[0028] Preferred embodiments of the present invention will now be described in more detail with reference to the accompanying drawings. While preferred embodiments of the present invention are shown in the drawings, it should be understood that the present invention may be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that the present invention will be thorough and complete, and will fully convey the scope of the present invention to those skilled in the art.

[0029] A fill light is a light source device used to enhance or improve light quality, widely used in photography, video shooting, live streaming, plant lighting, security monitoring, and other scenarios. Traditional photographic fill lights often employ a large lamp body and external power supply design, such as news lights or studio flashes. Their bulky size and reliance on a fixed power source make them unsuitable for outdoor mobile use or in confined spaces. Even with some portable fill lights attempting to reduce size, such as stick fill lights, the trade-off between heat dissipation and brightness remains. Traditional stick fill lights suffer from poor heat dissipation, resulting in limited brightness and short lifespan, severely impacting the user experience.

[0030] Based on this, this application provides a handheld fill light. Example

[0031] like Figures 1-5 As shown, this embodiment provides a handheld fill light, comprising:

[0032] The housing includes a bottom shell 2 and a face mask 1, the face mask 1 being snapped onto the bottom shell 2, and a receiving cavity being formed between the bottom shell 2 and the face mask 1;

[0033] The cavity contains a circuit board 5, an energy storage power supply 7, and a light-emitting element 6. The energy storage power supply 7 and the light-emitting element 6 are both electrically connected to the circuit board 5.

[0034] The mask 1 is provided with a light-transmitting plate 11, and the light-emitting element 6 is provided on one side of the light-transmitting plate 11.

[0035] Specifically, the base shell 2 of the supplementary light has four elastic locking blocks evenly distributed along its edge, each block having a wedge-shaped structure. The face mask 1, like the base shell 2, is made of ABS engineering plastic and is adapted to the shape and size of the base shell 2. The edge of the face mask 1 has four locking slots 21 corresponding to the positions of the locking blocks on the base shell 2. The shape and size of the locking slots 21 match the locking blocks. During assembly, the locking slots 21 of the face mask 1 are aligned with the locking blocks of the base shell 2, and a certain force is applied to make the locking blocks engage with the locking slots 21, thus achieving the engagement of the face mask 1 and the base shell 2. At this point, a sealed receiving cavity is formed between the base shell 2 and the face mask 1.

[0036] The light-emitting element 6 of this application uses LED beads. Multiple LED beads are arranged in a matrix on the side of the circuit board 5 facing the light-transmitting plate 11. Each LED bead has a power of 0.5W and can emit white light, yellow light or other colors. The color temperature can be adjusted between 3000K and 6500K. The LED beads are electrically connected to the circuit board 5 by soldering.

[0037] The light-transmitting plate 11 is made of high-transmittance acrylic sheet with a thickness of 0.3cm. Its size is adapted to the opening of the mask 1. The light-transmitting plate 11 is glued to the opening of the mask 1. The light-emitting element 6 is set on one side of the light-transmitting plate 11, so that the light emitted by the light-emitting element 6 can be emitted through the light-transmitting plate 11. The bottom shell 2 of the supplementary light is also provided with control buttons and a charging interface. The control buttons include a power button, a brightness adjustment button, and a color temperature adjustment button, all of which are electrically connected to the circuit board 5 and are used to control the opening and closing of the supplementary light and adjust the brightness and color temperature. The charging interface is a Type-C interface, which is electrically connected to the circuit board 5 and is used to charge the energy storage power supply 7.

[0038] The aforementioned handheld fill light integrates a circuit board 5, a power storage unit 7, and a light-emitting element 6 within a cavity formed by a base shell 2 and a face mask 1. This results in a compact and small-sized design, making it easy to carry. Furthermore, the base shell 2 and face mask 1 are connected via a snap-fit ​​mechanism, facilitating easy installation and disassembly, and aiding in future maintenance and repair. Equipped with a power storage unit 7, the fill light is free from the constraints of external power cords, allowing it to operate without a power source. This makes it widely applicable in various settings such as outdoor photography, live streaming, and emergency lighting, meeting the fill light needs of different scenarios. Moreover, the light-emitting element 6 can be controlled via the circuit board 5, further expanding the application range of this fill light.

[0039] Specifically, the heat sink 8 includes a heating end 82 and a cooling end 81. The cooling end 81 is disposed on one side of the circuit board 5, and the heating end 82 is exposed outside the bottom shell 2.

[0040] Furthermore, the heat dissipation component includes a thermoelectric cooler and a voltage regulator. The voltage regulator is disposed in the bottom shell 2. The thermoelectric cooler is electrically connected to the energy storage power supply 7. The voltage regulator is connected between the thermoelectric cooler and the energy storage power supply 7.

[0041] The semiconductor cooling chip and the voltage regulator are both electrically connected to the circuit board 5.

[0042] In this embodiment, the heat sink 8 uses a thermoelectric cooler. Its cooling end 81 directly acts on the circuit board 5, quickly absorbing the heat generated by the circuit board 5 and the light-emitting element 6. The heating end 82 is exposed outside the bottom shell 2 and can directly contact the outside air. Combined with the heat dissipation bumps on the surface, it accelerates heat dissipation, effectively improving the heat dissipation efficiency compared to traditional passive heat dissipation. The voltage regulator uses a DC-DC adjustable voltage regulator chip, which is fixed to the inner wall of the bottom shell 2 with screws, located between the energy storage power supply 7 and the thermoelectric cooler. The thermoelectric cooler is electrically connected to the energy storage power supply 7, and the voltage regulator is connected in series between the thermoelectric cooler and the energy storage power supply 7. Both the thermoelectric cooler and the voltage regulator are electrically connected to the circuit board 5 through wires. The circuit board 5 can control the working state and cooling power of the thermoelectric cooler through the voltage regulator. The voltage regulator can stabilize the working voltage of the thermoelectric cooler, avoid the impact of voltage fluctuations on heat dissipation performance, effectively control the temperature when the supplementary light operates at high power for a long time, and significantly extend its service life.

[0043] Even better, by combining the circuit board 5 with the voltage regulator, the cooling power of the semiconductor cooling chip can be flexibly adjusted according to the working power and temperature of the supplementary light, thereby reducing energy consumption and improving the battery life of the energy storage power supply 7 while ensuring heat dissipation.

[0044] Furthermore, the bottom shell 2 is also provided with a first mounting hole 23, and the face mask 1 is also provided with a second mounting hole, the second mounting hole corresponding to the first mounting hole 23;

[0045] The face mask 1 and the bottom shell 2 are locked together by a connector that connects the second mounting hole and the first mounting hole 23.

[0046] In a preferred embodiment, the mask 1 and the base shell 2 are further locked together by the cooperation of the first mounting hole 23, the second mounting hole and the connector, making the connection between the two more secure. Even when the fill light is hit or vibrated, the mask 1 and the base shell 2 can be effectively prevented from separating, ensuring the safety of the internal components.

[0047] The connector may be a screw.

[0048] Furthermore, the bottom shell 2 is also provided with a first adjustment knob 3 and a second adjustment knob 4, both of which are electrically connected to the circuit board 5.

[0049] Specifically, the first adjustment knob 3 and the second adjustment knob 4 are used to adjust the noise level and color temperature of the light-emitting element 6, respectively. In practical applications, the first adjustment knob 3 is used to adjust the noise level of the light-emitting element 6, which is achieved through the filter control module on the circuit board 5. Specifically, the driving circuit of the light-emitting element 6 integrates an RC filter unit. When the first adjustment knob 3 is rotated, the pulse signal generated by the encoder is transmitted to the STM32 control chip. The chip controls the ripple coefficient of the light-emitting current by changing the resistance value of the variable resistor in the filter unit (adjustment range 1kΩ-100kΩ): when the knob is rotated clockwise, the ripple coefficient decreases from 5% to 0.1%, reducing high-frequency stray light in the light and lowering the noise level; when rotated counterclockwise, the ripple coefficient increases, which can simulate the noise effect of natural light in specific scenarios. The second adjustment knob 4 is used to adjust the color temperature of the light-emitting element 6, and it is electrically connected to the color temperature mixing module on the circuit board 5. The light-emitting component 6 uses a combination of 2700K warm light LED beads and 6500K cool light LED beads array (10 beads each). When the second adjustment knob 4 is rotated, the pulse signal is converted from analog to digital and controls the PWM duty cycle of the two LED bead arrays (adjustment range 0-100%): when rotated clockwise, the proportion of cool light increases and the color temperature rises linearly from 2700K to 6500K; when rotated counterclockwise, the proportion of warm light increases and the color temperature is adjusted in the opposite direction, and the total brightness remains constant during the adjustment process (achieved through a brightness compensation algorithm).

[0050] Even better, both knobs offer a 360° continuous rotation. The noise adjustment of the first knob 3 corresponds to the "0-10" scale marked on the edge of the knob (0 being the lowest noise level and 10 the highest), with each level corresponding to a 0.5% change in ripple coefficient. The second knob 4 achieves warm and cool light mixing through PWM duty cycle adjustment. Compared to switching between single color temperature LEDs, this provides a stepless, smooth transition across the entire 2700K-6500K range, while maintaining constant brightness during adjustment, avoiding fluctuations in fill light intensity due to color temperature changes. This feature is particularly suitable for professional needs such as skin tone reproduction in live streaming and color matching in product photography.

[0051] Furthermore, at least one side wall of the bottom shell 2 is provided with a mounting member 22, the mounting member 22 including a metal sleeve, the metal sleeve having an internal thread.

[0052] The internally threaded metal sleeve mounting piece 22 can be directly connected to industry-standard external devices such as tripods, extension poles, and clamps, allowing the fill light to be used not only handheld but also fixed to a desktop, tripod, or other supporting structure, adapting to various installation needs. For example, during live streaming, the bottom mounting piece 22 can be used to fix it to a desktop stand, freeing up the hands; during outdoor shooting, the side mounting piece 22 can be used to connect to an extension pole for high-altitude fill lighting.

[0053] Furthermore, a slot 21 is provided on one side wall of the bottom shell 2, and the slot 21 is T-shaped.

[0054] The T-shaped slot 21 provides a quick connection method for the fill light, and can be used with various specialized accessories such as lanyards, filter holders, and portable stands. The slot 21 is integrally molded with the bottom shell 2, requiring no additional assembly parts, without increasing the product's weight or size. Its reasonable positioning ensures that it does not interfere with the mounting parts 22, adjustment knobs, and other components, maintaining the compactness of the overall fill light structure while expanding its functionality.

[0055] Furthermore, the bottom shell 2 is provided with a plurality of positioning blocks 24, and positioning grooves are formed between the positioning blocks 24, and the energy storage power supply 7 is snapped into the positioning grooves.

[0056] Specifically, the positioning blocks 24 and the bottom shell 2 are integrally injection molded from ABS engineering plastic, and there are four of them, located on the inner wall of the bottom shell 2 corresponding to the four corners of the energy storage power supply 7. Each positioning block 24 has a right-angled trapezoidal structure. The top edge of the positioning block 24 has a 15° guide slope to facilitate the insertion of the energy storage power supply 7 into the positioning groove; the bottom of the positioning groove has two parallel heat dissipation grooves on the inner wall of the bottom shell 2, which contact the bottom of the energy storage power supply 7, without affecting heat dissipation and increasing contact friction. After the energy storage power supply 7 is inserted into the positioning groove, its top surface is flush with the top surface of the positioning block 24.

[0057] The positioning groove formed by the positioning block 24 is precisely matched with the energy storage power supply 7. Through the clamping force of the four corners and the friction of the TPU anti-slip layer, the energy storage power supply 7 can be firmly locked in place, preventing the supplementary light from shifting when it is shaken, dropped, or moved violently, preventing the connection line between the power supply and the circuit board 5 from being damaged by pulling, and ensuring the stability of the circuit connection.
