[0029] The following is a further detailed description of a novel LED lighting system proposed by the present invention in conjunction with the accompanying drawings and specific embodiments. The advantages and features of the present invention will become more apparent from the following description and claims.

[0030] Example

[0031] See also Figure 1 , this embodiment provides a new type of LED lighting system, which mainly includes: a current driving module, an LED light source, a main control module, an RTC clock module and a wireless communication module.

[0032] Among them, the current driving module is electrically connected to the main control module and the LED light source respectively. After the AC power of the power grid is input into the current driving module, the current driving module converts the AC power into DC power, and then powers the main control module, LED light source, RTC clock module and wireless communication module.

[0033] Specifically, the current driving module includes an AC metering module, an AC / DC module, a DC / DC constant current output module and a DC metering module which are electrically connected in sequence. After the mains power is input, it passes through the AC metering module and is input into the AC / DC module. The AC / DC module converts the AC alternating current into DC direct current, which is used to power other modules such as the AC metering module, the main control module, and the DC / DC constant current output module. The DC / DC constant current output module receives the DC direct current and outputs constant current to the LED light source.

[0034] Furthermore, the main control module and the AC metering module exchange data through a serial port or SPI connection, and the main control module and the DC metering module exchange data through a serial port or SPI connection. The AC metering module measures the voltage and current of the passing mains electricity, and calculates the frequency, active power, reactive power, active electric energy, and reactive electric energy. The main control module receives the data measured and calculated by the AC metering module through the data interaction interface, and compares it with the preset threshold to monitor the fluctuation of the power grid. The DC metering module is used to measure the voltage and current of the LED light source. The main control module receives the measurement data of the DC metering module through the data interaction interface, and compares it with the preset threshold to monitor whether the LED light source is faulty.

[0035] See also Figure 1In this embodiment, the wireless communication module connects the main control module with the external cloud platform. Therefore, the cloud platform sends the longitude and latitude information to the main control module through the wireless communication module. The main control module derives the sunrise and sunset times based on the longitude and latitude information, and compares them with the real-time time provided by the RTC clock module. When the match is successful, the main control module controls the DC / DC constant current module to turn on or off the LED light source. Specifically, the main control module and the wireless communication module are connected through SPI, serial port or RS485 for data exchange, and the main control module and the RTC clock module are connected through IIC bus for data exchange.

[0036] Preferably, the present embodiment is further provided with a storage module, and the storage module and the main control module are connected via an IIC bus for data exchange. The storage module stores a preset threshold for comparison, which is set by the cloud platform and sent to the main control module via the wireless communication module, and then the main control module stores the preset threshold in the storage module.

[0037] Now, in combination with the whole embodiment, the functions of the AC metering module and the DC metering module are described in detail: when the power grid fluctuates or the system fails, the AC metering module detects that the power grid voltage is abnormal, and the main control module can report the alarm information such as power grid fluctuations to the cloud platform in real time. At the same time, the corresponding time is recorded by the RTC clock module. If the equipment failure time is consistent with the power grid voltage fluctuation time, it can be deduced that the cause of the equipment failure is related to the power grid voltage fluctuation. Similarly, when the DC metering module detects abnormal voltage and current, the main control module reports the alarm information to the cloud platform. Similar to the AC metering module, the corresponding time can be recorded by the RTC clock module. If the equipment failure time is consistent with the voltage and current fluctuation time of the LED light source, it can be deduced that the cause of the equipment failure is related to the voltage and current fluctuation of the LED light source.

[0038] In addition, the RTC clock module can also record the time when the wireless communication module loses connection with the cloud platform, which can be used to determine the cause of the loss of connection. Specifically, if the AC metering module and the DC metering module do not detect voltage and current fluctuations at this time, it can be determined that the wireless communication module is faulty; if the AC metering module and the DC metering module detect voltage and current fluctuations at this time, it can be determined that the loss of connection is caused by voltage and current fluctuations.

[0039] Preferably, the present embodiment is further provided with a lightning protection module, which is electrically connected to the input end of the AC metering module to prevent thunderstorms from damaging the entire present embodiment.

[0040] The above is a detailed description of the embodiments of the present invention in conjunction with the accompanying drawings, but the present invention is not limited to the above embodiments. Even if various changes are made to the present invention, if these changes fall within the scope of the claims of the present invention and their equivalents, they still fall within the protection scope of the present invention.
