Description

Technical Field

[0001] This utility model relates to the field of lighting control technology, and in particular to an RGB light strip intelligent controller. Background Technology

[0002] In the continuous development of lighting technology, RGB light strips and dual-color temperature light strips have become increasingly popular in many scenarios due to their unique lighting effects. However, traditional light strip controllers have significant drawbacks:

[0003] 1. Narrow voltage adaptability: Most traditional controllers can only operate under specific voltages, exhibiting poor compatibility with common 12V and 24V dual-voltage inputs. In practical applications, different LED strips may require different power supplies. For example, some RGB LED strips are compatible with 12V, while some dual-color temperature LED strips require 24V. Traditional controllers cannot flexibly switch between these voltages, limiting the selection of LED strips and their application scenarios.

[0004] 2. Limited LED Strip Type Control: Typically, only one type of LED strip can be controlled, either only for RGB strips or only for dual-color temperature strips. This means that if users need to use multiple types of LED strips simultaneously, they will require multiple controllers, increasing costs, taking up more space, and causing inconvenience in installation and use.

[0005] 3. Lack of intelligent linkage and wide voltage adaptability: Under the trend of smart lighting, traditional controllers are difficult to integrate into the smart home ecosystem and cannot work collaboratively with other smart devices. At the same time, they cannot effectively adapt to wide voltage ranges when faced with grid voltage fluctuations, voltage differences in different regions, and special power supply output voltage variations, resulting in unstable operation of the light strips, affecting lighting effects and equipment lifespan.

[0006] Therefore, this application proposes an RGB LED strip intelligent controller to solve the above problems. Utility Model Content

[0007] The purpose of this invention is to address the technical problems existing in the background art regarding the deficiencies of current LED strip controllers in terms of voltage adaptability and LED strip type compatibility, and to propose an RGB LED strip intelligent controller.

[0008] The technical solution of this utility model is as follows: an RGB light strip intelligent controller, including a wide voltage input circuit module, a core control unit and a wireless radio frequency module. The core control unit is electrically connected to the wide voltage input circuit module and the wireless radio frequency module respectively. The wide voltage input circuit module adopts a Buck-Boost type DC-DC conversion topology structure to integrate the control of RGB light strips and dual color temperature light strips.

[0009] Optionally, the wide voltage input circuit module adopts a Buck-Boost DC-DC conversion topology to monitor the input voltage in the range of 3-60Vdc in real time. When the input voltage fluctuates around 12V or 24V, it selects to output a stable DC voltage of 12V or 24V according to a preset threshold.

[0010] Optionally, the wide voltage input circuit module has built-in overvoltage protection circuit and undervoltage protection circuit to cut off the power supply when the voltage is abnormal.

[0011] Optionally, the wide voltage input circuit module is equipped with a 12V and 24V dual voltage selection output unit, and the user can switch the output voltage by operating the DIP switch.

[0012] Optionally, the wide voltage input circuit module has a wide voltage input range of 3~60Vdc.

[0013] Optionally, the wireless radio frequency module is a 433 wireless radio frequency module with a frequency range of 433.05~434.79MHz.

[0014] Optionally, the wireless radio frequency module interacts with the core control unit via a high-speed SPI interface.

[0015] Optionally, it also includes a MOSFET switching circuit, wherein the core control unit is electrically connected to the MOSFET switching circuit using a PWM signal.

[0016] Compared with the prior art, this application includes at least one of the following beneficial technical effects:

[0017] 1. Wide Voltage Adaptability and Dual Voltage Output: This controller operates stably within a wide voltage input range of 3-60Vdc and can flexibly output 12V or 24V voltage according to user needs, effectively solving the problem of different voltage requirements for different types of LED strips. Whether in areas with unstable voltage standards or when using emergency power supplies, portable power supplies, or other special power sources, it ensures the normal operation of the LED strips, greatly expanding their applicability and improving the versatility and adaptability of lighting systems.

[0018] 2. Integrated Control of Multiple LED Strips: This feature enables integrated control of RGB and dual-color temperature LED strips. Users no longer need separate controllers for different types of LED strips, reducing costs and simplifying installation and usage. A single controller can meet diverse lighting needs. For example, in commercial displays, RGB LED strips can be used simultaneously to create a colorful atmosphere, while dual-color temperature LED strips provide basic lighting, achieving richer and more flexible lighting effects.

[0019] 3. Achieving Intelligent Upgrades in Non-Intelligent Scenarios: In traditional non-intelligent lighting scenarios, the intelligent controller of this invention can easily upgrade ordinary light strips into intelligent lighting devices through simple installation without complex wiring modifications. Users can easily achieve remote control via a mobile app, adjusting the color, brightness, and light and shadow modes of the light strips at will, regardless of their location, to meet diverse lighting needs.

[0030] like Figure 1 As shown, this utility model proposes an intelligent controller for RGB light strips, comprising a wide-voltage input circuit module, a core control unit, and a wireless radio frequency module. The core control unit is electrically connected to both the wide-voltage input circuit module and the wireless radio frequency module. These components work together to achieve intelligent and precise control of RGB light strips and dual-color-temperature light strips, and feature wide-voltage input and multi-light strip selection capabilities. Specifically, the core control unit uses a high-performance ARM architecture MCU with built-in large-capacity Flash memory and high-speed RAM. The microprocessor quickly generates corresponding PWM signals based on received instructions. For RGB light strips, it can precisely adjust the driving current of the red (R), green (G), and blue (B) LEDs to achieve accurate color rendering and brightness adjustment accuracy of 0.1%. For dual-color-temperature light strips, it can precisely control the brightness ratio of warm and cool color temperatures, achieving delicate color temperature adjustment and creating different lighting effects. This intelligent controller for RGB light strips integrates the control of RGB and dual-color-temperature light strips, eliminating the need for separate controllers for different types of light strips, reducing costs, simplifying installation and usage, and meeting diverse lighting needs.

[0031] In this embodiment, it is important to note that the wide voltage input circuit module employs a Buck-Boost DC-DC conversion topology, coupled with a high-precision intelligent voltage detection chip. This module can monitor the input voltage in real time within the range of 3-60Vdc, and features automatic voltage adjustment. The controller operates stably, adapting to different drive power supplies, ensuring the normal operation of RGB and dual-color temperature LED strips, expanding the applicability of the LED strips, and improving the versatility and adaptability of the lighting system. When the input voltage fluctuates around 12V or 24V, it can accurately select a stable 12V or 24V DC output voltage based on a preset threshold to meet the power supply requirements of different LED strips. Simultaneously, it incorporates overvoltage and undervoltage protection circuits; in the event of an abnormal voltage, it immediately cuts off the power supply to ensure the safety of the LED strip and controller components. This module also features a 12V / 24V dual voltage selection output function, allowing users to easily switch the output voltage via a DIP switch to adapt to different types of LED strips without needing to replace the power supply or controller.

[0032] Furthermore, the wireless RF module integrates a 433MHz wireless RF module. The 433MHz band has advantages such as good signal propagation characteristics, strong penetration ability, and good diffraction ability, ensuring stable signal transmission even in complex environments. The 433MHz wireless RF module interacts with the core control unit via a high-speed SPI interface. Users can connect to the system using a compatible smart home gateway to control the light strip's on / off state, color switching, brightness adjustment, and other functions.

[0033] In this embodiment, as Figure 2 As shown, the power supply system circuit mainly consists of a buck-boost chip U2, a DIP switch S1 (for 12V / 24V voltage selection), a buck chip U3, and several surface-mount components. The buck-boost chip U2, forming a BUCK-Boost circuit, adapts to input voltages from 3Vdc to 60Vdc. Based on the voltage switching of the feedback pin of U2 via the DIP switch S1, it precisely outputs 12Vdc or 24Vdc to power the LED strip and U3. The buck chip U3 provides a fixed 3.3V voltage, ensuring power supply to the microcontroller (MCU) and the 433MHz wireless RF module.

[0034] like Figure 3 As shown, the 433MHz wireless RF module communicates with the MCU via SPI communication through communication lines such as MISO, MOSI, NSS, and SCK. This allows the MCU to efficiently control parameters such as the wireless RF module's transmit power and frequency, while simultaneously obtaining rapid feedback, thus improving system response speed and interaction efficiency.

[0035] like Figure 4As shown, the MOSFET switching circuit controls the LED strip: the MCU uses a PWM signal to control the MOSFET switching circuit, precisely controlling the RGB LED strip and the dual-color temperature LED strip respectively. With a wide voltage input circuit module ensuring a stable voltage supply, precise control of the color and brightness of the RGB LED strip and the color temperature of the dual-color temperature LED strip is achieved to meet different lighting needs.

[0036] This application provides a smart controller with a wide voltage input range (3Vdc~60Vdc, 12V / 24V dual voltage selectable output) and integrated multi-channel LED strip controller. It can control RGB LED strips for accurate color rendering and fine brightness adjustment, as well as control dual-color temperature LED strips for flexible color temperature switching. Furthermore, it can be integrated into a smart ecosystem. This controller enables stable and intelligent control of different types of LED strips under complex voltage environments, improving the user's lighting experience and enhancing the compatibility and flexibility of the lighting system. It is widely applicable to diverse scenarios such as home lighting, commercial displays, and stage lighting, meeting users' intelligent control needs for different types of LED strips under complex voltage conditions.

[0037] The above specific embodiments are merely several optional embodiments of this utility model. Based on the technical solution of this utility model and the relevant teachings of the above embodiments, those skilled in the art can make various alternative improvements and combinations to the above specific embodiments.
