Sansi LED: Sustainable LED Lighting and Integrated LED Display

I. Role Evolution: From Single Facility to Urban Neuron

Traditional street lights, once isolated illumination devices, are being redefined by smart street lights. Equipped with environmental sensors, edge computing units, and communication modules, these "intelligent terminals" now serve as urban nerve endings—collecting real-time data on public space conditions. For example, pedestrian flow heatmaps from smart street lights have enabled dynamic sanitation route adjustments, showcasing their potential as governance tools.

Smart Street Lights in Hangzhou Qianjiang Century City

During the G20 Summit held in Hangzhou in September 2016, the smart street light system installed by Sansi in Qianjiang Century City, the venue of the G20 Summit, showed to guests from all over how to use street light poles as carriers and new-generation information technologies such as big data, cloud computing, the Internet of Things, geographic information, and mobile Internet as driving forces to establish an intelligent and sustainable urban development model. 

II. Technology Integration: Building a Trinity Capability System

Perception Layer Innovation

Integrated with environmental monitoring components such as PM2.5 and noise sensors, some devices are equipped with AI cameras (after desensitization) for identifying events such as street vending and abnormal manhole covers, forming a "capillary-level" perception network for urban management.

Platform Layer Collaboration

After connecting with the city's brain system, street light data can coordinate cross-departmental business processes such as traffic signal regulation and emergency department response. One district in Shenzhen once used street light IoT data to automatically generate a tree reinforcement plan before a typhoon.

Service Layer Extension

By equipping Wi-Fi hotspots, charging interfaces, and other convenience facilities, some cities are piloting the transformation of light poles into service nodes for a "15-minute living circle," enhancing the utilization efficiency of public resources.

III. Governance Reinvention: Creating a New Urban Operation and Maintenance Paradigm

Problem Discovery Mechanism: From passively receiving complaints to actively issuing warnings, street light sensors can significantly improve the efficiency of road detection.

Resource Scheduling Mode: Based on dynamic analysis of light intensity, pedestrian, and vehicle flow, precise allocation of municipal electric power resources can be achieved.

Public Participation Path: Functions such as scanning a QR code to provide feedback on lighting comfort create a positive interaction loop between "government-facility-citizen."

IV. Future Outlook: Basic Components of a Digital Twin City

With the development of 5G-A and vehicle-road coordination technology, smart street lights may become spatial coordinate points for a digital twin city. Equipment such as millimeter-wave radars loaded on them can provide high-precision positioning references for autonomous driving. Meanwhile, continuously accumulated spatio-temporal big data will help deeply explore the operating laws of the city. This evolution path of "one pole with multiple functions" vividly illustrates the service characteristic of new infrastructure that "empowers without defining."
