What Is Intelligent Street Lighting?

Intelligent street lighting turns every luminaire into a controllable, measurable city asset. By combining smart street lights, multi-purpose smart poles, standards-based controllers (NEMA or Zhaga), robust communications, and the Smart City Control System (SCCS), municipalities cut energy use, improve safety, and unlock new services—on grid or with a solar smart street light network.

What Is Intelligent Street Lighting?Intelligent street lighting is a connected LED lighting system where each luminaire or pole can be monitored and controlled remotely. The network applies adaptive dimming, sensor-based automation, and real-time fault diagnostics to deliver bright, uniform illumination only when and where it’s needed. It reduces electricity bills, enhances road safety, and streamlines maintenance for public works teams.

Core capabilities

  • Remote on/off, scheduling, and multi-level dimming
  • Live status, power metering, and fault alarms
  • Occupancy and ambient-light response for context-aware lighting
  • Integration with cameras, environmental sensors, Wi-Fi, and EV charging

Key components

  • LED luminaires with roadway optics and surge protection
  • Smart drivers and plug-and-play controllers (NEMA or Zhaga)
  • Communications (LoRa-MESH, PLC, 4G/LTE, RS485)
  • Central management via SCCS

Why Intelligent Lighting Matters Right Now

Energy & Cost

LED efficacy + dimming schedules + sensor logic often cut energy use by 50–70% vs. legacy lighting, decreasing OPEX and payback time.

Safety & Experience

Better uniformity, fewer dark spots, and adaptive brightening during peak activity improve comfort for drivers and pedestrians.

Sustainability

Lower energy and longer lifetimes reduce carbon footprint. With solar smart lighting, corridors can run fully off-grid.

System Architecture & Building Blocks
1:LED Luminaires & OpticsHigh-efficiency LED engines paired with roadway optics deliver target illuminance and uniformity while minimizing glare. Specify CCT, CRI, surge levels, corrosion class, and ingress protection for your climate and road classes. Explore our smart street light options.
2:Smart Drivers & Dimming InterfacesStreet light drivers provide constant current and support 0–10V or DALI/D4i dimming. They enable smooth, reliable control from the attached controller and protect against grid disturbances.
3:Controllers & SocketsControllers turn each light into an addressable node. On AC/grid projects, the NEMA single-lamp controller is the fastest retrofit path. On new or solar builds, compact Zhaga (Book 18/D4i) controllers offer low-voltage power and standardized data models.
4:Gateways & CommunicationsDepending on coverage and IT policies, choose LoRa/LoRaWAN (low-power wide area), PLC (over the power line), 4G/LTE or NB-IoT (cellular), or RS485 (wired for tunnels).
5:Central Management PlatformThe Smart City Control System (SCCS) maps devices, pushes schedules, tracks energy, raises alarms, and integrates with third-party systems—on web, tablet, or mobile.

Controllers: NEMA vs. Zhaga (and Where Each Fits)

Aspect NEMA (ANSI C136.41) Zhaga (Book 18 / D4i)
Best use case AC/grid retrofits on existing LEDs New LED or solar fixtures needing compact control
Electrical interface 3/5/7-pin twist-lock; 0–10V/DALI dimming Low-voltage 4-pin; D4i accessory power & data
Size & placement Larger (contains high-voltage stages) Smaller; mounts neatly on luminaire top/side
Interoperability Broad with legacy drivers Strong in D4i ecosystems; future-proof data
Example product NEMA Single-Lamp Controller Wireless Zhaga Controller (Solar/LoRa-Mesh)

Communication Options for Citywide Control

LoRa-MESH

Long-range, low-power. Ideal for large areas with sparse power availability at gateways. Backhaul via fiber or 4G/LTE.

PLC (Power Line Communication)

Uses existing power cables for data, reducing RF planning. Works well on continuous feeders, such as highways or boulevards.

4G/LTE / NB-IoT

Fast to deploy using cellular networks. Great for pilots, distributed sites, or where LoRa/PLC coverage is constrained.

RS485 (Wired)

Deterministic and robust for short, controlled runs—common in tunnels, depots, or enclosed sites.

AC vs. Solar Smart Lighting (SSLS)Intelligent lighting works on the grid—and off it. With a Solar Smart Light System, each pole integrates PV panels, batteries, and an MPPT charge controller to run autonomously. For solar projects, Zhaga/D4i controllers and low-voltage drivers pair well with energy-aware logic.

AC/Grid Advantages

  • Quick retrofit with NEMA controllers
  • No battery lifecycle to manage
  • High power availability for demanding optics

Solar (SSLS) Advantages

  • No trenching or metering; ideal for remote roads
  • Resilient during grid outages and disasters
  • Green branding and ESG impact

Smart Poles: From Lighting to City Platforms A smart pole is more than lighting. It’s a modular platform for cameras, environmental sensors, Wi-Fi access, public speakers, emergency call points, digital signage, and even EV charging. One structure, many services—managed through SCCS.

  • Public safety: CCTV, SOS intercom, incident alerts
  • Connectivity: Wi-Fi APs, small cells, backhaul radios
  • Citizen engagement: LED signage for info and alerts
  • Sustainability: Optional solar kits and EV charging bays

Design & Deployment Workflow (incl. DIALux)
  1. Baseline audit: Count poles, feeder circuits, lamp powers, fault logs, and energy tariffs. Set KPIs (energy, uniformity, uptime).
  2. Lighting design: Request a free DIALux design with IES files to meet roadway classes and glare limits.
  3. Product selection: Choose wattages, optics, CCT, corrosion class, surge rating, and controller standard (NEMA or Zhaga).
  4. Communications plan: LoRa, PLC, LTE, or hybrid—document gateway density and backhaul.
  5. SCCS provisioning: Register devices, create groups, configure dimming scenes, and assign user roles.
  6. Pilot & tune: Deploy a district, validate photometrics, test alarms, and optimize schedules by traffic profile.
  7. Rollout & training: Scale citywide with installation playbooks, O&M manuals, and cybersecurity policies.
  8. Reporting: Track energy, CO₂ avoidance, uptime, and ROI; iterate seasonally.
