Overview
IEC TR 63540:2024 - Lighting systems - Characteristics for selected outdoor applications provides a practical, non-prescriptive technical overview of outdoor lighting systems for three selected applications: outdoor parking areas, road and street lighting, and pedestrian & cycle pathways. The report describes system architectures, configurations, interfaces, communications, control strategies and core characteristics useful for designers, operators and suppliers of outdoor lighting and smart-city infrastructure.
Key topics
- System architecture - classification into standalone luminaires, autonomous systems and centrally controllable systems, with typical characteristics and use cases.
- Lighting pole configurations - standard luminaires for adaptive lighting and multi‑function lighting poles that host sensors, CCTV, speakers, EV chargers and signage to support smart-city services.
- Sensors and sensor mounting - motion/presence sensors, ambient light sensors, and other environmental sensors (weather, air quality, traffic monitoring, noise, parking availability, pole tilt, flood, UV). Sensors can be integrated into luminaires or connected via standardized interfaces (e.g., ANSI C136.41, IEC PAS 63421 → IEC 63494-2-1).
- Communication modules and protocols - overview of wired, wireless, and hybrid communications used for luminaire control, monitoring and CMS connectivity.
- Control strategies and characteristics - timer/astronomical time control, presence/motion-based dimming, adaptive lighting, remote configuration, luminaire monitoring and fault reporting.
- Examples - illustrative system architectures for parking areas, vehicle-oriented street lighting, and autonomous pedestrian/cycle path systems including energy‑saving scenarios.
Practical applications
- Energy-efficient adaptive lighting: dimming profiles based on presence, ambient light and time-of-day to reduce energy use and light pollution.
- Smart-city integration: multi-function poles enable co-located services (traffic monitoring, air quality sensors, EV charging, CCTV, public messaging) using shared power and communications.
- Asset management and monitoring: centralized management systems (CMS) for luminaire control, status monitoring and predictive maintenance.
- Safety and user-centric lighting: tailored lighting for vehicular traffic, pedestrian comfort, and cycle routes with presence-triggered boosts or zone-based control.
