Lamppost infrastructure and street lighting as a whole, are predestined to provide additional services and technologies to cities and their inhabitants. Street lighting is almost everywhere in a more regular pattern and it`s connected to electricity.
2017 the City of Cairns was building the "Natural Play Playground". This playground should encourage children to interact with nature; to explore and learn about their surroundings. The Concept is implemented in a 100% natural state. So the Problem was to integrate technological infrastructure with as little impact as possible to the local environment as well as for flora and fauna of the area.
First of all, there was the decision to illuminate the paths of the playground when the night falls in. To do that in an energy efficient way, LED technology was chosen. But even with LED luminaires it is a waste of energy when the luminaires are shining even if nobody is there. Next to that it is an impact to the live of local animals and their environment. So the luminaires have been equiped with an sensor which is detecting people and is able to differentiate them from animals. With this technology the light is dimming down to a low level of light when nobody or just animals are there. If somebody appears in the range of the sensor, the luminaires are increasing the level of light smoothly to 100%. After a while of no further detection they go back down to the programmed low level. This ensures, that there is only light by the time it`s really needed. Next to the positive effects on energy consumption and environmental impact, this is a positive contribution against light pollution. After the lighting concept was finished, it was a fact that there will be poles to carry the luminaires and that there will be electrical power 24/7. So it was obvious to use them for more than just…
