Our open communication protocol allows easier integration with other third party intelligent platforms and IoT devices, ensuring your intelligent street lighting system is the nerve center of the smart city.

Key Characteristic:

Intelligent Remotely Street Lights Management

Smart city street lighting management software gives you full command over your entire public lighting infrastructure. Monitor and control each individual street light or group of street lights and entire city lighting points with an open, secure and intuitive dashboard, remotely accessible through a standard web browser at any time, from anywhere as long as there is internet. Optimization workflow leads to maximum energy efficiency and flexibility on lighting management.

Our networked controls system is based on two-way communication. The intelligent street light control system enables individual streetlight points to be controlled and monitored remotely and to be centrally managed via our server (online web application platforms). City managers and street lighting operators can remotely control the outdoor lighting infrastructure by setting on-demand dimming levels to achieve significant energy savings and get real-time feedback, reducing operating and maintenance costs via accurate scheduling of on-site tasks, while improving both reliability and energy efficiency.

Citywide Street Light Infrastructure Control & Overview

Creating group or individual street lights controlling. Adjust citywide lighting requirements based on profiles, specific weather with scene lighting mode (snowing/foggy/storm days), certain events, or vehicle moving and human movement for adaptive dimming. Highway, street, garden, parking lot, and underpass with specific scenes. Modern street lighting systems are mainly integrated with high output efficiency LED street lights (luminaires), high sensitivity motion sensors and ambient sensors, individual light controller, intelligent cabinet as centralized controller/feeder pillar, and the cloud based online web application server.

Faults Monitor & Proactive Maintenance

Identify street light alerts/alarms on Google map at a city-level. Precise location for maintenance crews promptly action and reduce extra inspection expenses. Faults reporting & alert in real-time for active maintenance. Abnormal cabinet door open, outage, cable leakage, lamp failure, grid/lamps status, malfunctions and other system issues automatically notify with data-rich alarms on monitoring center.

Optimization Energy & Reporting

Daily, monthly, yearly power consumption and saving reporting with insightful graphical data of each cabinet or entire city helps optimize the entire lighting infrastructure. Efficient energy optimization by rich visualization data and maintenance planning and logs activity. City energy consumption overview helps make actionable plans to meet smart city goals.

Segment Control Panel (Feeder Pillar) for Street Light Control System

Smart lighting system controls at segment-level up to 1,000 lamps (quantity depends on site transformer distance). Typically around 100 units by PLC communication channel; LoRa communication can be around 130 streetlights within 1km radius multi-direction with data transmission across transformers. The feeder pillar receives data from lamps, manages and transmits data to a secure cloud based server.

Intelligent Street Lighting Cabinet is the nerve center and key element of smart LED street lighting. The smart CPU (CC800), installed inside control cabinets, offers advanced grid monitoring and group control functions: detect grid power failures, cable breakages, leakages, theft detection, cabinet door opened/closed, faulty reporting and energy consumption reporting, and synchronizes street lights data to monitoring center. Even if disconnected from the internet, it can operate autonomously for weeks, deriving switching points from typical light intensity profiles stored in the astronomical calendar, and processing additional I/O and energy measuring devices.

Individual Lamp Level Controlling & Monitoring

Intelligent street lighting system controlled at segment-level comprises a cluster of up to 256 street lights that communicate to a power cabinet for automatic on/off/dimming control. The feeder pillar receives data from street lamps and transmits them to the cloud based server for dashboard display.

Individual lamp control is handled via a luminary controller which provides lamp-level functionality: remote on/off/dimming, status monitoring, electrical parameters feedback, malfunction reporting, and optional sensors (light, temperature, humidity, noise, pollution, etc.). The lighting grid can also power other smart city applications: EV charging, weather/ambient sensors, advertising screens, manhole cover management, fire alarm, motion sensors, CCTV video surveillance cameras, and traffic flow detection cameras.

Lowering City Lighting Infrastructure Cost

Limit energy consumption and minimize CO2 emissions and light pollution with target dimming schedules and motion/ambient sensor networking. On-demand lighting schedules achieve sustainability without compromising comfort and safety. Fundamentally lowers maintenance costs and operating expenses.

Amazing & Safer Lighting Experience with Sensor Networking & Adaptive Lighting

Ensure precise illuminance and security lighting at the right place by adjusting schedules per needs with accurate, transparent lighting data. Increase light levels in busy areas or unexpected events. Workflow management tools improve decision-making with performance insights. Automatic fault notifications support prompt repair and reduce complaints.

Adjustable Street Light Colors (2700K ~ 6000K)

Create the right ambience to improve driving safety and citizen comfort. Street light color temperatures can automatically change for specific weather such as snowing days, foggy areas, and storms: CCT can shift (example 4500/6000K to 2700K) from daylight/cool white to warm white, triggered by dense fog, rainstorm, snowing, or combined CCT compensation in tunnels, based on ambient sensor networking.

Multi-Communication Channels to Solve Harsh Working Environments

Power line communication enables data transfer over existing powerlines.

LoRa advantage: data transmission across transformers

Smart City Integration

Traffic flow, security systems, environment sensors, EV charging, emergency response systems, weather systems, advertisement billboards, asset management, digital parking lots, etc. Manage and control different smart city devices and IoT applications with a single centralized management dashboard.
