An occupancy sensor is an electronic device that is used for motion detection. It contains an electronic microwave-beam device which quantifies motion and can either be integrated with or connected to other devices which alert the user of the presence of a moving object that is within the field of view of the sensor.
The use of occupancy sensing is a key component to aid further-reduced energy bills and contribute to the reduction in environmental light pollution.
They can be introduced for use in public and private street lighting and car parks, urban and landscape area lighting and for pathways and cycleways.
MAXIMAL SAFETY, MINIMAL ENERGY.
The goal is how to resolve the challenge of safely illuminating roads and public spaces whilst at the same time reducing energy consumption during times when there is reduced vehicular or pedestrian traffic respectively.
With sensor dimming control, traffic and pedestrian safety is not compromised whether they are heavily trafficked or quiet. The feeling of safety and security is maintained throughout the public realm, but aligned with the prevailing usage density and specific task distance needs. Good, correct lighting through the aid of accurately applied and programmed controls, sets the appropriate lighting levels and ensures violence and crime prevention as well as the promotion of wellbeing.
Changes the the night-time environment caused by humans can disturb the delicate, vital balance of our ecosystem. An unchecked increase in environmental light pollution is undoubtedly playing a detrimental role. Long before night falls public lighting is activated and often remains so throughout the night. This inherently delivers an unnatural illuminated night-time visual environment. According to researchers this can affect both plant growth as well as insect and foraging animal behaviour, disrupting the local flora and fauna ecosystems. When artificial lighting is not required it is beneficial to all to dim levels as much as feasible. This is good for biodiversity, good for the climate and good for the environment.
