Ubiquitous smart street lights are no longer just a tool for lighting up the night but the most basic IoT terminal for smart cities, combining dozens of functions in one pole and supporting multiple services like urban lighting, security, environmental monitoring, and 5G signal coverage. A lot of people wonder what’s inside a small smart street light pole. Today, TIANXIANG will give you a detailed overview of the full structure of an all-in-one smart street pole from five core modules.
I. Basic Lighting Module
This is the most basic part of a smart street light pole; it mainly includes an LED light source, a driver power supply, and an intelligent dimming driver. This module has smart dimming components that can automatically adjust the brightness based on light intensity, traffic flow, and pedestrian flow, unlike traditional street lights with fixed brightness. At night, when there are few pedestrians, it reduces power and turns off during the day by itself. The heart of energy saving for smart street lights is the LED light sources, which decrease the energy consumption by more than 60% compared with traditional high-pressure sodium lamps.
II. IoT Control and Communication Module
It is the same as a smart street light pole’s brain and neural network. The main components are the intelligent gateway, the communication module, and the controller. The controller controls all external devices. The Gateway collects the data. Streetlight operation and environmental data are uploaded in real time to the cloud management platform of the city through 4G/5G and NB-IoT networks. The manager can control the light to turn on and off and troubleshoot the fault remotely without on-site inspections, thus achieving intelligent management of street lights in the whole area.
III. Multifunctional Sensing Sensor Module
Sensors provide sensing capabilities to all-in-one smart street poles. The most common elements are light sensors, temperature and humidity sensors, noise sensors, air quality sensors, and infrared human body sensors. As it monitors changes in PM2.5, noise, temperature, and humidity in real time, the device constantly collects data about its surrounding environment. The system also detects pedestrians and vehicles on the road and adjusts the brightness of the lighting in real time, offering data support for urban environmental management and traffic flow analysis.
IV. Security and Public Convenience Module
This module is based on the function of all-in-one smart street poles as public service facilities and adds high-definition surveillance cameras, a one-button emergency call system, a public address system, an LED information screen, and other functions. Cameras monitor road security and traffic status in real-time; the one-button emergency call allows citizens to directly contact the police center for emergency assistance; and the LED screens can show weather, traffic warnings, and government notices, which fill the gap of urban outdoor information dissemination.
V. New Energy and External Expansion Modules
These are mainly solar photovoltaic panels, energy storage lithium batteries, and charging pile interfaces. The photovoltaic panels absorb solar energy during the daytime and store it for the streetlights at night, further reducing the cost of municipal electricity. At the same time, the interfaces of new energy vehicles’ charging piles and 5G micro base stations are reserved so that one pole has multiple purposes, avoiding the phenomenon of repeated pole erection in the city and saving the municipal construction space and cost.
TIANXIANG all-in-one smart street poles are integrated with lighting, surveillance, security, and other features. Energy-saving; durable; supports customization and integration with cloud platforms; and rich experience in engineering implementation.
