Description

Technical Field

[0001] This invention belongs to the field of underground space utilization, and specifically relates to a rhythmic lighting device, control system, control method and construction method. Background Technology

[0002] To achieve a dual improvement in both the wartime preparedness benefits and the needs of the people, the renovation and reuse of existing underground civil defense projects is increasingly common. Early wartime underground civil defense projects emphasized "connectivity," meaning connecting multiple shelters, command posts, and supply depots through long underground passages to form "underground corridors" or "underground cities." The main spatial carriers for the renovation and reuse of existing underground civil defense projects are the shelters, command posts, and supply depots, which are used for underground parking lots, cultural and sports activity spaces, underground storage, and laboratories, while the underground passages are primarily retained for passageway purposes.

[0003] Underground spaces are relatively dark, enclosed, and poorly ventilated. Deep underground spaces (such as below 50m) lack natural light and contact with the natural environment, often giving people a negative and depressing feeling. At present, the lighting of long underground passages still mainly uses high-power lamps with large spacing and constant illuminance, resulting in a high proportion of lighting energy consumption. Moreover, constant lighting can easily cause circadian rhythm disorders, affecting people's comfort and health.

[0004] Therefore, it is essential to provide a lighting control solution that is suitable for enclosed underground linear spaces and takes into account both energy-saving and visual requirements. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention provides a rhythmic lighting device, control system, and control method suitable for enclosed underground linear spaces that balances energy conservation and visual appeal.

[0006] The technical solution of the present invention is: a rhythmic lighting device, comprising:

[0007] A lamp mounting bracket has two side plates that are connected to each other, and a mirror panel is fixed between the two side plates. The mirror panel is provided with a mounting groove.

[0008] The variable angle lamp housing has an arc-shaped ring plate, with bow-shaped sealing plates at both ends of the ring plate, and a U-shaped curved plate inside the ring plate; the variable angle lamp housing is rotatably disposed inside the mounting slot around its axis, and the lamp mounting bracket is also provided with an angle adjustment component for driving the variable angle lamp housing to rotate.

[0009] The lamp cluster module is disposed within the variable angle lamp compartment. The lamp cluster module includes a housing, and the interior of the housing is divided into two independent chambers by a partition. The first chamber is provided with an LED lamp bead group, and a light-transmitting window is provided on the side facing the lighting direction. The second chamber is a primary phase change heat storage material chamber filled with phase change heat storage material.

[0010] A secondary phase change heat storage material chamber is provided in the internal space of the lamp mounting bracket. A heat exchange coil is provided inside the chamber, and phase change heat storage material is filled between the heat exchange coil and the inner wall of the secondary phase change heat storage material chamber.

[0011] A capillary heat exchanger assembly includes a capillary heat exchanger and a pumping component. The capillary heat exchanger, the pumping component, and the heat exchange coil are connected by pipelines to form a closed heat exchange loop, which is filled with a heat-conducting medium.

[0012] Furthermore, an arc-shaped rack is provided on the outer side of the ring plate along its circumference, and the angle adjustment component has a gear that meshes with the rack and an angle adjustment motor that drives the gear to rotate. The angle adjustment motor is mounted on the lamp mounting bracket.

[0013] The rhythmic lighting control system includes an integrated control platform, on which are connected the following:

[0014] Multiple rhythmic lighting devices are arranged along a linear space, which is divided into multiple independently controllable lighting segments;

[0015] An external light sensing and stepped dimming control module is used to acquire the optical parameters of external natural light and adjust the lighting output of the rhythmic lighting device in the entrance area based on the optical parameters and preset rhythmic lighting target parameters.

[0016] The step-by-step rhythmic lighting control module monitors personnel movement and, in response to personnel movement, controls the switching on or brightness adjustment of the corresponding segmented rhythmic lighting devices.

[0017] The waste heat recovery and reuse control module is used to monitor the temperature of the phase change heat storage unit that is thermally connected to the lamp cluster module, and to control the start of the heat recovery cycle when the temperature reaches the threshold.

[0018] Furthermore, the external light sensing and stepped dimming control module is specifically used for:

[0019] Real-time monitoring of external natural light illuminance H1 and color temperature W1;

[0020] Based on the preset calculation model, and combined with the preset illuminance H2 and color temperature W2 of the current time period of the rhythmic lighting curve, calculate the step transition parameter Hx of illuminance and the step transition parameter Wx of color temperature within a transition distance L1.

[0021] Based on Hx and Wx, the illuminance and color temperature of the lamp cluster modules within the L1 range are controlled, so that the entrance area lighting can be adaptively adjusted according to changes in external natural light.

[0022] Furthermore, the step-rhythmic lighting control module specifically includes:

[0023] The personnel sensing unit includes personnel sensors installed in each segment to detect whether personnel have entered the corresponding segment.

[0024] The personnel following control unit is used to respond to personnel detection by personnel sensors to control the rhythmic lighting devices in at least one segment in front of and at least one segment behind the personnel to operate according to the rhythmic lighting target parameters, and to control the rhythmic lighting devices in the remaining segments to operate in energy-saving mode.

[0025] Furthermore, the personnel following control unit is specifically configured as follows:

[0026] Maintain the rhythmic lighting devices within a range of 2 times S1 in front of and 1 times S1 behind the personnel in normal working condition.

[0027] Furthermore, the rhythmic lighting control system also includes a node space linkage control unit and an isolation door connecting the linear space and the node space;

[0028] The isolation door is equipped with an access control system;

[0029] The access control system is used to report personnel passage information when personnel pass through;

[0030] The node space linkage control unit is configured as follows:

[0031] When personnel enter the node space from the linear space through the isolation door, if it is determined that all personnel have entered based on the personnel access information, the linear space rhythmic lighting device is controlled to start delayed lighting, and then turns off or dims after a set duration; if it is determined that not all personnel have entered, the linear space rhythmic lighting device is controlled to maintain its original state.

[0032] When personnel return from the node space to the linear space through the isolation door, the rhythmic lighting device near the linear space is turned on or brightened to the target parameters of rhythmic lighting.

[0033] Furthermore, the waste heat recovery and reuse control module is specifically used for:

[0034] The temperature of the phase change thermal storage material is monitored in real time by temperature sensors installed in the primary phase change thermal storage material chamber and / or the secondary phase change thermal storage material chamber.

[0035] When the temperature of the secondary phase change thermal storage material chamber reaches the upper limit temperature of its phase change thermal storage material, the pumping component is activated to drive the circulation of the heat transfer medium, transferring the heat from the secondary phase change thermal storage material chamber to the hot water collection pipe or fresh air duct.

[0036] The control method for a rhythmic lighting control system includes the following steps:

[0037] Step 1, External light adaptive adjustment: Obtain the optical parameters of external natural light, and adjust the lighting output of the rhythmic lighting device in the entrance area based on the optical parameters and the preset rhythmic lighting target parameters;

[0038] Step 2, Personnel-following lighting: Divide the lighting area into multiple segments, monitor personnel movement, and control the switching on or brightness adjustment of the corresponding segment's rhythmic lighting devices in response to personnel movement;

[0039] Step 3, Waste heat recovery control: Monitor the temperature of the phase change heat storage unit that is thermally connected to the rhythmic lighting device, and control the start of the heat recovery cycle in response to the temperature reaching a threshold.

This design recovers and converts the energy dissipated in the form of waste heat in the traditional lighting system into a zero-carbon heat source with usable quality and capable of spatiotemporal transfer through the heat storage and release process of the phase change material. On the one hand, this fundamentally improves the heat dissipation performance of the lamp and ensures the luminous efficacy and lifespan. On the other hand, it provides a key technical path for realizing the energy self-circulation and low-carbon operation and maintenance of underground linear engineering.

[0049] (2) Rhythmic lighting control system and control method: By setting the preset rhythmic lighting target parameters, the illuminance and color temperature of the space are dynamically adjusted to simulate the changes in natural light, which helps to regulate the biological clock of users, improve psychological state and sleep quality, especially for underground spaces lacking natural light; The external light adaptive adjustment function at the entrance realizes a seamless and smooth connection between external natural light and internal artificial light, avoiding visual discomfort and safety hazards caused by drastic changes in light, and improving the comfort and safety of space use.

Terms such as "upper," "lower," "left," and "right" are used only to indicate relative positional relationships; when the absolute position of the described object changes, the relative positional relationship may also change accordingly.

[0062] like Figures 1 to 5 As shown, a rhythmic lighting device is disclosed, comprising:

[0063] The lamp mounting bracket 1 has two side plates 11 connected to each other, and a mirror panel 12 is fixed between the two side plates. The mirror panel 12 is provided with a mounting groove 13.

[0064] The variable angle lamp housing 2 has an arc-shaped ring plate 21, and both ends of the ring plate 21 are provided with bow-shaped sealing plates 22. The inside of the ring plate 21 is provided with a U-shaped bent plate 23. The variable angle lamp housing 2 is rotatably disposed inside the mounting groove 13 around its axis. The lamp mounting bracket 1 is also provided with an angle adjustment component for driving the variable angle lamp housing 2 to rotate.

[0065] The lamp cluster module 3 is disposed within the variable angle lamp compartment 2. The lamp cluster module 3 includes a housing 31, the interior of which is divided into two independent chambers by a partition 32. The first chamber is provided with an LED lamp bead group 34, and a light-transmitting window is provided on the side facing the lighting direction. The second chamber is a primary phase change heat storage material compartment 33 filled with phase change heat storage material.

[0066] A secondary phase change heat storage material chamber 4 is arranged in the internal space of the lamp mounting bracket 1. A heat exchange coil 41 is arranged inside the chamber, and phase change heat storage material is filled between the heat exchange coil 41 and the inner wall of the secondary phase change heat storage material chamber 4.

[0067] The capillary heat exchange assembly 5 includes a capillary heat exchanger 51 and a pumping component 52. The capillary heat exchanger 51, the pumping component 52 and the heat exchange coil 41 are connected by pipelines to form a closed heat exchange loop, and the heat exchange loop is filled with a heat-conducting medium.

[0068] In the above embodiment, the heat generated by the LED bead group 34 is first instantaneously absorbed by the primary phase change heat storage material chamber 33; subsequently, the heat is transferred to the secondary phase change heat storage material chamber 4 through the heat-conducting copper pipe loop; finally, when the temperature of the secondary chamber reaches the upper limit, the capillary network heat exchange component 5 is activated to transport the heat to the external heat utilization system; the rhythmic lighting device integrates the primary and secondary phase change heat storage material chambers. This design recovers and converts the energy dissipated in the form of waste heat in traditional lighting systems into a zero-carbon heat source with usable quality and capable of spatiotemporal transfer through the heat storage and release process of the phase change material; on the one hand, this fundamentally improves the heat dissipation performance of the lamps, ensuring luminous efficacy and lifespan; on the other hand, it provides a key technical path for realizing energy self-circulation and low-carbon operation and maintenance of underground linear engineering.

[0069] In some embodiments, the lamp mounting bracket 1 is made of aluminum alloy and the standard length is considered to be 1.0m; the two ends of the lamp mounting bracket 1 are fixedly connected by the ends of the two side plates 11 through the irregular plate; the lamp mounting bracket 1 is provided with a battery compartment 14 inside, and a battery is provided inside the battery compartment 14; the battery compartment 14 is made of sheet metal welded together, and an embedded hanging groove 15 is provided on one side of the battery compartment 14.

[0070] As a specific embodiment of the angle adjustment component in the above embodiments, an arc-shaped rack 24 is provided on the outer side of the ring plate 21 along its circumference. The angle adjustment component has a gear 6 that meshes with the rack 24 and an angle adjustment motor that drives the gear 6 to rotate. The angle adjustment motor is mounted on the lamp mounting bracket 1. The angle adjustment motor drives the gear 6 to rotate, and the gear 6 transmits power with the rack 24, causing the variable angle lamp housing 2 to be tilted within a certain range. Specifically, a rib is fixedly provided in the middle of the lamp mounting bracket 1 to provide support for the angle adjustment motor. The opening width of the U-shaped bent plate 23 is the same as the opening width of the ring plate 21. The two sides of the U-shaped bent plate 23 are designed to bulge slightly inward to provide clamping force on the lamp cluster module 3. Bow-shaped sealing plates 22 are fixedly provided at both ends of the ring plate 21, and the bow-shaped sealing plates 22 are rotatably connected to the irregular plates at both ends of the lamp mounting bracket 1.

[0071] In some embodiments, the outer shell 31 of the lamp cluster module 3 is made of aluminum profile, and heat dissipation fins are provided on the partition 32. The heat dissipation fins can enhance the heat dissipation of the LED lamp bead group 34 and increase the heat exchange area of ​​the phase change heat storage material. A heat-conducting copper pipe is installed in the primary phase change heat storage material chamber 33, which is connected to the heat exchange coil 41 of the secondary phase change heat storage material chamber 4 to form a loop. The loop is filled with ethylene glycol solution as a heat-conducting medium. The primary phase change heat storage material chamber 33 is filled with phase change heat storage material, such as paraffin-expanded graphite composite phase change heat storage material. The primary phase change heat storage material chamber 33 has an built-in NTC thermistor for monitoring the temperature change of the phase change heat storage material. The side plate of the aluminum profile outer shell 31 is designed to be slightly concave inward to facilitate insertion into the variable angle lamp chamber 2.

[0072] The LED bead group 34 has two implementation schemes: Scheme 1, the LED bead group 34 uses only rhythmic lighting beads, which can be used for rhythmic lighting scenarios by adjusting the illuminance and color temperature; Scheme 2, the LED bead group 34 adopts a combination of rhythmic lighting beads and plant lighting beads, wherein the spectrum of the plant lighting beads covers 660nm of red light, 450nm of blue light and 730nm of far-red light, and can intelligently switch between rhythmic lighting mode and plant lighting mode by time-sharing control or receiving external control signals.

[0073] In some embodiments, the secondary phase change thermal storage material chamber 4 is composed of a seamless aluminum alloy round or square tube, sealed at both ends, with a copper heat exchange coil 41 installed inside; the phase change thermal storage material inside the secondary phase change thermal storage material chamber 4 is used to receive the heat transfer from the primary phase change thermal storage material chamber 33; the phase change thermal storage material filling the space between the heat exchange coil 41 and the inner wall of the secondary phase change thermal storage material chamber 4 can be a paraffin-expanded graphite composite phase change thermal storage material; the secondary phase change thermal storage material chamber 4 has a built-in NTC thermistor for monitoring the temperature change of the phase change thermal storage material.

[0074] In some embodiments, the capillary heat exchanger 51 is a polypropylene or stainless steel capillary heat exchanger with a diameter of 3 to 5 mm; the inlet and outlet water ends of the capillary heat exchange assembly 5 are connected to the inlet and outlet water ends of the heat exchange coil 41 in the secondary phase change heat storage material silo 4; so that the capillary heat exchanger 51, the pumping component 52 and the heat exchange coil 41 form a loop, and the loop is filled with ethylene glycol solution as the heat transfer medium.

[0075] During implementation, the capillary heat exchanger 51 is installed on the inner wall surface of the hot water collection pipe or the fresh air duct. The heat transfer medium is driven to circulate through the pumping component 52, so as to transfer the heat of the secondary phase change heat storage material silo 4 to the hot water collection pipe or the fresh air duct. By heating the fluid in the hot water collection pipe, the heat can be transferred to the next stage heat storage tank for heating the entrance area of ​​the civil defense tunnel to avoid excessive temperature difference between the inside and outside of the tunnel, which would cause fogging at the tunnel entrance. By preheating the fresh air in the fresh air duct, the temperature of the tunnel wall is increased, and the condensation on the tunnel wall is suppressed.

[0076] In some embodiments, such as Figure 9 As shown, a rhythmic lighting control system is disclosed, including an integrated control platform, on which are connected:

[0077] Multiple rhythmic lighting devices are arranged along a linear space, which is divided into multiple independently controllable lighting segments;

[0078] An external light sensing and stepped dimming control module is used to acquire the optical parameters of external natural light and adjust the lighting output of the rhythmic lighting device in the entrance area based on the optical parameters and preset rhythmic lighting target parameters.

[0079] The step-by-step rhythmic lighting control module monitors personnel movement and, in response to personnel movement, controls the switching on or brightness adjustment of the corresponding segmented rhythmic lighting devices.

[0080] The waste heat recovery and reuse control module is used to monitor the temperature of the phase change heat storage unit that is thermally connected to the lamp cluster module, and to control the start of the heat recovery cycle when the temperature reaches the threshold.

[0081] The rhythmic lighting control system in the above embodiments dynamically adjusts the illuminance and color temperature of the space through preset rhythmic lighting target parameters, simulating changes in natural light. This helps regulate the biological clock of users, improve their psychological state and sleep quality, and is especially important for underground spaces lacking natural light. The adaptive adjustment function of external light at the entrance achieves a seamless and smooth connection between external natural light and internal artificial light, avoiding visual discomfort and safety hazards caused by drastic changes in lighting, and improving the comfort and safety of space use.

[0082] Specifically, such as Figure 8 As shown, the underground linear space is divided into n segments, N1, N2, N3, ..., Nx, ..., Nn, with the rhythmic lighting devices within the length S1 range as a group. Each segment can receive control commands and be controlled independently. Infrared sensors, M1, M2, M3, ..., Mx, ..., Mn, are installed every S1 length inside the underground linear space.

[0083] In some embodiments, the external light sensing and stepped dimming control module is specifically used for:

[0084] Real-time monitoring of external natural light illuminance H1 and color temperature W1;

[0085] Based on the preset calculation model, and combined with the preset illuminance H2 and color temperature W2 of the current time period of the rhythmic lighting curve, calculate the step transition parameter Hx of illuminance and the step transition parameter Wx of color temperature within a transition distance L1.

[0086] Based on Hx and Wx, the illuminance and color temperature of the lamp cluster modules within the L1 range are controlled, so that the entrance area lighting can be adaptively adjusted according to changes in external natural light.

[0087] Specifically, the external light sensing and stepped dimming control module installs a light intensity monitoring sensor outside the entrance of the underground linear space to monitor the illuminance H1 and color temperature W1 of the external natural light in real time. After receiving the data, the external light sensing and stepped dimming control module calculates the stepped gradient parameters Hx of the illuminance and Wx of the color temperature within a distance L1 based on the preset calculation model and the preset illuminance H2 and color temperature W2 of the rhythmic lighting curve of the underground linear space for the current period. It then controls the illuminance and color temperature of the rhythmic lighting device within the L1 range, so as to realize the adaptive adjustment of the lighting in the entrance area of ​​the underground linear space according to the changes in the brightness of the external natural light, season and weather.

[0088] Furthermore, since on sunny days, especially in summer, the sun can cause the illuminance of external natural light to be too high, exceeding the upper limit of artificial lighting, this embodiment provides two solutions: one is to use the peak value Hm of artificial lighting as the illuminance of the starting rhythmic lighting device at the entrance after the external natural light illuminance is detected to exceed a certain level; the other is to build a shading structure outside the entrance, with the top panel being opaque or partially translucent and the side panels being tempered glass.

[0089] In some embodiments, the step-rhythmic lighting control module specifically includes:

[0090] The personnel sensing unit includes personnel sensors installed in each segment to detect whether personnel have entered the corresponding segment.

[0091] The personnel following control unit is used to respond to personnel detection by personnel sensors to control the rhythmic lighting devices in at least one segment in front of and at least one segment behind the personnel to operate according to the rhythmic lighting target parameters, and to control the rhythmic lighting devices in the remaining segments to operate in energy-saving mode.

[0092] In some embodiments, the personnel following control unit is configured to:

[0093] Maintain the rhythmic lighting devices within a range of 2 times S1 in front of and 1 times S1 behind the personnel in normal working condition.

[0094] Specifically, the personnel sensor is an infrared sensor. Upon entering the underground linear space, the number of personnel (R1) must first be entered into the access control system. During movement, when the infrared sensor detects a person, it sends a signal to the system's step-by-step rhythmic lighting control module, which in turn sends a command to the corresponding segment Nx via the integrated control platform. The rhythmic lighting devices in segments N1 and N2, which are adjacent to the entrance L1 of the underground linear space and extend for twice the length S1, are in normal working order. When the infrared sensor M1 detects a person, segment N3 recovers from its lowest illuminance to the preset illuminance H2 for the current time period under rhythmic lighting conditions. When the infrared sensor M2 detects a person... When N4 segment recovers from the lowest illuminance to the preset illuminance H2 of the current period under rhythmic lighting, when infrared sensor M3 detects a person, N5 segment recovers from the lowest illuminance to the preset illuminance H2 of the current period under rhythmic lighting; when infrared sensor M4 detects a person, N6 segment recovers from the lowest illuminance to the preset illuminance H2 of the current period under rhythmic lighting, and N3 segment recovers to the lowest illuminance; when infrared sensor Mx (excluding M1, M2, and M3) detects a person, N(x+2) recovers from the lowest illuminance to the preset illuminance H2 of the current period under rhythmic lighting, and N(x-1) recovers to the lowest illuminance.

[0095] In some embodiments, the rhythmic lighting control system further includes a node space linkage control unit and an isolation door connecting the linear space and the node space;

[0096] The isolation door is equipped with an access control system;

[0097] The access control system is used to report personnel passage information when personnel pass through;

[0098] The node space linkage control unit is configured as follows:

[0099] When personnel enter the node space from the linear space through the isolation door, if it is determined that all personnel have entered based on the personnel access information, the linear space rhythmic lighting device is controlled to start delayed lighting, and then turns off or dims after a set duration; if it is determined that not all personnel have entered, the linear space rhythmic lighting device is controlled to maintain its original state.

[0100] When personnel return from the node space to the linear space through the isolation door, the rhythmic lighting device near the linear space is turned on or brightened to the target parameters of rhythmic lighting.

[0101] In some embodiments, it is determined whether all personnel have entered or left the node space by comparing the number of personnel entering the linear space R1, the number of personnel entering the node space R2, and the number of personnel leaving the node space R3.

[0102] As a specific implementation of the above embodiments, in the case of multiple node spaces (J1, J2, J3, ..., Jx, ..., Jn) connected in series through an underground linear space, when personnel leave the underground linear space and enter the adjacent node space Jx, they input the number of personnel entering the node space R2 into the access control system of the isolation door. If R2 equals R1, the access control system sends information to the integrated control platform, and the rhythmic lighting device near node space Jx will activate delay control, automatically restoring to the minimum illuminance after a set duration. If R2 is less than R1, the original state is maintained. When personnel leave node space Jx and enter the underground linear space, they still need to input the number of personnel leaving R3 into the access control system of the isolation door. The access control system sends information to the node space linkage control unit, and the rhythmic lighting device near node space Jx will restore to the preset illuminance H2 of the current time period under the rhythmic lighting state.

[0103] In some embodiments, the waste heat recovery and reuse management module is specifically used for:

[0104] The temperature of the phase change thermal storage material is monitored in real time by temperature sensors installed in the primary phase change thermal storage material chamber and / or the secondary phase change thermal storage material chamber.

[0105] When the temperature of the secondary phase change thermal storage material chamber reaches the upper limit temperature of its phase change thermal storage material, the pumping component is activated to drive the circulation of the heat transfer medium, transferring the heat from the secondary phase change thermal storage material chamber to the hot water collection pipe or fresh air duct.

[0106] In some embodiments, a control method for a rhythmic lighting control system is disclosed, comprising the following steps:

[0107] Step 1, External light adaptive adjustment: Obtain the optical parameters of external natural light, and adjust the lighting output of the rhythmic lighting device in the entrance area based on the optical parameters and the preset rhythmic lighting target parameters;

[0108] Step 2, Personnel-following lighting: Divide the lighting area into multiple segments, monitor personnel movement, and control the switching on or brightness adjustment of the corresponding segment's rhythmic lighting devices in response to personnel movement;

[0109] Step 3, Waste heat recovery control: Monitor the temperature of the phase change heat storage unit that is thermally connected to the rhythmic lighting device, and control the start of the heat recovery cycle in response to the temperature reaching a threshold.

[0110] In some embodiments, a method for constructing a rhythmic lighting control system is disclosed, comprising the following steps:

[0111] The rhythmic lighting control system described in any of the above embodiments is adopted;

[0112] Install a light sensor at the entrance of the linear space;

[0113] Heat recovery pipes containing capillary network heat exchangers are installed on both sides of the linear space.

[0114] Install rhythmic lighting devices on both sides of the linear space;

[0115] Install external light sensing and stepped dimming control modules, step rhythm lighting control modules, waste heat recovery and reuse management modules, and an integrated control platform to conduct system commissioning;

[0116] Adjust the illumination angle of the rhythmic lighting device and verify it through illuminance measurement and uniformity calculation until the preset lighting uniformity standard is met.

[0117] The following engineering case will further illustrate the construction method of the rhythmic lighting control system in the above embodiments.

[0118] (1) Taking the renovation of an old underground civil defense project as an example, the length of the main passage of the underground linear space is considered to be 300m, and there are 5 side chambers as node spaces. The construction of step-by-step rhythmic lighting environment is carried out.

[0119] (2) Use professional software to simulate the illuminance of the internal space of the underground civil defense project, set the chamber size, reflectivity, lamp parameters (power, luminous flux, light distribution curve, etc.), lamp installation position, adjust the angle and spacing, observe the illuminance distribution diagram and uniformity value, and determine the design installation height, spacing and angle of the rhythmic lighting device.

[0120] (3) A sunshade structure is built at the entrance of the underground civil defense project. The top plate is opaque or partially transparent, the side plates are made of tempered glass, and a light intensity monitoring sensor is installed inside the sunshade structure.

[0121] (4) Figure 6 and 7 As shown, hot water collection pipes or fresh air ducts 200 with built-in capillary heat exchangers 51 are installed on both sides of the main passage of the underground civil defense project; if the hot water collection pipe scheme is adopted, the hot water collection pipe also needs to be connected to the next-level heat storage tank.

[0125] (8) Control the variable angle lamp housings of each lamp to rotate to the designed installation angle through the integrated control platform. Select a typical section (such as the entrance, middle section, and exit) inside the main passage of the underground civil defense project, and use a lux meter to measure the illuminance at grid points 1.5 meters above the ground. Calculate U0 (minimum illuminance / average illuminance) and U1 (minimum illuminance / maximum illuminance). If U0≥0.4 and U1≥0.6 are not satisfied, fine-tune the variable angle lamp housings and continue measuring until the optimal installation angle that satisfies U0≥0.4 and U1≥0.6 is determined. Afterward, automatically control the variable angle lamp housings of each rhythmic lighting device 100 to rotate to the optimal installation angle through the integrated control platform.

[0126] In the above embodiments, the construction method of the rhythmic lighting control system ensures uniform light distribution throughout the space through illuminance simulation and fine-tuning of variable-angle lamp compartments, effectively avoiding problems such as localized darkness or glare.
