With the continuous improvement of people’s living standards, people’s demands for working and living environments are getting higher and higher. At the same time, the requirements for TCL LED Lighting systems are getting higher and higher, and the energy consumption in the field of lighting accounts for a large proportion of the total energy. Saving energy and improving lighting quality are imperative. Lighting electricity, as an important part of power consumption, already accounts for about 10% of electricity consumption. Traditional lighting technology has been strongly impacted. On the one hand, the development of information technology and computers has provided technical support for changes in lighting technology. On the other hand, due to the shortage of energy sources, countries are paying more and more attention to lighting energy conservation, and new lighting technologies can be rapidly developed to meet the requirements of energy-saving energy, comfort and convenience.
Lighting devices in a park in Austria are equipped with acoustic sensors, which is designed to counter anti-social behavior at night and increase security.
The park is located in the city of Graz. Six outdoor lighting fixtures in the park are equipped with motion detectors and noise sensors. Four of them are fitted with motion detectors and the other two are equipped with noise sensors. The dimming is set at 20% of the standard level.
When one of the motion detectors senses any type of motion, dimming will immediately increase to 50%. If one of the noise sensors senses any noise, the lumen raises the area's lighting to 100%.
When the sun goes down, the light level will be accompanied by the entire process of pedestrians walking. When the pedestrian passes by, the front light will turn on, and the light behind will darken again after a certain period of time.
Therefore, any activity in the park can be immediately perceived, thus making pedestrians feel safer.
The lumen is controlled by an intelligent, networked lighting control system that activates the lumen via the radio module when the sensor detects noise or motion
The accompanying software also shows the energy savings achievable with the new lighting solution, as the pilot project currently saves about 60% of energy compared to the original lighting fixture. A nearby gateway can communicate between the fixture and the web server.
The control system can also support the collection of information on a number of elements, including noise levels, weather conditions, and personnel mobility.
Analyzing these data may eventually provide more useful opportunities. Siegfried Nagl, the mayor of Graz, said, “This project shows how we brought the park into the digital age. In doing so, we can maximize safety.” “Since the installation of new lamps, there has been no destructive behavior again.
