Currently, intelligent lighting systems are widely used in commercial and industrial applications, but they also have certain limitations: such as significant electromagnetic interference, failing to meet user needs; requiring manual troubleshooting when problems are detected, resulting in low efficiency; and numerous intermediate nodes leading to slow response and poor stability. With the development of intelligent lighting technology, the demand for more efficient, intelligent, and reliable lighting systems is increasing daily. Utility Model Content

[0003] The present invention aims to address the problems of existing intelligent lighting systems, such as high electromagnetic interference, low efficiency due to reliance on manual troubleshooting, and slow response and poor stability due to numerous intermediate nodes. It provides an intelligent lighting system based on SSPC.

[0004] To solve the above problems, this utility model is achieved through the following technical solution:

[0005] An intelligent lighting system based on SSPC consists of an AC / DC module, a primary power distribution switch, at least one secondary SSPC module, and a lighting management center. The number of secondary SSPC modules is the same as the number of lighting zones, with each secondary SSPC module corresponding to one lighting zone. Each secondary SSPC module includes a voltage sensor, at least one drive circuit, at least one solid-state switch, at least one current sensor, at least one conditioning circuit, a microcontroller, and a communication module. The number of drive circuits, solid-state switches, current sensors, and conditioning circuits is the same as the number of lighting loads in the corresponding lighting zone, with each drive circuit, solid-state switch, current sensor, and conditioning circuit corresponding to one lighting load in the lighting zone. The input terminals of all solid-state switches and the voltage sensor together form the input terminal of the secondary SSPC module, and the output terminal of each solid-state switch, after passing through a current sensor, forms the output terminal of the secondary SSPC module. The signal output terminal of the voltage sensor is connected to a signal input terminal of the microcontroller. Each drive output terminal of the microcontroller is connected to the input terminal of a drive circuit, and the output terminal of each drive circuit is connected to the drive terminal of a solid-state switch. The signal output terminal of each current sensor is connected to the input terminal of a conditioning circuit, and the output terminal of each conditioning circuit is connected to a signal input terminal of the microcontroller. The communication terminal of the microcontroller is connected to one end of the communication module, and the other end of the communication module forms the communication terminal of the secondary SSPC module. The AC / DC module's input is connected to the mains power network. The AC / DC module's output is connected to the primary power distribution switch's input. The primary power distribution switch's output is connected to the input of all secondary SSPC modules. The secondary SSPC modules' outputs are connected to the corresponding lighting loads in their respective lighting zones. The secondary SSPC modules' communication terminals are connected to the lighting management center.

[0006] In the above scheme, each secondary SSPC module also includes a temperature sensor, and the signal output terminal of the temperature sensor is connected to a signal input terminal of the microcontroller.

[0007] In the above scheme, each secondary SSPC module also includes a photosensitive sensor, and the signal output terminal of the photosensitive sensor is connected to a signal input terminal of the microcontroller.

[0008] In the above scheme, the output terminal of the AC / DC module is connected to the input terminal of the primary power distribution switch through the primary power bus, and the output terminal of the primary power distribution switch is connected to the input terminals of all secondary SSPC modules through the secondary power bus.

[0010] Compared with existing technologies, this utility model relies on the SSPC (Solid State Power Controller) module as its core. Through the sensing, control, and communication capabilities of the SSPC module, combined with the global collaboration of the lighting management center, it constructs a comprehensive management system encompassing mains power access, power conversion and distribution, intelligent control, and lighting load driving. Through a hierarchical power distribution network (primary power distribution switch + secondary SSPC module power distribution), multi-dimensional sensing and monitoring (electrical parameters such as voltage and current, environmental parameters such as light sensitivity and temperature), and the lighting management center, it achieves precise power supply, intelligent regulation, fault self-diagnosis, and remote operation and maintenance of the lighting system. This solves the problems of high manual dependence, slow response, and poor stability in existing lighting systems, and is suitable for lighting needs in various scenarios such as commercial buildings, industrial plants, and public facilities.

[0013] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific examples and accompanying drawings.

[0014] See Figure 1An intelligent lighting system based on SSPC (Secure Surface Mount Technology) consists of AC / DC modules, a primary power distribution switch, at least one secondary SSPC module, and a lighting management center. The mains power network is connected to the input terminals of the AC / DC modules. The output terminals of the AC / DC modules are connected to the input terminals of the primary power distribution switch via a primary power bus. The output terminals of the primary power distribution switch are connected to the input terminals of all secondary SSPC modules via a secondary power bus. The output terminals of the secondary SSPC modules are connected to the corresponding lighting loads in their respective lighting areas. The mains power network serves as the power input source for the entire system. The AC / DC modules convert the mains power into a power form suitable for subsequent equipment, with the power output determined based on the overall system load. The AC / DC conversion must be compatible with the system's rated voltage (such as a common 48V / 24V DC bus) to ensure the DC power supply needs of subsequent modules. The power after AC / DC conversion is fed into the primary power distribution switch for initial power distribution. The primary distribution switch, as the system's main controller, forms the foundation for a stable and safe DC bus. It integrates short-circuit and overload protection functions, enabling power supply switching, overload / short-circuit protection (configurable with fuses or smart circuit breakers), and rapid disconnection of the primary bus in case of a fault to prevent fault propagation. This provides fault protection during initial power distribution, enhances primary power distribution safety, and enables system-level power supply control. The power initially distributed by the primary distribution switch is then sent to the secondary SSPC module for intelligent control processing. The secondary SSPC module supplies the processed power to the lighting loads in the lighting area, providing lighting functionality. The secondary SSPC module integrates control, protection, sensing, and compensation functions, employs contactless solid-state switches, supports multiple load outputs, and adapts to different load numbers and distributions through a modular architecture. Leveraging the fast response characteristics of solid-state switches, it reduces electromagnetic interference and simultaneously improves power distribution response speed and operational stability. The lighting loads, as the terminals of the intelligent lighting system, convert electrical energy into light energy, providing illumination to various areas. The lighting loads support intelligent switching and brightness adjustment to meet different scenario requirements and possess fault isolation characteristics, ensuring that a single load failure does not affect the entire system.

[0015] The number of secondary SSPC modules is the same as the number of lighting zones, with each secondary SSPC module corresponding to one lighting zone. See also Figure 2Each secondary SSPC module includes a voltage sensor, a photosensor, a temperature sensor, at least one driver circuit, at least one solid-state switch, at least one current sensor, at least one conditioning circuit, a microcontroller, and a communication module. The number of driver circuits, solid-state switches, current sensors, and conditioning circuits is the same as the number of lighting loads in the corresponding lighting area. Each driver circuit, solid-state switch, current sensor, and conditioning circuit corresponds to one lighting load in the lighting area. The input terminals of all solid-state switches and the voltage sensor together form the input terminal of the secondary SSPC module, meaning the secondary SSPC module has one input terminal. The output terminal of each solid-state switch, after passing through a current sensor, forms the output terminal of the secondary SSPC module, meaning the secondary SSPC module has the same number of input terminals as the number of lighting loads in the corresponding lighting area. The signal output terminals of the voltage sensor, photosensor, and temperature sensor are directly connected to the corresponding signal input terminals of the microcontroller. Each driver output terminal of the microcontroller is connected to the input terminal of a driver circuit, and the output terminal of each driver circuit is connected to the driver terminal of a solid-state switch. The signal output terminal of each current sensor is connected to the input terminal of a conditioning circuit, and the output terminal of each conditioning circuit is connected to a signal input terminal of the microcontroller. The communication terminal of the microcontroller is connected to one end of the communication module, and the other end of the communication module forms the communication terminal of the secondary SSPC module.

[0016] The drive circuit receives drive signals from the microcontroller, precisely driving the on / off state of the corresponding solid-state switch to control the load power supply. Replacing traditional mechanical switches with contactless solid-state switches eliminates the risk of contact wear, improves switch response speed, reduces electromagnetic interference, and enhances system electromagnetic compatibility. A current sensor collects the current of the corresponding lighting load, which is processed by the conditioning module before being sent to the microcontroller. A voltage sensor collects the voltage fed into the secondary SSPC module and sends it directly to the microcontroller. A temperature sensor, located within the secondary SSPC module, collects the ambient temperature and sends it directly to the microcontroller. A photosensor, located within the lighting area, collects the ambient light intensity and sends it directly to the microcontroller, allowing the system to dynamically adjust lighting based on the environment, achieving energy savings. The communication module interacts with the external lighting management center, transmitting data and receiving control commands to achieve intelligent module management. The microcontroller, the central hub of the secondary SSPC module, integrates electrical signals, environmental signals, and external commands, interacting with external systems through the communication module to achieve multi-signal fusion control of the solid-state switches. The secondary SSPC module acts as the intelligent power distribution manager in a smart lighting system. It draws power from the secondary power bus and uses solid-state switchgear to precisely control the power distribution output of multiple loads. It senses the status with the help of sensors such as current, voltage, light, and temperature, as well as conditioning circuits. Through drive circuits and microcontrollers, it realizes intelligent decision-making and control. It can also interact with the lighting management center through a communication module to achieve fault self-diagnosis, precise power distribution, intelligent regulation, and remote operation and maintenance, thereby improving the stability, energy efficiency, and intelligence level of the lighting system, making load control precise, status traceable, and fault controllable.

[0017] As the control center of the system, the lighting management center serves two main functions. First, it connects to the communication terminals of each secondary SSPC module via the communication center, enabling communication control and other operations. Second, it establishes connections with the cloud / mobile terminals to achieve remote monitoring, parameter setting, and command issuance, realizing regionalized management and flexible control, improving user convenience for operation and maintenance, and forming a complete intelligent lighting management closed loop. The lighting management center implements functions such as data acquisition, visualization, policy configuration, command issuance, fault location, intelligent alarm, remote handling, data storage, intelligent analysis, energy-saving optimization, and predictive maintenance of energy consumption. This achieves closed-loop management from data acquisition and intelligent decision-making to execution feedback, significantly improving the operational efficiency, stability, and energy efficiency of the lighting system.

[0018] In view of the problem that the existing intelligent lighting system lacks accurate and independent monitoring means for each lighting load circuit and electrical parameters. When lighting anomalies occur, it is impossible to quickly locate whether the problem lies in the mains power conversion, primary power distribution, subsequent power distribution module or the load itself. Manual troubleshooting section by section is required, which is time-consuming and laborious, and it is difficult to quickly restore lighting. The current sensor in the secondary SSPC module of the present utility model can accurately and independently monitor the current of the corresponding load circuit, and the voltage sensor monitors the voltage of the secondary power bus. When lighting anomalies occur, the microcontroller combines the sensing data processed by the conditioning module to quickly locate whether the fault is in the load circuit, bus voltage or module internal problem, eliminating the need for manual troubleshooting section by section, greatly shortening the fault location time, and improving the lighting restoration efficiency.

[0019] In view of the problem that when anomalies such as mains voltage fluctuations and overheating in the power distribution module occur, it is difficult for all links of the existing intelligent lighting system to respond promptly in coordination, unable to quickly cut off the faulty circuit, adjust the power supply or give an alarm, which is likely to expand the scope of the fault impact and reduce the continuous and stable operation ability of the lighting system, and lacking the linkage control based on multi-sensors and the centralized management center. Based on the status information uploaded by each secondary SSPC module, when a certain secondary SSPC module fails, the lighting management center of the present utility model can dispatch other normal secondary SSPC modules through the communication bus to provide coordinated compensation power supply for the lighting area corresponding to the faulty module (such as extended power supply by the secondary SSPC module in the adjacent area), improving the overall fault tolerance of the system, preventing the entire system from being abnormal due to the abnormality of one module, and ensuring lighting continuity.

[0020] In view of the problem that the existing intelligent lighting system cannot automatically and accurately adjust the brightness of the corresponding lighting area according to the ambient light, nor can it perform differential and scenario-based intelligent control on different lighting areas, which can neither meet the energy-saving requirements nor adapt to diverse lighting scenarios. The present utility model adds a photosensitive sensor that can dynamically adjust the light according to the environment to achieve energy conservation and consumption reduction, and supports remote monitoring, parameter setting and instruction issuance through the cloud or mobile terminal to achieve regional management and flexible control.

[0021] In view of the problem that the existing intelligent lighting system cannot provide data support for the global optimization scheduling and preventive maintenance of the system, which is not conducive to the long-term reliable operation of the system. The present utility model realizes real-time and comprehensive data interaction between the mains power conversion, primary power distribution switch, each SSPC module and the lighting management center by means of the communication module of the SSPC module and the communication bus. The lighting management center can timely obtain the operation status information such as the voltage of the primary power bus, the current and temperature in the SSPC module, providing data support for the global optimization scheduling and preventive maintenance of the system, greatly reducing the fault incidence rate after the preventive maintenance of the system, and ensuring the long-term reliable operation of the system.

[0022] In summary, this system, through multi-module collaboration, achieves environmental perception, intelligent dimming, anomaly handling, and remote communication functions. Users can manage and monitor the entire lighting system regionally via the cloud or mobile devices (such as a mobile app), and can also adjust the working mode of the lighting load and detect faults according to actual needs, thereby achieving centralized management and control of the entire lighting power distribution system. Simultaneously, this system supports modular expansion, flexibly adapting to different load scales, improving system scalability and scenario adaptability. Through a cloud-edge collaborative architecture, it reduces manual intervention and automatically executes actions such as fault warnings and dimming strategies, simultaneously improving intelligent power distribution efficiency and precise control capabilities.

Therefore, the present invention is not limited to the specific embodiments described above. Any other embodiments obtained by those skilled in the art under the guidance of the present invention without departing from its principles are considered to be within the protection scope of the present invention.
