Description

Technical Field

[0001] This utility model relates to the field of fill light technology, and in particular to a high-power fill light. Background Technology

[0002] High-power fill lights are devices with powerful illumination capabilities, widely used in photography, videography, live streaming, security, and other fields. In portrait photography, high-power fill lights can illuminate the face, highlight facial features, create different lighting atmospheres, and make the subject more three-dimensional and lifelike. In product photography, they can clearly showcase product details, texture, and color, enhancing the product's visual appeal. In film and television shooting, they can create various lighting effects according to different scenes and plot requirements, enhancing the depth and artistic appeal of the image. High-power fill lights are relatively large, and inevitably generate a lot of heat during operation. Existing high-power fill lights typically have ventilation grilles on the casing, achieving natural convection cooling through air exchange with the outside environment. However, this method is ineffective, easily leading to heat accumulation inside the fill light and inability to dissipate it effectively. Some fill lights incorporate fans on the casing to achieve forced convection cooling, improving heat dissipation. However, existing fan-cooled fill lights usually only cool the light source component, failing to address the controller's cooling. Overheating of the controller can also cause the fill light to malfunction.

[0003] Therefore, it is necessary to improve existing high-power supplementary lights to overcome the shortcomings of existing technology. Utility Model Content

Detailed Implementation

[0029] 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.

[0030] Existing high-power fill lights typically use ventilation grilles on the housing to exchange air with the outside environment for natural convection cooling. However, this method is ineffective and can easily lead to heat buildup inside the fill light, making it difficult to dissipate effectively. Some fill lights incorporate fans in the housing to achieve forced convection cooling, thus improving heat dissipation. However, existing fan-cooled fill lights usually only cool the light source component and cannot adequately cool the controller. Overheating of the controller can also cause the fill light to malfunction.

[0031] Based on this, this application provides a high-power supplementary light.

[0032] Example

[0033] See Figures 1-2 This embodiment provides a high-power supplementary light, including a housing 100. A light source component 200 is provided on one side of the housing 100, and a control device is provided on the opposite side. The control device includes a circuit board 300, which is fixed in the housing 100.

[0034] A first heat sink 600 is provided between the circuit boards 300 and the circuit boards 300. The first heat sink 600 has multiple parallel first air ducts 610. One side of the first heat sink 600 is connected to the light source component 200. A cooling fan 400 is fixed to one side of the first heat sink 600 and is oriented toward the first air duct 610.

[0035] A second heat sink 500 is provided on one side of the circuit board 300, and one side of the second heat sink 500 is connected to the cooling fan 400. Further, the second heat sink 500 includes a second substrate 520 and multiple fins 510. The second substrate 520 is fixed on the housing 100 and one side is connected to the circuit board 300. The fins 510 are fixed on the side of the second substrate 520 near the cooling fan 400, and a second air duct is formed between two adjacent fins 510.

[0036] Specifically, the interior is provided with multiple parallel first air ducts 610, one side of which is directly connected to the light source component 200 (for dissipating heat from the light source). More specifically, the light source component 200 is located at the bottom of the housing 100, and the control device is located at the top of the housing 100. The first air ducts 610 of the first heat sink 600 are arranged along the height direction of the housing 100, and the first air ducts 610 are parallel to each other. Specifically, the first heat sink 600 includes multiple layers of parallel aluminum plates, with the first air ducts 610 formed between adjacent aluminum plates. The bottom of the first heat sink 600 is connected to the aluminum substrate of the light source component 200 through thermally conductive silicone grease.

[0037] A second heat sink 500 is provided on the outer side of the circuit board 300 near the right side of the housing 100. The second heat sink 500 has an aluminum fin structure. The left side of the second heat sink 500 is connected to the air inlet of the cooling fan 400 through a thermal pad.

[0038] The first heat sink 600 is directly connected to the light source component 200 and can quickly absorb the heat generated by the LED beads. When the cooling fan 400 blows air into the first air duct 610, the airflow flows rapidly in the air duct and can quickly carry away the heat. At the same time, the second heat sink 500 absorbs the heat of the circuit board 300. During operation, the cooling fan 400 can simultaneously drive the airflow around the second heat sink 500 to achieve heat dissipation for the control device.

[0039] The aforementioned high-power supplementary lighting lamp features a novel structure that achieves dual heat dissipation through a single cooling fan 400 via a clever design. On one hand, when the fan blows air into the first air duct 610, the heat generated by the light source component 200 is efficiently dissipated through the first heat sink 600. On the other hand, the fan, connected to the second heat sink 500, simultaneously removes heat generated by the circuit board 300 (control device). This design simplifies the structure and effectively reduces the operating temperature rise of the light source component 200 and the control device, ensuring the long-term stability of the supplementary lighting lamp during high-power operation. It solves the problems of insufficient heat dissipation efficiency and susceptibility to overheating affecting the lifespan of traditional supplementary lighting lamps.

[0040] By cleverly arranging the first heat sink 600, the cooling fan 400, and the second heat sink 500, a single cooling fan 400 can simultaneously dissipate heat from the light source component 200 and the control device, reducing the number of heat dissipation components, making the overall structure of the fill light more compact, saving internal space, and reducing production costs.

[0041] Furthermore, the peripheral wall of the second substrate 520 abuts against the inner wall of the housing 100, and the second substrate 520 and one side of the housing 100 form a first mounting cavity 140. The control device is disposed in the first mounting cavity 140, and the circuit board 300 is connected to the second substrate 520.

[0042] The second substrate 520 abuts against the inner wall of the housing 100 to form a first mounting cavity 140, so that after the circuit board 300 is installed in the first mounting cavity 140, it is in a relatively sealed state, thereby protecting the circuit board 300. That is, the first mounting cavity 140 plays a role in waterproofing and dustproofing the circuit board 300, which can extend the service life of the circuit board 300.

[0043] Furthermore, the second substrate 520 forms a second mounting cavity with one side of the housing 100, and the light source component 200 is disposed in the second mounting cavity; at least one side wall of the second mounting cavity is provided with an air inlet grille 110.

[0044] The air grille provides a stable source of cool air for the second mounting cavity. When the cooling fan 400 is working, a negative pressure is formed in the first air duct 610, which draws in low-temperature air from the outside through the air intake grille 110. The cool air first flows over the surface of the light source component 200, directly carrying away some of the heat, and then enters the air duct of the first heat sink 600. This forms a dual circulation of "external cool air supply + internal forced convection" with the original heat dissipation path, thereby improving heat dissipation efficiency.

[0045] Furthermore, the exterior of the housing 100 is also provided with a mounting frame, which includes two cantilever arms 1 arranged opposite each other, and each end of the cantilever arm 1 is provided with a connecting shaft 3, which is hinged to the cantilever arm 1.

[0046] At least one of the cantilever 1 is provided with a limiting structure 4, the limiting structure 4 including a limiting block 41 and an adjusting structure 42, the limiting block 41 being disposed on one side of the cantilever 1, and the adjusting structure 42 being used to drive the limiting block 41 to move, thereby causing the limiting block 41 to move away from or closer to the cantilever 1; the mounting bracket also includes a crossbeam 2 connected between the two cantilever 1s.

[0047] Furthermore, the adjustment structure 42 includes an adjustment handle 422, which is fixed to the cantilever 1 and located on the side of the cantilever 1 opposite to the limiting block 41.

[0048] An adjusting screw 421 is provided on the adjusting handle 422, and one end of the adjusting screw 421 passes through the adjusting handle 422, the cantilever 1 and the limiting block 41;

[0049] Rotating the adjusting screw 421 can move the limiting block 41.

[0050] The mounting frame includes two cantilever arms 1 arranged opposite each other, and each end of the cantilever arm 1 is provided with a connecting shaft 3, which is hinged to the cantilever arm 1.

[0051] At least one of the cantilever 1 is provided with a limiting structure 4, the limiting structure 4 including a limiting block 41 and an adjusting structure 42, the limiting block 41 being disposed on one side of the cantilever 1, and the adjusting structure 42 being used to drive the limiting block 41 to move, thereby causing the limiting block 41 to move away from or closer to the cantilever 1.

[0052] Specifically, the mounting bracket includes two opposing cantilever arms 1, which are made of high-strength aluminum alloy or engineering plastic, providing excellent load-bearing capacity while effectively reducing the overall weight of the mounting bracket. Each cantilever arm 1 has a connecting shaft 3 at its end, which is hinged to the cantilever arm 1. Specifically, a hinge hole is provided at the end of the cantilever arm 1, and one end of the connecting shaft 3 is inserted into the hinge hole with a clearance fit, ensuring that the connecting shaft 3 can rotate freely, thus providing a basis for adjusting the angle of the fill light. More specifically, a limiting block 41 is made of hard plastic and is parallel to the cantilever arm 1. A rubber pad 130 is provided on the side wall of the limiting block 41 facing away from the cantilever arm 1. The rubber pad 130 is glued to the limiting block 41 and has a certain degree of elasticity and friction, ensuring effective support against the side wall of the fill light while preventing scratches on the surface of the fill light during support. The adjustment structure 42 includes an adjustment handle 422 and an adjustment screw 421. The adjustment handle 422 is fixed to the cantilever 1 and located on the side of the cantilever 1 away from the limiting block 41. The adjustment handle 422 is connected to the cantilever 1 by welding, ensuring a stable connection. An adjustment screw 421 is provided on the adjustment handle 422, and the adjustment screw 421 is threadedly connected to the adjustment handle 422. One end of the adjustment screw 421 passes through the adjustment handle 422, the cantilever 1, and the limiting block 41, specifically, the adjustment screw 421 and the limiting block 41 are connected by a bearing, ensuring that when the adjustment screw 421 rotates, it can move the limiting block 41 without rotating itself. Rotating the adjustment screw 421 can move the limiting block 41, allowing it to move away from or closer to the cantilever 1. When the limiting block 41 moves away from the side wall of the supplementary light body, the supplementary light body can rotate freely around the connecting shaft 3. The operator can then adjust the angle of the supplementary light to the target position according to actual usage needs. After the angle adjustment is completed, rotate the adjusting screw 421 to push the limiting block 41 towards the side wall of the fill light body until the limiting block 41 is tightly pressed against the side wall of the fill light. Then tighten the nut to lock the position of the bolt, thereby fixing the position of the fill light and ensuring that the fill light will not shift in angle due to external force during use.

[0053] Furthermore, a connecting disc 5 is provided on the connecting shaft 3, and a plurality of mounting holes 51 are provided on the connecting disc 5.

[0054] The connecting disc 5 and multiple mounting holes 51 on the connecting shaft 3 increase the contact area between the connecting shaft 3 and the fill light body. Multiple bolts passing through the mounting holes 51 ensure a more secure connection between the fill light body and the connecting shaft 3, reducing fill light wobbling during use due to loose connections. Furthermore, the multiple mounting holes 51 can accommodate connecting parts on fill light bodies of different specifications, improving the compatibility of the mounting structure with the fill light body and allowing it to be used with a wider range of fill lights.

[0055] Furthermore, the outer casing is provided with a handle 120, and the handle 120 is covered with a rubber pad 130. Specifically, the rubber pad 130 is made of nitrile rubber, and its surface is provided with evenly distributed diamond-shaped anti-slip patterns. The rubber pad 130 is tightly attached to the handle 120 with adhesive, and its edges are flush with the edges of the handle 120 without any lifting. The design of the handle 120 makes the fill light easy to carry and move, solving the problem of inconvenience in handling traditional high-power fill lights due to their large size and weight. Workers can easily move the fill light by holding the handle 120 with one hand, and in outdoor photography scenarios, the position of the fill light can be quickly adjusted, improving work efficiency.

[0056] Furthermore, the first heat sink 600 is also provided with a heat-conducting component 700, which includes a heat-conducting cylinder 710 and a heat-conducting substrate 720. The heat-conducting cylinder 710 is disposed in the first heat sink 600 along the height direction of the first heat sink 600; the heat-conducting substrate 720 is disposed on one side of the heat-conducting cylinder 710 and abuts against the light source component 200.

[0057] The heat-conducting component 700 is made of high thermal conductivity copper. The heat-conducting cylinder 710 is distributed along the height of the first heat sink 600, which can quickly disperse the heat transferred from the light source component 200 through the heat-conducting substrate 720 to various areas of the first heat sink 600. Compared with relying solely on the material of the first heat sink 600 itself to conduct heat, the addition of the heat-conducting component 700 effectively increases the speed at which the heat generated by the light source component 200 is transferred to the first heat sink 600. In addition, the large-area contact between the heat-conducting substrate 720 and the light source component 200 can evenly guide the heat generated by different areas of the light source component 200 into the first heat sink 600. The temperature difference between different areas of the first heat sink 600 is reduced, avoiding local overheating, and allowing the cooling fan 400 to more efficiently dissipate heat through the first air duct 610. The heat-conducting component 700 complements the first air duct 610 and the cooling fan 400. The heat-conducting component 700 is responsible for quickly transferring heat from the light source component 200 to the first heat sink 600 and dispersing it. The first air duct 610 and the cooling fan 400 are responsible for timely dissipating the dispersed heat. The synergistic effect of the two greatly improves the heat dissipation efficiency of the entire heat dissipation system.
