Description

Technology Field

[0001] The present invention relates to an outdoor lighting device that is easy to maintain, and more specifically, to an outdoor lighting device that is easy to maintain in which a connection box and input / output connection terminals are integrated and installed inside a lamp post, thereby facilitating maintenance, minimizing electrical accidents, and enabling the detection of dangerous situations. Background Technology

[0002] Generally, outdoor lighting fixtures are lighting facilities, including streetlights and security lights, installed along roads and sidewalks, residential areas, and nearby facilities; they are turned on when visibility is reduced due to nighttime, rain, fog, etc., or for security purposes.

[0003] Recently, with the expansion of daily living time and the increase in leisure spaces, the demand for lighting fixtures is also increasing in parks, cultural facilities, and neighborhood facilities.

[0004] Outdoor lighting fixtures consist of a light-emitting fixture, a lamppost that supports the fixture, and a power supply unit that supplies power to the fixture. The power supply unit includes components for supplying and cutting off power to the fixture, such as power cables, terminals, and switches; these components are embedded in a device called a junction box and installed at any location on the lamppost.

[0005] The structure of the junction box involves installing earth leakage circuit breakers or circuit breakers and wiring inside the box. Due to the large internal space, condensation caused by the temperature difference between the lamp post and the junction box frequently leads to moisture accumulating within the earth leakage circuit breakers or breakers, resulting in corrosion and subsequent failure of the wiring equipment. Additionally, there is a disadvantage in that the junction box must be opened to operate the circuit breaker for testing streetlights.

[0006] In addition, since the junction box is not waterproof, if it is submerged, water fills the interior, causing electricity to flow through the electrical connections. This leakage can lead to electric shock if people pass through the water.

[0007] In addition, the junction box had the disadvantage of being inconvenient and significantly reducing workability when the ballast, which is the most frequently failing component in the lighting fixture wiring system, failed because the junction box was large, requiring it to be pulled out of the opening to perform work.

[0008] Furthermore, since junction boxes consist of opaque containers, workers must dismantle them to check the status of power circuit breakers or cable connections. In particular, if a light fixture is not functioning properly, the junction box must be inspected to determine the cause of the malfunction. However, while the malfunction could be due to a problem with the fixture itself or a power outage, unnecessarily dismantling the junction box may occur even in these cases.

[0009] Therefore, there is a need for technology that allows for convenient maintenance of outdoor lighting devices while enabling the external checking of abnormal conditions in lighting fixtures without dismantling the junction box. Prior art literature

[0044] FIG. 1 is a perspective view of an easy-to-maintain outdoor lighting device according to a preferred embodiment of the present invention, which may include a lamp post (10), a lighting fixture (100), and a connection box (200).

[0045] The lamp post (10) is embedded or mounted on one end of the floor, has a light fixture (100) installed on the top, has a connection box (200) built inside, and serves to support the light fixture (100).

[0046] The lighting fixture (100) provides lighting and collects surrounding environment information and transmits it to the connection box (200).

[0047] As illustrated in FIG. 3, such a lighting fixture (100) may include an environmental information collection unit (110) that collects environmental information and traffic information around an outdoor lighting device as environmental information, a lighting control unit (150) that controls the control of the lighting (130) and the transmission of the collected environmental information, a power supply unit (140) that lights up the lighting (130) with power supplied from a connection box (200) or supplies driving power to parts that require power, and a communication unit (160) for communication with the connection box (200).

[0048] Additionally, the lighting fixture (100) includes a self-diagnosis unit (120) that obtains lighting status information through self-diagnosis and transmits it to the lighting control unit (150), and the lighting control unit (150) can control the transmission of the lighting status information obtained through the self-diagnosis unit (120) to the connection box (200) via communication.

[0049] The connection box (200) is built into any location of the light post (10) and includes a light fixture input / output connection terminal for connecting the light fixture (100), and performs the function of diagnosing the status of the light fixture (100), detecting dangerous situations around the outdoor lighting device, and transmitting data.

[0050] Preferably, the connection box (200) may include, as shown in FIG. 2, a main body (210) that accommodates a controller (250) and a power terminal (270) in an internal space, a cable inlet pipe (230) formed on the outside of the main body (210) for introducing a power cable (300) to supply power to a lighting fixture (100), and a transparent door (211) formed on the front of the main body (210) so that the inside of the main body can be visually inspected. In FIG. 2, reference numeral 220 represents a fastening part, and 260 represents a connection cable.

[0051] Additionally, as illustrated in FIG. 4, the controller (250) comprises a communication unit (251) that transmits and receives data through communication with the lighting fixture (100), a power supply unit (252) that supplies driving power to the lighting fixture (100), an information collection unit (253) that collects environmental information from the lighting fixture (100) through the communication unit (251), a lighting condition diagnosis unit (254) that extracts lighting diagnosis information from the environmental information collected through the information collection unit (253), a risk situation analysis unit (255) that extracts risk situation information from the environmental information collected through the information collection unit (253) and analyzes the extracted risk situation information, and a main unit that controls the power supply of the lighting fixture (100) through the control of the power supply unit (252), and controls the transmission of environmental information by generating lighting diagnosis data obtained from the lighting condition diagnosis unit (254) and risk situation analysis information obtained from the risk situation analysis unit (255) into a remote outdoor lighting device management system. It may include a control unit (257), a storage unit (256) that stores the environmental information, and a data transmission unit (258) that transmits lighting diagnostic information and risk situation analysis information to the outdoor lighting device management system via communication according to the control of the main control unit (257).

[0052] The above data transmission unit (258) can transmit data to an outdoor lighting device management system via wired communication or wireless communication.

[0053] Preferably, the risk situation analysis unit (255) determines whether a risk situation exists by analyzing environmental information collected in real time through the lighting fixture (100) and traffic information collected in real time using a camera embedded in the lighting fixture (100), and determines whether a risk object appears by analyzing traffic information using a preset judgment criterion. If a risk object appears, it transmits the information to an outdoor lighting device management system to warn the vehicle ahead about the protrusion of the risk object. If no risk object appears, it obtains traffic information such as the number of vehicles, average speed, standard deviation of speed, occupancy rate (time, space), and headway based on a set time. It calculates the number of vehicles, average speed, standard deviation of speed, average occupancy rate (time, space), and average headway existing within the same link (by section) and lane within a set time to extract the speed and average headway. Based on the extracted information, if the vehicle speed is lower than a preset standard speed and the average headway is greater than a preset standard headway, it analyzes it as a non-risk situation. If the calculated speed is higher than a preset standard speed and the average headway is greater than a preset standard If it is smaller than the head-to-head gap, it can be analyzed as a dangerous situation.

[0054] The operation of the easy-to-maintain outdoor lighting device according to a preferred embodiment of the present invention configured as described above is specifically explained as follows.

[0055] First, a lamp post (10) is fixedly installed by embedding or mounting it on one end of the floor, a light fixture (100) is installed on the upper part of the lamp post (100), and a connection box (200) is built inside, and the light fixture (100) and the connection box (200) are connected by a data and power cable using a connector connection method so that data communication and power supply are provided.

[0056] Here, by connecting the data cable and power cable of the light fixture (100) and the junction box (200) using a connector connection method, when replacing the light fixture, only the light fixture cable is disconnected from the connector, and after replacing the light fixture, the cables of the light fixture and the junction box are reconnected through the connector, thereby providing convenience for maintenance such as replacing the light fixture.

[0057] Meanwhile, the power cable (300) introduced into the cable inlet conduit (230) is connected to a plurality of power terminals (270) that function as power supply lines. The plurality of power terminals (270) and the controller (250) are electrically connected through a connection cable (260). Here, the controller (250) also performs the role of a power breaker.

[0058] The above cable inlet pipe (230) may be formed in a stepped shape in which the cross-sectional area decreases as it goes downward, or in a tapered shape in which the cross-sectional area decreases as it goes downward.

[0059] A street light connection cable (400) extending from the controller (250) through a connector is drawn out toward a light fixture located at the top through a through hole located on the lower surface of the main body (210). The connection cable (400) drawn out in this way is connected to the light fixture (100) so that power can be supplied to the light fixture (100).

[0060] The above main body (210) may be made of a plastic resin, and the plastic resin may be made of either polycarbonate resin or styrene resin. By implementing the main body (210) with a plastic resin, electrical stability can also be secured.

[0061] The above lighting fixture (100) is fixedly installed at the top of the lamp post (10) and functions as a light source and environmental monitoring equipment.

[0062] In addition, the connection box (200) accommodates a controller (power breaker) and a plurality of power terminals inside, and has a detachable transparent door (211) installed on the front.

[0063] In this invention, a connection box (200) is installed inside the lamp post (10) to simplify the connection of wires within the lamp post (10), thereby preventing leakage current at the wire connection point. Additionally, by installing a transparent door (211) on the front of the connection box (200), the power cutoff status and cable connection status inside the main body (210) can be checked at a glance. Accordingly, the connection box (200) can be avoided unnecessarily.

[0064] In addition, the structure of the cable inlet conduit (230) can be improved so that the incoming power cable (300) is not exposed to water or moisture. Accordingly, risks such as electric shock caused by the power cable (300) being exposed to water can be prevented, thereby saving maintenance costs and providing economic benefits, as well as reducing property damage in preparation for safety accidents.

[0065] Meanwhile, the installed lighting fixture (100) provides lighting and collects surrounding environment information and transmits it to the connection box (200).

[0066] This lighting fixture (100) drives the lighting (130) with power supplied from the connection box (200) in the lighting control unit (150). The lighting can be operated in the same way as a general outdoor lighting device.

[0067] In addition, the environmental information collection unit (110) of the lighting fixture (100) collects environmental information and traffic information around the outdoor lighting device as environmental information and transmits it to the lighting control unit (150).

[0068] That is, environmental information around the outdoor lighting device is collected in real time using various environmental sensors such as temperature sensors, humidity sensors, and wind direction sensors, and traffic information on the road is collected in real time using a surveillance shooting device such as a camera, and the collected environmental information and traffic information are combined to generate environmental information and transmitted to the lighting control unit (150).

[0069] The lighting control unit (150) transmits the collected environmental information to the connection box (200) through the communication unit (160).

[0070] In addition, the self-diagnosis unit (120) of the lighting fixture (100) obtains status information of the lighting (130) through self-diagnosis and transmits it to the lighting control unit (150). Here, the self-diagnosis of the lighting can diagnose the state of the lighting by diagnosing the power supply status, operation status, etc.

[0071] By self-diagnosing the lighting (130) of the lighting fixture (100) through this self-diagnosis, the inconvenience of suddenly failing to provide lighting due to a lighting failure at night, or having to detach the lighting from the lamp post to inspect the lighting, can be easily resolved.

[0072] Meanwhile, the connection box (200) supplies or cuts off driving power to the lighting fixture (100) through the power supply unit (252), and collects environmental information collected by connecting to the lighting fixture (100) via a network through the communication unit (251).

[0073] Next, the information collection unit (253) collects environmental information transmitted from the lighting fixture (100) through the communication unit (251) and transmits it to the lighting condition diagnosis unit (254) and the risk situation analysis unit (255).

[0074] The lighting status diagnosis unit (254) extracts only lighting diagnosis information from the environmental information collected through the information collection unit (253) and determines whether there is a lighting abnormality by checking the extracted lighting diagnosis information. In addition, it transmits the determined lighting status information to the main control unit (257).

[0075] In addition, the risk situation analysis unit (255) extracts risk situation information from the environmental information collected through the information collection unit (253), and analyzes the extracted risk situation information to determine whether there is a risk situation.

[0076] For example, the above-mentioned danger situation analysis unit (255) determines whether there is a danger situation by analyzing environmental information collected in real time through the lighting fixture (100) and traffic information collected in real time using a camera embedded in the lighting fixture (100), and determines whether a danger object appears by analyzing traffic information using a pre-set danger situation judgment criterion. For example, a danger situation can be determined when the vehicle speed exceeds a set speed, when vehicles drive in close proximity to each other, or when an object suddenly appears. As a result of determining the danger situation, if a danger object appears, danger situation information is generated and transmitted to the main control unit (257) to warn the vehicle ahead about the protrusion of the danger object. The main control unit (257) transmits this danger situation information in real time to the outdoor lighting device management system through the data transmission unit (258), so that the outdoor lighting device management system warns the vehicle about the appearance of the danger object and drives carefully. Here, the outdoor lighting management system can provide warning information directly to vehicles via V2X communication or warn of dangerous situations in real time using devices such as separate electronic display boards.

[0077] Meanwhile, if the analysis of the dangerous situation information reveals that it is a non-dangerous situation where no dangerous object appears, the dangerous situation analysis unit (255) obtains the number of vehicles, average speed, standard deviation of speed, occupancy rate (time, space), and headway as traffic information based on a set time, and calculates the number of vehicles, average speed, standard deviation of speed, average occupancy rate (time, space), and average headway existing within the same link (section) and lane at a set time interval to extract the speed and average headway. Subsequently, based on the extracted information, if the vehicle speed is lower than a preset standard speed and the average headway is greater than a preset standard headway, it is analyzed as a non-dangerous situation, and if the calculated speed is higher than a preset standard speed and the average headway is smaller than a preset standard headway, it can be analyzed as a dangerous situation. Here, the headway refers to the distance between the rear part of the vehicle ahead and the front part of the vehicle behind.

[0078] When a dangerous situation is analyzed, the main control unit (257) transmits this dangerous situation information in real time to the outdoor lighting device management system through the data transmission unit (258), so that the outdoor lighting device management system warns the vehicle of the dangerous situation information to promote safe driving. Here, the outdoor lighting management system can provide warning information directly to the vehicle via V2X communication or use a separate device such as an electronic display board to warn of the dangerous situation in real time.

[0079] According to the present invention described above, by installing a connection box inside the lamp post, the connection of wires within the lamp post can be simplified, thereby preventing electrical leakage at the wire connection points. Additionally, by installing a transparent door on the front of the connection box, the power cutoff status and cable connection status inside the main body can be checked at a glance. Accordingly, the connection box can be eliminated from unnecessary disassembly.

[0080] In addition, by improving the structure of the cable entry conduit, the incoming power cables can be protected from exposure to water or moisture. Consequently, risks such as electric shock caused by the cables' exposure to water can be prevented, resulting in reduced maintenance costs, economic benefits, and the ability to minimize property damage in the event of safety accidents.

[0081] In addition, the status of outdoor lighting fixtures can be diagnosed remotely in real time, allowing for optimal operation of the outdoor lighting system at all times through maintenance, such as prompt replacement of fixtures in the event of an abnormality.

[0082] In addition, by utilizing lighting fixtures as monitoring equipment to collect environmental information in real time, if a dangerous situation such as a traffic accident is predicted to occur based on this data, the danger can be warned to vehicles in the dangerous situation via V2X communication or electronic display boards, thereby preventing vehicle accidents in advance.

[0083] Although the invention made by the inventors has been specifically described according to the above embodiments, it is obvious to those skilled in the art that the invention is not limited to the above embodiments and can be modified in various ways without departing from the gist thereof.
