechanism 100 emits a large area of ​​high brightness light. In this case, it can be used to shoot scenes in a very dark environment and a large shooting range and provide strong fill light for shooting a large range.

[0028] By spacing and dispersing a number of first light-emitting elements, a lighting effect with a large luminous area and uniform, soft, and stable light is created. This light source is suitable for scenes that require large-area fill light, create ambient light, and reduce harsh shadows, effectively meeting the demand for a uniform, wide, and stable light source. By centrally arranging a number of second light-emitting elements and making their light intensity greater than that of the first light-emitting elements, a focusing effect with a relatively small luminous area but higher brightness (light intensity) is created. This light source is suitable for scenes that require local highlighting and creating strong light and shadow contrast, effectively meeting the demand for high-brightness, highly directional light sources. Through the coordinated cooperation of the dual light sources of the first light-emitting body 110 and the second light-emitting body 120, corresponding fill light can be provided for different application scenarios, thereby improving the adaptability of the brightness adjustment device 10 to different application scenarios and different lighting requirements, ensuring that users can cope with complex and changing shooting requirements without frequently changing equipment.

[0029] The device of the present application has a built-in self-sufficient power supply for providing power to the light-emitting mechanism 100, and is also provided with an external TYPE-C input and charging interface, which can directly charge the built-in power supply.

[0030] In some embodiments, reference Figures 1 to 3The control mechanism 200 includes at least a first adjustment position 210, a second adjustment position 220, and a third adjustment position 230. When the control mechanism 200 is in the first adjustment position 210, the first control circuit is connected and the second control circuit is disconnected, so that the first light-emitting element 110 is turned on and the second light-emitting element 120 is turned off. In this case, the light-emitting mechanism 100 can emit a large area of ​​continuous and stable light. When the control mechanism 200 is in the second adjustment position 220, the first control circuit is disconnected and the second control circuit is connected, so that the first light-emitting element 110 is turned off and the second light-emitting element 120 is turned on. In this case, the light-emitting mechanism 100 can emit a light with a higher brightness. When the control mechanism 200 is in the third adjustment position 230, both the first control circuit and the second control circuit are connected, so that both the first light-emitting element 110 and the second light-emitting element 120 are turned on. In this case, the light-emitting mechanism 100 can emit a light with a larger area and higher brightness. By pressing the control mechanism 200, the corresponding adjustment position can be adjusted. For example, when the first light emitting element 110 needs to be turned on and the second light emitting element 120 needs to be turned off, the first adjustment gear 210 can be pressed. When the first light emitting element 110 needs to be turned off and the second light emitting element 120 needs to be turned on, the second adjustment gear 220 can be pressed. When both the first light emitting element 110 and the second light emitting element 120 need to be turned on, the third adjustment gear 230 can be pressed.

[0031] Specifically, in this embodiment, by setting the first adjustment position 210, the second adjustment position 220, and the third adjustment position 230, the on / off states of the first light-emitting element 110 and the second light-emitting element 120 can be independently controlled, achieving fast, precise, and cascading interference-free switching of light source modes. The three most commonly used and core lighting modes (soft light only, spotlight only, and dual-light mixed) are correspondingly set to intuitive physical positions. Users do not need to operate and memorize complex button combinations or enter layers of electronic menus to select, making user operation more intuitive and simple. Pressing the corresponding adjustment position can achieve the desired lighting effect, making it suitable for use in shooting scenarios that require fast response.

[0032] In some embodiments, reference Figure 3 The second control circuit is provided with a boost element 240, which is used to convert the low voltage current into a high voltage current so that the second light-emitting body 120 can produce a flash.

[0033] Specifically, in this embodiment, the provision of a boost element 240 efficiently converts the low-voltage current (e.g., battery voltage) normally supplied by the device into the high-voltage current required to drive the second light-emitting element 120. After the voltage is boosted, the second light-emitting element 120 is able to produce high-intensity, short-duration bursts of light. This allows the second light-emitting element 120 to be excited to peak brightness within a very short period of time (typically within milliseconds), emitting instantaneous high light intensity far exceeding its sustained luminous capacity, effectively increasing the luminous brightness of the second light-emitting element 120. Furthermore, the second light-emitting element 120 employs a flashing light emission mode, which not only reduces the overall energy consumption of the device and extends battery life, but also alleviates the heat dissipation pressure associated with high-brightness emission, simplifies the heat dissipation structure design, and facilitates device miniaturization and lightweighting. Furthermore, it avoids the accelerated light decay of the light-emitting element that can result from continuous high-brightness operation, thereby extending the device's service life and stability.

[0034] In some embodiments, reference Figure 2 and Figure 3 The control mechanism 200 includes an adjustment knob 250 having a first adjustment state and a second adjustment state. The adjustment knob 250 is configured to switch between the first adjustment state and the second adjustment state upon being pressed. In the first adjustment state, the adjustment knob 250 is connected to the first control circuit, so that the adjustment knob 250 controls and adjusts the current flowing through the first control circuit. For example, by turning the adjustment knob 250 forward, the current flowing through the first control circuit can be increased, thereby increasing the brightness of the first light-emitting element 110. Furthermore, by turning the adjustment knob 250 backward, the current flowing through the first control circuit can be decreased, thereby decreasing the brightness of the first light-emitting element 110. In the second adjustment state, the adjustment knob 250 is connected to the second control circuit, so that the adjustment knob 250 controls and adjusts the current flowing through the second control circuit. For example, by turning the adjustment knob 250 forward, the current flowing through the second control circuit can be increased, thereby increasing the brightness of the second light-emitting element 120. Furthermore, the current flowing through the second control circuit can be reduced by reversely rotating the adjustment knob 250, thereby reducing the brightness of the second light-emitting body 120.

[0035] Specifically, in this embodiment, by configuring the adjustment knob 250 to have a first adjustment state and a second adjustment state that can be switched under pressure, and ensuring that the adjustment knob 250 is only connected to the first control circuit in the first adjustment state, and ensuring that the adjustment knob 250 is only connected to the second control circuit in the second adjustment state, it is achieved that a single physical knob can separately and independently control the brightness adjustment of two different light-emitting bodies (the large-area soft light of the first light-emitting body 110 and the high-brightness concentrated light of the second light-emitting body 120).

[0036] By adopting the above design, the brightness of the first light-emitting body 110 and the second light-emitting body 120 can be adjusted according to the brightness and darkness adaptability of the shooting environment, ensuring that the first light-emitting body 110 and the second light-emitting body 120 can provide sufficient brightness while saving the energy consumption of the first light-emitting body 110 and the second light-emitting body 120, and avoiding the first light-emitting body 110 and the second light-emitting body 120 still emitting a relatively bright brightness when the shooting environment is relatively bright.

[0037] In some embodiments, reference Figure 1 The first light-emitting element 110 is annular in structure, with a plurality of first light-emitting elements spaced and dispersed along the circumference of the first light-emitting element 110. This design creates a circular light pattern, eliminating sharp corners and dark angles, making it more suitable for photography. Furthermore, the circular pattern provides a larger, more uniform, and more cost-effective illumination area than a square pattern.

[0038] In some embodiments, reference Figures 1 to 3 The control mechanism 200 is provided with a connecting groove 260, and the light emitting mechanism 100 is accommodated in the connecting groove 260. For example, the light emitting mechanism 100 and the control mechanism 200 can be an integrally formed structure, or the light emitting mechanism 100 and the control mechanism 200 can also be a detachable structure.

[0039] Specifically, in this embodiment, by embedding the entirety of the light-emitting mechanism 100 within the connecting groove 260 of the control mechanism 200, the light-emitting mechanism 100 and the control mechanism 200 are tightly nested and highly integrated in physical space. This "groove-containing" structure effectively utilizes the three-dimensional space of the control mechanism 200, reduces the overall volume of the brightness adjustment device 10, and improves its portability.

[0040] Moreover, by embedding the light-emitting mechanism 100 as a whole into the connecting groove 260 of the control mechanism 200, it can be ensured that the connecting groove 260 provides precise physical positioning and stable mechanical support for the light-emitting mechanism 100, preventing the light-emitting mechanism 100 from shifting, loosening or shaking during use, thereby improving the overall structural rigidity and impact and vibration resistance of the brightness adjustment device 10, ensuring the stability and reliability of the internal circuit connection and optical component position in a dynamic shooting environment, and avoiding the risk of light source direction deviation, poor contact or damage due to looseness.

[0041] In some embodiments, a method for achieving a detachable connection between the light-emitting mechanism 100 and the control mechanism 200 is provided. For example, a first latching member is provided on the wall of the connecting groove 260, and a second latching member is provided on the light-emitting mechanism 100. The second latching member cooperates with the first latching member to latch the light-emitting mechanism 100 into the connecting groove 260. For example, the first latching member can be a latching groove, and the second latching member can be a latching protrusion. Alternatively, the first latching member can be a latching protrusion, and the second latching member can be a latching groove.

[0042] Specifically, in this embodiment, the light-emitting mechanism 100 and the control mechanism 200 utilize a snap-fit ​​connection. First, with a simple press-fit action, the second snap-fitting member of the light-emitting mechanism 100 automatically engages and locks with the first snap-fitting member of the wall of the connection groove 260, securely securing the light-emitting mechanism 100 to the control mechanism 200. During disassembly, the snap-fit ​​connection can typically be released by applying a specific release force (such as pressing a specific area or gently prying). Compared to traditional fasteners such as screws and bolts, this assembly and disassembly process requires no tools, making it simple and quick to operate, significantly improving the efficiency of replacement or maintenance. Secondly, the mechanical interlocking structure formed between the first and second clips can provide a deterministic positive retention force, effectively resisting gravity, vibration, and accidental impact, and preventing the light-emitting mechanism 100 from loosening, slipping, or falling off due to external forces in the connection groove 260. Even in mobile shooting, equipment carrying, or bumpy environments, it can ensure that the light-emitting mechanism 100 and the control mechanism 200 maintain a precise and stable relative position, ensuring the stability of the optical path and the reliability of the electrical connection. Thirdly, when the clips are successfully engaged, it is usually accompanied by a clear "click" sound or obvious tactile feedback, providing the user or assembler with an intuitive indication of successful connection, avoiding potential problems caused by incomplete connection.

[0043] In some embodiments, another method for achieving a detachable connection between the light-emitting mechanism 100 and the control mechanism 200 is provided. For example, the groove wall of the connecting groove 260 is provided with a first magnetic component, and the light-emitting mechanism 100 is provided with a second magnetic component. The second magnetic component and the first magnetic component cooperate to enable the light-emitting mechanism 100 to be magnetically connected to the connecting groove 260.

[0044] Specifically, in this embodiment, the light-emitting mechanism 100 and the control mechanism 200 are connected magnetically. Firstly, when the light-emitting mechanism 100 is brought within a certain distance of the connection groove 260, the magnetic force between the magnetic components automatically guides the connection and quickly snaps into place, enabling "blind installation." Secondly, this allows for a lossless connection between the light-emitting mechanism 100 and the control mechanism 200, ensuring their structural strength.

[0045] In some embodiments, the wall of the connecting groove 260 is provided with a rotation axis, and the light-emitting mechanism 100 is provided with a connection hole, and the rotation axis can be inserted into the connection hole to achieve the rotation connection of the light-emitting mechanism 100. Alternatively, the wall of the connecting groove 260 is provided with a connection hole, and the light-emitting mechanism 100 is provided with a rotation axis.

[0046] Specifically, in this embodiment, the above-mentioned structure is adopted to facilitate adjustment of the angle of the light-emitting mechanism 100 relative to the control mechanism 200, thereby facilitating change of the illumination direction and coverage range of the light-emitting mechanism 100, so that the light is accurately projected to a specific position or area of ​​the subject, thereby improving the applicability of the brightness adjustment device 10.

[0047] There is a large damping between the rotating shaft and the connecting hole. After the light-emitting mechanism 100 is adjusted to the desired angle, the friction between the rotating shaft and the connecting hole can ensure that the light-emitting mechanism 100 is firmly maintained at the set angle. Even in a slight touch, device movement or low-intensity vibration environment, the light-emitting mechanism 100 can effectively resist unexpected angle deviation and ensure the consistency of the lighting effect.
