Description

Technical Field

[0001] This utility model relates to the field of lighting equipment technology, specifically a multi-scene adaptable studio lighting rapid switching device. Background Technology

[0002] Studio lighting equipment is an indispensable component of modern broadcasting environments. It not only meets basic lighting needs but also plays a crucial role in creating atmosphere, highlighting themes, and enhancing visual effects. A well-designed lighting configuration can effectively improve the expressiveness of broadcast content, providing viewers with a better visual experience. With the diversification of broadcasting needs, the flexible switching of lighting has become particularly important. By quickly switching between different lighting scenes, the studio can rapidly adapt to changes in the themes of different programs. Therefore, developing an efficient lighting switching device can not only improve broadcasting efficiency but also enhance performance effects, allowing lighting to better serve the expression of content.

[0003] Patent CN215372171U discloses an indoor studio wall-mounted lighting device, including a lamp holder frame. A sleeve rod is connected through the top of the lamp holder frame. A slide rod is slidably connected to the inner side wall of the sleeve rod. A slide rail is provided on the outer side wall of the sleeve rod. A traction spring is fixedly connected to the side wall of the slide rail. A fixing block is fixedly connected to the other end of the traction spring. One end of the fixing block is fixedly connected to the outer side wall of the slide rod. A sensor is fixedly connected to the end of the fixing block away from the slide rod. A limit slider is slidably connected to the inner side wall of the fixing block. Three identical locking interfaces are provided on one side of the slide rail. The size of the locking interfaces is the same as the size of the limit slider. A lighting lamp is fixedly connected to the end of the slide rod extending into the inner part of the lamp holder frame. This utility model achieves the adjustment function of the indoor studio wall-mounted lighting through the cooperation of the traction spring, the fixing block, the sensor, and the limit slider.

[0004] The existing technology described above utilizes a drive motor to rotate a threaded rod, causing a drive frame to slide up and down along the outer wall of the light fixture frame, thereby enabling the replacement of different light-transmitting films. However, because the light-transmitting film has multiple color layers arranged sequentially, these layers are exposed one by one as the film moves downwards, resulting in multiple colors of light and making it impossible to quickly switch between single colors. This design limits the flexibility and accuracy of light switching, failing to meet the needs of multi-scene broadcasting. Therefore, to address this deficiency, we propose a multi-scene adaptable studio lighting rapid switching device, aiming to improve the efficiency and accuracy of light switching and better adapt to diverse broadcasting needs.

[0031] Please see Figures 1-5 This utility model provides a technical solution:

[0032] Multi-scene adaptable studio lighting quick switching device, including base 100, combined with Figure 2 , Figure 3 and Figure 5 As shown, a power supply control lamp holder 200 is provided in the middle of the top of the base 100. The wires of the power supply control lamp holder 200 pass through the inner wall of the opaque lamp cover 400 to the outside. The external power supply and controller work. The controller controls the brightness and on / off of the lighting lamp 300, and works with the encoder to control the number of rotations of the motor 620, so that the light-transmitting film 550 can face the light guide tube 700.

[0033] The power supply control lamp holder 200 is equipped with a lighting lamp 300. The lighting lamp 300 acts as a light source and projects light through the light guide tube 700. The top of the base 100 is equipped with an opaque lamp cover 400. The opaque lamp cover 400 is used to encapsulate the internal components and isolate external light interference. The inner wall of the opaque lamp cover 400 is movably connected to a light switching component 500. The light switching component 500 can switch between different colored light-transmitting films 550 by rotation to adapt to scene requirements.

[0034] The lighting switching component 500 includes an internal gear ring 530, which meshes with a gear 630 to transmit driving force. The bottom of the internal gear ring 530 is provided with an annular rotating plate 540, which rotates synchronously with the internal gear ring 530. The outer wall of the annular rotating plate 540 is provided with a plurality of rectangular openings 541 arranged in an annular array. Each of the plurality of rectangular openings 541 is provided with a light-transmitting film 550 of a different color. The light-transmitting film 550 is used to filter the light from the lighting lamp 300 to change the output color.

[0035] The inner wall of the opaque lampshade 400 is provided with a drive assembly 600 for driving the internal gear ring 530 to rotate. The drive assembly 600 drives the light switching assembly 500 to rotate through the motor 620 and the gear 630.

[0036] The outer wall of the opaque lampshade 400 is provided with a light guide tube 700, which is used to directionally project light and transmit the color change of the light-transmitting film 550 to the broadcast area.

[0037] In this embodiment, as Figure 1 As shown, the top of the base 100 has four mounting holes a101 arranged in a matrix, and the base 100 is mounted on the light rack of the studio by bolts.

[0038] The opaque lampshade 400 has a cylindrical structure. The bottom of the outer wall of the opaque lampshade 400 is provided with four mounting plates 410 arranged in a circular array. The top of the mounting plate 410 is provided with mounting holes b411. The mounting plate 410 is installed on the top of the base 100 by bolts.

[0039] Specifically, such as Figure 4 As shown, the lighting switching assembly 500 also includes an annular support plate 510 and an annular limiting plate 520. The outer walls of the annular support plate 510 and the annular limiting plate 520 are fixedly connected to the inner wall of the opaque lampshade 400. The annular support plate 510 and the annular limiting plate 520 are connected to the opaque lampshade 400 by bolts. The top of the annular support plate 510 is in contact with the bottom of the annular rotating plate 540, and the bottom of the annular limiting plate 520 is in contact with the top of the internal gear ring 530. The annular support plate 510 is used to support the annular rotating plate 540 and limit its vertical displacement, and the annular limiting plate 520 is used to constrain the axial movement of the internal gear ring 530.

[0040] Furthermore, such as Figure 3 As shown, the outer wall of the annular rotating plate 540 is attached to the inner wall of the opaque lampshade 400. The attachment design ensures that the annular rotating plate 540 is stable and without deviation when rotating. The length and height of the rectangular opening 541 are both greater than the inner diameter of the light guide tube 700. The size design of the rectangular opening 541 ensures that the light-transmitting film 550 completely covers the light inlet of the light guide tube 700.

[0041] Furthermore, such as Figure 4 As shown, the drive assembly 600 includes a fixed horizontal plate 610 that is bolted to the inner wall of the opaque lampshade 400. A motor 620 is provided on the top of the fixed horizontal plate 610. The motor 620 controls the number of rotations through a controller and an encoder to accurately position the light-transmitting film 550. The output shaft of the motor 620 passes through the top of the fixed horizontal plate 610 and is coaxially connected to a gear 630 that meshes with the internal gear ring 530. The gear 630 meshes with the internal gear ring 530 to transmit rotational power to the light switching assembly 500.

[0042] The outer wall of the annular limiting plate 520 is provided with a clearance opening 521 for avoiding the drive assembly 600. The clearance opening 521 provides space for the meshing area of ​​the gear 630 and the internal gear ring 530 to avoid motion interference.

[0043] Furthermore, such as Figure 1 As shown, a heat sink 800 is provided through the top of the opaque lampshade 400. The heat sink 800 is used to dissipate heat from the inside of the device. The top of the heat sink 800 is provided with multiple heat sink fins 810 arranged at equal intervals. The heat sink fins 810 accelerate heat dissipation by increasing the surface area to ensure the stability of the equipment during long-term operation.

[0044] In this embodiment, the multi-scene adaptable studio lighting quick-switching device is used by the user to fix the base 100 to the studio light frame using bolts through the mounting hole a101. After connecting the external power supply to the power control lamp holder 200, the user adjusts the brightness and on / off status of the lighting lamp 300 through the controller. At the same time, the user selects the preset color mode of the light-transmitting film 550 according to the scene requirements. The controller sends a command to the motor 620 of the drive component 600. The encoder monitors the number of rotations of the motor 620 in real time and feeds back a signal to control the meshing transmission between the gear 630 and the internal gear ring 530, driving the annular rotating plate 540 to rotate until the target light-transmitting film 550 is directly opposite the light guide tube 700. The light inlet is positioned so that the light from the lighting lamp 300 passes through the light-transmitting membrane 550 for filtering and is then directed onto the broadcast area via the light guide tube 700, enabling the switching of a single color light. The annular support plate 510 supports the annular rotating plate 540 to prevent its displacement, the annular limiting plate 520 constrains the axial movement of the internal gear ring 530, and the clearance opening 521 ensures that there is no interference when the gear 630 meshes with the internal gear ring 530. During equipment operation, the heat sink 800 and heat sink fins 810 continuously dissipate the heat generated by the lighting lamp 300 and the motor 620, maintaining a stable internal temperature. Through the above operations, users can quickly complete the switching of lights in multiple scenes to meet different broadcast needs.
