Description

Technical Field

[0001] This invention relates to the field of lighting fixtures and their control technology, specifically to a lighting fixture and its control system that can rotate 360 ​​degrees horizontally. Background Technology

[0002] With the rapid development of modern lighting technology and the continuous expansion of intelligent scenarios, people have placed higher demands on the functionality, adaptability, and ease of operation of lighting fixtures. In many applications, such as commercial displays, stage lighting, architectural floodlighting, home accent lighting, and industrial task lighting, lighting fixtures not only need to provide high-quality and comfortable light, but also often require flexible and precise adjustment of their illumination direction to achieve dynamic lighting effects, track lighting targets, or adapt to changes in layout. Therefore, lighting fixtures with horizontal rotation capabilities have emerged as one of the key devices to meet these needs.

[0003] Currently, luminaires capable of horizontal rotation on the market primarily rely on two technological approaches: one is external mechanical adjustment, which involves manually loosening and tightening fasteners to adjust the luminaire's angle and then re-tightening them. This method is cumbersome, cannot achieve rapid and precise repeatable positioning, and is difficult to integrate into automated lighting systems. The other approach uses a built-in simple rotating mechanism, often employing a shaft and bearing combination. While this type of structure achieves a certain degree of rotation, it is prone to problems such as uneven rotation, jamming, play, or inaccurate angle positioning during long-term use. Especially for luminaires requiring 360-degree omnidirectional rotation without blind spots, existing structures often struggle to balance smooth rotation, self-locking stability at any position, and a compact spatial layout. Furthermore, friction between rotating components can generate noise and lead to wear, affecting service life.

[0004] In terms of lighting quality, traditional rotating luminaires often focus on mechanical structure while neglecting synchronous optical optimization. For example, when adjusting the angle, the light may shine directly into the eyes, causing glare, or the shape and brightness distribution of the light spot may change, affecting the uniformity and comfort of the lighting effect. At the same time, integrating a movable structure presents greater challenges to the luminaire's heat dissipation design. If the heat generated by the light source cannot be dissipated in time, it will accelerate light decay and shorten the luminaire's lifespan; the presence of the rotating part complicates the design of traditional fixed heat dissipation paths.

[0005] With the widespread adoption of the Internet of Things (IoT) and smart homes / buildings, intelligent control of lighting fixtures has become an inevitable trend. Users expect to remotely and conveniently control the on / off state, brightness, and color temperature of lighting fixtures via remote control, mobile app, voice commands, or scene panels, while simultaneously precisely controlling their horizontal rotation to preset or arbitrary angles. Currently, no solutions have been proposed to address these technical challenges. Summary of the Invention

[0006] To address the problems in related technologies, this invention proposes a 360-degree horizontally rotating lamp and its control system to overcome the aforementioned technical issues in existing technologies. The purpose of this invention is to achieve 360-degree horizontal rotation of the lamp, increasing the heat dissipation area. Through contact and convection with air, the heat generated during lamp operation can be efficiently conducted and dissipated, effectively reducing the temperature rise of the lamp and internal components, ensuring stable luminous efficacy, facilitating maintenance and cleaning, improving ease of use, and providing good anti-glare effect. Simultaneously, the rotation angle can be monitored in real time, providing remote control to meet different usage needs and extend the lamp's lifespan.

[0011] Preferably, the cover plate and the hemispherical plate are detachably connected.

[0012] To achieve the above objectives, the present invention also provides the following technical solution: a control system for a lamp capable of 360-degree horizontal rotation, comprising: The main control module is used to receive and process external control commands; The position detection module is used to detect the current rotation angle of the lamp and send the angle information to the main control module; The lighting control module is electrically connected to the main control module and is used to control the switching, brightness and color temperature of the light source according to control commands. A power module is used to supply power to electrical components; The storage module is used to store preset lighting scene modes and corresponding rotation angle parameters; The human-computer interaction module includes at least one of physical buttons, a touch screen, and a voice recognition unit, and is used to receive control commands input by the user.

[0013] Preferably, the position detection module includes an angle sensor and an encoder, which are mounted at the rotatable connection between the support plate and the base.

[0014] Preferably, it also includes a wireless communication module, which is connected to the main control module and is used to receive control signals from the remote control terminal to realize remote control of the lamp.

[0015] Preferably, the wireless communication module supports at least one of Wi-Fi, Bluetooth, Zigbee, and infrared communication protocols.

[0016] Preferably, the main control module includes a microcontroller and a programmable logic controller, and the lighting control module includes a dimming drive circuit.

[0017] Compared with the prior art, the beneficial effects of the present invention are: (1) The present invention is a lamp that can rotate horizontally by 360 degrees and its control system. By setting a steel ball and an annular sliding groove on the support plate, the base and the support plate are movably connected. By setting a support ring and a steel ball on the support plate, the support plate and the protective shell are movably connected. The rotation resistance is significantly reduced, making the rotation operation of the lamp smoother and less labor-intensive. It can also be flexibly stopped at any horizontal angle to achieve lighting without dead angles. The limiting plates on both sides of the protective shell can efficiently install the protective shell into the required position. (2) The present invention is a lamp that can rotate horizontally in 360 degrees and its control system. A support column with several heat dissipation fins is set at the bottom of the hemispherical plate that carries the lamp source, which greatly increases the heat dissipation area. Through contact and convection with the air, the heat generated when the lamp source is working can be efficiently discharged and dissipated, effectively reducing the temperature rise of the lamp source and internal components, thereby ensuring stable light efficiency and significantly extending the overall service life and reliability of the lamp. (3) The present invention is a lamp that can rotate horizontally by 360 degrees and its control system. By setting anti-glare prisms, the distribution of light can be effectively controlled, direct glare can be eliminated, visual comfort can be improved, and the light can be made softer and more uniform. It is suitable for occasions with high requirements for light quality. The cover plate and the hemispherical plate adopt a detachable connection design, so that users or maintenance personnel can easily open the cover plate without disassembling the entire lamp and quickly replace and repair the internal light source, simplifying the daily maintenance and parts replacement process and reducing maintenance costs and time. (4) The present invention is a lamp that can rotate horizontally by 360 degrees and its control system. The rotation angle is monitored in real time by the position detection module and forms a closed-loop feedback system with the main control module, so that the lamp can move precisely and stop at any specified angle. By setting a storage module, preset usage modes can be saved and recalled to improve the ease of use. By setting a human-computer interaction module, it can adapt to different user preferences and usage scenarios. By setting a wireless communication module, users can remotely control the lamp through a mobile APP, remote control or smart home platform to improve the convenience and intelligence of management. (5) The present invention is a lamp that can rotate horizontally by 360 degrees and its control system.

[0020] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Example 1

[0021] Please see Figure 1-5The present invention proposes a technical solution for a 360-degree horizontally rotatable lamp and its control system: A 360-degree horizontally rotatable lamp includes a protective shell 1, a base 3 is provided at the bottom of the inner part of the protective shell 1, a support plate 4 is provided at the top of the base 3, an annular sliding groove 5 is provided at the bottom of the support plate 4, a steel ball 6 is provided inside the annular sliding groove 5, a hemispherical plate 7 is provided inside the support plate 4, a light source 8 is provided inside the hemispherical plate 7, a cover plate 9 is provided at the top of the light source 8, and an anti-glare prism sheet 10 is provided at the top of the hemispherical plate 7.

[0022] In this embodiment, the base and support plate are movably connected by setting steel ball 6 and annular sliding groove 5, which significantly reduces rotational resistance, making the rotation operation of the lamp smoother and less labor-intensive, and allowing it to stop flexibly at any horizontal angle, achieving blind-angle lighting; the anti-glare prism lens 10 can effectively control the distribution of light, reduce or eliminate direct glare, improve visual comfort, and make the light softer and more uniform, suitable for occasions with high light quality requirements; the protective shell 1, base 3, support plate 4, annular sliding groove 5 and steel ball 6 together constitute a stable support and rotation system, ensuring the structural rigidity and stability of the lamp during long-term rotational use, and preventing the rotation function and lighting accuracy from being affected by loosening or deformation.

[0023] Please see Figure 3-4 As shown, furthermore, support rings 11 are installed around the support plate 4, and steel balls 12 are provided on the support rings 11.

[0024] In this embodiment, by setting a support ring 11 and a steel ball 12 on the support plate 4, the support plate 4 and the protective shell 4 are movably connected, thereby further improving the stability of the horizontal rotation of the support plate 4.

[0025] Please see Figure 1 As shown, furthermore, both sides of the protective shell 1 are provided with limit plates 2, and the limit plates 2 are provided with mounting holes.

[0026] In this embodiment, the limiting plates on both sides of the protective shell 1 can efficiently install the protective shell into the required position, improving the ease of installation.

[0027] Please see Figure 1-3 As shown, further, a support column 13 is provided at the bottom of the hemispherical plate 7, and several heat dissipation fins 14 are provided on the support column 13. The heat dissipation fins 14 are made of metal thermally conductive material.

[0028] In this embodiment, the heat dissipation area is greatly increased. Through contact and convection with the air, the heat generated when the lamp source 8 is working can be efficiently conducted out and dissipated, effectively reducing the temperature rise of the lamp source 8 and its internal components, thereby ensuring stable luminous efficacy and significantly extending the overall service life and reliability of the lamp.

[0029] Please see Figure 1 As shown, the cover plate 9 and the hemispherical plate 7 are further detachably connected.

[0030] In this embodiment, the cover plate 9 and the hemispherical plate 7 can be connected by existing snap-fit ​​mechanisms, allowing users or maintenance personnel to easily open the cover plate 9 without disassembling the entire lamp, and quickly replace or repair the internal light source 8, thereby reducing maintenance costs and time.

[0031] Working principle: The core rotational function of the luminaire is achieved by the protective housing 1, base 3, support plate 4, annular sliding groove 5, and steel balls 6. The support plate 4, through its annular sliding groove 5 at its bottom, forms a low-friction rotating pair with the steel balls 6 distributed on the base 3. When the illumination direction needs adjustment, a horizontal force is applied to the lighting part of the luminaire (i.e., the hemispherical plate 7), and this force is transmitted to the steel balls 6 through the support plate 4. The steel balls 6 roll within the annular sliding groove 5, thereby converting sliding friction into rolling friction, greatly reducing rotational resistance. This allows the support plate 4, along with all its components, to rotate smoothly and effortlessly 360 degrees horizontally relative to the fixed base 3 and protective housing 1, and to be precisely positioned at any angle. The steel balls 12 on the support ring 11 contact the inner wall of the protective housing 1, providing auxiliary radial support, further enhancing the smoothness of the rotation process and the stability of the overall structure, preventing wobbling. The limiting plate 2 ensures the reliable fixation of the protective housing 1 to the external mounting structure, providing a stable foundation for the internal rotational movement.

[0032] When the light source 8 is powered on, it emits light, which passes upward through the anti-glare prism lens 10. The anti-glare prism lens 10 redistributes and adjusts the light, reducing direct glare and creating a soft, uniform lighting effect. The heat generated by the light source 8 is mainly conducted through the support column below it. Multiple heat dissipation fins 14 on the support column 13 greatly increase the surface area in contact with the air. The air carries away the heat from the heat dissipation fins 14 through convection (natural convection or with the help of ambient airflow), thus forming an efficient heat dissipation path from the core of the light source 8 to the external environment. This active heat dissipation design ensures that the lamp 8 and the driving circuit operate within a suitable temperature range, guaranteeing the stability of light output and the lifespan of the lamp.

[0033] When it is necessary to replace the light source 8 or clean the optical components, the cover plate 9 can be opened without tools or with simple tools using the detachable connection (such as a snap-fit) between the cover plate 9 and the hemispherical plate 7, allowing direct access to the internal light source 8. This modular design makes core maintenance operations quick and easy, without disassembling the entire luminaire, significantly reducing maintenance complexity and time costs. Example 2

[0034] Please see Figure 1-5 This invention proposes a technical solution for a 360-degree horizontally rotatable lamp and its control system: A control system for a luminaire capable of 360-degree horizontal rotation includes: The main control module is used to receive and process external control commands; The position detection module is used to detect the current rotation angle of the lamp and send the angle information to the main control module; The lighting control module is electrically connected to the main control module and is used to control the switching, brightness and color temperature of the light source 8 according to the control commands. A power module is used to supply power to electrical components; The storage module is used to store preset lighting scene modes and corresponding rotation angle parameters; The human-computer interaction module includes at least one of physical buttons, a touch screen, and a voice recognition unit, and is used to receive control commands input by the user.

[0035] Please see Figure 5 As shown, the position detection module further includes an angle sensor and an encoder, which are mounted at the rotatable connection between the support plate 4 and the base 3.

[0036] Please see Figure 5 As shown, it further includes a wireless communication module, which is connected to the main control module and is used to receive control signals from the remote control terminal to realize remote control of the lamps.

[0037] Furthermore, the wireless communication module supports at least one of the following communication protocols: Wi-Fi, Bluetooth, Zigbee, and infrared.

[0038] Please see Figure 5 As shown, the overall control module further includes a microcontroller and a programmable logic controller, and the lighting control module includes a dimming drive circuit.

[0039] In this embodiment, the user sends a control command containing the target angle and / or lighting parameters through a local interactive interface or a remote wireless signal. The main control module receives and parses the command. If angle adjustment is involved, it calls the current angle feedback value. The main control module calculates the difference between the target angle and the current angle, generates a control signal to drive (such as a motor) to adjust the horizontal angle of the lamp. The position detection module monitors the rotation process in real time and continuously feeds back the accurate angle information to the main control module. The main control module continuously adjusts the output according to the feedback until the lamp rotates to the target angle and the error approaches zero. Simultaneously or independently, the lighting control module adjusts the electrical parameters of the light source according to the command to achieve the expected lighting effect. The user can save the satisfactory angle-light combination as a scene to the storage module for later one-click recall.

[0040] Working principle: Upon power-up, the power module provides stable power to all electronic components. The main control module (microcontroller / PLC) starts up, reading system parameters (such as calibration data and limit angles) and user-preset lighting scenes from the storage module. The position detection module (angle sensor / encoder) measures and reports the current absolute angle of the lighting fixture in real time, and the system enters standby mode, awaiting control commands.

[0041] Users can issue commands in any of the following ways: Local interaction: Operate the physical buttons or touch screen of the human-computer interaction module or give commands via voice (such as "rotate to 90 degrees, adjust the brightness to the brightest").

[0042] Remote control: Control signals are sent to the main control module via a mobile app, remote control, or other terminal through a wireless communication module (Wi-Fi / Bluetooth / Zigbee / Infrared).

[0043] The instructions typically include two core parameters: the target rotation angle and the target lighting status (on / off, brightness, color temperature).

[0044] After receiving the instruction, the main control module enters the core control loop: Command parsing and target setting: The module parses commands to clarify the final target angle value and target light parameters to be achieved.

[0045] Closed-loop control of rotational motion (if angle adjustment is required): Angle acquisition and comparison: The main control module continuously reads the current angle value fed back by the position detection module and calculates it with the target angle value to obtain the angle deviation and the rate of change of deviation.

[0046] Control quantity calculation: The main control module runs the built-in control algorithm (such as PID algorithm) to calculate the precise motor control signal (such as PWM duty cycle and direction) in real time based on the angle deviation.

[0047] Drive execution: The control signal is sent to the rotary drive mechanism (such as the driver of a stepper / servo motor), which drives the motor to rotate, thereby causing the support plate 4 and the lamp body above to start rotating.

[0048] Real-time feedback and adjustment: During rotation, the position detection module continuously samples and provides feedback on the angle at a high frequency. The main control module dynamically adjusts the control signal based on the real-time feedback, ensuring a smooth and rapid rotation process, and ultimately stopping precisely at the target angle with minimal error.

[0049] Synchronous / independent control of lighting output: The main control module sends commands to the lighting control module simultaneously with or independently of the rotation control.

[0050] The dimming drive circuit in the lighting control module, according to instructions, precisely controls the conduction, brightness level, and color temperature ratio of the light source 8 by adjusting the output current or using PWM technology, thereby achieving stepless and smooth changes in optical parameters.

[0051] When a user command invokes a preset scene (such as "reading mode"), the main control module directly reads the angle and lighting parameters stored for that scene from the storage module. Then, it simultaneously executes the aforementioned rotation closed-loop control and lighting control, reproducing complex lighting states in one step. Users can name and save their preferred angle and lighting combination to the storage module through the human-computer interaction interface, creating a personalized scene.

[0052] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
