[0025] To make the objectives, features, and advantages of this disclosure more apparent and understandable, the technical solutions in the embodiments of this disclosure will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this disclosure, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this disclosure without creative effort are within the scope of protection of this disclosure.

[0026] Combination Figure 1 and Figure 2 As shown, the LoRa-based floodlight provided in this embodiment includes: a floodlight unit 2, a LoRa unit 3, a control unit 4, and a backend management unit 7. The floodlight unit 2 includes a housing 1, and both the LoRa unit 3 and the control unit 4 are disposed in the housing 1. The control unit 4 is communicatively connected to the floodlight unit 2 through the LoRa unit 3 for adjusting commands. The backend management unit 7 is connected to the control unit 4 to realize remote status monitoring. The LoRa-based floodlight provided in this embodiment has the following advantages: long transmission distance, wide signal coverage, and strong penetration capability; fewer supporting transmission devices and a simple network architecture; lower maintenance workload and more stable and reliable operation; in addition to lamp control, it can integrate various IoT sensing devices to achieve the Internet of Things.

[0027] Optionally, the housing 1 has a receiving cavity in which both the LoRa unit 3 and the control unit 4 are disposed.

[0028] The floodlight unit 2 may include an LED light source, a driving circuit and a heat sink housing 1. The housing 1 integrates a LoRa unit 3 and a control unit 4.

[0029] LoRa Unit 3 can be composed of a LoRa spread spectrum module (transmitter) and a LoRa control terminal (receiver), supporting low-power long-distance communication.

[0030] Control unit 4 may include a storage module (storing brightness strategies, schedules, etc.) and a control module (executing logical judgments and issuing commands). Control unit 4 may also be an edge controller.

[0031] The back-end management unit 7 may include a cloud or local server platform, and communicate with the control unit 4 through a LoRa gateway to achieve remote monitoring and management.

[0032] In some specific implementations, the control module sends a dimming command via the LoRa spread spectrum module → the LoRa control terminal receives the command → the dimmer 5 adjusts the brightness of the LED light source. The human body sensor 6 detects an activity signal → the signal is transmitted to the control module → triggering a preset "nighttime human body sensing mode" (e.g., turning on floodlights and maintaining this for 30 seconds). The background management unit 7 issues a switch command → the command is transmitted to the control unit 4 via the LoRa gateway → the control module executes the command and provides feedback on the status.

[0033] The housing 1 can be a waterproof and dustproof housing 1, with a reserved sensor interface (such as RJ45 or wireless interface) inside.

[0034] LoRa communication can be implemented using the SX1276 chip for spread spectrum communication, with a communication distance of up to 3km (line-of-sight environment). Dimmer 5 can be a PWM dimming circuit, supporting 0-100% stepless dimming.

[0035] In some specific implementations, a sensor is also included, which is connected to the control unit 4.

[0036] In some specific implementations, a dimmer 5 is also included. The output of the control unit 4 is connected to the input of the LoRa unit, the output of the LoRa unit is connected to the input of the dimmer 5, and the output of the dimmer 5 is connected to the input of the floodlight unit 2. The output of the control unit 4 is connected to the LoRa spread spectrum module, and the LoRa control terminal communicates with the spread spectrum module via the 470MHz frequency band. The dimmer 5 receives the PWM signal output by the LoRa control terminal and performs 0-100% linear dimming of the LED module of the floodlight unit 2 according to the duty cycle. Specifically, the background management unit 7 can preset multiple brightness scenes, which are then processed by the control unit 4 to generate corresponding dimming commands.

[0037] In some specific implementations, the Lora unit includes a Lora spread spectrum module and a Lora control terminal. The input of the Lora spread spectrum module is connected to the output of the control unit 4, the Lora control terminal is wirelessly connected to the Lora spread spectrum module, and the output of the Lora control terminal is connected to the input of the dimmer 5.

[0038] In some specific implementations, the sensor includes a human body sensor 6. The sensor can be installed outside the floodlight housing 1 and connected to the control unit 4 via an RS485 interface. When the human body sensor 6 detects an activity signal, it triggers the control unit 4 to send a lighting command to the floodlight unit 2 and transmits the trigger record back to the background management unit 7 via the LoRa unit 3.

[0039] In some specific implementations, the control unit 4 includes a storage module and a control module. The storage module is wirelessly connected to the management unit, and the input of the control module is connected to the output of the storage module. A time zone strategy table can be pre-stored in the storage module of the control unit 4. The control module automatically switches between day and night modes based on the location information obtained by the GPS module. Users can remotely activate the emergency mode through the web interface of the backend management unit 7. In this mode, the control module will ignore the dimmer 5 signal and directly control the floodlight unit 2 to enter 100% brightness.

[0040] In some specific implementations, the control module is equipped with a remote switch mode to deal with emergencies, and the priority of remote control is greater than that of intelligent control, so that timely countermeasures can be taken when the intelligent system fails.

[0041] In some specific implementations, the LoRa unit 3 includes at least one LoRa gateway, and multiple floodlight units 2 are connected to each LoRa gateway. Each LoRa gateway is connected to the control unit 4. The collected ambient illuminance information is transmitted to the control unit 4 via wireless communication between the floodlight units and the LoRa gateway, enabling the control unit 4 to acquire ambient illuminance information in the target area. Alternatively, the ambient illuminance acquisition device can be independent of the floodlight units 2 and can be directly connected to the LoRa gateway. The collected ambient illuminance information is then directly transmitted to the control unit 4 via the LoRa gateway, enabling the control unit 4 to acquire ambient illuminance in the target area. Multiple floodlight units 2 are positioned at preset locations in the target area. The use of LoRa wireless communication cloud control for the floodlight units 2 significantly improves performance in terms of luminous efficacy, illumination uniformity, color rendering index, lifespan, and light decay. The floodlight units 2 controlled by the LoRa unit 3 achieve optimal energy savings and enable IoT, data acquisition, and control center feedback functions.

[0042] In some specific implementations, a brightness monitoring module is also included, which is connected to the control unit 4. This brightness monitoring module may include a photosensitive sensor array to collect ambient illuminance data in real time and feed it back to the control unit 4. The control module dynamically adjusts the output of the dimmer 5 according to a preset illuminance threshold (e.g., 50 lux), and automatically increases the brightness of the floodlight to a preset safety level when the ambient light is below the threshold.

[0043] The LoRa-based floodlight control system provided in this disclosure includes the LoRa-based floodlight provided in this disclosure. Since the LoRa-based floodlight control system provided in this disclosure has the same advantages as the LoRa-based floodlight provided in this disclosure, further details will not be repeated here.

For example, the steps described in this disclosure can be executed in parallel, sequentially, or in different orders, as long as the desired result of the technical solution disclosed in this embodiment can be achieved, and this is not limited herein.
