Description

Technical Field

[0001] This invention relates to the field of photography and videography, and more specifically, to a light for photography and videography. Background Technology

[0002] Photography and videography refer to the process of recording images using specialized equipment. Generally, we use mechanical or digital cameras for photography, which is sometimes also called taking pictures. Photography involves exposing a photosensitive medium to light reflected from an object. Videography, on the other hand, uses a video camera to convert optical image signals into electrical signals for storage or transmission. In simpler terms, photography is a static image recording process, while videography is a continuous dynamic image recording process. Photography and videography lights, also known as video fill lights, camera lights, news lights, etc., primarily provide auxiliary light when shooting in low-light conditions to obtain suitable footage. Video fill lights already possess excellent controllability, such as adjusting brightness, color temperature, and displaying remaining battery power. A typical video fill light includes the light body, diffuser, power supply, charger, adapter rod, and other accessories.

[0003] Existing photography and videography lights have poor heat dissipation. During prolonged use, the internal lamp body is prone to overheating and damage, resulting in a short lifespan. Furthermore, after a lamp body malfunctions, it is necessary to wait for it to cool down before it can be disassembled and replaced. The replacement process requires tools and is too cumbersome, making the lamp body replacement process extremely time-consuming and laborious, and also delaying photography and videography work. Therefore, there is an urgent need to design a new photography and videography light. Summary of the Invention

[0015] 3. Beneficial effects Compared with the prior art, the advantages of this invention are: 1. The fill light head has very small air channels on its surface to increase airflow speed and improve heat dissipation. The light control module drives the air to flow rapidly across the fill light body, further enhancing heat dissipation. The fill light head monitors the surface temperature of the fill light body and controls the lamp tube disassembly mechanism when the surface temperature is high. This mechanism then moves the light control module, detaching it from the fill light body and cutting off power. This stops the fill light body from overheating and allows it to gradually cool down, protecting it and extending its lifespan. This improves the practicality of the photographic and video lighting.

[0016] 2. The lighting control module drives the drive mechanism, which in turn moves the synchronizer. The synchronizer rotates the replacement structure 180 degrees, allowing the replacement structure to remove the overheated fill light from the work position and replace it with a room-temperature fill light, preventing it from interfering with video recording and improving work efficiency. The orientation retainer ensures the replaced fill light is stable in the work position, preventing it from deflecting and ensuring proper installation. The fill light head allows for easy opening without tools. The replacement structure enables quick installation and removal of the fill light, facilitating the replacement of damaged fill lights. The operation is time-saving and labor-saving, enhancing the practicality of this photography and video lighting system. Attached Figure Description

[0028] Working principle: First, connect the power module 215 to an external power source, then turn on the power. The cooling fan 512 starts running and drives air through the sealed isolation tube 509, airflow channel 504, replacement chamber 205, and lamp tube perforation 204. Next, the intelligent controller 214 controls the lamp tube mounting motor 601 to run. Then, the lamp tube mounting motor 601 rotates the anti-reverse ratchet 602 and the winding wheel 603. At this time, the ratchet 608 does not obstruct the anti-reverse ratchet 602. Then, the mounting lead 609 winds around the outside of the winding wheel 603 and pulls the linkage slider 612 to the left. At the same time, the tension sensor 614 monitors the tension on the mounting lead 609 in real time and sends the tension data to the intelligent controller 214. The linkage slider 612 applies pressure to the disassembly spring 617, causing the spring 617 to shorten and its elastic potential energy to increase. The linkage slider 612 then moves the sliding column 503 to the left via the linkage slide plate 613. The sliding column 503 then moves the copper socket tube 507 to the left via the radial extension bar 505 and the insulating mounting plate 506. The sliding column 503 then moves into the replacement cavity 205, and the insertion copper post 309 is inserted into the copper socket tube 507. At this point, the supplementary light lamp 308 is electrically connected to the wireless control module 510 via the fixed lamp holder 307, the insertion copper post 309, and the copper socket tube 507. The supplementary light lamp 308 emits light, and then the left side of the insulating mounting plate 506 connects with the moving column... The right side of 306 is attached to each other and a leftward pushing force is applied. Then, the moving column 306 moves to the left, taking the moving slider 305 with it and moving it to the left in sync. Then, the moving slider 305 pulls the corresponding gravity line 311. Next, the gravity line 311 pulls the gravity spring 312. Then, the gravity spring 312 elastically elongates, and its elastic potential energy increases. Then, the moving column 306 moves to the left through the fixed lamp holder 307, taking the supplementary light body 308 with it. Then, the supplementary light body 308 passes through the lamp tube through hole 204 to the left and extends into the interior of the supplementary light cover 12. At this time, the moving column 306 is movably inserted into the interior of the lamp tube through hole 204. Then, the tension data detected by the tension sensor 614 is the same as the preset value inside the intelligent controller 214. Then, the intelligent controller 214... The controller 214 stops the lamp mounting motor 601. Then, the piston 607, under the force of the spring 606, moves the limiting ratchet 608 outwards. The limiting ratchet 608 then engages with the anti-reverse ratchet 602 in one direction, locking it and preventing the winding wheel 603 from rotating. The supplementary light body 308 is then fixed inside the supplementary light cover 12, and is now in its working position. Air flows through the gap between the supplementary light body 308, the moving column 306, and the inner wall of the lamp tube perforation 204, providing heat dissipation. The light emitted by the supplementary light body 308 is then emitted through the supplementary light cover 12, achieving the supplementary lighting effect. Subsequently, as the usage time increases, the surface temperature of the supplementary light body 308 gradually rises.Then, the temperature sensor 203 monitors the surface temperature of the fill light body 308 in real time and sends the monitoring data to the intelligent controller 214. When the surface temperature of the fill light body 308 reaches the preset internal temperature value of the intelligent controller 214, the intelligent controller 214 automatically starts the program to replace the fill light body 308. Then, the intelligent controller 214 controls the electromagnet 605 to work. Next, the electromagnet 605 generates a magnetic attraction force on the opening piston 607. Then, under the action of the magnetic attraction force, the opening piston 607 moves to the left with the limiting ratchet 608. At the same time, the opening piston 607 squeezes the opening spring 606, the elastic spring 606 shortens and the elastic potential energy increases. Then, the limiting ratchet 608 separates from the anti-reverse ratchet 602. Then, the winding wheel 60... 3 is released, and then the linkage slider 612 moves to the right under the force of the disassembly spring 617, pulling the installation lead wire 609. Then the installation lead wire 609 is released from the outside of the winding wheel 603. Next, the linkage slider 612 moves to the right along with the sliding column 503 through the linkage slider 613. Then the sliding column 503 moves to the right along with the copper socket tube 507 through the radial extension bar 505 and the insulating mounting plate 506. Then the gravity spring 312 applies a rightward pulling force to the moving slider 305 through the gravity line 311. Then the moving slider 305 moves to the right along with the moving column 306. Then the moving column 306 moves to the right along with the supplementary light body 308 through the fixed lamp holder 307, so that the right end face of the moving column 306 is in contact with the insulating mounting plate 503. The surface of 06 remains in contact with the light source. Then, the sliding column 306 and the supplementary light body 308 move into the interior of the replacement chamber 205. Next, the sliding slider 305 is blocked by the limiting ring 304, stopping the sliding column 306 from moving. Then, the sliding column 503, carrying the insulating mounting plate 506 and the copper socket tube 507, continues to move to the right. Then, the right end face of the sliding column 306 separates from the surface of the insulating mounting plate 506. Next, the insertion copper column 309 is pulled out from the inside of the copper socket tube 507, de-energizing the supplementary light body 308. This prevents the supplementary light body 308 from overheating, allowing it to cool down. Afterward, the sliding column 503, carrying the plastic inclined strip 703 and the flipping inclined plate 704, continues to move to the right, blocked by the plastic inclined strip 703. The tilting plate 704 cannot be tilted clockwise. Then, the tilting plate 704 contacts the left side of the energy storage chamfer plate 711 and applies a rightward thrust. Next, the energy storage chamfer plate 711 moves to the right along with the displacement slide 708. Then, under the elastic tension of the energy storage spring 709, the energy storage piston 710 moves downward relative to the displacement slide 708 along with the energy storage chamfer plate 711 and the energy storage support rod 712, ensuring that the energy storage support rod 712 always slides on the bottom surface of the drive main cavity 705. Then, the engagement width between the energy storage chamfer plate 711 and the tilting plate 704 gradually decreases. During this process, the displacement slide 708 pulls the synchronization lead 805. Then, the synchronization lead 805 is released from the outside of the synchronization ring groove 806 and drives the rotating column 804 to rotate.Then, the rotating column 804 rotates the replacement rod 301 through the one-way meshing between the synchronous ratchet head 812 and the synchronous ratchet gear 808. The replacement rod 301 then rotates the facing turntable 41. Next, the inclined surface of the isosceles inclined groove 47 applies a radial thrust to the facing inclined member 45. The facing inclined member 45 then slides slightly into the facing cavity 42, and then slides out of the isosceles inclined groove 47 and onto the inner wall of the facing locking ring 46. Then, the replacement rod 301, through the replacement disc 302, replacement strip 303, sliding slider 305, sliding column 306, and fixed lamp holder 307, rotates the spare supplementary light body 308 upwards. The high-temperature supplementary light body 308 then rotates downwards. After flipping, the engagement width between the flipping ramp 704 and the energy-accumulating chamfer plate 711 is zero. The flipping ramp 704 and the energy-accumulating chamfer plate 711 are then misaligned. The displacement slide 708 no longer moves to the right and is released. At this time, the replacement rod 301 and the facing turntable 41 rotate 180 degrees. The facing ramp 45 is aligned with the isosceles inclined groove 47 again. Then, under the action of the facing spring 43, the facing piston 44 carries the facing ramp 45 into the isosceles inclined groove 47, locking the replacement rod 301. The two supplementary light lamps 308 are now swapped vertically, achieving the purpose of replacing the supplementary light lamps 308. Then, under the action of the torque of the synchronizing spring 803, the synchronizing tube 802 carries the rotating column 804 in the opposite direction. Rotation occurs, at which point there is no transmission between the synchronous ratchet head 812 and the synchronous ratchet gear 808. Then, the synchronous lead wire 805 winds into the synchronous ring groove 806, pulling the displacement slide 708 to the left. Next, the displacement slide 708 moves the energy storage support rod 712 to the left. Then, the bottom surface of the drive main cavity 705 applies an upward thrust to the energy storage support rod 712. Then, the energy storage support rod 712 moves upward along with the energy storage piston 710 and the energy storage chamfer plate 711. Next, the energy storage piston 710 pulls the energy storage spring 709, causing the energy storage spring 709 to stretch elastically and increase its elastic potential energy. Finally, the displacement slide 708 moves to the left within the drive main cavity 705 until it reaches its maximum position. At the designated position, the displacement slide cylinder 708 and the energy storage chamfer plate 711 are reset. Then, the intelligent controller 214 de-energizes the electromagnet 605, thereby limiting the one-way engagement of the ratchet 608 and the anti-reverse ratchet 602. Next, the intelligent controller 214 controls the lamp mounting motor 601 to run, and the sliding column 503 moves to the left under the drive of the lamp mounting motor 601. Then, the flipping ramp 704 contacts the energy storage chamfer plate 711 and reverses upwards. The flipping ramp 704 then passes over the energy storage chamfer plate 711 and flips downwards until it contacts the plastic inclined strip 703. Finally, the sliding column 503 installs the supplementary lighting unit 308 into place according to the above principle.
