[0024] To enable those skilled in the art to better understand the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0025] like Figure 1-5As shown, a photographic fill light with extended battery life includes a fill light body 1 and a backup battery pack 2. The fill light body 1 houses a main control circuit board 3 and a power supply battery 4. The power supply battery 4 is electrically connected to the main control circuit board 3. The main control circuit board 3 can employ conventional circuit designs in the prior art to control the operation of the fill light body 1. The power supply battery 4 provides power to the fill light body 1. A first magnetic element 5 is provided on the rear end face of the fill light body 1, and a second magnetic element 6 is provided on the front end face of the backup battery pack 2 at a corresponding position to the first magnetic element 5. The first magnetic element 5 and the second magnetic element 6 are magnetically connected. Through the magnetic connection between the first magnetic element 5 and the second magnetic element 6, the fill light body 1 and the backup battery pack 2 can be quickly installed and removed.

[0026] The backup battery pack 2 contains a backup battery 7. The rear end face of the supplementary light body 1 is provided with a first contact electrode 8, which is electrically connected to the main control circuit board 3. The front end face of the backup battery pack 2 is provided with a second contact electrode 9 at a position corresponding to the first contact electrode 8. The second contact electrode 9 is electrically connected to the backup battery 7, and the first contact electrode 8 can abut against the second contact electrode 9 to conduct electricity.

[0027] Normally, the backup battery pack 2 can be removed from the fill light body 1 and powered by the power supply battery 4. When the power supply battery 4 is low on power, the user can align the first magnetic component 5 and the second magnetic component 6 to magnetically connect and fix them together, thereby connecting and fixing the backup battery pack 2 to the fill light body 1. After the fill light body 1 and the backup battery pack 2 are magnetically connected and fixed, the first contact electrode 8 and the second contact electrode 9 come into contact and conduct, thereby enabling the backup battery 7 to power the fill light body 1.

[0028] This photographic fill light features a removable spare battery pack 2, extending its operating time and meeting the needs of extended outdoor shooting. Furthermore, the magnetic connection allows for quick and easy connection and disconnection between the fill light unit 1 and the spare battery pack 2, making operation simple and convenient.

[0029] In this embodiment, the first magnetic element 5 is an iron ring, and the second magnetic element 6 is a magnet ring. The ring arrangement provides a uniform and stable magnetic attraction force, making the structural layout more reasonable. In other embodiments, the first magnetic element 5 can be a magnet, the second magnetic element 6 can be an iron ring, or both magnetic elements can be magnets, as long as the polarities of their mating surfaces are opposite.

[0030] To facilitate quick installation and alignment, an alignment protrusion 101 is provided on the rear end face of the supplementary light body 1, and a handheld slot 21 adapted to the alignment protrusion 101 is provided on the front end face of the spare battery pack 2, allowing the alignment protrusion 101 to be inserted into the handheld slot 21. When installing the spare battery pack 2, the handheld slot 21 is aligned and inserted into the alignment protrusion 101. At this time, the first magnetic component 5 and the second magnetic component 6 will attract each other until they are mutually attracted; in addition, the first contact electrode 8 and the second contact electrode 9 can also be made in contact and conduction. On the other hand, the handheld slot 21 also makes it easier for the user to hold the spare battery pack 2, improving portability.

[0031] The rear end face of the supplementary light body 1 has four rectangular positioning slots 102. The front end face of the spare battery pack 2 has corresponding positioning protrusions 22 at positions corresponding to the positioning slots 102. After the spare battery pack 2 is magnetically connected and fixed to the supplementary light body 1, the positioning protrusions 22 engage with their respective positioning slots 102. The cooperation between the positioning protrusions 22 and the positioning slots 102 enhances the stability of the connection between the spare battery pack 2 and the supplementary light body 1, ensuring a secure magnetic connection.

[0032] In other embodiments, the number of positioning slots 102 and positioning protrusions 22 can be any other number, as long as they correspond one-to-one.

[0033] The backup battery pack 2 can be used as a backup battery 7 to power the fill light body 1, and can also be used as a power bank on its own. In order to ensure that the backup battery pack 2 can be placed stably on the table, in this embodiment, a soft rubber pad 10 is installed at the end of each positioning protrusion 22. The soft rubber pad 10 can be made of silicone or rubber material.

[0034] The backup battery pack 2 contains a second circuit board 11, and the second contact electrode 9 and the backup battery 7 are electrically connected to the second circuit board 11. The backup battery pack 2 is equipped with a power indicator mechanism, which is electrically connected to the second circuit board 11 and is used to display the power level of the backup battery 7. Users can check the remaining power level of the backup battery pack 2 in real time by viewing the power indicator mechanism, improving its usability.

[0035] Specifically, the rear end face of the backup battery pack 2 is provided with an annular mounting boss 23. The power indicator mechanism includes indicator lights 12 arranged in a circular array on the second circuit board 11. A light guide 13 is provided on the annular mounting boss 23, and a light guide section 14 is provided at the corresponding position of the light guide 13 and the indicator lights 12. The light emitted by the indicator lights 12 can pass through the light guide section 14 and be emitted outward, making it convenient for users to check the power status. In practical applications, it can be set that all indicator lights 12 light up when the backup battery 7 is fully charged, and the indicator lights 12 can turn off accordingly as the power gradually decreases. Users can know the power status in time by checking the illumination of the light guide section 14. The use of annular scale distribution of the light guide section 14 can improve the overall aesthetics of the power display, making the backup battery pack 2 more technological and improving the user experience.

[0036] A wireless charging module 15 is housed within the annular mounting boss 23, and a charging / discharging connector 16 is provided on the side wall of the backup battery pack 2. The wireless charging module 15 and the charging / discharging connector 16 are electrically connected to the second circuit board 11. Both the wireless charging module 15 and the charging / discharging connector 16 can charge the backup battery 7 from an external power source, and can also serve as a power source for other devices when needed. By simultaneously providing the wireless charging module 15 and the charging / discharging connector 16, the backup battery pack 2 supports both wireless and wired charging / discharging methods. Any existing type of wireless charging module 15 and charging / discharging connector 16 can be used, and this invention does not impose any limitations on this.

[0037] The fill light body 1 has a fixedly installed LED mounting plate 17, which is electrically connected to the main control circuit board 3. Multiple LEDs 18 are arrayed on the LED mounting plate 17. The front end of the fill light body 1 has a light-transmitting glass 19. When the fill light body 1 is working, the power supply battery 4 supplies power to the LEDs 18, and the light emitted by the LEDs 18 passes through the light-transmitting glass 19 and is emitted outward, achieving the purpose of supplementing the lighting of the shooting scene.

[0038] To facilitate user operation and control, the fill light body 1 is equipped with a power switch 20, a display screen 24, and an adjustment switch 25. The power switch 20, display screen 24, and adjustment switch 25 are electrically connected to the main control circuit board 3. Users can adjust the brightness and color temperature parameters of the fill light using the adjustment switch 25 and observe the current operating status through the display screen 24.

[0039] Considering the heat dissipation requirements of the LED chip 18, the housing on the fill light body 1 where the LED chip mounting plate 17 is installed can be made of aluminum alloy with good thermal conductivity. A heat dissipation aluminum plate 26 is fixedly installed inside the fill light body 1, so that the heat dissipation aluminum plate 26 abuts against the side wall of the fill light body 1, and at the same time, the heat dissipation aluminum plate 26 also abuts tightly against the back of the LED chip mounting plate 17. In this way, the heat generated by the LED chip 18 can be conducted through the LED chip mounting plate 17 to the heat dissipation aluminum plate 26, and then to the outer shell of the fill light body 1, and then dissipated into the air, ensuring that the fill light body 1 can work stably for a long time.

[0040] Working principle:

[0041] Normally, the fill light body 1 is powered by the power supply battery 4. When the power supply battery 4 is low on power, the user can hold the spare battery pack 2 and align the handheld slot 21 with the alignment protrusion 101, and simultaneously align the positioning protrusion 22 with the positioning slot 102. This causes the handheld slot 21 to snap into the alignment protrusion 101 and the positioning protrusion 22 to insert into the corresponding positioning slot 102. At this time, the first magnetic component 5 and the second magnetic component 6 attract each other, making the fill light body 1 and the spare battery pack 2 tightly connected. At the same time, the first contact electrode 8 and the second contact electrode 9 abut and conduct. The spare battery 7 supplies power to the fill light body 1 through the second circuit board 11 and the second contact electrode 9, thereby extending the fill light's battery life.

[0042] When the backup battery pack 2 is low on power, it can be charged wirelessly or via wired charging. Users can monitor the remaining power of the backup battery 7 in real time by observing the illumination of the light guide 14, facilitating timely charging. Furthermore, the backup battery pack 2 can also be used independently as a power bank to charge other electronic devices.

[0043] The above-described specific embodiments are preferred embodiments of this utility model, and are not intended to limit the specific scope of this utility model. The scope of this utility model includes but is not limited to the specific embodiments described above. All equivalent changes made in accordance with this utility model are within the protection scope of this utility model.
