Smart street light saves 80% of energy

Delft Technical University (Delft University of Technology, TU Delft) The Netherlands is testing a smart street lighting system on campus, using less than 80% of the electricity that the current system is consuming. And also cheaper for maintenance service.

This system includes street lights with LED light, motion sensors and wireless communication systems. This technique allows blurring street lights when there are no vehicles and people passing by. Wireless connections between street lights and a control room are possible. The lighting system was developed by an alumnus of the school, Chintan Shah, who won the first prize in a 2010 Technical Management competition with this study to improve energy efficiency on the university campus. .

Save 80% of electricity

The Netherlands has to pay 300 million euros per year for street lighting power consumption. The street lamp network also emits 1.6 million tons of CO ₂ per year. Street lamps must always be at the maximum level of light, even if there are no people in that area. Compared to current street lighting systems, Chintan Shah's intelligent system can reduce electricity and CO ₂ consumption by up to 80%, which also costs very little to maintain and can help solve light pollution problem.

Safety lighting ring

The system of the Shah with an electrical device structure can project dim light. This system includes LED street light, motion sensors and wireless communication equipment. At first glance, it looks like a lamp that is widely used in family gardens but has a motion sensor attached. In this system, the surrounding lights will light up if there is any object or person approaching. And the light does not turn off completely; they will keep brightness about 20% compared to standard lighting energy. When someone enters the 'safe circle' of the lamp, it will glow strongly. Another advantage is that the lights will automatically report an error to the control room. This helps make maintenance costs cheaper and more efficient today.

Introducing to the market

The purpose of this test program is to comprehensively test and complete the system, to avoid, for example, the shaking and wiping of branches or animals that pass through to turn on the light to strong light mode. The Shah is discussing with Tvilight to introduce this system to the market, and it can be profitable for him from 3 to 5 years. Shah said: ' This technique has many differences with other company's existing equipment, and the technology has been patented .' TU Delft is also looking forward to knowing the results of the experiment. Wind energy professor, Gijs van Kuik, who is very active in activities to make the campus environment more sustainable, said: ' We are very happy because of this innovation. This is a promising invention to save on street lighting . '

Chintan Shah's invention won the prize at the Campus Energy Challenge competition, a competition for students with the idea of ​​improving the efficiency of electricity use in universities. The competition is initiated by Delft Energy Intiative organization. This is the driving force for energy research and education at Delft University. It also helps promote many projects in the energy sector.
