Description

Technical Field

[0001] This utility model relates to the field of supplementary lighting technology, and in particular to a supplementary lighting device for live broadcast television. Background Technology

[0002] Watching live news broadcasts on mobile phones or televisions to learn about national and provincial conditions is a daily habit for many people. The release of these live broadcasts or videos requires a lot of pre-production shooting preparation. During the preparation process, personnel and equipment must be adjusted to their best condition. Among them, supplementary lighting equipment is indispensable. During the shooting process, supplementary lighting equipment can illuminate some dead corners of the venue, increase the brightness of the work site, and make the people in the lens more realistic and clear. Reasonable use of supplementary lighting equipment can improve the facial condition of the staff under the lens, show a better mental appearance, and present a better shooting effect.

[0003] However, during the filming process, the location will be changed from indoor to outdoor depending on the needs of the work, and the weather conditions will also change every day. These different working environments result in poor lighting conditions at the filming location. The faces of the staff under the lens are dark and blurry, and the makeup cannot be effectively displayed. The current lighting equipment only has one front fill light, and the fill light angle is singular. There are still shadows in the lower half of the face of the staff, and the face is not brightened enough, resulting in poor shooting effect. Utility Model Content

[0017] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0018] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0019] Please see Figure 1 A broadcast television live lighting device includes a tripod 1, a support rod 2 fixedly installed inside the tripod 1, a mounting platform 3 fixedly installed on the top of the support rod 2, a support diagonal rod 4 fixedly connected between the mounting platform 3 and the support rod 2, a groove 5 opened at one end of the mounting platform 3, a multi-angle lighting component 6 installed in the groove 5 to meet the working requirements of lighting at different angles, a clamping component 7 installed at the end of the mounting platform 3 away from the multi-angle lighting component 6, an adjustable lifting component 8 installed on the top of the mounting platform 3 near the groove 5, the adjustable lifting component 8 and the clamping component 7 cooperate to support and stabilize the camera, which is beneficial to the stability of shooting, and a front lighting ring 9 installed on the outer side of the mounting platform 3 near the adjustable lifting component 8 to provide front lighting for the staff and improve facial brightness.

[0020] Furthermore, such as Figure 2 As shown, circular grooves 10 are respectively provided on both sides of the interior of the groove 5, and the interior of the circular grooves 10 is fixedly connected to the multi-angle supplementary lighting component 6.

[0021] Furthermore, in order to achieve multi-angle adjustment of the bottom fill light ring, such as Figures 2-3As shown, the multi-angle supplementary lighting component 6 includes a lamp holder 61, with gears 62 fixedly connected to both sides of the lamp holder 61. The gears 62 are rotatably connected to the circular groove 10. Each gear 62 has a limiting part 63 between adjacent teeth to restrict the rotation of the gear 62. A bottom supplementary lighting ring 64 is electrically connected to the side of the lamp holder 61 away from the groove 5. The limiting part 63 includes a limiting housing 631, one side of which is fixedly connected to the inner wall of the circular groove 10. A limiting block 632 is slidably connected inside the limiting housing 631. The limiting block 632 meshes with the gear 62. A first spring 633 is provided between the limiting housing 631 and the limiting block 632. One end of the first spring 633 is welded to the inside of the limiting housing 631, and the other end is welded to the limiting block 632. When there is no external force pushing, the first spring 633 is in a stationary state, and the limiting block 632 is locked in the gear. Between the teeth of wheel 62, the rotation of gear 62 is prevented. When the angle of the bottom supplementary light ring 64 needs to be adjusted, the lamp holder 61 is pushed, and the thrust is transmitted to gear 62. The teeth of gear 62 compress the limiting block 632. The limiting block 632 compresses the first spring 633 and slides towards the bottom of the limiting housing 631. When the limiting block 632 is compressed to the point that it can no longer block the teeth of gear 62, gear 62 rotates, driving the lamp holder 61 to rotate, thereby driving the bottom supplementary light ring 64 to rotate. When the teeth of gear 62 rotate between two adjacent limiting blocks 632, the limiting block 632 is no longer compressed by the teeth. Under the elastic force of the first spring 633, it slides outward along the limiting housing 631, returns to its original position, and locks between the teeth, restricting the rotation of gear 62, thereby restricting the rotation of lamp holder 61, and finally restricting the rotation of bottom supplementary light ring 64, making it stable in the required position and completing the angle adjustment.

[0022] Furthermore, to improve the stability of the camera on the lighting equipment, such as... Figure 3 As shown, the adjustable lifting assembly 8 includes a base 81, the bottom of which is fixedly connected to the mounting platform 3. A lifting platform 82 is slidably connected inside the base 81. The top of the lifting platform 82 is designed with a semi-circular groove to facilitate receiving the camera lens. A vertical first sliding groove 83 is provided on the side of the lifting platform 82 near the multi-angle supplementary lighting assembly 6. A through hole 84 is provided on the side of the base 81 near the multi-angle supplementary lighting assembly 6. A bolt 85 is threaded into the through hole 84. One end of the bolt 85 is slidably connected to the first sliding groove 83, and the other end is welded with a rotating wheel 86. When the camera is placed on the mounting platform 3 and the lens is mounted above the lifting platform 82, the rotating wheel 86 is rotated counterclockwise, and the bolt 85 is screwed outward, raising the lifting platform 82 until it abuts against the camera lens. When the rotating wheel 86 is rotated clockwise, the bolt 85 is screwed inward into the first sliding groove 83, pressing the lifting platform 82 against the inner wall of the base 81, fixing the position of the lifting platform 82, and completing the supporting function of the adjustable lifting assembly 8 for the lens.

[0023] Furthermore, to improve the stability of the camera body, such as... Figures 4-5 As shown, the clamping assembly 7 includes two extension platforms 71. Each extension platform 71 has a second slide groove 72 on its top. A clamping block 73 is slidably connected inside each second slide groove 72. A second spring 74 is provided between the side of the clamping block 73 away from the mounting platform 3 and the second slide groove 72. One end of the second spring 74 is welded to the clamping block 73, and the other end is welded to the inner wall of the second slide groove 72. A ramp is provided on the opposite side of the two clamping blocks 73. The camera slides down the ramp under its own weight. The two clamping blocks 73 automatically slide to both sides along the second slide groove 72 under the pushing force of the camera. When the bottom of the camera is close to the mounting platform... After contact, clamping block 77 stops sliding to both sides, and second spring 74 is compressed, generating an elastic force opposite to the direction of compression, pushing clamping block 73 towards the camera, thereby clamping the camera body. To further stabilize the camera body, a slide rod 75 is provided inside the second spring 74. One end of the slide rod 75 is fixedly connected to clamping block 73, and the other end passes through extension platform 71 and is slidably connected to it. A mounting housing 76 is provided on the outer side of the end of slide rod 75 that passes through extension platform 71. One side of mounting housing 76 is fixedly connected to extension platform 71. A locking block 77 is engaged inside mounting housing 76. The upper part of locking block 77 is connected, and the lower part has a slot. The locking block 77 has two rubber pads 78 fixedly connected inside, each rubber pad 78 slidingly contacting the slide rod 75. The rubber pads 78 increase the friction with the slide rod. A quick-release latch 79 is provided on the outer side of the mounting housing 76. The quick-release latch 79 includes a pin 791, which passes through the locking block 77 and the mounting housing 76. One end of the pin 791 is threadedly connected to a retaining ring 792, which prevents the pin 791 from dislodging from the locking block 77. The other end of the pin 791 is welded to a connecting shaft 793, and both ends of the connecting shaft 793 are hinged to eccentric handles 794. The eccentric handles 794 are connected to the mounting housing 76. A washer 795, which is penetrated by a pin 791, is provided between the camera body and the mounting housing 76. The washer 795 abuts against the locking block 77. When the camera body contacts the mounting platform 3, the slide rod 75 stops as the clamping block 73 stops. Rotating the eccentric handle 794 downward causes the eccentric circle to rotate inward around the connecting shaft 793, pressing the washer 795. The washer 795 presses the locking block 77 inward, and the gap at the bottom of the locking block 77 becomes smaller under the pressure. This causes the rubber gasket 78 inside the locking block 77 to clamp the slide rod 75, preventing the slide rod 75 from moving due to working vibration, thus preventing the clamping block 73 from loosening and ensuring the stability of the camera during operation.

[0024] Operating Procedure: When live broadcasting is required, place the broadcast television live lighting equipment in a suitable position, place the camera body between two clamping blocks 73, and the camera slides down the slope under its own weight. The clamping blocks 73 slide to both sides until the bottom of the camera body contacts the mounting platform 3. The clamping blocks 73 clamp the camera under the push of the second spring 74. Rotate the eccentric handle 794 downwards, and the eccentric circle presses the washer 795 inwards. The washer 795 presses the locking block 77, which in turn clamps the slide rod 75. Finally, the clamping blocks 73 clamp the camera body. Rotate the wheel 86 outwards, and the bolt 85 disengages from the first slide groove 83. Raise the lifting platform 82 until it supports the camera lens. Tighten the bolt 85 inwards to fix the height of the lifting platform 82, providing support for the lens and improving the stability of the camera during shooting.

[0025] Turn on the front fill light ring 9 to increase the brightness of the person in front of the live streamer. Turn on the bottom fill light ring 64. Rotate the lamp holder 61. The gear 62 is compressed by the force of the limiting block 632. The limiting block 632 slides towards the bottom of the limiting housing 631, and the restriction on the gear 62 is removed. The gear 62 rotates, driving the bottom fill light ring 64 to rotate. When the gear teeth rotate between the adjacent limiting blocks 632, the limiting blocks 632 return to their original position under the elastic force of the first spring 633, locking between the gear teeth and restricting the rotation of the gear 62. Finally, the rotation of the bottom fill light ring 64 is restricted. Depending on the lighting needs of the live stream, rotate the lamp holder 61 clockwise or counterclockwise to drive the bottom fill light ring 64 to rotate. Finally, adjust the bottom fill light ring 64 to a suitable position to increase the brightness of the person's face and enhance the shooting effect.
