Researchers from the Polytechnic University of Madrid (UPM), in collaboration with the Universidad Pontificia Comillas ICAI-ICADE (UPCO), have designed a new dimming system for street lighting that achieves significant energy savings, based on the combination of various electromagnetic elements, with little maintenance and a lower cost.
To meet the requirements of the latest regulation on energy efficiency for public lighting, researchers at the School of Industrial Engineering at the Polytechnic University of Madrid (UPM), in collaboration with the University Pontificia Comillas, have designed a power control system based on the combination of various electromagnetic elements, which has proven to have the capacity of efficiently reducing the luminous flux of the lamp by reducing the supply voltage thereof.
More efficient and less expensive
It is, in the researchers’ opinion, a robust system, with hardly any maintenance, efficient and with a size, weight and cost smaller than that of the control systems that are used today, based on power electronics. The system’s design has already been patent protected and is licensed to a Spanish transformers manufacturer.
Efficiency and energy savings are priorities in a society that increases its energy demand as technology progresses. If we add to this the fact that lighting accounts for approximately 50% of any municipality’s electricity consumption, the challenge of optimizing the energy consumption in public lighting systems becomes a priority. This was the challenge of a team of researchers, led by Carlos Platero at the UPM: designing a dimming system at a very low cost that achieves efficient energy savings and that is optimized for street lighting systems.
The newly designed dimming system is based on the use of electromagnetic components instead of the complex and expensive electronic equipment that have been traditionally installed. This offers a high robustness against external climatic conditions, and excellent resistance to fire, electrical shock, power surges, etc..
Maintenance requirements are negligible, much lower than those for the control systems used today. With a very simple configuration, a sole device allows regulating all the lamps included on a same line between two voltage levels and thus consumption can be efficiently reduced without thereby accelerating aging.
The manufacturing of the new device is an easy and inexpensive process that does not require very specialized work. Similarly, installation is also very simple in street lighting lines. Currently, the patented invention has already been licensed to a Spanish company manufacturer of transformers.
