Description

Technical Field

[0001] This utility model belongs to the field of lighting and intelligent monitoring technology, specifically an LED outdoor stadium light whose status can be remotely monitored. Background Technology

[0002] Over time, LED outdoor stadium lights may experience performance degradation or even malfunction due to environmental factors or equipment aging. Because of their high installation locations and large numbers, manual inspection and maintenance require significant time and manpower, thus necessitating a solution that allows for remote monitoring of the lights' status.

[0003] Currently, conventional LED stadium lights typically only possess basic lighting functions, with some products implementing simple fault alarm functions through built-in sensors. However, most of these devices rely on local indicator lights or manual detection methods to report problems, failing to achieve true remote real-time monitoring. For example, some existing lighting fixtures collect operational data through external monitoring modules, but these modules have limited data transmission range and are susceptible to external environmental interference, resulting in untimely and inaccurate information transmission.

[0004] Furthermore, existing technologies suffer from limited monitoring capabilities, providing only basic information such as switch status or current anomalies, while failing to comprehensively reflect critical parameters like temperature, light decay, and power supply stability. This makes it difficult for managers to anticipate potential problems and implement preventative maintenance, impacting the overall lifespan and lighting performance of stadium lights. Therefore, an improved remote monitoring solution is urgently needed. Utility Model Content

[0005] This utility model relates to the field of LED lighting technology, and in particular to an LED outdoor sports field light with remotely monitored status. Addressing the problem of performance degradation or even malfunction of existing LED sports field lights due to environmental factors or equipment aging, especially in cases of high installation locations and large numbers, where manual inspection and maintenance consume significant time and manpower, and where existing lighting status monitoring suffers from limited dimensions and untimely and inaccurate information transmission, this utility model provides an LED outdoor sports field light with remotely monitored status, enabling comprehensive monitoring and real-time remote feedback of the light's operating status.

[0006] The LED outdoor stadium light includes a lamp body assembly, a sensing module, a communication module, and a central control unit.

The central control unit also has an independent power interface connected to a backup battery to ensure that basic functions can be maintained even when the main power supply fails.

[0010] The lamp assembly has a protective cover on its outer side, which is bolted to the outer surface of the housing.

Detailed Implementation

[0021] This utility model provides an LED outdoor sports field light with remotely monitored status. The specific embodiments of this utility model are described in detail below with reference to the accompanying drawings. Figure 1 As shown, the LED outdoor stadium light includes a lamp body assembly 1, a sensing module 5, a communication module 9, and a central control unit 12. The components are mechanically fixed and electrically connected to achieve coordinated operation of the overall function.

[0022] The lamp assembly 1 consists of a housing 2, a light source module 3, heat sinks 4, and a protective cover 16. The housing 2 is the main load-bearing structure of the lamp, and its interior forms a space to house the light source module 3 and other electronic components. The light source module 3 is fixed to the inner bottom surface of the housing 2 and is connected to an external power source via wires to provide power. The substrate of the light source module 3 is directly attached to the inner wall of the housing 2 to ensure maximum heat conduction efficiency. Multiple heat sinks 4 are evenly distributed along the height of the exterior of the housing 2, with ventilation gaps between each heat sink 4 to allow airflow and enhance heat dissipation. Figure 2 As shown, the protective cover 16 is fixed to the outer surface of the housing 2 by bolts. The protective cover 16 is made of transparent material and coated with an anti-reflective coating 17 on its inner surface to reduce the impact of light reflection on the light attenuation detector 7. The exterior of the protective cover 16 is provided with a drainage channel 18, which is arranged around the circumference of the protective cover 16 to guide rainwater to the outside of the housing 2 and prevent water accumulation from damaging the lamp.

[0023] Sensing module 5 includes a temperature sensor 6, a light decay detector 7, and a current detector 8. For example... Figure 3 As shown, temperature sensor 6 is embedded in the substrate of light source module 3 and in direct contact with the substrate. It is connected to central control unit 12 via a signal transmission line. Light decay detector 7 is installed near the light-emitting surface of light source module 3, with its detection end facing the light-emitting center of light source module 3, for real-time monitoring of changes in light output intensity of light source module 3. Current detector 8 is connected in series in the power supply circuit of light source module 3 to detect current fluctuations in the power supply circuit and transmits the collected data to central control unit 12 for processing via a signal transmission line.

[0024] Communication module 9 includes wireless transmission unit 10 and antenna 11, such as Figure 4As shown, the wireless transmission unit 10 is fixed to the inner side wall of the housing 2 and connected to the central control unit 12 via a data interface. The antenna 11 penetrates the side wall of the housing 2 and extends to the outside to ensure stable signal transmission. The wireless transmission unit 10 supports multiple communication protocols, including but not limited to Wi-Fi, LoRa, and NB-IoT, and can select the appropriate transmission method according to actual needs. For example, in scenarios requiring long-distance, low-power transmission, the LoRa protocol can be selected; while in scenarios requiring high-bandwidth transmission, the Wi-Fi protocol can be selected.

[0025] The central control unit 12 includes a microprocessor 13, a memory 14, and an alarm module 15, such as... Figure 5 As shown, the microprocessor 13 is fixed to the internal base plate of the housing 2 and connected to the memory 14 via a circuit board. The memory 14 is used to store historical data collected by the sensing module 5, and the microprocessor 13 is responsible for analyzing and judging the received data. When a parameter exceeds a preset threshold, the microprocessor 13 will trigger the alarm module 15, which will send an alarm signal to the remote monitoring terminal via the communication module 9. The central control unit 12 is also equipped with an independent power interface connected to a backup battery to ensure that basic functions can be maintained even when the main power supply fails.

[0026] The operating principle of this utility model is as follows: During operation, the light source module 3 generates heat, which is conducted through the substrate to the housing 2 and the heat sink 4. The ventilation gap between the heat sinks 4 allows air circulation to reduce the operating temperature of the lamp. The temperature sensor 6 collects the operating temperature data of the light source module 3 in real time and transmits the data to the central control unit 12. The microprocessor 13 determines whether the temperature is abnormal based on a preset threshold. At the same time, the light decay detector 7 monitors the change in light output intensity of the light source module 3. When the light output intensity is lower than the set value, the microprocessor 13 records the information and generates a corresponding report. The current detector 8 detects the current fluctuation in the power supply circuit. If the current fluctuation exceeds the normal range, the microprocessor 13 will immediately trigger the alarm module 15 and send an alarm signal to the remote monitoring terminal through the communication module 9. The wireless transmission unit 10 realizes remote data transmission through the antenna 11. Managers can view the operating status of the lamp and obtain historical data through the remote monitoring terminal.

[0027] In practical applications, such as a large outdoor basketball court equipped with multiple LED outdoor court lights of this invention, managers can monitor the operating status of each light in real time via a remote monitoring terminal. When a light experiences excessive temperature or light decay, the system automatically sends an alarm signal, allowing managers to quickly locate the faulty light and arrange for maintenance personnel to repair it. Furthermore, because the wireless transmission unit 10 supports multiple communication protocols, suitable transmission methods can be flexibly selected in different scenarios to improve data transmission reliability and coverage.

[0028] The design of the protective cover 16 further enhances the protective capabilities of the luminaire. For example... Figure 6 As shown, the anti-reflective coating 17 of the protective cover 16 reduces the impact of light reflection on the light attenuation detector 7, making the monitoring of light output intensity more accurate. The design of the drainage channel 18 effectively avoids damage to the lamp caused by rainwater accumulation, thereby extending the lamp's service life.

[0029] This utility model, through the combination of the above-mentioned technical means, solves the problems of single dimension of lamp status monitoring and untimely and inaccurate information transmission in the prior art. It realizes comprehensive monitoring and remote real-time feedback of the operating status of LED outdoor stadium lights, providing managers with reliable decision-making basis and significantly improving the maintenance efficiency and service life of lamps.

[0030] To enable those skilled in the art to fully understand and implement this utility model, the specific implementation principle of this utility model is further explained below in conjunction with a specific application scenario.

[0031] In practical applications, for example, a large outdoor basketball court may be equipped with multiple LED outdoor court lights of this invention. Managers can monitor the real-time operating status of each light fixture via a remote monitoring terminal and quickly locate faulty lights based on system feedback. The following are the specific steps and technical principles of the collaborative operation of each functional module during the light fixture's operation:

[0032] First, when the lamp is powered on, the light source module 3 begins to work and generates heat. The substrate of the light source module 3 is directly attached to the inner wall of the housing 2, and heat is rapidly transferred to the housing 2 and the heat sink 4 through thermal conduction. The ventilation gaps between the heat sinks 4 allow airflow, thereby dissipating heat into the external environment and reducing the operating temperature of the lamp. The temperature sensor 6 is embedded in the substrate of the light source module 3, with its detection end in direct contact with the substrate, enabling it to collect the operating temperature data of the light source module 3 in real time. This data is transmitted to the microprocessor 13 in the central control unit 12 for analysis via a signal transmission line. The microprocessor 13 determines whether the lamp is in an abnormally high temperature state based on a preset temperature threshold. If the temperature exceeds the set value, the microprocessor 13 will trigger the alarm module 15, which will send an alarm signal to the remote monitoring terminal via the communication module 9, reminding the management personnel to take appropriate measures.

[0033] Secondly, the light decay detector 7 is installed near the emitting surface of the light source module 3, with its detection end facing the emitting center of the light source module 3, to monitor the changes in the light output intensity of the light source module 3 in real time. The light decay detector 7 transmits the collected light output intensity data to the central control unit 12 via a signal transmission line. The microprocessor 13 analyzes the received data and compares it with the historical data recorded in the memory 14. If the light output intensity is lower than the preset value, the microprocessor 13 generates a corresponding report and uploads the information to the remote monitoring terminal via the communication module 9. Managers can view the light decay status of the lamps through the terminal and determine whether it is necessary to replace the light source module 3 or perform other maintenance operations.

[0034] Meanwhile, a current detector 8 is connected in series in the power supply circuit of the light source module 3 to detect current fluctuations in the power supply circuit. The current detector 8 transmits the collected current data to the central control unit 12 via a signal transmission line. The microprocessor 13 analyzes the received current data, and if it finds that the current fluctuation exceeds the normal range, it immediately triggers the alarm module 15, which sends an alarm signal to the remote monitoring terminal via the communication module 9. This function can promptly detect abnormalities in the power supply circuit and prevent damage to the lamps due to power supply problems.

[0035] The wireless transmission unit 10 transmits data remotely via antenna 11. The wireless transmission unit 10 supports multiple communication protocols, including but not limited to Wi-Fi, LoRa, and NB-IoT, allowing selection of the appropriate transmission method based on actual needs. For example, LoRa can be selected for scenarios requiring long-distance, low-power transmission, while Wi-Fi can be chosen for scenarios requiring high-bandwidth transmission. Administrators receive operating status data from the lighting fixtures via a remote monitoring terminal and can view historical records at any time to gain a comprehensive understanding of the fixtures' usage.

[0036] Furthermore, the design of the protective cover 16 further enhances the luminaire's protective capabilities. The anti-reflective coating 17 of the protective cover 16 reduces the impact of light reflection on the light attenuation detector 7, making the monitoring of light output intensity more accurate. The drainage channel 18 is arranged circumferentially along the protective cover 16, which can guide rainwater to the outside of the housing 2, preventing water accumulation from damaging the luminaire. This design not only improves the luminaire's waterproof performance but also extends its service life.

[0037] In summary, this invention achieves comprehensive monitoring and real-time remote feedback of the operating status of LED outdoor stadium lights through multi-dimensional data acquisition by the sensing module 5, remote data transmission by the communication module 9, and intelligent analysis and processing by the central control unit 12. Managers can quickly locate faulty lights based on the data provided by the system and arrange for maintenance personnel to carry out repairs. This technical solution significantly improves the maintenance efficiency and lifespan of the lights, providing managers with a reliable basis for decision-making.
