Smart public lighting: from control at the electrical cabinet to the light points
Smart public lighting is no longer a technological utopia: it is a major lever for energy transition for local authorities. Thanks to connectivity, it is now possible to optimise consumption, reduce maintenance costs and improve residents' comfort.
Deux approches se complètent : le pilotage à l’armoire, avec la solution Radiolite de BH Technologies, et le pilotage aux points lumineux, via nœuds communicants connectés. Ensemble, elles redéfinissent la gestion de la lumière urbaine.
Control cabinet management, the backbone of smart public lighting
A connected cabinet for centralised management
Radiolite 4XX, developed by BH Technologies, modernises street lighting cabinets by adding computing and communication intelligence.
Its socio-astronomical clock automatically adjusts switching times according to the season, local needs and real-time data. The result: precise control and immediate energy savings.
Performance supervision and monitoring
Combined with the supervision module BH Gate and at Luce, Radiolite transmits information on consumption, status and alerts from the cabinets. Technical teams can view anomalies, schedule interventions and adjust schedules without having to travel. This monitoring transforms data into action, providing a real energy dashboard for local authorities.
Benefits for the local authority
- Measurable reduction in consumption and operating costs.
- Simplified maintenance thanks to remote monitoring.
- Complete traceability of energy data for accurate reporting.
Light point management: precision, adaptability and extended services
Why choosing light points?
While cabinet control provides overall management, point-of-light control takes efficiency even further.
Each light fixture becomes autonomous at the communicating nodes, such as our BH Nodes on a mesh network, in Zhaga. These devices control public lighting, detect faults, adjust brightness according to presence and communicate in real time with Luce.
Key figures and energy savings from smart public lighting
- LEDs already reduce energy consumption by around 50 to 70 per cent compared to older lamps.
- By opting for smart public lighting, savings can reach up to 80% according to studies by the Smart Cities Marketplace andUbicquia.
Services beyond lighting
Lighting is becoming a true digital infrastructure:
- Dynamic intensity adjustment (security, events, variable schedules).
- Reduction of light pollution and improvement of night-time comfort.
- Predictive maintenance based on alerts for each individual light fixture.
- Possible integration of other sensors (air, noise, parking, public Wi-Fi).
Direct benefits for local areas
- Sustainably reduced energy bills.
- Scheduled and lower maintenance costs.
- Improved safety and sense of well-being.
- Tangible contribution to energy efficiency and climate goals.
Smart public lighting, tailored to each local authority
Smart public lighting does not impose a single model: it adapts to the needs and ambitions of each community.
Some will choose cabinet-based control, which is ideal for obtaining an overview of the network and achieving rapid gains across the entire fleet. Others will opt for more precise light point control, designed for sensitive or high-traffic areas where responsiveness and quality of service are paramount.
These two approaches are not mutually exclusive, but rather complementary. It is a detailed understanding of the territory, its uses and energy objectives that determines the right balance.
By combining technical intelligence and territorial strategy, local authorities are gradually building a network of lighting that is energy-efficient, scalable and sustainable — a network that provides better lighting, consumes less energy and contributes to the transformation of a more harmonious and responsible city.
