Zigbee Wireless LED Street Light is a type of smart and energy-efficient outdoor lighting system that uses the Zigbee protocol to communicate and control the LED lights. Zigbee is a low-power, low-cost and reliable wireless network that can connect multiple devices and sensors in a mesh topology. Zigbee Wireless LED Street Light can offer many advantages over traditional lighting systems, such as:
- Remote monitoring and management: The status and performance of each LED light can be monitored and managed through a web-based platform, which can display the real-time data, fault detection, energy consumption and other information. The operators can also adjust the brightness, color, timing and other parameters of the LED lights remotely, according to the traffic, weather and environmental conditions.
- Energy saving and cost reduction: The LED lights can be dimmed or switched on/off automatically based on the preset schedules or the feedback from the sensors, such as motion sensors, light sensors, temperature sensors and so on. This can reduce the power consumption and extend the lifespan of the LED lights. Moreover, the Zigbee protocol can reduce the wiring and installation costs, as it only requires a two-wire bus for communication.
- Flexibility and scalability: The Zigbee Wireless LED Street Light system can be easily expanded or modified by adding or removing devices and sensors, without affecting the existing network. The Zigbee protocol can also support different types of LED lights and controllers from different manufacturers, ensuring compatibility and interoperability.
The basic components of the system for Zigbee wireless LED Street light are:
- LED Street Luminaire with NEMA 7 pin socket: This is the LED light fixture that has a NEMA 7 pin socket at the bottom, which can connect to a lighting controller. The LED light can have different wattages, color temperatures, color rendering indexes and photometric types, depending on the application and requirement.
- Lighting controller: This is a device that attaches to the NEMA 7 pin socket of the LED light, and acts as a Zigbee node. The lighting controller can receive and send signals from/to the gateway or other nodes, and control the current and voltage of the LED light. The lighting controller can also have sensors built-in or connected externally, such as motion sensors, light sensors, temperature sensors and so on.
- Gateway: This is a device that acts as a coordinator of the Zigbee network. The gateway can connect to the internet via Ethernet or cellular network, and communicate with the web end interface or software platform. The gateway can also communicate with the lighting controllers or other nodes via Zigbee protocol, and relay the commands or data between them.
- Web end interface or software platform: This is a user-friendly web-based platform that allows the operators to monitor and manage the Zigbee Wireless LED Street Light system. The platform can display the map of the lighting network, the status and performance of each LED light, the energy consumption analysis, the strategic management, the report management and the basic information setting.
- The gateway establishes a Zigbee network with the lighting controllers or other nodes, forming a mesh topology. The gateway assigns an address to each node, and creates groups and scenes for different lighting scenarios.
- The web end interface or software platform sends commands or data to the gateway via internet, such as setting up schedules, dimming levels, color temperatures and so on. The gateway forwards these commands or data to the corresponding nodes via Zigbee protocol.
- The lighting controllers or other nodes receive these commands or data from the gateway or other nodes via Zigbee protocol, and execute them accordingly. For example, adjusting the current and voltage of the LED light, switching on/off the LED light, dimming or changing color of the LED light and so on.
- The lighting controllers or other nodes also collect data from their own sensors or external sensors via Zigbee protocol, such as motion detection, ambient light level, temperature and so on. These data are sent back to the gateway or other nodes via Zigbee protocol.
- The gateway collects these data from the nodes via Zigbee protocol, and uploads them to the web end interface or software platform via internet. These data are processed and analyzed by the platform, and displayed in various forms for monitoring and management purposes.
