In response to the limitations of traditional wired and mechanical lighting control methods, this paper introduces an intelligent LED lighting control system based on Internet of Things (IoT) technology. By embedding an intelligent control module within the LED lighting terminal, the system integrates advanced technologies such as embedded systems and wireless sensor networks. This approach enables smart, digital, and wireless control of lighting, while also allowing real-time monitoring of environmental factors like temperature, humidity, and ambient light levels.
Overview
As LED lighting becomes more widespread and mobile internet technology continues to evolve, there is a growing demand for networked, intelligent, and energy-efficient home solutions. Smart devices such as household appliances, lighting fixtures, and security systems are increasingly being integrated into centralized control platforms for seamless intelligent management and control.
With the rapid growth of the IoT industry, smart LED lighting has become a key component in modern smart homes. This paper presents an intelligent LED lighting control system designed to support the concept of "Green Smart Lighting." Utilizing IoT and embedded technologies, it allows for wireless remote control of various lighting modes, along with real-time monitoring of ambient illumination and the operational status of LED lamps.
Additionally, the system employs sensor technology to automatically adjust lighting intensity and switch between different color temperatures, creating a comfortable, energy-saving, and safe lighting environment. As shown in Figure 1:
System Hardware Design
The hardware design of the system consists of two main components: the LED lamp control terminal and the touch panel, both of which work together to provide intelligent lighting control. The system includes a control module, communication module, LED driver module, and power supply module.
(1) Main Control Unit Hardware Design
The main control unit comprises two parts: the LED lamp control terminal and the data acquisition terminal. The LED lamp control terminal is built around an ARM-based STM32 microcontroller, supported by a power supply circuit, peripheral circuits, and an illumination sensor. The data acquisition terminal includes sensors for temperature, humidity, illuminance, and PM2.5. A schematic of the hardware circuit is shown in Figure 2:
(2) Touch Panel Hardware Design
The touch panel is based on the STM8S series ARM processor, which includes a built-in touch library for capacitive sensing. It is used to control switches and adjust brightness, with the circuit schematic illustrated in Figure 3:
(3) ZigBee Wireless Communication Module Design
To enable centralized management and environmental monitoring, the system uses a ZigBee wireless communication module. The CC2530 module from Texas Instruments is employed, offering a low-cost, low-power solution with a 2.4GHz RF transceiver and an 8051 controller. This ensures reliable and efficient communication within the network.
(4) Power Module Design
Considering the use of the system in residential environments, where the primary power source is 220V AC, the power module is designed using discrete components to generate multiple regulated voltages. The 220V AC is first converted to 12V DC using a switching power supply. Then, the 12V is stepped down to 5V using the LM2576 regulator, and further to 3.3V using the AMS1117. The 5V and 3.3V power supply schematics are shown in Figures 4 and 5 respectively:
System Software Design
The software design focuses on collecting and transmitting data related to LED lighting and environmental conditions. Through the ZigBee wireless network, the system supports centralized control and data collection, enabling efficient management of LED lighting systems.
Conclusion
Through the integration of theoretical knowledge and practical implementation, this paper presents a system that adjusts LED brightness and color based on environmental conditions. By incorporating light and motion sensors, the system achieves intelligent, digital, and networked lighting. The design is both functional and scalable, effectively reducing energy consumption and offering significant value for future smart home applications. With its promising performance and adaptability, this system has great potential in the growing IoT market.
