Description

Technical Field

[0001] This application relates to the field of photographic fill light technology, specifically to a photographic fill light with a replaceable lamp head. Background Technology

[0002] As an important artificial light source, photographic fill lights are widely used in the fields of photography and video shooting. Their function is to compensate for insufficient ambient light, achieve precise control and artistic shaping of light, thereby improving image quality.

[0003] Existing photographic fill lights typically consist of two parts: a lamp head and a lamp holder, with the light source integrated inside the lamp head. Currently, the lamp head and lamp holder are generally connected and fixed using mechanical fasteners such as screws. This connection method reveals significant limitations in practical use: when the shooting scene or subject changes, for example, when different color temperatures, brightness, or lighting effects (such as spotlighting or floodlighting) are needed, users often need to replace the fill light with one that has the corresponding characteristics. Because the lamp head and lamp holder are fixedly connected, the entire fill light must be removed from the camera or other shooting equipment before the new fill light can be installed. This process is cumbersome, time-consuming, and disruptive, disrupting the continuity of shooting and affecting creative efficiency. Utility Model Content

The terms "first," "second," etc., in the specification, claims, or foregoing drawings of this application are used to distinguish different objects, not to describe a particular order.

[0022] In this application, the reference to "embodiment" means that a specific feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places in the specification does not necessarily refer to the same embodiment, nor is it a mutually exclusive, independent, or alternative embodiment to other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described in this application can be combined with other embodiments.

[0023] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings.

[0024] like Figure 1-4 As shown, a photographic fill light with a replaceable lamp head includes a lamp head assembly 100 and a lamp holder assembly 200. The lamp head assembly 100 and the lamp holder assembly 200 are detachably magnetically connected, thereby facilitating the replacement of the lamp head and improving ease of use.

[0025] Specifically, the lamp holder assembly 200 includes a lamp holder housing 1. A fixing mechanism 2 is provided on the side wall of the lamp holder housing 1. The fixing mechanism 2 is used to mount and fix the entire fill light to a camera, tripod head, or other shooting equipment. The fixing mechanism 2 can be a cold shoe interface, a connecting slot, or other structures, and this utility model does not limit this. A control board 3 is fixedly installed inside the lamp holder housing 1, responsible for the power management, signal processing, and function control of the entire fill light. A recessed lamp head mounting groove 4 is provided at the front end of the lamp holder housing 1. A first magnetic element 5 and a first contact electrode 6 are provided in the lamp head mounting groove 4. The first contact electrode 6 is electrically connected to the control board 3 via a wire or printed circuit. The first contact electrode 6 slightly protrudes from the front end face of the lamp head mounting groove 4 to ensure good contact with the lamp head assembly 100.

[0026] The lamp holder assembly 100 includes a lamp holder housing 7, inside which a light source serving as the light-emitting core is installed. At the rear end of the lamp holder housing 7, a mounting boss 8 is provided, which is adapted to the shape and size of the lamp holder mounting groove 4. A second magnetic element 9 and a second contact electrode 10 are disposed within the mounting boss 8. The first magnetic element 5 and the second magnetic element 9 are magnetically connected; the second contact electrode 10 is electrically connected to the light source and extends out of the end face of the mounting boss 8; the first contact electrode 6 can abut against the second contact electrode 10 for electrical connection.

[0027] When the lamp holder assembly 100 needs to be installed, simply align the mounting protrusion 8 with the lamp holder mounting slot 4 and insert it. Due to the mutual magnetic attraction between the first magnetic component 5 and the second magnetic component 9, they will quickly attract each other, firmly fixing the lamp holder assembly 100 onto the lamp holder assembly 200. At the same time, the first contact electrode 6 and the second contact electrode 10 also come into contact with each other due to the fit of the components, realizing the conduction of the circuit. The electrical energy and control signals output by the control board 3 are transmitted to the light source through the cooperation of the two contact electrodes, enabling it to work normally. During disassembly, simply apply a pulling force sufficient to overcome the magnetic attraction to separate the lamp holder assembly 100 from the lamp holder assembly 200; the process is simple and quick.

[0028] This photographic fill light achieves rapid attachment and separation between the lamp head assembly 100 and the lamp base assembly 200 through the magnetic connection of the first magnetic component 5 and the second magnetic component 9. Users can replace the lamp head manually without any tools, making the operation extremely simple and quick, greatly improving shooting efficiency, and is especially suitable for scenes requiring frequent switching of lighting effects. Furthermore, the magnetic cooperation between the first magnetic component 5 and the second magnetic component 9 ensures a tight contact between the first contact electrode 6 and the second contact electrode 10, forming a stable, low-resistance electrical connection. This guarantees the reliability of power and signal transmission and avoids problems such as light flickering or failure due to poor contact.

[0029] In this embodiment, the first magnetic element 5 is an iron ring, and the second magnetic element 9 is a magnet ring. The ring arrangement provides a uniform and stable magnetic attraction force, while the space in the middle can be used to arrange the first contact electrode 6 and the second contact electrode 10, or to provide space for wiring, making the structural layout more rational. In other embodiments, the first magnetic element 5 can be a magnet, the second magnetic element 9 can be an iron ring, or both magnetic elements can be magnets, as long as the polarities of their mating surfaces are opposite.

[0030] The lamp holder housing 1 also houses a battery 11, which is electrically connected to the control board 3. This allows the fill light to operate independently without an external power source, improving its portability and flexibility.

[0031] To facilitate user operation and monitoring, the lamp holder housing 1 is also equipped with a power switch 12, a display screen 13, and an adjustment switch 14. The power switch 12, display screen 13, and adjustment switch 14 are electrically connected to the control board 3. Users can adjust the brightness and color temperature parameters of the supplementary light using the adjustment switch 14, and observe the current operating status through the display screen 13.

[0032] In addition, a charging / discharging connector 15 (such as a USB Type-C interface) is provided on the side wall of the lamp holder housing 1, which is electrically connected to the control board 3. The charging / discharging connector 15 can be used to charge the built-in battery 11, or it can be used as a power source to power other devices when needed, or it can receive external power input.

[0033] The light source includes a lamp bead mounting plate 16, which is fixedly connected to the lamp holder housing 7. Multiple lamp beads 17 are mounted on the lamp bead mounting plate 16. A pressure ring 18 is fixed to the front end of the lamp holder housing 7 by means of threads or clips, and a light-transmitting glass 19 is embedded in the pressure ring 18. The light emitted by the lamp beads 17 can pass through the light-transmitting glass 19 and be emitted.

[0034] Considering the heat dissipation requirements of the LED chip 17, the lamp holder housing 7 is preferably made of aluminum alloy material with good thermal conductivity. The lamp holder housing 7 may have an internal mounting step 71, on which a heat dissipation aluminum plate 20 is fixed, and the heat dissipation aluminum plate 20 is in close contact with the back of the LED chip mounting plate 16. In this way, the heat generated by the LED chip 17 can be conducted through the LED chip mounting plate 16 to the heat dissipation aluminum plate 20, and then dissipated into the air through the large-area aluminum alloy lamp holder housing 7, ensuring stable operation of the lamp holder for extended periods.

[0035] To improve light efficiency and make the light more uniform and softer, a diffuser lens 21 can also be provided on the lamp bead mounting plate 16. The front end of the diffuser lens 21 abuts against the inner surface of the light-transmitting glass 19. A conical diffuser portion 22 is machined on the diffuser lens 21 at the corresponding position of each lamp bead 17. The conical diffuser portion 22 fits precisely around the corresponding lamp bead 17, diffusing and spreading the light emitted by the lamp bead 17, thereby making the outward reflection of the light emitted by the lamp bead 17 more uniform.

[0036] Furthermore, to achieve a softer lighting effect and avoid harsh shadows, a semi-transparent diffuser 23 can be fitted onto the front end of the lamp holder housing 7. The semi-transparent diffuser 23 can be fixedly connected to the pressure ring 18 by clips or threads, and completely covers the front light-transmitting glass 19. The light emitted by the lamp beads 17 passes sequentially through the diffuser lens 21, the light-transmitting glass 19, and finally through the semi-transparent diffuser 23, forming a very soft and uniform surface light.

[0037] The above-described specific embodiments are preferred embodiments of this application and are not intended to limit the specific scope of this application. The scope of this application includes but is not limited to the specific embodiments described herein. All equivalent changes made in accordance with this application are within the protection scope of this application.
