[0002] With the development of modern building technology and the popularization of the concept of green energy conservation, the wall lighting system, as an important means to enhance the aesthetic appearance and night functionality of buildings, has been widely applied to various buildings. Wall lighting can not only enhance the visual appeal of buildings but also provide necessary night navigation and safety protection for pedestrians.

[0003] In practical applications, unreasonable wall lighting design often leads to a great waste of electric energy. On the one hand, if the lighting fixtures are arranged too densely or the brightness is set too high, it will not only cause light pollution and affect the quality of life of surrounding residents but also consume a large amount of electric energy unnecessarily. On the other hand, the lack of the function of automatically adjusting the brightness according to the change of ambient light makes the lighting system continue to work when the daytime light is sufficient or maintain an unnecessary high brightness when the night traffic is sparse, further exacerbating the waste of energy.

[0004] Therefore, it is necessary to provide a green wall lighting and energy management system that can reduce light pollution and save electric energy. Summary of the Invention

[0036] The green wall lighting and energy management system described above utilizes intelligent control to automatically adjust lighting brightness based on grid load and actual needs, significantly reducing energy consumption.

The system automatically adjusts lighting strategies, improving robustness and flexibility. Real-time monitoring and intelligent control reduce equipment failures caused by uneven or excessive lighting, reducing maintenance frequency and costs.

[0037] Below is a diagram of the Figure 1 , some embodiments of the present application are described in detail. In the absence of conflict, the following embodiments and features in the embodiments can be combined with each other.

[0038] In an embodiment of the present application, a green wall lighting and energy management system 100 is provided, including: a lighting control module 10, including multiple load units 11 connected in series, each of the load units 11 is arranged on a wall; a load detection module 20, used to detect a first voltage value outputted by the lighting brightness in the multiple load units 11; a power grid preset module 30, used to preset an output load segment of the power grid; a comparison module 40, used to compare the output load segment with the first voltage value; and a regulation module 50, used to generate a regulation instruction and control the lighting brightness of the multiple load units 11 according to the comparison value of the comparison module 40.

[0039] Specifically, multiple series-connected load units 11 can be distributed on the wall, with each load unit 11 working together to achieve uniform lighting on the wall. The series connection simplifies line layout, reduces installation costs, and facilitates centralized management and control.

[0040] Furthermore, the load detection module 20 can indirectly reflect the lighting brightness and energy consumption status of the load unit 11 by detecting the voltage value of the load unit 11. This provides the system with real-time energy consumption monitoring capabilities and provides data support for subsequent energy-saving regulation.

[0041] Furthermore, the grid preset module 30 is used to preset the output load segments of the grid and their corresponding time windows and voltage threshold ranges. This module presets different output load segments and their corresponding time windows and voltage threshold ranges according to the load changes and voltage fluctuations of the grid.

[0042] Further, the comparison module 40 compares and matches the first voltage value detected by the load detection module 20 with the preset output load segments of the power grid preset module 30 to determine the range of the current lighting load unit 11 within the preset output load segments.

[0043] Further, the regulation module 50 generates corresponding regulation instructions according to the output result of the comparison module 40, and realizes the goal of energy conservation and consumption reduction by adjusting the lighting brightness of the load unit 11. The regulation instructions can include brightness adjustment, switch control, etc.

[0044] Furthermore, when the daylight is sufficient during the day, the load detection module 20 detects the voltage values of each load unit 11 on the wall in real time. The power grid preset module 30 presets different output load segments, their corresponding time windows and voltage threshold ranges, and compares and matches them with the preset output load segments. According to the matching result, the comparison module 40 will output a corresponding signal to the regulation module 50. The regulation module 50 generates a regulation instruction according to this signal, and reduces or turns off the lighting brightness of some load units 11 through the PWM dimming module to reduce the impact on the power grid and save electric energy. At night or when the light is insufficient, the system automatically adjusts the lighting brightness according to the preset time window and voltage threshold range to meet the lighting requirements and improve the lighting efficiency.

[0045] In a specific embodiment, the load unit 11 is an LED lamp, and the LED lamp is connected with a PWM dimming module for adjusting the lighting brightness of the LED lamp.

[0046] Specifically, the load unit 11 of the lighting system is designed as an LED lamp. Using an LED lamp as the load unit 11 not only reduces the energy consumption of the lighting system, but also extends the service life of the system and reduces the maintenance cost. By adjusting the brightness of the LED lamp, the PWM dimming module helps to reduce energy consumption. During the peak period of the power grid load, the lighting brightness can be reduced to reduce energy consumption; while during the low load period, the lighting level can be increased to meet the user's needs while still maintaining high energy efficiency. The PWM dimming module adjusts the brightness of the LED lamp by changing the duty cycle of the pulse signal. The larger the duty cycle, the brighter the LED lamp; the smaller the duty cycle, the dimmer the LED lamp. This adjustment method is not only precise, but also can keep the color temperature of the LED lamp stable. The PWM dimming module is directly connected to the LED lamp, and the brightness of the LED lamp is adjusted through a control signal. This direct connection method simplifies the system structure and improves the response speed of regulation. At the same time, since the output signal of the PWM dimming module is compatible with the input signal of the LED lamp, no additional conversion circuit is required.

[0047] In a specific embodiment, the green wall lighting and energy management system further includes a clock module for obtaining the current time point and presetting a time window.

[0048] Specifically, the main function of the clock module is to accurately obtain the current time point and preset different time windows according to system requirements. The time window is the time range during which the system performs specific tasks or takes specific measures in different time periods. By presetting the time window, the system can increase the lighting brightness or perform necessary maintenance operations in different time periods, thereby optimizing energy utilization and reducing operating costs.

[0049] Furthermore, in specific applications, the clock module first obtains the current time point and matches it with the preset time window. When the current time point falls within a certain preset time window, the system will perform corresponding operations according to the tasks corresponding to that time window.

[0050] In a specific embodiment, based on the preset time window, the output load section is divided into a first load section, a second load section, and a third load section; the preset time window is continuous first, second, and third time periods, and the first time period corresponds to the first load section, the second time period corresponds to the second load section, and the third time period corresponds to the third load section.

[0051] Specifically, in the embodiment of the present application, the 24 hours of a day in the preset time window are divided into continuous first (0:00 to 6:00), second (6:00 to 18:00), and third (18:00 to 24:00) time periods. The preset time window provides a time framework for the system, enabling the system to automatically adjust the lighting load according to the change of time. The system can automatically adapt to the lighting requirements in different time periods without manual intervention.

[0052] Furthermore, based on the preset time window, the output load section is divided into a first load section, a second load section, and a third load section, and each load section matches the corresponding time period. Adopting different lighting load strategies in different time periods helps to reduce the operating costs and maintenance costs of the lighting system.

[0053] In a specific embodiment, the voltage range of the first load section is 5V to 7V; the voltage range of the second load section is 3V to 5V; the voltage range of the third load section is 7V to 10V.

[0054] Specifically, the voltage range of the first load segment sets a medium voltage threshold (5V - 7V), which can meet general lighting needs while maintaining reasonable energy utilization. The voltage range of the second load segment sets a lower voltage threshold (3V - 5V) for energy conservation, especially during periods with low electricity demand. By reducing the voltage, the energy consumption of the lighting system is reduced, which helps to lower electricity bills and reduce carbon emissions. The third load segment sets a higher voltage threshold (such as 7V - 10V) to meet high-brightness requirements, especially in scenarios where high-brightness lighting is needed, providing sufficient lighting brightness to ensure the lighting effect, and is suitable for night, outdoor, or special lighting needs.

[0055] Further, the first time period (0:00 to 6:00) corresponds to the first load segment. During the night rest period, it provides medium-brightness lighting to meet basic night lighting needs. It will neither be too dazzling to affect rest nor fail to provide sufficient safety lighting. The second time period (6:00 to 18:00) corresponds to the second load segment. During the day and working hours, it provides lower-brightness lighting, mainly for energy conservation, making use of natural light for lighting and reducing the energy consumption of artificial lighting to achieve green lighting. The third time period (18:00 to 24:00) corresponds to the third load segment. During the evening and night activity periods, it provides high-brightness lighting to meet night activity and entertainment needs, ensuring the lighting effect, enhancing the user experience, and at the same time avoiding energy waste.

[0056] In a specific embodiment, the comparison module 40 matches the current time point with a preset time window to determine the output load segment where the current time point is located, and matches the first voltage value with the first load segment, the second load segment, and the third load segment respectively.

[0057] Specifically, the comparison module 40 matches the current time point with a preset time window to determine which output load segment the system should currently be in. At the same time, it also matches the first voltage value with the voltage ranges corresponding to each load segment to determine whether the voltage value is applicable to the current load segment. By matching the current time point with the preset time window, it is determined which output load segment the system should currently be in. For example, if the current time is 7 pm, then the system should be in the third time period (18:00 to 24:00), and the output load segment corresponding to the first voltage value is the third load segment. Through time point matching, the system can automatically adjust the lighting load according to different time periods to adapt to different lighting needs and energy management goals.

[0058] In a specific embodiment, the brightness of the LED lamp is adjusted in the opposite direction to the change of the first voltage value.

[0059] Specifically, the PWM dimming module adjusts the duty cycle according to the received regulation instruction, thereby controlling the brightness of the LED lamp. In this embodiment, the regulation instruction is generated based on the matching result between the current time point and the preset time window, and the matching result between the first voltage value and the voltage range of the load segment. The duty cycle refers to the proportion of the high level in the pulse signal. The larger the duty cycle, the brighter the LED lamp; the smaller the duty cycle, the darker the LED lamp, so that the brightness of the LED lamp is adjusted in the opposite direction to the change of the first voltage value. This adjustment method is not only accurate but also can keep the color temperature of the LED lamp stable.

[0060] Further, the comparison module 40 first obtains the current time point and matches it with the preset time window to determine which time point the system should be at currently. Then, the comparison module 40 matches the first voltage value with the voltage range of the load segment corresponding to the current time point to determine whether the voltage value is applicable to the current load segment. If the first voltage value is within the voltage range of the current load segment, a corresponding regulation instruction is directly generated; if not, the first voltage value is adjusted according to the voltage range of the load segment, and an adjusted regulation instruction is generated. After receiving the regulation instruction, the PWM dimming module adjusts the duty cycle according to the instruction to achieve the reverse adjustment of the brightness of the LED lamp. If the voltage value increases, the duty cycle is decreased to reduce the brightness; if the voltage value decreases, the duty cycle is increased to increase the brightness.

[0061] In a specific embodiment, if within the current time point, the first voltage value exceeds the voltage range of the current output load segment, the regulation module 50 generates a control instruction to reduce or turn off the brightness of the load unit 11.

[0062] Specifically, when the first voltage value exceeds the voltage range of the current output load segment, the regulation module 50 immediately generates corresponding control instructions. These instructions may include reducing the brightness of the load unit 11, turning off some or all of the load units 11, etc. By reducing the brightness or turning off the load unit 11, the system can save energy to the greatest extent while ensuring safety.

[0063] In a specific embodiment, the multiple serially connected load units 11 are powered by time sharing through a bus controller, and each load unit 11 is independently connected to a voltage feedback circuit.

[0064] Specifically, the bus controller, as the core control unit, is responsible for coordinating the power supply timing of multiple load units 11. Through time-sharing power supply, it avoids the instantaneous current overload caused by all load units 11 working simultaneously, reduces the peak power consumption, relieves the power grid pressure, improves the system stability, extends the lamp life, and avoids hardware damage caused by excessive instantaneous current. The voltage feedback circuit monitors the working voltage of each load unit 11 in real time to ensure that the voltage fluctuation is within a controllable range. The independent feedback design enables the status of each load unit 11 to be monitored and controlled individually.

[0065] Further, after the system is started, the first time period: 0:00 - 6:00, the second time period 6:00 - 18:00, and the third time period 18:00 - 24:00 are divided according to the preset time window. Each load segment corresponds to a different voltage threshold range. The first load segment is 5V to 7V, the second load segment is 3V to 5V, and the third load segment is 7V to 10V. The clock module determines the load segment according to the current time point (for example, if the current time is 10:00, it is in the second time period). The load detection module 20 compares the first voltage value collected with the threshold range of the current load segment: if the first voltage value is 4V and within the voltage threshold range of the second load segment, the current brightness is maintained. If the first voltage value exceeds the threshold range (such as detecting 8V), a regulation instruction is triggered. The regulation module 50 adjusts the duty cycle of the PWM dimming module according to the instruction. When the voltage is too high, the duty cycle is reduced to reduce the brightness and current, so that the voltage drops back to the target range. When the voltage is too low, the duty cycle is increased to increase the brightness and current, so that the voltage rises back to the target range.

[0066] In a specific embodiment, the bus controller includes a multiplexer switch array. The power supply line of each load unit 11 is connected to the main power supply through an independent MOSFET switch, and the on-off timing of the MOSFET switch is controlled by the bus controller according to time-sharing power supply.

[0067] Specifically, the multiplexer switch array is the core hardware component of the bus controller, which is used to realize the switching of the power supply lines of multiple load units 11. Each load unit 11 is equipped with an independent MOSFET switch to achieve power supply isolation at the physical level. The bus controller dynamically controls the on-off timing of the MOSFET switch according to the preset time-sharing power supply strategy. Through timing control, it ensures that each load unit 11 is only powered on during the specified period, avoiding current overload caused by simultaneous operation.

[0068] The above are only the implementation manners of the present application. It should be noted here that for those of ordinary skill in the art, without departing from the creative concept of the present application, improvements can still be made, but these all belong to the protection scope of the present application.
