RS485 Smart Street Light Solution – Stable Wired IoT Lighting Control For Tunnel
RS485 Smart Street Light Solution – Stable Wired IoT Lighting Control
Reliable RS485 wired smart street light system for tunnels and industrial areas. Features interference-free communication, 3km transmission range, and centralized control. Supports PWM/0-10V dimming.
Key Features & Advantages of RS-485 Smart Lighting Solution
Interference-Free Stability: Unlike wireless systems (Zigbee/LoRa), the wired RS485 connection is immune to radio frequency interference, making it the top choice for critical infrastructure like tunnels.
Long-Distance Transmission: Supports a communication range of up to 3 km within city areas, extendable via signal controllers.
High Capacity: A single system loop can manage up to 5,000 terminal controllers using cascaded signal repeaters.
Precise Control: Real-time ON/OFF switching and 0-10V/PWM dimming for maximum energy efficiency.

RS485 Smart Lighting Solution
Product Item: BJX Series Street Light 200W, RS485 Solution, Center controller and Lamp controller
Quantity: 120pcs
In March 2021, Gebosun successfully deployed the RS485 Smart Lighting Solution for a government project in Chile. The project involved 120 units of BJX Series 200W Street Lights managed by our RS485 centralized and lamp controllers. The client reported exceptional stability and significant maintenance savings, validating the system's performance in real-world conditions.
FAQs About RS485 Smart Street Lighting Solution
Why should I choose RS485 over wireless solutions like LoRa or Zigbee?
RS485 is recommended for environments with high electromagnetic interference (like factories) or physical barriers (like tunnels) where wireless signals might be blocked or unstable. It provides the most reliable, "hard-wired" communication link for critical lighting safety.
Do I need to install extra data cables for the RS485 solution?
Yes. Unlike our PLC (Power Line Communication) solution, the RS485 system requires a dedicated twisted-pair data cable (typically 2-core shielded wire) connecting the controllers. This ensures dedicated bandwidth and signal integrity separate from the power line.
What is the maximum distance supported by the RS485 system?
The system supports a transmission distance of up to 3 kilometers in typical city scenarios. For longer distances or complex layouts, we use the BS-RS803 Signal Controller to repeat and boost the signal, extending the reach effectively without data loss.
Can the system measure energy consumption?
Yes. The BS-RS812R Single Lamp Controller has built-in power metering capabilities. It can remotely read and report voltage, current, power factor, and accumulated energy consumption to the SCCS (Smart City Control System), allowing for precise energy audits.
