OB05 Controlling Lighting


This concept selection covers the considerations taken into account in the design decisions for controlling urban lighting. Urban lighting enhances social and traffic safety and is also an important element in the urban spatial quality, both in terms of design and of creating atmosphere. Urban lighting is increasingly being used to tackle criminal activities and deal with emergencies.

The national agenda for urban lighting and local policy plans specify sustainability as a determining factor. Energy savings and avoiding light pollution are primary goals.

This ‘Controlling Lighting’ design selection expresses the municipality’s vision on lighting and does not make any representations about the type of light sources or lighting plans. This concept selection outlines the preconditions for an open fitting of the lighting system in the LLS’ system architecture. It also gives the degree to which the relevant stakeholder wishes can be honoured.

The power supply concept and the lighting control must be defined in close consultation with OLC and a joint vision created. This collaboration is essential, not only in the area of technical specifications, but also for later phases in the areas of laying, asset management and maintenance, operation and experimentation.

Management summary

This management summary contains some crucial starting points (selections) that are described further in the document. The purpose of the table below is to clarify these starting points.

1Standardisation of lighting applicationAttempts to standardise the command language of lighting applications have not been successful to date (ALIS, Talq etc.). The choice fell on using an API to communicate among the various lighting applications and through APIs to communicate with the control layer.
2Standardising lighting control in accordance with the DALI protocolDALI protocol V2.0 is the de facto standard for controlling the electronic ballast through the Outdoor Lamp Controller (OLC). The analogue 1-10 protocol will be phased out gradually.
3Autonomous local controlIn light of the guarantee of the availability and reliability of the public lighting, the lighting control will be autonomous on site without interference from the network.
Control through the network will be used to configure the Urban Lighting and to issue special commands (‘override’), for example to put all the lighting to maximum capacity in emergencies.
4LAN communicationThe light masts are connected to each other through a Local Area Network to allow for configuration of the Urban Lighting, apply dynamic lighting and gather sensor details. Various technical solutions can be chosen for the LAN.
