DETAILED DESCRIPTION
[0018] Exemplary embodiments of the present disclosure will be described below in greater detail with reference to the accompanying drawings. Although exemplary embodiments of the present disclosure are shown in the drawings, it is to be understood that the present disclosure can be implemented in various forms and should not be limited by the embodiments set forth herein.

It should be noted that the embodiments in the present application and the features in the embodiments can be combined with each other without conflict. The present application will be described in detail below with reference to the accompanying drawings and in conjunction with the embodiments.
[0019] As shown in Figures 1-2 In some embodiments of the present application, the present embodiment provides a lighting system of a combined luminaire, comprising: a light source module, a heat dissipation shell, a temperature regulation module, a control module, an adaptive adjustment module, a display module, a communication module, and a fault detection module.
[0020] Specifically, the light source module is provided with a plurality of independent light source units, and each independent light source unit contains one or more LED chips, the LED chips are fixedly connected with an aluminum substrate through a heat-conducting silica gel layer, and the aluminum substrate is installed on the heat dissipation shell through bolts; the heat dissipation shell is internally provided with a plurality of parallel heat-conducting fins, and a micro fan is arranged between the heat-conducting fins to enhance air flow; the temperature regulation module is provided with a plurality of temperature sensors and a thermoelectric cooling fin located in the central region of the heat dissipation shell, wherein the temperature sensors are arranged at different positions of the light source module to monitor the temperature distribution, and the thermoelectric cooling fin is tightly attached to the heat dissipation shell through a heat-conducting pad; the control module is connected with the light source module, the temperature regulation module, and an external intelligent terminal, respectively, to analyze the temperature field distribution characteristics of the light source module based on the data collected by the temperature sensors, and to adjust the brightness output and color temperature parameters of the light source module according to the temperature field distribution characteristics; the adaptive adjustment module is provided with a light-sensitive sensor and an ambient light analysis unit to monitor the ambient light intensity in real time and adjust the output power of the light source module based on the change of the ambient light intensity; the display module is connected with the control module to display the running state and temperature distribution data of the light source module.
[0021] Specifically, the communication module is connected with the control module, for transmitting the operation state data and the temperature distribution data of the light source module to an external intelligent terminal; wherein the communication module sends the data packet to the gateway device after packing by Zigbee protocol, and the gateway device forwards the data to the external intelligent terminal by Wi-Fi protocol.
[0022] Specifically, the fault detection module is connected with the control module, for monitoring the operation state of the light source module and judging whether there is a potential fault risk based on the temperature field distribution characteristics and the light adjustment parameters; wherein if there is a potential fault risk, the fault detection module generates a fault warning information and sends it to the external intelligent terminal through the communication module.
[0023] It can be understood that the light source module adopts the structural design of LED chip combined with aluminum substrate and heat-conducting silicone layer, so that the heat generated by the chip can be quickly conducted to the heat dissipation shell. The heat-conducting fins and micro fans inside the heat dissipation shell further promote air convection, and the combination of passive and active heat dissipation is achieved by enhancing heat exchange. This heat-conduction-convection composite principle effectively avoids the problem of local overheating of the LED chip, thereby ensuring the stability of the light source output. Secondly, the temperature regulation module relies on distributed temperature sensors to realize real-time monitoring of the temperature field, and combines the Peltier effect of the thermoelectric refrigeration piece to actively control the temperature. When the sensor detects a local temperature rise, the thermoelectric refrigeration piece converts the temperature difference between the hot and cold ends through current driving to export excess heat to the heat dissipation shell. This combination of passive heat dissipation and active thermoelectric refrigeration ensures that the light source maintains an appropriate temperature range under different working conditions. The control module is the core of the entire system, which adjusts the brightness and color temperature parameters of the light source based on the temperature distribution characteristics collected by the sensor using a data analysis model. Through the linkage adjustment of temperature control and light efficiency, the dual balance of optical performance and heat dissipation performance is realized. At the same time, the adaptive adjustment module automatically adjusts the light source power based on real-time light intensity through light-sensitive sensors and ambient light analysis units, and this optical closed-loop adjustment principle ensures comfortable lighting and energy-saving operation of the lamp in different environments. The communication module is based on the layered communication principle of Zigbee and Wi-Fi dual protocol cooperation, Zigbee protocol is used for short-distance, low-power data transmission at the lamp end, and Wi-Fi protocol is used for wide-area connection with external intelligent terminals, so as to realize the remote transmission of operation state and temperature distribution data. This layered communication structure takes into account low power consumption and high bandwidth, improving the reliability and applicability of the system. Finally, the fault detection module uses pattern recognition and threshold judgment techniques to identify potential fault risks by correlating temperature field distribution characteristics and light adjustment parameters. When the system detects temperature anomalies or light efficiency anomalies, it will generate a fault warning message and feed it back to the intelligent terminal through the communication module, thereby realizing predictive maintenance. This fault warning mechanism avoids sudden failures caused by accumulated faults, improving the safety and maintainability of the system.
[0024] Specifically, when the control module analyzes the temperature field distribution characteristics of the light source module based on the data collected by the temperature sensor, it includes: the control module is also used to obtain the temperature gradient of different positions of the light source module, and according to the temperature gradient greater than the preset gradient threshold, it is determined as a local overheating area; the control module is also used to determine the first temperature characteristic according to the ratio of the temperature change rate in the local overheating area to the preset change rate threshold; the control module is also used to determine the second temperature characteristic according to the difference between the overall average temperature of the light source module and the preset average temperature threshold; the control module is also used to determine the temperature field distribution characteristics of the light source module according to the sum of the first temperature characteristic and the second temperature characteristic.
[0025] Specifically, when the control module adjusts the brightness output and the color temperature parameter of the light source module according to the temperature field distribution characteristics, if the temperature field distribution characteristics is greater than or equal to a preset temperature field distribution characteristic threshold, the control module reduces the overall output power of the light source module and adjusts the color temperature parameter to a cold light mode; if the temperature field distribution characteristics is less than the preset temperature field distribution characteristic threshold, the control module maintains the current output power and the color temperature parameter of the light source module unchanged.
[0026] Specifically, when the control module adjusts the running state of the light source module in response to the temperature field distribution characteristics and the illumination adjustment parameter, if both the temperature field distribution characteristics and the illumination adjustment parameter are greater than a preset threshold, the control module reduces the output power of the light source module and starts the thermoelectric cooling fin for active cooling; if the temperature field distribution characteristics is less than the preset threshold and the illumination adjustment parameter is greater than the preset threshold, the control module only reduces the output power of the light source module; if both the temperature field distribution characteristics and the illumination adjustment parameter are less than the preset threshold, the control module maintains the current running state of the light source module.
[0027] Specifically, when the control module adjusts the running state of the light source module based on the temperature field distribution characteristics and the illumination adjustment parameter, the control module further determines a first running state factor according to the ratio of the temperature field distribution characteristics of the light source module to a preset temperature field distribution characteristic threshold; the control module further determines a second running state factor according to the ratio of the illumination adjustment parameter of the light source module to a preset illumination adjustment parameter threshold; the control module further determines a comprehensive running state parameter of the light source module according to the sum of the first running state factor and the second running state factor; and the control module further adjusts the output power and the color temperature parameter of the light source module according to the comprehensive running state parameter.
[0028] Specifically, when the control module adjusts the output power and the color temperature parameter of the light source module based on the comprehensive running state parameter, if the comprehensive running state parameter is greater than or equal to a preset comprehensive running state parameter threshold, the control module reduces the output power of the light source module and adjusts the color temperature parameter to a cold light mode; if the comprehensive running state parameter is less than the preset comprehensive running state parameter threshold, the control module maintains the current output power and the color temperature parameter of the light source module unchanged.
[0029] Specifically, when the control module determines whether to start the thermoelectric cooling fin based on the preset temperature field distribution characteristic threshold and the current temperature field distribution characteristics when the comprehensive running state parameter of the light source module does not meet the preset standard, if the preset temperature field distribution characteristic threshold is less than or equal to the current temperature field distribution characteristics, the control module starts the thermoelectric cooling fin; if the preset temperature field distribution characteristic threshold is greater than the current temperature field distribution characteristics, the control module does not start the thermoelectric cooling fin.
[0030] It can be understood that the control module obtains temperature data of different positions of the light source module through the temperature sensor, and calculates the temperature gradient. When the local temperature gradient exceeds the threshold value, it is determined that the local overheating area; at the same time, the threshold ratio of the temperature change rate in the area is combined to form the first temperature feature. On the other hand, the system extracts the second temperature feature through the difference between the overall average temperature of the light source and the preset threshold value. By adding the two types of feature values, a quantitative description of the overall temperature field distribution of the light source can be formed. This reflects the temperature field feature modeling principle based on gradient and rate analysis, which can more comprehensively capture the heat distribution law of the light source. Secondly, the control module compares the temperature field distribution feature with the preset threshold value, if the value is high, the light source power is reduced and the color temperature is adjusted to the cold light mode to suppress the temperature rise; if the value is lower than the threshold value, the current output is maintained. This logic reflects the heat-driven light efficiency linkage adjustment principle, that is, through dynamic feedback of the temperature control signal, the light source still maintains stable light efficiency under different heat loads. Further, the control module combines the temperature field distribution feature with the illumination adjustment parameter to form a composite decision logic: when both exceed the threshold value, the power is reduced and the thermoelectric refrigeration piece is started to actively cool; when only the illumination adjustment parameter is high, only the power is adjusted; when both are normal, the current state is maintained. This dual-parameter coupling control principle realizes the coordinated adjustment of temperature and illumination, and improves the adaptability of the system in complex environments. On this basis, the control module normalizes the temperature field distribution feature and the illumination adjustment parameter into operating state factors respectively, and calculates the sum as a comprehensive operating state parameter, which is compared with the preset threshold value to determine whether to reduce the power and adjust the color temperature. This process reflects the multi-factor fusion parameter modeling principle, that is, through quantization and weighting, multiple operating indicators are integrated into a unified control variable, so as to realize more accurate dynamic management. Finally, when judging whether to enable the thermoelectric refrigeration piece, the control module adopts the direct comparison of the preset temperature field threshold value and the current temperature field feature, if the current heat level exceeds the threshold value, the refrigeration piece is triggered; otherwise, it is not started. This mechanism reflects the active cooling trigger principle based on critical value determination, which avoids waste of refrigeration resources and ensures safe operation of the light source under high heat risk.
[0031] Specifically, when the adaptive adjustment module adjusts the output power of the light source module based on the change of the ambient light intensity, the adaptive adjustment module further determines a first light intensity feature according to a ratio of a change amount of the ambient light intensity to a preset change amount threshold value; the adaptive adjustment module further determines a second light intensity feature according to a difference between an average value of the ambient light intensity and a preset average light intensity threshold value; the adaptive adjustment module further determines the light adjustment parameter of the light source module according to a sum of the first light intensity feature and the second light intensity feature; and the adaptive adjustment module further adjusts the output power of the light source module according to the light adjustment parameter.
[0032] It can be understood that the adaptive adjustment module collects ambient light intensity data in real time through the photosensitive sensor and calculates the change amount of the light intensity. When the change amount exceeds the preset change threshold, the system can identify the mutation of the ambient light. This mechanism embodies the light dynamic feature extraction principle based on the change rate, which can capture the fluctuation of the ambient light in time, thereby providing a basis for subsequent adjustment. Secondly, the module also extracts a second light intensity feature through the difference between the average value of the ambient light intensity and the preset average threshold, which reflects the long-term or overall brightness level of the ambient light. This process embodies the light baseline feature modeling principle based on the average value, which helps the system to judge whether the current ambient light is too bright or too dark, and provides a stable reference for power adjustment. Subsequently, the adaptive adjustment module adds the first light intensity feature (change amount feature) and the second light intensity feature (average value feature) to form the light adjustment parameter of the light source module. This multi-feature fusion parameterization modeling principle can consider the instantaneous fluctuation and overall brightness of the light, and provide a quantitative basis for the adjustment of the output power. Finally, the system dynamically adjusts the output power of the light source module according to the light adjustment parameter, realizing the adaptive response to the change of the ambient light. This adjustment mechanism embodies the closed-loop light intensity adjustment principle based on real-time feedback, which not only guarantees the comfort and visibility of the lighting, but also optimizes the energy utilization efficiency.
[0033] In the specific embodiments in the present application, the above steps realize the scene in the following manner: in actual application, the LED chip of the light source module generates heat, which is transmitted to the aluminum substrate through the heat-conducting silica gel layer, and further conducted to the heat dissipation shell. The heat-conducting fins in the heat dissipation shell uniformly distribute the heat, and the micro fan forcibly flows air to accelerate the heat dissipation. The temperature sensor collects temperature data at different positions of the light source module in real time and transmits them to the control module. The control module calculates the temperature field distribution characteristics according to the temperature data, and if the temperature gradient is greater than the preset gradient threshold, it is determined as a local overheating area. The ratio of the temperature change rate in the local overheating area to the preset change rate threshold is determined as the first temperature feature, and the difference between the overall average temperature of the light source module and the preset average temperature threshold is determined as the second temperature feature. The sum of the first temperature feature and the second temperature feature is the temperature field distribution characteristic of the light source module.
[0034] When the temperature field distribution characteristic is greater than or equal to a preset temperature field distribution characteristic threshold, the control module reduces the overall output power of the light source module and adjusts the color temperature parameter to a cold light mode. If the temperature field distribution characteristic is less than the preset temperature field distribution characteristic threshold, the current output power and the color temperature parameter are maintained unchanged. Meanwhile, the photosensitive sensor in the adaptive adjustment module monitors the ambient light intensity in real time, and a ratio of a change amount of the ambient light intensity to a preset change amount threshold is determined as a first light intensity characteristic, and a difference between an average value of the ambient light intensity and a preset average light intensity threshold is determined as a second light intensity characteristic. The sum of the first light intensity characteristic and the second light intensity characteristic is the light adjustment parameter of the light source module. Based on the light adjustment parameter, the control module adjusts the output power of the light source module.
[0035] The control module also adjusts the operating state of the light source module in response to the temperature field distribution characteristic and the light adjustment parameter. If both are greater than a preset threshold, the output power of the light source module is reduced and the thermoelectric cooling piece is started to actively cool. If the temperature field distribution characteristic is less than the preset threshold and the light adjustment parameter is greater than the preset threshold, only the output power of the light source module is reduced. If both are less than the preset threshold, the current operating state is maintained. In addition, the control module calculates a ratio of the temperature field distribution characteristic to the preset temperature field distribution characteristic threshold as a first operating state factor, and a ratio of the light adjustment parameter to a preset light adjustment parameter threshold as a second operating state factor, and the sum of the two is the comprehensive operating state parameter. If the comprehensive operating state parameter is greater than or equal to a preset comprehensive operating state parameter threshold, the output power of the light source module is reduced and the color temperature parameter is adjusted to a cold light mode; if the comprehensive operating state parameter is less than the preset comprehensive operating state parameter threshold, the current output power and the color temperature parameter are maintained unchanged.
[0036] The communication module transmits the operating state data and the temperature distribution data of the light source module to the external intelligent terminal. Specifically, the communication module sends the data packets to the gateway device after packaging by Zigbee protocol, and the gateway device forwards the data to the external intelligent terminal by Wi-Fi protocol. The external intelligent terminal analyzes the received data and displays the operating state and the temperature distribution data of the light source module on the user interface. The user can remotely adjust the operating parameters of the light source module through the interface. The fault detection module monitors the operating state of the light source module, and determines whether there is a potential fault risk based on the temperature field distribution characteristic and the light adjustment parameter. If there is a potential fault risk, a fault warning information is generated and sent to the external intelligent terminal through the communication module.
[0037] In a specific application scenario, the system is applied to a high-power industrial lighting scenario. The LED chips of the light source module continuously generate a large amount of heat, which is transferred to the aluminum substrate through the heat-conducting silica gel layer and diffused through the heat-conducting fins on the heat dissipation shell. The micro fan operates at a preset speed to ensure that the air flow carries away the heat. The temperature sensors are arranged at the top, middle and bottom of the light source module to collect temperature data in real time. The control module determines the local overheating area according to the temperature data and adjusts the output power and color temperature parameters of the light source module. For example, when the top temperature gradient exceeds the preset gradient threshold, the control module reduces the overall output power of the light source module and switches to the cold light mode. At the same time, the light sensor monitors the ambient light intensity, and if the ambient light intensity is lower than the preset average light intensity threshold, the control module increases the output power of the light source module to meet the lighting needs.
[0038] In another application scenario, the system is applied to a smart home lighting scenario. The user checks the running state and temperature distribution data of the light source module through the external intelligent terminal. When the system detects a local overheating area, the thermoelectric refrigeration piece starts active cooling, and the output power of the light source module is reduced. The user can remotely adjust the brightness and color temperature parameters of the light source module through the intelligent terminal according to actual needs. For example, when used at night, the user can adjust the color temperature parameters of the light source module to warm light mode to create a comfortable atmosphere.
[0039] The various modules of the system work cooperatively to achieve precise control and optimization of the running state of the light source module. Through real-time monitoring of the temperature sensor and the light sensor, the control module can dynamically adjust the output power and color temperature parameters of the light source module to ensure the consistency and stability of the lighting effect. The cooperation of the communication module and the external intelligent terminal enables the user to remotely monitor and adjust the running state of the system, improving the intelligent level of the system. The presence of the fault detection module further enhances the reliability of the system, which can issue warning information before potential faults occur to avoid lighting interruption or performance degradation caused by faults. In order to better enable relevant personnel in the technical field to fully understand and implement the present application, the specific implementation principles of the present application are further described below in conjunction with specific application scenarios.
[0040] First, in the high-power industrial lighting scenario, the LED chips of the light source module work continuously and generate a large amount of heat. The heat is transferred to the aluminum substrate through the heat-conducting silica gel layer and diffused through the heat-conducting fins on the heat dissipation shell. At this time, the micro fan operates at a preset speed to ensure that the air flow carries away the heat. The temperature sensors are arranged at the top, middle and bottom of the light source module to collect real-time temperature data at these positions. After receiving the data transmitted by the temperature sensors, the control module calculates the temperature gradient of the light source module at different positions. If the temperature gradient of a certain area is greater than the preset gradient threshold, it is determined that this area is a local overheating area. Subsequently, the control module calculates the ratio of the temperature change rate in the local overheating area to the preset change rate threshold as the first temperature feature; at the same time, it calculates the difference between the overall average temperature of the light source module and the preset average temperature threshold as the second temperature feature. Add the first temperature feature and the second temperature feature to get the temperature field distribution feature of the light source module. If the temperature field distribution feature is greater than or equal to the preset temperature field distribution feature threshold, the control module reduces the overall output power of the light source module and adjusts the color temperature parameter to the cold light mode. For example, when the temperature at the top of the light source module exceeds the preset gradient threshold, the control module will automatically reduce the overall output power of the light source module and switch to the cold light mode to reduce heat accumulation.
[0041] Second, in terms of environmental light intensity monitoring, the photosensitive sensor in the adaptive adjustment module monitors the light intensity of the surrounding environment in real time. The control module calculates the ratio of the change amount of the environmental light intensity to the preset change amount threshold as the first light intensity feature based on the data collected by the photosensitive sensor; at the same time, it calculates the difference between the average value of the environmental light intensity and the preset average light intensity threshold as the second light intensity feature. Add the first light intensity feature and the second light intensity feature to get the light adjustment parameter of the light source module. Based on this parameter, the control module dynamically adjusts the output power of the light source module. For example, when the environmental light intensity is lower than the preset average light intensity threshold, the control module increases the output power of the light source module to meet the lighting needs.
[0042] Meanwhile, the control module also considers the temperature field distribution characteristics and the light adjustment parameters to adjust the operating state of the light source module. If both are greater than the preset threshold, the control module reduces the output power of the light source module and starts the thermoelectric cooling fin to actively cool. The thermoelectric cooling fin is tightly attached to the center area of the heat dissipation shell through the heat conduction pad, quickly absorbing and dissipating the heat of the local overheated area. If the temperature field distribution characteristics are less than the preset threshold and the light adjustment parameters are greater than the preset threshold, only the output power of the light source module is reduced. If both are less than the preset threshold, the current operating state is maintained unchanged. In addition, the control module calculates the ratio of the temperature field distribution characteristics to the preset temperature field distribution characteristic threshold as the first operating state factor, and calculates the ratio of the light adjustment parameters to the preset light adjustment parameter threshold as the second operating state factor, and the sum of the two is the comprehensive operating state parameter. If the comprehensive operating state parameter is greater than or equal to the preset comprehensive operating state parameter threshold, the control module reduces the output power of the light source module and adjusts the color temperature parameter to the cold light mode; if the comprehensive operating state parameter is less than the preset comprehensive operating state parameter threshold, the current output power and color temperature parameter are maintained unchanged. In the smart home lighting scene, the communication module sends the operating state data and temperature distribution data of the light source module to the gateway device after grouping and packaging through the Zigbee protocol. The gateway device forwards the data to the external smart terminal through the Wi-Fi protocol. The external smart terminal parses the received data and displays the operating state and temperature distribution data of the light source module on the user interface. The user can remotely adjust the operating parameters of the light source module through the interface. For example, when used at night, the user can adjust the color temperature parameter of the light source module to the warm light mode through the external smart terminal to create a comfortable home atmosphere. When the system detects that the light source module has a local overheated area, the thermoelectric cooling fin starts to actively cool, and the output power of the light source module is reduced to avoid further heat accumulation. The fault detection module continuously monitors the operating state of the light source module, and judges whether there is a potential fault risk based on the temperature field distribution characteristics and the light adjustment parameters. If there is a potential fault risk, a fault warning information is generated and sent to the external smart terminal through the communication module. For example, when the temperature field distribution characteristics are continuously higher than the preset threshold and cannot be effectively cooled by the thermoelectric cooling fin, the fault detection module will issue a warning information to prompt the user to take timely measures to avoid performance degradation or damage of the light source due to overheating.
[0043] It can be seen that through the above steps, the various modules of the system work together to achieve precise control and optimization of the operating state of the light source module. The real-time monitoring data of the temperature sensor and the photosensitive sensor provides a reliable basis for the control module to ensure that the output power and color temperature parameters of the light source module can be dynamically adjusted according to actual needs. The cooperation of the communication module and the external intelligent terminal enables users to remotely monitor and adjust the system operating state, improving the intelligent level of the system. The presence of the fault detection module further enhances the reliability of the system, which can issue early warning information before potential faults occur, avoiding lighting interruption or performance degradation caused by faults.

Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present application shall be included in the protection scope of the present application.
[0045] In the above embodiment, the light source module is designed with independent light source units, each unit is tightly combined with the aluminum substrate through the heat-conducting silicone layer, and is further fixed with the heat dissipation shell, so that the working heat of the LED chip can be quickly conducted to the heat dissipation shell, realizing efficient heat conduction and avoiding light source attenuation and shortening of service life caused by local overheating. Secondly, parallel heat-conducting fins are arranged inside the heat dissipation shell, and a micro fan is used to enhance air flow, which can significantly improve the heat dissipation efficiency and keep the light source in a suitable working temperature range, thereby ensuring the stability and durability of the light source. Meanwhile, a temperature regulation module is introduced, which can realize precise temperature control by real-time monitoring of the temperature field distribution of each region of the light source module through distributed temperature sensors, combined with the active cooling means of the thermoelectric refrigeration piece, effectively reducing the hot spot phenomenon and prolonging the service life of the whole lamp. In addition, the control module can dynamically adjust the brightness output and color temperature parameters of the light source by analyzing the temperature field distribution characteristics, so that the light source can maintain stable light emitting quality under different temperature conditions, avoiding the phenomenon of light efficiency decline or color deviation caused by temperature fluctuation. In combination with the ambient light analysis function of the adaptive adjustment module, the system can automatically adjust the output power according to the real-time change of external light intensity, ensuring the comfort and visual effect of lighting, and realizing the effect of energy saving and consumption reduction. Finally, the display module can intuitively display the operating state and temperature distribution data of the light source, so that users or maintenance personnel can master the working condition of the system in real time, facilitating operation and maintenance and fault diagnosis. This visual monitoring not only improves the intelligent level of the system, but also provides data support for subsequent optimization and debugging.
