Self-regulating street lights undergo tests
July 14th, 2011 - 7:07 pm ICT by IANSLondon, July 14 (IANS) New energy-saving lights which can become dim or brighten up on their own are being tested.
Maintenance-free, these smart street lights know when to brighten up or become dim, depending on human or vehicular presence. Delft University of Technology (Netherlands) which has pioneered this system, is currently trying it out in its campus.
These lights can save up to 80 percent energy.
The system comprises street lights with light-emitting diode (LEDs), motion sensors and wireless communication, which automatically dims lights when roads are completely deserted, according to a Delft statement.
Delft’s Chintan Shah designed the system, which regulates the energy levels in these lamps. They never switch off completely, but reduce the light output by 20 percent.
It will free maintenance workers from devoting hours to pinpoint systemic failures as the lamps will wirelessly inform the control room.
