Cities have ambitions and visions and use them to plan their development strategies. As a result, street lighting is becoming increasingly intelligent, not only are the various advantages of light management systems being used, but also completely new application horizons are opening up in the areas of connectivity and smart city.
The principle is very simple: streets or paths remain dark as long as nobody uses them. Once the sensors register movement of an object, the light intensity will be increased to the prommed lighting level. The next lamps will continuously be shining at a higher intensity. The light accompanies the road user on his way. After the programmed hold time, the lights go back into the energy-saving modus.
Light. When needed. As much as needed – even away from Home? Intelligent Street Light Controller makes it possible. For example Kanalstrasse in Brugg.
Minimal basic lighting ensures the optical detection of the road. Once a person or a vehicles is passing the detection area of a street lamp, light intensity is automatically increased to a higher level and a message is sent to the next two luminaires. Thus, a specified number of lamps will continuously be shining at a higher intensity in front of and behind a pedestrian or a vehicle, providing a high comfort lighting experience. The modern LED lights with the intelligent motion sensors are programmable and allow remote access via the IBB WLAN network. The benefits are easier maintenance for IBB, lower energy consumption and thus lower costs for the city, as well as greater safety for slow traffic.
All conventional street lamps in the canton of Bern used up a total of 17 gigawatt hours (GWh) per year. With the use of intelligently controlled LED lights, the energy consumption of every refurbished street lamp can be reduced by 80 to 95 %. Once all the luminaires have been switched to “light on demand” technology, the TBA saves 13 GWh annually. This roughly corresponds to the energy consumption of 25,000 single-family homes per year.
"Continuous light" was installed here on the edge of the Regional Garden Show in 2018th. The facility is designed to show visitors the possibilities of modern street lighting and is a prime example of energy-saving street lighting.
Mercury vapor lamps have to be retrofit.
The inefficient mercury vapor lamps will lose their CE marking from 2015 and will be withdrawn from the market. As a result, cities and municipalities have to modernize their street lighting. With vkw Contracting you can reduce electricity and maintenance costs by up to 80% and achieve significant CO2 savings.
