Description

TECHNICAL FIELD

[0001] The present application relates to the field of LED lighting technology, in particular to an LED high-power outdoor area lighting lamp and a control method thereof. BACKGROUND

[0002] At present, high-intensity gas discharge lamps (HID), halogen lamps or traditional LED projectors are commonly used for lighting arrangement in outdoor large areas (such as stadiums, squares, parking lots and high-pole lighting, etc.). The existing LED high-power outdoor area lighting lamps are usually composed of a fixed-structure lamp body shell, an LED light-emitting module and a conventional driving power supply, and some products have basic dimming functions. In order to meet different application scenarios and lighting needs, some high-end lamps introduce power adjustable components and basic sensors, but the overall intelligence and energy efficiency still have a lot of room for improvement.

[0003] The existing high-power outdoor area lighting scheme generally has the following problems: on the one hand, most of the existing lamps lack efficient multi-grade power regulation function. Users can usually only make limited brightness adjustments to the lamps through simple manual switches, relay switches or preset time programs. This kind of adjustment method does not have fine grading and dynamic response capability, resulting in that the lamps cannot flexibly adjust the output power and lighting intensity according to different time periods, activity intensity or use requirements in actual operation, and often remain in high-brightness mode for a long time, causing unnecessary waste of electric energy.

[0004] On the other hand, the existing lamps lack effective linkage with intelligent sensors. Although some products are equipped with simple light control or time control devices, they are mostly single-dimensional passive responses and cannot realize intelligent perception and linkage control of personnel flow, vehicle passing or environmental changes. For example, when there is no personnel or sufficient natural light in the outdoor area, the lamps are still on; when personnel enter at night, the lamps cannot actively adjust the brightness, lighting range or number of lamps according to the position or activity state of the personnel in real time. Such static or preset lighting mode cannot balance energy saving and consumption reduction with on-site experience.

[0005] Therefore, how to realize an intelligent LED high-power outdoor area lighting lamp based on multi-grade power regulation and sensor linkage control, which can dynamically adjust the working state according to the personnel activity information and environmental light intensity in the actual area, effectively improve the lighting energy efficiency and intelligent level, is a key technical problem in the current field that needs to be solved.

[0070] Embodiment 1

[0071] Please see Figures 1-3The embodiment of the present application provides a LED high-power outdoor area lighting lamp, the LED high-power outdoor area lighting lamp comprises a first lamp body shell 1, a power module, an LED light-emitting module, a control circuit, a power selection assembly and a sensor module, wherein,

[0072] The power module is electrically connected with the LED light-emitting module and is used for supplying power for the LED light-emitting module.

[0073] The LED light-emitting module is detachably connected with the first lamp body shell.

[0074] The sensor module is used for acquiring sensing information, and the sensing information comprises personnel activity information and / or illumination intensity information.

[0075] The control circuit is electrically connected with the power selection assembly and the LED light-emitting module, the power selection assembly comprises a preset number of adjustment gears, different adjustment gears correspond to different power outputs and / or brightness states, and the control circuit is used for controlling the working state of the LED light-emitting module according to a preset control mode and the sensing information.

[0076] Specifically, the first lamp body shell 1 is used as the mounting and supporting basis of various functional modules, the structure can be an integrally formed metal shell, has good mechanical strength and protection performance. The LED light-emitting module is detachably connected with the first lamp body shell, so that initial assembly is facilitated, and subsequent maintenance, replacement or upgrading is facilitated. The LED light-emitting module usually comprises high-brightness LED lamp beads, a heat dissipation substrate and a light distribution structure, and can realize efficient and uniform illumination output.

[0077] The power module is arranged in the first lamp body shell 1 and is electrically connected with the LED light-emitting module, and mainly functions to transform commercial power input into constant driving current required by the LED and ensure long-term and stable operation of the lamp.

[0078] The power selection assembly is arranged between the control circuit and the LED light-emitting module and comprises a plurality of adjustment gears, each gear is provided with different power output parameters and / or brightness state parameters. Users can select appropriate lighting power through the assembly according to actual application requirements of specific scenes, so that multi-scene adaptation is realized.

[0079] The control circuit is the intelligent core of the whole lamp, which is electrically connected with the power selection assembly, signal connected with the LED light emitting module, and data interacted with the sensor module. The sensor module includes various sensors for obtaining the environment information of the stadium, such as infrared sensor, microwave radar sensor for detecting personnel activity information, and photosensitive sensor for collecting ambient light intensity information. The control circuit can receive and analyze these sensing information in real time, and dynamically adjust the working state of the LED light emitting module, including on / off control, brightness adjustment and color temperature selection, etc., combined with the preset control mode.

[0080] For example, when no personnel activity is detected in the target scene and the ambient light is sufficient, the control circuit can automatically reduce the power of the lamp or turn off the lamp, so as to achieve the purpose of energy saving; when personnel enter or the ambient light is insufficient, the lamp is automatically adjusted to the appropriate working state to ensure the lighting needs of sports activities. The above design effectively improves the intelligent level and energy utilization efficiency of the lighting system, and improves the operation experience of the stadium.

[0081] In summary, through the collaborative design of structural modularization, electrical intelligence and sensing linkage, the LED high-power outdoor area lighting lamp for the stadium can flexibly adapt to various scenes, and realize efficient, intelligent and energy-saving lighting control.

[0082] Preferably, the first lamp body shell includes two LED light emitting modules, denoted as first LED light emitting module 12, the first lamp body shell 1 is an integrally formed die-cast aluminum structure, the first lamp body shell is externally provided with a plurality of heat sinks for improving the heat dissipation efficiency, and the bottom of the first lamp body shell is provided with a first wire slot for electrical wiring.

[0083] Specifically, the first lamp body shell 1 can accommodate two LED light emitting modules, so as to realize higher power light source integration in the same lamp body structure. The first lamp body shell is integrally formed by die-casting aluminum process, compared with the traditional split structure, not only ensures the mechanical strength and stability of the first lamp body shell, improves the overall sealing and protection performance, but also reduces the number of splicing and fasteners, reduces the complexity of assembly and maintenance. The integrally formed design is conducive to realizing complex three-dimensional geometric shapes, such as integrated fins and ventilation channels, further improving the heat dissipation effect.

[0084] The first lamp body shell is externally provided with a plurality of regularly distributed heat sinks, in an embodiment, the heat sink is a heat dissipation fin, which greatly increases the contact area of the first lamp body shell with the outside air, effectively improving the heat release efficiency. When the LED light source module works, the heat generated by the LED light source module is rapidly conducted and dissipated to the outside through the fins, preventing the LED junction temperature from being too high, which helps to maintain the stable work of the LED chip, prolongs the service life of the lamp, and prevents performance degradation caused by overheating.

[0085] In addition, the bottom of the first lamp body shell is further provided with a first wire slot for electrical wiring. The wire slot is used for the layout and protection of internal electrical wiring, facilitating the reliable connection of multiple LED light-emitting modules, power modules, control circuits and other units, and effectively avoiding the interference of cables with the heat dissipation structure, thereby improving the overall standardization and safety of the lamp structure.

[0086] In summary, the embodiment integrates the structure by die-casting aluminum, optimizes the multiple sets of heat dissipation fins, and designs the independent wire slot, so that the LED high-power outdoor area lighting lamp further improves the convenience of installation, maintenance and electrical safety while ensuring excellent heat dissipation performance and mechanical strength, and is particularly suitable for high-power and high-demand outdoor lighting application scenarios such as stadiums.

[0087] Preferably, the LED high-power outdoor area lighting lamp further comprises a second lamp body shell 2, which comprises one LED light-emitting module (denoted as a second LED light-emitting module 23) and a second wire slot provided at the bottom of the second lamp body shell. The second lamp body shell is fixedly connected to the first lamp body shell by screws. After the first lamp body shell and the second lamp body shell are connected, the first wire slot and the second wire slot are in communication to form a through electrical wiring channel. The splicing interfaces of the first lamp body shell 1 and the second lamp body shell 2 are respectively provided with the heat sinks. A sealing rubber ring is provided between the heat sinks of the first lamp body shell and the second lamp body shell, and the sealing rubber ring is compressed between the two heat sinks when the screws are tightened.

[0088] Specifically, in the embodiment, the LED high-power outdoor area lighting lamp not only comprises a first lamp body shell, but also comprises a second lamp body shell, for realizing high-power and modular splicing design.

[0089] The second lamp body shell is internally provided with a second LED light-emitting module 23, and the bottom thereof is provided with a second wire slot for accommodating and guiding electrical wiring. The size, cross-sectional shape and position of the second wire slot are matched with those of the first wire slot at the bottom of the first lamp body shell, so as to realize accurate alignment and reliable splicing when the two are connected. The first wire slot and the second wire slot are in communication to form an internal wiring channel, and all lines are transmitted inside the shell, thereby eliminating exposed wiring.

[0090] The second lamp body shell is fixedly connected with the first lamp body shell by two screws (denoted as first screw 21 and second screw 22 respectively). After assembly, the first wire passing groove and the second wire passing groove are in communication with each other, forming an electrical wiring channel that penetrates the splicing interface. Since the wiring channel is completely located in the internal structure of the two lamp body shells, all electrical connections are transmitted through the internal channel and are not exposed outside the lamp, thereby avoiding the safety risks, visual interference and protection hazards caused by the traditional external jumper cable.

[0091] To ensure waterproof performance, the splicing interface of the first lamp body shell and the second lamp body shell is respectively provided with a radiator, and a sealing rubber ring is arranged between the two radiators. The sealing rubber ring is made of a high-temperature-resistant and anti-aging elastic material, and is compressed between the two radiators during screw tightening, forming a stable and reliable sealing structure that blocks the infiltration of external media such as rainwater and dust into the internal wiring channel through the splicing, further ensuring the insulation and safety of the internal electrical connections.

[0092] Referring to Figure 4a and Figure 5a , the light distribution curve and the equal illuminance distribution of the LED high-power outdoor area lighting lamp in the embodiment of the application are shown. In this embodiment, two LED light emitting modules are arranged in the first lamp body shell, and the light distribution curve of the lamp is as shown in Figure 4a , where the horizontal coordinate is the Gamma angle and the vertical coordinate is the light intensity distribution, with units of cd / klm. The red curve represents the C0-C180 plane, and the blue curve represents the C90-C270 plane.

[0093] As can be seen from the figure, the two curves are basically coincident, indicating that the light distribution of the lamp in the horizontal and vertical directions is relatively consistent, which belongs to symmetrical light distribution. The specific data shows that the light intensity reaches a maximum value of nearly 2000 cd / klm at 0°, and gradually decreases as the exit angle increases, decaying to less than 500 cd / klm at about 30°, and the overall distribution characteristic is longitudinal extension and central light intensity protrusion.

[0094] Figure 5a is the corresponding equal illuminance distribution diagram, the horizontal and vertical coordinates are in units of lamp installation height (30 feet), and equal illuminance curves of different colors correspond to different illuminance levels. The red area corresponds to 20 Lux, the blue area corresponds to 10 Lux, the dark blue area corresponds to 5 Lux, the green area corresponds to 1 Lux, the light green area corresponds to 0.5 Lux, the outermost light green curve corresponds to 0.1 Lux, and the black curve represents the 50% maximum light intensity range, and the red dotted line represents the maximum light intensity center position.

[0095] As can be seen from the figure, a high-illuminance core area is formed directly below the lamp, the central illuminance can reach more than 20 Lux, and the illuminance can still be maintained at about 5 Lux within a range of twice the installation height, even within a range of three to four times the installation height, it still has a coverage of more than 1 Lux, the overall equal-illuminance distribution is annular and centrally concentrated, and can form a lighting effect with strong far-shooting ability and high central brightness in the target area, and is particularly suitable for use in outdoor stadiums, roads or outdoor areas requiring directional concentrated lighting.

[0096] Referring to Figure 4b and Figure 5b , the light distribution curve and equal-illuminance distribution of the LED high-power outdoor area lighting lamp in the embodiment of the application when simultaneously including the first lamp body shell and the second lamp body shell are shown. In this embodiment, the first lamp body shell and the second lamp body shell are fixedly connected by screws and jointly accommodate three LED light-emitting modules, and the light distribution curve thereof is as shown in Figure 4b . As can be seen from the figure, the red curve corresponds to the C0-C180 plane, and the blue curve corresponds to the C90-C270 plane, both of which are also relatively close, indicating that the light distribution of the lamp is basically symmetrical in the horizontal and vertical directions. Figure 4a Compared with the double-module structure of , the light intensity peak value under the three-module structure is about 1250 cd / klm, which is relatively reduced, but the light beam range is more full, the distribution is wider, and the overall light emission is more uniform.

[0097] Figure 5b is the equal-illuminance distribution diagram corresponding to Figure 4b . When the installation height of the lamp is 30 feet, the equal-illuminance curves of different colors still correspond to different illuminance levels: the red area corresponds to 20 Lux, the blue area corresponds to 10 Lux, the dark blue area corresponds to 5 Lux, the green area corresponds to 1 Lux, the light green area corresponds to 0.5 Lux, the outermost light green curve corresponds to 0.1 Lux, and the black curve is the range of 50% maximum light intensity, and the red dotted line represents the position of the maximum light intensity center. As can be seen from the figure, compared with the double-module lamp of Figure 5a , the central high-illuminance area of the three-module lamp is relatively reduced, but the distribution of the illuminance in the periphery is more balanced, the shape of the equal-illuminance line tends to be round, the coverage range is expanded, and the brightness decay is more gentle. In other words, the double-module ( Figure 5a ) emphasizes the high brightness of the central area, while the three-module ( Figure 5b ) reduces the single-point peak illuminance while improving the uniformity and coverage range of the overall light field, which is suitable for application scenarios requiring large-area uniform lighting.

[0098] Preferably, the sensor module comprises an infrared motion sensor and / or an ambient light sensor, and the control circuit is configured to adjust the working state of the LED light-emitting module in combination with the personnel activity information obtained by the infrared motion sensor and / or the illumination intensity information obtained by the ambient light sensor.

[0099] The sensor module can integrate an infrared motion sensor, an ambient light sensor, or a combination of the two, as needed. The infrared motion sensor is used to detect the activity state of personnel in the lighting coverage area of the stadium in real time, including detecting the entry, exit, and activity in a specific area of personnel. This sensor achieves non-contact detection by sensing human infrared radiation, and has the advantages of sensitive response and strong anti-interference capability. The ambient light sensor is used to monitor the illumination intensity in the stadium in real time, and can feedback the brightness level of the current environment according to the changes in natural light (such as daytime, nighttime, overcast day, etc.), providing data support for subsequent lighting adjustment.

[0100] The infrared motion sensor and the ambient light sensor respectively transmit the collected personnel activity information and ambient light intensity information to the control circuit. The control circuit can fuse and process the two types of information according to a preset control logic. For example, when personnel activity is detected in the stadium area and the ambient light is below a set threshold, the LED light-emitting module is automatically turned on or turned off to achieve the best lighting effect; if there is no personnel activity and the natural light is sufficient, the lighting power is reduced or some lamps are turned off to achieve energy-saving operation.

[0101] Through the data input of the above-mentioned sensors, the control circuit can perform multi-level adjustment on the LED light-emitting module, including but not limited to on-off control, brightness adjustment, color temperature adjustment, and delay extinguishing, etc. This not only realizes intelligent control of the lamps, but also effectively prolongs the service life of the lamps, and reduces maintenance and energy consumption costs.

[0102] Preferably, the first lamp body shell comprises a mounting interface 13 for connecting different types of mounting assemblies, the mounting assemblies comprising at least one of a sliding sleeve type mounting member, a lamp pole mounting arm, a triangular support, a universal support, an adjustable mounting arm, a universal mounting support, and a wall mounting support.

[0103] Specifically, the first lamp body shell is provided with a standardized mounting interface, which can be a threaded hole, a clamping groove, a flange, a sliding groove, or other mechanical connection structures, to facilitate reliable docking with various types of mounting assemblies. This design enables the lamps to be quickly replaced or selected with appropriate mounting methods according to different application scenarios when the lamps are factory-finished or installed on site, thereby improving the versatility and flexibility of the lamps.

[0104] The mounting assemblies include but are not limited to the following types:

[0105] Sliding sleeve type mounting: suitable for lamp poles or beam structures, quick positioning and installation can be achieved through sliding and fastening, facilitating height and angle adjustment.

[0106] Lamp pole mounting arm: suitable for direct installation on round or square lamp poles, commonly used in stadiums, high-pole lighting and other occasions.

[0107] Triangular support, universal support, adjustable mounting arm, these components support multi-angle and multi-direction adjustment, facilitating precise control of the lighting range of the lamp, meeting the lighting needs of multiple areas and different directions.

[0108] Universal mounting bracket adapts to various non-standard or special structures, improving the adaptability of the lamp to complex environments.

[0109] Wall-mounted bracket is used in places where the lamp needs to be fixed on a vertical surface such as a wall, expanding the application space of the lamp.

[0110] Through the compatible design of the above-mentioned multiple types of mounting components, the lamp can not only be installed in multiple positions such as standard lamp poles, beams, walls, etc., but also can be flexibly adjusted in angle, direction and height according to the specific needs of the lighting site, greatly improving the construction convenience and maintenance efficiency of the lamp.

[0111] Preferably, the mounting interface is used to install one, two or three LED high-power outdoor area lighting lamps on the same lamp pole, and the adjacent two LED high-power outdoor area lighting lamps are adjustably arranged at different included angles through the mounting assembly to realize directional lighting of different areas of the stadium.

[0112] Specifically, the mounting interface and matching mounting assembly allow one, two or three LED high-power outdoor area lighting lamps to be installed on the same lamp pole. Each lamp is connected to the lamp pole through an independent mounting seat, and different lamps are independent of each other, facilitating subsequent individual disassembly, maintenance or upgrade. The multi-lamp shared pole design reduces the number of lamp poles and the amount of foundation work, optimizing the space utilization rate and overall aesthetics of the site. Adjacent two LED high-power outdoor area lighting lamps are provided with an adjustable included angle mechanism through the mounting assembly. This mechanism can take the form of a rotating shaft, a gear, a positioning hole or a universal joint, allowing the installer to flexibly adjust the illumination direction and included angle of each lamp according to the lighting needs. For example, the three lamps can be directed to the middle zone, the side zone and the spectator zone of the stadium, respectively, to realize zoned directional lighting. The included angle adjustment usually has a limiting or locking device to ensure that the lamp is stable after being adjusted in place. Through the above multi-lamp shared pole arrangement with adjustable included angle, different functional areas of the stadium can be accurately covered, avoiding the dead angle, overlap or light pollution problems of single lamp lighting. According to the layout of the venue, the requirements of the competition or the distribution of the audience, the illumination direction of each lamp can be flexibly set to improve the lighting uniformity and efficiency, meeting the requirements of multi-scene, zoned dynamic lighting.

[0113] Preferably, the power supply driving module comprises a surge protection device, which comprises a protection circuit between lines and to ground, and can withstand high amplitude transient overvoltage induced by power distribution lines.

[0114] The power supply driving module is integrated with a special surge protection device, which specifically comprises a protection circuit between lines (such as between the live wire and the zero line) arranged at the AC input end, and a protection circuit to ground arranged between the AC input end and the ground end. The device usually adopts metal oxide varistors (MOV), gas discharge tubes, TVS diodes and other elements, and realizes comprehensive protection of various surge paths through reasonable arrangement and hierarchical protection.

[0115] During the operation of the lamp, high amplitude transient overvoltage (i.e. surge) may be generated in the power distribution line due to lightning strike, power grid switching, start and stop of large equipment and other factors. The surge protection device can instantaneously shunt or absorb excess voltage under these abnormal conditions, effectively limiting the peak voltage applied to the power module and the LED light emitting module, and preventing internal component damage.

[0116] When a surge voltage appears in the power distribution line, the surge protection device can respond to high voltage between the live wire and the zero line, the live wire and the ground, and the zero line and the ground in real time, realizing multi-level and all-round surge suppression. This design ensures that the lamp can operate stably for a long time even in complex or harsh power supply environment, greatly improving the anti-interference ability and electrical safety of the whole lamp.

[0117] Embodiment 2

[0118] Referring to Figure 6 , the embodiment of the present application also provides a control method of an LED high-power outdoor area lighting lamp, which is used for the LED high-power outdoor area lighting lamp described in embodiment 1, and the method comprises the following steps:

[0119] S1, acquiring scene information of a target outdoor area where the lighting lamp is located, wherein the scene information comprises the number of lamps in the target outdoor area and area information of the target outdoor area;

[0120] In this step, the target outdoor area refers to a specific lighting environment where the LED high-power outdoor area lighting lamp is located, such as a stadium, a square, a road, a parking lot or a scenic area, etc., and the area, shape and use function of which may have great differences; the scene information comprises basic data such as the area of the area, the number of lamps, the installation height and the distribution position, which is input data for subsequent lighting calculation and strategy adjustment.

[0121] The purpose of this step is to provide accurate basic data for intelligent lighting control. By mastering the correspondence between the number of lamps and the area of the region, the coverage range of a single lamp, the average illumination requirement of the region, and the light source distribution density can be calculated, thereby providing a basis for brightness setting, zoning control, and power allocation. If accurate scene information is lacking, the subsequent generated brightness control instructions will not accurately match the on-site lighting requirements, resulting in energy waste or insufficient local illumination.

[0122] During implementation, various methods can be used to collect scene information. For newly built sites, the plan area and lamp arrangement data can be directly exported from construction drawings or design software; for existing places, the area size and lamp distribution can be obtained through manual mapping, laser ranging, or drone aerial photography. The collected data is formatted and stored in the control terminal as a basis for calculation. In this way, a digital description of the outdoor lighting space can be effectively established, providing a reliable foundation for subsequent brightness allocation, sensor response, and energy consumption evaluation.

[0123] S2, according to the scene information and the adjustment gear of the power selection component, obtaining a target output brightness;

[0124] Specifically, after obtaining the area and the number of lamps of the target outdoor region and other scene information, the target output brightness of the entire outdoor region or each lighting zone is determined by combining the current adjustment gear of the power selection component of each lamp (i.e., the actual power output or brightness level), through built-in algorithms or lookup parameter tables.

[0125] This determination process can refer to relevant national or industry lighting standards, combine the actual output capacity, distribution location, and functional requirements of each lamp, and intelligently allocate the target brightness value of each lamp to achieve dynamic adaptation and zoning adjustment of brightness in different use scenarios. In this way, the actual lighting requirements of the outdoor region can be met, and the lighting energy efficiency and energy-saving effect can be effectively improved.

[0126] S3, according to the target output brightness and the sensor information, controlling the LED high-power outdoor area lighting lamp to illuminate.

[0127] After determining the target brightness, real-time feedback signals of the sensor module are continuously received, and the operating state of the lamp is dynamically adjusted accordingly. The sensor module usually includes an ambient light sensor and an infrared motion sensor for detecting the intensity of external light and the activity of personnel in the area, respectively. In an embodiment, when the intensity of ambient light decreases below a set threshold or personnel activity is detected, the corresponding lamp is automatically enabled, and brightness matching is performed according to the target output brightness; if the ambient light is sufficient or there is no personnel activity for a long time, the brightness is gradually reduced or the lamp is turned off to achieve energy saving. This control method can realize flexible dimming according to the actual environment and use state, avoiding the problems of constant brightness or delayed response in traditional time control. The lamp can smoothly transition according to changes in light and people flow during actual operation, ensuring safety and comfort, and effectively prolonging the service life of the lamp and reducing energy waste. Through the comprehensive application of target output brightness and sensor information, the present application realizes the conversion from static configuration to dynamic control, enabling the lighting system to have adaptive response capability and energy efficiency optimization characteristics during long-term operation.

[0128] Preferably, the target output brightness is obtained according to the adjustment gear of the scene information and power selection component, including:

[0129] S21, according to the area information of the target outdoor area and the lamp distribution information, the corresponding lighting coverage area of each lamp is obtained;

[0130] In this step, based on the scene information obtained in the foregoing, the target outdoor area is spatially divided to determine the corresponding lighting coverage range of each LED high-power outdoor area lighting lamp in the area. The area information can be provided by electronic drawings, surveying and mapping data or installation layout drawings, and the lamp distribution information includes the installation position, elevation, irradiation direction and installation height of the lamp. By spatially correlating these two types of information, the lighting action area of each lamp can be established in a two-dimensional or three-dimensional coordinate system.

[0131] This division method can accurately identify the effective lighting boundary of each lamp, and the overlap or gap of light in the same area can be visually described. Unlike the traditional method of estimating the coverage range by average spacing, this method takes into account the actual optical characteristics and lamp layout, making the subsequent illumination distribution and brightness adjustment more consistent with the on-site lighting rules.

[0132] S22, according to the standard illuminance requirement of each lighting coverage area, the standard illuminance required by each lighting coverage area is obtained;

[0133] After the lighting coverage area is determined, the system determines the standard illuminance that each area should reach according to the use function, activity density or relevant standards of different areas. The standard illuminance value can refer to outdoor lighting design standards or industry specifications, such as different illuminance level requirements for areas such as main race areas of stadiums, main roads and parking areas.

[0134] In this way, the appropriate light target can be allocated for different functional areas. For example, a higher illumination level is set in the high-activity area or safety-sensitive area, while a relatively lower illumination value is set in the auxiliary area or passage area to balance the visual comfort and energy-saving effect. The standard illumination obtained in this way will serve as an important basis for subsequent brightness adjustment and power matching.

[0135] S23, adjust the gear of the power selection component to obtain the initial output brightness of each lamp;

[0136] In this step, the current power gear parameter of each lamp is read to determine its initial output brightness. The power selection component can be a mechanical switch, knob or electronic adjustment module for switching between different power levels to control the luminous flux output of the lamp.

[0137] By obtaining the current gear information, the system can calculate the corresponding initial brightness value within the rated power and maximum output range of the lamp. For example, when the lamp gear is at the medium gear, the system calculates the corresponding light intensity output according to the light efficiency curve of the lamp. This initial brightness value is not the final result, but a basic reference data for subsequent correction and balancing according to the standard illumination. In this way, the control starting point of each lamp can be ensured to match its actual hardware state, avoiding the situation that the power setting does not match the target illumination.

[0138] S24, adjust the initial output brightness according to the standard illumination of each lighting coverage area to obtain the intermediate output brightness;

[0139] In this step, the standard illumination requirement of each lighting coverage area is compared with the initial output brightness of the lamp, and the brightness output is corrected according to the difference. If the standard illumination of a certain area is higher than the illumination level corresponding to the current brightness, the output of the lamp is appropriately increased; otherwise, the brightness is correspondingly reduced. The adjustment range can be proportionally corrected according to the lamp type, light scattering angle or optical lens characteristics to ensure balanced illumination transition.

[0140] Through this process, the output of the lamp can be more in line with the functional requirements of the area, so as to obtain a set of intermediate brightness values within the standard illumination range. The intermediate output brightness represents the brightness state of each lamp after local optimization and is a transition parameter before the final lighting balance. The execution of this step enables the system to achieve preliminary illumination matching between different areas, reducing the phenomenon of local over-brightness or over-darkness.

[0141] S25, adjust the intermediate output brightness according to the brightness difference between the lighting coverage area and the adjacent lighting coverage area to obtain the target lighting brightness of each LED high-power outdoor area lighting lamp.

[0142] After the intermediate luminance calculation of each region is completed, the system further considers the luminance transition relationship between adjacent lighting coverage regions. Since outdoor lighting is mostly continuous distribution, if the illumination difference between adjacent regions is too large, it is easy to form bright-dark boundaries or visual discomfort. To avoid this situation, the system calculates the intermediate output luminance difference value of each lighting coverage region and its adjacent region, and according to the preset luminance difference allowable range, the output of the lamps and lanterns that exceed the part is fine-tuned.

[0143] For example, when the luminance difference of two adjacent regions exceeds the set threshold, the output of the high-light region will be moderately reduced according to the luminance weight of the adjacent region, and the output of the low-light region will be increased, so that the overall lighting distribution is smoother. Through this luminance coordination process, the target lighting luminance of each LED high-power outdoor regional lighting lamp is finally obtained, and a natural and visually continuous lighting effect between regions is realized. This method can significantly improve the uniformity and comfort of the overall lighting while ensuring that the local illuminance meets the standard. Preferably, the adjusting the intermediate output luminance according to the luminance difference value of the intermediate output luminance of the lighting coverage region and the adjacent lighting coverage region, to obtain the target lighting luminance of each LED high-power outdoor regional lighting lamp, comprises:

[0144] S251, according to the intermediate output luminance of each lighting coverage region, obtaining a set of luminance difference values of the lighting coverage region and all adjacent lighting coverage regions;

[0145] In this step, first, the intermediate output luminance of each lighting coverage region obtained in the previous stage is taken as the basic data, and the luminance difference value between each region and its surrounding adjacent region is calculated in turn. The adjacent region can be determined according to the actual light overlap relationship of the lamps and lanterns, for example, the region that overlaps with the light field boundary within the effective illumination radius of the lamps and lanterns is regarded as the adjacent region.

[0146] By calculating the set of luminance difference values, the illumination gradient distribution between different regions can be reflected, so as to identify which regions have a significant luminance difference. The execution of this step enables the system to establish a global contrast relationship of the luminance change between regions, providing data support for subsequent judgment of which regions need to be corrected.

[0147] S252, according to the set of luminance difference values and the preset luminance difference allowable range, obtaining the lighting coverage region that needs to be corrected, denoted as the region to be corrected;

[0148] After obtaining the set of luminance difference values, each difference value is compared with a preset luminance difference tolerance range. The luminance difference tolerance range is a threshold value set according to a visual uniformity standard or an empirical parameter, and represents the maximum luminance difference allowed between adjacent regions. For example, when the luminance difference between two adjacent regions exceeds the threshold value, it indicates that a clear light-dark boundary may be formed in vision.

[0149] When the luminance difference between a certain lighting coverage area and any of its adjacent regions exceeds the tolerance range, the region is identified as a region to be corrected. Through this screening process, uneven regions can be quickly located in the global lighting distribution, and only these regions are subjected to subsequent correction operations, thereby improving the overall operation efficiency and avoiding repeated adjustment of balanced regions.

[0150] S253, according to the luminance difference between the region to be corrected and its adjacent regions, obtaining a correction weight of the adjacent regions to the region to be corrected;

[0151] In this step, the correction weight is calculated based on the luminance difference between the region to be corrected and each adjacent region. The weight value reflects the degree of influence of the adjacent region on the region to be corrected. In an embodiment, the greater the luminance difference or the closer the distance between the adjacent regions, the higher the weight value.

[0152] In the calculation, the absolute value of the luminance difference and the light overlap ratio of the adjacent regions are considered comprehensively to determine the direction and amplitude of the correction. In this way, it can be identified which adjacent regions play a major role in the luminance unevenness of the region to be corrected, so as to give it a higher adjustment weight in the subsequent adjustment, making the overall correction more reasonable and more accurate in response.

[0153] S254, according to the correction weight, performing weighted adjustment on the intermediate output luminance of the region to be corrected to obtain a first corrected luminance;

[0154] After determining the correction weight, the system performs weighted calculation on the intermediate output luminance of the region to be corrected using the weight to obtain a first corrected luminance. Specifically, when the luminance of the region to be corrected is higher than that of its adjacent regions, the system appropriately reduces the output of the region according to the average luminance of the adjacent regions and the correction weight; when the luminance is low, the output level is increased to reduce the luminance difference.

[0155] The process of weighted adjustment is not a simple average, but a dynamic distribution according to the influence degree of each adjacent region, so that the adjustment result can both alleviate the local difference and not damage the overall illumination structure. After this correction, the luminance of the region to be corrected tends to be coordinated with the adjacent regions, forming a preliminary balanced lighting state.

[0156] S255, according to the first corrected luminance, the lower limit and the upper limit of the standard illuminance of the region to be corrected, performing boundary constraint to obtain a second corrected luminance;

[0157] The weighted adjusted brightness still needs to be limited within a reasonable illumination range to ensure compliance with lighting standard requirements. To this end, the system compares the first modified brightness with the upper and lower limits of the standard illumination of the region, and reduces the modified value when it exceeds the upper limit, and increases it when it is below the lower limit.

[0158] This boundary constraint ensures that the adjustment process will not cause insufficient or excessive brightness due to brightness coordination, so that the lamp output is always within a safe and comfortable illumination range. After this step, the obtained second modified brightness can be regarded as an intermediate balanced value that meets the standard constraint conditions, providing a stable basis for subsequent comprehensive brightness coordination.

[0159] S256、According to the difference between the second modified brightness and the intermediate output brightness of each adjacent lighting coverage region, obtain the brightness influence value of each adjacent lighting coverage region on the region to be modified;

[0160] After completing the boundary constraint, the brightness difference between the region to be modified and the adjacent region is calculated again, but this time using the second modified brightness as the reference. By comparing with the intermediate output brightness of each adjacent region, the influence value of each adjacent region on the current modified result can be obtained.

[0161] These influence values reflect the reverse effect of the modified brightness change on the surrounding regions, that is, when the adjustment of a region may cause illumination imbalance in adjacent regions, the system can perceive and quantify this chain reaction through these influence values, providing a basis for the next step of comprehensive balancing.

[0162] S257、According to the brightness influence value and the corresponding modification weight, obtain the total adjustment amount acting on the region to be modified;

[0163] This step integrates the aforementioned brightness influence values and the modification weights of each adjacent region to calculate the total adjustment amount acting on the region to be modified. The total adjustment amount represents the total modification amplitude that should be applied in the overall lighting system to achieve local balance.

[0164] During the calculation process, the weighted summation method can be used, so that regions with strong lighting influence occupy a higher proportion in the result. Through this method, collaborative adjustment between multiple regions can be achieved, so that the modification process is not limited to a single point, but considers the interaction of the overall light field, thereby preventing new brightness imbalance caused by local modification.

[0165] S258、According to the total adjustment amount, adjust the second modified brightness to obtain the final modified brightness of the region to be modified;

[0166] According to the total adjustment amount, the second corrected brightness is finally adjusted to obtain the final corrected brightness of the region. At this time, the adjustment range is usually small, mainly used to eliminate the slight deviation caused by the previous correction, and realize the global refinement balance of brightness.

[0167] After multiple iterations, the final corrected brightness tends to be stable, so that the brightness difference between adjacent regions is within the allowable range. The final corrected brightness not only reflects the compliance of the standard illuminance, but also takes into account the softness of the transition between regions, ensuring that the overall light field distribution is continuous and has no obvious bright-dark boundary.

[0168] S259, according to the final corrected brightness, obtaining the target lighting brightness of the LED high-power outdoor area lighting lamp corresponding to the region to be corrected.

[0169] Finally, the final corrected brightness of the region to be corrected is converted into the control parameter of the specific lamp, that is, the target lighting brightness. The control terminal generates a corresponding driving signal according to the target value to adjust the output power or PWM duty cycle of the LED lamp, so that its luminous intensity is consistent with the corrected brightness.

[0170] Through this process, the light intensity output by the lamp is consistent with the overall lighting distribution, and the illumination gradient of the entire outdoor area tends to be smooth, meeting the functional lighting requirements and having high visual uniformity and energy saving characteristics. After the process is completed, the system enters a stable running state, and the above correction process can be re-executed when the environment changes or the power level is adjusted, realizing dynamic balance closed-loop control.

[0171] Preferably, the method comprises:

[0172] S31, obtaining an ambient brightness value according to the ambient light intensity collected by the ambient light sensor;

[0173] In this step, the natural light intensity of the target outdoor area is collected in real time by the ambient light sensor arranged on the lamp housing or the control terminal. The ambient light sensor can be in the form of a photoresistor, a photodiode or a digital illumination sensor module, which can convert the external light intensity into an electrical signal, and then obtain the current ambient brightness value after processing by the control circuit.

[0174] The brightness value is in units of Lux, which reflects the overall light and dark state of the site under natural lighting conditions. Through real-time detection of the ambient brightness, the system can accurately judge whether artificial lighting is needed, avoiding the lamp from working inefficiently in the daytime or high-light environment, thereby realizing energy-saving control.

[0175] S32, obtaining the switch state of the LED high-power outdoor area lighting lamp according to the comparison result of the ambient brightness value and preset opening brightness threshold and closing brightness threshold;

[0176] After obtaining the ambient brightness value, it is compared with the preset opening brightness threshold and closing brightness threshold to determine whether the lamp needs to be turned on or off. The opening brightness threshold indicates that the lighting should be started when the ambient brightness is lower than this value, and the closing brightness threshold indicates that the lighting should be turned off when the ambient brightness is higher than this value. A certain hysteresis interval can be set between the two to prevent the lamp from frequently starting and stopping due to short-term brightness fluctuations.

[0177] Through this comparison process, the current switch state can be automatically determined. For example, when the natural light intensity decreases to below the opening threshold in the evening, the lamp automatically enters the working state; in the morning or when the weather turns sunny, the brightness increases above the closing threshold, and the system automatically turns off the lamp. This intelligent judgment based on ambient brightness makes the lighting response more in line with the changes in natural light, reducing manual intervention.

[0178] S33, when the switch state is on, obtaining the activity intensity level in the coverage area of each LED high-power outdoor area lighting lamp according to the personnel activity information collected by the infrared motion sensor;

[0179] When the system determines that the lamp is in the on state, the infrared motion sensor will be further used to detect the personnel activity in the lighting coverage area. The infrared sensor identifies motion events by sensing changes in infrared radiation emitted by the human body, and can output pulse signals or continuous signals. The control circuit calculates the activity intensity level of the coverage area by counting the number of detections per unit time, the duration of the motion and the signal amplitude.

[0180] The activity intensity level can be divided into multiple levels, such as "still", "low-frequency activity", "moderate activity" and "high-frequency activity", etc., to reflect the usage frequency or flow density of the area. By quantifying the activity intensity into level information, the system can provide more detailed control basis for subsequent brightness adjustment, so that the lighting output can change dynamically with the usage state of the site.

[0181] S34, adjusting the target output brightness of each LED high-power outdoor area lighting lamp according to the activity intensity level and the ambient brightness value;

[0182] In this step, the target output brightness of each lamp is adjusted in real time by combining the ambient brightness value and the activity intensity level. Ambient brightness mainly affects the overall lighting baseline, while activity intensity reflects the usage demand of the local area. The system can determine the brightness correction amplitude according to the comprehensive result of the two.

[0183] For example, when the ambient brightness is low and the activity intensity is high, the brightness of the corresponding lamp is increased to ensure visual clarity; when the activity intensity is low but people are still staying, the medium brightness is maintained to save energy; when the activity intensity is extremely low or the area is unoccupied, the brightness is gradually reduced or the lamp enters standby mode.

[0184] In addition, to prevent the brightness from changing too abruptly, a smooth adjustment curve can be set to gradually change the brightness of the lamp over time, thereby improving visual comfort and prolonging the life of the LED. In this way, the lighting output can be automatically optimized according to the real-time scene, realizing intelligent response of bright when needed and dark when not needed.

[0185] S35, controlling the LED high-power outdoor area lighting lamp to illuminate according to the adjusted target output brightness;

[0186] After completing the brightness adjustment, a corresponding control signal is generated according to the corrected target output brightness to drive the power module of each LED high-power outdoor area lighting lamp. The control method can be to adjust the output current of the constant current source, the PWM duty cycle or the output power of the constant voltage drive to realize continuous adjustable brightness change.

[0187] Through this process, each lamp can operate according to its independent target brightness output, thereby forming an adaptive illuminance distribution based on the environment and use state in the entire lighting area. Compared with the traditional centralized control mode, this step can realize differentiated adjustment of partition brightness, making the light energy distribution more in line with the actual use demand, while improving the overall energy efficiency and lighting quality.

[0188] S36, when the personnel state is no personnel present and the preset delay condition is met, controlling the LED high-power outdoor area lighting lamp to turn off.

[0189] To avoid frequent on-off due to short-time leaving or sensor detection delay, a preset delay condition is set in this step. When the infrared sensor does not detect personnel activity within a certain time, the system starts timing, and if the duration exceeds the set delay threshold (for example, 30 seconds or 1 minute), it is judged that the area is unoccupied, and a turn-off instruction is issued.

[0190] The delay strategy enables the lighting system to maintain convenience while minimizing invalid energy consumption. Especially in places where personnel frequently enter and exit or the ambient light changes quickly, this mechanism can effectively prevent the lamp from being frequently started and stopped due to false triggering or instantaneous obstruction, thereby improving the service life and control stability. Through this "delayed closing" control, the system realizes the balance between people, light and environment, taking into account energy saving and comfort.

[0191] Preferably, the adjustment of the target output brightness of each LED high-power outdoor area lighting lamp according to the activity intensity level and the ambient brightness value comprises:

[0192] S341、According to the activity intensity level in each lighting coverage area, the activity intensity distribution is obtained;

[0193] In this step, the system aggregates the activity intensity level information fed back by each infrared motion sensor to generate the activity intensity distribution of the entire target outdoor area. The activity intensity level of each lighting coverage area reflects the activity frequency or density of the personnel in the area.

[0194] Through spatial mapping, these level information can be corresponded to the illumination range of the lamps, thereby forming a two-dimensional distribution map reflecting the dynamics of the flow of people. The distribution can intuitively describe the heat of each area, which is an important basis for subsequent judgment of lighting key areas and dimming strategy.

[0195] S342、According to the activity intensity distribution, the activity intensity difference between each lighting coverage area is judged;

[0196] After obtaining the activity intensity distribution, the activity intensity difference between different lighting coverage areas is further calculated. Specifically, the difference between the intensity levels of adjacent or all areas can be compared to judge the overall difference. If the activity intensity of each area is close, it means that the overall use of the site is balanced; otherwise, there is a concentrated area of people flow.

[0197] The judgment result is used to determine the mode of the subsequent brightness adjustment strategy: when the activity difference is small, the system mainly adapts the overall illumination to the environment; when the difference is large, the local enhancement of the people flow concentrated area is needed. Through this process, the system can dynamically distinguish between "uniform lighting mode" and "zoned key lighting mode", and realize more accurate light energy distribution.

[0198] S343、When the activity intensity difference is less than a preset difference threshold, the target output brightness of each LED high-power outdoor area lighting lamp is adjusted according to the environmental brightness value;

[0199] When it is judged that the activity intensity difference of each coverage area is small, it means that the flow of people is relatively uniform, and the entire lighting scene does not need obvious regional brightness difference. In this case, the system takes the environmental brightness as the dominant factor to adjust the output brightness of all lamps as a whole.

[0200] For example, when the environmental brightness decreases, the system proportionally increases the brightness of each lamp; when the external light increases, the overall brightness output is reduced synchronously.

[0201] This adjustment mode makes the site lighting coordinate with the natural light environment, avoids visual discomfort or energy waste caused by sudden changes in light, and realizes dynamic and stable control of the overall brightness of the scene.

[0202] S344, when the activity intensity difference is greater than or equal to the preset difference threshold, taking the lighting coverage area corresponding to the activity intensity level as the hotspot area;

[0203] When the activity intensity difference of different areas is detected to be large, the area with the most concentrated activity is identified and marked as a hotspot area. This area usually corresponds to the area with the most dense flow of people and the most frequent activity, such as the center of a sports field, the core area of a square, or the main channel of a road.

[0204] In this way, the key lighting area can be quickly locked in, so as to preferentially allocate lighting resources to the area with the highest usage frequency, and realize "people-centered" intelligent lighting control. The identification of the hotspot area can be dynamically updated based on real-time activity data, so that the light intensity distribution of the lamp changes with the use of the scene.

[0205] S345, according to the activity intensity level of the hotspot area and the upper limit of the standard illuminance, the target output brightness of the corresponding LED high-power outdoor area lighting lamp is adjusted upwards;

[0206] After identifying the hotspot area, the promotion amplitude is determined according to the activity intensity level, and the brightness is adjusted upwards with reference to the upper limit of the standard illuminance of the area. The higher the activity intensity level, the higher the adjustment ratio, but it will not exceed the upper limit of the standard illuminance, so as to prevent over-brightness or glare.

[0207] This adjustment makes the hotspot area form a visual focus, providing sufficient illuminance for the high-frequency activity area, while maintaining lighting safety and comfort. By controlling the upper limit, the system can not only guarantee functional lighting, but also avoid high energy consumption, achieving a balance between brightness enhancement and energy efficiency.

[0208] S346, according to the spatial relationship between the hotspot area and the adjacent coverage area, the diffusion coefficient of the hotspot area to the adjacent area is obtained;

[0209] The brightness adjustment of the hotspot area will have a radiation effect on the adjacent area, in order to make the light field transition natural, the system calculates the diffusion coefficient of the hotspot area to the adjacent coverage area according to the spatial relationship between the hotspot area and the adjacent coverage area in this step.

[0210] The diffusion coefficient can be determined according to the geometric distance, illumination overlap area or lamp projection angle of the adjacent area. For example, when the center distance of two areas is close or the illumination overlap ratio is high, the diffusion coefficient is large; when the distance is far or the overlap is less, the coefficient is small.

[0211] This parameter is used to quantify the light spillover range of the hotspot area, so that the system can control the brightness adjustment amplitude of the adjacent area, thereby realizing the continuous transition of the brightness between areas.

[0212] In an embodiment, the step S346 further comprises:

[0213] S3461、According to the installation position and the lighting coverage range of the hotspot area and each adjacent coverage area, a spatial relationship parameter between the hotspot area and each adjacent coverage area is obtained, the spatial relationship parameter including a region center distance, an illuminance gradient direction angle, and a coverage overlap rate, for representing the geometric and optical correlation between adjacent areas;

[0214] In this step, the geometric boundary of the lighting coverage area of each LED high-power outdoor area lighting lamp is calculated according to the installation coordinates, the installation height, and the light-emitting angle of the LED high-power outdoor area lighting lamp. Through spatial matching of the boundary positions of the hotspot area and the adjacent area, the distance between the region centers (i.e., the region center distance) and the angle between the illumination distribution directions of the two areas (i.e., the illuminance gradient direction angle) can be obtained. In addition, by analyzing the isocline overlap range of the illuminance distribution, the coverage overlap rate is obtained, which is used to reflect the overlap degree of the two lighting areas in the light field. These spatial relationship parameters can accurately reflect the geometric characteristics and optical coupling relationship of the interaction of the lamps in space, and provide a quantitative basis for the adjustment of the lighting continuity.

[0215] S3462、According to the region center distance and the illuminance gradient direction angle, a distance attenuation factor for reflecting the distance attenuation law of illumination and a directionality compensation factor for reflecting the consistency of the main illumination direction and the diffusion direction of the lamp are obtained.

[0216] In this step, the distance attenuation factor is used to describe the law that the illumination intensity decreases with the increase of the distance between the areas. An exponential decay model or a piecewise linear decay model can be used for calculation, so that the farther the distance, the weaker the diffusion influence. The directionality compensation factor is calculated according to the illuminance gradient direction angle. For example, the consistency of the main illumination direction and the diffusion direction of the lamp is expressed by a cosine square function. When the adjacent areas are in the main illumination direction, the compensation coefficient is close to 1; when the deviation is large, the compensation coefficient is significantly reduced.

[0217] By considering both the distance and the direction, this step can more truly reflect the light field propagation characteristics, so that the diffusion influence is physically reasonable, and the situation of abnormally high illuminance in the non-main light area is avoided.

[0218] S3463、According to the coverage overlap rate, a lighting coupling factor between the hotspot area and the adjacent coverage area is obtained, the lighting coupling factor being used to reflect the spatial coincidence degree of the illumination distribution of the two areas.

[0219] The lighting coupling factor represents the light field overlap intensity of the two lighting areas, which can be calculated according to the ratio of the illuminance superposition area to the total coverage area. When the illumination distribution of the two areas is highly overlapped, the coupling factor is large, indicating that the illumination has a strong complementary relationship; when there is almost no overlap between the areas, the coupling factor tends to zero.

[0220] This parameter is used to compensate the fusion of neighborhood light in space, so that the diffusion adjustment is not only based on distance and direction, but also takes into account the actual overlap of light, thereby reducing the brightness mutation and improving the overall lighting uniformity in the case of multiple lamp parallel lighting.

[0221] S3464, according to the personnel activity direction information collected by the infrared motion sensor, the activity trend direction factor is obtained, which is used to reflect the dynamic influence of the moving direction of people flow on the diffusion direction of light.

[0222] In this step, the moving track direction of personnel activity extracted in the infrared motion sensor is matched with the spatial orientation of the hotspot area and its adjacent areas. When the moving direction of people flow is consistent with the direction of a certain adjacent area, the activity trend direction factor takes a higher value; if the directions are opposite, a lower value or a negative value is taken, so as to realize dynamic inhibition. By introducing this factor, the system can dynamically correct the diffusion direction of light in real time according to the dynamic people flow, so that the light enhancement area is consistent with the moving trend of people flow, thereby realizing the intelligent linkage effect of "light following people", and significantly improving the space utilization efficiency and energy consumption management accuracy.

[0223] S3465, according to the distance attenuation factor, the directionality compensation factor, the light coupling factor and the activity trend direction factor, the comprehensive diffusion intensity value of the hotspot area to each adjacent coverage area is obtained;

[0224] In this step, the four types of factors are weighted and calculated to obtain the comprehensive diffusion intensity value of the hotspot area to the adjacent area. The weight can be customized according to the type of on-site environment or application scene (such as a sports field, a parking lot or a square), so as to reflect the dominant role of different factors in different environments. For example, the weight of the directionality factor can be increased in an open site, and the proportion of the coupling factor can be increased in a dense area.

[0225] S3466, according to each comprehensive diffusion intensity value and a preset weight ratio, an initial diffusion coefficient is obtained.

[0226] S3467, the initial diffusion coefficient is normalized to obtain the final diffusion coefficient of the hotspot area to each adjacent coverage area.

[0227] In this step, the comprehensive diffusion intensity value of each adjacent area is proportionally mapped to the initial diffusion coefficient, and through normalization operation, the sum of all diffusion coefficients is 1, so as to ensure the overall balance of energy distribution. The normalized diffusion coefficient reflects the diffusion proportion of the hotspot area brightness to each adjacent area, which not only avoids local over-lighting, but also ensures the natural continuity of the light gradient. Through this processing, the final diffusion coefficient can be directly used for illumination correction, so that the system realizes smooth and gradual brightness transition effect, which significantly improves the lighting energy efficiency while meeting the visual comfort.

[0228] S347. Based on the diffusion coefficient, adjust the target output brightness of the coverage area adjacent to the hotspot area to obtain the transition brightness;

[0229] After obtaining the diffusion coefficient, the system proportionally diffuses the increased brightness of the hotspot area to adjacent coverage areas. For example, when the brightness of the hotspot area is increased by 20% and the diffusion coefficient with the adjacent area is 0.5, the brightness increase of the adjacent area is 10%.

[0230] In this way, adjacent areas will not be directly perceived as hotspots, but will receive a moderate increase in brightness, thus creating a natural brightness gradient in the vision, making the transition from the bright area to the surrounding area smoother for the human eye.

[0231] The generation of this transition brightness not only improves overall visual comfort, but also avoids obvious light-dark transitions between hot spots and surrounding areas.

[0232] S348. Based on the coverage area corresponding to the minimum activity intensity, the target output brightness of the corresponding high-power LED outdoor area lighting is reduced to the lower limit range of the standard illuminance.

[0233] At the same time, the brightness of areas with the lowest activity levels will be reduced. These areas are typically those with low usage frequency or temporarily unoccupied, such as the edges of the stands and backup passageways.

[0234] Based on the lower limit of the preset standard illuminance, the system reduces the brightness of such areas to the minimum illuminance value that still meets the requirements for safe walking or basic identification, thereby achieving energy-saving control.

[0235] This strategy of reducing brightness in low-intensity areas complements the strategy of increasing brightness in hot spots, resulting in a more rational distribution of light energy and helping to reduce overall energy consumption while ensuring functionality.

[0236] S349. Smooth the brightness difference between hotspot areas, adjacent coverage areas and coverage areas corresponding to minimum activity intensity to adjust the target output brightness of each high-power LED outdoor area lighting.

[0237] After the aforementioned increases and decreases, some differences in brightness may still exist between different areas. This step achieves final equilibrium in the illumination distribution by smoothly correcting the brightness differences between hot spots, adjacent coverage areas, and low-intensity areas. The correction process can employ linear interpolation or proportional transition to ensure that brightness changes continuously decrease spatially, avoiding obvious boundaries between light and dark areas. Ultimately, the target output brightness of each LED fixture forms a gradually transitioning illumination distribution pattern from the center to the periphery across the entire field, highlighting key activities while maintaining overall visual comfort and illumination uniformity.

[0238] Through the setting of the steps S341 to S349, the application realizes the spatial adaptive brightness adjustment based on the activity intensity distribution, so that the lighting system can intelligently distribute light energy according to the human flow dynamics and the ambient light changes. When the activity difference of different areas is small, the system mainly adjusts the overall brightness according to the ambient brightness; when the difference is large, the hot spot area is automatically identified and the brightness is increased, the adjacent area is gradually supplemented according to the diffusion coefficient, the brightness of the low activity area is reduced, and the smooth correction is performed to eliminate the light and dark mutation between areas. Therefore, not only the sufficient lighting and safety of the dense human flow area are ensured, but also the energy saving and visual comfort of the peripheral area are considered, so that the overall light field distribution is more natural and the energy efficiency is higher, and the intelligent level and use experience of the lighting system are significantly improved.

[0239] In summary, the LED high-power outdoor area lighting lamp and the control method thereof provided by the embodiment of the application realize the modularization of the lamp structure, the convenience of installation and maintenance, and the intelligent adaptive adjustment of lighting in various scenes by integrating the detachable LED light-emitting module, the multi-gear power selection assembly, the multiple types of sensors such as the ambient light and personnel sensors, and the intelligent control circuit.

[0240] The scheme can dynamically determine the optimal target lighting brightness according to the key scene information such as the actual area of the outdoor scene, the number of lamps, the personnel activity state, and the ambient light intensity, and automatically turn on, off or adjust the output of each lamp as needed, thereby realizing efficient and uniform, energy-saving and intelligent outdoor area lighting.

[0241] Therefore, the application not only effectively improves the intelligent level and use experience of outdoor area lighting, significantly reduces the overall energy consumption and operation and maintenance cost, but also enhances the reliability and adaptability of the system, meets the diversified application requirements, and realizes safe, comfortable, economical and environmentally friendly lighting effect.
