The researchers say the system is strong, efficient and hardly needs any maintenance and was aimed at meeting the requirements of the latest energy efficiency of public lighting regulation. The system’s size, weight and cost are lower than systems used today based on power electronics. The system design was patented and licensed to a Spanish transformer manufacturing company.
Street lighting represents 50% of the power consumption of any city council which makes the challenge to optimize energy consumption of public lighting systems a priority. The team of researchers led by Carlos Platero of UPM have designed a regulation system of luminous flux to achieve an energy saving and low cost lighting systems thanks to their optimization.
The new regulation system of light flow is based on the usage of electromagnetic components instead of the complex and expensive electric equipments used today. Thanks to its robustness, the system can face extreme weather conditions apart from having an excellent behavior to control short-circuit, electric shock, and surges. The maintenance requirements are almost nonexistent. A single device allows the lamps control of a same line between two voltage levels efficiently decreasing its consumption without accelerating its aging.
The production of the new device is inexpensive, easy to install and it does not require skilled labor.
