Description

Technology Field

[0001] The present invention relates to an underwater ecosystem protection type light pollution reduction smart panel and system for reducing light pollution affecting residential areas or ecosystems by reducing light pollution caused by lighting, thereby protecting residential areas, ecosystems, aquatic organisms, and the underwater environment. Background Technology

[0003] Smart panel systems are devices designed to provide lighting to work or activity areas in nighttime environments and are used in various settings such as construction sites, work zones, ports, and fish farms. Smart panel systems typically consist of multiple interconnected panels that illuminate the surrounding areas of workers or moving objects through lighting devices equipped on each panel.

[0004] However, these smart panel systems have a problem in that upward and leakage light causes light pollution when used at night. In particular, high-output lighting that continuously illuminates a wide area has an unnecessary impact on surrounding residential areas or ecosystems, and in nighttime work environments, glare reduces the visibility of workers. Additionally, there is a limitation in that energy is consumed unnecessarily because the entire area is continuously illuminated regardless of activity.

[0005] To address this, methods such as applying shading structures to restrict the direction of illumination or reducing lighting brightness have been proposed. However, these methods have the disadvantage of lowering worker safety and visibility by merely limiting the illumination range or reducing the total light intensity. Furthermore, there are limitations, such as light pollution in the surrounding area caused by the continuous illumination of a specific area with a fixed direction, and significant unnecessary energy consumption.

[0006] Accordingly, there is an increasing demand for eco-friendly smart panels and control systems capable of reducing unnecessary energy consumption and mitigating light pollution by selectively irradiating areas where movement occurs. This invention aims to contribute to the development of measures to reduce environmental impact by providing a light pollution reduction smart panel system that mitigates light pollution affecting surrounding residential areas or ecosystems.

The embodiments described and illustrated herein also include their complementary embodiments. Throughout the specification, parts indicated by the same reference numeral represent the same components.

[0022] The present invention relates to a smart panel system, and more specifically to a light pollution reduction smart panel system that protects the underwater ecosystem and can reduce light pollution and unnecessary energy.

[0023] Specifically, the smart panel system of the present invention has a cover formed on the upper part of the panel, and a lighting module is disposed on the lower surface of the cover to block upward light and leakage light.

[0024] In addition, the lighting and illumination direction of the lighting module are controlled based on time data stored in the control device and signals from the motion sensor, thereby illuminating light into an activity area where movement is detected at night. Accordingly, the light pollution reduction smart panel system of the present invention has the effect of preventing light pollution and saving energy.

[0025] Hereinafter, the light pollution reduction smart panel system of the present invention will be described in detail.

[0027] FIG. 1 is a schematic diagram showing a panel of a light pollution reduction smart panel system according to an embodiment of the present invention. Referring to FIG. 1, the light pollution reduction smart panel system (10) may include a plurality of panels (100) and a control device (200) that transmits a signal to the plurality of panels (100).

[0028] A plurality of panels (100) may include a first panel (101) and a second panel (102). The first panel (101) and the second panel (102) may be formed with the same or similar structure. Additionally, the plurality of panels (100) may be connected to each other through a connecting member (111). Accordingly, the plurality of panels (100) may be arranged continuously to correspond to the shape of a work area or activity area.

[0029] Each panel (100) included in a plurality of panels (100) may include a body (110), a cover (120), a plurality of motion sensors (130), and a lighting module (140). The body (110) may be formed to include an internal space. A battery (not shown), a control circuit, or electrical wiring may be placed in the internal space. Additionally, coupling members (111) may be formed on both sides of the body (110).

[0030] The connecting member (111) can be connected to an adjacent other panel (100). According to one embodiment, the connecting member (111) can be connected in an angle-adjustable manner. Thus, a plurality of panels (100) can be arranged around the work area in a curved or polygonal shape. By utilizing this, the user can direct light toward the area where work is being performed.

[0031] A light reflection reduction ridge (not shown) may be formed on the lower part of the body (110). Specifically, the light reflection reduction ridge may be formed to protrude along the lower front surface of the body (110). Thus, the light reflection reduction ridge can reduce the reflection of light generated from the lighting module (140) from the floor surface, thereby reducing glare for the worker and reducing unnecessary light reflection into the surrounding area.

[0032] For example, light generated from the lighting module (140) may be directed toward the area where work is being performed and then reflected from the floor surface. At this time, the light reflection reduction ridge can limit the path of the reflected light to reduce the reflected light spreading in the left-right or upward direction.

[0033] A cover (120) may be positioned on the upper part of the body (110). According to one embodiment, the cover (120) may have a roof shape formed to slope downward from the center of the body (110) toward the outside. Thus, rainwater or foreign matter can be discharged to the outside of the cover (120), thereby protecting the internal components from the external environment. Additionally, the cover (120) may be formed to cover the upper part of the lighting module (140) to block light leakage in the upward direction.

[0034] The cover (120) may include a main cover (not shown) containing an internal space and an auxiliary cover (not shown) that is inserted into the internal space and slides. Accordingly, the protruding length or light-blocking range of the cover (120) can be adjusted, and the range of light generated by the lighting module (140) can be controlled more effectively.

[0035] A solar cell (400) may be placed on the upper part of the cover (120). The solar cell (400) can generate electrical energy using sunlight. The generated electrical energy can be stored in a battery (not shown). Accordingly, a light pollution reduction smart panel system according to one embodiment can operate without an external power supply and can receive energy in an environmentally friendly manner.

[0036] A plurality of motion sensors (130) are positioned adjacent to the cover (120) and can detect the movement of an object. In one embodiment, a plurality of motion sensors (130) are positioned on the lower surface of the cover (120) and may be spaced apart from each other. A plurality of motion sensors (130) may include a first motion sensor (131) and a second motion sensor (132). In this case, the distance between the first motion sensor (131) and the lighting module (140) may be formed to be the same as the distance between the second motion sensor (132) and the lighting module (140). Thus, a uniform detection area can be formed centered on the lighting module (140), and the area and direction in which movement occurs can be detected more accurately.

[0037] The lighting module (140) may be positioned adjacent to the cover (120). In one embodiment, the lighting module (140) may be positioned on the lower surface of the cover (120). Accordingly, upward light may be blocked by the cover (120), and the light from the light source may be concentrated on the lower activity area.

[0038] Here, the lighting module (140) can be placed in the central part of the lower surface of the cover (120). Thus, the lighting module (140) can form a uniform illumination area around the panel (100) and has the effect of reducing leakage light that spreads into the surrounding environment. The lighting module (140) will be described in detail below with reference to FIG. 2.

[0039] The control device (200) is spaced apart from the outside of the panel (100) and can communicate wirelessly with a plurality of panels (100). For example, the control device (200) may be mounted on a vehicle or means of transport placed at a construction site or work area. Although FIG. 1 illustrates the control device (200) being mounted on a vehicle, it is not limited thereto and may be a server. Additionally, a worker terminal (not shown) may communicate with the server to transmit a control signal to the server, and the server may transmit a control signal to the panel (100) to control the light source (141) or the rotating device (143) based on the control signal.

[0040] Accordingly, the control device (200) can remotely control multiple panels (100), and the installation location of the control device (200) can be flexibly changed according to the working environment.

[0041] The control device (200) can control the lighting module (140) based on preset time data and the signal from the motion sensor (130). Specifically, the control device (200) can control the light source (141) to be turned on when the current time falls within the night time period, and can control the illumination direction of the light source (141) based on the sensing value of the motion sensor (130). In addition, the control device (200) can automatically set or change the start and end times of the night time period based on time information corresponding to the current location received from a GPS module (not shown).

[0042] Accordingly, the smart panel system (10) can more accurately control the lighting time of the light source (141) in response to sunrise and sunset times that change according to the season or region. The method of the control device (200) controlling the light source (141) and the rotating device (143) will be explained in detail below with reference to FIGS. 4 and FIGS. 5.

[0043] A smart panel system (10) according to one embodiment may further include an illuminance sensor (300). The illuminance sensor (300) can detect the ambient brightness of the panel (100). Specifically, the illuminance sensor (300) can generate a sensing value corresponding to the illuminance of the surrounding environment and transmit it to a control device (200). Accordingly, the control device (200) can adjust the brightness of the light source (141) in response to the brightness of the surrounding environment, thereby securing the illuminance required for the operation while reducing unnecessary energy consumption and light pollution.

[0044] Meanwhile, in a smart panel system (10) according to one embodiment, each of the plurality of panels (100) may further include an energy sensor (not shown). Additionally, the control device (200) can control the transmission and reception of electrical energy to and from each other through the energy terminal (not shown) of the coupling member (111) based on the sensing value of the energy sensor.

[0045] For example, an energy sensor of the first panel (101) can generate a first energy sensing value based on the remaining energy of a battery (not shown) placed in the first panel (101). The control device (200) can determine whether the first energy sensing value is below a preset energy threshold. If the first energy sensing value is below the preset energy threshold, the control device (200) can determine that there is insufficient electrical energy required for the operation of the first panel. Accordingly, the control device (200) can control the transfer of electrical energy stored in the battery (not shown) of the second panel (102) to the battery of the first panel (101) through the energy terminal of the coupling member (111).

[0046] Accordingly, even if the battery level of a specific panel (100) is low, electric energy can be supplied from an adjacent panel (100), and the operational stability of the system can be improved.

[0048] FIG. 2 is a drawing for explaining a lighting module of a light pollution reduction smart panel system according to one embodiment of the present invention.

[0049] Referring to FIG. 2, the lighting module (140) may include a light source (141) that generates light, a light shield (142) that surrounds the outer surface of the light source (141), and a rotating device (143) that rotates the light source (141) and the light shield (142).

[0050] The lighting module (140) may include a light source (141), a snoot (142), and a rotating device (143). In one embodiment, the light source (141) may generate light. Additionally, the light source (141) may be positioned at a location corresponding to the central axis of the snoot (142). Accordingly, the light generated from the light source (141) can be stably irradiated parallel to the inner surface of the snoot (142).

[0051] The light source (141) can generate light with a wavelength of 580 nm to 700 nm to reduce scattering of upward light and leakage light. Generally, light with a relatively short wavelength is scattered more by fine particles or water vapor in the air. On the other hand, light with a relatively long wavelength is scattered less by the atmosphere. Therefore, light with a wavelength of 580 nm to 700 nm generated by the light source (141) can reduce light pollution by reducing the diffusion of light due to scattering in the atmosphere compared to light with a wavelength of less than 580 nm.

[0052] Meanwhile, long wavelength light exceeding 700 nm reduces scattering in the atmosphere, but it may be difficult to secure the illumination required for work due to reduced visibility for the worker. Therefore, the light source (141) can be manufactured to generate light of a wavelength of 580 nm to 700 nm, taking into consideration the reduction of light scattering and securing visibility of the work area.

[0053] The light shield (142) may have a cylindrical shape with an open bottom and surround the outer side of the light source (141). Here, the diameter of the bottom of the light shield (142) may be formed to be larger than the diameter of the light source (141). Accordingly, light generated from the light source (141) can be irradiated through the light shield (142), thereby reducing lateral light leakage. Additionally, since the light generated from the light source (141) is not obscured by the light shield (142), sufficient illumination required for work can be secured.

[0054] The inner surface of the light-shielding tube (142) may be formed with a matte surface to reduce diffuse reflection of light. For example, the inner surface of the light-shielding tube (142) may include a black coating layer or a light-absorbing layer. Accordingly, light generated from the light source (141) can be prevented from being reflected from the inner surface of the light-shielding tube (142) and leaking out.

[0055] The light shield (142) is mechanically connected to the light source (141) and can be rotated together by the driving of the rotating device (143). Accordingly, the light shield (142) rotates together to correspond to the irradiation direction of the light source (141), thereby continuously reducing lateral light leakage diffusion.

[0056] The lighting module (140) can be rotatably positioned on the lower surface of the cover (120) via a rotating device (143). Specifically, the rotating device (143) can rotate the light source (141) and the light shield (142). Here, the rotating device (143) can be rotated by a rotation signal received from the control device (200). Through this, the light source (141) and the light shield (142) are rotated toward an activity area where movement occurs, and light can be irradiated toward the area where movement occurs.

[0057] The rotating device (143) may include a fixed part (not shown) fixed to the lower surface of the cover (120) and a rotating part (not shown) to which a light source (141) is connected. Accordingly, the light source (141) can be rotated at various angles on the lower surface of the cover (120).

[0058] In one embodiment, the rotating device (143) can rotate the light source (141) around a rotation axis so that the direction in which the light source (141) irradiates light is changed. Specifically, the rotating device (143) can rotate the light source (141) in the left-right direction relative to the panel (100). At the same time, the rotating device (143) can rotate the light source (141) in the forward-backward direction relative to the panel (100), which is a direction closer to or further away from the panel (100). For example, the rotating device (143) can rotate the light source (141) so that it faces the left or right side of the panel (100), and at the same time rotate it in the forward-backward direction so that it faces the near or far side of the panel (100). Accordingly, the light source (141) can selectively irradiate light toward an activity area where movement occurs through the rotating device (143).

[0059] The maximum rotation angle of the rotating device (143) may be limited. Specifically, the maximum rotation angle of the rotating device (143) may be set so that the irradiation direction of the light source (141) is maintained at a horizontal direction parallel to the ground or lower. For example, the angle formed by the central axis of the light source (141) and the ground may be limited to a range of 0 degrees or more and less than 90 degrees. Accordingly, the lighting module (140) of one embodiment can prevent the light of the light source (141) from being irradiated in an upward direction, thereby reducing the diffusion of upward light and leakage light.

[0060] The rotating device (143) may include a reduction gear. Accordingly, the rotating device (143) can prevent the light source (141) from rotating rapidly and can more stably control the irradiation direction of the light source (141).

[0062] FIG. 3 is a diagram illustrating an operation sensor of a light pollution reduction smart panel system according to an embodiment of the present invention.

[0063] Referring to FIG. 3, the motion sensor (130) may be positioned on the lower surface of the cover (120). Specifically, the motion sensor (130) may be positioned at locations spaced apart from each other with respect to the lighting module (140). For example, the motion sensor (130) may include a first motion sensor (131) positioned on the left side of the lighting module (140) and a second motion sensor (132) positioned on the right side.

[0064] Additionally, the first motion sensor (131) and the second motion sensor (132) may be arranged symmetrically with respect to each other with respect to the lighting module (140). Specifically, the distance between the first motion sensor (131) and the lighting module (140) may be the same as the distance between the second motion sensor (132) and the lighting module (140). Accordingly, the first motion sensor (131) and the second motion sensor (132) can form a left-right symmetrical detection range with respect to the lighting module (140). Thus, the motion sensor (130) can uniformly detect movements occurring in the left-right direction.

[0065] Meanwhile, the detection area of ​​the first motion sensor (131) and the detection area of ​​the second motion sensor (132) may be formed to partially overlap. Accordingly, the detection blind spot of the motion sensor (130) can be reduced, and the activity area where movement occurred can be determined more accurately.

[0066] In one embodiment, the smart panel system (10) may further include additional motion sensors (130). For example, the smart panel system (10) may further include a third motion sensor positioned in front of the lighting module (140) and a fourth motion sensor positioned behind the lighting module (140). This allows the smart panel system (10) to improve the performance of determining an activity area where motion is detected.

[0067] The motion sensor (130) may include a Passive Infrared Sensor (PIR sensor), an ultrasonic sensor, or a radar sensor. Accordingly, the motion sensor (130) can detect the movement of a human body or an object. And when movement is detected, the motion sensor (130) can generate a detection signal and transmit it to the control device (200).

[0068] The detection range of the motion sensor (130) may be limited to a preset detection distance. For example, the motion sensor (130) may be set to detect movement within a range of 3m to 10m relative to the panel (100). Accordingly, the operation of the lighting module (140) due to unnecessary movement in a distant area can be reduced.

[0069] Subsequently, the control device (200) can transmit a rotation signal to the rotating device (143) based on the detection signal of the motion sensor (130) to control the light source (141) so that it faces the activity area. The method of the control device (200) determining the activity area based on the detection signal of the motion sensor (130) and controlling the rotating device (143) will be explained in detail below with reference to FIG. 5.

[0071] FIG. 4 is a diagram illustrating the sequence in which a control device of a light pollution reduction smart panel system according to an embodiment of the present invention controls the lighting of a light source. Referring to FIG. 4, the step (S100) of the control device controlling the light source may include a step of determining whether the current time corresponds to nighttime (S101), a step of limiting the lighting of the light source (S102), a step of determining whether the sensing value of the illuminance sensor is less than an illuminance threshold value (S103), a step of transmitting a first lighting signal to the light source (S104), and a step of transmitting a second lighting signal to the light source (S105).

[0072] FIG. 4 illustrates steps S101 to S105 being performed sequentially, but is not limited thereto, and some steps may be changed, some steps omitted, or new steps added. For example, before proceeding with step S101, the control device (200) may receive weather information from an external server. And if the received weather information includes information corresponding to a rainy or foggy condition, the control device (200) may transmit a lighting signal to the light source (141) regardless of the time data and the sensing value of the illuminance sensor (300). Accordingly, the smart panel system (10) can ensure visibility of the work area even in adverse weather conditions and can improve work stability.

[0073] The step (S101) of determining whether the current time corresponds to nighttime is a step in which the control device (200) determines whether the current time corresponds to nighttime when the light source (141) needs to be turned on. Specifically, in step S101, the control device (200) can determine whether the current time is the first time based on pre-set time data.

[0074] Here, the first time may refer to a time included in the nighttime period when lighting is required due to a decrease in the brightness of the surrounding environment. Specifically, the first time may be set to the time period from after the usual evening time until before sunrise. More specifically, the first time may be set to the time period from 18:00 until before 06:00 the next day, but may be set in various ways depending on the season and region. To this end, the control device (200) may communicate with a GPS module (not shown) to receive time information corresponding to the current location.

[0075] For example, the GPS module can provide time information for the current location, sunrise time, or sunset time. And the control device (200) can automatically set or change the start time and end time of the first time based on time information corresponding to the location where the panel (100) is installed. Accordingly, the time at which the light source (141) is turned on can be accurately controlled in response to sunrise and sunset times that change according to the season or region.

[0076] The step (S102) of limiting the lighting of the light source (141) is a step in which the control device (200) limits the lighting by not transmitting a lighting signal to the light source (141). Specifically, in step S102, if the current time does not correspond to the first time, the control device (200) may determine that the current time is a time included in the daytime time period rather than the nighttime time.

[0077] And the control device (200) may not transmit a lighting signal to the light source (141). Accordingly, the smart panel system (10) can save energy by preventing the light source (141) from being unnecessarily lit during daytime hours. In addition, the smart panel system (10) can reduce light pollution spreading into the surrounding environment by limiting the use of unnecessary lighting.

[0078] The step (S103) of determining whether the sensing value of the illuminance sensor (300) is less than a preset illuminance threshold is a step in which the control device (200) controls the brightness of the light source by comparing the sensing value of the illuminance sensor (300) with a preset illuminance threshold. Specifically, in step S103, the illuminance sensor (300) can detect the ambient brightness of the panel (100) and can generate a sensing value corresponding to the detected brightness.

[0079] For example, when the brightness of the surrounding environment decreases, the light sensor (300) can generate a relatively small sensing value, and when the brightness of the surrounding environment increases, it can generate a relatively large sensing value. And the control device (200) can receive the sensing value generated from the light sensor (300) and compare it with a light threshold value.

[0080] Here, the illuminance threshold can be set as a reference illuminance value to distinguish between nighttime illuminance conditions and late-night illuminance conditions. For example, a preset illuminance threshold can be set to a brightness selected in the range of 1 lux to 20 lux, but is not limited thereto.

[0081] In step S103, the control device (200) can determine that the brightness of the surrounding environment is in a nighttime illumination state if the sensing value of the illuminance sensor (300) is greater than or equal to the illuminance threshold. Subsequently, through step S104, the control device (200) can transmit a first lighting signal to the light source (141) so that the light source (141) generates light of a first brightness.

[0082] On the other hand, if the sensing value of the illuminance sensor (300) is less than the illuminance threshold, it can be determined that the brightness of the surrounding environment is in a nighttime illuminance state. Subsequently, the control device (200) can transmit a second lighting signal to the light source (141) through step S105 so that the light source (141) generates light of a second brightness that is brighter than the first brightness.

[0083] The step (S104) of transmitting a first lighting signal to the light source (141) is a step in which the control device (200) transmits a first lighting signal to the light source (141) to control it in order to generate light of a first brightness. Specifically, if the control device (200) determines that the brightness of the surrounding environment is in a nighttime illumination state, it may generate a first lighting signal to light the light source (141) to a first brightness and transmit it to the light source (141). Subsequently, the light source (141) may generate light of a first brightness based on the first lighting signal received from the control device (200). Here, the first brightness may be set to a standard brightness required in a general nighttime work environment.

[0084] The step (S105) of transmitting a second lighting signal to the light source (141) is a step in which the control device (200) transmits a second lighting signal to the light source (141) to control it in order to generate light of a second brightness. Specifically, in step S105, if the control device (200) determines that the brightness of the surrounding environment is in a late-night illumination state, it may generate a second lighting signal to light the light source (141) to a second brightness and transmit it to the light source (141). Subsequently, the light source (141) may generate light of a second brightness based on the second lighting signal received from the control device (200).

[0085] Here, the second brightness can be set to a brightness greater than the first brightness. In this case, the second brightness can be set to a brightness that ensures visibility for the worker in a late-night work environment where the surrounding environment is very dark. Therefore, the user can clearly check the condition of the work area even during late-night hours and work safely. In addition, the smart panel system (10) can selectively adjust the brightness of the light source (141) according to the brightness of the surrounding environment, thereby ensuring the illumination required for work while reducing unnecessary energy consumption and light pollution.

[0087] FIG. 5 is a diagram illustrating the sequence in which a control device of a light pollution reduction smart panel system according to an embodiment of the present invention controls the operation of a rotating device. Referring to FIG. 5, the step (S200) in which the control device controls the operation of the rotating device may include a step of determining whether the current time corresponds to nighttime (S201), a step of limiting the lighting of a light source (S202), a step of determining whether movement is detected by a motion sensor (S203), a step of limiting the operation of the rotating device (S204), a step of determining an activity area based on location information (S205), and a step of transmitting a rotation signal to the rotating device (S206).

[0088] FIG. 5 illustrates steps S201 to S206 being performed sequentially, but is not limited thereto, and some steps may be changed, some steps omitted, or new steps added. For example, after step S203, if a repetitive detection signal is alternately generated from a plurality of motion sensors (130) within a preset period, the control device (200) may perform a step of limiting the operation frequency of the rotating device (143). Thus, unnecessary repetitive movements of the rotating device (143) can be reduced, thereby reducing mechanical wear and energy consumption. Here, the preset period is a reference time for determining abnormal movement and may be set as one of the times selected in the range of 0.1 seconds to 2 seconds.

[0089] The step of determining whether the current time corresponds to nighttime (S201) and the step of limiting the lighting of the light source (S202) may each be the same as the steps S101 and S102 shown in FIG. 4. Accordingly, the control device (200) can determine whether the current time corresponds to nighttime through steps S201 and S202, and based on this, determine whether to light the light source (141) and whether to operate the rotating device (143), and perform control for this purpose.

[0090] The step (S203) of determining whether motion is detected in one motion sensor is a step in which the control device (200) determines whether motion is detected in only one of the motion sensors (130) among the motion sensors (130) in which motion is detected, and determines whether to determine the activity area. Specifically, in step S203, the control device (200) can determine whether a detection signal according to motion detection is generated in only one of the motion sensors (130), either the first motion sensor (131) or the second motion sensor (132). Subsequently, the control device (200) can perform a subsequent step to determine the activity area based on the determination result.

[0091] For example, the control device (200) may determine that movement has occurred in the left area of ​​the lighting module (140) if a detection signal is generated only at the first motion sensor (131). Additionally, if a detection signal is generated only at the second motion sensor (132), it may determine that movement has occurred in the right area of ​​the lighting module (140). Subsequently, the control device (200) may perform a step to determine the activity area based on the location information of the motion sensor (130) that generated the detection signal.

[0092] On the other hand, in step S203, if a detection signal is generated from both the first motion sensor (131) and the second motion sensor (132), the control device (200) may proceed to step S204 so that the direction in which light is irradiated is not biased in a specific direction.

[0093] The step (S204) of limiting the operation of the rotating device (143) is a step in which the control device (200) limits the rotation of the rotating device (143) by not transmitting a rotation signal to the rotating device (143) without determining an activity area when detection signals are simultaneously generated from a plurality of motion sensors (130). Specifically, in step S204, the control device (200) can determine that movement has occurred in both the left area and the right area of ​​the lighting module (140) when a sensing value is generated from both the first motion sensor (131) and the second motion sensor (132).

[0094] And the control device (200) can limit the operation of the rotating device (143) so that the direction of illumination of light generated from the light source (141) is not deflected in a specific direction. Thus, the smart panel system (10) can maintain a uniform lighting environment throughout the entire activity area. In addition, unnecessary operation of the rotating device (143) can be reduced by preventing the light source (141) from being repeatedly rotated in a specific direction as a result of proceeding with step S204.

[0095] The step of determining an activity area based on location information (S205) is a step in which the control device (200) determines an activity area based on location information of a motion sensor (130) in which movement is detected. Specifically, the control device (200) can determine an activity area in which movement is detected based on location information corresponding to the location where one motion sensor (130) that generated the detection signal is placed.

[0096] For example, when a detection signal is generated from the first motion sensor (131), the control device (200) can determine an activity area based on first location information corresponding to the location of the first motion sensor (131). Alternatively, when a detection signal is generated from the second motion sensor (132), the control device (200) can determine an activity area based on second location information corresponding to the location of the second motion sensor (132).

[0097] In step S205, the activity area may be an area within a preset radius from a location or point where a motion sensor is placed. Here, the preset radius may be one radius selected from a range of 3m to 10m. Through this, the smart panel system (10) can intensively irradiate light onto the activity area to increase the efficiency of work and energy usage and reduce light leakage.

[0098] The step of transmitting a rotation signal to a rotating device (S206) is a step of transmitting a rotation signal to a rotating device (143) so that the light source (141) is directed toward the activity area. Specifically, in step S206, the control device (200) can transmit a rotation signal to the rotating device (143) so that the light source (141) is directed toward the center of the activity area determined in step S205. Subsequently, the rotating device (143) can rotate the light source (141) and the light shield (142) based on the rotation signal received from the control device (200). Accordingly, the light source (141) irradiates light toward the center of the activity area where movement occurs, thereby ensuring even illumination across the entire area.

[0100] FIG. 6 is a schematic diagram illustrating a light pollution reduction smart panel system according to another embodiment of the present invention. Referring to FIG. 6, the smart panel system (20) according to another embodiment may further include a floating member (500) for floating on water in the configuration of the smart panel system (10) according to one embodiment.

[0101] Specifically, a smart panel system (20) according to another embodiment may include a plurality of panels (100) and a floating member (500) connected to the lower part of the plurality of panels (100). The floating member (500) may be connected to the lower part of the body (110) of each of the plurality of panels (100) to float on the water surface. Accordingly, the smart panel system (20) can be installed not only on the ground but also in a water environment such as a water work area, a port, or a fish farm.

[0102] The floating member (500) may include a plate (510), a tube (520), and an elastic band (530). The plate (510) may be formed into a plate-like structure in which the panel (100) is received or supported. The plate (510) may be placed at the bottom of each of the plurality of panels (100) to support the panel (100) so that it is stably maintained above the water surface.

[0103] The tube (520) can be connected to the lower part of the plate (510). The tube (520) can be inflated by injecting air and can provide buoyancy in the inflated state. Additionally, the tube (520) can be deflated when the air is removed. Accordingly, the floating member (500) can float on the water surface when in use and can reduce its volume when stored or transported, making it easy to transport and store.

[0104] The elastic band (530) can be joined to the outer surfaces of the plate (510) and the tube (520) by being in close contact with them. Specifically, the elastic band (530) can be connected to the plate (510) while wrapping around the outer surface of the tube (520). Accordingly, the tube (520) can be prevented from detaching from the bottom of the plate (510), and the stability of the panel (100) can be improved even in an environment where water surface swaying occurs.

[0105] The elastic band (530) may be manufactured from an elastic material. For example, the elastic band (530) may include rubber, silicone, polyurethane, or elastomer. Accordingly, the elastic band (530) may deform in response to the expansion or contraction of the tube (520) and may securely bond the plate (510) and the tube (520). Additionally, since the elastic band (530) may partially absorb vibrations caused by external impact or shaking of the water surface, it may improve the bonding stability of the floating member (500).

[0106] The elastic band (530) may include an elastic cushioning layer (531) disposed on the outer surface. The elastic cushioning layer (531) may include one or more materials selected from silicone foam, natural rubber, bio-based elastomer, and recyclable thermoplastic elastomer (TPE). Thus, the elastic cushioning layer (531) can reduce the impact applied to aquatic organisms upon collision and can mitigate vibrations caused by shaking of the water surface or external impact. Additionally, the elastic cushioning layer (531) can improve the durability of the floating member (500) by reducing damage to the outer surface of the plate (510), tube (520), and elastic band (530).

[0108] Accordingly, the smart panel system (10, 20) of the present invention can light up the light source (141) only at night based on preset time data, and control the light source (141) to light up at a different brightness depending on the night environment or late-night environment based on the sensing value of the illuminance sensor (300). In addition, when the light source (141) is lit, the direction in which light is irradiated can be controlled by rotating the light source (141) toward an activity area based on the detection signal of the motion sensor (130). Therefore, the smart panel system (10, 20) of the present invention can have the effect of reducing damage to residential areas and ecosystems caused by light pollution and enabling efficient energy use.

[0110] Although the underwater ecosystem protection type light pollution reduction smart panel system (10, 20) according to the embodiments of the present invention has been described as specific embodiments, this is merely an example and the present invention is not limited thereto and should be interpreted as having the broadest scope in accordance with the basic concept disclosed in this specification.
