Technical Field

[0001] This application relates to the field of supplementary lighting technology, and in particular to a brightness adjustment device and its control method. Background Technology

[0002] The number of amateur photographers is increasing, and they enjoy shooting small objects at close range. To ensure image quality, when shooting at night or in low-light conditions, they need to use additional lighting devices for supplemental illumination. Small lighting devices have insufficient brightness to meet the requirements for high-quality photos. Large lighting devices are inconvenient to carry outdoors. Therefore, current lighting devices are not well adapted to these shooting needs. Summary of the Invention

[0003] The main purpose of this application is to propose a brightness adjustment device and its control method, which aims to solve the technical problem that current brightness adjustment devices cannot well adapt to shooting needs.

[0004] To achieve the above objectives, this application proposes a brightness adjustment device, comprising:

[0005] 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, which are spaced apart and dispersed to emit a large-area and continuously stable light source. The second light-emitting body includes a plurality of second light-emitting elements, which are concentrated to make the light-emitting area of ​​the second light-emitting body smaller than that of the first light-emitting body. The light intensity of the second light-emitting elements is greater than that of the first light-emitting elements, so that the light brightness of the second light-emitting body is greater than that of the first light-emitting body.

[0006] 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.

[0007] In some embodiments, the control mechanism includes at least a first adjustment position, a second adjustment position, and a third adjustment position. When the control mechanism is in the first adjustment position, the first control circuit is connected and the second control circuit is not connected. When the control mechanism is in the second adjustment position, the first control circuit is not connected and the second control circuit is connected. When the control mechanism is in the third adjustment position, both the first control circuit and the second control circuit are connected.

[0008] In some embodiments, the second control circuit is provided with a boost element, which is used to convert low voltage current into high voltage current so that the second light emitter can produce a flash.

[0009] In some embodiments, the control mechanism includes an adjustment knob having 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 when pressed. In the first adjustment state, the adjustment knob is connected to the first control circuit so that the adjustment knob controls the adjustment of 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 adjustment of the current flowing through the second control circuit.

[0010] In some embodiments, the first light-emitting body has a ring structure, and a plurality of the first light-emitting elements are spaced apart and dispersed along the circumference of the first light-emitting body.

[0011] In some embodiments, the control mechanism is provided with a connecting groove, and the light-emitting mechanism is housed within the connecting groove.

[0012] In some embodiments, the groove wall of the connecting groove is provided with a first snap-fit ​​member, and the light-emitting mechanism is provided with a second snap-fit ​​member. The second snap-fit ​​member and the first snap-fit ​​member cooperate to make the light-emitting mechanism snap into the connecting groove.

[0013] In some embodiments, the groove wall of the connecting groove is provided with a first magnetic attractor, and the light-emitting mechanism is provided with a second magnetic attractor. The second magnetic attractor and the first magnetic attractor cooperate to magnetically connect the light-emitting mechanism to the connecting groove.

[0014] In some embodiments, the groove wall of the connecting groove is provided with a rotating shaft, and the light-emitting mechanism is provided with a connecting hole, wherein the rotating shaft can be inserted into the connecting hole to realize the rotational connection of the light-emitting mechanism.

[0015] Correspondingly, this application also proposes a control method for a brightness adjustment device, including:

[0016] By controlling the first control circuit to be connected and the second control circuit to be disconnected, 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;

[0017] By controlling the first control circuit to be disconnected and the second control circuit to be connected, 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.

[0018] The first control circuit and the second control circuit are both connected so that the first light-emitting body and the second light-emitting body emit light sources, thereby realizing the light-emitting mechanism's wide-range and high-brightness light emission.

[0019] Compared with the prior art, the beneficial effects of this application are:

[0020] In the technical solution of this application, when a large-area light source is needed from the brightness adjustment device, the first control circuit is connected while the second control circuit is disconnected, causing the first light-emitting body to turn on and the second light-emitting body to turn off. This allows the light-emitting mechanism to emit a large-area and continuously stable light source, which can be used to provide appropriate supplementary lighting for shooting in dark environments. When a brighter light source is needed from the brightness adjustment device, the first control circuit is disconnected while the second control circuit is connected, causing the first light-emitting body to turn off and the second light-emitting body to turn on. This allows the light-emitting mechanism to emit a relatively bright light source, which can be used to provide strong supplementary lighting for shooting in very dark environments, ensuring the quality of the final image. When a large-area and high-brightness light source is needed from the brightness adjustment device, both the first and second control circuits are connected, causing both the first and second light-emitting bodies to turn on. This allows the light-emitting mechanism to emit a large-area and high-brightness light source, which can be used to provide strong supplementary lighting for shooting in very dark environments with a large shooting range.

[0021] By arranging several primary light-emitting elements at intervals and in a dispersed manner, a large luminous area and a uniform, soft, and stable lighting effect are achieved. This light source is suitable for scenes requiring large-area supplemental lighting, creating ambient light, and reducing harsh shadows, effectively meeting the demand for a uniform, wide, and stable light source. By concentrating several secondary light-emitting elements and making their light intensity greater than that of the primary light-emitting elements, a focused light effect with a relatively smaller luminous area but higher brightness (light intensity) is achieved. This light source is suitable for scenes requiring focused local lighting and creating strong light and shadow contrasts, effectively meeting the demand for high-brightness and highly directional light sources. Through the coordinated operation of the primary and secondary light sources, corresponding supplemental lighting can be provided for different application scenarios, improving the adaptability of the brightness adjustment device to different application scenarios and lighting requirements, ensuring that users can cope with complex and ever-changing shooting requirements without frequently changing equipment.

[0022] By controlling the light emission of the first and second light-emitting elements separately, the brightness adjustment device can be adapted to different shooting environments, improving its versatility and ensuring shooting quality. Attached Figure Description

[0034] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0035] It should be noted that if the embodiments of this application involve directional indicators (such as up, down, left, right, front, back, etc.), the directional indicators are only used to explain the relative positional relationship and movement of the components in a specific posture. If the specific posture changes, the directional indicators will also change accordingly.

[0036] Furthermore, if the embodiments of this application involve descriptions such as "first" or "second," these descriptions are for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined with "first" or "second" may explicitly or implicitly include at least one of those features. Additionally, the use of "and / or," "and / or," or "and / or" throughout the text implies three parallel solutions. For example, "A and / or B" includes solution A, solution B, or a solution where A and B are simultaneously satisfied. Furthermore, the technical solutions of the various embodiments can be combined with each other, but this must be based on the ability of those skilled in the art to implement them. When the combination of technical solutions is contradictory or impossible to implement, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection claimed in this application.

[0037] The number of amateur photographers is increasing, and they enjoy shooting small objects at close range. To ensure image quality, when shooting at night or in low-light conditions, they need to use additional lighting devices for supplemental illumination. Small lighting devices have insufficient brightness to meet the requirements for high-quality photos. Large lighting devices are inconvenient to carry outdoors. Therefore, current lighting devices are not well adapted to these shooting needs.

[0038] Based on this, in order to solve the technical problem that current brightness adjustment devices cannot well adapt to shooting needs, referring to Figures 1 to 3 One embodiment of this 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, through which the brightness adjustment device 10 and the photographic device can be connected. 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, which are spaced apart and dispersed to emit a large area of ​​light that is continuously and stably emitted. The second light-emitting body 120 includes a plurality of second light-emitting elements, which are concentrated to make the light-emitting area of ​​the second light-emitting body 120 smaller than that of the first light-emitting body 110, and the light intensity of the second light-emitting elements is greater than that of the first light-emitting elements, so that the light brightness of the second light-emitting body 120 is greater than that 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 element 110 and is used to control the opening and closing of the first light-emitting element 110. The second control circuit is electrically connected to the second light-emitting element 120 and is used to control the opening and closing of the second light-emitting element 120.

[0039] It should be noted that in the above scheme, the terms "dispersed," "larger area," and "continuously stable" in "a plurality of first light-emitting elements are spaced apart and dispersed so that the first light-emitting body 110 emits a light source with a large area and continuous stability" are relative to the second light-emitting elements. Similarly, the term "concentrated" in "a plurality of second light-emitting elements are concentrated" is relative to the first light-emitting elements.

[0040] Specifically, in this embodiment, when the brightness adjustment device 10 needs to emit a large area of ​​light, the first control circuit is connected and the second control circuit is disconnected, causing the first light emitter 110 to turn on and the second light emitter 120 to turn off, so that the light-emitting mechanism 100 emits a large area of ​​continuous and stable light. This can be used to shoot scenes in dark environments to provide appropriate supplementary lighting for shooting. When the brightness adjustment device 10 needs to emit a brighter light, the first control circuit is disconnected and the second control circuit is connected, causing the first light emitter 110 to turn off and the second light emitter 120 to turn on, so that the light-emitting mechanism 100 emits a relatively bright light. This can be used to shoot scenes in very dark environments to provide strong supplementary lighting for shooting and ensure the quality of the final image. When the brightness adjustment device 10 needs to emit a large area of ​​high brightness light, both the first control circuit and the second control circuit are connected, causing both the first light emitter 110 and the second light emitter 120 to turn on, so that the light-emitting mechanism 100 emits a large area of ​​high brightness light. This can be used to shoot scenes in very dark environments with a large shooting range to provide strong supplementary lighting over a large area for shooting.

[0041] By arranging several first light-emitting elements at intervals and in a dispersed manner, a large luminous area and a uniform, soft, and stable lighting effect are achieved. This light source is suitable for scenes requiring large-area supplemental lighting, creating ambient light, and reducing harsh shadows, effectively meeting the demand for a uniform, wide, and stable light source. By concentrating several second light-emitting elements and making their light intensity greater than that of the first light-emitting elements, a focused light effect with a relatively smaller luminous area but higher brightness (light intensity) is achieved. This light source is suitable for scenes requiring localized focused lighting and creating strong light and shadow contrasts, effectively meeting the demand for high-brightness and highly directional light sources. Through the coordinated operation of the first light-emitting element 110 and the second light-emitting element 120, corresponding supplemental lighting can be provided for different application scenarios, 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 ever-changing shooting requirements without frequently changing equipment.

[0042] The device of this application has a built-in self-powered power supply to provide 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.

[0043] In some embodiments, refer to Figures 1 to 3 The 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 not connected, causing the first light-emitting element 110 to turn on and the second light-emitting element 120 to turn off. At this time, the light-emitting mechanism 100 can emit a large-area and continuously stable light source. When the control mechanism 200 is in the second adjustment position 220, the first control circuit is not connected and the second control circuit is connected, causing the first light-emitting element 110 to turn off and the second light-emitting element 120 to turn on. At this time, the light-emitting mechanism 100 can emit a light source with relatively high brightness. When the control mechanism 200 is in the third adjustment position 230, both the first and second control circuits are connected, causing both the first light-emitting element 110 and the second light-emitting element 120 to turn on. At this time, the light-emitting mechanism 100 can emit a large-area and relatively high-brightness light source. The control mechanism 200 can be adjusted to the corresponding adjustment position by pressing. For example, to turn on the first light source 110 and turn off the second light source 120, press the first adjustment position 210. To turn off the first light source 110 and turn on the second light source 120, press the second adjustment position 220. To turn on both the first light source 110 and the second light source 120, press the third adjustment position 230.

[0044] Specifically, in this embodiment, by setting the first adjustment level 210, the second adjustment level 220, and the third adjustment level 230, the on / off states of the first light emitter 110 and the second light emitter 120 can be independently controlled, achieving fast, precise, and interference-free switching of light source modes. The three most commonly used and core lighting modes (soft light only, focused light only, and dual-light mixing) are correspondingly set on intuitive physical levels. Users do not need to operate or memorize complex combination buttons or navigate through layers of electronic menus, making operation more intuitive and convenient. Simply pressing the corresponding adjustment level position yields the desired lighting effect, making it suitable for use in shooting scenarios requiring rapid response.

[0045] In some embodiments, refer to Figure 3 The second control circuit is equipped with a boost element 240, which is used to convert low voltage current into high voltage current so that the second light emitter 120 can produce a flash.

[0046] Specifically, in this embodiment, by setting a boost element 240, the low voltage current (such as battery voltage) normally supplied by the device can be efficiently converted into the high voltage current required to drive the second light emitter 120. After the voltage is boosted, the second light emitter 120 can generate high-intensity, short-duration burst light, enabling the second light emitter 120 to be excited to its peak brightness in a very short time (usually in the millisecond range), emitting instantaneous high light intensity far exceeding its continuous light emission capability, effectively improving the luminous brightness of the second light emitter 120. Moreover, the second light emitter 120 adopts a flashing light emission mode, which not only reduces the overall energy consumption of the device and extends the battery life, but also alleviates the heat dissipation pressure caused by high-brightness light emission, simplifies the heat dissipation structure design, and is conducive to the miniaturization and weight reduction of the device. In addition, it can also avoid the problem of accelerated light decay of the light-emitting element that may be caused by continuous high-brightness operation, improving the service life and stability of the device.

[0047] In some embodiments, refer to Figure 2 and Figure 3 The control mechanism 200 includes an adjustment knob 250, which has a first adjustment state and a second adjustment state. The adjustment knob 250 is configured to switch between the first and second adjustment states when pressed. In the first adjustment state, the adjustment knob 250 is connected to a first control circuit so that the adjustment knob 250 controls the adjustment of the current flowing through the first control circuit. For example, rotating the adjustment knob 250 clockwise increases the current flowing through the first control circuit, thereby increasing the brightness of the first light-emitting element 110. Rotating the adjustment knob 250 counterclockwise decreases the current flowing through the first control circuit, thereby reducing the brightness of the first light-emitting element 110. In the second adjustment state, the adjustment knob 250 is connected to a second control circuit so that the adjustment knob 250 controls the adjustment of the current flowing through the second control circuit. For example, rotating the adjustment knob 250 clockwise increases the current flowing through the second control circuit, thereby increasing the brightness of the second light-emitting element 120. Furthermore, the brightness of the second light-emitting element 120 can be reduced by rotating the adjustment knob 250 in reverse to decrease the current flowing through the second control circuit.

[0048] 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 by 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, the brightness adjustment of two different light emitters (the large-area soft light of the first light emitter 110 and the high-brightness focused light of the second light emitter 120) can be controlled separately and independently by a single physical knob.

[0049] By adopting the above design, the brightness of the first light source 110 and the second light source 120 can be adjusted according to the brightness of the shooting environment, ensuring that the first light source 110 and the second light source 120 can provide sufficient brightness while saving energy consumption of the first light source 110 and the second light source 120, and avoiding the first light source 110 and the second light source 120 emitting too bright a brightness when the shooting environment is bright.

[0050] In some embodiments, refer to Figure 1 The first light-emitting body 110 has a ring-shaped structure, and several first light-emitting elements are spaced apart and dispersed along the circumference of the first light-emitting body 110. With the above design, the light emitted by the first light-emitting body 110 is circular, without producing sharp corners or dark corners, which better meets the requirements of photography. Moreover, the circular illumination area is larger, more uniform, and more cost-effective than the square illumination area.

[0051] In some embodiments, refer to Figures 1 to 3 The control mechanism 200 is provided with a connecting groove 260, and the light-emitting mechanism 100 is housed 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 be a detachable structure.

[0052] Specifically, in this embodiment, by embedding the light-emitting mechanism 100 entirely into the connecting groove 260 of the control mechanism 200, a tight nesting and high integration of the light-emitting mechanism 100 and the control mechanism 200 in physical space is achieved. This "groove accommodating" structure effectively utilizes the three-dimensional space of the control mechanism 200, reduces the overall volume of the brightness adjustment device 10, and improves the portability of the brightness adjustment device 10.

[0053] Furthermore, by embedding the light-emitting mechanism 100 entirely into the connecting groove 260 of the control mechanism 200, the connecting groove 260 can provide precise physical positioning and stable mechanical support for the light-emitting mechanism 100, preventing displacement, loosening, or shaking of the light-emitting mechanism 100 during use. This improves the overall structural rigidity and impact and vibration resistance of the brightness adjustment device 10, ensuring the stability and reliability of the internal circuit connections and optical component positions under dynamic shooting conditions, and avoiding the risk of light source pointing deviation, poor contact, or damage caused by loosening.

[0054] In some embodiments, a method is provided for detachably connecting the light-emitting mechanism 100 and the control mechanism 200. For example, the groove wall of the connecting groove 260 is provided with a first snap-fit ​​member, and the light-emitting mechanism 100 is provided with a second snap-fit ​​member. The second snap-fit ​​member and the first snap-fit ​​member cooperate to snap the light-emitting mechanism 100 into the connecting groove 260. Exemplarily, for example, the first snap-fit ​​member can be a snap-fit ​​groove, and the second snap-fit ​​member can be a snap-fit ​​protrusion. Alternatively, the first snap-fit ​​member can be a snap-fit ​​protrusion, and the second snap-fit ​​member can be a snap-fit ​​groove.

[0055] Specifically, in this embodiment, the light-emitting mechanism 100 and the control mechanism 200 are connected by a snap-fit ​​connection. Firstly, through a simple alignment and pressing action, the second snap-fit ​​member of the light-emitting mechanism 100 automatically engages and locks with the first snap-fit ​​member on the wall of the connecting groove 260, thus securing the light-emitting mechanism 100 to the control mechanism 200. During disassembly, typically only a specific release force (such as pressing a specific area or slight prying) is needed to release the snap-fit ​​engagement. Compared to traditional fasteners such as screws and bolts, the above assembly and disassembly process requires no tools, is simple and quick to operate, and significantly improves the efficiency of replacement or maintenance. Secondly, the mechanical interlocking structure formed between the first and second latching components provides a deterministic positive holding force, effectively resisting gravity, vibration, and accidental impacts. This prevents the light-emitting mechanism 100 from loosening, slipping, or falling off within the connecting groove 260 due to external forces. Even during mobile shooting, equipment carrying, or bumpy environments, it ensures that the light-emitting mechanism 100 and the control mechanism 200 maintain a precise and stable relative position, guaranteeing the stability of the optical path and the reliability of the electrical connection. Thirdly, when the latching components successfully engage, a clear "click" sound or obvious tactile feedback is usually heard, providing users or assembly personnel with an intuitive indication of successful connection and avoiding potential problems caused by incomplete connection.

[0056] In some embodiments, another method is provided for the detachable connection of the light-emitting mechanism 100 and the control mechanism 200. For example, the groove wall of the connecting groove 260 is provided with a first magnetic member, and the light-emitting mechanism 100 is provided with a second magnetic member. The second magnetic member and the first magnetic member cooperate to magnetically connect the light-emitting mechanism 100 to the connecting groove 260.

[0057] Specifically, in this embodiment, the light-emitting mechanism 100 and the control mechanism 200 are connected by magnetic attraction. Firstly, when the light-emitting mechanism 100 approaches the connecting groove 260 to a certain distance, the magnetic force between the magnetic components automatically guides and quickly attracts it into place, achieving "blind operation" installation. Secondly, this enables a non-destructive connection between the light-emitting mechanism 100 and the control mechanism 200, ensuring the structural strength of both.

[0058] In some embodiments, the groove wall of the connecting groove 260 is provided with a rotating shaft, and the light-emitting mechanism 100 is provided with a connecting hole, so that the rotating shaft can be inserted into the connecting hole to realize the rotational connection of the light-emitting mechanism 100. Alternatively, the groove wall of the connecting groove 260 is provided with a connecting hole, and the light-emitting mechanism 100 is provided with a rotating shaft.

[0059] Specifically, in this embodiment, the above-described structure facilitates the adjustment of the angle between the light-emitting mechanism 100 and the control mechanism 200, thereby facilitating the change of the illumination direction and coverage of the light-emitting mechanism 100, so that the light is accurately projected onto a specific position or area of ​​the subject, and improving the applicability of the brightness adjustment device 10.

[0060] There is a large damping between the rotating shaft and the connecting hole. After the light-emitting mechanism 100 is adjusted to the required angle, the friction between the rotating shaft and the connecting hole can ensure that the light-emitting mechanism 100 is stably maintained at the set angle. Even under slight touch, equipment movement or low-intensity vibration, the light-emitting mechanism 100 can effectively resist unexpected angle deviation and ensure the consistency of the lighting effect.

[0061] Correspondingly, another embodiment of this application also provides a control method for the brightness adjustment device 10, the control method including:

[0062] The first control circuit is connected and the second control circuit is disconnected, so that the first light-emitting body 110 emits light and the second light-emitting body 120 does not emit light, thereby realizing the large-area light emission of the light-emitting mechanism 100.

[0063] The first control circuit is de-connected, and the second control circuit is connected, so that the first light-emitting body 110 does not emit light and the second light-emitting body 120 emits light, thereby achieving high-brightness light emission of the light-emitting mechanism 100.

[0064] The first control circuit and the second control circuit are connected so that the first light-emitting body 110 and the second light-emitting body 120 emit light sources, thereby realizing the large-range and high-brightness light emission of the light-emitting mechanism 100.

[0065] Specifically, in this embodiment, by separately controlling the light emission of the first light-emitting body 110 and the second light-emitting body 120, the brightness adjustment device 10 can be made suitable for different shooting environments, thereby improving the versatility of the brightness adjustment device 10 and ensuring shooting quality.

[0066] Thanks to the improvements to the brightness adjustment device 10 described above, the control method of this embodiment has the same technical effect as the brightness adjustment device 10 described above, and will not be repeated here.

[0067] It should be noted that other undisclosed aspects of the brightness adjustment device 10 and its control method provided in this application can be found in the prior art, and will not be repeated here.

[0068] The above are merely preferred embodiments of this application and do not limit the patent scope of this application. Any equivalent structural transformations made based on the content of the specification and drawings of this application under the concept of this application, or direct / indirect applications in other related technical fields, are included within the patent protection scope of this application.
