Most municipalities do not work in a uniform lighting infrastructure.
In many cases the task is to manage a mixed installation of old luminaires such a High Pressure Sodium Lights, older generations of LED lights and LED lights which are Zhaga/NEMA-ready – all at the same time.
A mixed infrastructure makes it difficult to apply one single control strategy everywhere. It should be possible to modernise step by step without having every luminaire to be replaced.
Progress slows down if smart lighting requires a perfect starting point. A practical solution must work with the infrastructure the city has today and prepare each upgrade for what comes next.
All luminaires in the city does not have the same technical capability. Where some can be individually controlled through e.g. Zhaga controllers other can not. Therefore they cannot be managed in the same way.
Different areas in the city can be managed according to their actual control level, data quality and operational value.
The city can use the appropriate level of control across the estate – from group-level management to individual luminaire control – while bringing all levels into one shared operational view.
Information about luminaires, cabinets, feeder groups, control capabilities and installation history may be incomplete or spread across different systems and documents.
Assets can be organised in a physical and logical hierarchy that shows what is installed, where it belongs, how it is connected and what level of control it supports.
The municipality gains a clearer understanding of the lighting infrastructure, providing a stronger basis for operation, procurement and future investment.
Upgrades may be driven by individual projects, urgent replacements or local requirements without a clear overall strategy.
The municipality can decide where cabinet control is enough or where luminaire-level precision is justified.
The infrastructure can be upgraded over time without forcing unnecessary replacement
The cabinet controller provide segment-level control and monitoring across the whole lighting estate independent of capabilities of the luminaires.
As luminaires are upgraded to support Zhaga or NEMA controllers you allow for individual control and management of the streetlights.
Where control for some reason needs to be placed external to the luminaire, alternative DALI/D4i-based control solutions are available .
GreenStreet vision helps managing different asset types in one operational view so a mixed infrastructure becomes easier to understand.
Manage your mixed infrastructure from day one and evolve in to more precise control of the luminaires at your pace.
Explore how GreenStreet helps municipalities manage mixed lighting estates — from cabinet-level operation to luminaire-level precision where it creates value.
