Description

Technical Field

[0001] This utility model relates to the field of LED lighting technology, specifically a wirelessly remote-controlled LED follow spot structure. Background Technology

[0002] With the development of LED technology, LED follow spots have been widely used in stage lighting, performances, and sporting events due to their high efficiency, energy saving, and long lifespan. However, traditional LED follow spots typically install various adjustment mechanisms inside the fixture, such as dimming lenses, focusing screws, and adjustment motors, to achieve dimming and focusing functions. These adjustment mechanisms inevitably affect the beam transmission path during operation, easily causing beam scattering or deflection, thereby reducing beam concentration and lighting effect. In addition, the adjustment mechanism of traditional LED follow spots mostly adopts mechanical drive, which may result in low precision and slow response speed, making it impossible to accurately adjust various beam parameters (such as light intensity, light color, and beam angle).

[0003] In modern performances and stage shows, with ever-increasing demands for lighting effects, traditional adjustment methods are no longer sufficient to meet the needs for precise beam control, especially in dynamic follow spotting and remote control. Traditional LED follow spot systems lack sufficient flexibility and stability. Therefore, how to achieve precise dimming and focusing of the beam without interfering with beam transmission has become an important issue in the development of LED follow spot technology.

Detailed Implementation

[0034] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0035] Please see Figure 1-7 A wirelessly remote-controlled LED follow spot structure includes an assembly bracket 1, an assembly cylinder 2, a swing adjustment component, and a pitch adjustment component. The assembly bracket 1 is installed in a manner that rotates around a vertical axis and is poweredly connected to the swing adjustment component. The assembly cylinder 2 is installed on the assembly bracket 1 in a manner that rotates around a horizontal axis. The pitch adjustment component is installed on the assembly bracket 1 and is poweredly connected to the assembly cylinder 2.

[0036] It also includes a light source assembly, a dimming assembly, and a focusing assembly arranged sequentially in the assembly cylinder 2, with the light source assembly facing the dimming assembly and the focusing assembly.

[0037] The dimming assembly includes a rotating disk 61, dimming lenses 62, and an adjustment motor C63 that is powered to the rotating disk 61. The rotating disk 61 is rotatably mounted in the assembly cylinder 2. The axis of the rotating disk 61 is parallel to the light transmission direction of the light source assembly. The dimming lenses 62 are evenly arranged in a ring array on the rotating disk 61.

[0038] The focusing assembly includes a sliding ring seat 71, a focusing lens 72, a mounting sleeve 73, a fixed lens 74, and an adjustment motor D75 that is poweredly connected to the sliding ring seat 71. The sliding ring seat 71 is slidably installed in the assembly cylinder 2, the focusing lens 72 is fixedly installed in the sliding ring seat 71, the mounting sleeve 73 is fixedly installed at the front end of the assembly cylinder 2, and the fixed lens 74 is fixedly installed in the mounting sleeve 73. The dimming lens 62 at the top, the focusing lens 72, and the fixed lens 74 are all arranged on the same axial direction.

[0039] The mounting bracket 1 ensures that the mounting cylinder 2 is mounted on it in a relatively rotating manner, and with the cooperation of the swing adjustment component and the pitch adjustment component, the light source component, dimming component and focusing component set in the mounting cylinder 2 can be synchronously adjusted in angle.

[0040] Specifically, the swing adjustment component can drive the assembly bracket 1 and the assembly cylinder 2 to rotate stably around the vertical axis, so as to adjust the tilt angle of the assembly cylinder 2 swinging left and right. The pitch adjustment component can drive the assembly to adjust the tilt angle. With the cooperation of the swing adjustment component and the pitch adjustment component, the orientation of the assembly can be precisely adjusted to achieve the light-tracking effect.

[0041] In assembly cylinder 2, the light source assembly emits light forward. The adjusting motor C63 in the dimming assembly drives the rotating disk 61 and the dimming lens 62 to rotate, positioning the dimming lens 62 at a specific location on the light transmission path. Each dimming lens 62 has a different function, used to adjust the light beam's color, atomization, and aperture. The adjusting motor D75 in the focusing assembly, while driving the sliding ring seat 71 and the focusing lens 72 to slide, changes the focus of the light beam and, in conjunction with the fixed lens 74, concentrates or diffuses the light beam emitted from the light source assembly, directly affecting the beam's shape and clarity.

[0042] Based on the above technical solution, a remote controller, a receiver, and a control module also need to be installed. The remote controller is used to send control signals to adjust various parameters of the LED follow spot, such as on / off, brightness, color, and mode. The receiver is used to receive signals from the remote controller and convert them into control signals, which are then transmitted to the control module of the LED follow spot. The control module is used to receive and process the control signals from the receiver and adjust the drive or control units of the swing adjustment component, pitch adjustment component, light source component, dimming component, and focus component to achieve the adjustment of various parameters of the LED follow spot.

[0043] The remote control and receiver may use specific communication protocols, such as Zigbee, Bluetooth, Wi-Fi, etc., to ensure the reliability and anti-interference of signal transmission.

[0044] To ensure that the mounting bracket 1 can be stably installed in a relative rotation manner and that the follow spot lamp can be stably installed on site, while ensuring that the swing focusing component drives the transfer bracket to operate stably, the following technical solution is provided.

[0045] It also includes an assembly base 8, a rotating seat 11 fixedly connected to the bottom end of the assembly bracket 1 and rotatably mounted on the assembly base 8, and an assembly opening 81 opened on the edge of the assembly base 8.

[0046] The mounting base 8 and the rotating seat 11 cooperate to enable the mounting bracket 1 to be stably installed in a relative rotation manner, while the mounting port 81 can be used to stably install the mounting base 8 through the bolt assembly, thereby ensuring the stable installation of the LED follow spot.

[0047] The swing adjustment assembly includes an adjustment motor A31, a drive bevel gear A32, and a transmission bevel gear A33. The adjustment motor A31 is fixedly mounted on the mounting base 8, the drive bevel gear A32 is fixedly connected to the output shaft of the adjustment motor A31, and the transmission bevel gear A33 is fixedly connected to the rotating seat 11 and meshes with the drive bevel gear A32.

[0048] When the swing adjustment component is in operation and the swing angle of the assembly bracket 1 is adjusted, the adjustment motor A31 drives the drive bevel gear A32 to rotate, which in turn drives the transmission bevel gear A33, the rotating seat 11, and the assembly bracket 1 to rotate stably around the vertical axis where the rotating seat 11 is located.

[0049] To ensure that the pitch adjustment assembly and the assembly cylinder 2 can be stably installed on the assembly bracket 1, and that the pitch adjustment assembly can adjust the pitch angle of the assembly cylinder, the following technical solution is provided.

[0050] Two sets of coaxially arranged assembly pins 21 are fixedly connected to the outer wall of the assembly cylinder 2 and are rotatably connected to the assembly bracket 1. An assembly cover 12 is fixedly installed on the assembly bracket 1 and sleeved around the pitch adjustment component.

[0051] The mounting pin 21 ensures that the mounting cylinder 2 is stably installed on the mounting bracket 1 in a relatively rotating manner, while the mounting cover 12 ensures that the pitch adjustment component is stably installed inside it and achieves a power connection with the mounting pin 21.

[0052] The pitch adjustment assembly includes an adjustment motor B41, a worm gear A42, and a worm A43. The adjustment motor B41 is fixedly mounted on the mounting bracket 1 and is poweredly connected to the worm A43. The worm A43 is rotatably mounted on the mounting bracket 1 and maintains a connection with the worm gear. The worm gear A42 is fixedly connected to one of the sets of mounting pins 21.

[0053] When the pitch adjustment assembly is running, the adjustment motor B41 drives the worm gear A43 to operate stably, which in turn drives the worm wheel A42, the assembly pin 21, and the assembly cylinder 2 to operate stably. The assembly pin 21 is arranged in the horizontal direction, and the combination of the worm wheel A42 and the worm gear A43 has the characteristics of speed reduction and torque increase and one-way self-locking, which can drive the assembly cylinder 2 to operate stably around the assembly pin 21. When the adjustment motor B41 is stopped, it can ensure that the assembly cylinder 2 is at a specific pitch angle without invalid rotation.

[0054] To ensure that the light source assembly can be stably installed and operated in the assembly cylinder 2, the following technical solution is provided.

[0055] The light source assembly includes a circuit board 51, LED beads 52, a condenser cup 53, and a heat sink 54. The condenser cup 53 is fixedly installed at the rear port of the assembly cylinder 2. The circuit board 51 is fixedly installed in the condenser cup 53. The LED beads 52 are evenly arranged on the circuit board 51 and in the condenser cup 53. The heat sink 54 is fixedly installed on the assembly cylinder 2 and arranged around the circuit board 51.

[0056] The circuit board 51 provides a stable power supply to the LED beads 52 and ensures their normal operation. The light emitted by the LED beads 52 is focused by the condenser cup 53 so that the light emitted by the light source assembly is in a beam directed towards the dimming and focusing components. The heat sink 54 has heat dissipation holes to allow free entry and exit of external air for continuous heat dissipation of the circuit board 51.

[0057] To ensure that the dimming component can be stably installed in the assembly cylinder 2 and to avoid interference with the beam transmission, and to ensure that the adjustment motor C63 can drive the rotating disk 61 to operate stably, the following technical solutions are provided.

[0058] The bottom of the assembly cylinder 2 is provided with an assembly groove 22. The rotating disk 61 is arranged in the assembly groove 22. The dimming assembly also includes a drive bevel gear B64, a transmission bevel gear B65, and a matching combination worm gear B66 and worm B67 arranged in the assembly groove 22. The transmission bevel gear B65 is fixed to the axis of the rotating disk 61 and meshes with the drive bevel gear B64. The drive bevel gear B64 and the worm gear B66 are coaxially fixed and rotatably installed in the assembly groove 22. The worm B67 is rotatably installed in the assembly groove 22 and is poweredly connected to the output shaft of the adjusting motor C63.

[0059] The assembly slot 22 ensures that the rotating disk 61 is stably installed in the assembly cylinder 2 in a relatively rotating manner, and ensures that the components installed therein leave the beam transmission path clear.

[0060] When the adjusting motor C63 drives the worm gear B67 to rotate, it can drive the worm wheel B66 and the drive bevel gear B64 to operate stably, which in turn drives the transmission bevel gear B65 and the rotating disk 61 to operate stably. Since the combination of the worm wheel B66 and the worm gear B67 has the characteristics of speed reduction and torque increase and one-way self-locking, it can drive the rotating disk 61 to operate stably. After the rotating disk 61 is adjusted, it is locked and positioned to ensure that the light beam can pass through the specific dimming lens 62 and be further transmitted to the adjusting component.

[0061] To ensure that the focusing assembly can be stably installed in the assembly cylinder 2 and to avoid interference with the beam transmission, and to ensure that the adjusting motor D75 can drive the sliding ring seat 71 to slide stably, the following technical solution is provided.

[0062] The focusing assembly also includes adjusting screws 76 and synchronous pulleys 77 that are rotatably mounted inside the assembly cylinder 2 and maintain a circular array distribution. Some of the synchronous pulleys 77 are fixedly connected to the coaxially arranged adjusting screws 76, and each group of synchronous pulleys 77 is powered by a synchronous belt 771. Each group of adjusting screws 76 is screwed to the sliding ring seat 71.

[0063] The focusing assembly also includes a drive bevel gear C78 and a transmission bevel gear C79. The adjusting motor D75 is arranged in the assembly slot 22 and is poweredly connected to the drive bevel gear C78. A set of synchronous pulleys 77 has a transmission bevel gear C79 fixed at its shaft center, which meshes with the drive bevel gear C78.

[0064] A guide rail 23 is fixed to the inner wall of the assembly cylinder 2, and a guide groove 711 adapted to the guide rail 23 is opened on the outer wall of the sliding ring seat 71. Each synchronous wheel 77 and adjusting screw 76 are set close to the inner wall of the assembly cylinder 2 to avoid affecting the normal transmission of the beam. When the adjusting motor D75 drives the drive bevel gear C78 to run, it can drive the transmission bevel gear C79 and each set of synchronous wheels 77 and adjusting screw 76 to run synchronously. The adjusting screw 76 can drive the sliding ring seat 71 to slide stably in the assembly cylinder 2.
